Textile-based wound debriding material and manufacturing method thereof

Abstract

The invention provides a textile-based wound debriding material and a manufacturing method of the textile-based wound debriding material. The textile-based wound debriding material comprises a knitted composite structure. The knitted composite structure comprises ground weave and wool fibers, wherein the wool fibers are located on the front surface of the ground weave, and the root portions of the wool fibers and the ground weave are woven together and are bonded and fixed through adhesives. The textile-based wound debriding material is free of toxicity and good in biocompatibility; since the surface, in contact with a wound, of the textile-based wound debriding material is provided with the soft wool fibers, the surface of the wound can be debrided; due to ultrahigh hygroscopic property and cleaning ability of the textile-based wound debriding material, foreign mater and necrotic tissue at the wound can be removed; due to good flexibility and breathability, the textile-based wound debriding material can mitigate the pain of a patient in the debriding process; the back surface of the material is provided with the knitted composite structure, the knitted composite structure is woven on a circular weft knitting machine and is coated with the adhesives, and therefore the good dimensional stability, the supporting performance and the anti-linting performance of the material are guaranteed; the periphery of the material is subjected to edge covering, and therefore secondary pollution caused by scattering wool fibers or yarn on the periphery of the material is avoided.

Description

technical field [0001] The invention belongs to the technical field of biomedical textiles, in particular to a textile-based wound debridement material and a manufacturing method thereof. Background technique [0002] Wound refers to the different degrees of damage or destruction of skin and other tissues caused by normal tissues of the body under the action of various injury factors or pathogenic factors. With the development of industry and transportation, wounds such as cutting injuries, crushing injuries, and fractures are gradually increasing; with the change of lifestyle and the extension of the average life expectancy of the population, the incidence of chronic wounds such as diabetic foot, arterial ulcer, and venous ulcer greatly increase. [0003] Wound healing is a complex and orderly biological process, which mainly includes four stages: inflammatory response, wound reconstruction, wound epithelialization and wound remodeling, and involves the synthesis of variou...

AI Technical Summary

Problems solved by technology

However, due to the hard material and high rigidity of the bristles, the flow and pressure are not easy to control, which will cause certain damage to the patient's wound

In addition, the debridement brush needs to rely on external water sources during use, which consumes a lot of water, which will cause a certain degree of waste of water resources, and is accompanied by the generation of waste liquid containing pollutants such as necrotic tissue, which does not meet the requirements of safety and hygiene.
