Abstract

The invention relates to the technical field of medical supplies, and in particular relates to a hydrocolloid dressing with strong antibacterial capacity and a preparation method of the hydrocolloid dressing. The hydrocolloid dressing is prepared from the following raw materials in parts by weight: 35-55 parts of sodium carboxymethyl cellulose, 30-50 parts of carboxymethyl chitosan, 20-40 parts ofpolyurethane thermoplastic elastomers, 10-35 parts of sodium alginate, 5-20 parts of tackifying resin, 1-10 parts of a plasticizer, 10-15 parts of gelatin, 3-8 parts of alkyl starch ester, 1-7 partsof polyisobutene, 0.5-3.2 parts of an antioxidant, 0.5-4.5 parts of a fungicide, and 0.5-2.5 parts of a synergistic fungicide. For the prepared hydrocolloid dressing, the potential biosecurity risk ofthe product is reduced, the antibacterial rate of the product is improved, a moist heal environment is provided for the wound, meanwhile, the heal of the surface of the wound is also promoted, the hydrocolloid dressing provided by the invention has good autohension and elasticity, and can be softly applied to the surface of the skin, and a user feels comfortable.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a hydrocolloid dressing with strong antibacterial ability and a preparation method thereof. Background technique [0002] Hydrocolloid dressing is a medical dressing made by blending water-absorbing polymer particles with hot-melt pressure-sensitive adhesive. This material combines the adhesive properties of rubber materials and the water-absorbing properties of water-absorbing polymer materials. Rubber The base material provides viscosity, which enables the dressing to stick to the wound surface, and the hydrocolloid particles dispersed in it swell after washing, providing a moist sealing environment for the wound and promoting wound healing. A moist environment plays an important role in wound healing The promotion effect brings great convenience to wound care. However, chronic wounds are skin tissue damages caused by external force factors such as surgery and heat. O...
