First-aid hemostatic device

Abstract

Provided is a first-aid hemostatic device. The first-aid hemostatic device includes an exterior bearing unit and interior hemostatic materials. The exterior bearing unit is an injection-type coating device or a bag. The interior hemostatic materials have the functions of liquid absorbing and expansion, and include absorbable hemostatic materials and non-absorbable hemostatic materials; the hemostatic materials are round, powder, in a disc shape or cylindrical, and can be compressed; the hemostatic materials electively contain one or more therapeutic agents, hemostatic agents or inorganic salt and labels, wherein the labels are used for marking and being convenient for searching and taking the hemostatic materials out of the body; after being shaped, the first-aid hemostatic device is packaged in a germ-free mode. The first-aid hemostatic device is high in hemostatic performance, safe and reliable; the specifications of the hemostatic materials not only help expansion objects freely pass through narrow wounds but also are enough for making the expansion objects move to torn or perforated vessels, thrombi cannot be caused, and when expanded to be sufficiently large, the expansion objects are maintained at the high-flow bleeding wounds.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an emergency hemostasis device. Background technique [0002] Emergency hemostasis The hemorrhage caused by trauma, if not stopped and bandaged in time, will seriously threaten people's health and even life. [0003] At present, the commonly used emergency hemostasis methods are tourniquet band to stop bleeding and stuffing to stop bleeding. Tourniquet hemostasis refers to the treatment measures that use bandages, triangular bandages, tourniquets and other items to directly apply to the wound or ligate a certain part. Packing hemostasis means filling the wound with a first aid kit, cotton pad or sterilized gauze, and then bandaging it with pressure bandage. It is used for bleeding in thigh roots, armpits, shoulders, mouth, nose, and uterine cavity. These are commonly used simple hemostasis methods, which are often ineffective for some complicated wounds, and are l...

AI Technical Summary

Problems solved by technology

However, its defect is hemostasis and exothermic reaction at the same time, it is difficult to remove residual particles, causing organ damage and scar formation

The improved zeolite powder is packaged in non-woven bags, which avoids the damage of residual particles to organs, etc., but its hemostatic effect drops sharply, and although its exothermic reaction has been improved, the effect is still not obvious

[0006] In the process of emergency application, many problems have been highlighted in the use of previous hemostatic products. Now there is an urgent need for a product with good effect and small damage, which can be applied to wounds with cavities, especially joint joints, such as groin and armpits. Hemostasis, physical hemostasis cannot be used in such parts, that is, the compression of the tourniquet to stop bleeding

Moreover, in the process of hemostasis in the body, it will be more painful during use, and there is no auxiliary solution strategy

Therefore, none of the existing products can meet the first aid needs
