  • DRUG CARTRIDGE, CASSETTE, DRUG INJECTION DEVICE, AND DRUG INJECTION SYSTEM
    Publication number: 20230321353
    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.
