ディジタル表示血圧計。A cuff to be worn on a person to be measured, a pressure adjustment means for inserting or discharging outside air into the cuff, a semiconductor pressure car electrical conversion element provided at a position communicating with the cuff, and the semiconductor pressure car electricity. an amplifier that DC amplifies the output of the conversion element; a pulse component detector that detects a frequency component corresponding to the pulse contained in the output of the amplifier and outputs a detected pulse; an analog-to-digital converter for conversion; a latch circuit for latching the output of the analog-to-digital converter; and a latch circuit for detecting a measurement state from the output of the amplifier and performing latch control based on the detection pulse when in the measurement state. The latch control signal generation circuit includes a latch control signal generation circuit that connects a signal to the latch circuit, and a digital display device that is connected to the latch circuit, and when the latch control signal is generated, the latch control signal is generated in synchronization with the arterial wave. The digital display blood pressure monitor is configured to display the output of the analog-to-digital converter at the digital conversion rate when the converter is not in use.
