摘要:
An electronic blood pressure meter includes a cuff that is to be worn on a measurement area, a piezoelectric pump that adjusts a pressure applied to the cuff, a drive circuit that drives the piezoelectric pump, and a controller that outputs, to the drive circuit, a pulse signal defining a driving timing of the piezoelectric pump. The drive circuit includes a switching circuit for switching a connection relationship between respective voltages applied to both ends of the piezoelectric pump in response to corresponding first and second driving signals, and a signal generation circuit that outputs the first and second driving signals based on the pulse signal outputted from the controller. The signal generation circuit has a signal conditioning circuit hat adjusts timings of the first and second driving signals so that the phases of the first and second driving signals do not overlap.
