Test fluid measurement device and sensitivity calibration method thereof
First Claim
1. A test fluid measurement device comprising:
- a biosensor that measures the amount of a certain substance that is contained in a test fluid;
output acquisition means for acquiring the output value of said biosensor when a reference fluid containing said certain substance that is set to a specified density is applied to said biosensor during a sensitivity calibration of said biosensor;
setting means for calibrating the sensitivity of said biosensor by setting a reference value that will be a reference for measurement by said biosensor using said output value that was acquired from said biosensor by said output acquisition means;
judgment means for determining whether or not a said output value that is newly acquired from said biosensor by said output acquisition means during said sensitivity calibration by said setting means is suitable to be used as the setting for said reference value based on a previous output value that has already been acquired from said biosensor by said output acquisition means; and
detection means for detecting when said reference fluid, which is the subject of acquiring another output value by said output acquisition means, is additionally applied to said biosensor after said judgment means determines that an output value is not suitable as the setting for said reference value,wherein when said judgment means has determined that the new output value is not suitable as the setting for said reference value, the additional application of more reference fluid to said biosensor is detected without performing a cleaning process.

Abstract
A test fluid measurement device includes an output acquisition unit for acquiring an output value from a urinary sugar sensor, when a reference fluid, set to a specified density, is applied to the urinary sugar sensor. By using this output value to set a reference value, a reference value setting unit calibrates the sensitivity of the urinary sugar sensor. During sensitivity calibration, an output value judgment unit determines according to an output value that is already acquired by the output acquisition unit whether or not the output value that is newly acquired by the output acquisition unit is suitable to be set as the reference value. After an output value is determined not to be suitable as the reference value setting, a reference fluid detection unit detects when more reference fluid from which another output value is to be acquired by the output acquisition unit has been additionally applied.

19. A sensitivity calibration method for calibrating the sensitivity of a biosensor, comprising steps of:
-
providing a biosensor that measures the amount of a certain substance that is contained in a test fluid; acquiring the output value of said biosensor when a reference fluid containing said certain substance that is set to a specified density is applied to said biosensor during a sensitivity calibration of said biosensor; setting a reference value that will be a reference for measurement by said biosensor using said acquired output value; determining whether or not a said output value that is newly acquired from said biosensor during said sensitivity calibration is suitable to be used as the setting for said reference value based on a previous output value that has already been acquired; and detecting when said reference fluid, which is the subject of acquiring another output value, has been additionally applied to said biosensor after an output value is determined not to be suitable as the setting for said reference value, wherein when said determining step has determined that the output value is not suitable as the setting for said reference value, the additional application of more reference fluid to said biosensor is detected without performing a cleaning process. - View Dependent Claims (20)
