WIPO Patent Application WO/2019/064888
Kind Code:
A1
Abstract:
This liquid medicine administration device is provided with a liquid medicine storage part, a driving part, a rotation detecting part, and a control part. The control part counts the number of rotations of the driving part from when a rotation sensor value reaches a blockage start threshold until the rotation sensor value reaches a blockage detection threshold. Moreover, the control part detects a blockage of a flow path when the rotation sensor value reaches the blockage detection threshold, and, on the basis of the counted number of rotations, rotates the driving part in a direction opposite to the direction for administering the liquid medicine.
