DRUG ADMINISTRATION MECHANISM AND METHOD FOR PRODUCING PUMP UNIT FOR DRUG ADMINISTRATION MECHANISM

摘要

This drug administration mechanism is for administering a liquid drug packed in a drug container (F1) to a patient. The drug administration mechanism is provided with the drug container (F1), a main body (2), and a pump unit (3) attached to the main body (2). The pump unit (3) is provided with a pump that is driven by a piezoelectric element and a characteristic data holding unit (38) for readably holding characteristic data relating to the input/output of the pump. The main body (2) is provided with: a reading unit (27) that reads the characteristic data held by the characteristic data holding unit (38); a correction unit (2611) that determines a control correction value on the basis of the characteristic data read by the reading unit (27); and a pump control unit (2612) that controls the pump on the basis of the determined control correction value.
