DEVICE FOR FACILITATING THE ADMINISTRATION OF SUBCUTANEOUS HYPODERMIC INJECTIONS Filed NOV. 25, 1959 In venior @272 swora k M A iiorneys Patented Apr. 15, 194i DEVICE FOR ISTRATION FACILITATING THE ADIVIIN- OF SUBCUT'ANEOUS H YPO- DERMIC INJECTIONS Julian R. Hollingsworth, Brawley, Calif. Application November 25, 1939, Serial No. 306,160 3 Claims. (Cl. 128-215) This invention is a device for use in connection with a hypodermic needle to facilitate giving hypodermic injections.
Among the objects of the invention is to proof this character which will the hypodermic needle and its component parts; to control the penetrating depth of the needle, and to facilitate the handling of the needle in administering the injection as well as the withdrawing of the needle after such administration.
The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:
Figure 1 is a perspective View of the device.
Figure 2 is a perspective view of the device but with the same shown in an inverted position.
Figure 3 is a bottom plan view of the device.
Figure 4 is a Figure 5 is a fragmentary sectional view therethrough illustrating the application of the invention,
Referring more in detail to the drawing it will be seen that the device comprises an oblong body 5 which may be made of metal, wood, or other suitable material and of any suitable dimensions, it being understood, however, that the thickness of the device will be such as to control the penetrating depth of the hypodermic needle, that is, to preclude the needle being inserted at a depth beyond that desired or required.
The block 5 adjacent the respective opposite ends thereof is provided with transverse arcuate notches 6 to accommodate two fingers of the hand so that the device may be conveniently held in position on the arm or other part of the anatomy, at the point where the injection is to be made.
Intermediate its ends the body block 5 is pro-' vided with an aperture or bore 1 of a diameter just slightly in excess of the diameter of the hypodermic needle 8 so as to permit ready passage of the needle therethrough without at the same time permitting too much play for the needle.
At the topside thereof the block 5 is provided with a socket or recess 9 of a size to accommodate the base or socket end 8a of the needle, and at the inner end of the socket the wall is concave so as to readily accommodate the base or socket portion 8a of the needle.
On the bottom side thereof the body block 5 is provided with a teat or protuberance l0 and the bore 1 extends from the inner end of the socket 9 through the protuberance ID as shown in Figure top plan view of the device, and
5 so that the device will readily accommodate the hypodermic needle.
The protuberance l0 will serve to stretch the skin and thus give partial pressure anaesthesia.
In actual practice the body block 5 is placed upon the selected part of the body at the point where the injection is to be made and firmly held in place with two fingers of one hand being accommodated in the groove 6 in a. manner thought apparent. The hypodermic needle with the syringe attached thereto is then passed through the bore 1 in the block and when properly positioned with respect to the block the needle is then plunged downwardly with a sharp, strong stroke to complete the injection. After the injection has been made the needle may be withdrawn through the block and the block then removed from the body.
It will thus be seen that with a device of this character the penetrating depth of the needle will be controlled; there will be no danger of the needle breaking off in the flesh; the needle will be held steady and against wobbling, and the protuberance l0 tending to stretch the skin at the point of the injection will permit easier penetration of the skin by the needle. The protuberance 10 also assists in giving partial pressure anaesthesia. Also with this device the syringe is held firmly while the operator changes from the hold thereon necessary to accomplish the injection to the hold thereon necessary to withdraw the needle.
Also, with this device much of the psychological fear in self-administered injections is removed and no high degree of skill is required in administering such injections.
It is thought that a clear understanding of the construction, utility, manner of use, and advantages of a device of this character will be had without a more detailed description.
Having thus described the invention what is claimed as new is: 1. A device to facilitate hypodermic injections comprising a block of elongated form and of a size to cover and hide from view a considerable part of the part of the body which is to receive the injection, said block having a substantially semi-spherical teat on one face thereof, the rest of said face being fiat to bear against the part of the body to receive the injection and said teat being spaced from the edges of the block and said block having a transverse passage therethrough which passes through the center of the teat and which is adapted to receive the needle of a hypodermic device.
2. A device to facilitate hypodermic injections comprising a block of elongated form and of a size to cover and hide from View a considerable part of the part of the body which is to receive the injection, said block having a substantially semi-spherical teat on one face thereof, the rest of said face being flat to bear against the part of the body to receive the injection and said teat being spaced from the edges of the block and said block having a transverse passage therethrough which passes through the center of the teat and which is adapted to receive the needle of a hypodermic device, the upper end of the passage being enlarged to receive the enlarged upper end of the needle and said block being of a predetermined thickness to control the penetrating upper face of the depth of that part of the needle projecting from the teat.
3. A device for facilitating hypodermic injections comprising an elongated rectangular block, a substantially semi-spherical teat projecting from the central part of one face of the block and said block having a needle receiving passage passing transversely therethrough which also passes through the center of the teat, the upper end of the passage being enlarged to receive the base part of a needle of a hypodermic device and the block having transversely extending finger receiving grooves therein, said grooves being placed between the center of the block and the ends thereof.
