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:

1. A storage and dispensing device, comprising:
a housing;
a rotor, the rotor comprising multiple channels arranged about a circumference of the rotor, a first channel configured to separate an individual medicament portion from a plurality of stored medicament portions when the rotor turns a predetermined amount;
a medicament dispensing opening disposed in a bottom surface of the housing and configured to receive the individual medicament portion when the first channel is aligned with the medicament dispensing opening;
a stop element comprising an elastic arm configured to engage with a toothed profile formed in the axis of the rotor and to avoid an unintended rotation of the rotor; and
a recess disposed in the bottom surface of the housing and at least partially surrounding an axis of the rotor.

2. The device of claim 1 , wherein the multiple channels are separated by multiple webs that overlap a contact area on the bottom surface, the contact area being exposed to the medicament portions through the channels, and wherein the medicament dispensing opening intersects the contact area to receive the individual medicament portion as the medicament portions are swept by the webs upon a rotation of the rotor.

3. The device of claim 1 , further comprising a retention component configured to engage with a channel aligned with an opening of the housing, and to prevent a second individual medicament portion to be dispensed through the channel aligned with the opening of the housing.

4. The device of claim 1 , wherein each of the channels comprises a first opening facing the plurality of stored medicament portions and a second opening facing the bottom surface, wherein the second opening is associated with a contact area on the bottom surface, and wherein the device is configured to guide medicament portions over the contact area upon a movement of the rotor.

5. The device of claim 1 , wherein the rotor further comprises multiple cleaning agents separated by the channels, the multiple cleaning agents formed on a side of the rotor facing the bottom surface and aligned outwardly at an angle configured to sweep a contamination particle into the recess when the rotor turns by the predetermined amount.

6. The device of claim 1 , further comprising a vibration device mechanically coupled to a contact area adjacent to the bottom surface, the vibration device configured to:
expose the housing to a vibration, and
direct a contamination particle towards the recess by gravity upon actuation of the vibration device.

7. The device 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.

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

9. The device of claim 1 , further comprising a protrusion at least partially surrounding the axis of the rotor, the protrusion configured to prevent contamination particles from reaching the axis of the rotor.

10. A method, comprising:
separating, by a channel of a rotor, an individual medicament portion from multiple medicament portions stored in a receiving space defined by a housing and the rotor;
aligning the channel containing the individual medicament portion with an opening in a bottom surface of the housing;
dispensing the individual medicament portion to a packaging machine; and
directing contamination particles into a recess disposed in the bottom surface of the housing and at least partially surrounding an axis of the rotor.

11. The method of claim 10 , further comprising engaging a retention component with the channel to prevent a second individual medicament portion from being delivered.

12. The method of claim 10 , further comprising aligning a second channel of the rotor with the opening in the bottom surface of the housing to dispense a second individual medicament portion to the packaging machine.

13. The method of claim 10 , further comprising engaging a toothed portion of the axis of the rotor with an elastic arm from a stop mechanism anchored on the opening in the bottom surface to prevent an unintended dispensing of the individual medicament portion.

14. The method of claim 10 , wherein channel of the rotor with the opening in the bottom surface of the housing comprises sweeping the individual medicament portion over a contact area formed between the bottom surface and the rotor with a web separating the channel formed on the rotor with a second channel formed on the rotor, the second channel containing a second individual medicament portion.

15. The method of claim 10 , further comprising:
exposing the housing to a vibration by a vibration device mechanically coupled to a contact area adjacent to the bottom surface of the housing; and
directing contamination particles towards the recess by gravity when the housing 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.

16. The method of claim 10 , wherein directing contamination particles towards the 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 with a cleaning agent formed on a bottom face of the rotor and oriented outwardly in a direction of rotation of the rotor.

17. The method of claim 10 , wherein aligning the channel of the rotor with the opening in the bottom surface of the housing comprises rotating the rotor by a selected angle.

18. The method of claim 10 , further comprising preventing a second medicament portion to be dispensed through the channel simultaneously with the individual medicament portion.

19. The method of claim 10 , further comprising preventing, by a protrusion at least partially surrounding the axis of the rotor, the contamination particles from reaching the axis of the rotor.
