    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: 10456200
    Abstract: The position of a metal marker 5 relative to an optical fiber 6 is fixed, and the metal marker 5 can be moved up close to a target site such as a thrombus. It is preferable that the position, in an optical fiber longitudinal direction, of a front-end face of the optical fiber 6 is coincident with the position, in an optical fiber longitudinal direction, of a front-end face of the metal marker 5. More specifically, since the distance between the target site and the front end of the optical fiber 6 is known by radiography, it becomes unnecessary to use a large quantity of contrast agent and irradiate a laser beam depending on skill and intuition, and therefore an effective laser beam irradiation becomes possible.
