Title: LIQUID MEDICINE ADMINISTRATION DEVICE
Abstract:
A liquid medicine administration device comprises an administration unit, a drive unit, a detection unit, an impedance measurement unit, an arithmetic logic unit, and a storage unit. After the drive unit feeds a prescribed dose of liquid medicine to an administration unit, the arithmetic logic unit determines the existence of a liquid medicine leak on the basis of post-administration impedance information measured by the impedance measurement unit and a threshold value stored in the storage unit.
