  • Drug solution administration device and method for controlling drug solution administration device
    Patent number: 11484656
    Abstract: A drug solution administration device includes a drug solution reservoir, a drive unit, a rotation detection unit, and a control unit. The control unit counts the number of rotations of the drive unit from when a rotation sensor value reaches a blockage start threshold value until the rotation sensor value reaches a blockage detection threshold value. Further, the control unit determines that a blockage of a flow path has occurred when the rotation sensor value reaches the blockage detection threshold value, and rotates the drive unit in a direction opposite to a direction in which the drug solution is administered based on the counted number of rotations.
