Chinese patent CN10302788A reports a kind of absorbable medical dressing and its preparation method, the growth factors are added in its medicinal ingredients, but its preparation process is relatively complicated; Patent CN102671231A reports a preparation method of a marine source composite dressing, using marine fish A dressing prepared by extracting collagen from the epidermis and adding growth factors and related functional components, but the dressing contains many medicinal ingredients and has certain toxic and side effects; similar patent reports on growth factors include CN102078636A, CN103007339A, CN102397585A and CN104288828A Wait
However, for operations or deep wounds with fissures, it is still necessary to rely on sutures, which brings unconsciousness and pain to patients.

Abstract

The invention discloses a growth factor compound dressing capable of adhering a tissue fissure and a preparation method thereof. The compound dressing comprises an alginate gel layer and a non-woven fabric layer, wherein the alginate gel layer is prepared from sodium alginate, calcium carbonate, glucolactone, glycerinum, sodium carboxymethyl cellulose, allantoin, alpha-cyanoacrylate, cell growth factors and a protective agent. The dressing can be used for replacing a suture line to a certain extent, radically effectively promoting wound healing to prevent pains of surgical suturing for patients with relatively deep wounds, and effectively reducing generation of scars.

Description

technical field [0001] The invention belongs to the field of medical dressings, in particular to a growth factor composite dressing capable of bonding tissue fissures and a preparation method thereof. Background technique [0002] After the skin has been damaged or cut, the normal healing response leads to the formation of scars. The healing process of damaged skin consists of three phases—an inflammatory phase, a granulation phase, and a remodeling phase of the matrix. In the phase of inflammatory response, a series of biochemical reactions such as changes in vascular dynamics, increased vascular permeability, and swelling at the injured site appear. Local tissue degeneration, exudation, and proliferation are used to eliminate and repel foreign lethal cells, laying the foundation for the mission. During the granulation stage, fibroblasts secrete a large amount of collagen, elastin and fibronectin, etc., and form a large number of collagen fibers, but collagenase continue...
