Abstract

The invention provides a bleeding-stopping healing-promoting foam dressing, and a preparation method and application thereof. The method comprises the following steps: (1) mixing and stirring chitosan, frankincense, L-lactic acid oligomer and water; (2) adding a surfactant, a catalyst, a foaming agent and a foam stabilizer, placing the obtained mixture in a foaming mold, and conducting heat preservation, demolding and cutting; (3) conducting immersing in a harba dendrolii nobilis extraction solution, and conducting drying to obtain the foam dressing. The foam dressing prepared by the method ofthe invention adopts an immersing way of immersing in the harba dendrolii nobilis extraction solution, and is simple in process, thus harba dendrolii nobilis is adsorbed for increasing the medicinaleffect of the foam dressing, and also the irritating property of the traditional Chinese medicine extraction solution is avoided. The foam dressing is mild in nature, and has excellent effects of stopping bleeding, diminishing inflammation and promoting healing.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a hemostatic and healing-promoting foam dressing as well as a preparation method and application thereof. 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. [0003] CN ...
