Abstract

Described herein are methods and systems for automated dispensing of individual medicament portions. The systems can include a housing that encloses a receiving space having a bottom surface. A separation device may be provided and arranged on the bottom surface with at least one channel to receive at least one medicament portion. At least one channel may have an opening facing the receiving space and an opening facing the bottom surface. The opening facing the bottom surface may be associated with a contact area on the bottom surface, over which contact area the medicament portions may be guided upon a movement of separation device. At least one recess may be arranged in the bottom surface outside of the contact area to receive contamination particles present in the container.

First claim

What is claimed is:

1. A storage container for automated dispensing of individual medicament portions, comprising:
a housing, enclosing a receiving space and having a bottom surface;
a separation device arranged on the bottom surface with at least one channel to receive at least one medicament portion, wherein the at least one channel has a first opening facing the receiving space and a second opening facing the bottom surface and the second opening is associated with a contact area on the bottom surface, over which contact area the medicament portions are guided upon a movement of the separation device;
at least one recess arranged in the bottom surface outside of the contact area to receive contamination particles present in the storage container;
a rotor arranged on the bottom surface comprising a channel configured to separate an individual medicament portion when the rotor turns by a selected angle, the rotor further comprising a plurality of cleaning agents separated by the channel at its side facing the bottom surface, the plurality of cleaning agents configured to feed the contamination particles to the at least one recess when the rotor turns by the selected angle; and
a vibration device coupled to a contact area adjacent to the bottom surface, the vibration device configured to:
expose the housing to a vibration, and
direct the contamination particles towards the at least one recess by gravity, upon actuation of the vibration device.

2. The storage container of claim 1 , wherein the rotor is arranged to provide a gap between a bottom of the rotor and the bottom surface, through which gap contamination particles can pass.

3. The storage container of claim 2 , wherein:
at least one section of the bottom surface comprises a funnel-shaped section and the rotor is arranged in a center of the funnel-shaped section; and
at least one recess formed in the bottom surface is arranged between the center of the funnel-shaped section and the contact area.

4. The storage container of claim 3 , wherein the at least one recess is formed as a coaxial groove with respect to a rotor axis.

5. The storage container of claim 2 , wherein the cleaning agents are aligned outwardly at the bottom of the rotor at an angle configured to sweep the contamination particles into the recess when the rotor turns by the selected angle.

6. The storage container of claim 2 , further comprising a circular protrusion coaxial to a rotor axis, the circular protrusion formed on the bottom surface, wherein the at least one recess is arranged outside of the bottom surface, and the bottom surface is enclosed by the circular protrusion.

7. The storage container of claim 1 , wherein at least one section of the bottom surface is coated with a non-stick coating.

8. The storage container of claim 1 , wherein the vibration device is mechanically coupled to the contact area in the housing.

9. An apparatus for dispensing individual medicament portions comprising:
a housing having a dispensing opening;
a storage container configured to store a plurality of medicament portions;
a rotor having a plurality of channels, wherein each of the channels is configured to dispense an individual medicament portion when the rotor turns by a selected angle;
a bottom surface in the storage container including a recess configured to collect contamination particles, the bottom surface having a funnel shape to direct the contamination particles to the recess, wherein the rotor comprises a plurality of cleaning agents separated by the plurality of channels at its side facing the bottom surface, the plurality of cleaning agents configured to feed contamination particles to the recess when the rotor turns by the selected angle;
a retention component configured to engage with an aligned channel to prevent a second individual medicament portion to be dispensed together with the individual medicament portion when only one medicament portion is dispensed; and
a vibration device coupled to a contact area adjacent to the bottom surface and configured to:
expose the housing to a vibration, and
direct the contamination particles towards the recess by gravity, upon actuation of the vibration device.

10. The apparatus of claim 9 , wherein the channels are arranged at an outer circumference of the rotor and are open outwardly.

11. The apparatus of claim 9 , wherein the housing has a corresponding cylindrical section with a diameter larger than an outer diameter of the rotor, to accept the rotor.

12. The apparatus of claim 9 , wherein the recess forms a coaxial groove with respect to a rotor axis.

13. The apparatus of claim 9 , wherein the recess forms a circular section, and an angular portion of the bottom surface interrupts the circular section of the recess.

14. The apparatus of claim 9 , wherein the cleaning agents are aligned outwardly at a bottom side of the rotor, at an angle configured to sweep the contamination particles into the recess when the rotor turns by the selected angle.

15. A method for dispensing individual medicament portions, comprising:
storing medicament portions in a receiving space formed between a housing section and a rotor at a center of a bottom surface of the housing section;
aligning an opening in the bottom surface of the housing section with a channel formed on the rotor;
exposing the housing section to a vibration by a vibration device mechanically coupled to a contact area adjacent to the bottom surface;
directing contamination particles towards a recess by gravity when the housing section is exposed to the vibration and by a push from a plurality of cleaning agents at a side of the rotor facing the bottom surface when the rotor turns; and
dispensing the individual medicament portion to a packaging machine via a container intake.

16. The method as in claim 15 , wherein directing contamination particles towards a recess comprises pushing the contamination particles to move to the recess through a gap formed between a bottom of the rotor and an upper side of the bottom surface of the housing section with at least one of the plurality of cleaning agents oriented outwardly in a direction of rotation of the rotor.

17. The method as in claim 15 , further comprising vibrating the receiving space when a packaging device does not blister to avoid dispensing of a medicament portion to a defective package.

18. The method as in claim 15 , wherein aligning the opening in the bottom surface of the housing section with a channel formed on the rotor comprises rotating the rotor by a selected angle.

19. The method as in claim 15 , further comprising preventing a second medicament portion to be dispensed through the channel simultaneously with the individual medicament portion, when only one medicament portion is dispensed of a drug logistic.

20. The method as in claim 19 , wherein preventing a second medicament portion comprises partially engaging and blocking the channel formed in the rotor with a retention component.
