Abstract

The invention relates to a bioactive glass hydrocolloid dressing for promoting wound healing and its preparation method and application. The hydrocolloid dressing is composed of a backing layer, a drug-containing colloid layer and an anti-adhesive layer. Plastic elastomer, tackifying resin, plasticizer, antioxidant, water-absorbing colloid, acid particles, bioactive glass and Sanggenone G, the bioactive glass is composed of Na 2 O, CaO, P 2 o 5 and SiO 2 Composition, the particle size is 40-60μm. The drug-containing bioactive glass hydrocolloid dressing of the present invention has excellent adhesion performance, drug release performance and high water absorption, can greatly enhance the role of the hydrocolloid dressing in promoting wound healing and wound repair, and is convenient to use, good in stability and It has low irritation and is especially suitable for treating chronic ulcerative wounds such as diabetic ulcers, diabetic feet, and decubitus ulcers.

Description

technical field [0001] The invention belongs to the technical field of wound bioactive dressings, and in particular relates to a bioactive glass hydrocolloid dressing for promoting wound healing and its preparation method and application. Background technique [0002] The management of ulcerative wounds plays a vital role in the healing process of chronic ulcerative wounds such as diabetic ulcers, diabetic feet or decubitus ulcers. Current treatments for chronic ulcerative wounds mainly include debridement, skin grafting, vacuum sealing drainage, anti-infection, local active factors, stem cell transplantation, and functional dressing coverage. Appropriate wound dressings can provide a good microenvironment for the wound and promote its healing. Hydrocolloid dressing is a medical material made by uniformly mixing hydrocolloid particles with rubber substrate. The material combines the water-absorbing properties of hydrocolloid particles with the adhesive properties of a rubb...
