HYPODERMlC-SYRINGE CASE.

SPECIFICATION forming part of Letters Patent No. 650,348, dated May 22, 1900. Application filed January 25, 1900. Serial No. 2,743. (No model.)

To an whom it may concern:

Be it known that I, CHARLES WITKOWSKI, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Hypodermi'c Cases, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a compact, light, and convenient case for transporting and protecting a hypodermic syringe when not in use, the case being so constructed that it can be readily slipped into the pocket of the user, and thus be carried in such manner as to be accessible at all times.

Hypodermic cases as now constructed are bulky and inconvenient to use, so far as I am aware, and are not adapted to be cleansed or sterilized in approved manner, While I have particularly adapted my novel case for easy cleansing, sterilization, or boiling, the entire device being made, preferably, of metal of non-corroding character or treated in suitable manner, as by nickel or silver plating.

Various novel features of myinvention will be hereinafter described, and particularly pointed out in the following claims.

Figure 1 is a front elevation, partly broken out, of a hypodermic case embodying one form of my present invention in condition for transportation with the syringe locked therein. Fig. 2 is a rear elevation thereof, also broken out, but showing the case unlocked preparatory to use; and Fig. 3 is a perspective View showing the case resting on a table or other support, the contents of the case be ing conveniently ready for immediate use.

In the present embodiment of my invention I have shown the case as comprising a plurality of cellular or tubular compartments a I), placed side by side in a row or bank. The central compartment 7) is shown as symmetrically located relative to its fellows and of larger diameter for a purpose to be described. The lower ends of the compartments a are closed by tightly-fitted plugs a, preferably threaded into the end of the compartment, each plug having an ejectingspring 3 attached to its inner end, (see Figs. 1 and 2,) the free end of the spring supporting a follower 3, which is stopped by a shoulder 30 in the compartment. These smaller compartments are intended to contain suitable vials o for morphine, brandy, &c., one of the compartments receiving the holder t, Figs. 2 and 3, for the syringe-needles. The case, springs, and other parts are preferably made wholly of metal, such as brass and steel, nickel-plated, so that the case may be thrown bodily into an antiseptic solution,sterilized, or subjected to dry heat without injury thereto.

The barrel D of a hypodermic syringe is usually provided with a threaded nozzle 6V, to which the needle is attached, it being a common practice among medical practitioners to disconnect the barrel and needle when the syringe is not in use.

In connection with other features to be described I make use of the barrel of the syringe to assist in looking it and the other contents of the case in place therein under normal conditions.

A tubular open-ended slide d is fitted to be moved longitudinally and rotatively in the large compartment 1), and I have herein shown (see Fig. 2) a lug or projection b on said slide extended into a slot 5 6 in the wall of the compartment 1), the outer end of the straight portion 5 limiting direct outward movement of the slide, while the spiral part 6 provides for a part rotation of the slide when extended. The length and direction of the part 6 of the slot is sufficient to turn the slide through an angle of substantially ninety degrees as the lug b travels from end to end thereof, the straight portion 5 of course preventing any rotation. An ejecting-spring s Fig. 2, is inserted between the inner end of the slide b and the bottom b of the compartment to normally eject ormove the slide outward. The bottom b has extended loosely through it the reduced end of a spindle 0 within the compartment 12 and provided with a threaded socket c at its opposite end, (see dotted lines, Fig. 2,) the end 0 being secured in any suitable manner to a thumb nut or cap 0 external to the compartment, whereby the spindle 0 may be rotated readily, but with no longitudinal movement.

It will be seen from the drawings that the compartment 1) is shorter than the other ones in order to provide room for and protect the nut or cap 0 as illustrated clearly in Figs. 1 and 2.

The outer end of the slide b is provided with a lateral arm b herein shown as oppositely extended, and long enough to project W A M over the open mouths of the smaller or auxiliary compartments a, Figs. 1 and 2. This arm maybe notched, if desired, as at 12, Fig. 3, to engage lugs let on the case when the latter is closed and locked, such lugs and notches then cooperating to position the arm.

When using the case, the needle isun-f screwed from the barrel D of the syringe and the barrel is inserted in the slide 1) with the nozzle d inward, the usual collar d on the barrel engaging the outer end of the slide. The barrel and slide are then pushed into the compartment 1) against the spring s until the socket c of the spindle 0 can engage the nozzle d of the barrel, and then rotation of the spindle by nut 0 will draw the barrel into the compartment until the arm 17 is adjacent to and closes the mouths of the compartments a, such condition being shown, in Fig. 1, the case and its contents being ready for transportation, closed, and locked. To prevent rotation of the barrel D when the spindle c is rotated, I prefer to provide the collar pl of the barrel with oppositely-extended projections d to engage upturned lugs 11 on the lateral arm 6 and when the syringe is in use the projections d afford a convenient holding portion for the fingers.

The case is preferably made slightly concavo-convex transversely to fit snugly in a vest-pocket or in the breast-pocket of a coat.

When the case is locked, the contentsof the various auxiliary compartments a will be completely inclosed and protected, as will be manifest from Fig. 1, and the barrel D is held in the main compartment 1).

To use the syringe, the nutof cap e is ,rotated to unlock the barrel-nozzled from the spindle c, and as soon as this is effected the spring 0 ejects the slide 11 and the barrel into the position shown in Fig. 2, the arm b being moved away from the mouths of the compartmerits a. At the same time the ejectingsprings s are free to act, moving the vials 1) or holder 2. outward, the arm 17 acting as a guard to prevent the springs from throwing the articles out of the compartments. The slide is then turned with the fingers to cause the lug b to enter the part 6 of the slot in the wall of the main compartment 1), and thereby the arm 12 is turned at substantially right anglesto the case, which can be placed one table orother support M, Fig. 3, With the open mouths of the compartments turned up, so that any portion of the contents of the case can be readily withdrawn. Until the lug b is passed into the curved part 6 of the guideslot the arm 19 guards, though not closing, the compartments 0,.

Manifestly the syringe-barrel could be held by the fingers to prevent rotation during the locking or unlocking operation described; but for convenience and ready handling I prefer to use some means for preventing such rotation as described.

It is a great convenience to have small supplies of drugs at hand when using hypodermic syringes and also to. have a compact case for the latter, and by the cellular structure of my case I provide not only for the syringe, but for drugs or other articles which can be carried at the same time.

My invention is not limited to the construction and arrangement shown, for I have illus trated and described one practical embodiment of my invention without attempting to illustrate the various modifications or changes which may be made without departing from the spirit and scope of my invention.
