Skin wound inorganic functional dressing capable of stopping bleeding and promoting healing and preparation method of skin wound inorganic functional dressing

Abstract

The invention provides a skin wound inorganic functional dressing capable of stopping bleeding and promoting healing and a preparation method of the skin wound inorganic functional dressing. The skin wound inorganic functional dressing is prepared from, by weight, 10-25 parts of modified bioactive glass, 12-32 parts of tetrafluoroethane, 3-10 parts of chitosan, 2-6 parts of sodium alginate, 3-7 parts of polyoxyethylene, 8-20 parts of rice bran extracting solution, 2-4 parts of laurocapram, 1-3 parts of menthol and 4-10 parts of konjac glucomannan. According to the dressing, raw materials are reasonably screened, modified bioactive glass and small molecular chitosan are added as antibacterial agents, water-soluble high-molecular polymers such as sodium alginate, polyethylene oxide and a rice bran extracting solution are added, laurocapram, menthol and natural gel konjac glucomannan are combined, and all the raw materials are scientifically proportioned and synergistically play a role; the prepared skin wound inorganic functional dressing has excellent effects of stopping bleeding, neutralizing exudation, inducing epithelial regeneration to promote healing and reducing scars, and has good biocompatibility.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a hemostatic and healing-promoting inorganic functional dressing for skin wounds and a preparation method thereof. Background technique [0002] The skin is the largest organ of the human body, and it is a natural barrier to maintain the stability of the internal environment and prevent the invasion of microorganisms; however, the large area exposed to the outside world makes the skin vulnerable to external injuries such as burns and mechanical injuries, which will cause many local and even systemic diseases. Sexual problems, such as increased metabolism, excessive loss of water and protein, immune system disorders, etc., can even be life-threatening if serious. If the wound is covered with an appropriate dressing, it can effectively reduce the severity of hypermetabolism in the patient's body, relieve pain, prevent bacterial infection, and accelerate wound healing.
