products DETAIL
The Gingko PFT, a Heart Valve Pulsatile Flow tester, in accordance with the relevant requirements of the latest ISO 5840 series standards to simulate the pulsatile circulation mechanism of the heart. It is used for evaluating pulsatile flow characteristics of transcatheter and surgical heart valve implants (aortic, mitral, pulmonary and tricuspid valves). The system can simulate the pulsating blood flow field of the human body under various physiological and pathological conditions (left/right heart, different heart rates, different stroke volumes, different blood pressure, etc.), quickly and reliably collect and analyze physiological flow and pressure data, and integrate the functions of high-speed video shooting and playback. The entire process from control and acquisition to computation, analysis, and recording is managed by our proprietary, self-developed Gingko PFT TEST software.
