May 17, 1938. R. T. WOODYATT INJECTION INSTRUMENT Original Filed April 28, 1933 JWDuerzZor (1)0039 Patented May 1?, 1938 umren STATES PATE NT OFFICE Application April 28, 1933, Serial No. 668,294 Renewed: March 26, 1937 14 Claims.

This invention relates to injection instruments, and has been illustrated .as including a hypodermic syringe and carrying case, together with various accessories so that the assembly will in- 6 elude everything necessary for the convenient and safe use of the instrument.

There are numerous people who frequently need to make injections of some medicinal fluid, such as insulin. For these people especially it is desirable that the necessary instrument and accessories be assembled in as compact and portable a form as possible, and that keeping the hypodermic syringe absolutely sterile as well as insuring its safe use be made as convenient as possible. The present invention has satisfied the need by providing an injection syringe in combination with an alcohol-containing holder, a needle rack anda cotton container, all compactly assembled in a tube not much larger than 20 a large fountain pen, which may be used for car rying the syringe in the pocket or which may be used as a rack for holding the alcohol container upright during use of the syringe.

With these andvarious other objects in view,

25 the invention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawing and claims ap pended hereto.

In the drawing, which illustrates an embodiment of the device, and wherein like reference characters are used to designate like parts,

Figure 1 illustrates the instrument in its assembled condition;

Figure 2 is a vertical cross-sectional view taken on line 22 of Figure 1;

Figure 3 is a greatly enlarged fragmentary sectional view showing the assembly of the needles onto the syringe;

Figure 4 is a view of the instrument with its parts separated as they would be during use; and

Figure 5 is a fragmentary vertical sectional View taken approximately through the line 55 of Figure 4.

Although my invention may take many forms, only one has been chosen for illustration. In this form, the outer case includes the tube 2, the cap 4, and the bottom 6. These parts may be made of any desired material, such as metal, though for the sake of appearance it is preferred that the tube 2 at least be coated with a more attractive substance, such as a decorative cellulose composition. The tube 2 may be provided with a pocket clip 8 and the cap 4 may be provided with a clip ID, the purpose of which is described.- be:

(Cl. l28.215)

low. Within the tube 2'is a container I 2 similar to a test tube. This container may be hermetically sealed to a top I4 which is provided with a metal flange l6 adapted torest on the edge of the tube 2. The clip Ill and.- its top M 5 should be sealed together as by a cement which is not soluble in alcohol. In the bottom of the tube l2 may be provided a suitable quantity of alcohol I8 or any sterilizing fluid for filling any bacteria which may get on the needles, and to furnish a supply for cleaning the skin at the spot where the injection is to be made. The syringe barrel 26, together with the parts associated therewith, is held in the container l2" by a rim 22. Between the rim 22 and the flange l5 there may be a rubber washer 24. The cap 41 is shaped with a shoulder 26 which squeezes the rim 22 against the rubber washer, which therefore makes a tight seal between the rim 22 and the flange l6.

As the usual custom, the barrel of the 20 syringe is provided with suitable calibrations to indicate the quantity of material held therein. There is also provided a customary plunger 28 having a snug ground fit with the syringe barrel. The plunger 28, the barrel 20, andthe container l2 are preferably all made of glass, that known commercially as Pyrex being preferred. The barrel 20 is also provided with a. tip 30' which is slightly tapered toward its lower end, and onto which is fitted a hub 32 of the hypodermic needle 34, which may be tapered with approximately the same taper as that of the tip 30, so as to make an air-tight seal therewith. This joint is of the usual form. The hypodermic needle 34 is nested into a filling needle 36, the hub 38 of which fits over an extension 40- on needle 34 as the hub 32 fits over the tip 30. By using the filling needle 36 for piercing the rubber cap of the insulin container, the hypodermic needle 34 may be kept sharper than would otherwise be possible.

Slipped over the end of the glass container I2 is a thin sheet metal rack 42, the construction and use of which are clearly shown in Figure 4.

Upstanding from the bottom 6 is a short tube 44 into which is pressed a supply of absorbent cotton 46.

The use of the instrument will now be briefly described: First, the cap 4 is unscrewed, and its clip H) is fitted under the clip 8 of the tube 2, as shown in Figures 4 and 5.. Next the bottom 6 is unscrewedand set in a convenient position, as shown in Figure 4. Then the container l2 and with it the hypodermic syringe is removed from the tube 2, and this tube is thereafter placed in. a convenient position with the. cap positioned open end up. The rack 42 is then removed from the container l2 and also placed in a convenient position, the container l2 being placed in the cap 4 to retain the container in a vertical position so that the alcohol will not be lost. It is preferred that the cap be provided with a split ring 48 or other spring steadying means, and if the split ring is used it may be bent fairly decidedly near one end, as at 5|], so as to press both against the cap and against the container l2. The

syringe with its needles is then removed from the container [2. The outer needle 36 is pressed through the rubber cap of the container of insulin or other medicinal substance, and insulin is drawn into the casing in the usual way by a partial withdrawal of the plunger 28. The filling needle 36 is then removed and rested on its hub, as shown in Figure 4. The syringe may then be rested on the rack 42, as is also illustrated in Figure 4, while the spot of skin at which the injection is to be made may be cleaned off. For this purpose cotton may be removed from the bottom 6 and moistened with alcohol from the container l2, and then used on the spot where the injection is to be made. The syringe is then removed from the rack and the injection made in the usual way.

The steps of taking apart just described are then reversed and the instrument intact is clipped to the pocket by the clip 8, ready for its next use. It is extremely complete and compact, provides for absolute sterility, and may be carried in the pocket or safely shipped.

It is to be understood that many other embodiments of the invention, including some in improved form, will be apparent, and in the course of time more will be devised by those skilled in the art. It is not desired that this invention be limited to the details described, for its scope includes all such forms or improvements as come within the spirit of the following claims, construed as broadly as the prior art will permit.
