Problems solved by technology

However, the liquid dressing itself has poor water resistance and cannot form a complete closed screen. The antibacterial effect is poor and it is easy to cause wound infection. In addition, most of them use alcohol as a solvent, which is not gentle enough when used, and has certain irritation to the wound.

Abstract

The invention provides an antibacterial liquid medical dressing and a preparation method thereof. The medical dressing is prepared from the following raw materials: silk fibroin, thiolated chitosan, potassium alginate, glycine fumarate, povidone iodine, artemisinin extract, pongamia pinnata isoflavones, polyvinylpyrrolidone, sodium D-glucuronate, flaxseed gum, lithium carbonate, lanthanum phosphate, dry earthworm powder, triglycidyl isocyanurate, charantin, behenic acid, glycerin and acetic acid. According to the liquid medical dressing prepared with the method, the inhibition rate of pseudomonas aeruginosa and staphylococcus aureus is higher than 99%, the healing time is short and only reaches 5-9 days, the healing effect is good, no scars are generated, the patient experience is good, and no phenomena of stabbing pain, pruritus and allergy are caused. The liquid medical dressing prepared with the method is high in bacterial inhibition rate, shortened in healing time, more convenient to use, free from limitation of a wound part, convenient to carry and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a bacteriostatic liquid medical dressing and a preparation method thereof. Background technique [0002] Common injuries to human skin mainly include burns, scalds, acute or chronic ulcers, and surgical wounds. After a large area of ​​skin is injured, it is easy to be infected by bacteria, loss of body fluids and various complications. In severe cases, it can lead to increased metabolism, decreased body temperature, excessive loss of water and protein, and disorders of the endocrine and immune systems, etc., and even endanger the skin. Life, these are all related to the loss of skin barrier function. [0003] Medical dressings are an important class of medical materials used to cover sores, wounds or other injuries. It can provide a physical shield for the wound, control the fluid produced by the wound, absorb pus and blood from wet wounds, and provide mois...
