Instantaneous position of the flexing member in pneumatic blood pumps is monitored on-line by measuring the electrical capacitance across the gas space within the pump. Monitor output is utilized in closed-loop pump control and for automatic pump shutdown in response to operational abnormalities. Thus, safety and efficacy are enhanced through operational optimization, automatic safety features, and facilitated evaluation.
通过测量气动血泵内气体空间的电容来在线监测挠曲部件的瞬时位置。监测输出用于闭环泵控制以及在出现操作异常时自动关闭泵。因此,通过操作优化、自动安全功能和便于评估,提高了安全性和有效性。
