Abstract

This disclosure relates to drug delivery methods and related products. In some aspects, a method includes selecting a drug vial combination by comparing a prescribed drug dosage to a dosing schedule, and delivering substantially all of the first drug from each of the selected drug vials to a patient by operating a pump of a drug delivery device to which the drug vials are connected.

Claims

1. A method, comprising:

selecting a drug vial combination by comparing a prescribed drug dosage to a dosing schedule, the dosing schedule providing a plurality of drug vial combinations associated with a plurality of drug dosages, wherein the selected drug vial combination comprises one or more drug vials, and each of the one or more drug vials contains a first drug; and

delivering substantially all of the first drug from each of the one or more drug vials to a patient by operating a pump of a drug delivery device to which the one or more drug vials are connected.

2. The method of claim 1, wherein a control unit of the drug delivery device selects the drug vial combination.

3. The method of claim 2, wherein the control unit runs a computer program that automatically selects the drug vial combination based on the prescribed dosage and operator preferences.

4. The method of claim 3, wherein the prescribed dosage and operator preferences are entered into the drug delivery device by the operator.

5. The method of claim 3, wherein the prescribed dosage is electronically transmitted to the control unit from a database storing data comprising the prescribed dosage.

6. The method of claim 5, wherein the prescribed dosage is entered into the database by or at the direction of a physician of the patient.

7. The method of claim 2, wherein the control unit controls operation of the pump.

8. The method of claim 1, wherein the drug vial combinations and associated drug dosages of the dosing schedule are based on a single treatment.

9. The method of claim 1, wherein the drug vial combinations and associated drug dosages of the dosing schedule are based on multiple treatments.

10. The method of claim 1, wherein the drug vial combination is selected based at least in part on the number of drug vials required over the course one or more treatments.

11. The method of claim 10, wherein the drug vial combination is selected based at least in part on the number of drug vials required over the course of multiple treatments.

12. The method of claim 11, wherein the drug vial combination is selected based in part on a drug dosage consistency that would be provided by the drug vial combination over the course of multiple treatments.

13. A method, comprising:

receiving by one or more computers data related to a prescribed drug dosage; and

determining by the one or more computers one or more recommended drug vial combinations by comparing the prescribed dosage to a dosing schedule, wherein each of the one or more recommended drug vial combinations comprises one or more drug vials, and the one or more drug vials of each of the one or more recommended drug vial combinations contain an amount of drug substantially equal to the prescribed dosage, and wherein the dosing schedule comprises data representing a plurality of drug vial combinations associated with a plurality of drug dosages.

14. The method of claim 13, further comprising displaying the one or more recommended drug vial combinations on a display.

15. The method of claim 13, wherein determining the one or more recommended drug vial combinations comprises determining the one or more drug vial combinations from the dosing schedule that utilize the fewest drug vials over the course of one or more treatments and that contain an amount of drug substantially equal to the prescribed drug dosage.

16. The method of claim 15, wherein determining the one or more recommended drug vial combinations further comprises determining the one or more drug vial combinations from the dosing schedule that utilize the fewest drug vials over the course of multiple treatments and that contain an amount of drug substantially equal to the prescribed drug dosage.

17. The method of claim 13, wherein determining the one or more recommended drug vial combinations comprises determining one or more drug vial combinations from the dosing schedule that result in a drug dosage consistency within an acceptable consistency range over the course of one or more treatments and that contain an amount of drug substantially equal to the prescribed drug dosage.

18. The method of claim 17, wherein determining the one or more recommended drug vial combinations further comprises determining the one of the one or more drug vial combinations that utilizes the fewest number of drug vials over the course of the one or more treatments and that contains an amount of drug substantially equal to the prescribed drug dosage.

19. The method of claim 13, wherein determining the one or more recommended drug vial combinations comprises determining one or more drug vial combinations from the dosing schedule that result in a drug dosage consistency within an acceptable consistency range over the course of multiple treatments and that contain an amount of drug substantially equal to the prescribed drug dosage.

20. The method of claim 19, wherein determining the one or more recommended drug vial combinations further comprises determining the one of the one or more drug vial combinations from the dosing schedule that utilizes the fewest number of drug vials over the course of the multiple treatments and that contains an amount of drug substantially equal to the prescribed drug dosage.

21. The method of claim 13, wherein determining the one or more recommended drug vial combinations comprises determining the drug vial combination from the dosing schedule that provides the greatest drug dosage consistency over the course of the one or more treatments and that contains an amount of drug substantially equal to the prescribed drug dosage.

22. The method of claim 21, wherein determining the one or more recommended drug vial combinations comprises determining the drug vial combination that provides the greatest drug dosage consistency over the course of multiple treatments and that contains an amount of drug substantially equal to the prescribed drug dosage.

23. The method of claim 13, wherein the data is transmitted from a user interface of a medical system.

24. The method of claim 23, wherein the medical system is a hemodialysis system.

25. The method of claim 13, wherein the one or more computers is a processor.

26. A computer program product residing on a computer readable medium, the computer program product comprising instructions for causing a processor to:

determine one or more recommended drug vial combinations by comparing a prescribed dosage to a dosing schedule, wherein each of the one or more recommended drug vial combinations comprises one or more drug vials, and the one or more drug vials of each of the one or more recommended drug vial combinations contain an amount of drug substantially equal to the prescribed dosage, and wherein the dosing schedule comprises data representing a plurality of different drug vial combinations associated with a plurality of different drug dosages.
