- FIG. 1 depicts, in perspective, a syringe 1 and a protection assembly 2 .
- proximal and rear are synonymous, as are the terms “distal” and “front”.
- the syringe 1 is a glass syringe of standard format, intended for single use. It contains a liquid to be injected intramuscularly or subcutaneously into a patient. For this purpose it comprises a body 4 , a needle 6 secured to the distal end of the body 4 and a piston 8 .
- This piston in the conventional way comprises a rod 10 provided at its distal end with a plunger 12 visible in FIG. 6A and with a bearing head 14 against which the thumb of the practitioner's hand is intended to bear.
- the body 4 of the syringe comprises, in its proximal part, a neck 16 circumferentially delimiting two diametrically opposed lugs 18 intended, normally, particularly when the assembly 2 is not present, to form bearing surfaces for the index and middle finger of the practitioner when he or she is handling the syringe and injecting the liquid located therein.
- the protection assembly 2 of overall axis X-X, essentially and as depicted in FIG. 1 , comprises:
- a protective sleeve 22 arranged coaxially with respect to the support 20 and of a diameter greater than that of the support
- the support 20 comprises a more or less cylindrical main section 26 , having an internal diameter more or less equal to the external diameter of the body 4 of the syringe.
- This section 26 is extended at its proximal end by a secondary section 28 of larger internal and external diameters and those of the main section 26 , thereby forming a radial shoulder 29 .
- the proximal section 28 is provided with means 30 of attachment to the neck of the syringe 16 . More specifically, these means 30 comprise diametrically opposed deformable hooks 32 , also visible in FIG. 1 . Each of these hooks forms a more or less frustoconical ramp surface 32 A widening towards the free end of the section 28 which is intended to be pushed back elastically by the lugs 18 of the neck of the syringe 16 when the support 20 is fixed onto the syringe 1 . The distance from the hooks 32 to the shoulder 29 is more or less equal to the thickness of the lugs 18 . The hooks 32 thus form a means of clipping onto the neck of the syringe 16 .
- Each slot consists of a straight first part 38 which runs more or less along the axis X-X of the support 20 over a length greater than that of the needle 6 , and of a straight second part 40 , which runs at an angle to the same axis X-X.
- the inclined part 40 opens into the proximal end of the straight first part 38 , forming a V, the vertex of which points toward the proximal end of the assembly 2 .
- the main section 26 at its distal end comprises a first pair of diametrically opposed elastic tabs 42 each one situated in the continuation of the slots 36 ( FIG. 5 ).
- These tabs 42 have an internal face 42 A of more or less cylindrical shape and an external face 42 B that is more or less frustoconical, widening towards the rear end.
- the main section 26 comprises a pair of diametrically opposed external ramps 44 situated between the elastic tabs 42 around the circumference of the distal end of this section. They have a more or less frustoconical inclined external surface 44 A diverging towards the front end, and a more less flat distal surface 44 B. The external surfaces 44 A thus face towards the recesses 26 A.
- Longitudinal recesses 26 A are formed in the main section 26 ( FIG. 3 ) at the proximal end of these ramps 44 .
- axial slits 26 B are provided originating from the distal end of the support so that before the body 4 of the syringe 1 is inserted in the support 20 , these tabs 42 can be deformed radially, particularly inwards.
- the protective sleeve 22 is of a length more or less equal to that of the body 4 of the syringe 1 . It consists of two cylindrical sections 46 and 48 , the main section 46 being of a diameter slightly greater than that of the main section 48 . These two sections meet to form a radial shoulder 49 .
- the sleeve 22 comprises, as an integral part in its proximal part, an external flange 50 in the form of two diametrically opposed lugs 52 ( FIG. 4 ).
- two diametrically opposed studs 54 are secured to the sleeve ( FIG. 5 ). These two studs are accommodated and guided in the two slots 36 of the support 20 respectively.
- the support and the sleeve can thus move one relative to the other in terms of translation along their common axis and in terms of limited rotation about the same axis when the studs lie in the inclined parts 40 .
- the inclined parts 40 therefore form pockets that retain the studs 54 , these pockets having a retention depth denoted p in FIG. 3 . This depth is measured along the axis of the protector.
- the support 20 and the sleeve 22 can move between a position in which the sleeve is retracted, in which position most of the sleeve covers most of the support and the studs 54 lie at the distal end of each of the inclined slot parts 40 , as depicted in FIGS. 2 to 7 , and a position in which the sleeve is deployed, in which position the sleeve projects axially from the support and the studs lie at the distal end of the straight slot part 38 , as depicted in FIGS. 11 to 13 .
- these extreme positions correspond respectively to an injection configuration in which the needle 6 of the syringe 1 is uncovered and intended to be inserted into a patient, and to a protection configuration in which this needle is surrounded by the protective sleeve 22 .
- the proximal part of the sleeve 22 also internally comprises a pair of diametrically opposed deformable longitudinal hooks 56 . These hooks are delimited within the sleeve 22 by lateral slits. These hooks are connected to the sleeve at their distal end. Each hook at its proximal free end has an internal protrusion.
- each protrusion has a front face 56 A of more or less frustoconical shape diverging from the axis of the sleeve 22 towards the front. These front faces 56 A thus face the front end of the protector.
- Each front face 56 A is designed to collaborate with an inclined surface 44 A formed by the ramps 44 of the support.
- each interior protrusion has an inclined rear face 56 B facing towards the rear end of the protector and, in particular, towards the two lugs 52 .
- These surfaces 56 B are generally frustoconical and diverge from one another towards the rear end of the protector.
- the support 20 comprises frustoconical ramps 57 arranged to the rear of the recesses 26 A. These ramps are inclined towards the recesses 26 A and designed to collaborate with the inclined rear faces 56 B.
- each hook 56 has an inclined transverse surface or 56 C forming an end stop.
- each hook lies immediately facing the corresponding end of the recess 26 A.
- the distance d separating the end face 56 C from the edge of the recess is shorter than the depth p of the retention pocket formed of the inclined slot part 40 in which the peg 54 is held.
- the hooks 56 lie inside the recesses 26 A formed in the support 20 .
- the end faces 56 C of the hooks 56 are axially in abutment against the tabs 44 , the hooks and tabs thereby providing a rigid immobilization assembly in the deployed position.
- the sleeve 22 is also provided at its distal end with a ring of deformable tabs 58 , the distal edges of which form a more or less circular opening 60 of a diameter smaller than the internal diameter of the main section 26 of the support 20 .
- the spring 24 is a spiral-wound spring, located between the protective sleeve 22 and the protector support 20 . More specifically, the spring is housed between the shoulder 29 of the support 20 and the shoulder 49 of the sleeve 22 . When the sleeve is in the retracted position, the spring 24 is in a compressed state, thus having relaxation energy connected with the stiffness of the spring and with the difference between the length of the spring in the state of rest and its length, marked L in FIGS. 2 to 7 , in the compressed state. What this amounts to saying is that the spring 24 exhibits an additional compression force threshold which corresponds to the minimum force needed to compress the spring further from its initial compressed state of FIGS. 2 to 7 .
- the spring stiffness and/or the initial compression length L are chosen so that this force threshold is higher than the pressure force needed to move the piston 8 of the syringe 1 over its entire injection travel. More specifically, the force of the spring in the locked state is greater than the sum of the injection force, that is to say the force needed to expel the liquid from the needle 6 of the syringe 1 , and the forces required to overcome the stiction of the plunger 12 and cause it to slide inside the body 4 of the syringe.
- the protection assembly 2 further comprises a cap 66 of tubular overall shape, depicted in FIGS. 1 and 6 A.
- the cap 66 is designed to surround the needle 6 before the syringe 1 is used.
- This cap is closed at one of its ends and its opposite end is formed of an annular ring 68 of an outside diameter tailored to be both a match with the surface 42 A of the hooks 42 of the support 20 and greater than the diameter of the opening 60 formed by the tabs 58 of the protective sleeve 22 .
- the interior face of this ring 68 is intended to adhere to the glass base 69 of the body of the syringe 4 to which the needle 6 is fixed, particularly with a view to providing a certain seal against bacteria.
- the protection device 2 is assembled in its retracted configuration, that is to say in its configuration of FIGS. 2 to 7 .
- the protective sleeve 22 is slipped around the support 20 from the distal end of the support, positioning the spring 24 between them. More specifically, the sleeve is moved axially backwards with respect to the support, at the same time radially deforming the hooks 56 outwards using a suitable tool, this being done at least until these hooks axially reach the front part of the longitudinal recesses 26 A.
- the pegs 54 are pressed against the external surfaces 42 B of the tabs 42 , deforming the latter inwards until the pegs are housed in the slot parts 38 .
- the rearwards movement of the protector 22 then continues until the studs 54 are housed in the inclined slot parts 40 , causing the support and the protector to pivot one with respect to the other.
- the protector is thus in the retracted position.
- the end surface forms an end stop able to collaborate with the edge of the recesses 26 A to prevent the protective sleeve 22 from retreating towards the rear end of the support 20 .
- the hooks 56 are therefore in the immobilizing position.
- the glass syringe 1 is prefilled with a liquid to be injected into a patient.
- This syringe is equipped with the cap 66 which grips onto the base 57 of the syringe body 4 .
- the syringe and the cap are inserted inside the assembly 2 to form the injection device, as depicted in FIGS. 6A and 6B . More specifically, the body 4 of the syringe is moved more or less axially within the support 20 . As the body 4 of the syringe engages in the support 20 , and as illustrated in FIG. 6A , the syringe body presses against the inclined rear faces 56 B, thus causing the protrusions of the hooks 56 to become effaced towards the outside.
- the syringe body is moved within the protector until the neck of the syringe 16 , indexed by the projections 34 , clips inside the proximal section 28 , deforming the hooks 32 radially outwards.
- the lugs 18 of the neck of the syringe 16 are then retained axially by the hooks 32 , while the peripheral protrusions 34 restrain the neck of the syringe, and therefore the syringe, in terms of rotation relative to the support 20 .
- the neck of the syringe 16 is completely clipped inside the section 28 , it can no longer fulfill its usual role of forming a bearing surface for the practitioner's index and middle fingers.
- This bearing function is performed by the flange 50 secured to the sleeve 22 .
- the practitioner can then handle the syringe by resting his thumb on the bearing head 14 of the piston 8 , as usual, and resting his index and middle fingers against the faces of the lugs 52 facing towards the needle 6 .
- the practitioner When the practitioner is ready to inject the liquid contained in the syringe, he withdraws the cap 66 by pulling it axially forwards. The ring 68 then moves over the opening 60 , deforming the tabs 58 . Once the cap 66 has been withdrawn, the tabs 58 return to their initial position. The passage hole 60 at the distal end of the sleeve, of a diameter smaller than the outside diameter of the cap 66 , then prevents the cap from being refitted around the needle. The collaboration between the cap 66 and the tabs 58 therefore forms a way of checking that the injection device is indeed being used for the first time.
- the practitioner then withdraws the needle from the patient.
- the practitioner exerts additional pressure on the piston rod 8 .
- This pressure needs to exceed the predetermined force produced by the spring 24 in the locked state so that this spring is compressed further and changes from its length L to a shorter length L′, as depicted in FIGS. 8 to 10 .
- the protective sleeve 24 moves axially towards the proximal end of the support 20 .
- the practitioner performs this movement by exerting corresponding pressure with his index and middle fingers on the lugs 52 of the flange 50 of the sleeve 22 .
- This pressure combined with the translational movement, causes the protective sleeve 22 to rotate about the syringe support 20 , the studs 54 being guided by the inclined slot parts 40 . This rotational movement continues until the studs reach the proximal end of this slot part 40 , that is to say the proximal end of the longitudinal slot part 38 , as visible in FIG. 9 . The device 2 is then in the position in which the spring 24 is unlocked.
- the movement of the needle protector towards the rear end of the support in the spring release direction is rendered possible by the collaboration between the inclined rear faces 56 B of the protrusions of the hooks and the ramps 57 .
- additional outwards deformation of the hooks occurs as illustrated in FIG. 8 .
- the hooks part from one another to pass over the exterior surface of the protective sleeve beyond the recesses 26 A.
- the studs 54 move translationally inside the longitudinal slot part 38 , as far as the distal end thereof as depicted in FIG. 13 .
- the translational movement of the protective sleeve 22 relative to the support 20 can be controlled by the practitioner, if the latter releases gradually the retention that he is exerting with his fingers on the flange 50 .
- the protector is in its deployed position.
- the hooks 56 enter the longitudinal recesses 26 A of the support until they slide along the distal ramps 44 of the support, through the collaboration of their complementary surfaces 56 A and 44 A.
- the hooks 56 are held by collaboration of the surfaces 56 C and 44 B so that the protective sleeve 22 cannot be returned to its initial position.
- the sleeve 22 cannot be readily torn from the support 20 because the studs 54 are in abutment against the distal end of the longitudinal slot part 38 ( FIG. 13 ), the tabs 42 forming this end being held radially between the body of the syringe 1 and the protective sleeve 22 .
- the injection device according to the invention is thus simple to use, while at the same time allowing the practitioner to control the movement whereby the needle is covered by the protective sleeve.
- the number of parts of which the protection assembly 2 depicted is formed is reduced to three.
- the device according to the invention can be fitted to various types of syringe, these varying both in terms of their shape and in terms of their volume. This device therefore has the advantage of not calling into question the overall shape of the syringes used and therefore leads to no modification to the industrial methods used to fill these syringes.
- the studs 54 and/or the flange 50 of the protective sleeve 22 may be attached to the sleeve 22 rather than formed as an integral part thereof;
- the studs 54 may be produced on the external surface of the protector support 20 and the guide slot 36 may be formed in the protective sleeve 22 ;
- the support 20 may be made of one piece with the syringe body 4 ; and/or
- the protrusions 34 of the means 30 for fixing the support 20 on the neck of the syringe 16 may be omitted and possibly replaced by one or more hooks similar to the hooks 32 described hereinabove, all of these hooks axially retaining the neck 16 with respect to the support 20 for any relative angular position of the syringe 1 with respect to support; in this case, the syringe 1 is free to turn inside the support 20 , and this in turn provides greater ease of attachment of the protective assembly 2 to the syringe (absence of indexing).
Abstract
The support device is adapted to be secured to the front face of the injector, and to position an angiographic syringe having a body that presents an outwardly-directed projection, the cross-section of the body at the location of said projection being non-circular. The device which is extended forwards by a cradle for supporting the syringe body, includes an upwardly-open recess that presents firstly a non-circular cross-section that is complementary to a portion of the cross-section of the syringe body at the location of said projection, and secondly an abutment front face for said projection. The recess includes a central portion of circularly-arcuate cross-section, which portion is extended by two diametrically-opposite notches.
Description
- The present invention relates to a needle protection device comprising:
- a protector support delimiting a passage for accepting a syringe body;
- a needle protector able to move with respect to the protector support between a retracted position and a deployed position;
- a compression spring pressing between the protector support and the needle protector; and
- retaining means for initially restraining the needle protector against the action of the compressed spring, which means can be released by moving the needle protector with respect to the protector support in a release direction.
- This needle protection device comprises, in the conventional way, a protector support intended to accept the injection syringe. The protector can move with respect to the support under the action of the spring. Retaining means for initially restraining the protector with respect to the support are provided so as to allow the spring to be released only at the end of injection.
- These retaining means may be released either automatically at the end of injection, or manually.
- When they are being transported, before they are mounted on syringes, the needle protection devices are armed, that is to say that the springs that actuate the protectors are compressed. Thus, should a protection device be vibrated or suffer an impact, the spring may be accidentally released, causing the needle protector to be deployed. The device is then unusable.
- It is an object of the invention to propose a needle protection device in which the risks of accidental triggering when a syringe is not present are reduced.

FIG. 1 depicts, in perspective, a syringe 1 and aprotection assembly 2. In all that which follows, the terms “proximal” and “rear” are synonymous, as are the terms “distal” and “front”. - The syringe 1 is a glass syringe of standard format, intended for single use. It contains a liquid to be injected intramuscularly or subcutaneously into a patient. For this purpose it comprises a body 4, a
needle 6 secured to the distal end of the body 4 and apiston 8. This piston in the conventional way comprises arod 10 provided at its distal end with aplunger 12 visible inFIG. 6A and with a bearinghead 14 against which the thumb of the practitioner's hand is intended to bear. - The body 4 of the syringe comprises, in its proximal part, a
neck 16 circumferentially delimiting two diametrically opposedlugs 18 intended, normally, particularly when theassembly 2 is not present, to form bearing surfaces for the index and middle finger of the practitioner when he or she is handling the syringe and injecting the liquid located therein. - The
protection assembly 2, of overall axis X-X, essentially and as depicted inFIG. 1 , comprises: - a
support 20 of tubular overall shape; - a
protective sleeve 22 arranged coaxially with respect to thesupport 20 and of a diameter greater than that of the support, and - a
spring 24. - These three elements will be detailed in succession hereinbelow with reference to FIGS. 2 to 4.
- The
support 20 comprises a more or less cylindricalmain section 26, having an internal diameter more or less equal to the external diameter of the body 4 of the syringe. Thissection 26 is extended at its proximal end by asecondary section 28 of larger internal and external diameters and those of themain section 26, thereby forming aradial shoulder 29. - The
proximal section 28 is provided withmeans 30 of attachment to the neck of thesyringe 16. More specifically, these means 30 comprise diametrically opposeddeformable hooks 32, also visible inFIG. 1 . Each of these hooks forms a more or lessfrustoconical ramp surface 32A widening towards the free end of thesection 28 which is intended to be pushed back elastically by thelugs 18 of the neck of thesyringe 16 when thesupport 20 is fixed onto the syringe 1. The distance from thehooks 32 to theshoulder 29 is more or less equal to the thickness of thelugs 18. Thehooks 32 thus form a means of clipping onto the neck of thesyringe 16. - Two crook-shaped through-
slots 36 are formed facing one another in themain section 26. Each slot consists of a straightfirst part 38 which runs more or less along the axis X-X of thesupport 20 over a length greater than that of theneedle 6, and of a straightsecond part 40, which runs at an angle to the same axis X-X. Theinclined part 40 opens into the proximal end of the straightfirst part 38, forming a V, the vertex of which points toward the proximal end of theassembly 2. - The
main section 26 at its distal end comprises a first pair of diametrically opposedelastic tabs 42 each one situated in the continuation of the slots 36 (FIG. 5 ). Thesetabs 42 have aninternal face 42A of more or less cylindrical shape and an external face 42B that is more or less frustoconical, widening towards the rear end. - The
main section 26 comprises a pair of diametrically opposedexternal ramps 44 situated between theelastic tabs 42 around the circumference of the distal end of this section. They have a more or less frustoconical inclinedexternal surface 44A diverging towards the front end, and a more less flatdistal surface 44B. Theexternal surfaces 44A thus face towards therecesses 26A. -
Longitudinal recesses 26A are formed in the main section 26 (FIG. 3 ) at the proximal end of theseramps 44. - Furthermore, on either side of the
tabs 42,axial slits 26B are provided originating from the distal end of the support so that before the body 4 of the syringe 1 is inserted in thesupport 20, thesetabs 42 can be deformed radially, particularly inwards. - The
protective sleeve 22 is of a length more or less equal to that of the body 4 of the syringe 1. It consists of twocylindrical sections main section 46 being of a diameter slightly greater than that of themain section 48. These two sections meet to form aradial shoulder 49. - The
sleeve 22 comprises, as an integral part in its proximal part, anexternal flange 50 in the form of two diametrically opposed lugs 52 (FIG. 4 ). - Also in its proximal part, but within the
protective sleeve 22, two diametricallyopposed studs 54 are secured to the sleeve (FIG. 5 ). These two studs are accommodated and guided in the twoslots 36 of thesupport 20 respectively. The support and the sleeve can thus move one relative to the other in terms of translation along their common axis and in terms of limited rotation about the same axis when the studs lie in theinclined parts 40. Theinclined parts 40 therefore form pockets that retain thestuds 54, these pockets having a retention depth denoted p inFIG. 3 . This depth is measured along the axis of the protector. - More specifically, the
support 20 and thesleeve 22 can move between a position in which the sleeve is retracted, in which position most of the sleeve covers most of the support and thestuds 54 lie at the distal end of each of theinclined slot parts 40, as depicted in FIGS. 2 to 7, and a position in which the sleeve is deployed, in which position the sleeve projects axially from the support and the studs lie at the distal end of thestraight slot part 38, as depicted in FIGS. 11 to 13. - When the syringe 1 is fixed on the
assembly 2, these extreme positions correspond respectively to an injection configuration in which theneedle 6 of the syringe 1 is uncovered and intended to be inserted into a patient, and to a protection configuration in which this needle is surrounded by theprotective sleeve 22. - The proximal part of the
sleeve 22 also internally comprises a pair of diametrically opposed deformable longitudinal hooks 56. These hooks are delimited within thesleeve 22 by lateral slits. These hooks are connected to the sleeve at their distal end. Each hook at its proximal free end has an internal protrusion. - When no syringe is present, and as illustrated in
FIG. 3 , the external surfaces of thehooks 56 lie in the continuation of the sleeve. By contrast, the internal protrusions of these hooks project inside the cylindrical passage delimited by thesleeve 22. Each protrusion has afront face 56A of more or less frustoconical shape diverging from the axis of thesleeve 22 towards the front. These front faces 56A thus face the front end of the protector. - Each
front face 56A is designed to collaborate with aninclined surface 44A formed by theramps 44 of the support. - Furthermore, each interior protrusion has an inclined
rear face 56B facing towards the rear end of the protector and, in particular, towards the two lugs 52. Thesesurfaces 56B are generally frustoconical and diverge from one another towards the rear end of the protector. - The
support 20 comprisesfrustoconical ramps 57 arranged to the rear of therecesses 26A. These ramps are inclined towards therecesses 26A and designed to collaborate with the inclined rear faces 56B. - At its free end, each
hook 56 has an inclined transverse surface or 56C forming an end stop. - When there is no syringe present, as illustrated in
FIG. 3 , thesurface 56C of each hook lies immediately facing the corresponding end of therecess 26A. The distance d separating theend face 56C from the edge of the recess is shorter than the depth p of the retention pocket formed of theinclined slot part 40 in which thepeg 54 is held. - When the sleeve is in the retracted position, the
hooks 56 lie inside therecesses 26A formed in thesupport 20. When the sleeve is in the deployed position as depicted inFIG. 11 , the end faces 56C of thehooks 56 are axially in abutment against thetabs 44, the hooks and tabs thereby providing a rigid immobilization assembly in the deployed position. - The
sleeve 22 is also provided at its distal end with a ring ofdeformable tabs 58, the distal edges of which form a more or lesscircular opening 60 of a diameter smaller than the internal diameter of themain section 26 of thesupport 20. - The
spring 24 is a spiral-wound spring, located between theprotective sleeve 22 and theprotector support 20. More specifically, the spring is housed between theshoulder 29 of thesupport 20 and theshoulder 49 of thesleeve 22. When the sleeve is in the retracted position, thespring 24 is in a compressed state, thus having relaxation energy connected with the stiffness of the spring and with the difference between the length of the spring in the state of rest and its length, marked L in FIGS. 2 to 7, in the compressed state. What this amounts to saying is that thespring 24 exhibits an additional compression force threshold which corresponds to the minimum force needed to compress the spring further from its initial compressed state of FIGS. 2 to 7. The spring stiffness and/or the initial compression length L are chosen so that this force threshold is higher than the pressure force needed to move thepiston 8 of the syringe 1 over its entire injection travel. More specifically, the force of the spring in the locked state is greater than the sum of the injection force, that is to say the force needed to expel the liquid from theneedle 6 of the syringe 1, and the forces required to overcome the stiction of theplunger 12 and cause it to slide inside the body 4 of the syringe. - As an option, the
protection assembly 2 further comprises acap 66 of tubular overall shape, depicted inFIGS. 1 and 6 A. - The
cap 66 is designed to surround theneedle 6 before the syringe 1 is used. This cap is closed at one of its ends and its opposite end is formed of anannular ring 68 of an outside diameter tailored to be both a match with thesurface 42A of thehooks 42 of thesupport 20 and greater than the diameter of theopening 60 formed by thetabs 58 of theprotective sleeve 22. The interior face of thisring 68 is intended to adhere to theglass base 69 of the body of the syringe 4 to which theneedle 6 is fixed, particularly with a view to providing a certain seal against bacteria. - The way in which the injection device according to the invention works is as follows:
- The
protection device 2 is assembled in its retracted configuration, that is to say in its configuration of FIGS. 2 to 7. To do that, theprotective sleeve 22 is slipped around thesupport 20 from the distal end of the support, positioning thespring 24 between them. More specifically, the sleeve is moved axially backwards with respect to the support, at the same time radially deforming thehooks 56 outwards using a suitable tool, this being done at least until these hooks axially reach the front part of thelongitudinal recesses 26A. Next, still moving the sleeve backwards, thepegs 54 are pressed against the external surfaces 42B of thetabs 42, deforming the latter inwards until the pegs are housed in theslot parts 38. The rearwards movement of theprotector 22 then continues until thestuds 54 are housed in theinclined slot parts 40, causing the support and the protector to pivot one with respect to the other. The protector is thus in the retracted position. - In this position and as illustrated in
FIG. 3 , the internal protrusions of thehooks 56 project into the passage for accepting the syringe so that the reartransverse surface 56C lies immediately in front of the corresponding edge of therecess 26A. - The end surface forms an end stop able to collaborate with the edge of the
recesses 26A to prevent theprotective sleeve 22 from retreating towards the rear end of thesupport 20. Thehooks 56 are therefore in the immobilizing position. - As will be explained later on, in as much as the retention of the spring that moves the protective sleeve is released by moving the protector rearwards, any risk of accidental triggering of the protective sleeve while the protective device is being transported is avoided because the protective sleeve is immobilized in its release direction independently of the spring retention means, as long as no syringe has been introduced into the protector support.
- The glass syringe 1 is prefilled with a liquid to be injected into a patient. This syringe is equipped with the
cap 66 which grips onto thebase 57 of the syringe body 4. - The syringe and the cap are inserted inside the
assembly 2 to form the injection device, as depicted inFIGS. 6A and 6B . More specifically, the body 4 of the syringe is moved more or less axially within thesupport 20. As the body 4 of the syringe engages in thesupport 20, and as illustrated inFIG. 6A , the syringe body presses against the inclined rear faces 56B, thus causing the protrusions of thehooks 56 to become effaced towards the outside. - In particular, the end faces 56C of the hooks and the corresponding edges of the
recesses 26A are misaligned. The hooks are therefore in the mobilizing position. - The syringe body is moved within the protector until the neck of the
syringe 16, indexed by the projections 34, clips inside theproximal section 28, deforming thehooks 32 radially outwards. Thelugs 18 of the neck of thesyringe 16 are then retained axially by thehooks 32, while the peripheral protrusions 34 restrain the neck of the syringe, and therefore the syringe, in terms of rotation relative to thesupport 20. - In addition, in as much as the neck of the
syringe 16 is completely clipped inside thesection 28, it can no longer fulfill its usual role of forming a bearing surface for the practitioner's index and middle fingers. This bearing function is performed by theflange 50 secured to thesleeve 22. Specifically, in as much as the length of theprotective sleeve 22 is more or less equal to that of the syringe body 4 and/or in as much as theflange 50 is formed at the proximal end of this sleeve, the practitioner can then handle the syringe by resting his thumb on the bearinghead 14 of thepiston 8, as usual, and resting his index and middle fingers against the faces of thelugs 52 facing towards theneedle 6. - Furthermore, when the syringe 1 is fixed on the
protector support 20 as depicted inFIGS. 6A and 6B , thecap 66 projects out from theprotective sleeve 22. - When the practitioner is ready to inject the liquid contained in the syringe, he withdraws the
cap 66 by pulling it axially forwards. Thering 68 then moves over theopening 60, deforming thetabs 58. Once thecap 66 has been withdrawn, thetabs 58 return to their initial position. Thepassage hole 60 at the distal end of the sleeve, of a diameter smaller than the outside diameter of thecap 66, then prevents the cap from being refitted around the needle. The collaboration between thecap 66 and thetabs 58 therefore forms a way of checking that the injection device is indeed being used for the first time. - The practitioner then pierces the patient's skin with the
needle 6. He injects the liquid contained in the syringe by pressing against the bearinghead 14 of thepiston 8, his index and middle fingers remaining in contact with the faces of thelugs 52 that face towards the needle. During injection, there is no movement between theprotector support 20 and theprotective sleeve 22, thespring 24 remaining compressed at a length L, as depicted inFIG. 7 . - Injection continues until the
plunger 12 of thepiston 8 reaches the end of the injection travel. - The practitioner then withdraws the needle from the patient. In order to trigger the
protection assembly 2, the practitioner exerts additional pressure on thepiston rod 8. This pressure needs to exceed the predetermined force produced by thespring 24 in the locked state so that this spring is compressed further and changes from its length L to a shorter length L′, as depicted in FIGS. 8 to 10. To do this, on the assumption that the syringe support does not move, theprotective sleeve 24 moves axially towards the proximal end of thesupport 20. The practitioner performs this movement by exerting corresponding pressure with his index and middle fingers on thelugs 52 of theflange 50 of thesleeve 22. This pressure, combined with the translational movement, causes theprotective sleeve 22 to rotate about thesyringe support 20, thestuds 54 being guided by theinclined slot parts 40. This rotational movement continues until the studs reach the proximal end of thisslot part 40, that is to say the proximal end of thelongitudinal slot part 38, as visible inFIG. 9 . Thedevice 2 is then in the position in which thespring 24 is unlocked. - The movement of the needle protector towards the rear end of the support in the spring release direction is rendered possible by the collaboration between the inclined rear faces 56B of the protrusions of the hooks and the
ramps 57. During the movement of the protector, additional outwards deformation of the hooks occurs as illustrated inFIG. 8 . Thus, the hooks part from one another to pass over the exterior surface of the protective sleeve beyond therecesses 26A. - The practitioner then releases the pressure he was hitherto exerting on the
flange 50, allowing thespring 24 to relax to a state of rest. Thestuds 54 move translationally inside thelongitudinal slot part 38, as far as the distal end thereof as depicted inFIG. 13 . The translational movement of theprotective sleeve 22 relative to thesupport 20 can be controlled by the practitioner, if the latter releases gradually the retention that he is exerting with his fingers on theflange 50. When thestuds 54 have reached the distal end of the slot 36 (FIG. 13 ) the protector is in its deployed position. - Furthermore, when the
protective sleeve 22 is in translational movement relative to thesupport 20, thehooks 56 enter thelongitudinal recesses 26A of the support until they slide along thedistal ramps 44 of the support, through the collaboration of theircomplementary surfaces - When the protector is in the deployed position, the
hooks 56 are held by collaboration of thesurfaces protective sleeve 22 cannot be returned to its initial position. Likewise, thesleeve 22 cannot be readily torn from thesupport 20 because thestuds 54 are in abutment against the distal end of the longitudinal slot part 38 (FIG. 13 ), thetabs 42 forming this end being held radially between the body of the syringe 1 and theprotective sleeve 22. - The injection device according to the invention is thus simple to use, while at the same time allowing the practitioner to control the movement whereby the needle is covered by the protective sleeve. The number of parts of which the
protection assembly 2 depicted is formed is reduced to three. - The device according to the invention can be fitted to various types of syringe, these varying both in terms of their shape and in terms of their volume. This device therefore has the advantage of not calling into question the overall shape of the syringes used and therefore leads to no modification to the industrial methods used to fill these syringes.
- Various variants of the device according to the invention are conceivable:
- unlike in the exemplary embodiment described hereinabove, the
studs 54 and/or theflange 50 of theprotective sleeve 22 may be attached to thesleeve 22 rather than formed as an integral part thereof; - as the inverse of the device described, the
studs 54 may be produced on the external surface of theprotector support 20 and theguide slot 36 may be formed in theprotective sleeve 22; - the
support 20 may be made of one piece with the syringe body 4; and/or - the protrusions 34 of the
means 30 for fixing thesupport 20 on the neck of thesyringe 16 may be omitted and possibly replaced by one or more hooks similar to thehooks 32 described hereinabove, all of these hooks axially retaining theneck 16 with respect to thesupport 20 for any relative angular position of the syringe 1 with respect to support; in this case, the syringe 1 is free to turn inside thesupport 20, and this in turn provides greater ease of attachment of theprotective assembly 2 to the syringe (absence of indexing).
