Embodiment Construction

[0039] The present invention is described in detail below in conjunction with accompanying drawing description:

[0040] The present invention comprises a patch for sticking on the skin surface, an elastic cover body 2 whose opening is fixedly covered on the upper surface of the patch, and several hypodermic syringes arranged inside the elastic cover body 2;

[0041] The hypodermic syringe includes a piston rod 31 whose upper end is fixed on the inner surface of the elastic cover body 2 , an injection barrel 32 sleeved outside the piston rod 31 , and a microinjection needle 33 fixed at the front end of the injection barrel 32 .

[0042] At present, most of the research on analgesia for war wounds in the world is focused on the development of analgesic drugs, but there is little research and development on analgesia devices for war wounds;

[0043] The use of analgesics is usually divided into two categories: smearing and injection. The smearing method can only provide short-te...

Abstract

The invention relates to the field of medical instruments, in particular to a miniature adhesive subcutaneous injection device. The miniature adhesive subcutaneous injection device comprises an adhesive film, an open elastic cover and a plurality of subcutaneous injectors, wherein the adhesive film is used for being adhered on the surface of the skin, the elastic cover fixedly covers the upper surface of the adhesive film, and the subcutaneous injectors are arranged inside the elastic cover. Each subcutaneous injector comprises a plunger rod, an injection needle cylinder and a miniature injection needle, wherein the upper end of the plunger rod is fixed on the inner surface of the elastic cover, the injection needle cylinder sleeves the plunger rod connectively, and the miniature injection needle is fixedly arranged at the front end of the injection needle cylinder. By the miniature adhesive subcutaneous injection device, self rescue of individual soldiers in battlefields is facilitated, and the problem of war wound analgesia can be solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a paste-type miniature hypodermic injection device. Background technique [0002] Pain is the main complication of war injuries. According to research, besides inflammatory pain in the acute pain of war wounds, the hypersensitivity of other local wounds is mainly mediated by sensitive Aδ fiber nociceptors, and some non-sensitive / silent Aδ fiber nociceptors are mediated by cutting stimuli. Transformation into hypersensitivity, local lactic acid accumulation and lower pH value in the wound suggest that ischemia, hypoxia and hypoperfusion factors are also involved in the formation of postoperative pain. [0003] During World War II, the U.S. military equipment used a "Siret Morphine Hypodermic Syringe" developed and produced by Bristol-Myers Squibb, so that medical and health personnel could effectively inject a controlled amount of morphine to the wounded on the front line, which ...
