PROBLEM TO BE SOLVED: To provide a drug solution administration device that enables a feed amount of a drug solution fed by a solution feed body part to be sequentially confirmed on a controller side, thereby improving a users convenience.SOLUTION: A drug solution administration device 300 includes: a solution feed body part 100 for feeding a drug solution into a living body and a controller 200 including a reception section 230 capable of receiving an instruction from a user and transmitting, based on the instruction, to the solution feed body part a solution feed instruction to the effect that the drug solution in a predetermined amount should be fed. The solution feed body part includes a second communication section 40 for receiving the solution feed instruction and transmitting a solution feed completion notification to the controller every time the solution feed body part completes a solution feed motion that feeds the drug solution in a unit solution feed amount set in advance to be smaller than the predetermined amount. The controller includes: a first communication section 250 for receiving the solution feed completion notification and a confirmation section 261 for confirming whether to complete the solution feed motion for feeding the drug solution in the unit solution feed amount based on a result received by the reception section on the controller side.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT
