Problems solved by technology

The risk of this design is that the barb penetrates the duodenum, which will cause certain damage to the human digestive tract. When the barb is taken out, it will easily damage the esophagus and cause the esophagus to tear
If the catheter accidentally falls into the distal duodenum, jejunum, or even colon, it is easy to cause intestinal obstruction

Abstract

The invention discloses a gastric fluid director and a support thereof. The support is a reticulated tube formed by weaving woven wires, and comprises an upper support section and a lower support section, wherein the outer diameter of the upper support section is larger than that of the lower support section. The support can provide good support force and is fixed at the duodenum. The support has good compliance and fatigue resistance, has certain support force and certain flexibility, and can be stably fixed at the duodenum for a long time; the support can move along with the movement of the duodenum, but does not damage the wall of the duodenum. Furthermore, the support can be connected with a duodenal membrane tube so as to be used for treating metabolic diseases such as diabetes mellitus and obesity. The support is good in applicability, convenient in manufacturing technology, low in cost and rapid in production speed, and is used for the digestive tract; the support also can be connected with an implanted catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric deflector and a digestive tract stent for treating endocrine diseases (such as diabetes, pancreatic islet dysfunction, obesity, etc.) or lower digestive tract diseases (such as inflammation, etc.). Background technique [0002] It is known that diabetes is a disease that has gradually been paid attention to by people in recent years. It is one of the diseases of the rich and the rich. It is derived from the continuous improvement of living standards in modern civilized society. , overnutrition, reduced activity, resulting in a non-infectious epidemic, specifically, diabetes refers to a metabolic disease characterized by high blood sugar. It results from defective insulin secretion or impaired biological action, or both. Diabetes can lead to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves. Diabetes i...
