Title:
生体状態量測定装置
Document Type and Number:
Japanese Patent JP5701528
Kind Code:
B2
Abstract:
An apparatus including a detecting unit that detects information indicating a state of an organism from the organism or an organism specimen extracted from the organism and outputs the detected information as a current, a current-voltage conversion circuit that converts the current output from the detecting unit into a voltage, a double-integration-type A/D conversion circuit having an integration capacitor that is charged based on a voltage output from the current-voltage conversion circuit and is thereafter discharged, and a counter that measures a charge time during which the integration capacitor is charged and a discharge time during which the integration capacitor is discharged, the A/D conversion circuit converting into digital quantities the charge time and the discharge time measured by the counter, and outputting the digital quantities, and an information processing unit that calculates a state quantity of the organism based on the digital quantities output from the A/D conversion circuit.
