Description

Chitosan sterilization dressing plaster

Technical Field

The utility model relates to the field of medical supplies, specifically speaking, in particular to chitosan dressing subsides that disinfect.

Background

Chitosan is a product of removing partial acetyl of natural polysaccharide chitin, has multiple physiological functions of biodegradability, biocompatibility, nontoxicity, bacteriostasis, cancer resistance, lipid reduction, immunity enhancement and the like, and is widely applied to various fields of food additives, textiles, agriculture, environmental protection, beauty and health care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials, drug slow release materials, gene transduction carriers, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical treatment, drug development and the like and other daily chemical industries. The chitosan has good inhibition effect on Escherichia coli, pseudomonas fluorescens, staphylococcus aureus, bacillus subtilis, etc., and can inhibit physiological change of fresh food. The chitosan is natural and nontoxic, is suitable for keeping acidic food with less protein, and can agglutinate when meeting high polymer and ionic compound. The chitosan is used as a drug carrier, so that the components in the drug can be stabilized, the drug absorption is promoted, the dissolution speed of the drug is delayed or controlled, the drug is helped to reach a target organ, the acid resistance and the ulcer resistance are realized, and the stimulation of the drug to the stomach is prevented. The chitosan can be used for preparing microspheres, and the prepared microspheres have good adhesiveness and are relatively suitable for oral, nasal, gastrointestinal and other mucosal administration; the surface of the chitosan microsphere is rich in polysaccharide chains, can be identified by specific cells or tissues, and can deliver drugs to focus sites in a targeted manner for storage and release; the surface of the chitosan microsphere can be connected with functional groups to flexibly load different drugs in an adsorption or wrapping manner. The chitosan is natural hydrophilic macromolecule, and can form hydrogel through certain chemical crosslinking or physical crosslinking. The cold compress treatment effect can be achieved through the physical action of the effective components such as menthol and the like and the hydrogel. Can reduce joint tissue damage, eliminate swelling and pain, and reduce inflammation complications.

The common dressing has poor air permeability, certain anaerobic bacteria can possibly obtain the opportunity of propagation, such as common tetanus bacillus, wounds are difficult to heal (cells at the wounds can make a series of reactions after being stimulated by air, such as surface cells are necrotized and scabbed, and internal cells are proliferated to accelerate tissue healing), and people also can deteriorate the wounds. If the medicine is directly smeared on the wound, the medicine is easy to rub on the wound in daily activities, and secondary damage is caused to the wound.
