Method for controlling a drug dispensing system
View Patent ↗An automated drug dispensing system includes a cabinet adapted to store a variety of prepackaged pharmaceuticals in a plurality of bins for filling patient prescriptions. Each bin stores a particular variety of packaged multiple-dose pharmaceutical. Each variety of pharmaceutical is associated with a particular code. A controller receives request signals and in response generates dispense signals. Each bin includes a dispenser coupled to the controller for dispensing the packaged pharmaceuticals therefrom in response to a dispense signal sent from the controller. After a package is dispensed, a code reader determines the code of the dispensed package and verifies whether the code on the dispensed package matches the code of the requested package.
1. A method of dispensing medication to a patient at a selected drug dispensing unit, comprising the steps of:
receiving, at a first location, a request to supply a patient with at least one package containing a drug prescribed by a physician;
validating the request received during said receiving step to ensure the patient is authorized to receive a prescribed medication;
providing a patient authorized to receive a prescribed medication with a unique identifier; and
in response to entry of the unique identifier at a second location remotely disposed relative to the first location, causing a drug dispensing unit to dispense the medication specified in the request received during the receiving step for distribution to the patient.
2. The method of claim 1 , further including the step of accepting payment from the patient by debiting a credit card account.
3. The method of claim 1 , wherein said step of accepting payment is performed at said first location.
4. The method of claim 1 , wherein said step of accepting payment is performed at said second location.
5. The method of claim 1 , further including a step of identifying the amount of delay permissible before a patient must receive a drug identified in a request received during the receiving step.
6. The method of claim 5 , where said receiving step includes receiving a request for a drug via one of a data transmission network, a facsimile transmission, or by mail, further including a step of supplying a drug identified in the received request by one of regular mail and express courier in the event a permissible delay exceeding an applicable threshold identified during said step of identifying.
7. The method of claim 1 , comprising a step of storing, at each of a plurality of prescription medication dispensing units remotely located from one another, an inventory of frequently prescribed medications including at least some drugs which a patient is advised to take as soon as practicable after issuance of a prescription by a physician.
8. The method of claim 7 , wherein the drugs stored during the storing step are in a form selected from the group consisting of solids, liquids, ointments, and creams.
9. The method of claim 1 , wherein said step of causing a drug dispensing unit to dispense comprises transmitting, from the drug dispensing unit, a signal representative of an entered key code to a remote controller operative to associate a corresponding patient identification key code with a particular validated prescription.
10. The method of claim 1 , further including a step of storing, for each request to dispense a drug, an encrypted enabling signal and a corresponding transaction key code unique to each particular request for decrypting instructions for filling a request at the dispensing unit, wherein in response to receipt of the signal transmitted during said transmitting step, the remote controller performs a step of transmitting the encrypted enabling signal and transaction key code to the prescription medication dispensing unit when a corresponding math is identified, said dispensing unit being responsive to receipt of the enabling signal and transaction key code to decode instructions for filling a request and to dispense a corresponding drug in accordance with said decoded instructions.
11. The method of claim 1 , further comprising a step of establishing a communication link between a pharmacist at a centralized location and a patient disposed proximate a remote drug dispensing unit, said drug dispensing unit containing a plurality of drugs available by physician prescription; wherein said step of remotely operating is performed from the centralized location, the drug dispensing unit being responsive to remotely transmitted commands so as to dispense to the patient a drug specified in the request received during the receiving step.
