Abstract

The invention relates to a plant polysaccharide protective washing solution taking calcium-modified sodium carboxymethylcellulose as a main component. The plant polysaccharide protective washing solution comprises the following components: 0.3%-3% by weight of calcium-modified sodium carboxymethylcellulose, and 0.01%-0.1% by weight of a pH buffer substance and physiological saline, wherein the pH value of the plant polysaccharide protective washing solution is 6.5-7.5. The plant polysaccharide protective washing solution provided by the invention has the effects of performing surgical flushing, preventing adhesion and promoting wound healing, simultaneously has a hemostatic function and is good in stability and difficult to degrade.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a plant polysaccharide protective flushing liquid used for trauma and surgical flushing. Background technique [0002] Before treating various wounds, the wounds should be rinsed to avoid wound infection. The function of the currently used irrigating fluid is relatively single, which only rinses the wound surface and removes necrotic tissue fragments, foreign objects and bacteria. For example, adding coagulation factors to the flushing solution can speed up the process of hemostasis, which will have very important clinical significance. [0003] Carboxymethylcellulose sodium has the advantages of good bacteriostasis and water solubility, and its aqueous solution has a lubricating function. It is clinically used as a flushing solution for surgical flushing and wound cleaning to prevent surgical adhesions. [0004] The patent application number 200610042240.3 disclose...
