Measurement device
A measurement method includes a first measurement in which a characteristic amount of a specific analyte in a biological fluid with a biosensor having a reagent surface is measured. The method also includes a second measurement in which the tilt angle or rotation angle of the reagent surface from a neutral position, or vibration applied to the reagent surface, as motion information of living activity is measured. Additionally, the method may include recording the motion information, and controlling, based on the motion information, a measurement operation of the first measurement and a recording operation of the recording.
1. A measurement method of a measurer for measuring a characteristic amount of a specific analyte in a biological fluid with a biosensor having a reagent surface, the method comprising:
detecting whether or not the biosensor has been inserted into a sensor attachment part of the measurer;
confirming whether or not the biological fluid has been detected when the insertion of the biosensor is detected;
measuring a tilt angle or rotation angle of the reagent surface from horizontal as motion information of living activity when the insertion of the biosensor is detected and the detection of the biological fluid is confirmed;
detecting whether or not the motion information is within a predetermined range;
measuring the characteristic amount and recording the characteristic amount and the motion information when the motion information is within the predetermined range; and
recording a nullification of the measurement of the characteristic amount when the motion information is out of the predetermined range.
2. The measurement method according to claim 1 , wherein the predetermined range is ±30°.
3. The measurement method according to claim 1 , further comprising:
determining, based on the motion information, an amount of damage resulting from an impact to a housing to which the biosensor is attached; and
recording and/or notifying the amount of damage and a number of times the housing has been subjected to a damaging impact.
