PAIENIED lanes m4 METER L'W [I0 INVENTOR RICHA ATT R N EYS ANALGESIC APPARATUS ister analgesic gases, such as, nitrous oxide to a patient through a nasal inhalator in order to reduce .the pa-v I tients sensibility to pain without making him unconscious and while leaving the mouth free and unobstructed for dental or surgical work. Conventionally, the nasal inhalator is cupped over the patients nose and can be firmly seated on the patients face in the region surrounding the nose. Typically when the patient is in a prone position, gas is supplied to the inhalator through hoses which lead directly over the chair and face of the patient into the inhalator or may hang downwardly along the sides of the patient and chair then lead into the gas supply source. As a result, the gas supply hoses tend to interfere with the dentist in his work, making it difficult to keep the inhalator properly positioned and stabilized over the nose and also limit movement of the patients head.
Accordingly, it is an object of the present invention to provide for a novel and improved gas delivery device for use in supplying analgesic gases or anesthetic to a nasal inhalator or face mask in dental or surgical operations.
- It is another object of the present invention to provide for a novel and improved gas delivery device for use in supplying analgesic gases or anesthetic to a nasal inhalator or face mask in dental or surgical operations.
It is another object of the present invention to provide for novel and improved gas delivery apparatus for use in analgesic systems wherein the gases are supplied through lines passing over the top and along the sides of the patients head so as not to limit head movement and not to present an obstruction to the dentist or surgeon in his work.
It is another object of the present invention to provide for gas delivery apparatus for use in an analgesic system in which triangulated gas supply hoses extend between a metered gas supply and the sides of an inhalator in such a way that the gas supply lines are directed downwardly along the sides of the face and rearwardly over the top or crown of the patients head when the patient is in a prone position.
It is a further object of the present invention to provide for a novel and improved hose-linkage device specifically adapted for use in administering gas from a gas supply source to a nasal inhalator which includes a triangulated gas supply hose assembly between a metered gas supply and the inhalator, the hose assembly being adjustably and releasably secured to the patients head without discomfort and permitting greater freedom of movement of the head without obstructing or interfering with the dental or surgical procedures.
The present invention is best exemplified by describing its use in connection with dental work wherein it is becoming more customary to administer analgesic gas through a nasal inhalator. It is standard practice to place the patient in a prone position in the dental chair and with the end of the chair supporting the patients head in proximity to a metered source of gas supply. In accordance with the present invention, a pair ofgas delivery lines extend between the metered source of gas supply and the nasal inhalator and include lateral extensions which extend for relatively short distances in opposite directions away from opposite sides of the nasal inhalator to terminate at a point on opposite sides of the patients head near the ears where theyv are joined by elbow-shaped fittings to rearwardly directed extension hoses leading rearwardly from the sides over the top or crown of the patients head into the metered gas supply source. A hose clip is movable along the length of the rearward extension hoses to secure the hoses together at a location near the crown of the patients head and, together with a connecting strap which is passed from the elbow portion of the hoses behind the neck, defines a fixed triangulation arrangement between the hose sections so as to firmly stabilize the inhalator over the nose and permit greater freedom of movement of the patients head. In addition, since the extension hoses lead away from the lower ends of the extension hoses directly over the end of the chair to the metered gas supply source they do not present an obstruction or interfere with the dentist in his work. Moreover, in a manner to be hereinafter appreciated in more detail the assembly is readily conformable for use in different applications, and further can be readily adjusted and securely attached to the patients head.
The foregoing and other objects, advantages and features of the present invention will become more readily appreciated and understood from the following more particular description of the invention when taken in conjunction with the accompanying drawings, in which:
FIG. 1 is an isometric view of the hose-linkage device of the present invention in operable use on a patient in an analgesic system.
FIG. 2 is an enlarged isometric view of the hoselinkage device of FIG. 1 attached to a conventional nose piece and also showing an anchoring strap for holding the nose piece against a patients face.
FIG. 3 is an enlarged plan view of the elbow joint used in the hose-linkage device of FIG. 1.
DESCRIPTION OF A PREFERRED EMBODIMENT Referring first to FIG. 1, an analgesic system is shown having a metered source 10 of analgesic gas, such as nitrous oxide, connected to a conventional inhalator or nose piece 12 by a preferred form of gas delivery apparatus 14 of the present invention.
The inhalator 12, best seen in FIG. 2, is a flexible rubber cup adapted to fit'down over the nose of a patient P and seat on the patients face, as shown in FIG. 1. The nose piece has an adjustable valve 15 to regulate the amount of air mixed with the analgesic gas administered to the patient, and suitable gas inlet means including two protruding hollow arms 16 and 18 extending from opposite sides of the inhalator which have rigid tubular hose connectors 20 and 22, respectively, hermetically sealed in their ends.
The gas delivery apparatus 14 takes the form of a hose-linkage device which includes a pair of gas supply conduits leading into opposite sides of the inhalator and consist of identical flexible rubber lateral extension hoses 24 and 26, a pair of identical hollow elbow joints cent the top of a patients head.
The lateral extension hoses 24 and 26 of the hoselinkage device comprise short pieces of flexible rubber hose (approximately two inches in length) which fit tightly at one end in an hermetic seal on the protruding ends of the hose connectors 20 and 22 respectively.
Elbow joint 28, which as stated before is identical to elbow joint 30, can be seen in FIG. 3 to have'identical annular recessed ends 38 and 40. The recessed end 38 of each of the elbow joints 28 and 30 is adapted to be inserted into the free end of the extension hoses 24 and 26 respectively to provide hermetically sealed connections therewith. In practice the end 38 of each of the elbow joints would be inserted into the respective extension hoses so that the recessed end 40 of each of the elbow joints would be pointed toward the top of the patients head.
The recessed end 40 of each of the elbow joints 28 and 30 is adapted to be inserted into one end of the gas supply hoses 32 and 34 respectively to provide hermetically sealed connections therewith. The other end of each of the gas supply hoses 32 and 34 is attached to a Y-fitting 42 which is connected in fluid communication to the metered gas source 10. Accordingly, two hermetically sealed fluid passages are provided through the hose-linkage device 14, whereby analgesic gas can be passed from the metered gas source to the inhalator 12.
The hose clip 36 of the hose-linkage device is comprised of a flat bar having two adjacent apertures therethrough and, as stated before, serves to hold the two gas supply hoses 32 and 34 together at a location adjacent the patients head. The diameter of each of the apertures in the flat bar is substantially equivalent to the outside diameter of each of the gas supply hoses so that the clip 36 can be manually slid along the length of the hoses and will retain its longitudinal position on the hoses when released.
It will be apparent that the clip 36 when positioned adjacent the top of a patients head and the elbow joints 28 and 30 define corners of a triangle whose respective sides are comprised of a portion of the supply hose 32, a portion of the supply hose 34, and the inhalator 12 along with the tubular connectors and 22 and the extension hoses 24 and 26. This triangular arrangement provides a three-point stabilizing system for the inhalator 12 to prevent it from being easily dislocated since the elbow joints 28 and rest on the cheeks of the patient on either side of the nose, and the hose clip 36 rests near the top of the patients head at a location approximately equispaced from the two elbow joints.
To further stabilize the nose piece 12 on the patients head and also to help provide an effective seal between the nose piece and the face of the patient to prevent peripheral leakage of the analgesic gas, connecting strap means 44, which can be passed behind the patients head, are attached to the hose-linkage device 14. The anchoring strap means consists of a flat band having one end 50 looped over and attached to elbow joint 28, for example, by a rivet 51 attaching the free end to the band as shown. The opposite end 52 is adjustably attached to a connecting ring 53 surrounding a portion of the elbow 28. In order to effect an adjustable but secure, releasable attachment of the end 52 to the ring 53, both are surfaced with velcro tape fastening means 46 so that they can be quickly and easily secured together with the free end passing around the inside of the ring between the hose assembly and the side of the patients head. Also, an elastic section 56 is provided in an intermediate portion of the band to assure a firm but yieldable attachment of the strap behind the patients neck. Alternately, instead of attaching the free end 52 to the inside of the ring 53 as shown, it may be secured to the outside of the ring and a separate tape fastening strip attached to the inside in order to cover that portion of the ring 53 not secured to the free end 52 and prevent the ring from rubbing directly against the side of the patients face.
It can thus be appreciated that a device for stabilizing an inhalator on a patent has been provided which includes means for fluidically connecting the inhalator to a gas supply and means for positioning the inhalator against the patients face to alleviate peripheral leakage around the inhalator. The device is also effective in directing the gas supply hoses over the top of the patients head where they will not interfere with a dentists legs when he is working on the patient and will not inhibit head movement of the patient.
Although the best mode contemplated for carrying out the present invention has been herein shown and described, it will be apparent that modification and variation may be made without departing from what is regarded to be the subject matter of the invention.
