Abstract

The invention belongs to the field of medical dressings, and particularly relates to a waterproof liquid wound dressing. The waterproof liquid wound dressing comprises a film-forming agent material, askin adhesion material, a plasticizer, a film-forming synergist, an antibacterial agent and a solvent. The invention also relates to a preparation method of the waterproof liquid wound dressing and an application of the waterproof liquid wound dressing in the preparation of medical supplies for promoting wound healing. The waterproof wound dressing is high in film forming speed, good in waterproof performance, good in flexure resistance and good in air permeability, and can effectively inhibit bacteria, and all the components have a synergistic interaction effect in the aspects of waterproofperformance, flexure resistance and air permeability.

Description

technical field [0001] The invention belongs to the field of medical dressings, and in particular relates to a waterproof liquid wound dressing, a preparation method thereof and an application for preparing medical supplies for promoting wound healing. Background technique [0002] Small wounds on the body surface caused by abrasions, cuts, lacerations and minor burns are very common in people's daily life. [0003] Band-aids are commonly used to treat such wounds at present. Traditional Band-Aids can compress and stop bleeding, protect wounds, prevent infection, and promote healing. At the same time, they have the advantages of small size, easy use, and portability. However, the adhesive plaster used has poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive plaster, so it has a soaking effect on the local skin, which is specifically manifested as local skin folds. [0004] Liquid Band-Aids have the...
