Problems solved by technology

However, the weight loss balloons currently used are all filled with normal saline and other liquids. During use, due to the large weight of the balloon filling, some patients will experience symptoms such as gastroptosis and stomach discomfort, which will affect the patient. health and reduce the quality of life; in addition, currently used weight loss balloons are all single-layer balloons, and there is a risk of intestinal obstruction after the balloon ruptures; at the same time, due to the large amount of filling fluid, the When taking it out, it will also cause the extraction process of the filling fluid to be more cumbersome

Embodiment Construction

[0021] In order to better understand the patent of the present invention, the following will be further described in conjunction with the accompanying drawings and embodiments.

[0022] A double-bag gastric volume reduction device includes a balloon part and a pipeline part.

[0023] Balloon parts such as figure 1 As shown, the balloon part includes a liquid bladder (1), an air bladder (2) and a three-lumen tube (3). The liquid bag (1) and the gas bag (2) are fixed on the three-lumen tube (3), and the liquid bag (1) wraps the gas bag (2). The liquid capsule (1) is made of silicon rubber material with a wall thickness of 0.2-1mm; the gas capsule (2) is made of silicon rubber or other high-elastic polymer materials with a wall thickness of 0.2-1mm. The volumes of the liquid capsule (1) and the gas capsule (2) can be changed by different injection volumes. The three-lumen tube is made of polymer material, and the three lumens of the three-lumen tube (3) are respectively a flui...

Abstract

A double-bag gastric volume reduction device, including a balloon part and a pipeline part, the balloon part includes a liquid bag, a gas bag and a three-lumen tube, the liquid bag and the gas bag are fixed on the three-lumen tube, and the liquid bag wraps the gas bag , There are two side holes on the wall of the three-lumen tube, so that the liquid-filled cavity communicates with the liquid bag, and the gas-filled cavity communicates with the gas bag; the side hole is covered with a thin-walled tube, which can realize the cavity and the liquid or gas in the balloon. one-way circulation. The pipeline part includes a mantle, a joint and a catheter, the end of the three-lumen tube is connected to the catheter through the joint, and the balloon part communicates with the joint and the catheter. The advantage of this device is that the weight of the entire balloon is reduced by using the difference in the filling in the double balloon without affecting the volume of the balloon, and the risk of gastroptosis and intestinal obstruction caused by leakage or rupture of the single balloon is reduced while ensuring the therapeutic effect. risk.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric volume reduction device assisted by a gastroscope. Background technique [0002] Implantation of gastric volume reduction balloons is a method of physical therapy for obesity. The principle of action is that the balloon with a certain volume occupies the space in the stomach, reduces the capacity of the stomach, and makes the patient feel full after eating a small amount. Control food intake to control and improve body weight. However, the weight loss balloons currently used are all filled with normal saline and other liquids. During use, due to the large weight of the balloon filling, some patients will experience symptoms such as gastroptosis and stomach discomfort, which will affect the patient. health and reduce the quality of life; in addition, currently used weight loss balloons are all single-layer balloons, and there is a risk of intestinal obstruction ...
