Intestinal content autologous reinfusion device and usage method after small bowel double-cavity ostomy

Abstract

The invention discloses an autologous transfusion device of intestine contents after small intestine double-cavity coloproctia operation. The autologous transfusion device comprises an autologous transfusion device body which penetrates into a small intestine; the autologous transfusion device body comprises a pipe body made of an elastic material; a drop-proof air bag fixedly sleeves the external circumference of each of parts, close to two ends, of the pipe body; a plurality of annular first elastic bags and second elastic bags, which are fixed on an inner pipe wall, are arranged on the inner pipe wall of the pipe body along the axial direction; check valves are arranged between the first elastic bags and the second elastic bags; first connecting pipes penetrate into the first elastic bags; the first connecting pipes are provided with first branch pipes in cavities of the first elastic bags; second connecting pipes penetrate into the second elastic bags; the second connecting pipes are provided with second branch pipes in cavities of the second elastic bags. The autologous transfusion device disclosed by the invention has the following advantage that small intestine fluid, which is lost at a rear-end small intestine anastomosis and comprises digestive fluid and nutrient substances, can be recycled; and a far-end small intestine and colorectum recover functions as soon as possible and the atrophy of intestinal glands is reduced.

Description

technical field [0001] The invention relates to the field of intestinal artificial aids after small enterostomy, in particular to a device for autologous reinfusion of intestinal contents after small enterostomy and a method of use. Background technique [0002] Due to small bowel damage caused by trauma and intraoperative operation, and diffuse peritonitis, it is difficult to perform primary intestinal resection and intestinal anastomosis. In order to save life and other therapeutic needs, double-chamber jejunostomy is performed. For more than 3 months after surgery. As a very important organ of digestion and absorption in the digestive tract, the small intestine is the longest part of the digestive tract. After digestion in the small intestine, the food in the small intestine is decomposed into small molecular substances that can be absorbed. However, during this period, although the patient can eat, most of the nutrients in the food and various digestive juices (pancreat...

AI Technical Summary

Problems solved by technology

However, during this period, although the patient can eat, most of the nutrients in the food and various digestive juices (pancreatic juice, bile, small intestinal juice, etc.) are lost through the small enterostomy

Therefore, a large amount of small intestinal content often flows out of the stoma, leading to water, electrolyte, acid-base balance disorders, malnutrition, erosive dermatitis of the stoma, etc., and also causes great mental and psychological pressure to the patient
