  • Patent number: 11154657
    Abstract: 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.

  • Patent number: 11143595
    Abstract: A plasma spectroscopy analysis method includes a preliminary addition process in which a bonding agent that is an agent other than DMSA is added to the specimen collected from a living body to which meso-2,3-dimercaptosuccinic acid (DMSA) is administered, a concentration process in which the analyte heavy metal ions in the specimen at a vicinity of one of a pair of electrodes by applying a voltage to the pair of electrodes, and a detection process in which plasma is generated by applying a voltage to the pair of electrodes, and luminescence of the analyte metal ions caused by the plasma is detected.

  • Publication number: 20180024069
    Abstract: A plasma spectroscopic analysis method includes a concentration process including a voltage application period in which voltage is applied to a pair of electrodes in the presence of a sample thereby concentrating an analyte contained in the sample in the vicinity of at least one of the pair of electrodes; and a detection process of generating a plasma by applying voltage to the pair of electrodes and detecting light emitted by the analyte due to the plasma. An electric current between the pair of electrodes is constant while applying voltage for at least a part of the duration of the concentration process.
