定装置。[Claims for Utility Model Registration] A compression device to which pressure from a pressure supply source is supplied, and a compression device that compresses a living body to detect pulse sounds generated from arteries in the living body. A pulse sound sensor that outputs a pulse sound signal representing a pulse sound, a pressure sensor that detects the pressure within the compression device and outputs a pressure signal representing the pressure, and a pressure sensor that outputs a pressure signal representing the pressure. a bandpass filter that passes a vibration component synchronized with the pulse contained in the pressure signal; and a gate that is opened by a trigger signal based on the vibration component of the pressure signal that has passed through the bandpass filter to collect the pulse sound signal from the pulse sound sensor. In the blood pressure measuring device of the type that measures the blood pressure value based on the generation and disappearance of the pulse sound, the pass frequency band of the band filter is 10 to 2.
A blood pressure measuring device characterized in that the blood pressure is set within the range of 0Hz.
