Problems solved by technology

[0004] However, a simple wet environment can no longer meet the various needs of skin repair. Traditional wet materials have many shortcomings, such as: poor water permeability and air permeability; more heat and electrolyte loss; antigenicity; unable to meet skin collagen growth and Growth factor growth and many other requirements, etc.

Abstract

The invention provides dressing with a synergistic effect with skin. The dressing is characterized by comprising the following raw materials in percentage by mass: 0.03-0.5% of hyaluronic acid, 0.09-0.5% of collagen, 0.01-0.05% of epidermi growth factor, 0.1-0.5% of sodium hydroxide, 1.5-3.0% of EDTA (Ethylene Diamine Tetraacetic Acid) disodium and the balance of water. Due to adoption of the dressing, a better micro environment can be provided, the nutrient components can be replenished, and the rapid and non-spot self-healing of skin is promoted.

Description

technical field [0001] The invention relates to the field of dressings, and mainly relates to a dressing that works synergistically with the skin and a preparation and application method thereof. Background technique [0002] Bacterial infection is one of the main factors that affect wound healing. A large number of inflammatory factors, proteases and free radicals contained in wound exudate will slow down wound healing. Currently, wound care products mainly include two parts: traditional dressings that provide a dry healing environment and high-end dressings that provide a moist healing environment. Since the British scholar Winter proposed that wounds heal faster in a humid environment than in a dry environment, people have a new understanding of the process of wound healing. Compared with traditional dressings that have many disadvantages, high-end dressings not only have no The disadvantages described below are widely accepted as an effective way to speed up healing. ...
