Oxygen release hydrogel dressing and preparation method thereof

Abstract

The invention provides an oxygen release hydrogel dressing. The oxygen release hydrogel dressing is characterized by comprising a first dressing and a second dressing, wherein the first dressing is prepared from a hydrogel dressing body, glucose, an oxygen release catalyst and a polyester mesh sheet having a pore structure, the second dressing comprises a hydrogel dressing body and glucose oxidase, and the first dressing and the second dressing cooperate for use. The oxygen release hydrogel material provided by the invention has good water vapor permeability and good water absorption performance, and a final product can release oxygen, iodine elementary substances and water after being in contact with air, so that the oxygen release hydrogel material as a novel functional material can be used for various acute and chronic wounds, can autonomously remove exudate of damaged tissue, and can guarantee a wet wound environment; and besides, the local oxygen concentration is also increased, anti-inflammatory iodine elementary substances are released, and the oxygen release hydrogel material has the effects of relieving wound pain and accelerating the healing speed of the damaged tissue.

Description

technical field [0001] The invention relates to the field of medical polymer materials, in particular to an oxygen-releasing hydrogel material and a preparation method thereof. Background technique [0002] According to statistics, the annual cost of wound treatment in the world reaches 13-15 billion US dollars. Tens of millions of people in China have skin trauma caused by accidents and operations every year. Chronic refractory wounds have become a difficult problem in the field of wound care, with the characteristics of a large patient base, high difficulty in healing, and high treatment costs. [0003] The theory of wound treatment is also constantly updated. In 1962, Dr. Winter of the University of London pointed out that the wound healing speed in a wet environment is twice as fast as that in a dry environment. In the 1980s, the first generation of moisturizing hydrocolloid dressings was born. With the advancement of material science and technology, the new hydrogel d...
