Gel state traumatic wound dressings

Abstract

The invention provides gel state traumatic wound dressings which are mainly prepared from, by mass, 0.05-0.5% of polyhexamethylene biguanidine hydrochloride, 0.05-0.5% of cocamidopropyl betaine and 2-5% of gels, wherein water serves as solvent.The gel state traumatic wound dressings are low in toxicity, good in tolerance, free of irritation and high in antimicrobial activity and can further have the effects of relieving pain, lowering peculiar smell of a wound and promoting wound healing.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a gel state wound dressing for external wounds. Background technique [0002] Skin and soft tissue wounds such as open wounds, soft tissue infection ulcers, and surgical incisions require wound treatment to ensure that the wound is clean and sterile, promote the growth of granulation, and promote wound healing. For the treatment of the above wounds, debridement and dressing changes are generally required. Gel state dressings used during dressing changes are generally referred to as gel state external trauma wound dressings. [0003] At present, gel wound dressings are widely used.

Tissue growth, promoting wound healing. The widely used wound dressin...

AI Technical Summary

Problems solved by technology

However, the current chemical sterilants mainly have the following problems: first, most of the chemical preparations are irritating to a certain extent, which will increase the patient's pain, and some patients will also have allergic reactions; secondly, most of the chemical preparations are harmful to soft tissues. The exudate has no inhibitory and treatment effects, and the use of such dressings has a strong odor; finally, chemical preparations generally lack the effect of promoting the growth of granulation tissue, and cannot make the wound heal quickly

Gel sponge dressings are mainly used for wound drainage and need to be used with negative pressure. The application range is narrow and the price is very expensive.
