Abstract
The invention relates to a temperature-sensitive digestive tract injury mucous membrane protective glue, and belongs to the field of biomedical preparations. The digestive tract injury mucous membraneprotective glue comprises a temperature-sensitive biological material, a gelatinization temperature regulator, a biological adhesive and a dissolving solution, wherein the weight percentage ratio ofthe temperature-sensitive biological material to the gelatinization temperature regulator to the biological adhesive is (1-30): (0.5-5): (0.3-5). Under the action of the room temperature (25 DEG C) orbelow, the protective glue is liquid and forms a colloidal film at the body temperature (37 DEG C), so that the irritating effect of intestinal tract digestive juice on injured mucous membranes of digestive tracts is avoided, and the healing of wound surfaces is promoted. Animal tests show that the temperature-sensitive digestive tract injury mucous membrane protective glue can obviously promoterepair of injured mucous membranes, so that the temperature-sensitive digestive tract injury mucous membrane protective glue has the effects of promoting healing and protecting esophagus, stomach andintestinal mucous membrane injuries.
Description
technical field [0001] The invention relates to the technical field of biomedicine, in particular to a temperature-sensitive digestive tract mucosa protective glue suitable for spraying endoscopes on the surface of the damaged mucosa of the digestive tract. Background technique [0002] Gastrointestinal mucosal injury occurs from the esophagus, stomach, duodenum to rectum, some injuries are caused by diseases, and some are caused by surgery. Endoscopic gastric mucosal resection and gastric mucosal dissection are minimally invasive surgeries for the resection of early gastric cancer and benign gastric tumors. They can not only achieve the goal of radically curing early gastric cancer, but also have the advantages of less trauma and less impact on the quality of life of patients. Gradually replace some traditional surgery. Minimally invasive surgery for early cancer and benign tumor resection of esophagus and colon also replaces some traditional surgical operations. However,...
