Description

Technical Field

[0001] The utility model relates to the technical field of balloon switches, in particular to a medical catheter balloon switch. Background Art

[0002] A catheter balloon switch is a device used to control the inflation and deflation of a catheter balloon. A catheter balloon is an inflatable round bag that is typically used to position and fix a catheter in the body. The catheter balloon switch controls the inflation and deflation of the balloon by controlling the flow of gas in and out. When inflation is required, the switch is turned on, and gas flows into the balloon to expand it; when deflation is required, the switch is closed, preventing gas from flowing into the balloon, and the balloon gradually deflates and shrinks. The use of a catheter balloon switch can precisely control the inflation and deflation speed and pressure of the balloon to meet specific medical needs.

[0003] When controlling the inflation and deflation of a catheter balloon, a balloon switch is usually set to turn it on or off. However, some catheter balloon switches are not simple to use, which can easily lead to operational errors during use, causing inflation and deflation to be turned on at the same time, thus affecting its working state. Moreover, when the catheter balloon switch is usually turned off, since inflation and deflation need to be turned off separately, it is not convenient to use. Therefore, there is an urgent need to solve this problem. Utility Model Content
