Abstract: A drug cartridge includes: a cylinder 11 having a cylindrical cylinder columnar space extending in a longitudinal direction; a gasket 13 supported in the space so that the gasket is movable in the longitudinal direction; a drug 14 held in the space and at least including a liquid first component; and a first temperature sensor and an RF tag 16 arranged on a side surface of the cylinder. The RF tag 16 stores drug information that includes at least information indicating a type of the drug, and wirelessly transmits at least the information indicating the type of the drug and first temperature information indicating a temperature detected by the first temperature sensor in response to an instruction from outside.

Abstract: To extend the transmission distance with the voltage supply source and improve the communication performance of PLCs Solution. The power supply circuit includes a step-down DC/DC converter to which a voltage supplied from the power line is input and to which an input voltage is stepped down and output, a step-up/down DC/DC converter to which a voltage output from the step-down DC/DC converter or a voltage supplied from the power line is input and to which the input voltage is stepped up or stepped down and output to the power line communication circuit, a switch circuit for connecting an input of the step-up/down DC/DC converter to an output of the step-down DC/DC converter or power line, a voltage monitoring circuit for monitoring a voltage supplied from the power line, and a control circuit for controlling connection of the switch circuit based on the voltage value of the voltage supplied from the power line.

Abstract: A lancet is pressed against a puncture needle cartridge while fitting a puncture needle loading inlet of the lancet to the axis of a puncture needle on the puncture needle cartridge. In order to facilitate the operation, one of plural puncture needles, arranged in parallel, is tilted up from its initial position at a predetermined angle, and the puncture needle is guided into a puncture needle holding rod of the lancet. Simultaneously, the puncture needle is pressed up to a position where the rear end part of the needle pushes the bottom surface of a puncture needle loading chamber of the puncture needle holding rod, whereby the puncture needle is loaded. When discarding a used puncture needle, the puncture needle is inserted into a lancet guide member of the puncture needle cartridge, whereby the puncture needle is reliably captured to be discarded.
