View Patent ↗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.
1. A method, comprising: storing in a bulk storage chamber a volume of a prescription drug to be used to fill individual prescriptions; dispensing said prescription drug from a dispensing chamber which is configured to store and dispense a plurality of units of the prescription drug as directed by a controller; and regulating a feed rate at which the prescription drug is fed from said storage chamber to said dispensing chamber, wherein regulating the feed rate comprises positioning a regulator between the bulk storage chamber and the dispensing chamber;
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.
2. The method of claim 1 additionally comprising the step of priming said dispensing chamber with a volume of prescription drug 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 3 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 prescription drug in said dispensing chamber.
6. A method, comprising: storing a volume of a prescription drug in a bulk storage chamber having an exit opening; dispensing said prescription drug from a dispensing chamber which has an entrance opening and is configured to store and dispense a plurality of units of the prescription drug; 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, the controlling comprising positioning a regulator between the bulk storage chamber and the dispensing chamber;
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 opening with a respective feed opening while blocking all other feed openings.
7. The method according to claim 6 additionally comprising the step of priming said dispensing chamber with a volume of prescription drug from said storage chamber before said dispensing.
8. The method according to claim 6 wherein said dispensing is performed by rotating a rotatable dispensing disc positioned in said dispensing chamber.
9. The method according to claim 6 wherein said dispensing is performed in response to a volume of prescription drug in said dispensing chamber.
