Title:
薬液投与装置及び薬液投与装置の制御方法
Document Type and Number:
Japanese Patent JP7105791
Kind Code:
B2
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 detects blockage of a flow path 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.
