CIRCULATORY ORGAN FUNCTION-COMPUTING DEVICE

PROBLEM TO BE SOLVED: To provide a circulatory organ function-computing device improved in accuracy of computation of an index value of circulatory organ function.SOLUTION: A circulatory organ function-computing device 1 includes: a pressing unit 10; a pressure detection unit 30; a pressure control unit 20; a pulse wave detection unit 40; and a feature quantity computing unit 50. The pressing unit 10 presses an upper arm of a body of a measured person. The pressure detection unit 30 detects a pressing force generated by the pressing unit 10. The pulse wave detection unit 40 detects pulse wave information based on output signal from the pressure detection unit in a process to change the pressing force by the pressure control unit 20. The feature quantity computing unit 50 computes processed information by combining pieces of the pulse wave information, computes variable values from the processed information, and computes a feature quantity to be an index value of circulatory organ function by substituting the variable values into a computing equation including multiple variables and coefficients got in advance by multivariable analysis.
