Rapid hemostat suitable for war wound massive hemorrhage

Abstract

The invention discloses a rapid hemostat suitable for war wound massive hemorrhage, and relates to the technical field of medical instruments; the rapid hemostat comprises an injection mechanism and ahemostatic material, wherein the injection mechanism comprises an injection cylinder, a piston, an injection cylinder front cover and a percussion assembly; the hemostatic material is composed of barium sulfate powder with a diameter of less than 2 [mu] m, chitosan particles with a high deacetylation degree (greater than 90%) and a diameter of 2 mm, and prothrombin powder. The chitosan particlesin the hemostatic material rapidly expand to press a bleeding point, prothrombin is combined to promote fibrinogen to be converted into fibrin solidified blood to achieve the purpose of rapid hemostasis; and the chitosan particles are filled with barium sulfate powder which can be developed under X-ray radiography, so that identification and thorough taking of rear hospitals are facilitated. The rapid hemostat has the advantages of being simple, safe, economical and practical, is suitable for bleeding which is not prone to compression control and is caused by trauma of a body joint area and ajunction area and damage to large blood vessels, and is exact in hemostasis effect and high in hemostasis speed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rapid hemostatic device suitable for massive bleeding caused by war wounds. Background technique [0002] The treatment of war wounds has always been a challenge to military medicine, and bleeding is the main cause of death from war wounds. Once a person experiences trauma and causes bleeding, it is most important to stop the bleeding at the front line. Preferably, hemostasis can be formed locally, which is defined as the ability to locally stop bleeding from an injured vessel. [0003] In combat and post-hospital settings, time to control life-threatening bleeding is limited, and the severity and irregularity of the wound exacerbates the difficulty of bleeding control. The majority of combat bleeding mainly involves the extremities, and it has been proven that deaths from extremity trauma-induced hemorrhage account for more than half of all preventable deaths on the ...

AI Technical Summary

Problems solved by technology

Among them, the widespread use of tourniquets has saved countless lives, but when trauma occurs in joint areas and junctional areas of the body (such as neck, armpit, groin, perineum) and damages large blood vessels, these types of bleeding are difficult to control with compression

Pressing the hemostat with gauze delays other operations and transfers by the emergency responders. Tourniquets are not conducive to use at joint joints, and prolonged use of tourniquets will cause tissue damage.
