Abstract

A medicine mixing device includes a pedestal, a main rotating-base, a sub rotating-base, and a control unit. The pedestal is used to place medicine containers thereon. The main rotating-base includes a holding portion and a main rotating shaft, and rotates around the main rotating shaft. The holding portion holds a syringe for sucking a medicine at its center on its vertical plane. The main rotating shaft is orthogonal to the vertical plane. The sub rotating-base is disposed close to a part of the circumference of the main-rotating base and rotates relatively with respect to the main rotating-base. The sub rotating-base includes a fixing unit and a sub rotating shaft parallel to the main rotating shaft. The fixing unit fixes thereto one medicine container selected from the medicine containers on the pedestal. The control unit controls a medicine to be sucked out of the medicine container into the syringe.

Claims

1. A medicine mixing device comprising:

a pedestal on which medicine containers are to be placed;

a main rotating base including a holding portion and a main rotating shaft, and being rotatable around the main rotating shaft, the holding portion being configured to hold a syringe that sucks a medicine at a center thereof on a vertical plane thereof, and the main rotating shaft being orthogonal to the vertical plane;

a sub rotating base placed on the main rotating base and being rotatable relatively with respect to the main rotating base, the sub rotating base including a fixing unit and a sub rotating shaft parallel to the main rotating shaft, the fixing unit being configured to fix thereto one medicine container selected from the medicine containers on the pedestal; and

a control unit configured to control a medicine to be sucked out of the fixed medicine container into the syringe.

2. The medicine mixing device of claim 1, wherein

the medicine containers include a first medicine container and a second medicine container.

3. The medicine mixing device of claim 2, wherein

the first medicine container is a vial, and the second medicine container is an ampule.

4. The medicine mixing device of claim 1, further comprising:

an infusion holder configured to hold an infusion bag, the infusion holder including a transfer mechanism that moves the infusion bag with respect to the syringe.

5. The medicine mixing device of claim 1, wherein

the fixing unit of the sub rotating base includes a retention mechanism that holds the medicine container such that a center of the medicine container coincides with a needle of the syringe.

6. The medicine mixing device of claim 1, wherein

the holding portion of the main rotating base includes a transfer mechanism movable in an axial direction.

7. The medicine mixing device of claim 1, wherein

the fixing unit of the sub rotating base includes a transfer mechanism movable in an axial direction.

8. The medicine mixing device of claim 1, wherein

the pedestal is one of a rectilinear rack and a turntable.

9. The medicine mixing device of claim 8, wherein

the turntable includes a revolver having a motor at a bottom thereof, the turntable being driven by the revolver.

10. The medicine mixing device of claim 8, wherein

the one of the rectilinear rack and the turntable is detachable and portable.
