Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a method for detecting the pressure of a PTCA balloon catheter and a PTCA balloon catheter. Background Art

[0002] PTCA balloon catheters are medical devices used in the field of interventional cardiology. Their main function is to perform interventional surgeries within the coronary arteries, including percutaneous transluminal coronary angioplasty (PTCA) and percutaneous coronary intervention (PCI). The purpose is to restore smooth blood flow, improve myocardial ischemia symptoms, and prevent the occurrence and progression of cardiovascular diseases such as myocardial infarction by dilating stenosed coronary arteries and removing thrombi or substances adhering to the blood vessel wall. During the surgery, the PTCA balloon catheter is inserted into the body cavity through the radial artery or femoral artery, guided to the stenosed blood vessel site, and then the balloon is expanded to an appropriate size to restore blood vessel patency.

[0003] When the pressure of the PTCA balloon catheter is too small, it cannot effectively seal the blood vessel and is difficult to achieve its function. However, when the pressure of the PTCA balloon catheter is too high, the catheter sleeve compresses the blood vessel wall, causing a series of complications such as coronary artery rupture. Therefore, it is very important to maintain an appropriate pressure for the PTCA balloon catheter. The pressure of the PTCA balloon catheter often changes with factors such as body position, surgical operation, and anesthesia depth. If not detected in time, it may lead to potential safety hazards for blood vessels. Therefore, it is crucial for clinicians or nurses to promptly detect changes in the pressure of the PTCA balloon catheter. Summary of the Invention
