A kind of medical alginate hydrogel and its production process and application

Abstract

The invention discloses a medical alginate hydrogel, a production technology and applications thereof. The technology comprises the following steps: step one, dissolving sodium alginate with a purity of 100% into distilled water; step two, preparing calcium alginate nonwoven cloth with a purity of 100%; step three, soaking the calcium alginate nonwoven cloth into the sodium alginate solution until the fibers of the calcium alginate nonwoven cloth are completely removed so as to obtain transparent medical alginate hydrogel. The provided alginate hydrogel is prepared by mixing two alginate products; alginate is a biological product extracted from alga, has a self-bactericidal function, will not be adhered on the wounds, can form a wet growth environment on the wounds, has a high oxygen transmission rate, and can be biologically degraded. At the same time, the sodium ions are replaced by calcium ions, solid moulded transparent hydrogel is obtained, and the provided medical alginate hydrogel can be directly made into products containing hydrogel blocks according to the final requirements of products.

Description

technical field [0001] The invention relates to a medical alginate hydrogel, a production process and an application thereof. Background technique [0002] There are many types of medical hydrogels. Generally speaking, it is composed of deionized water plus some polymer copolymers and cross-linking agents to form a gel. Existing medical hydrogels are all liquid and cannot be molded in actual use. Therefore, they can only be filled in various types of packaging bags, such as medical cooling patches packaged in plastic bags, or When in use, it can only be applied to the surface of the injured patient. When it needs to be removed, the residue on the injured part must be cleaned, which brings inconvenience to use; at the same time, the existing medical hydrogels generally cannot achieve Biodegradable. The so-called biodegradable means that the hydrogel is generally composed of polymer compounds. After being attached to the surface of human wounds, it cannot be absorbed by huma...

Existing medical hydrogels are all liquid and cannot be molded in actual use. Therefore, they can only be filled in various types of packaging bags, such as medical cooling patches packaged in plastic bags, or When in use, it can only be applied to the surface of the injured patient. When it needs to be removed, the residue on the injured part must be cleaned, which brings inconvenience to use; at the same time, the existing medical hydrogels generally cannot achieve Biodegradable. The so-called biodegradable means that the hydrogel is generally composed of polymer compounds. After being attached to the surface of human wounds, it cannot be absorbed by human tissues, which may easily cause allergies or secondary injuries.
