  • Electronic blood pressure measurement device and blood pressure measuring method
    Patent number: 7118535
    Abstract: Prior to blood pressure calculations, air is enclosed in a blood pressure measurement bladder to be wound and mounted around the region for measurement, in advance. By referring to the variation in the pressure therein, the circumferential length of the region for measurement is detected based on the variation in the pressure therein during the winding correction determination process for the region for measurement. Then, the process enters blood pressure measurement, and the blood pressure measurement bladder is pressurized or depressurized. The pressure in the blood pressure measurement bladder is detected. A blood pressure based on the detected pressure is calculated according to the circumferential length of the region for measurement which has been detected in advance.

    Patent number: 7095304
    Abstract: According to a solenoid air valve, a flange portion of a moving core and a flange portion area of a bobbin implement a stop area defining a distance of travel of the moving core in a direction away from a fixed core. An end portion of a shaft portion of the moving core can project outward through an opening of a frame cover, so that a gap between a surface of the frame cover facing the shaft portion and a side surface of the shaft portion (distance: L2) can be minimized. Consequently, a solenoid air valve having a structure allowing improvement in magnetic efficiency by making smaller the gap between the frame and the moving core is provided.
