Abstract:
A liquid medicine administration device provided with a liquid medicine unit, said liquid medicine unit comprising a flow channel for pooling a liquid medicine and a plurality of flow channel electrodes that are formed respectively corresponding to a plurality of setting points in the flow channel. This liquid medicine administration device has a drive unit provided with a drive mechanism part that pushes out the liquid medicine in the flow channel by a liquid, said liquid being different from the liquid medicine, and allows the liquid medicine to flow. By using the liquid medicine administration device, it is possible to capture a change in the state at each setting point, i.e., the progress state of the liquid medicine, on the basis of the electrical physical quantities detected from the plurality of flow channel electrodes. As a result, the flow rate of the liquid medicine can be adjusted so that the the liquid medicine can be administered at an appropriate dose.
