Abstract
The invention relates to a bioactive glass hydrocolloid dressing for promoting wound healing and a preparation method and application thereof. The hydrocolloid dressing consists of a backing layer, a drug-containing colloid layer and an anti-sticking layer; the drug-containing colloid layer consists of a thermoplastic elastomer, tackifying resin, a plasticizer, an antioxidant, a water-absorbent colloid, acidic particles, bioactive glass and sanggenone G; and the bioactive glass consists of Na2O, CaO, P2O5 and SiO2, and the particle size is 40-60 [mu]m. The drug-containing bioactive glass hydrocolloid dressing of the invention has excellent adhesion performance, drug release performance and high water absorption capacity; the function of promoting wound healing and wound repair of the hydrocolloid dressing can be greatly enhanced; and the dressing is convenient to use, high in stability, low in irritation, and is especially suitable for treating chronic ulcerative wounds such as diabetic ulcers, diabetic feet and bedsores.
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...
