DEVICE, METHOD, AND SYSTEM FOR CALIBRATION OF A FLOW METER USED IN CONJUNCTION WITH A VENTRICULAR ASSIST DEVICE

摘要

A blood flow calibration system 500 comprising a computer 400 operable to determine and store calibration data for a flow meter 124, a test system 530 operable to simulate blood flow for the flow meter 124, thereby allowing the computer 400 to determine the calibration data, and a programmer 300 operable to transfer the calibration data from the computer 400 to the flow meter 124. The flow meter 124 preferably includes a power management circuit 348a, b operable to detect whether the flow meter 124 is powered. In the event that the flow meter 124 is unpowered, the power management circuit 348a, b is preferably able to supply power to a portion of the flow meter 124 in order to transfer the calibration data thereto.
