Abstract

Devices dispense medicine and dietary supplements in solid dosage form. The dimensions of the selection slots for the solid dosage forms in a device can be customized in depth by adding or subtracting spacers, and in width by adding or subtracting thickness inserts, or otherwise by employing components of suitable dimensions. Also, structures and methods for resolving jams of solid dosage forms are disclosed.

Claims

1. A method of dispensing a single solid dosage form, comprising:

(a) obtaining a device that comprises

a storage compartment storing a plurality of solid dosage forms having a same shape; and

a receiver coupled to the storage compartment and adapted to rotate about an axis, comprising a selection slot at a distance from the axis, wherein the selection slot is adapted to separate a single solid dosage form from the plurality of solid dosage forms when the receiver is selectively rotated clockwise and counterclockwise about the axis, and wherein the receiver is reversibly coupled to at least one spacer in a manner that lengthens a dimension of the selection slot to accommodate the same shape in the selection slot;

(b) rotating in a first direction the receiver about the axis;

(c) determining that the selection slot has not separated the single solid dosage form from the plurality;

(d) rotating in a second direction the receiver about the axis;

(e) optionally repeating one or more of the (b) rotating in a first direction, the (c) determining, and the (d) rotating in a second direction; and

(f) detecting that the selection slot has separated the single solid dosage form from the plurality;

(g) dispensing the single solid dosage form from the device;

wherein the storage compartment further comprises a sweeper coupled to the storage compartment and adjustably positioned proximate to the selection slot of the receiver to aid the selection slot to separate the single solid dosage form when the receiver is (b) rotating in the first direction and (d) rotating in the second direction;

thereby dispensing the single solid dosage form.

2. The method of claim 1, wherein the receiver comprises a selection slot selector reversibly coupled to a selection slot carrier, wherein the selection slot carrier comprises a plurality of selection slots of different dimensions.

3. The method of claim 1, wherein the (c) determining and the (f) detecting comprises employing a detector to detect whether the selection slot has separated the single solid dosage form.

4. The method of claim 3, wherein the detector comprises an electromechanical switch, a laser diode, a fiberoptic array, a photoanode, or a combination of two or more thereof.

5. The method of claim 1, wherein the receiver is reversibly coupled to at least one thickness insert to accommodate the same shape in the selection slot.

6. The method of claim 1, wherein the receiver is substantially circular.

7. The method of claim 1, wherein the selection slot is located at an edge of the receiver.

8. The method of claim 1, wherein the selection slot comprises a guiding portion adapted to introduce the single solid dosage form into the selection slot, and a transporting portion adapted to move the single solid dosage form away from the plurality of solid dosage forms.

9. The method of claim 1, wherein the receiver further defines a convex surface adapted to direct solid dosage forms from the plurality toward the selection slot.

10. A method for dispensing two or more unique solid dosage forms from a collection of unique solid dosage forms,

wherein a unique solid dosage form in the collection has a shape that is independently alike or different from other unique solid dosage forms in the collection,

wherein the method comprises:

(a) obtaining a device that comprises

storage compartments, each storage compartment storing a plurality of a unique solid dosage form separately from other unique solid dosage forms, and comprising a receiver

coupled to the storage compartment,

adapted to rotate about an axis,

comprising a selection slot at a distance from the axis,

wherein the receiver is reversibly coupled to

at least one spacer in a manner that lengthens a dimension of the selection slot to accommodate in the selection slot the shape of the unique solid dosage form stored in the storage compartment;

(b) selecting the two or more unique solid dosage forms from the collection to dispense, thereby identifying selected forms;

(c) for at least one storage compartment among the storage compartments,

(i) rotating in a first direction the receiver about the axis;

(ii) determining that the selection slot has not separated a single selected form from the plurality;

(iii) rotating in a second direction the receiver about the axis;

(iv) optionally repeating one or more of the (i) rotating in a first direction, the (ii) determining, and the (iii) rotating in a second direction; and

(v) detecting that the selection slot has separated the single selected form from the plurality;

wherein the at least one storage compartment further comprises a sweeper coupled to the at least one storage compartment and adjustably positioned proximate to the selection slot of the receiver to aid the selection slot to separate the single selected form when the receiver is (c)(i) rotating in the first direction and (c)(ii) rotating in the second direction;

(d) for at least one other of the storage compartments storing the selected forms,

(i) rotating in a third direction the receiver about the axis, wherein the third direction is independently alike or different from the first direction;

(ii) detecting that the selection slot has separated the single selected form from the plurality;

(e) optionally repeating one or both of (c) and (d) until all selected forms have been separated;

(f) dispensing all selected forms that have been separated;

thereby dispensing the two or more unique solid dosage forms.

11. The method of claim 10, wherein the receiver comprises a selection slot selector reversibly coupled to a selection slot carrier, wherein the selection slot carrier comprises a plurality of selection slots of different dimensions.

12. The method of claim 10, wherein the (c)(ii) determining and the (c)(v) detecting comprises employing a detector to detect whether the selection slot has separated the single selected form.

13. The method of claim 12, wherein the detector comprises an electromechanical switch, a laser diode, a fiberoptic array, a photoanode, or a combination of two or more thereof.

14. The method of claim 10, wherein the receiver is reversibly coupled to at least one thickness insert to accommodate the shape of the unique solid dosage form in the selection slot.

15. The method of claim 10, wherein the receiver is substantially circular.

16. The method of claim 10, wherein the selection slot is located at an edge of the receiver.

17. The method of claim 10, wherein the collection of unique solid dosage forms represents the weekly pharmaceutical and nutraceutical consumption of a patient.

18. The method of claim 10, wherein the (b) selecting represents a single pharmaceutical and nutraceutical consumption event of a patient.
