  • Patent number: 11268926
    Abstract: It is intended to provide, for example, a liquid sample measurement device capable of measuring the amounts of components of a liquid with a high accuracy. A first voltage is applied to an electrode pair 21, 22, which composes a biosensor 1, to obtain a first response value, a second voltage is applied to an electrode pair 23, 24, which composes the biosensor 1, to obtain a second response value, and a current that is generated when a third voltage is applied to an electrode pair 23, 27, which composes the biosensor 1, is detected to obtain a third response value. A liquid sample measurement device 6 uses the first response value, the second response value, and the third response value to obtain the concentration of glucose and the amount of blood cells of blood as well as the value equivalent to the temperature of the biosensor 1.

  • Patent number: 10866205
    Abstract: Voltage is applied across a counter electrode and a working electrode, with which a blood sample is in contact, in such a state that an oxidant in a redox substance is not substantially in contact with a working electrode but is in contact with a counter electrode and a reductant is not substantially in contact with the counter electrode but is in contact with the working electrode, whereby the reductant and the oxidant are respectively oxidized and reduced to measure current produced upon the oxidation and reduction. According to the above constitution, while lowering the voltage applied across the working electrode and the counter electrode, the Hct value of the blood sample can be measured stably with a satisfactory detection sensitivity. This measurement can be carried out with a sensor chip comprising a working electrode (11), a counter electrode (12), and a blood sample holding part (14) having branch parts (18a, 18b).

  • Patent number: 10509005
    Abstract: Provided is a blood component measuring device or the like that can further suppress the measurement error of a blood component. The device detects an oxidation-reduction current generated by oxidation-reduction when a first voltage is applied to a first electrode pair 21, 22 of a biosensor 1, and converts the oxidation-reduction current (glucose response value) into a glucose conversion value. The device detects a current generated when a second voltage is applied to a second electrode pair 23, 24 of the biosensor 1, and converts the detected current (blood cell amount response value) into a blood cell amount conversion value. The glucose response value is measured more than once and the blood cell amount response value is also measured more than once within a predetermined period after the introduction of the blood into the biosensor 1.
