Problems solved by technology

[0004] The technical problem mainly solved by the present invention: aiming at the defects that the current traditional medical gauze cannot effectively block the invasion of bacteria and harmful particles, cannot promote granulation growth and skin regeneration, accelerate healing, and reduce scars, the present invention firstly prepares magnetic far-infrared ceramics, Soak micro-rot in biogas liquid rich in microorganisms, freeze and pulverize with liquid nitrogen, modify its surface with natural resin peach gum, add natural resin particles on the surface, improve the compatibility between powder and polyester matrix, and then The magnetic far-infrared polyester fiber is prepared by melt spinning, and finally woven into medical gauze. The invention utilizes the gauze to simultaneously emit far-infrared rays and magnetic field lines, and synergistically promotes blood vessel expansion in wound tissue, accelerates metabolism, and promotes blood microcirculation and interstitial inflammation. The absorption of exudate can promote the growth of granulation and epithelial cells, thereby promoting wound healing, and has excellent application prospects

Abstract

The invention discloses a preparation method for medical gauze for promoting healing and belongs to the technical field of medical supplies. The method comprises the following steps: firstly, preparing a magnetic far infrared ceramic; soaking and slightly corroding with marsh gas rich in microorganisms; performing liquid nitrogen freezing and crushing; modifying the surface with natural resin peach gum; adding natural resin grains on the surface, thereby increasing the compatibility between the powder and the polyester matrix; performing melt spinning, thereby acquiring a magnetic far infrared polyester fiber; and finally, weaving into the medical gauze. According to the invention, the medical gauze is utilized to simultaneously emit far infrared rays and magnetic lines which can synergistically promote the wound tissue angiectasis, quicken metabolism, promote blood microcirculation and absorption of inflammatory exudates between tissues and accelerate growth of granulation and epithelial cells, so that the medical gauze can promote the wound healing and has excellent application prospects.

Description

technical field [0001] The invention discloses a preparation method of medical gauze for promoting healing, which belongs to the technical field of medical supplies. Background technique [0002] Traditional trauma dressings are mostly pure cotton products, which are cooked with lye at high temperature, rinsed, and dried to obtain degreased gauze. In clinical practice, this kind of degreased gauze is used to bandage the wound of the wounded. It absorbs, dries and hardens in a short period of time, and becomes a stiff plate, which makes the gauze adhere to the new granulation. These plates not only compress the wound surface and affect tissue growth, but also destroy the healing wound when changing the dressing, causing secondary trauma and adding new pain to the wounded. [0003] At present, the materials used to load antibacterial drugs to treat wounds mainly include: chitosan, alginate, gelatin, etc., because chitosan and its derivatives have good hemostatic, analgesic an...
