Biological sample measuring device
First Claim
1. A biological sample measuring device in which a biological sample measuring sensor is mounted, and the biological sample is measured, said biological sample measuring device comprising:
- a mounting portion to which the biological sample measuring sensor is mounted;
a voltage application section that applies voltage to a plurality of electrodes disposed along a capillary in the biological sample measuring sensor; and
a controller that determines whether the capillary is in a properly filled state or in a state in which pass-around or seepage has occurred and detects a degree to which the biological sample is introduced into the capillary by;
(a) applying a voltage to the electrodes and obtaining a current value,(b) obtaining a first output value from the current value, andwhen the first output value exceeds a first threshold, the controller concludes that the capillary has been filled with the biological sample, and calculates a threshold determination to determine if the threshold determination exceeds a second threshold, the second threshold indicating a sufficient quantity of the biological sample in the capillary; and
when it has been concluded that the capillary does not contain the sufficient quantity of the biological sample, the controller recommends an additional deposit of the biological sample and determines whether a second output value exceeds the first threshold, andagain calculates the threshold determination to determine if the threshold determination exceeds the second threshold, the second threshold indicating the sufficient quantity of the biological sample in the capillary.

Abstract
A biological sample measuring device in which a deposited biological sample is introduced into a capillary, a biological sample measuring sensor in which a reagent and the biological sample provided is mounted, and the biological sample is measured. The biological sample measuring device comprises a mounting portion, a voltage application section, and a detection component. The biological sample measuring sensor is mounted to the mounting portion. The voltage application section applies a measurement voltage to a plurality of electrodes disposed along the capillary. The detection component eliminates the effect of seepage of the biological sample by pass-around at the end of the capillary, or the effect whereby the plasma component seeps into the reagent, and detects the degree to which the biological sample is introduced into the capillary, based on the output result for the voltage applied by the voltage application section to the electrodes.
