A medicine transfusion apparatus transfusing a medicine between a medicine container and a syringe by the syringe, the medicine transfusion apparatus comprising:
- a medicine cassette that holds the medicine container;
- a lifting unit that moves the medicine cassette upward and downward between a middle position on an upper portion and a lower position of a main body along an arcuate path while maintaining a horizontal attitude of the medicine cassette using a pair of parallel link mechanisms;
- a first holding portion that is capable of holding the syringe and is detachably mounted to the main body;
- a first driving unit that relatively moves the medicine cassette and the first holding portion so that a needle of the syringe held by the first holding portion is inserted into the medicine container;
- and
- a second driving unit that drives a plunger of the syringe to transfuse the medicine between the syringe and the medicine container.
A medicine transfusion method comprising:
- a first step of moving a medicine cassette holding a medicine container upward from a lower position of a main body to a middle position on an upper portion of the main body along an arcuate path while maintaining a horizontal attitude of the medicine cassette by a lifting unit utilizing a pair of parallel link mechanisms;
- a second step of reloading the medicine cassette from a first pedestal of the lifting unit to a second pedestal of a first driving unit in the middle position after the first step;
- a third step of inserting a needle of a syringe held by a first holding portion into the medicine container held by the medicine cassette after the second step;
- and
- a fourth step of driving a plunger of the syringe to transfuse a medicine between the syringe and the medicine container after the third step.
