Technical Field
The invention relates to the technical field of balloon catheter production detection, in particular to a balloon catheter pre-pressing pressure testing device.
Background
Angioplasty is a minimally invasive technique for effectively treating various vascular diseases, which inserts a balloon catheter into a diseased tube by puncturing the peripheral artery of a patient percutaneously, and dilates the stenotic diseased part to dredge the diseased vessel. The balloon catheter is composed of a balloon with expansion capacity at the distal end and a proximal pipe section. When the balloon part of the balloon catheter is pushed to a lesion part, the balloon is expanded by medium pressure, so that a lesion blood vessel is opened, the blood flow is recovered to be normal, the medium balloon is pumped back to release the pressure after the operation is finished, and then the catheter is taken out from the blood vessel of the patient. With the wide development of angioplasty, the pathological changes treated by doctors become more and more complex, and therefore, the performance requirements on balloon catheters become higher and higher.
In the current clinical application, the biggest problem of the balloon catheter is that the balloon catheter cannot pass through a lesion part. For example, if sharp protrusions are formed on a calcified lesion while a balloon catheter is passing through the calcified lesion, the balloon may be punctured by the sharp protrusions during the operation. For another example, in kyphoplasty with percutaneous balloon dilation, a lesion often has sharp objects such as broken bones, which may also puncture the balloon. Therefore, if the puncture resistance of the balloon is poor, the balloon catheter will not be usable.
Therefore, in order to evaluate the puncture resistance of the balloon, a certain amount of the balloon needs to be extracted for carrying out a compression resistance test in the production of the balloon catheter to ensure the quality of the balloon, and because the balloon is of a plastic structure, the molding can affect the test structure to a certain extent when the maximum deformation is tested, a certain pretightening force needs to be applied to the balloon, the influence caused by the plasticity of the balloon is eliminated, and the measurement result is very necessary.
