Biological information measurement device, and biological information measurement method using same

A biological information measurement device to which a biosensor is to be attached, the biosensor comprising a first electrode, a second electrode, a third electrode, and a reagent portion provided between the second electrode and the third electrode,

• the biological information measurement device comprising:
• a first input terminal to be connected to the first electrode;
• a second input terminal to be connected to the second electrode;
• a third input terminal to be connected to the third electrode;
• a voltage application portion that applies a voltage to the first input terminal, the second input terminal, and the third input terminal;
• and
• a control portion that is connected to the voltage application portion,
• wherein the control portion is configured to perform a first biological information measurement mode, then a voltage application stop mode, and then a second biological information measurement mode,
• in the first biological information measurement mode, first biological information is measured based on a current flowing through the first input terminal,
• in the voltage application stop mode, the application of the voltage to the first, second and third input terminals are stopped, and
• in the second biological information measurement mode, second biological information is measured by applying a voltage to the second input terminal and the third input terminal,
• the first biological information is a hematocrit value,
• when the hematocrit value represents a first hematocrit value, the control portion applies a first voltage to the second input terminal and the third input terminal in the second biological information measurement mode, or applies a voltage to the second input terminal and the third input terminal for a first application time in the second biological information measurement mode, and stops the application of the voltage in the voltage application stop mode for a first stop time,
• when the hematocrit value represents a second hematocrit value, the control portion applies a second voltage to the second input terminal and the third input terminal in the second biological information measurement mode, or applies a voltage to the second input terminal and the third input terminal for a second application time in the second biological information measurement mode, and stops the application of the voltage in the voltage application stop mode for a second stop time,
• the first hematocrit value is larger than the second hematocrit value,
• the first voltage is smaller than the second voltage, and
• the second application time is longer than the first application time.
