A wire holding test system and its test method

Abstract

The invention discloses a wire-holding test system and a test method thereof, which include a measuring device, a guiding catheter, a simulated clinical use device and a pressure charging device. The simulated clinical use device includes a water bath and a water bath placed in the water bath. The organ model, the guide catheter is connected with the organ model, the guide catheter can be penetrated by a guide wire and the interventional medical device can be inserted into the organ model along the guide wire, and the inflation device can Connected with the interventional medical device, the measuring device can be connected with the guide wire. The clinging test system provided by the present invention can test whether the clinging phenomenon occurs during the use of interventional medical devices, and can quantitatively evaluate the degree of clinging. Therefore, the clinging test system provided by the present invention and Its test method can detect and solve the problem of thread-holding in time during the design and production process of interventional medical devices, avoid the phenomenon of thread-holding during use, and enable the interventional medical device to be withdrawn from the body smoothly.

Description

technical field [0001] The invention relates to an interventional medical device testing system and a testing method thereof, in particular to a wire-holding testing system and a testing method thereof. Background technique [0002] Interventional therapy is an important method for the treatment of arterial vascular diseases developed in the past 30 years. Among them, the balloon dilatation technique is to insert the balloon catheter into the narrow part of the blood vessel with percutaneous puncture technology under the guidance of medical imaging equipment, and then expand the balloon under strict monitoring to expand the narrow part of the blood vessel, thereby recovering. lumen diameter. Taking coronary artery balloon dilatation as an example, coronary artery balloon dilatation is the basis of all interventional treatment techniques for coronary heart pain at present. The dilation catheter travels in the body from the arteriole into the aorta and finally to the blocked...
