HYPODERMIC SYRINGE Filed April 26, 1924 fnvej z 011 Patented Aug. 4, 1931 UNITED STATES PATENT OFFICE GEORGE N. HEIN, F SAN FRANCISCO, CALIFORNIA HYPODERMIC sYnINGE nppneauon med April 2e, 1924. serial No. 709,152.

to be applied is deposited. To eject the fluid a piston is employed and the same is inserted into'l the barrel through its open end. In someI cases, first charges of material such as cartridges, medically termed ampules, are inserted in the barrel and the contents thereof is, on the movement of the piston discharged through the needle.

The present invention relates broadly to what may be termed a two-part syringe, one part constituting a tubular piston mounting the needle and the hand grip and the other constituting an ampule or cartridge serving as a barrel and having telescopic movement over the piston in the discharge of its contents.

In addition to the objects set forth in the immediately preceding paragraph, the invention has for another object to provide an improved form of ampule having a puncturable closure serving as an expelling piston head; another object is the'incorporationvin the piston of a means for puncturing the ampule the same to be maintained sealed until that time when it is desired to expel the contents therefrom; another object is to provide in connectionl with the piston,

when necessary, a barrel for receiving the material to be applied through the syringe by the material being directly deposited therein or received therein by the depositin of the sealed ampule.`

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scopeof the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Fig. 1 is a view in longitudinal section of yby the use of a hypodermic syringe.

one embodiment of my invention with the ampule serving as the applying barrel.

Fig. 2 is a view in longitudinal section of the needle base mounting the ampule puncturing needle and the hypodermic needle.

Fig. 3 is a longitudinal sectional view of a modified form of construction and Fig. 4 is a view in elevation of the construction illustrated in Fig. 3.

Figure 5 is a longitudinal sectional view of a holder showing an ampule placed therein anda portion of the piston structure.

Inthe drawings, the numeral 1 indicates the elongated shell of any suitable material preferably circular in cross section closed at one end as at 2 and open at its opposite end as at 3, the same forming an ampule for containing a charge of liquid 4 to be ap lied Xfter the fluid has been deposited in. the ampule the open end 3 thereof is closed by a member 5 of any suitable puncturable material such as cork or rubber. The member 5 is adapted for reciprocating movement within the ampule .with its peripheral edge lin tight frictional contact with the inner Wall of the ampuleA and. thereby serving as an expelling piston or washer. The center of the ampule is relatively thin as at 6 for the hereinafter described purpose.

The numeral 7 indicates a piston having a tubular open ended bore 8 extending longitudinally thereof, one end of said bore having inserted thereinto a demountable needle base 9 havin threaded' engagement therewith. A tubu ar needle 10 is provided preferably extending longitudinally of the piston 8 to a point to project beyond the end thereof as in Fig. 1. A detachable needle is thereby provided so it may be readily sterilized or may be changed for diii'erent patients or at will. The puncturing point of the needle 10 extends through an opening in the piston head 1l detachably secured to the end of the piston 7 and closing the boreY 8 thereof. As illustrated, the puncturing point of the needle 10 projects a suiiicient distance beyondthe end wall of the piston head to pass through the Wall 6 of the lclosure 5 on pressure being applied to the ampule 2 I end and by an operator endeavoring to force the ampule over the piston as hereinafter described. Extending outwardly from the base 9 and communicating with the needle.

10 is a conventional hypodermic needle 12.

To enable the operator to grasp the piston, a suitable member 13 is detachablyI threaded as at 14 or otherwise secured to the end of the piston 7 and the same carries linger grip portions 15.

`When in use the device described operates in the following manner.

The operator takes the sealed ampule and fits the same over the piston head 11, en-

gages the fingers under the members 15 and applies the pressure of the thumb to the end 2 of the ampule. This application of pressure causes the end of the needle 10 to puncture the closure 5 and provide an outlet for the contents of the ampule through needle 10 and through needle 12. The continued application of pressure to the end of ampule 2 forces the closure 5 longitudinally within the'same and the closure acts as a piston discharging the liquid from the ampule through the needles 10 and 12.

surface of the ampule and protects the Ipisf ton from injury. In this construction illustrate a barrel 23 having a chamber 24 open at one end into which may be inserted the ampule or into which may be deposited the Huid to be applied, in either case the application of pressure on the end of the arrel forces the material longitudinally through needles 10 and 12 and discharges it from the end of needle 12. Y.

It will be observed that the closure for the single open end of the ampule serves as a piston and is punctured providing an outet for the fluld.
