Bionic cloth for stopping bleeding

Abstract

The invention belongs to the technical field of medical products, relates to a material for stopping bleeding and in particular relates to bionic cloth for stopping bleeding. The bionic cloth for stopping bleeding has a multilayered structure and comprises a repairing dissolving layer, an isolation and ventilation layer, a bleeding stopping medicine layer and a covering outer layer in sequence, wherein the repairing dissolving layer is cyanoacrylate tissue glue; the isolation and ventilation layer is formed by weaving cotton and hemp fibers; the bleeding stopping medicine layer is a medical treatment medicament; the covering outer layer is cotton and hemp fiber cloth; the repairing dissolving layer, the isolation and ventilation layer, the bleeding stopping medicine layer and the coveringouter layer are stuck and cured together through crosslinking; the bleeding stopping medicine layer is prepared from the following components in percentage by mass: 22 to 24 percent of mannitol, 0.5 to 12.6 percent of chitosan, 9 to 22 percent of vitamin C, 5.2 to 6.5 percent of dexamethasone, 2.0 to 2.2 percent of thrombin, 2.0 to 3.2 percent of polyvinyl alcohol, 0.2 to 0.5 percent of sodium dodecyl sulfonate, 0.5 to 7.2 percent of modified zeolite and the balance of starch micro-pore polysaccharide granules. After the product absorbs a lot of blood, the volume is expanded so that blood vessel ruptures or wounds are sealed and a barrier is provided for a bleeding stopping opening; the bionic cloth has a more rapid healing speed and a better effect.

Description

Technical field [0001] The invention belongs to the technical field of medical supplies, and relates to a material for hemostasis. Background technique [0002] Hemostasis is an important step in emergency medical treatment. When patients undergo surgical treatment and sudden trauma in daily life, rapid hemostasis is required. In the harsh environment of war and complex emergencies, emergency treatment of war and trauma is achieved. Fast and effective hemostasis is particularly important. At present, the hemostatic materials on the market mainly include fibrin glue, gelatin sponge, microporous inorganic materials, carboxymethyl cellulose soluble hemostatic gauze and so on. They are effective in hemostasis, but they also have shortcomings: products such as fibrin glue source, zeolite, fiber, etc., have high cost, poor fusion absorption performance, lack of repairing scars, single performance, low hemostatic efficiency, poor applicability, and easy to spread diseases Collagen rel...

AI Technical Summary

Problems solved by technology

They have exact hemostatic effect, but they also have disadvantages: such as fibrin glue source, zeolite, fiber and other products, the cost is high, the fusion and absorption performance is poor, the scar repair is lacking, the performance is single, the hemostatic efficiency is low, the applicability is poor, and it is easy to infect diseases ;Collagen relies solely on the activation of platelets to stop bleeding, the hemostatic effect is limited, and the tissue adhesion is poor; Porous zeolite will release a lot of heat energy after absorbing blood water, which will lead to wound inflammation; Carboxymethyl cellulose soluble gauze cannot be degraded on the wound surface, Easy to produce scars when removed
