I-:NGE HY PODERMIC MEDICATION rl Melton, Louisvill FOR yUse kWITH CARTRIDGES e, Kyi, assigner of onen Newbur'g'e, Hamilton Harold M. Baron, administrator of said Lessing B. Newburger, deceased Appueatin september so, 1947,
lThis invention relates to comprising a syringe and a therefore, and the parts a nypoermic unit, medication cartridge kdonnarising the unit which are separate articles of 'manufacture and sale but are readily assembled together for use. A hypodermic needlei's` assembled with the medication cartridge and hernietically sealed to be placed in sealed condition in the syringe with and as part of the Vmedication cartridge. The needle is hermetically sealed by a protective sheath of any suitable material which facilitates insertion of the cartridge in the syringe and is not removed until after assembly or insertion of the cartridge in the syringe.
The invention not oniy comprises a unit which is simple in construction and assembly and eiiicient in operation, but the medication car-- tridge unit is prepared ready for use by sirnply inserting saine in the barrel of the syringe and then removing the needleproteetive she'at- The needle is included -with the medication car tridg'e and is hei'neti'eally sealed with the sheath which facilitates insertion of th'cartridge in the syringe and is not removed until the syringe is loadethf Thus; both the syringe and cartridge may be handled without contaminating the needle. The cartridge, including the needle, is
of after application or' use or" the inedication, thereby also avoiding contamination resulting from improper sterilization where the Sarre needle is used repeatedly for applying more than one medication; The tiine and trouble for sterilization of the needle for each application is avoided. Each cartridge` is Hcomplete with meditation and needle and with the needle iuily protected for being handled without contamination. y Y
The syringe comprises a barrelv hinged to a holder for a plunger handle so that a cartridge may be readily inserted in and removed from the sheath or barrel when the syringeri's breeched by means of the hinged connection between the barrel and the plunger handle holder. Abut= ment lmeans isprovidecl on the barrel to engage a portion of the cartridge as the cartridge is spring pressed in the barrel by rneans on the head of the syringe. Finger holders vare disposed oppositely onk the plunger handle holder so that' the syringe :nay be readily grasped for manipulation of the plunger handle to move the piston in the cartridge as hereinafter described.
The cartridge has a transparent hollow tube with a needle mounted in oneeend-and a piston mounted` in the opposite end adjacent to the end of the plunger of' the syringe. A medication is 55 'serial No. 776.908
(Cl. 12K-218) The exposed end of the needle is covered with a shield or protector having an open end, opposite a closed en d, to iit on a proiection which will herinetically seal the shield or protector for the needle.
of the cartridge. Selective manipulation of the piston forward orbackward by the user is i'rnportant in determining whether the needle has or has not penetrated a vein of the patient, for the user must positively know that a vein has been penetrateduif an intravenous injection isl to be given or that a vein has not `been penetrated if it is an intrainusel'ar injection.
For a better understanding of the invention, reference is made to the accompanying drawings, in which:
Fig. 1 is a longitudinal cross-seaman view of' an embodiment of the invention;
Fig'. 2 is a View showing the syringe being breeched for insertion of the cartridge;
Fig'. 3 is a cross-section on lines 3-3 of Fig. 1; and
Fig. 4 is a longitudinal eress-sctionai view of the medication cartridge unit'.
Referring specicany to the drawigsin which like numerals areV used to designate like parts, numeral 2 designates generally the syringe which is composed of a tubular barrel 3 and the handle holder 4 pivoted at 5.
The' barrel 3 may be of' any material, 'preferably of non-corrosive metal, with openings 6 in opposite sides. Ane end of the barrel 1s provided with an inwardly extending ange or lug 1, preferably annular and also preferably integrally formed. The opposite end of the barrel is eben and unobstructed, and preferably has portions of the side edges out away at 8 to be out of contact with the end of pressed member in after described.
The handle holder is hollow to provide a chamber l between one end having an inwardly extending flange Il and the opposite end having an outwardly extending flange l2, the outer peripheral edge being knurled at I3. A ring I4, having oppositely disposed arms l5, is loosely mounted upon the outer wall of the handle holder adjacent the flange l2 and confined by a nange IS. The spaced-apart flanges form a groove therebetween within which the ring is loosely held so that it can be turned relatively to the handle holder.
A cylindrical bushing ll is fitted to slide within the chamber and has a diameter slightly less than the diameter of the bore of the cartridge tube so that the end of the bushing will iit within the end of the bore in the hollow tube of the cartridge. The bushing is spring pressed by a spring I8 which normally holds the end of the bushing in the end of the barrel 3 to axially aline same with the handle 9 which manipulates the hereinafter described piston of the cartridge. The end of the bushing also abuts against the vcartridge Aand holds same tightly within the Syringe.
The handle has a plunger handle 9 or a spring the handle holder hereindetachable knob i9 on one end and a collar 2E! on its opposite end. The collar has a screw-threaded socket 2l to be screwthreadedly engaged with a stub shaft 22 which is anchored to the hereinafter described piston of the cartridge. The handle is freely reciprocable in the holder, and the collar to engage a shoulder 23 on the bushing whereby the end of the bushing may be withdrawn from the barrel of the syringe, against the compression of the spring, when the handle is retracted to its extreme position. A recess 23a may be formed advantageously in the end of the bushing to receive the collar Zll when same is retracted. Thus, the end of the handle will clear the end of the barrel of the syringe when the syringe is breeched.
The cartridge comprises a tube 24, of any transparent material, such as glass or plastic, having a hypodermic needle 25 mounted in one end. This may be done conveniently by a resilient stopper 26, such as rubber, preferably having a portion 26a fitting into the end of the tube and provided with a head portion 251). rlChe head portion, if there be any head portion on the stopper, abuts against the end of the tube 2li. The stopper could be formed without any head portion, but the head is preferable to protect the end of the tube and provide a cushion between it and ange ll. A hub projection 21 is mounted on the needle and provided with a reduced portion 28 to project and tightly fit into the open end of a protective sheath 29 for hermetically sealing the needle. This protective sheath may be of any suitable material, such as glass, plastics, or the like, and preferably transparent. The opposite end of the protective sheath is closed. The hub projection 2l may be of metal, rubber, plastic or any suitable material which will make a tight fit with the sheath. There is also a head ao which may be a part of or separate from the hub. This head is of sufficiently large diameter to seat upon the lug or flange 1 of the syringe barrel and is secured fast to the needle so that the needle cannot be pulled out of its mounting 26. The head may be of any material but is preferably of rubber, and more especially if the stopper 26 is not provided with an 2@ thereof is adapted 4 enlarged head 2Gb, to serve as a gasket together with or without the enlarged head of the stopper 25 between the lug and flange 'i and the end of the tube 24 of the cartridge. These resilient parts, or either of them, allow for any tolerance so that the cartridge can be tightly iitting.
A piston 36 is fitted into the opposite end of the tube 24 and has the stub shaft 22, screwthreaded on the exposed end, projecting from one end. A medication is placed in the tube of the lcartridge between the piston and the stopper or needle mounting.
The cartridge comes all prepared with the medication ready for use and needs only to be inserted in the syringe and the guard sheath removed just before use. The handle of the syringe is then forced forward and turned to engage the piston. The medication may be one to be used intramuscularly or intravenously, and the handle is constructed to be turned to screw-threadedly engage it with the stub shaft on the piston, thereby permitting the piston to be retracted as well as pushed in. A slight retraction of the piston, after insertion of the needle, will disclose whether a blood vessel has been penetrated, for, if it has, blood will show in the medication through the transparent sheath. Thus, an intramuscular or intravenous injection can be positively made.
The unit permits complete sterile technique for hypodermic injections of any material and eliminates the time and trouble for preparing keeping the syringe sterile. Only one syringe needs to be carried by a doctor, which syringe be used repeatedly regardless of the medication involved. Different cartridges have different types of medication, any of which could be selected for use with the single syringe. A used cartridge is disposed of after use, and a new one is inserted. Thus, there is no possibility for contamination. The cartridges may be labeled for identication as to the medication, and the proper ones may be selected for loading into the syringe for application.
The needle is not only combined with the medication cartridge but a sheath therefor is employed to protect the needle and facilitate insertion of the cartridge within the syringe. The medication, needle and shield comprise the cartridge unit which is assembled with the needle hermetically sealed, the needle shield not being removed until the hypodermic injection is to be given.
The hypodermic medicating unit or cartridge is the subject of a divisional application.
While the invention has been described in detail, it will be understood that there may be changes in details of construction without departing from the spirit of the invention as defined in the appended claims.
