Problems solved by technology

Traditional wound dressings (such as gauze and cotton) have many disadvantages: they are easy to breed bacteria, and the wound exudate is easy to form scabs with dry dermal tissue, which hinders epithelialization; at the same time, the wound is easy to stick to the dressing, causing pain when changing the dressing , causing secondary trauma

Abstract

The invention discloses a medical dressing used for stopping bleeding of traumas. The medical dressing is mainly prepared from the following raw materials in parts by mass: 20-40 parts of polyurethane, 6-10 parts of polyethylene glycol, 1-3 parts of chitosan, 15-20 parts of herb of Japanese thistle, 10-14 parts of aizoon stonecrop herb, 6-12 parts of baikal skullcap root, 5-10 parts of rhizoma corydalis, 7-9 parts of peppermint, 11-13 parts of root of Chinese mahonia, 6-11 parts of incised notopterygium rhizome or root, 5-10 parts of root of littleleaf dogwood, 4-8 parts of cape jasmine fruit and 3-7 parts of fresh cockscomb flower. The medical dressing has the beneficial effects that the medical dressing has excellent properties and good elasticity and toughness, is well fit with wound surfaces, does not adhere to wounds, has good water absorptivity and moisture permeability and keeps the wound surfaces wet; the traditional Chinese medicine ingredients contained in the medical dressing have the activities of clearing away heat and toxic materials and diminishing inflammation and inhibiting bacteria and have the effects of promoting wound healing and preventing infection.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical dressing for trauma hemostasis and a preparation method. Background technique [0002] In recent decades, with the proposal of the "moist healing" theory of wounds and the development of biomaterials, new dressings, especially new polyurethane dressings, have emerged continuously. Traditional wound dressings (such as gauze and cotton) have many disadvantages: they are easy to breed bacteria, and the wound exudate is easy to form scabs with dry dermal tissue, which hinders epithelialization; at the same time, the wound is easy to stick to the dressing, causing pain when the dressing is lifted , causing secondary trauma. The new polyurethane dressing can keep the wound moist and control the water vapor transmission rate. And resist the invasion of bacteria: its spongy porous layered structure is conducive to the discharge of wound secretions. Promote the healing of wou...
