Description
Technical field
The utility model relates to the field of medical instrument technology, especially it is a kind of for treat endocrine system disease (such as diabetes,
Islet function disorder, obesity etc.) or disease of lower digestive tract (such as inflammation) antibacterial alimentary canal membrane tube.
Background technique
It is known that diabetes are a kind of diseases being gradually valued by the people in recent years, it is one of rich people's disease, is source
It is continuously improved in the living standard of modern civilization society, after people's lives are rich, eat good things, eats smart, overnutrition, activity
Amount is reduced, thus the non-infectious epidemic disease generated, specifically, diabetes refer to the metabolic disease characterized by hyperglycemia
Disease.It is since defect of insulin secretion or its biological effect are impaired, or both have concurrently caused by.Diabetes can cause various
Tissue, especially eye, kidney, heart, blood vessel, the chronic lesion of nerve, dysfunction.Diabetes are usually along with fat and very
More complication cause greatly to threaten to people's health.Data are shown, only Chinese, in 20 years old or more adult, glycosuria
The disease incidence of disease is 9.7%, population about 1.5 hundred million of falling ill.It is known that it is to keep on a diet that common obesity and diabetes, which improve mode,
Increase movement, and assist certain drug therapy, this needs adhering to for a long time for patient, and once stops diet control and movement
After easily cause repeatedly and weight gain, the use of long-term drug or insulin also brings heavy financial burden to patient
With the inconvenience of life.
Another cure is Gastric bypass, is had very using Gastric bypass for radical cure type-II diabetes and improvement obesity
Good effect, in 2001, formal recommendation was metabolized surgical operation (including the operation of stomach turn of tidal stream) conduct to International Diabetes Federation
Obesity merges the treatment method of type-II diabetes, however Gastric bypass can cause wound to human body as a kind of surgical operation, because
This with many risks such as: death, intestinal obstruction, anastomotic leakage, pulmonary embolism, deep vein thrombosis, injury of portal vein, respiratory system
Deng.
The patent document of Publication No. CN106923944A discloses a kind of enteron aisle isolation membrane tube release, including tubular shell
