Finger artery flexible measurement program, finger artery flexible measurement equipment and finger artery flexible measuring method

摘要

Topic When flexibility of the finger artery which it is related to arteriosclerosis is appraised, without measuring the blood pressure, on the basis of the pulsating wave of the finger artery can measure flexible index of the finger artery simply and cheaply the finger artery flexible measurement program which, the finger artery flexible measurement equipment and finger artery flexible measuring method are offered.Solutions Pulsating wave data memory section 42 and cuffs pressure data memory section amplitude of the interchange component of 43 and the pulsating wave ( i) division flowing directly straight at the mean value component (i), when the NPV calculation section amplitude of 52 which calculates normalization pulsating wave capacity and the pulsating wave is maximum, the relative cuffs pressure calculation section 53 which calculates the difference of cuffs pressure and each cuffs pressure relative cuffs pressure (P _r) as and the below-mentioned formula (1) linear regression slope (n) the FEI calculation section 54 which it calculates as flexible index of the finger artery ln (NPV) =ln (bn) n P _r formula (1) as for b constant Functioning it can point to the computer as.
