Abstract

The invention provides an antibacterial and healing-promoting foam dressing and its preparation method and application. The foam dressing is mainly prepared from the following raw materials: alginate, methyl gluceth-10, urea and wind extract. The foam dressing alginate of the present invention and windproof extract act synergistically to inhibit the growth and reproduction of bacteria, cooperate with methyl gluceth-10 and urea, and provide a sterile moist microenvironment for the wound surface that is beneficial to wound healing , Excellent hemostatic, anti-inflammatory, healing-promoting and antibacterial effects.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a foam dressing for antibacterial and healing promotion and its preparation method and application. Background technique [0002] Traditional wound dressings include dry gauze and oiled gauze. Dry gauze is used to cover the wound, but its ability to manage exudate is limited. Adhesive wounds may cause re-injury of new epithelial tissue; oil gauze dressings contain petroleum jelly or triglycerides to avoid wound adhesions , but the ability to promote wound healing is poor. Because the liquid secreted by the wound cannot pass through the adhesive plaster layer, traditional wound dressings are likely to cause local skin soaking, making the wound and surrounding skin whiten or even rot. Modern wound dressings avoid the disadvantages of traditional wound dressings to a large extent, not only can protect the wound comprehensively, but also can promote wound healing.
