  • Patent number: 10582861
    Abstract: The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

  • Patent number: 8075493
    Abstract: A winding unit for an air tube provided to a blood pressure monitor includes a reel body rotatably supported by a case body, and a helical spring that biases the reel body in the direction in which the air tube is wound. The air tube includes a wound portion wound by the reel body, a fixed portion immovably fixed to the case body, and a freely movable portion that freely moves as the reel body rotates. The reel body has a housing containing the freely movable portion. A second free-movement end is disposed at an eccentric position relative to a rotational center of the reel body. The winding unit is thus configured to prevent bending of the air tube in the winding unit and to be downsized.
