Abstract

The invention relates to a nano-silver foaming agent used for sterilizing wounds of scalds and burns and ulcer wounds. The nano-silver foaming agent is prepared from antibacterial material nano-silver and chitosan as main components and a solubilizing agent, a wetting agent, a thickening agent, potential of hydrogen (pH) value regulator, a foaming agent and a preservative as auxiliary materials through adding bacteriocidal substance borneol and cool substance menthol crystal. A preparation method for the nano-silver foaming agent comprises the following steps of: evenly mixing all components; then, performing ultrasonic homogenizing for 30 minutes to prepare a solution; then, filling the solution into a pressure bottle; adding a propellant to prepare nano-silver foaming agent finished product (50-100nm) used for sterilizing the wounds of the scalds and burns and the ulcer wounds. The product is good in sterilizing effect, is safe and reliable, is free of skin irritation and can be used for promoting the healing of the wounds. The process is simple and feasible, and the product is convenient to use and remarkable in effect.

Description

technical field [0001] The invention relates to a foam agent used for disinfection of burns and ulcer wounds, in particular to a foam agent using nano-silver and chitosan as bactericidal substances, and belongs to the technical field of medical disinfectant production. Background technique [0002] Wounds can be seen everywhere in life, and often cause skin and soft tissue damage. Once caused, it will bring a lot of inconvenience to people's life and work, and even threaten human health. In order to keep the wound from infection and heal faster, the wound must be disinfected first. Commonly used disinfectants include iodine, alcohol, hydrogen peroxide, etc., but these substances are relatively irritating and should be avoided in large doses, especially suppurative Sexual wounds, purulent secretions, and fat inside the wound react with iodine to form compounds that render it ineffective. [0003] The antibacterial properties of silver have been widely used in the medical fie...
