Embodiment Construction

[0016] The present invention is described below in conjunction with embodiment.

[0017] The process adopts absorbent cotton to produce soluble hemostatic material, and chemically processes natural cotton fibers, which not only retains the state of cotton fibers but also obtains a soluble effect. During use, the soluble hemostatic material swells after absorbing water to make its tissue disintegrate and turn into transparent gelatin, and finally melts completely. Compared with ordinary hemostatic gauze or hemostatic cotton, soluble hemostatic materials have their own unique features in the process of use. They are more convenient and effective in tooth extraction, nasal cavity surgery, gynecological surgery, plastic surgery, etc., absorb water, dilute and decompose more thoroughly, and speed up. Faster, more gentle contact with the wound surface than hemostatic gauze, which is conducive to better wound healing. Its hemostatic function is produced through the following two way...

Abstract

A production technology of a soluble hemostatic material is beneficial to safe production, and improves a production capability or guarantees stability of product quality. The production technology comprises the following steps of: (1) soaking absorbent cotton into normal saline or saline solution; (2) placing the absorbent cotton soaked by the saline into a stainless steel alkalified reaction tank soaked through hydrochloric acid, and alkalifying the absorbent cotton into an alkalified reaction solution in the stainless steel alkalified reaction tank; (3) placing the alkalified absorbent cotton into a stainless steel etherification reaction tank soaked through hydrochloric acid, etherifying the absorbent cotton in an etherification reaction solution in the etherification reaction tank, thereby modifying the absorbent cotton to cotton fiber state sodium carboxymethylcellulose under a primary cotton fiber state; (4) performing the first alcohol washing for the cotton fiber state sodium carboxymethylcellulose; (5) neutralizing the cotton fiber state sodium carboxymethylcellulose after being carried out the first alcohol washing with hydrochloric acid; (6) performing the secondary alcohol washing for the neutralized cotton fiber state sodium carboxymethylcellulose; and (7) draining the cotton fiber state sodium carboxymethylcellulose soaked through ethanol to obtain the soluble hemostatic material.

Description

technical field [0001] The invention relates to cotton fiber modification technology, in particular to a production process of a soluble hemostatic material. Background technique [0002] Soluble hemostatic material is a modified product of natural cotton fiber. Soluble hemostatic materials can quickly stop bleeding and are non-toxic and have no side effects, and are more convenient to use. They can be used for diffuse bleeding and small venous bleeding on various surgical wounds, and the hemostatic effect is particularly significant for patients with coagulation mechanism disorders. Hemostasis in various surgical operations such as burns, plastic surgery, urology, oral cavity, ENT, anorectal, gynecology, neurosurgery, tumors, etc., as well as first aid fields such as daily wound care, natural disasters, traffic accidents, and military field operations. Soluble hemostatic materials are not only suitable for various types of bleeding, but also form a protective gel barrier o...
