VESTJOGKET HYPODERMIC-SYRINGE' CONTAINER.

Application filed April 5, 1929. Serial No. 352,704;

This invention relates to containers or casings for hypodermic syringes. r.

A container for a hypodermic syringe should fulfill a number of requirements, 5 which are occasioned both by the nature of the hypodermic syringe itself and by the use to which itis put. Hypodermic syrlnges as ordinarily on the market are made wlth aglass barrel, a glass plungerand a metal tip detachable from the barrel. Both the glass parts and the metal tip are easily broken, and it is necessary, thereforeythat 1n carryingthem they be protectedtrom injury. Hypodcrmic syringes are, of course, used to administer various drugs directly into the body, audit is of prime importance that they be strictly sterile. Ordinarily this sterility is secured by boiling the syringe or1mmersing it*in alcohol or other antiseptic soliitioniinniecliatcly previous to the time it is used.

Inasmuch asuthe hypodermic syringe has become one ofthe most essential instruments in emergency cases, it is important that some means be provided for carrying the syringe in asaife, sterile and convenientmanner. It is important that it be carried conveniently in order that the doctor may have it wlth him at all times. It is important, moreover, that the doctor; have with him not only the syringe but the necessary drugs, and any container for thesyringe should therefore provide some meansof holding the necessary drugs separate and apart from the syringe.

So far as I am aware, there has never been a container for a hypodermic syringe that combines these qualities. Somecontainers which have been proposed are bulky and not adapted to be conveniently carried at all times; others are mere carrying cases which do notkeep the syringe sterile others which domaintain the syringe partsterile contain antiseptic fluids which are likely to spill andmake the use of the syringe inconvenient, and at times even u-nsterile.

The object of this invention, therefore, is toprovidc a compact form ofcontainer for a hypodermic syringe and the drugs to be used therewith which will protect the syringe and preventit from brealmge while itis being carried, which will maintain it at all times sterile and yet ready for instant use without destroying the sterility, and

which is of a size and-shape that it may be conveniently carried in a vestpocket in the manner ofatountain pen so thatit may be carried at all times;

I accomplish this objcctby providing a rigid containerhavingthree compartmentsone for the needletip, one for the glass barrel and plunger, and the other for the drugs-and shaped substantially like" a foun-L tain pen. The compartment containing the tip may be especially shaped toretainfthe tip, but isdesigned to be attached to the compartment containing the barrel and plunger so that an airtight oint is .formed. This end is, of course, preferably accomplished by merelyscrewing'the two parts together; The compartment containingthe drugs-is also preferablyattached at the other end of the compartment containing the bar relandplunger'by a screw threadforming an airtightjoint. l

The syringe is h el'd disassembled in two compartinents rather than assemblednin one compartment, because this facilitates its use withoutlilreliheod of contamination. By the construction which I provide", thezsyringe barrelmay be attached to the needle tip, which is held in its propercompartment all without ever touching the" needle tip..

The permanentsterility of the syringe is maintained by the airtight joint, which con nects the twocompartments containingythe syringe parts. When the syringe andcontainer areonce sterilized in the doctors office and the syringe is placedlund'er sterile conditio-ns-within the compartments of'th'e container' and thetwo compartments locked togetheiythe syringe willhe maintained in a sterile condition for an indefinite period of time.

An embodiment ofmy invention is shown, by way of example, in the drawing, in which Fig." 1 re n'esents a sectional elevation: of thecontainer showingthe positions of the needle, the syringe b'arrcl and the vials for the dru 's line 44 of Fig. 1, showing the cells for storing the drug vials;

' the main body portion 11 is sealed by a cap 12, which is adapted to receive and retain the hypodermic needle 14. The needle 14 is held in the cap 12 by means of the shoulders 17 formed in the cap and clearly shown in Figs. 1 and 3. The hollow member 13 is attached in a convenient manner to the closed end of the main body portion 11. The member 13 is provided with cells or compartments 18, as shown in Figs. 1 and t 4. The cells 18 are adapted to receive the drug vials which contain the drugs to be used wlth the hypoderm1c syringe. In case it Is desired to use drugs which are prepared .in the form of tablets or in any other form.

an. alternative form of hollow member 19, shown in Fig. 5, may be substituted for the member 13.

The container is composed of any suitable material, such as aluminum, bakelite,

rd rubber, etc., which will permit of an effective seal between the barrel 11 and its closure cap 12. There should be a lock joint between the cap 12 and the barrel 11, and this may be effected by a screw thread joint 20, as shown in the drawing, or any other suitable means. I 1

In preparing the container for use, the barrel 11, cap 12, hypodermic needle and barrel. are sterilized, for instance by boiling in water. The hypodermic needle 14 is inserted in the cap 12 by means of some sterilized instrument, and is turned so that the lower end of the needle will engage the shoulders 17 and be retained in the cap thereby. The, syringe barrel 15 is then placed in the main body portion or barrel .11 with the-nipple 21, atvthe bottom of the barrel 11. The cap 14 is then screwed into the barrel 11, thus sealing the container. The hypodermic needle and barrel thus 5 5 sealedare kept indefinitely in a sterile condition and can be used after long periods with .out danger. of infection.v

The drug vials 16 are placed in the member 13, or the drug tablets or solution are placed in the member 19, and one or the other isconnected to the closed end of the barrelll.

The container 10 is now completely assem bled and contains all the necessary equipment for a hypodermic injection in an aseptic condition. The container 1s small and compact and may be easily carried in a vest pocket.

In service when it is desired to use the hypodermic syringe, the cap 12 is unscrewed from the barrel 11. As the needle is held in the cap 12 by the shoulders 17. no particular care is needed in this operation. The syringe barrel 15 is then removed from the barrel 11 and the nipple 21 on the syringe barrel 15 is inserted into the lower end of the needle 14, which is still in the cap 12. The needle 14 is then turned by rotating the syringe barrel 15, thus disengaging the lower end of the needle 14 from the shoulders 17 and permitting the removal of the cap 12.

The hypodermic syringe is now assembled and is filled with the drugs contained in member 13 or 19, as the case may be by removing the plunger 22 from the syringe barrel 15 and pouring the liquid drug therein. The plunger 22 is then replaced and the syringe is ready for use.

In assembling the syringe, neither the needle 14 nor the nipple 21 is touched by hands or instruments, thus eliminating all danger of contamination or infection.

I claim:

1. In a hypodermic syringe container adapted to protect a syringe from breakage, maintain it in a sterile condition and serve as a holder for the needle to permit convenient assembly of the syringe without contamination of the syringe, comprising an open-ended receptacle for the syringe barrel, a closure member for said receptacle adapted to receive the hypodermic needle, and means within said closure member for retaining the hypodermic needle within said member.

2. A hypodermic syringe container adapted to protect a syringe from breakage, maintain it in a sterile condition and serve as a holder for the needle to permit convenient assembly of the syringe without contamination of the syringe, comprising an openended receptacle for the syringe barrel, a closure member for said receptacle adapted to receive the hypodermic needle, and means within said closure member for retaining the hypodermic needle within said member, said receptacle and closure member being provided with means for forming an airtight seal.

3. A hypodermic syringe container adapted to protect a syringe from breakage, malntain it in a sterile condition and serve as a holder for the needle to permit convenient assembly of the syringe without contamination of the syringe, comprising a closed tube separable intermediate its extremities, one of the separable portions of said tube having a cavity formed approximately to the shape of the syringe barrel, the other of the separable portions having a cavity formed approximately to the shape of the syringe needle, and means on the separable portion adapted to receive the syringe needle for retaining the syringe needle Within said portion.

4. A hypodermic syringe container comprising a closed tube separable intermediate its extremities, each separable portion of said tube being formed of one piece, said separable portions having cavities respectively formed approximately to the shape of the syringe barrel and the syringe needle, said cavities decreasing progressively in diameter from the point of separation of said separable portions to prevent the syringe parts from being inserted into said cavities except in the manner desired and to render said cavities more accessible for cleaning, and means on said separable portions adapted to form an airtight seal between said separable portions, the separable portion formed ap proximately to the shape of the syringe needle being constructed to effect a maintenance of the needle so that the barrel may be attached to the needle before the needle is removed from said portion.

In testimony whereof I aflix my signature.
