Patented May 21, 1946 UNITED STATES PATENT.OFFICE HYPODERMIC NEEDLE CASE Harry L. Swan, Brinkley, Ark.
Application July 10, 1944, Serial No. 544,281
This invention relates to hypodermic needle sterilizers, and more particularly to a combined needle sterilizer and hypodermic needle-carrying case.
The primary object of the invention is to maintain the hypodermic needle in a sterilized condition at all times, and ready for use, by submerging the needle in a sterilizing bath, while it is being supported within the case.
Still another object of the invention is to pro- 'vide a carrying case wherein the contents of the hypodermic syringe of which the needle forms a part, will be trapped within the syringe prevented from escaping, while the syringe is being carried.
With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing:
Figure 1 is a longitudinal sectional view through a case, illustrating the needle end of a hypodermic syringe as positioned within a base, constructed in accordance with the invention.
Figure 2 is a longitudinal sectional view through the sterilizing case.
Figure 3 is a sectional View through a modified form of the invention.
Referring to the drawing in detail, the device comprises a body indicated by the reference character 5, the 'body having an open end into which the needle end of a hypodermic syringe is positioned.
The body 5 is formed with a contracted portion 6 dividing the body into a chamber 1 for the reception of the hypodermic syringe, and a chamber 8 for the reception of the sterilizing fluid.
A rubber plug 9 completes the dividing wall within the body 5, and this plug is formed with an opening, through which the needle of the hypodermic syringe, indicated by the reference character I 0, is extended. One end of the chamber 8 is closed by the rubber plug H, the space between the plugs accommodating the sterilizing solution. The screw cap indicated at I2 is fitted on one end of the body portion and engages the plug ll, holding the plug H in position. The
plug H is formed with an opening to receive the lizing solution to insure the needle of being ready for instant use. It will also be seen that the case as shown by Fig. 2, provides a support for the hypodermic syringe, to hold the same in such position within the case, that it will not be broken when the syringe is being carried on the person.
In Fig. 3 of the drawing, I have illustrated a modified form of the invention designed preferably for use by dentists, wherein the casing would be supported under normal conditions, on a cabinet or table. In this form of the invention, the body which is indicated by the reference character I3 is supplied with a plug M which divides the body into a sterilizing solution chamber l5 and a chamber It in which the needle end of the hypodermic syringe is supported.
One end of the sterilizing solution chamber 1-5 is closed by means of the cap I! which holds the sealing disk I8 in position. By removing the cap and disk [8, the sterilizing solution may be readily removed or replenished.
From the foregoing it will be seen that due to the construction shown and described, the needle of a hypodermic syringe wil1 be maintained sterile and ready for instant use at all times.
It might be further stated that the rubber plugs or partitioning members are formed with recesses l9 to receive the ends of the syringes which are positioned within the casings, relieving the needles of strain which would be otherwise directed thereto.
What is claimed is:
l.-A syringe case having an open end in which the needle end of a syringe is positioned, said case having a contracted portion intermediate its ends, a rubber plug positioned within the contracted portion, dividing the case into a sterilizing solution-containing chamber, a removable rubber plug closing one end of the sterilizing solutioncontaining chamber, said plugs adapted to grip the syringe needle extended thereinto, supporting the needle with a portion thereof submerged in the solution contained within the compartment.
2. A syringe case having an open end in which the needle of a syringe is positioned, a rubber plug positioned within the case, dividing the case into a sterilizing chamber, a rubber plug closing one end of the sterilizing chamber, a cap for holding the latter plug in position, said plugs having aligning openings for the reception of the needle of a syringe, and said first mentioned plug having a recessed portion forming a continuation of the opening therein, adapted to accommodate one end of a syringe positioned within the case.
