Description

Technical Field

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

[0002] PTCA balloon catheter medical device is used in the field of interventional cardiology. Its main function is to perform interventional surgery in the coronary artery, including percutaneous coronary angioplasty (PTCA) and percutaneous coronary intervention (PCI). The purpose is to restore blood flow, improve myocardial ischemia symptoms, and prevent the occurrence and progression of cardiovascular diseases such as myocardial infarction by dilating the narrowed coronary artery and removing blood clots or substances attached to the blood vessel wall. During the operation, the PTCA balloon catheter enters the body cavity through the wrist artery or femoral artery cannula, guides to the narrowed blood vessel, and then expands the balloon to an appropriate size to restore the patency of the blood vessel.

[0003] If the pressure of the PTCA balloon catheter is too low, the blood vessels cannot be effectively sealed and the effect is difficult to achieve. If the pressure of the PTCA balloon catheter is too high, the catheter cuff will compress the blood vessel wall, causing a series of complications such as coronary artery rupture. Therefore, it is very important to maintain an appropriate PTCA balloon catheter pressure. The PTCA balloon catheter pressure often changes with changes in body position, surgical operation, depth of anesthesia and other factors. If not discovered in time, it may lead to vascular safety hazards. Therefore, it is crucial for clinicians or nurses to detect changes in PTCA balloon catheter pressure in a timely manner.
