SYRINGE.

Specification of Letters Patent. Patented J 1 p 1921 Application filed July 3, 1920. Serial No. 393,894.

To all whom it may concern:

Be it known that I, SAMUEL E. VVEINER, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented new and useful Improvements in Syringes, of whlch the following is a specificatiom An object of the invention 1s to provide a syringe for the application of a fluid solution or salve.

The invention is particularly adapted to syringes used for medicinal purposes and preferably relates to the kind and character of syringes generally employed 1n the treatment of venereal diseases. To this end the invention comprehends a syringe provided in the interior of the cylinder thereof, with a suitable medicament or prophylactic, which is so disposed that when a quantity of fluid is drawn into the syringe and the syringe shaken, the fluid will with the medicament or prophylactic, form a solution which can be subsequently ejected to the afflicted part when the movement of the plunger is reversed and the plunger pressed forward. The plunger furthermore is designed and shaped to also act as an applicator and to this end the cylinder of the syringe may be provided with a plug of a quantity of a salve so that upon the withdrawal of the plunger from the cylinder, the salve adhering to the plunger, can be conveniently applied by the amplication of the head of the plunger, covered with the salve, to the part requiring the application of such salve.

In the further disclosure of the invention, reference is to be had to the accompanying drawings constituting a part of the specification, in which similar characters of reference denote corresponding parts in all the views, and in which,

Figure 1* is an elevation of the syringe.

Fig. 2- is a vertical longitudinal sectional view, and

Fig. 3-.is a vertical transverse sectional viewtaken on the line 3-3 in Fig. 1.

Referring more particularly to the views, the numeral 10 indicates a cylinder preferably made of glass or some other convenient form of material and which at one end tapers to a point 11, provided with an aperture 12, the other end of the cylinder being preferably closed by a suitable cap 13 which may b applied in any convenient manner. A plunger 14 which includes a head 15, a stem 16 and a knob or handle 18 is adapted to be inserted in the cylinder 10 after which the cap 13 is applied and said cap is provided with an opening 19, through which the end of the stem 16 extends, the knob 18 being subsequently applied to the exterior end of said stem. The plunger furthermore on the head 15 thereof, is provided with a suitable packing 20, fitting closely to the interior wall of the cylinder so as to prevent leakage behind the head of the plunger.

A sack 21 containing a medicament which may be of a prophylactic nature, is inserted in the cylinder previous to the insertion of the plunger therein and will normally rest at the forward tapered end of the cylinder within the same. Now, when the plunger is drawn rearwardly in the cylinder with the head end of the cylinder previously inserted in a fluid, it will be apparent that the fluid will be drawn into the cylinder by the suction created by the plunger and that the fluid will of necessity, have to pass through the sack and medicament and thus will form a medicated solution within the cylinder and which solution may be more readily brought about by subsequently shaking the cylinder.

Now when the plunger is pressed forward, the fluid will be pressed out from the sack and the head end of the cylinder, to pass through the opening 12 and be applied to the atliicted part in the usual manner.

In instances where it is desired to apply a salve, it has been found that the plunger provides a very suitable applicator and to this end the rear portion of the cylinder may receive a plug or quantity of a salve 22, suitably inserted from the rear into the cylinder when the cap 13 is removed. This salve would not only help to lubricate the stem of the applicator causing it to operate more readily, but upon a withdrawal of the applicator from the cylinder, the salve would tend to adhere thereto and the plunger because of its peculiar pear shape, can now be conveniently adapted as an applicator for the application of the salve to the afliicted )art. I From the foregoing description it will be apparent that the particular pear shape of the plunger is of considerable importance in the proper use and operation of the de vice and it will also be apparent that the fluid drawn into the cylinder by the suction created when the applicator is retracted in the cylinder, will strain the fluid through the contents of the sack and of course the fluid will again pass through the sack when it is ejected. By providing the additional feature of having the plunger employed in the nature of an applicator, it will be apparent that my device serves a double pur pose, namely, it provides for the application of a fluid solution or a salve or ointment or both, as the case may be, it being well known that in the treatment of diseases of a venereal nature, it is oft-times desirable to apply both a fluid solution for the treament of interior parts or tissues and a salve or ointment for application to the exterior thereof.

Although of course, 1 preferably use my syringe for particular purposes and in connection with the practice of medicine, it will be understood that the same may be adapted to various uses and that I do not limit myself to any particular use, although particular uses of the syringe have been stated herein. Having described my invention, I claim 1. A syringe comprising barrel having a tapered apertured end, a medicament containing sack disposed in said end of the barrel and a plunger in said barrel and movable therein to draw a fluid through the aperture of the barrel and through the sack and its contents to the interior of the barrel and subsequently eject the resulting fluid solution upon the reverse movement of the Plunger in the barrel.

2. A syringe comprising a barrel having a tapered apertured end, a 1 medicament containing sack disposed in said end of the bar,

rel and an applicator in said barrel and movable therein to draw a fluid through the aperture of the barrel and through the sack and its contents to the interior of the barrel and subsequently eject the resulting fluid solution upon the reverse movement of the applicator in the barrel, a removable cap for the other end of the barrel and holding therein a plastic product applicable to the applicator upon its removal from-that end of the barrel when the cap has been removed.

In testimony whereof l affix my signature.

SAMUEL E. ,WEINER.
