| Research Abstract |
A pneumatic ventricular assist device(VAD) is widely used in Japan. However, the current system doesn't have enough capability of the driving status monitoring. In this study, we developed the compact monitoring system that can monitor the driving status and detect abnormal conditions such as low flow without remodeling the existing pneumatic VAD blood pump. The mean pump output was estimated from the air mass flow measured by using MEMS mass flow sensor at the driveline. As result, favorable estimated flow was acquired in the situation of mock circulation tests and animal tests(Relative error : 0.25%-14.1%). Additionally, the alarm system for detection of the low flow caused by interruption of the driveline and the inflow-outflow by using the airflow and the driving pressure was constructed.
