Description

Technical Field

[0001] The utility model relates to the technical field of volume reduction balls, in particular to a disposable intragastric volume reduction ball. Background Art

[0002] Gastric volume reduction balloons, also known as intragastric balloons, are a method of achieving weight loss through gastric volume reduction surgery. Their mechanism of action primarily involves stimulating mechanoreceptors in the stomach, which in turn stimulate the vagus nerve, sending signals to the hypothalamus, inducing a feeling of fullness and slowing gastric emptying. Intragastric balloons can be divided into liquid-filled intragastric balloons, gas-filled intragastric balloons, or a combination of the two. The specific procedure is: under endoscopic surgery, the balloon is placed into the stomach and injected with saline to expand it, occupying part of the gastric volume, thereby reducing food intake and achieving the goal of weight loss.

[0003] The intragastric balloon is pre-compressed in a capsule and connected to a thin, flexible, water-filled catheter. The capsule is swallowed and delivered into the stomach, while the other end of the catheter remains external to the body. Once inside the stomach, the capsule dissolves, releasing the balloon from the capsule. Subsequently, a certain amount of saline is injected into the balloon through the external end of the catheter to inflate it. Once inflated, the catheter separates from the balloon, and the self-sealing valve on the balloon automatically closes. During subsequent use, staff will need to adjust the balloon's size according to the weight loss process. However, once the catheter is completely separated from the balloon, the inflated balloon's smooth surface makes it difficult to reconnect the balloon to the catheter. If staff fail to maintain proper pressure, the balloon can easily be ruptured, requiring a new one, resulting in unnecessary waste.

[0004] To this end, we designed a disposable intragastric volume reduction ball. Utility Model Content
