Problems solved by technology

[0008] Aiming at the above-mentioned problems in the prior art, the inventors of the present invention have found through careful research that polyethylene materials can be used as the material for making large-diameter thin-walled catheters, which can fully overcome the high cost and high hardness of existing implantable catheters. Problem, at the same time, the inventor used different proportions of high-density polyethylene and low-density polyethylene, and added materials such as barium sulfate, and endowed the catheter with various functions, thus completing the present invention

Abstract

The invention discloses a gastric diversion apparatus and an implantable catheter thereof. The implantable catheter comprises a membrane tube, wherein a stent is connected to one end of the membrane tube; and the membrane tube is prepared by mixing and blowing the following materials in parts by weight: 0.5-1.5 parts by weight of high density polyethylene, 4 parts by weight of low density polyethylene, 4 parts by weight of linear low density polyethylene and 0.5-1.5 parts by weight of barium sulfate. According to the scheme, the implantable catheter is made from a membrane tube material which is softer and more comfortable, lower in human rejection and free from injury; the implantable catheter is convenient in manufacturing process, low in cost and high in production speed; and the implantable catheter is applicable to long-term implantation in a human digestive tract.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric deflector and an implantable catheter 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...
