Abstract
The invention relates to a safety needle assembly for injecting a fluid into a human body comprising a cylindrical housing with a bottom surface supporting a needle cannula and a shield telescopically movable relative to the housing. A spring located within the housing urges the shield in a distal needle covering direction and a locking member also provided inside the housing moves simultaneously with the shield during injection and automatically locks the shield in a position where the sharp end of the needle cannula is concealed thereby irreversible immobilizing the safety needle assembly.
Description
A Safety Needle assembly FIELD OF THE INVENTION:
The invention relates to a safety needle assembly, which reduces the risk of accidental nee-dle-stick injuries, and especially a safety needle assembly where a needle cannula is mounted in a hub.
DESCRIPTION OF RELATED ART:
Needle assemblies are commonly used to either inject substances into or extract substances out of human or animal bodies. Such needle assemblies are typically disposable and are dis-carded after only one use. The problem presented by the disposal of a needle assembly, and indeed, by any handling of the needle assembly, is the potential risk of being injured by the sharp end of the needle cannula. This is particular dangerous when following after the pene-tration of a patients skin since the needle cannula then may be contaminated and therefore capable of spreading diseases such as hepatitis and HIV.
A great number of safety needle assemblies has been developed where the needle cannula is concealed by a telescopically movable shield during the injection.
One such prior art needle protection system is disclosed in WO 01.76665. This safety needle comprises a hub with. a centrally located needle cannula. A telescopically movable shield is provided on the outside. surface of the hub. The shield is telescopically movable between a first position where it fully covers the needle cannula and a second position where a part or the needle cannula is left free to perform an injection. A cam element, rotatable mounted to the hub is provided with at least one cam, which cam is guided in cam curve provided in the inside surface of the shield. The. shield is urged in the distal direction by a spring cocked be=
tween the hub and the. shield. The cam curve is adapted to block the cam in a blocking posi-tion when the shield returns to the first position after an injection has been performed.

The problem presented by the disposal of a needle assembly, and indeed, by any handling of the needle assembly, is the potential risk of being injured by the sharp end of the needle cannula. This is particular dangerous when following after the pene-tration of a patients skin since the needle cannula then may be contaminated and therefore capable of spreading diseases such as hepatitis and HIV.
A great number of safety needle assemblies has been developed where the needle cannula is concealed by a telescopically movable shield during the injection.
One such prior art needle protection system is disclosed in WO 01.76665. This safety needle comprises a hub with. a centrally located needle cannula. A telescopically movable shield is provided on the outside. surface of the hub. The shield is telescopically movable between a first position where it fully covers the needle cannula and a second position where a part or the needle cannula is left free to perform an injection. A cam element, rotatable mounted to the hub is provided with at least one cam, which cam is guided in cam curve provided in the inside surface of the shield. The. shield is urged in the distal direction by a spring cocked be=
tween the hub and the. shield. The cam curve is adapted to block the cam in a blocking posi-tion when the shield returns to the first position after an injection has been performed.
The safety needle assembly disclosed in WO 01.76665 is however rather cumbersome and consist of a large number of parts that must be moulded and afterwards fitted together very precisely in order to obtain the correct movement of the cam follower.
It is also a fact that the difFerent plastic parts of an assembled construction have a tendency to change the relative dimensions when the construction is sterilized using steam or gas.
This is especially critical when the tolerances have to be very narrow, as in the safety needle assembly disclosed in WO 01.76665.
In order to assure that the cam element of WO 01.76665 in fact shifts into the locked position when the protective cap moves back to the initiate position after an injection has been made, a rather powerful spring is needed. This is an inconvenience for the user, since the user has to press the protective cap in the proximal direction literally with the use of his or hers skin while making the injection.
DESCRIPTION OF THE INVENTION:
It is henceforth an object of the. present invention to provide a safety needle assembly, which-overcomes the inconveniences of the prior art safety needle assemblies, and especial to provide a safety needle assembly which is made from fewer parts, and which parts are not subject to very strict tolerances.
It is further an objective of the present invention to provide a safety needle assembly having a spring with only a limited force thereby offering the user maximum comfort.
In order to overcome the drawbacks of the prior art it is suggested to provide the safety nee-dle assembly with a separate locking element located between the spring and the shield ac-cording to claim 1.
When the locking element is provided as a separate element located between the spring and the shield and moved simultaneously with the. shield, the locking protrusion can be guided during the longitudinal movement of the locking member thereby eliminating the need. for tracks or cams thus making it possible to. construct the safety needle assembly from only three plastic part in addition to. the hub.

It is further an objective of the present invention to provide a safety needle assembly having a spring with only a limited force thereby offering the user maximum comfort.
In order to overcome the drawbacks of the prior art it is suggested to provide the safety nee-dle assembly with a separate locking element located between the spring and the shield ac-cording to claim 1.
When the locking element is provided as a separate element located between the spring and the shield and moved simultaneously with the. shield, the locking protrusion can be guided during the longitudinal movement of the locking member thereby eliminating the need. for tracks or cams thus making it possible to. construct the safety needle assembly from only three plastic part in addition to. the hub.
Since there are no tracks or cams as such the internal tolerances are not that important, and the friction can be kept rather low which renders it possible to utilize a somewhat soft spring, which enhances the user comfort.
By blocking the rotational movement of the locking protrusion with a fin provided on the in-side surface of the housing as specified in claim 2, it is possible to define when the rotatable movement of the locking protrusion should commence simply by specifying a specific length of the fin.
Once the locking protrusion on the locking element has passed over the end of the fin as specified in claim 3 it will be impossible to move the locking protrusion backwards. The length of the fins can be made such that once the shield has been activated and the needle cannula has emerged from the opening in the shield it will be impossible to abort the injection and keep the needle for later use.
When the locking protrusion engages the. toothed ring of the shield as defined in claim 4, the shield can be moved all the way back in the proximal direction thereby uncovering the needle cannula.
When the injection is over and the locking protrusion is arrested in the opening in the longitu-dinal rib as mentioned in claim 5, it is virtually impossible to advance the needle cannula again by pressing the shield backwards in the proximal direction.
The guiding means for guiding the locking protrusion comprises only horizontally difined. ribs and fins as specified in claim 6. This makes both the moulding of the parts and the assembly of the parts very simple.
By mounting the shield inside. the housing as disclosed in claim 7, it is ensured that the shield cannot be separated from the housing.
When the spring cocked between the locking. element and the hub interfaces both the locking element and the bottom surface of the housing as revealed in claim 8, it is ensured that the spring can be added to the assembly in a very simple manner.
By blocking the rotational movement of the locking protrusion with a fin provided on the in-side surface of the housing as specified in claim 2, it is possible to define when the rotatable movement of the locking protrusion should commence simply by specifying a specific length of the fin.
Once the locking protrusion on the locking element has passed over the end of the fin as specified in claim 3 it will be impossible to move the locking protrusion backwards. The length of the fins can be made such that once the shield has been activated and the needle cannula has emerged from the opening in the shield it will be impossible to abort the injection and keep the needle for later use.
When the locking protrusion engages the. toothed ring of the shield as defined in claim 4, the shield can be moved all the way back in the proximal direction thereby uncovering the needle cannula.
When the injection is over and the locking protrusion is arrested in the opening in the longitu-dinal rib as mentioned in claim 5, it is virtually impossible to advance the needle cannula again by pressing the shield backwards in the proximal direction.
The guiding means for guiding the locking protrusion comprises only horizontally difined. ribs and fins as specified in claim 6. This makes both the moulding of the parts and the assembly of the parts very simple.
By mounting the shield inside. the housing as disclosed in claim 7, it is ensured that the shield cannot be separated from the housing.
When the spring cocked between the locking. element and the hub interfaces both the locking element and the bottom surface of the housing as revealed in claim 8, it is ensured that the spring can be added to the assembly in a very simple manner.
By providing the housing with a window through which the locking protrusion can be viewed when it is in the arrested position, it is ensured that a user can visible inspect whether the safety needle assembly has been used before or not.
The part of the shield and/or the locking element that are visible through the window when the safety needle assembly is in the unused condition can also be coloured in a colour indi-Gating that the safety needle assembly is ready for use.
The window can either be transparent or simply an opening in the sidewall of the housing.
In the present context, the term "moving simultaneous" which are used to describe the rela-tionship between the movement of the shield and the locking element, does not necessary mean that the shield and the locking protrusion moves with the same speed. The relative speed of movement is defined by the various angled surfaces, and is therefore variable. The term "moving simultaneously" merely means that both the shield and the locking protrusion move at the same time.

Detailed Description of Embodiment:
Initially it may be convenient to define that, the term "distal end" is meant to refer to the end of the safety needle assembly inserted into the patient, whereas the term "proximal end" is meant to refer to the end connected to the injection device.
Figure 1 shows a safety needle assembly comprising a housing 1 and a shield 2, the housing 1 is made up from a hub 3 and a body 4. The hub 3 and the body 4 is normally glued or welded together.
The connecting surface 5 between the hub 3 and the body 4 is in the figures shown in a spe-cific position, but could off cause be located as wanted. The hub 3 and the body 4 could even be moulded as one piece closed at the top surface 6 by a lit. The top surface 6 is provided with an opening 8 through which the shield 2 appears.
The shield 2 is provided with a needle outlet 7 through which the needle cannula 30 can penetrate. The proximal end of the shield 2 is, as shown in figure 2, provided with eight out-wardly projecting studs 10, which studs 10 has a planar fore front 11 and an angled back front 12.
20. The housing 1 has a bottom surface 9 in the centre of which the needle cannula 30 is mounted. The needle cannula 30 can either be mounted such that a part of needle cannula 30 projects from the bottom surface 9 in the proximal direction, which is preferred for use with. cartridges, or it can be mounted. without this so called back needle, which is preferred for hypodermic syringes. Adjacent the bottom surface 9, at the proximal end of the housing 1, means are provided for mounting the safety needle assembly on to an injection device.
These means would normally be a thread 35 such that the safety needle assembly can be screwed onto a pen syringe.
Figure 3 shows the shield 2 seen from the proximal end. The eight studs 10 are separated from each other by eight equally sized spaces 26. The angular back front 12 of the studs 10 forms together with the shield 2 a toothed ring 13 where the centre of the studs 10 forms the.
tops and the shield 10 within the spaces 26 farms the valleys.

The body 4 of the housing 1 is in figure 5 shown in perspective and in figure 6 in a sectional view. The body 4 is provided with four windows 20 and one longitudinal rib 21 for each win-dow 20. The ribs 21 are provided on the inside surface of the body 4. These longitudinal ribs 21 extend through the entire length of the body 4 although divided into two parts (21 a, 21 b) by the windows 20. The distal part of this rib 21 is moulded uniform with a collar 24 provided at the distal end of the body 4 and terminates in a planar surface 14 at the distal end of the window 20. The proximal part of the rib 21 terminates at the proximal end of the window in a blocking surface 15, the use of which will be explained later. At the distal end of the body 4 there is provided four fins 22. These fins 22 is moulded uniform with the collar 24 at the distal end of the body 4, and has at the proximal end an angled surface 23 which terminates ap-proximately in a position adjacent the middle of the windows 20.
Although the embodiment here described has eight studs 10, four locking protrusions 17 and four windows 20, these parts could be provided in a different number, as shown in figure 15.
When the safety needle assembly shown in figure 2 is assembled, a spring 25 is cocked be-tween the bottom surface 9 of the housing 1 and. the locking element 16 urging the locking element 16 and the shield 2 in a distal direction. The planar forefront 11 on the studs 10 abuts the collar 24 such that the shield. 2 is connected to the body 4 of the housing 1.
The. assembled safety needle assembly is shown in figure 7 and 8. Figure 8 illustrates the inside of the safety needle assembly with the body 4 cut away.
The shield 2 is located such within the body 4 of the housing 1 that each rib 21 and each fin 22 is located in the space 26 between two studs 10. The upper part 21 a of the ribs 21. are however not shown in figure 8, since this upper rib 21 a is not entirely necessary. The locking element 16 is thereafter mounted such that the angular forefront 18 on each locking protru-sion 17 abuts the angled back front 12 on four of the studs 10 of the shield 2, whereby the side surface of the locking protrusion 17 and the side surface of the studs 10 forms a straight line which line abuts the side surface of the fins 22 of the body 4 of the housing 1.
Once the shield 2 and the locking element 16 is correctly mounted within the body 4 of the housing 1, the spring 25 is located around the needle cannula 30 and the body 4 and the hub 3 are sealed together, rendering the safety needle assembly ready for use.
The movement of the locking protrusion 17 is schematically shown in figure 9 -12, showing the relative position of one of the locking protrusion 17 on the locking element 16, two of the studs 10 on the shield 2, one of the fins 22 on the inside surface of the body 4 of the housing 1 and one of the ribs 21 also located on the inside surface of the body 4 of the housing 1.
Figure 9 illustrates the safety needle assembly in its initial position, as shown in figure 8, with the shield 2 in its distal position where the shield 2 covers the needle cannula 30. When the shield 2 is pressed towards the skin of a user, the shield 2 and with it the studs 10, are moved in a proximal direction as indicated with the arrow 27. This movement also moves the locking protrusion 17 on the locking element 16 in the proximal direction against the force F
of the spring 25.
Once the locking protrusions 17 is moved free of the fins 22, as shown in figure 10, the an-gled fore front 18 of the locking protrusions 17 will slide along the angled back front 12 of the studs 10 and the angled fore front 23 of the fins 22 as indicated with the arrow 28. This movement will move the locking protrusions 17 into contact with the valleys of the toothed . ring 13.. Further movement of the shield 2 and thereby the studs 10 in the direction of the ar-row 27 will only move the locking protrusions 17 further in the proximal direction. The injec-tion is then executed with the shield 2 in its most proximal direction. The position of the fins 22 and the ribs. 21 is such that the studs 10 are always guided either by the fins 22 or by the ribs 21.
When the injection is over, the needle cannula 30 is retracted from the skin of the user, which will cause the shield 2 with the studs 10 and the locking element 16 with the locking protru sion 17 to move in the distal direction due to the impact of the force F
executed by the spring 30. 25. The arrow 29 in figure 11 indicates this movement.
Figure 12 illustrates how the force F of the spring 25 urges the locking element 16 with the locking protrusion 17 and the shield 2 with the studs 10 in the distal direction. When the an-gled fore front 23 on the fins 22 aligns the angled back front 12 of the studs 10, such that the two angled fore fronts 23, 12 form a diagonal line, the angled fore front 18 of the locking pro-trusion 17 will slide along this line into a position where the locking protrusion 17 is located between the upper part 21 a and the lower part 21 b of the ribs 21 i.e.
between the planar sur-face 14 of the upper part 21 a of the ribs 21 and the blocking surface 15 of the lower part 21 b of the. ribs 21. In this position the locking protrusion 17 and hence the locking element 16 and the shield 2 is irreversible locked.
At the proximal end of the locking protrusion 17, the planar back front 19 will abut or at least be blocked by the blocking surface 15 on the ribs 21 of the body 4 of the housing 1, thereby rendering it impossible to move the shield 2 in the proximal direction. At the distal end, the angled fore front 18 of the locking protrusion 17 will abut the toothed ring 13 of the shield 2 and since the planar forefront 11 of the studs 10 on the shield 2 abuts the collar 24 of the body 4 of the housing 1 it will not be possible to move the shield 2 in the distal direction.
Sideways the studs 10 of the shield 2 will be arrested between the upper part 21 a of the ribs 21 and the fins 22. As a result of this it will be impossible to move the shield 2 in any direc-tion.
Instead of having the angled fore front 18 of the locking protrusion 17 in abutment with the toothed ring 13 of the shield when the injection is over, the front end 36 of the locking ele-ment 16 can be design to abut the inner top end 37 of shield 2 once the locking protrusion 17 is in the locking position. This will make it virtually impossible to squeeze the angled fore front 18 of the locking protrusion 17 by pushing he shield 2 in the proximal direction.
. The body 4 of the housing 1 is provided with four windows 20 which windows 20 divides each of the four ribs 21 into an upper part 21a and a lower part 21 b. When the safety needle assembly has been used, the locking protrusion 17 on the locking element 16 will be located between the upper part 21 a and the. lower part 21 b of the ribs 21, and will thus be visible through the window 20. The locking protrusion 17, or a part of it, could be coloured in an in-flammatory colour, or provided with another indication, which will render it very easy for a user to visibly inspect whether the safety needle. assembly has been used or not just by glancing at the windows 20. The windows 20 could e.g. be provided as openings in the wall of the body 4.
Prior to use, the safety needle assembly is delivered to the user sterilized and contained as is shown in figure 7. The container 31 is closed at the distal surface 32 and open at the proximal surface 33. The proximal surface 33 is sealed by a not shown removable seal. The container 31 has on the inside surface not shown ribs that mates ribs 34 located on the out-side surface of the housing 1 preferably on the hub 3, such that the safety needle assembly can be screwed on and off a pen syringe without removing the container 32 from the safety needle assembly. Further the container could on the inside surface be provided with a num-5 ber of not shown raised points supporting the safety needle assembly in a somewhat floating position making it easier for the steam or gas to fully surround the safety needle assembly during sterilization in case this type of sterilization is used.
The spring 30 urging the locking element 16 and the shield 2 in the distal direction is prefera-10 bly made from stainless non-corrosive steel such that the spring 30 will not be damaged dur-ing the steam sterilization process. A spring 30 particular suitable for this purpose is a 1.4462/SAF2205 spring.
Another embodiment of the safety needle assembly according to the invention is disclosed in figure 13 and figure 14.
Figure 13 shows a housing 40 comprising of a hub 41 and body 42. Mounted inside the housing 40 are a shield 43 and a locking element 44. The shield 43 penetrates out of the housing 40 through an opening 45 located at the distal end of the housing 40 The shield 43 is provided with four studs 46 and ends at the proximal end in a toothed ring 38.
This toothed ring 38 engages a second toothed ring 39 located on the locking element 44.
The locking element 44 is further provided with a locking protrusion 49 located at the proxi-mal end thereof.
The needle cannula 30 is in figure 13 mounted in the bottom surface 50, which bottom sur-face 50 is. provided in the housing 40, preferably in the hub 41.
30.
Figure 13 shows the safety needle assembly with the shield 43 in the locked position, and figure 14 illustrates the inside surface of the housing 40. by showing the part of the housing 40. cut away in figure 13 seen from the backside.
The four studs 46 on the shield 43 is guided in first horizontal tracks 51 provided on the in-side surface of the housing 40. The locking protrusion 49 on the locking.
element 44 abuts a planar surface 48 in its initiate position and is guided in a second horizontal track 52 as the shield 43 is moved in the proximal direction. Once the shield 43 has been moved all the way back to its most proximal position and the injection is executed, a not shown spring posi-tinned between the bottom surface 50 and the locking element 44 will urge the locking ele-ment 44 and hence the shield 43 in the distal direction. During this movement, the angled fore front 47 of the locking protrusion 49 will engage a diagonal track 53 also provided in the inside surface of the housing 40. While the shield 43 moves back to its initiate position, the locking element 44 and hence the locking protrusion 49 will rotate approximately 180 de-grees in the diagonal track 53 and engage a locking chamber 54 provided at the distal end of the diagonal track 53, which locking chamber 54 has a blocking surface 55 that a planar back front 56 of the locking protrusion 49 will abut rendering further movement of the shield 43 im-possible. The first toothed ring 38 of the shield 43 and the second toothed ring 39 of the lock-ing element 44 support this movement due to mutual. engagement of the angled surfaces of the two rings 38, 39.
The shield 43 cannot be rotated relatively to the housing 40 due to the engagement of the studs 46 with the first horizontal tracks 51. Since rotation of the shield 43 is inhibited it is im-possible to rotate the locking protrusion 49 of the locking element 44 backwards in the di-agonal track 53, and the locking protrusion 49 will therefore remain in the locking chamber 54 thus rendering the safety needle assembly secured.
A window could be provided in the housing 40 through which window the locking chamber 54 can be viewed, such that the user can get a visible indication whether the.
safety needle as-sembly has been used or not.
An improved embodiment of the safety needle assembly disclosed in figure 1 to 12 is shown in figure 15 and in figure 16.
In the following the numbers. referring to the same element as in the previous figures has been given the same number plus one hundred.
The safety needle assembly shown in figure 15 comprises a housing made up from a needle 35. hub 103 and a body 104 both preferably injection moulded from PP. Both the hub 103 itself and the tower of the hub 103 is somewhat higher than shown in figure 2, while the body 104 is somewhat shorter. The needle cannula 130 is inserted in the tower of the hub 103 and glued to the hub 103 by a blob of glue 160.
The body 104 is in this embodiment provided with three windows 120 and the locking ele-ment 116 is also provided with three locking protrusions 117. When the locking element 116 locks the safety needle assembly from reuse, the three locking protrusions 117 will be visible in the three windows 120 as earlier explained The shield 104 which is preferably made from TPX can be transparent such that the tip of needle cannula 130 is visible for inspection by the user prior to injection, has on its proximal end six studs 110. The toothed ring 113 formed between these studs 110 is therefore in this embodiment only provided with six valleys.
The locking element 116 which is preferably made from POM or PP is on the distal end sur-face provided with a serrated ring 161 which are used during the manufacturing process.
When the safety needle assembly is being assembled a tool can enter the safety needle as-sembly through the needle outlet 107 in the shield 102 and engage this serrated ring 161 in order to rotate the locking element 116 to the correct position before the shield 102 and the locking element 116 is permanently encapsulated in the housing. For this purpose the needle outlet 107 needs to be large enough for the toll to pass through the needle outlet 107.
In the embodiment shown in figure 10 there exist a slight possibility of rotating the. shield 2 when the studs 10 are longitudinal located. between the fins 22 and the lower part 21 b of the ribs 21.. In order to prevent such accidental rotation, the studs 110 of the embodiment shown in figure 15 is provided with an additional guiding rib 162 which are guided in. a number of not shown guiding tracks provided on the inside surFace of the body 104 of the housing. Due to this no rotation between the shield 102 and the body 104. is possible, When the safety needle assembly is. assembled the whole unit is packed in a container 131 which container 131 is sealed with a removable seal 163 and sterilized. The.
removable seal 163 is preferably made from paper.
The distal part of the container 131. can be formed as a cup 164 holding a predetermined volume as shown in figure 16. The dosage of an injection device to be used with the safety needle assembly can thus be controlled by ejecting a predetermined number of doses into the cup 164 and verifying the expelled volume. This can be done either by filling the entire cup or by having indications printed on the cup 164.
Some preferred embodiments have been shown in the foregoing, but it should be stressed that the invention is not limited to these, but may be embodied in other ways within the sub-ject matter defined in the following claims.

The body 4 of the housing 1 is in figure 5 shown in perspective and in figure 6 in a sectional view. The body 4 is provided with four windows 20 and one longitudinal rib 21 for each win-dow 20. The ribs 21 are provided on the inside surface of the body 4. These longitudinal ribs 21 extend through the entire length of the body 4 although divided into two parts (21 a, 21 b) by the windows 20. The distal part of this rib 21 is moulded uniform with a collar 24 provided at the distal end of the body 4 and terminates in a planar surface 14 at the distal end of the window 20. The proximal part of the rib 21 terminates at the proximal end of the window in a blocking surface 15, the use of which will be explained later. At the distal end of the body 4 there is provided four fins 22. These fins 22 is moulded uniform with the collar 24 at the distal end of the body 4, and has at the proximal end an angled surface 23 which terminates ap-proximately in a position adjacent the middle of the windows 20.
Although the embodiment here described has eight studs 10, four locking protrusions 17 and four windows 20, these parts could be provided in a different number, as shown in figure 15.
When the safety needle assembly shown in figure 2 is assembled, a spring 25 is cocked be-tween the bottom surface 9 of the housing 1 and. the locking element 16 urging the locking element 16 and the shield 2 in a distal direction. The planar forefront 11 on the studs 10 abuts the collar 24 such that the shield. 2 is connected to the body 4 of the housing 1.
The. assembled safety needle assembly is shown in figure 7 and 8. Figure 8 illustrates the inside of the safety needle assembly with the body 4 cut away.
The shield 2 is located such within the body 4 of the housing 1 that each rib 21 and each fin 22 is located in the space 26 between two studs 10. The upper part 21 a of the ribs 21. are however not shown in figure 8, since this upper rib 21 a is not entirely necessary. The locking element 16 is thereafter mounted such that the angular forefront 18 on each locking protru-sion 17 abuts the angled back front 12 on four of the studs 10 of the shield 2, whereby the side surface of the locking protrusion 17 and the side surface of the studs 10 forms a straight line which line abuts the side surface of the fins 22 of the body 4 of the housing 1.
Once the shield 2 and the locking element 16 is correctly mounted within the body 4 of the housing 1, the spring 25 is located around the needle cannula 30 and the body 4 and the hub 3 are sealed together, rendering the safety needle assembly ready for use.
The movement of the locking protrusion 17 is schematically shown in figure 9 -12, showing the relative position of one of the locking protrusion 17 on the locking element 16, two of the studs 10 on the shield 2, one of the fins 22 on the inside surface of the body 4 of the housing 1 and one of the ribs 21 also located on the inside surface of the body 4 of the housing 1.
Figure 9 illustrates the safety needle assembly in its initial position, as shown in figure 8, with the shield 2 in its distal position where the shield 2 covers the needle cannula 30. When the shield 2 is pressed towards the skin of a user, the shield 2 and with it the studs 10, are moved in a proximal direction as indicated with the arrow 27. This movement also moves the locking protrusion 17 on the locking element 16 in the proximal direction against the force F
of the spring 25.
Once the locking protrusions 17 is moved free of the fins 22, as shown in figure 10, the an-gled fore front 18 of the locking protrusions 17 will slide along the angled back front 12 of the studs 10 and the angled fore front 23 of the fins 22 as indicated with the arrow 28. This movement will move the locking protrusions 17 into contact with the valleys of the toothed . ring 13.. Further movement of the shield 2 and thereby the studs 10 in the direction of the ar-row 27 will only move the locking protrusions 17 further in the proximal direction. The injec-tion is then executed with the shield 2 in its most proximal direction. The position of the fins 22 and the ribs. 21 is such that the studs 10 are always guided either by the fins 22 or by the ribs 21.
When the injection is over, the needle cannula 30 is retracted from the skin of the user, which will cause the shield 2 with the studs 10 and the locking element 16 with the locking protru sion 17 to move in the distal direction due to the impact of the force F
executed by the spring 30. 25. The arrow 29 in figure 11 indicates this movement.
Figure 12 illustrates how the force F of the spring 25 urges the locking element 16 with the locking protrusion 17 and the shield 2 with the studs 10 in the distal direction. When the an-gled fore front 23 on the fins 22 aligns the angled back front 12 of the studs 10, such that the two angled fore fronts 23, 12 form a diagonal line, the angled fore front 18 of the locking pro-trusion 17 will slide along this line into a position where the locking protrusion 17 is located between the upper part 21 a and the lower part 21 b of the ribs 21 i.e.
between the planar sur-face 14 of the upper part 21 a of the ribs 21 and the blocking surface 15 of the lower part 21 b of the. ribs 21. In this position the locking protrusion 17 and hence the locking element 16 and the shield 2 is irreversible locked.
At the proximal end of the locking protrusion 17, the planar back front 19 will abut or at least be blocked by the blocking surface 15 on the ribs 21 of the body 4 of the housing 1, thereby rendering it impossible to move the shield 2 in the proximal direction. At the distal end, the angled fore front 18 of the locking protrusion 17 will abut the toothed ring 13 of the shield 2 and since the planar forefront 11 of the studs 10 on the shield 2 abuts the collar 24 of the body 4 of the housing 1 it will not be possible to move the shield 2 in the distal direction.
Sideways the studs 10 of the shield 2 will be arrested between the upper part 21 a of the ribs 21 and the fins 22. As a result of this it will be impossible to move the shield 2 in any direc-tion.
Instead of having the angled fore front 18 of the locking protrusion 17 in abutment with the toothed ring 13 of the shield when the injection is over, the front end 36 of the locking ele-ment 16 can be design to abut the inner top end 37 of shield 2 once the locking protrusion 17 is in the locking position. This will make it virtually impossible to squeeze the angled fore front 18 of the locking protrusion 17 by pushing he shield 2 in the proximal direction.
. The body 4 of the housing 1 is provided with four windows 20 which windows 20 divides each of the four ribs 21 into an upper part 21a and a lower part 21 b. When the safety needle assembly has been used, the locking protrusion 17 on the locking element 16 will be located between the upper part 21 a and the. lower part 21 b of the ribs 21, and will thus be visible through the window 20. The locking protrusion 17, or a part of it, could be coloured in an in-flammatory colour, or provided with another indication, which will render it very easy for a user to visibly inspect whether the safety needle. assembly has been used or not just by glancing at the windows 20. The windows 20 could e.g. be provided as openings in the wall of the body 4.
Prior to use, the safety needle assembly is delivered to the user sterilized and contained as is shown in figure 7. The container 31 is closed at the distal surface 32 and open at the proximal surface 33. The proximal surface 33 is sealed by a not shown removable seal. The container 31 has on the inside surface not shown ribs that mates ribs 34 located on the out-side surface of the housing 1 preferably on the hub 3, such that the safety needle assembly can be screwed on and off a pen syringe without removing the container 32 from the safety needle assembly. Further the container could on the inside surface be provided with a num-5 ber of not shown raised points supporting the safety needle assembly in a somewhat floating position making it easier for the steam or gas to fully surround the safety needle assembly during sterilization in case this type of sterilization is used.
The spring 30 urging the locking element 16 and the shield 2 in the distal direction is prefera-10 bly made from stainless non-corrosive steel such that the spring 30 will not be damaged dur-ing the steam sterilization process. A spring 30 particular suitable for this purpose is a 1.4462/SAF2205 spring.
Another embodiment of the safety needle assembly according to the invention is disclosed in figure 13 and figure 14.
Figure 13 shows a housing 40 comprising of a hub 41 and body 42. Mounted inside the housing 40 are a shield 43 and a locking element 44. The shield 43 penetrates out of the housing 40 through an opening 45 located at the distal end of the housing 40 The shield 43 is provided with four studs 46 and ends at the proximal end in a toothed ring 38.
This toothed ring 38 engages a second toothed ring 39 located on the locking element 44.
The locking element 44 is further provided with a locking protrusion 49 located at the proxi-mal end thereof.
The needle cannula 30 is in figure 13 mounted in the bottom surface 50, which bottom sur-face 50 is. provided in the housing 40, preferably in the hub 41.
30.
Figure 13 shows the safety needle assembly with the shield 43 in the locked position, and figure 14 illustrates the inside surface of the housing 40. by showing the part of the housing 40. cut away in figure 13 seen from the backside.
The four studs 46 on the shield 43 is guided in first horizontal tracks 51 provided on the in-side surface of the housing 40. The locking protrusion 49 on the locking.
element 44 abuts a planar surface 48 in its initiate position and is guided in a second horizontal track 52 as the shield 43 is moved in the proximal direction. Once the shield 43 has been moved all the way back to its most proximal position and the injection is executed, a not shown spring posi-tinned between the bottom surface 50 and the locking element 44 will urge the locking ele-ment 44 and hence the shield 43 in the distal direction. During this movement, the angled fore front 47 of the locking protrusion 49 will engage a diagonal track 53 also provided in the inside surface of the housing 40. While the shield 43 moves back to its initiate position, the locking element 44 and hence the locking protrusion 49 will rotate approximately 180 de-grees in the diagonal track 53 and engage a locking chamber 54 provided at the distal end of the diagonal track 53, which locking chamber 54 has a blocking surface 55 that a planar back front 56 of the locking protrusion 49 will abut rendering further movement of the shield 43 im-possible. The first toothed ring 38 of the shield 43 and the second toothed ring 39 of the lock-ing element 44 support this movement due to mutual. engagement of the angled surfaces of the two rings 38, 39.
The shield 43 cannot be rotated relatively to the housing 40 due to the engagement of the studs 46 with the first horizontal tracks 51. Since rotation of the shield 43 is inhibited it is im-possible to rotate the locking protrusion 49 of the locking element 44 backwards in the di-agonal track 53, and the locking protrusion 49 will therefore remain in the locking chamber 54 thus rendering the safety needle assembly secured.
A window could be provided in the housing 40 through which window the locking chamber 54 can be viewed, such that the user can get a visible indication whether the.
safety needle as-sembly has been used or not.
An improved embodiment of the safety needle assembly disclosed in figure 1 to 12 is shown in figure 15 and in figure 16.
In the following the numbers. referring to the same element as in the previous figures has been given the same number plus one hundred.
The safety needle assembly shown in figure 15 comprises a housing made up from a needle 35. hub 103 and a body 104 both preferably injection moulded from PP. Both the hub 103 itself and the tower of the hub 103 is somewhat higher than shown in figure 2, while the body 104 is somewhat shorter. The needle cannula 130 is inserted in the tower of the hub 103 and glued to the hub 103 by a blob of glue 160.
The body 104 is in this embodiment provided with three windows 120 and the locking ele-ment 116 is also provided with three locking protrusions 117. When the locking element 116 locks the safety needle assembly from reuse, the three locking protrusions 117 will be visible in the three windows 120 as earlier explained The shield 104 which is preferably made from TPX can be transparent such that the tip of needle cannula 130 is visible for inspection by the user prior to injection, has on its proximal end six studs 110. The toothed ring 113 formed between these studs 110 is therefore in this embodiment only provided with six valleys.
The locking element 116 which is preferably made from POM or PP is on the distal end sur-face provided with a serrated ring 161 which are used during the manufacturing process.
When the safety needle assembly is being assembled a tool can enter the safety needle as-sembly through the needle outlet 107 in the shield 102 and engage this serrated ring 161 in order to rotate the locking element 116 to the correct position before the shield 102 and the locking element 116 is permanently encapsulated in the housing. For this purpose the needle outlet 107 needs to be large enough for the toll to pass through the needle outlet 107.
In the embodiment shown in figure 10 there exist a slight possibility of rotating the. shield 2 when the studs 10 are longitudinal located. between the fins 22 and the lower part 21 b of the ribs 21.. In order to prevent such accidental rotation, the studs 110 of the embodiment shown in figure 15 is provided with an additional guiding rib 162 which are guided in. a number of not shown guiding tracks provided on the inside surFace of the body 104 of the housing. Due to this no rotation between the shield 102 and the body 104. is possible, When the safety needle assembly is. assembled the whole unit is packed in a container 131 which container 131 is sealed with a removable seal 163 and sterilized. The.
removable seal 163 is preferably made from paper.
The distal part of the container 131. can be formed as a cup 164 holding a predetermined volume as shown in figure 16. The dosage of an injection device to be used with the safety needle assembly can thus be controlled by ejecting a predetermined number of doses into the cup 164 and verifying the expelled volume. This can be done either by filling the entire cup or by having indications printed on the cup 164.
Some preferred embodiments have been shown in the foregoing, but it should be stressed that the invention is not limited to these, but may be embodied in other ways within the sub-ject matter defined in the following claims.
