Abstract: The purpose of the present invention is to reduce the influence of pump ripple and to achieve fast control of cuff pressure with a general purpose magnetic valve when continuously measuring blood pressure. A blood pressure meter 1 includes a pump 11, a cuff 12 to be mounted on the site of blood pressure measurement of a subject, a first valve 13, a first pressure sensor 14, a detection sensor 18, a second valve 23, and a second pressure sensor 24. The blood pressure meter 1 also includes a valve opening adjustment unit 42 and a blood pressure measurement unit 43. The first valve 13 adjusts discharge volume of the pump 11 and the second valve 23 adjusts cuff pressure inside the cuff 12. The first pressure sensor 14 detects the discharge pressure of the pump 11, the second pressure sensor 24 detects the cuff pressure, and the detection sensor 18 detects the amount of light associated with the volume of the artery at the site of blood pressure measurement of the subject.

Abstract: A cuff includes a band that is wound around a measuring position where blood pressure is measured and an air bag that is provided on a measuring position side of the band and whose length in a length direction is shorter than an outer circumference of the measuring position. A first spacer and a second spacer are respectively provided at the ends in the length direction of the air bag. The band is wound around the measuring position so as to cover the first spacer and the second spacer and detachably fixed by a fixing portion to a surface on an opposite side to the measuring position side.

Abstract: A sphygmomanometer cuff for finger, includes, a base unit including a first curved portion extending along a part of periphery of a finger defined as a measurement examinee's target region, at least one movable unit connected via a rotatable unit to the base unit, including a second curved portion extending along another part of periphery of the finger, and being attachable to the finger in a state of an opening being formed along the periphery of the finger, an adjustment unit configured to adjust an angle of the movable unit to the base unit, and a compression unit provided along at least a part of an inner peripheral portion formed along the periphery of the finger by the base unit, the movable unit and the opening, and compressing the part of periphery of the finger.

Abstract: A cuff-block for a finger arterial blood pressure monitor is able to relieve a blood flow impediment and the hindrance of a finger motion at the measuring site during the finger arterial blood pressure monitoring. A disk-like cuff (12) for local pressurization is attached over a finger artery (6) on a proximal finger portion (4) of a measured finger (1), this cuff (12) is held by a cuff-holding portion (11a) of an annular cuff-fixing member (11) put from the tip end portion of the measured finger (1), and the cuff-fixing member (11) is supported on the measured finger (1) with local supportings by forked supporting points (11a, 11b) of the cuff-fixing member (11) placed on respectively portions of a proximal joint (1c) and a medial one (1b).

Abstract: A constant current having high frequency and a known small current value is flown by a current supplying electrode portion (20) through a chest of a living body, variations of impedance at respective positions of the chest are detected by a voltage detector portion (30) and output as detected signals in relation to the respective positions of the chest and a mapping and display portion 40 performs a signal processing on the basis of the detected signals and produces a map corresponding thereto and displays it in a two dimensional plane. Therefore, it is possible to monitor hemodynamics in a wide area of the living body in two dimensional coordinates.

Abstract: A test system for optical disks, comprising a spindle motor for clamping and rotating an optical disk at a constant speed; an encoder for generating a pulse output corresponding to the angle of rotation of the motor; a measuring head comprising focus and tracking servo mechanisms for causing the focal point of a laser beam irradiating the disk to follow the guide groove thereof, and a displacement detector for optically detecting the displacement of a focusing lens driven by the servo mechanisms; the measuring head being operative to generate an output signal proportional to the displacement of the focusing lens; a feed mechanism for moving the measuring head in the radial direction of the disk; a control circuit for controlling the operations of the motor, the servo mechanisms and the feed mechanism; an analog to digital converter for converting the output of the measuring head at a timing according to the pulse output of the encoder; and a computer for commanding the control circuit and for computing the ou
