Problems solved by technology

[0007] Chlorhexidine decolonization is currently done by bathing or scrubbing, but this method of decolonization has disadvantages: 1. It is not conducive to the operation of medical staff; 2. It takes a long time to operate; 3. The patient feels bad; 4. Decolonization The colonization time is short, and the decolonization effect cannot be maintained for a long time; according to the implementation of the present invention, hyaluronic acid thermosensitive gel is used as a general decolonization measure, and the composition of the present invention solves the problems existing in the existing chlorhexidine decolonization

Abstract

The invention discloses hyaluronic temperature-sensitive gel and a preparation method and application thereof. The hyaluronic temperature-sensitive gel comprises, by mass, 0.01-0.3% of medium-molecular-weight hyaluronic acid, 0.01-0.5% of small-molecular-weight hyaluronic acid, 0.05-2% of chlorhexidine, 8-25% of poloxamer 407, 0.1-1% of hydroxypropyl methylcellulose, 0.05-0.5% of hydroxyethyl cellulose, 0.1-1% of polyethylene glycol, 0.1-1.0% of glycerol, 0.01-0.2% of pentanediol, 0.01-0.1% of octanediol and the balance of water. The hyaluronic temperature-sensitive gel has efficacy of moisturizing, repairing and sterilizing, can form a protecting film on the surface of skin or damaged skin and is suitable for body surface de-planting and sterilization nursing and sterile maintaining of barrier damaged skin of skin trauma and postoperative wound surface of inpatients.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a hyaluronic acid temperature-sensitive gel and a preparation method and application thereof. Background technique [0002] Hyaluronic acid (HA), namely sodium hyaluronate, is a linear polysaccharide composed of repeating disaccharide units of β-D-N-acetylglucosamine and β-D-glucuronic acid bonded alternately. The molecules of hyaluronic acid can carry more than 500 times of water, can maintain the water in the extracellular matrix, promote cell migration and differentiation, have very excellent biocompatibility, and are recognized as the best moisturizing ingredients today, and are widely used In skin care products and cosmetics. [0003] Wound healing of human skin and mucous membranes is a process involving the reconstruction and regeneration of extracellular matrix by various cells and their secreted products. Maintaining the humidity of the wound surface has a very obvious promotin...
