Abstract

The invention discloses a process for preparing a high-permeability antibacterial wound dressing by jet cavitation, and belongs to the technical field of novel polysaccharide-alkaloid processing. Theprocess comprises the following specific steps: (1) preparing a capsaicin-chitosan solution; (2) preparing a chitosan-capsaicin compound membrane preparation liquid; (3) preparing a chitosan-capsaicincompound membrane stock solution; and (4) performing mould reversing and drying to obtain a finished product. The method takes chitosan as a raw material, applies alkaloid and capsaicin to membrane production for the first time, and treats the chitosan-capsaicin compound membrane preparation liquid by using a jet cavitation technology to prepare the high-permeability and antibacterial compound membrane product. The product has good biocompatibility, regenerability and degradability, and accords with the sustainable development concept of environmental protection and saving.

Description

[0001] The invention belongs to the technical field of novel polysaccharide-plant alkaloid processing, and mainly relates to a process for preparing highly air-permeable antibacterial wound dressing by jet cavitation. Background technique [0002] A wound dressing is a wound dressing, a material used to cover a sore, wound or other damage. The types of wound dressings are: 1. Passive dressings (traditional dressings), which passively cover the wound and absorb exudate, providing limited protection for the wound; 2. Interactive dressings, there are various forms between the dressing and the wound. Interactions, such as absorbing exudate and toxic substances, allowing gas exchange, thereby creating an ideal environment for healing, barrier outer structure, preventing microbial invasion in the environment, preventing cross-infection of wounds, etc.; 3. Bioactive dressings ( occlusive dressing). However, the current commercially available wound dressings generally have the disadv...
