Medical protecting irrigation solution and preparation method thereof

Abstract

The invention relates to a medical protecting irrigation solution. The irrigation solution comprises the following components in percentage by weight: 0.5-5 percent of carboxymethyl chitosan, 0.70-0.9 percent of sodium chloride and the balance of water, wherein the weight-average molecular weight of the carboxymethyl chitosan is 5000-80000. The medical protecting irrigation solution can play roles in irrigating and cleaning a traumatic wound, and has the effects of keeping the wound wet and smooth, preventing adhesion of a wound and generation of a scar, inhibiting bacteria on the wound from growing, and the like; furthermore, the process is simple, and the irrigation solution can be stored stably and has less possibility of being degraded.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a medical flushing liquid and a preparation method thereof. Background technique [0002] Due to the mechanized industrial age, injuries caused by various accidents are increasing day by day. How to better promote wound healing of patients and reduce their pain is the direction of many people's efforts. [0003] In the process of surgical trauma treatment, medical workers often use various measures to deal with it, such as hemostatic agents, anti-inflammatory agents, wound rinses, etc. Currently, the commonly used medical rinse solution is sodium chloride injection, which has good fluidity , clean and pollution-free, which is of great significance for debridement during surgery. [0004] However, sodium chloride injection still has some deficiencies as a medical flushing solution. For example, no moisturizing properties, no lubricating properties, and no antibacterial...

Problems solved by technology

[0011] However, it is well known that a humid environment is often accompanied by aggravation of bacterial infection. Bacteria are more likely to survive and reproduce in a humid environment, and the ability of bacteria to survive and reproduce in a dry environment is greatly reduced.

[0012] Therefore, the moisturizing, lubricating and antibacterial effects of the irrigation solution are also aspects that clinical medical staff are very concerned about, but the research on the irrigation solution in the prior art has not yet involved these aspects, especially in the surgical wound irrigation. , lubricating, antibacterial, and healing-promoting protective douches have not been reported
