<p>PROBLEM TO BE SOLVED: To provide a medicine solution administration device controlling an amount of solution at high accuracy with a compact configuration.SOLUTION: A main body 2 of a medicine solution administration device 1 is structured as follows: a magnet 68 is placed on a diaphragm 64 of an injection pump 44; a detection part 69 composed of a Hall element 67 is mounted in the vicinity of the magnet; and a detection signal SD corresponding to a displacement width of the diaphragm 64 is generated in non-contact state by the Hall element 67. The main body 2 controls a voltage control signal CV to control the detection signal SD to feed back so as to come close to a target voltage, so that the displacement width of the diaphragm 64 is made close to a target distance to meet a unit discharge amount to a target discharge amount. Accordingly, the main body 2 controls a supply time of the voltage control signal CV to discharge the target discharge amount of the medicine solution as many times as desire and thereby the administration amount of the medicine solution can be adjusted at high accuracy.</p> |
