Title: LIQUID MEDICINE ADMINISTRATION DEVICE AND OPERATION METHOD THEREOF
Abstract:
This liquid medicine administration device (10) is provided with: a cylindrical body (12) filled with a liquid medicine (M); a gasket (34) disposed in the cylindrical body (12); an advancing mechanism (36) for advancing the gasket (34) toward a tip; a driving mechanism (42) having a motor (40) that drives the advancing mechanism (36); a battery (26) that supplies power to the motor (40); and a control unit (28) that controls the rotation speed of the motor (40). The control unit (28) operates the motor (40) at a first rotation speed (S1) during a first displacement section (an initial sliding section), and operates the motor (40) at a second rotation speed (S2), which is faster than the first rotation speed (S1), during a second displacement section (a general sliding section) following the first displacement section.
