. 4, 1934. R. E. POLHEMUS MEDICAL CASE Filed Dec. 30, I932 w r 5 0 M mm 0 E0 H mm A w WITNESSES Patented Dec. 4, 1934 UNITED STATES PATENT "OFFICE.
This invention relates to medical cases, and more particularly to a case or cabinet in which all articles necessary for use by diabetics may be kept. 7 5 A further object is to provide a relatively smallportable'device which may be carried about on the person of the user, and which not only carries all necessary equipment for insulin injections but also provides improved means for sterilizing hypodermic needles.
My invention has particularly to do with an improved arrangement of an electric heater and a sterilizing cup in which the needle is held so as to prevent any contact of the point of the needle with the interior of the cup during the sterilizing operation.
A further object is to provide a device of this character in which an electric heater is employed and in which a compartment is pro- 2 vided for the storage of the electric wire or f conductor so that needles may be sterilized before use and in a most convenient manner.
With these and other objects in view, the invention consists in certain novel features of construction and combinations and. arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawing,
Figure 1 is a perspective view illustrating an improved device;
Figure 2 is a view partly in elevation, but mainly in section, on the line 2/2 of Figure 1, Figure 2 being on an enlarged scale;
Figure 3 is a top-plan view of my improved sterilizing cup;
Figure 4 is a top plan view of the sterilizing cup illustrating a modification; and
Figure 5 is a view in section on the line 5/5 40 of Figure 4.
1 represents a box or case having a hinged cover 2, with suitable locking means 3 to secure the cover in closed position. The box or case 1 has a compartment 4 at one end for the accommodation of an electric wire or other suitable electrical conductor, and suitable attachments for plugging into an electric circuit. 6 represents a plug which may be conveniently employed, and 7 is a switch, all of which may constitute portions of the flexible conductor 5 and may be stored in the compartment 4.
The main portion of the box or case 1 has a platform cover 8 which is provided with openings for the accommodation of a plurality of receptacles 9 and a bottle 10 which may contain insulin. This platform 8 also provides clamps 11 in which a hypodermic syringe 12 may be ,removably held. The platform also provides an opening for the accommodation of a. container 13 for hypodermic needles, and suitable non-metallic buttons 14 are preferably provided in the cover 2 to engage the various receptacles 9 and prevent accidental movement of the latter.
Itis to be understoodthat my invention is not, limited to the particular 1' construction and arrangement of containers as it is capable of a wide variation, but it. is also to be understood that the containers are in the number, size and arrangement for the best storage of equipment for use by diabetics.
I call particular attention to my improved electrical heater 15 which is supported in an opening 16 in the platform 8, and is electrically connected to the conductor 5 so that whenever desired the heater may be electrically connected and generate heat. The heater 15 is preferably of the removable type so that it can be replaced whenever the heating element loses its eificiency, and with this idea the heater has a screwthreaded plug 1'7 which screws in a threaded socket 18 in the case.
In connection with the electric heater 15 I employ an improved construction and arrangement of sterilizing cup 19. This cup is of general cylindrical form, and has a recess 20 in its base so as to fit over the heater 15, and when the sterilizer is not in use this cup can be reversed and when the cover is closed it will be held against rattling.
The reference numeral 21 is employed to indicate a hypodermic needle. Needles of this character for use in hypodermic syringes for the injection of insulin are equipped with enlarged more or less rectangular shanks 22, and this shank will support the needle when in horizontal position above the bottom of the cup, but it is also desirable to prevent the needle from longitudinal and lateral movements, which will bring the point of the needle in contact with the Wall of the cup. To prevent this movement of the needle I provide the bottom of the cup 22 with a pocket 23. This pocket may be formed integrally on the bottom of the cup, as clearly shown in Figures 2 and 3 of the drawing, and consists of a raised ledge 24, with an inclined Wall 25 at the back of the pocket so that this ledge and wall form a rectangular space for the accommodation of the shank 22 of the needle 21. Furthermore, the inclined wall 25 insures the proper positioning of the needle even though it may have some movement due to the boiling action of water in the cup. In other words, water in its boiling action will flow down this wall 25 and tend to seat the inclined shank portion of the needle in the cup.
As a modification of this means for properly holding the needle in the sterilizing cup, I illustrate in Figures 4 and 5 of the drawing a removable frame 25 which rests on the bottom of the cup and has upwardly extending flanges 26 constituting a clamp to engage the rectangular shank 22 of the needle 21.
The employment of a case of this character is a great convenience to those who are compelled to use insulin either at home or while traveling, as it not only maintains the insulin and. adjuncts for the use thereof in proper, convenient assemblage, but it also provides an improved arrangement of sterilizer for the needle. It is of vital importance that the needle be sterilized and, hence, the provision of simplified, expedient means for accomplishing this purpose is of great valuein a case of this kind.
While I have illustrated what I believe to be the preferred embodiment of my invention, it is to be distinctly understood that various slight changes may be made with regard to the form and arrangement of parts without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.
What I claim is:
1. In a case of the character described, the combination with a support of an electric heater in the support, a sterilizing cup having a recessed bottom fitting over the heater, and capable of being reversed to support the same on the heater. 1
2. In a device of the character described, the combination with an electric heater, a sterilizing cup having a recessed bottom to fit over the heater, and means in the cup for so holding a hypodermic needle as to prevent contact of the point of the needle with the cup.
3. In a device of the character described, the combination with an electric heater, a sterilizing cup having a recessed bottom to fit over the heater, said cup having a pocket in its bottom for the accommodation of the angular shank of a hypodermic needle.
4. In a device of the character described, the combination with an electric heater,-a-sterilizing cup having a recessed bottom to fit over the heater, said cup having a pocket in its bottom for the accommodation of the angular shank for a hypodermic needle, the rear wall of said pocket being inclined.
