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 device, comprising:
a rotor;
a housing, comprising:
an upper storage section;
a tilted storage section having a surface tilted toward the rotor;
a middle circular cylindrical section having a bottom surface;
a lower bottom section; and
a handle section,
wherein the upper storage section, the tilted storage section and the rotor define a receiving space configured to store multiple medicament portions,
wherein the rotor is disposed on a rotor axis coupled to the bottom surface of the middle circular cylindrical section, the rotor comprising multiple channels arranged about a circumference of the rotor, a channel included in the multiple channels configured to separate an individual medicament portion from the medicament portions when the rotor turns a predetermined amount; and

a medicament dispensing opening disposed in the bottom surface and configured to deliver the individual medicament portion by gravity when one of the channels is aligned with the medicament dispensing opening, wherein the bottom surface comprises a circular protrusion coaxial to the rotor axis, the circular protrusion configured to prevent contamination particles from converging toward a center area around the rotor axis.

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 deliver 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 stop element comprising an elastic arm configured to engage with a toothed profile formed in the rotor axis and to avoid an unintended rotation of the rotor.

4. 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.

5. The device of claim 1 , wherein each of the channels comprises a first opening facing the receiving space 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.

6. 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 a recess when the rotor turns by the predetermined amount.

7. 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 a recess concentric to the rotor axis by gravity, upon actuation of the vibration device.

8. 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.

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

10. A method, comprising:
storing multiple medicament portions in a receiving space of a housing defined by an upper storage section, a tilted storage section and a rotor disposed on a rotor axis within a middle circular cylindrical section of the housing;
separating an individual medicament portion from the multiple medicament portions;
aligning an opening in a bottom surface of the middle circular cylindrical section with a first channel of a plurality of channels formed on the rotor, the first channel containing the individual medicament portion;
dispensing the individual medicament portion to a packaging machine via a container intake;
engaging a retention component with the first channel to prevent a second individual medicament portion from being delivered; and
vibrating the receiving space when a packaging device does not blister to avoid dispensing of a medicament portion to a defective package.

11. The method of claim 10 , further comprising aligning the opening in the bottom surface of the middle circular cylindrical section with a second channel of the plurality of channels to dispense a second individual medicament portion to the packaging machine.

12. The method of claim 10 , wherein aligning the opening in the bottom surface of the middle circular cylindrical section with a channel formed on the rotor further comprises rotating the rotor about a rotor axis.

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

14. The method of claim 10 , wherein aligning the opening in the bottom surface of the middle circular cylindrical section with a channel formed on the rotor further 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; and
directing contamination particles towards a 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 as in claim 10 , 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 middle circular cylindrical section 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 as in claim 10 , wherein aligning the opening in the bottom surface of the middle circular cylindrical section with a channel formed on the rotor comprises rotating the rotor by a selected angle.

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