Problems solved by technology

In this method, because the plant fiber gauze (such as cotton gauze) is easy to adhere to the wound site, it causes repeated damage to the skin while changing the dressing.
At the same time, plant fiber gauze itself has no antibacterial properties and needs to be manually disinfected before taking the medicine; it has poor biocompatibility and degradability and must be removed

Embodiment Construction

[0008] The medical dressing proposed by the present invention contains quasi-cationic (amino-containing) water-soluble chitin derivatives, and can also be compounded with drugs that can promote epidermal growth or / and tissue recovery or / and other fillers such as antibacterial and anti-inflammatory drugs , And add pure water. It can be an aqueous solution or made into a thin-film product.

[0009] Whether it is an aqueous solution or a film-type product, the quasi-cationic water-soluble chitin derivative accounts for 5%-100% by weight of the total solids, and the rest are fillers or compound drugs. The filler can be a harmless substance such as starch, or it can be a compound drug itself. Compound drugs can choose drugs that can enhance their effects, such as beta-interferon with antiviral effects, and epidermal growth factor gold peptides that can promote skin growth.

[0010] The quasi-cationic water-soluble chitin derivative is a water-soluble chitin derivative with an amino gro...

Abstract

The medical dressing consists of solid component and water, and features that the solid component contains quasi-cationic water soluble chitin derivative in 5-100 wt%. The production process of the medical dressing is to dissolve quasi-cationic water soluble chitin derivative in pure water to form water solution. Owing to that the quasi-cationic water soluble chitin derivative is water soluble, water maintainable, antibiotic, biocompatible and biodegradable and can promote heal of wound, it is easy to change without adhesion, less likely to form scar, high in antiseptic and antiphlogistic effect and high in promoting heal. The medical dressing has obvious curative effect on cut, burn and scald wound, traumatic wound, external ulcer surface, etc.

Description

Technical field: [0001] The invention relates to a medical dressing and a production method thereof, in particular to a medical dressing for treating skin injuries and a production method thereof. Background technique: [0002] At present, the medical field usually uses plant fiber gauze (such as cotton gauze) as a drug delivery carrier to treat skin injuries, and then apply the medicine to cover the wound surface. In this method, plant fiber gauze (such as cotton gauze) is easy to adhere to the wound site, causing repeated damage to the skin while changing the dressing. At the same time, the plant fiber gauze itself does not have antibacterial properties and needs to be manually disinfected before applying the medicine; the biocompatibility and degradability are poor, and it must be removed. Summary of the invention: [0003] The purpose of the present invention is to solve the above problems and provide a medical dressing and a production method thereof, which can significantl...
