Blood pump performance testing device

Abstract

The application provides a blood pump performance testing device, which comprises a first tank body provided with a first liquid storage cavity, a second tank body provided with a second liquid storage cavity, a loop pipe, a driving mechanism, and a testing mechanism. Two ends of the loop pipe are communicated with the first liquid storage cavity and the second liquid storage cavity respectively. The driving mechanism is in driving connection with an impeller of the blood pump and can drive the impeller to rotate, so that the liquid in the first liquid storage cavity can be drawn into the second liquid storage cavity through an outlet pipe of the blood pump and then enter the first liquid storage cavity through the loop pipe to form a circulation loop. The testing mechanism comprises a flow meter capable of detecting the liquid flow and a sensor capable of detecting the liquid pressure, and the flow meter and the sensor are arranged in the circulation loop. The blood pump performance testing device is used for simulating the working environment and the working state of an interventional blood pump, so as to realize the purpose of detecting the performance of the blood pump and judging whether the structural design of the blood pump is reasonable or not.
