Description
Technical Field
The utility model belongs to medical consumptive material field relates to the gauze that disinfects, especially a chitosan quaternary ammonium salt adhesive bandage that disinfects.
Background
The woundplast is one of the most common surgical medicines in human life. The band-aid, also called as hemostatic plaster, has the functions of hemostasis and wound protection. It is made up by using a long adhesive tape and a small piece of yarn soaked with medicine through the middle portion of said adhesive tape.
Due to the structural limitation of the band-aid, the band-aid can only be used for emergency treatment of small wounds, thereby playing the roles of temporary hemostasis and wound surface protection. The band-aid in the prior art has more use problems:
if the adhesive tape is used for a long time, the skin around the wound and the wound is whitened and softened to cause secondary infection of bacteria, so that the wound is further deteriorated. In addition, the wound surface of a patient is accompanied by pain, the existing band-aid can bring friction pain to the patient when contacting the wound surface of the patient, and the use comfort is not good.
Chitosan is a natural cationic basic polysaccharide, chemically known as β - (1-4) -2-amino-2-deoxy-D-glucan, a polymer obtained from the stepwise deacetylation of chitin. Chitin is widely present in organisms such as shells of higher fungi, arthropod shrimps, crabs and insects in the nature, has a very large storage amount on the earth, and is the second largest biological resource in the nature. Chitosan has many biological properties: such as safety, innocuity, anti-tumor, bacteriostasis, biodegradability, biocompatibility and the like. Because the chitosan is a pure natural substance and has very similar biological properties with cellulose and collagen, the chitosan has good biocompatibility with cells and tissues and organs of a human body; has excellent biodegradability, can be completely absorbed in vivo and directly utilized; for damaged tissue cells, chitosan is effective in promoting their regeneration and accelerating healing.
However, chitosan has a large amount of intramolecular and intermolecular hydrogen bonds, so that chitosan is not dissolved in water and dilute alkali solution, is not dissolved in common organic solvent, and is only dissolved in low-concentration inorganic acid acidic solution such as dilute acetic acid and dilute hydrochloric acid (pH <6) and individual organic solvent, so that the application of chitosan in the field of hemostatic dressings is greatly limited.
Through a search of the prior published patent documents, no published patent document similar to the technical features of the patent is found.

The utility model has the advantages that:
1. the cold coating of the chitosan quaternary ammonium salt dressing bag is prepared by taking a high-molecular hydrogel material as a matrix, contains natural cool traditional Chinese medicine components, takes away heat after contacting air for vaporization, and can achieve the effect of local cooling, and the medicine can quickly penetrate through a fat layer through the medicine components after the hydrogel is combined, and then permeates into subcutaneous tissues to directly reach focuses, so that the effects and effects of cold compress pain relief, percutaneous absorption and sustained release administration are achieved.
2. The iodophor layer of the chitosan quaternary ammonium salt dressing bag is composed of a plurality of unit gel balls filled with iodophor liquid, the matrix of the iodophor layer is gel, the iodophor liquid in the unit gel layer is released to achieve the effects of disinfecting and sterilizing wounds and improving the use comfort, and the sterilization effect of the chitosan quaternary ammonium salt sterilization layer can be promoted.
3. The water absorbing layer of the chitosan quaternary ammonium salt dressing bag mainly absorbs redundant moisture, the adhesive tape can keep dry and comfortable in the long-time use process of the adhesive tape, the adhesive tape on the outer layer of the adhesive tape is not breathable, so that a wound and skin around the wound are whitened, the skin is softened to cause secondary infection of bacteria, and the wound can be further deteriorated.
4. The chitosan quaternary ammonium salt adopted in the chitosan quaternary ammonium salt dressing bag is 2-hydroxypropyl trimethyl ammonium chloride chitosan, the chitosan quaternary ammonium salt dressing bag is prepared by chemically modifying chitosan, the water solubility is good, the application range of the chitosan is enlarged, the used 2-hydroxypropyl trimethyl ammonium chloride chitosan not only plays the advantages of wide chitosan source and the like, but also mainly inherits the sterilization characteristic of the chitosan, can be well combined with common gauze, effectively reduces the infection rate of wounds and promotes healing.
5. The utility model discloses newly use chitosan quaternary ammonium salt dressing package in the band-aid, and increased iodophor layer and cold coating, use comfortable softness, have good ventilative moisture absorption, detumescence, hemostasis function, and nontoxic, tasteless, no stimulation, no corruption, pollution-free, belong to the medical product of environment-friendly type.
