Balloon, balloon connecting structure and balloon device

Abstract

The invention provides a balloon, a balloon connecting structure and a balloon device. The balloon connecting structure is used for being detachably connected to the balloon, the balloon connecting structure comprises an outer catheter and an inner catheter, one end of the outer catheter is used for being fixed to the exterior of a self-sealing structure, and when the outer catheter is subjected to first external force, the outer catheter is separated from the self-sealing structure; one end of the inner catheter is used for being fixed to the interior of the self-sealing structure, and when the outer catheter is subjected to second external force, the inner catheter is separated from the self-sealing structure; under the action of the first external force and the second external force, after the balloon reaches the stomach, the balloon connecting structure can be conveniently separated from the balloon; and when the outer catheter or the inner catheter is separated from the self-sealing structure, the inner catheter can be movably located in the outer catheter in a penetrating way. Preferably, after the balloon connecting structure is separated from the balloon, the balloon connecting structure and the balloon can be connected again as required, so that the volume of the balloon can be adjusted conveniently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon, a balloon connection structure and a balloon device. Background technique [0002] Obesity is excess or abnormal distribution of fat in the body. At present, the standard commonly used in the world to measure the degree of fatness and thinness of a human body and whether it is healthy is the BMI index, that is, the square of height to weight. When the BMI is between 25 and 29, it is evaluated as overweight, and when it exceeds 30, it is considered obese. As a metabolic disease, the hazards of obesity are not only reflected in the accumulation of fat, affecting appearance and daily life, but also cause a series of related physical and psychological complications, which threaten human health. The most important and common complications include type 2 diabetes and cardiovascular disease. Obesity and its complications have become one of the greatest threats to human health...

Problems solved by technology

[0005] In the current gastric balloon therapy, how to deliver the gastric balloon into the human body and separate the delivery device from the gastric balloon is still a problem to be solved. The complex structure of the delivery device in the prior art brings great difficulties to the processing and manufacturing. At the same time, it is very inconvenient in the operation of detaching from the gastric balloon; on the other hand, after the gastric balloon is implanted in the human body, it may be necessary to adjust the volume of the gastric balloon again. The technology to effectively carry out this operation; on the other hand, the balloon parts of the gastric balloon are mostly made of elastic materials such as silica gel. The choice of this material is conducive to the expansion of the volume of the balloon in the stomach, which has achieved the purpose of limiting the stomach volume

However, most of these materials are non-degradable, which makes them unable to release their volume spontaneously, and endoscopic operation is still required to remove them, which increases the risk of surgery

In addition, in terms of implantation methods, most gastric balloons also need endoscopic means such as gastroscopy, which also increases the risk of complications related to inner diameter such as esophageal perforation and intestinal infarction.
