Abstract

The invention relates to chitosan hydrogel used for treating and repairing stoma skin and a preparation method thereof. The chitosan hydrogel is composed of, by weight, 70-90 parts of purified water,5-10 parts of glycerin, 0.5-10 parts of chitosan, 0.5-5 parts of organic acid, 1-10 parts of panthenol, 0.1-5 parts of preservative and 1-10 parts of portylaca oleracea extract. The preparation methodincludes the steps that S1, by total weight, 85-95% of the organic acid in a formula is sufficiently dissolved in the purified water to form acidic liquor, glycerin is dissolved in the acidic liquor,and sufficient homogenizing is conducted; S2, under continuous stirring, chitosan is slowly added into a solution obtained in the first step until dissolving is thorough; S3, the preservation, the portylaca oleracea extract and the panthenol are added into a solution obtained in the second step, and sufficient dissolving is conducted; S4, the remaining 5-15% of organic acid is added into a solution in the third step to adjust the pH of the solution to be 5.0-6.0; S5, materials in the fourth step are separately packaged and subjected to irradiation sterilization. The chitosan hydrogel is goodin treatment effect and can effectively relieve skin inflammation of a patient with a stoma and effectively help the patient to heal when the skin of the patient with the stoma has eruptions.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to a chitosan hydrogel for treating stoma skin and a preparation method thereof. Background technique [0002] The stoma is caused by diseases of the digestive system or urinary system. It is necessary to separate the intestinal tube through surgical treatment, and lead one end of the intestinal tube to the body surface (anus or urethra is moved to the abdominal wall) to form an opening to achieve intestinal decompression, Reduce obstruction, protect the anastomosis or damage of the distal intestine, promote the recovery of intestinal and urinary tract diseases, and even save the patient's life. Stomas are generally for rectal and bladder lesions (such as rectal cancer, bladder cancer, intestinal obstruction, etc.). In order to save the patient's life, the doctor surgically removes the lesion. For example, rectal cancer will remove the rectum and anal canal, and bladder...
