A method of performing an intravenous drip injection includes a first step, a second step, a third step and a fourth step. A first step includes starting dosing an infusion solution containing a predetermined component by the intravenous drip injection to a dosing recipient. A second step includes extracting a body fluid from the dosing recipient being dosed with the infusion solution. A third step includes measuring a concentration of the predetermined component in the extracted body fluid. A fourth step includes varying the concentration of the predetermined component in the infusion solution, corresponding to the concentration of the predetermined component in the body fluid.

Method of and apparatus for performing intravenous drip injection

An ascorbic acid responsive electrode comprising an electrode, and a detection layer comprising a non-catalytic electron acceptor that receives an electron from ascorbic acid, an amino acid, and a saccharide and/or a soluble protein; wherein in the detection layer the electron acceptor is reduced by the ascorbic acid, and the reduced electron acceptor is oxidized at the electrode.

Electrode and biosensor for measuring ascorbic acid

The disclosure relates to a biosensor including electrodes, a hydrophilic region or layer, and a reagent layer that contains an enzyme and a mediator, and methods of producing thereof.

Biosensor and production method for same

Provided are a measuring apparatus and method for obtaining a measurement value from a response to a signal applied to a sample, wherein the measuring apparatus includes a first measuring unit that measures a first electric response to a first signal that is input to a first pair of electrodes that can come into contact with a sample, a second measuring unit that measures a second electric response to a second signal that is input to a second pair of electrodes that can come into contact with the sample, the second signal changing its value from a first level to a second level and thereafter maintaining the second level for a certain period of time, as a peak value of a response signal with respect to the change in the second signal, and a control unit that corrects a value indicating the amount of a measuring target component of the sample, the value being obtained from the first electric response, based on the peak value of the response signal.

Measuring apparatus and measuring method

A measurement apparatus to measure a physical quantity related to a measurement target by use of a sensor, comprising: an apparatus enclosure; a control unit to be electrically connected to the sensor; and a moving member including a sensor holding unit to hold the sensor, the moving member being movable to protrude the sensor holding unit outwardly of the apparatus enclosure and further including a conductive member to electrically connect the sensor to the control unit.

Measurement apparatus, and method for operating measurement apparatus

A sensor includes a substrate that includes an upper substrate and a lower substrate, and an electrode that is provided on the lower substrate, and the upper substrate, the lower substrate, and the electrode are formed by an optically transparent member.
