Abstract

An automated medication preparation system for preparing a prescribed dosage of medication in a drug delivery device includes a plurality of stations for receiving, handling and processing the drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device. At least one of the stations includes a peripheral device for performing at least one operation and a transporting device that receives and holds more than one drug delivery device and moves the drug delivery devices in a controlled manner from one station to another station. The system includes a master controller that tracks and controls the movement of the transporting device and operation of equipment at one or more stations. In addition, a system further includes a Bluetooth communications network between the peripheral device and the master controller such that that the peripheral device automatically communicates with the controller when the peripheral device is within a predetermined distance from the controller.

Claims

1. A method of operating an automated medication preparation system to prepare and deliver a prescribed dosage of medication to a drug delivery device comprising the steps of:

inputting a drug order that contains instructions for forming the prescribed dosage of medication;

providing a plurality of stations for receiving, handling and processing a drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device, wherein at least one of the stations includes a peripheral device for performing at least one operation;

operating a transporting device that receives and holds more than one drug delivery device such that each drug delivery device moves in a controlled manner from one station to another station;

communicating with the peripheral device by means of a Bluetooth communications network to monitor a status of the at least one operation performed at the peripheral device; and

delivering, in an automated manner, the prescribed dosage of medication to the drug delivery device in conformity with the drug order.

2. An automated medication preparation system for preparing a prescribed dosage of medication in a drug delivery device comprising:

a plurality of stations for receiving, handling and processing the drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device, wherein at least one of the stations includes a peripheral device for performing at least one operation;

a transporting device that receives and holds more than one drug delivery device and moves the drug delivery devices in a controlled manner from one station to another station;

a master controller that tracks and controls the movement of the transporting device and operation of equipment at one or more stations; and

a Bluetooth communications network between the peripheral device and the master controller such that the peripheral device automatically communicates with the controller when the peripheral device is within a predetermined distance from the controller, wherein the Bluetooth communications network includes a first Bluetooth component that is operatively coupled to the master controller and a second Bluetooth component that is operatively coupled to the peripheral device, the two Bluetooth components in automatic communication with one another;

wherein the system is configured so that two or more separate drug delivery devices are acted upon at the same time at two or more different stations.

3. The system of claim 2, wherein the peripheral device comprises an automated bagger machine that receives filled drug delivery devices and seals one or more in a bag structure.

4. The system of claim 2, wherein the controller includes software that provides a virtual communications port that sends an arbitrary signal to the second Bluetooth component and if a connection is established between the peripheral device and the master controller, the arbitrary signal is echoed back to the controller, thereby immediately indicating that the second Bluetooth component is operating, and wherein if the arbitrary signal is echoed back, second Bluetooth device is receiving no power, thereby indicating a malfunction at the peripheral device.

5. The system of claim 2, wherein the periphery device is configured so that when a malfunction results, power to the second Bluetooth component is cut off resulting in the first Bluetooth component not receiving a signal echo, thereby instructing the master controller of the occurrence of a malfunction at the peripheral device.

6. The system of claim 2, wherein the peripheral device comprises an automated bagger apparatus for bagging and sealing one more drug delivery devices and the controller is programmed to check the status of the Bluetooth communications network to see if all of the Bluetooth devices are powered up before placing the drug delivery device on a mechanism for delivering a filled drug delivery device from one station to the peripheral device and if a malfunction is detected, the drug delivery device is not delivered to the peripheral device.

7. The system of claim 2, wherein the peripheral device comprises a labeler device that is in wireless communication with the master controller by means of a first Bluetooth component that is operatively coupled to the master controller and a second Bluetooth component that is operatively coupled to the peripheral device, wherein the controller is alerted to a malfunction of the peripheral device and the master controller influences the operation on the drug delivery device by the peripheral device.

8. The system of claim 2, wherein the Bluetooth communications network includes a first Bluetooth component that is operatively coupled to the master controller and a second Bluetooth component that is operatively coupled to the peripheral device, the peripheral device having a local controller that is in communication with the second Bluetooth component and is configured to generate an error signal when a malfunction or error is observed at the peripheral device, the error signal uniquely identifying the type of error that is observed, the unique error signal being delivered to the second Bluetooth component and then wirelessly transmitted to the first Bluetooth component which delivers the error signal to the master controller which then takes one or more remedial actions.

9. The system of claim 2, wherein the master controller monitors a status of communication in the Bluetooth communications network prior to advancing the drug delivery device to the peripheral device and if there is a break in communication with the peripheral device, the master controller prevents delivery of the drug delivery device to the peripheral device and generates an error message.

10. The system of claim 2, wherein the second Bluetooth component is configured so that when the peripheral device has a change in its operating state or mode, communication between the first and second Bluetooth components is altered resulting in the master controller being alerted to this change at the peripheral device.

11. The system of claim 2, wherein the peripheral device is configured so that once it is reset, the first and second Bluetooth components communicate with one another in a normal operation mode that is indicative of the peripheral device being free of malfunction and operating in a normal mode.

12. An automated medication preparation system for preparing a prescribed dosage of medication in a drug delivery device comprising:

a plurality of stations for receiving, handling and processing the drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device, wherein at least one of the stations includes a peripheral device for performing at least one operation;

a transporting device that receives and holds more than one drug delivery device and moves the drug delivery devices in a controlled manner from one station to another station;

a master controller that tracks and controls the movement of the transporting device and operation of equipment at one or more stations;

a Bluetooth communications network between the peripheral device and the master controller such that the peripheral device automatically communicates with the controller when the peripheral device is within a predetermined distance from the controller;

wherein the system is configured so that two or more separate drug delivery devices are acted upon at the same time at two or more different stations and wherein the transporting device comprises a cam-indexed device that receives and releasably holds each drug delivery device as it is controllably advanced from one station to a next station.
