Description

Digestive juice back-transfusion device

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to digestive juice feedback device.

Background

In recent years, the incidence of acute severe pancreatitis (SAP) is gradually increased, the condition is critical and rapidly developed, the death rate is up to 20-30%, and the prognosis is very poor. Gastroparesis is a syndrome of gastric motility disorder caused by non-mechanical obstruction, and is mainly manifested as gastric emptying disorder. The incidence of gastroparesis and digestive fistula also shows a tendency to rise year by year due to the continuous development of surgical operations. The back infusion of digestive juice is not only a treatment means of modern surgical treatment, but also one of the methods for preventing SAP serious complications and reducing disability rate and mortality rate. The back transfusion of digestive juice can supplement body fluid and electrolyte loss, effectively prevent electrolyte disorder caused by fasting, diarrhea or digestive tract fistula, supplement digestive enzyme required by nutrient absorption of patients, promote nutrient absorption, prevent small intestine atrophy, increase small intestine protein and DNA content, promote cell division and proliferation, and facilitate intestinal canal separation and anastomosis during operation. Meanwhile, the digestive juice can be recovered to circulate in the gastrointestinal tract by the back transfusion of the digestive juice, and the relative continuity and integrity of the gastrointestinal tract are maintained, so that the loss of digestive enzymes and the occurrence of water and electrolyte disorder and complications are reduced.

At present, a disposable negative pressure aspirator and a disposable drainage bag are clinically adopted, the negative pressure aspirator is mainly used for collecting gastric juice of patients with acute pancreatitis, and the drainage bag is mainly applied to gastroparesis, digestive tract fistula or other patients needing to collect gastric juice. The two products are only used for collecting digestive juice, and the operation process from collecting to returning all the digestive juice is complicated. In the conventional operation, the collected digestive juice needs to be stood for 2-3 hours at normal temperature, then is filtered into a sterile dressing change bowl or a disposable dressing change bowl by double-layer gauze, is extracted by an injector, is connected with a three-way pipe and then is infused with nutrient solution at the same time. The process has the defects of inconvenient operation, easy pollution, incomplete gastric juice filtration, easy pipeline blockage caused by impurities and the like.

In order to solve the problems that gastric juice is not thoroughly filtered and impurities easily block pipelines, Chinese patent CN206526318U discloses a disposable digestive juice feedback device, and a filtering form is carried out by adding a filtering net into an original bag body.
