[0002] With the advancement of medical technology, medical balloons are widely used in angioplasty, heart valve repair, urethral dilation, and other fields. To ensure the safety and effectiveness of medical balloons, precise dimensional testing is required. Medical balloons are small expansion devices made of soft materials (such as polyurethane and silicone) and are primarily used to dilate narrowed blood vessels or other body passages. Their design typically includes one or more balloons that can be inflated and deflated, as well as a catheter for connecting to a delivery system. Depending on the application, medical balloons can have different shapes and sizes, ranging from a few millimeters to several centimeters. The size of a medical balloon is crucial to its function. For example, in angioplasty, a balloon that is too small may not fully dilate the blood vessel, while a balloon that is too large may cause blood vessel rupture. Therefore, accurately measuring parameters such as the length and diameter of the uninflated balloon and the maximum diameter after inflation is important for ensuring surgical effectiveness and patient safety.
