Problems solved by technology

In the past, it was believed that the wound needs to breathe, and maintaining the air permeability of the wound is an important factor for an ideal dressing, but new research proves that an oxygen-free atmospheric environment can promote the proliferation of blood vessels, thereby accelerating wound healing

Abstract

The invention belongs to the technical field of medical biological materials, and particularly relates to an antibacterial medical cold compress hydrogel and a preparation method thereof. According to the antibacterial medical cold compress hydrogel disclosed by the invention, a water-soluble polymer, succinylated modified starch, collagen, a cross-linking agent and deionized water are taken as a raw material system, and the starch is subjected to succinylated modification so as to further improve the gel performance, the water absorption performance and the strength performance of the starch, so that the gel content, the gel strength and other mechanical properties and the water absorption performance of the whole hydrogel system are effectively improved, the cooling effect of the hydrogel can be achieved, and the advantage of cooling is further utilized, so that the hydrogel has the effect of relieving pain; and due to the addition of the antibacterial agent, the antibacterial performance of the whole hydrogel system is effectively improved, and the medical value is better.

Description

technical field [0001] The invention belongs to the technical field of medical biological materials, and in particular relates to an antibacterial medical cold compress hydrogel and a preparation method thereof. Background technique [0002] The rise of hydrogel dressings benefited from a major conceptual breakthrough in wound healing in the 1980s. Previous treatments believed that wounds need to breathe, and maintaining the air permeability of wounds is an important factor for ideal dressings, but new research proves that an oxygen-free atmospheric environment can promote the proliferation of blood vessels, thereby accelerating wound healing. Hydrogel dressings have been widely valued due to their advantages of automatically adjusting the moisture of the wound, absorbing a small amount of exudate, not sticking to the wound, and being easy to remove. [0003] A conventional hydrogel is a polymer material with a three-dimensional cross-linked network structure, and water is ...
