摘要:
The blood pressure monitor (10) comprises an artery pressing section which locally presses an artery of the extremities or fingers at an arbitrarily variable pressing force, a vibration sensor (22) detecting a vibration of the artery at the pressed point or points on a peripheral side thereof, a mounting mechanism (26) which positions the artery pressing section and the vibration sensor (22) on the artery, a blood pressure determination section which determines the maximum and minimum pressures based on various pressing force values applied by the above-mentioned artery pressing section and signals detected by the vibration sensor (22) at these various pressing force values, guides (34) which are provided on each side of the vibration sensor (22) and guide the vibration sensor (22) to the artery by being located on the both sides of the artery, and a peripheral side pressing section which presses the artery on the peripheral side from the vibration sensor (22). The blood pressure monitor (10) does not impart an unpleasant or disagreeable feeling to the subject.

An FFT treating section (40) carries out the frequency analysis of a pulse waveform MHj excluding a body movement component to yield pulse wave analysis data MKD and then a tidal wave-character extracting section (50) and a dicrotic wave-character extracting section (60) yield a tidal wave-character data (TWD) and a dicrotic wave-character data (DWD) showing the characteristics of a tidal wave and dicrotic wave respectively. Then, a pulse condition judging section (70) yields pulse condition data (ZD) on the basis of this data (TWD, DWD) and in succession a notifying section (80) advises of the pulse condition of a subject.

The test subject attaches pulse wave detectors 1 to his fingertips, and presses down on pressure sensor 110. As a result, CPU 4 determines the DC component of the received light signal LS, and stores this in calibration table 50 in association with the pressure level. Subsequently, CPU 4 calculates threshold values, which can be used for grading the touch sensation, based on maximum value Pmax of the pressure level and calibration table 50, and stores this result in threshold table 51. When the subject grips an object with his fingers, the blood flow volume is detected by pulse wave detector 1 as received light signal LS. CPU 4 calculates the DC component of received light signal LS, compares this result to the threshold values stored in threshold value table 51, generates touch information SJ, and displays this on LCD 108. Accordingly, in this case, pulse diagnosis can be easily performed by expressing the degree of pressure in the pulse diagnosis as touch information SJ.
摘要:
An exercise intensity and exercise quantity measuring device is disclosed, which is capable of measuring the exercise intensity, irrespective of the type, of exercise, and measuring the exercise quantity only when the user is carrying out exercise of suitable intensity. The user first estimates his Vo.sub.2max in advance by the conventional direct method, and inputs this value into the device. The device determines upper and lower limit values of pulse rate corresponding to this Vo.sub.2max. During the time of exercise when pulse rate is between the upper and lower limit values, CPU 308 increments the accumulated time stored in RAM 309, at intervals based on a clock pulse supplied by oscillation circuit 311 and frequency dividing circuit 312. At the same time, CPU 308 compares the pulse waveform during exercise and the pulse waveform at rest, and estimates the exercise intensity.
摘要:
An apparatus for detecting pulse waves and motion intensity of a living body in motion is disclosed. The apparatus has photosensors of the photo-coupler type for wavelengths of 660 nm and 940 nm, respectively. The sensors are attached to a person under examination, and provide output signals which include a blood pulse signal as well as body motion components superimposed on the blood pulse signal. These signals are subjected to the Fourier transformation in a fast Fourier transformation circuit, and then applied to a comparator which in turn compares amplitudes of major frequency components (components associated with pulse waves and body motion) to one another. According to the comparison result, a decision circuitdiscriminates the pulse wave from the body motion. A display unit displays the pulse rate corresponding to the fundamental frequency of the detected pulse wave. The display unit also displays the change in motion intensity detected by the decision circuit. Thus, the present invention allows the detection of the change in motion intensity during the exercise of a person under the examination.
摘要:
An electronic watch with a multiple function display which is able to display biorhythms or the like in a format appealing to the sense of sight is presented. This electronic watch moves a plurality of hands by means of a plurality of step motors, and displays the biorhythms with the respective hands. Since the respective hands go through a single rotation when the corresponding step motor performs a set number of steps, in order to ensure that these single rotations are accurately timed with the periods of the biorhythms, movement control of the step motors is conducted.
