ABSTRACT:
An electronic sphygmomanometer includes CPU-controlled peripheral elements such as a pump, an amplifier, an A/D converter and a printer. During measurement of blood pressure, power consumption is reduced by supplying power to these peripheral elements only when they are driven or operated. When a blood pressure measurement or a print-out of measured values ends, the CPU acts to cut off its own power to reduce power consumption further. The sphygmomanometer further includes a timer constantly supplied with power for the purpose of preserving time information. Operating power is supplied to the CPU in synchronism with a pulse signal outputted by the timer every minute. When the pulse signal arrives, the CPU reads in time information from the timer, causes the time information to be displayed by a display device, then cuts off its own power and waits for the next pulse signal. By repeating such processing, time is displayed while power consumption is minimized.
