Gastrointestinal digestive fluid circulation instrument

Abstract

The invention provides a gastrointestinal digestive fluid circulation instrument. The instrument consists of a fluid storage bottle (1), a fluid inlet pipe (2), a fluid outlet pipe (4), a one-way fluid inlet valve (5), a one-way fluid outlet valve (6), a base (7), a suction-propulsion device (8), a bidirectional translation motor (10) and an automatic control device (11), wherein the fluid inlet pipe (2) and the fluid outlet pipe (4) are connected with the upper end and the lower end of the fluid storage bottle (1) respectively; the other end of the fluid outlet pipe (4) is connected with thesuction-propulsion device (8); the suction-propulsion device (8) consists of an outer sleeve (13) and a suction-propulsion rod (14); a pressure sensor (9) is arranged in a tube cavity of the suction-propulsion device (8); the automatic control device (11) controls the bidirectional translation motor (10) to drive the suction-propulsion rod (14) to perform suction or propulsion motion according toa set control program and a command, so a digestive fluid retained at the upper section of an obstruction part can be timely and safely input back to the digestive tract at the lower section of the obstruction part, gastrointestinal digestive fluid circulation is realized, and loss of a large amount of components such as water, electrolytes and proteins is avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to medical equipment for treating diseases of the digestive system, in particular to equipment for circulating gastrointestinal digestive fluid. Background technique [0002] Gastric cancer is a malignant tumor originating from the gastric mucosal epithelium. It ranks first in the incidence of various malignant tumors in my country. There are obvious regional differences in the incidence of gastric cancer. The incidence of gastric cancer in the northwest and eastern coastal areas of my country is significantly higher than that in the southern area. . The age of onset is more than 50 years old, and the ratio of male to female incidence is 2:1. Due to changes in diet structure, increased work pressure, and Helicobacter pylori infection, gastric cancer tends to be younger. Gastric cancer can occur in any part of the stomach, and more than half of them occur in the gastric antrum. The gr...

Problems solved by technology

[0003] The task of the present invention is to provide a gastrointestinal digestive juice circulation instrument, which can realize the digestion of the retention in the upper part of the obstruction part in vitro when the digestive juice such as gastric juice, pancreatic juice, bile and other digestive juices are retained due to various reasons. The digestive fluid in the lower part of the obstruction site can be safely and timely returned to the digestive tract to be absorbed, avoiding a large loss of water, electrolytes, protein and other components, thereby overcoming the cumbersome operation, many steps, and labor-intensive reinfusion of the existing technology. Susceptible to contamination, prone to diarrhea, abdominal pain, fever, septic shock, etc.
