摘要： PROBLEM TO BE SOLVED: To enable handy and inexpensive evaluation of an autonomic nerve function of an organism. SOLUTION: This apparatus evaluates the function of an autonomic nerve of an organism based on a first fluctuation component HFC comprising a frequency component almost equal to a respiration frequency of an organism which is extracted from a fluctuation of a pulse cycle TRR of the organism as detected continuously and a second fluctuation component LFC comprising a specified frequency component lower than the respiration frequency of the organism extracted from changes in the blood pressure value of the organism as detected continuously. A time difference TDRP is continuously calculated by a time difference calculation means 64 up to the maximum inclination point of a photoelectric pulse of the organism which is detected by a photoelectric pulse detection probe 12 sequentially from an R wave of an electrocardio induction wave of the organism detected sequentially by an electrocardio induction device 48. Changes in the inverse of the time difference TDPP are estimated by a blood pressure change estimation means 66 as changes in the blood pressure value.

摘要： PROBLEM TO BE SOLVED: To reduce the frequency of blood pressure measurement using a cuff and load on a human body, by actuating blood pressure measurement motion using a cuff when the change trend of the reciprocal of the phase difference between a pressure pulse wave and an electrocardiac induction wave and the change of monitored blood pressure are different. SOLUTION: When an electrocardiac induction wave is detected by an electrocardiac induction device 60 and a pressure pulse wave generated in an artery of a human body is detected by a pressure wave sensor 46, the phase difference between both waves is calculated by a phase difference calculation means 76 and the change value of the reciprocal of the phase difference is calculated by a phase difference reciprocal change value calculation means 78. On the other hand, when a monitored blood pressure value is determined by a monitored blood pressure value determination means 74 based on a pressure pulse wave, a change value of the maximum blood pressure value at the monitored blood pressure value is calculated by a monitored blood pressure change value calculation means 80. When a comparison value between the change value of the reciprocal of the phase difference and the change value of the maximum blood pressure value exceeds a prescribed standard value, blood pressure motion using a cuff according to a blood pressure measurement means 70 is actuated by an actuating means 82.

摘要： PURPOSE: To provide a measuring device for pulse wave propagation velocity by which pulse wave propagation velocity can be obtained with good accuracy. CONSTITUTION: Transmission velocity VM of a pulse wave in artery is calculated based on a time differential TDRP in a propagation velocity calculating means 82, when the time differential TDRP from a specified site at which an electrocardiograpahic induction waveform detected by an electrocardiographic induction device 60 is generated periodically to the specified site at which the pulse wave detected by a pressure pulse wave sensor 46 is generated periodically is calculated by a time differential calculating means 80. This propagation velocity VM is calculated based on the distance including propagation in the aorta connected to a heat, therefore the pulse wave propagation velocity is obtained with high accuracy in comparison with that in the conventional case which is calculated base on a little time differential, because the propagation distance is long and the propagation time, in order words the time differential TDRP is prolonged due to low pulse wave propagation velocity in artery as a diameter of the aorta is large.
