Abstract

A balloon fatigue testing device consists of a machine base (1), a balloon infusion pump (2.1), a balloon expansion pump (2.2), a hose (3), a three-way (4), a three-way valve (5.1) and ( 5.2), special connectors (6.1) and (6.2), electric pusher (8), Luer connector (9), pin shaft (10), front support (11), rear support (12), double-ended screw Column (13), limit column (14), upper connection block (15), pressure plate (16), pump backing plate (17), valve seat (18), lower connection block (19), intelligent pressure controller (20 ) and standard parts (21-26); the electric push device (8) pushes the piston rod of the balloon dilation pump (2.2) to reciprocate, so as to realize the fatigue test of a balloon catheter delivery system (7).

Description

Technical field: [0001] The invention relates to a test device for a vascular stent balloon catheter delivery system, in particular to a balloon fatigue test device. Background technique: [0002] The existing stent balloon catheter delivery system, as a tool for stent delivery, plays an extremely important role in the stent delivery process; under the guidance of the guide catheter and guide wire, the stent is delivered to the lesion, The whole process until the balloon expands the stent and withdraws it. During the operation, the performance of the balloon catheter delivery system directly affects the success or failure of the operation. Since there are different thickness and very curved blood vessels in the human body, and severe diseased blood vessels are accompanied by calcification, it is necessary for the balloon catheter delivery system to have a very small outer diameter, good flexibility, and strong pushability to facilitate passage through tortuous The diseased...
