Medical Valve Sensors: TAVR Fatigue Testing

How it Works
  1. LCM series or LSB series load cells are threaded in-line with a linear actuator and syringe piston measuring the force the linear actuator is applying to the syringe piston for test validation.

  2. As the linear actuator pushes down on the load cell/piston assembly the flow of fluid pushes open the TAVR valve.

  3. A check valve keeps the fluid moving only through the TAVR valve and a pressure vessel is used as a reservoir allowing the system to reach the burst testing pressures.

  4. The linear actuator then retracts, pulling the piston up, forcing the TAVR closed and refilling through the now open check valve.

  5. The USB220 displays and logs the data to a PC via SENSIT™ software. This data can be used to validate the accuracy and precision of the pressure generated by the syringe piston.
