Stomach fluid director and releasing method thereof

Abstract

The invention discloses a stomach fluid director and a releasing method thereof. The stomach fluid director comprises a storage tube shell, a releasing body and a pushing assembly, a gastrointestinalstent has an unexpanded shape and an expanded shape, the gastrointestinal stent comprises an upper stent, a lower stent and connecting pieces; under the expanded shape, the lower stent is arranged under the upper stent, the upper stent and the lower stent are connected through the connecting pieces, a fourth opening of the lower stent is connected with a membrane tube, the expanded upper stent andlower stent both cannot pass through a stomach pyloric opening, and the connecting pieces can pass through the stomach pyloric opening or penetrate through the stomach pyloric opening. In this way, the gastrointestinal stent is divided into two parts to be fixed, one part is fixed in the stomach pyloric opening, the upper end of the membrane tube is firmly positioned in the alimentary canal during peristalsis of the alimentary canal, the other part is fixed to the duodenal bulb, and during antiperistalsis of the alimentary canal, the lower section of extending membrane tube returns into the stomach very easily to cause that food does not flow according to a designed channel.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric deflector for treating endocrine diseases (such as diabetes, pancreatic islet dysfunction, obesity, etc.) or lower digestive tract diseases (such as inflammation, etc.) and a release method thereof. 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 ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned intragastric device has the following problems: one is that the memory alloy material with self-expanding shape has certain mechanical force and weight. It will compress the gastric mucosa in the stomach, which is very easy to cause peptic ulcer; second, the food stays in the balloon for a long time, although it can slow down the emptying of the stomach, it is easy to cause bacterial growth and cause inflammation; third, The device is not fixed in the pyloric orifice or the duodenal bulb, and the extended membrane tube at the lower part is very easy to return to the stomach due to the reverse peristalsis of the digestive tract, causing food to not flow according to the designed channel; Large, especially after the content of food, the foreign body sensation in the pylorus is obvious and it is easy to cause symptoms such as lax closure of the pylorus and bile reflux

The stent is used for the treatment of stenosis or obstruction of the digestive tract, which can expand and support the stenosis. It is generally implanted in the digestive tract as an independent product without connecting the membrane tube. Because of its high support strength and not easy to deform, it is Cannot be used in the pyloric opening of the stomach and cannot be used as a gastric diverter
