Definitions

  • This invention relates'toinjectors and more particularly to an injector for injecting various sera, inoculations, and the like, between and beneath the layers of the skin. It is a primary object of this invention to provide such an injector, which is very easy to use and which is provided with safeguards. which insure its proper functioning, no matter how little experienced the operator.
  • the needle is so disposed with respect to the planning guide that the tip of the needle will be in practice disposed at exactly the desired depth beneath the surface of the skin. It is generally desirable in making intradermal injections to provide that the injection will be made below the epidermis and just above the corium. Accordingly, it is a feature of this invention that the tip of the needle is adjusted to make just this depth of penetration in the skin in normal persons. However, it is sometimes desired to make just a narrow furrow in the skin, and accordingly the invention contemplates that the needle may be disposed at a shallower depth or, as otherwise expressed, at
  • the needle may be adjusted for such deeper or subcutaneous injection.
  • Figure 1 is an isometric perspective elevation of the device embodying the present invention
  • Figure 2 is a plan view
  • Figure 3 is a fragmentary vertical section.
  • this invention comprises a base or plane member ID having formed integrally therewith a post I I in the form of a hollow cylinder.
  • a finger grip l2 in the form of an upstanding fin is also formed integrally with the base member I0.
  • the base I0 is cut out as at l3 and It.
  • the base l0, post II and fin ii. are preferably formed of poly-ethylene plastic and the walls of the post I l are considerably thinner than the walls of the base II) or the fin 52, as clearly shown in Figure 3.
  • the plug l5 has a central bore l6 in which may be positioned a hollow surgical needle I1.
  • the hollow surgical needle 11, as it exits from the plug [5, is bent at an acute angle to the bottom thereof, so as to position the point I8 forwardly of the plug and slightly below the bottom surface of the base Ii].
  • the needle l8 has its opening facing upwardly, as clearly shown in the figures.
  • the space between the tip of the needle and the bottom of the base ill will be carefully adjusted so as to give the proper depth injection. As pointed out above, it is usually desired that this distance be such that the needle will completely penetrate the epidermis and reach into the capillary section just above the corium. However, in subcutaneous injections, the needle may be disposed at an angle approaching 30 from the plane of the 'base Ill.
  • the interior of the post ll above the plug I5 is hollow, and it is contemplated that this space can be filled with any desired injecting material, such as sera, allergy inoculations, or antitoxins.
  • the device In operation, the device will be taken between the thumb and first finger of an operator and placed fiat, with the bottom of the base section II! lying directly on the surface of the skin. A short push of the device along the skin in the direction of the needle will cause the tip of the needle to penetrate the epidermis, as shown in Figure 3. With the needle thus in place the operator will collapse the thin walls of the post II in the space above the plug l5 and thus inject the desired injection between the skin of the patient.
  • the bottom of the base ID as it contacts the surface of the skin, acts as a planing guide and assures that the needle will penetrate to just exactly the desired depth, and the V-shaped opening formed by the cutout portions [3, l4 serves to slightly pinch the skin and somewhat raise it to insure puncture by the needle.
  • said needle has a pointed end and an upwardly disposed opening adjacent said end.
  • An injector as set forth in claim 2 in which said end is disposed forwardly of said skin contacting surface and below said surface a distance substantially equal to the thickness of a normal human epidermis.
  • An injector comprising: a base member having an extended skin contacting surface; a member associated with said base member and having a hollow portion adapted to be filled with fluid; a plug closing said hollow portion; a hollow needle in said plug communicating with said hollow portion and'having a part thereof extending below and substantially parallel to said skin contacting surface.

  • An injector comprising: a base member having a substantially flat and extended skin contactin surface; a hollow post upstanding from said base member and having a closed upper end; a plug in the lower end of said post; and a hollow needle in said plug communicating with said hollow post and having a part extending below and substantially parallel to said skin contacting surface, in which said needle has a pointed end and an upward disposed opening adjacent said end.
  • An injector comprising: a base member having a substantially fiat and extended skin contacting surface; a hollow post upstanding from said base member and having a closed upper end; a plug in the lower end of said post; and a hollow needle in said plug communicating with said hollow post and having a part extending below and substantially parallel to said skin contacting surface, in which said hollow post has thin walls .10 contacting surface;
  • said needle adapted to be compressed by the fingers to eject said fluid
  • said needle has a pointed end and an upwardly disposed openin adjacent said end, and in which said end is disposed forwardly 5 of said skin contacting surface and below said surface a distance substantially equal to the thickness of a normal human epidermis.
  • An injector as set forth in claim 6 in which said base is provided with a substantially ver- 10 tically extending fin adapted to be gripped by the fingers of an operator for pushing the injector forwardly over the skin of a patient.
  • An. injector comprising: a base member having a substantially fiat and extended skin con- 2 tacting surface; a hollow post upstanding from said base member and having a closed upper end; a plug in the lower end of said post; and a hollow needle in said plug communicating with said hollow post and having a part extending below and substantially parallel to said skin contacting 3 said end; said end being disposed forwardly of said skin contacting surface and below said surface a distance substantially equal to the thickness of the normal human epidermis; said base being provided with a substantially vertically extending fin adapted to be gripped by the fingers of an operator for pushing the injector forwardly over the skin of a patient.
