|Title||FINGER ARTERY ELASTICITY MEASURING PROGRAM, FINGER ARTERY ELASTICITY MEASURING DEVICE, AND FINGER ARTERY ELASTICITY MEASURING METHOD|
[PROBLEMS TO BE SOLVED] A finger artery elasticity measuring program, a finger artery elasticity measuring device and a finger artery elasticity measuring method are provided for making it possible to measure an elasticity index of a finger artery in accordance with a pulse wave of a finger artery without measuring a blood pressure in evaluating the elasticity of the finger artery related to the degree of arterial sclerosis. [MEANS FOR SOLVING THE PROBLEMS] A finger artery elasticity measuring device is comprised of a pulse wave memory unit (42), a cuff pressure data memory unit (43), an NPV calculating unit (52) for dividing an amplitude (?I) of an alternate component of a pulse wave by an average value of direct components (I) to calculate a normalized pulse wave volume, a relative cuff pressure calculating unit (53) for calculating a difference between a cuff pressure at the maximum amplitude of the pulse wave and each cuff value as a relative cuff pressure (Pr), an FEI calculating unit (54) for calculating a linear recursive slope (n) of the following equation (1) as an elasticity index of the finger artery: In(NPV) = In(bn)-n Pr ... (1) where b is a constant, so as to make a computer function.
