Abstract

A method of dispensing medicaments may employ a drug dispensing device comprised of an upper hopper having an upper opening for receiving a medicament and a lower opening. The drug dispensing device also includes a lower hopper having an upper opening and a lower opening in a bottom portion thereof. The upper hopper defines a bulk storage chamber and the lower hopper defines a dispensing chamber. A rotatable dispensing disc is positioned in a lower portion of the dispensing chamber for dispensing medicament from the drug dispensing device through the lower opening in the lower hopper. A regulator is situated between the bulk storage chamber and the dispensing chamber for controlling the rate at which medicament moves from the storage chamber to the dispensing chamber.

Claims

1. A method, comprising:

storing in a bulk storage chamber a volume of medicament;

dispensing said medicament from a dispensing chamber; and

regulating a rate at which medicament is fed from said storage chamber to said dispensing chamber.

2. The method of claim 1 additionally comprising the step of priming said dispensing chamber with a volume of medicament from said storage chamber before said dispensing.

3. The method of claim 1 wherein said dispensing is performed by rotating a rotatable dispensing disc positioned in said dispensing chamber.

4. The method of claim 1 wherein said regulating is performed in conjunction with said rotating.

5. The method of claim 1 wherein said dispensing is performed in response to a volume of medicament in said dispensing chamber.

6. A method according to claim 1 wherein regulating a feed rate comprises positioning a regulator between the bulk storage chamber and the dispensing chamber.

7. A method according to claim 6 wherein the regulator comprises a metering section defining a plurality of differently sized feed openings and a selection plate defining at least one selection opening, and wherein regulating a feed rate further comprises aligning the at least one selection plate with a respective feed opening while blocking all other feed openings.

8. A method, comprising:

storing a volume of medicament in a bulk storage chamber having an exit opening;

dispensing said medicament from a dispensing chamber which has an entrance opening; and

controlling an amount by which at least one of the exit opening of the bulk storage chamber or the entrance opening of the dispensing chamber is restricted.

9. The method according to claim 8 additionally comprising the step of priming said dispensing chamber with a volume of medicament from said storage chamber before said dispensing.

10. The method according to claim 8 wherein said dispensing is performed by rotating a rotatable dispensing disc positioned in said dispensing chamber.

11. The method according to claim 8 wherein said dispensing is performed in response to a volume of medicament in said dispensing chamber.

12. A method according to claim 8 wherein controlling the amount comprises positioning a regulator between the bulk storage chamber and the dispensing chamber.

13. A method according to claim 12 wherein the regulator comprises a metering section defining a plurality of differently sized feed openings and a selection plate defining at least one selection opening, and wherein controlling the amount further comprises aligning the at least one selection plate with a respective feed opening while blocking all other feed openings.
