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

Abstract

The invention provides a liquid dressing for a wound. The liquid dressing is used for cleaning the wound in the wound cleaning process and being applied to the surface of the wound when a dressing is changed for the wound. The liquid dressing for the wound mainly comprises polyhexamethylene biguanidine hydrochloride and cocamidopropyl betaine, wherein the content of polyhexamethylene biguanidine hydrochloride is 0.05-0.5% g / ml, the content of cocamidopropyl betaine is 0.05-0.5% g / ml, and the balance is water. The liquid dressing is low in toxicity, good in tolerance, free of irritation, high in antibacterial activity and further has the effects of alleviating pain, reducing peculiar smell of the wound and promoting healing of the wound.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a liquid 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. The wound cleaning agent used in the debridement process and the liquid wound dressing used in dressing changes are all called liquid trauma wound dressings. [0003] At present, liquid trauma wound dressings are widely used. This type of dressing can keep the wound in a moist environment, sterilize and inhibit bacteria, and can effectively promote the growth of granulation tissue and promote wound healing. At present, there are several kinds of liquid wound dressings widely used i...
