摘要:
This sensor has a diverter, such as a convex portion (608) and a concave portion (508), on the side wall (408) of a cavity (308). A biological sample deposited in a suction opening (52) is drawn into the cavity (308) by capillary action, but if the amount of biological sample is too small, either the biological sample is prevented from moving forward by the convex portion (608) and the concave portion (508), or the time it takes to reach a detecting electrode (33) is increased, which provides the user enough time to supply additional biological sample before a false detection occurs.

The concentration measurement method includes: introducing a predetermined amount of the biological sample into the capillary; measuring a temperature of the biological sample by applying a first voltage to the electrode unit when the temperature of the biological sample is measured, the first voltage allowing the temperature measurement to be less affected by increase and reduction in an amount of the analyte contained in the biological sample; measuring the concentration of the analyte contained in the biological sample by applying a second voltage to the electrode unit; measuring an environmental temperature in a surrounding of the biological sample; and correcting the concentration of the measured analyte based on the measured temperature of the biological sample and the measured environmental temperature.

A measurement device includes a housing that has an attached biosensor that includes a reagent selectively responding to a specific analyte in a biological fluid, and is configured so as to be carried by a user, an analyte measurer that measures a concentration of the specific analyte with a biosensor, and a motion measurer that measures a motion level of the housing. A living activity level calculator calculates a living activity level of the user based on the motion level measured by the motion measurer, a recorder records the living activity level calculated by the living activity level calculator, and a controller associates the concentration of the specific analyte measured by the analyte measurer with an event of living activity of the user, estimated based on the living activity level recorded in the recorder, and records them in the recorder.

It is an object to provide an information recording medium with which information symbols can be suitably read. This information recording medium comprises a sheet-form member (33), a plurality of information symbols (18) that are displayed on the surface of the sheet-form member (33) and each have the same information, and an edge line (34) that is provided at one end and/or the other end of the sheet-form member (33) and allows an information reading device which reads the information symbols (18) to recognize the end of the sheet-form member (33).
摘要:
A biosensor system can comprise a sensor chip and a measurement device. The sensor chip comprises a capillary and electrodes disposed within the capillary. The height of the capillary is set to be less than the maximum value of the sum of the diffusion distance of an electron-transfer mediator and the diffusion distance of an analyte at the upper limit of the measurement guaranteed temperature of the biosensor system. The measurement device applies an open circuit voltage, a voltage that is lower than during concentration measurement, or the like to the electrodes of the sensor chip.

With this biological sample measuring device, the determination section performs measurement at specific intervals in a first measurement period from the start of measurement until a first time, and performs measurement at specific intervals in a second measurement period that comes after the first measurement period, calculates the difference between the measurement values in corresponding specific periods, and finds a plurality of first difference determination values, on the basis of a plurality of current values measured in the first measurement period and a plurality of current values measured in the second measurement period, finds a second difference determination value by finding the difference at specific intervals in the plurality of first difference determination values, and determines whether or not a reagent movement error and/or exposure error of the biological sample measurement sensor has occurred, on the basis of the first and second difference determination values.

The present invention provides a method of measuring a component in blood, by which the amounts of blood cells and an interfering substance can be measured with high accuracy and high reliability and the amount of the component can be corrected accurately based on the amounts of the blood cells and the interfering substance. In a sensor for measuring a blood component, a first working electrode 13 measures a current that flows during a redox reaction of a blood component, a second working electrode 17 measures the amount of blood cells, and a third working electrode 12 measures the amount of an interfering substance. Next, based on the measurement results, the amount of the blood component to be measured is corrected. Thus, more accurate and precise measurement of the amount of the blood component can be realized.
