Patent ID: 8554316

Claim:
A biological information measurement apparatus comprising: a measurement device which acquires measurement value information of a living body; a calculator which calculates biological information based on the measurement value information obtained by the measurement device; and an input device which receives biological component information about a component of the living body measured in another device, together with date and time information at which the biological component information was received from the another device, wherein the calculator is configured to: determine whether or not the biological component information received from the another apparatus is effective based on the date and time information, calculate the biological information based on the biological component information and the measurement value information if the biological component information is determined as being effective, the biological information being calculated based on the biological component information and the measurement value information using the following equation: f (ρ)= a 2 ·1 /ρ+b 2 ·W+c 2 +S+d 2 ·e 2 calculate the biological information based on the measurement value information and not including the biological component information received from the another device if the biological component information is determined as being not effective, the biological information being calculated based on the measurement value information using the following equation: f (ρ)= a 1 ·1 /ρ+b 1 ·W+c 1 wherein, a 1 , a 2 , b 1 , b 2 , c 1 , c 2 , d 2 and e 2 are predetermined constants, ρ is a resistivity of the living body, S is a cross-sectional area of a body site, L is a site length of the body site, and W is a weight of the living body.
