Abstract

A medication infusion device such as a programmable infusion pump includes data input regarding a selected patient parameter such as a current blood glucose reading. The infusion device includes a controller responsive to this data input to develop a medication delivery protocol which can be implemented automatically, recommended via a display for subsequent approval or rejection upon manipulation of control switches, or otherwise overridden in favor of a different medication delivery protocol.

Claims

1. A medication infusion device, comprising:

reservoir means for receiving and storing a supply of a selected medication;

delivery means for delivering a selected dosage of the medication from said reservoir means to a patient;

controller means for automatically controlling said delivery means to deliver the selected medication dosage to the patient according to a first medication dispensing protocol; and

means for inputting flood data to said controller means, said data being representative of a current patient condition parameter, said controller means including means responsive to said data for recommending a second medication dispensing protocol;

said controller means including patient accessible manual set means for enabling said controller means to deliver the medication to the patient according to a selected one of said first and second medication dispensing protocols.

2. The medication infusion device of claim 1 further including display means for displaying information pertaining to said selected one of said first and second medication dispensing protocols.

3. The medication infusion device of claim 1 wherein the patient condition parameter comprises a current blood glucose reading.

4. The medication infusion device of claim 3 wherein said device includes a housing having said reservoir means and said delivery means and said controller means mounted therein, said means for inputting data comprising a blood glucose sensor mounted on said housing.

5. The medication infusion device of claim 3 wherein said device includes a housing having said reservoir means and said delivery means and said controller means mounted therein, said means for inputting data comprising an in vivo sensor mounted on the patient and communicatively coupled to said controller means.

6. The medication infusion device of claim 5 wherein said in vivo sensor comprises an implanted sensor.

7. The medication infusion device of claim 5 wherein said in vivo sensor comprises a subcutaneous sensor.

8. The medication infusion device of claim 5 wherein said in vivo sensor is coupled to said controller means by telemetry.

9. The medication infusion device of claim 1 wherein said manual set means is further operable for enabling said controller means to deliver the medication according to a third manually inputted medication dispensing protocol.

10. A medication infusion device, comprising:

a housing having reservoir means for receiving and storing a supply of a selected medication;

delivery means on said housing for delivering a selected dosage of the medication from said reservoir means to a patient;

controller means for recommending one of a plurality of different medication dispensing protocols;

means for inputting flood data to said controller means, said data being representative of a current patient condition parameter, said controller means responding to said data to select the medication dispensing protocol to be recommended; and

display means on said housing for displaying the recommended medication dispensing protocol;

said delivery means being automatically operated by said controller means to deliver the selected medication dosage to the patient, said controller means being programmable for operating said delivery means according to a first medication dispensing protocol, said controller means being responsive to said data to recommend a second medication dispensing protocol, said controller means including patient accessible manual set means for enabling said controller means to deliver the medication to the patient according to a selected one of said first and second medication dispensing protocols.

11. The medication infusion device of claim 10, wherein said manual set means is further operable for enabling said controller means to deliver the medication according to a third manually inputted medication dispensing protocol.

12. The medication infusion device of claim 10 wherein said delivery means is manually operated by the patient.

13. The medication infusion device of claim 10 further including display means for displaying information pertaining to said medication dispensing protocol.

14. The medication infusion device of claim 13 wherein said means for inputting data comprising a blood glucose sensor mounted on said housing.

15. The medication infusion device of claim 13 wherein said means for inputting data comprises an in vivo sensor mounted on the patient and communicatively coupled to said controller means.

16. The medication infusion device of claim 15 wherein said in vivo sensor comprises an implanted sensor.

17. The medication infusion device of claim 15 wherein said in vivo sensor comprises a subcutaneous sensor.

18. The medication infusion device of claim 15 wherein said in vivo sensor is coupled to said controller means by telemetry.

19. In a medication infusion device having a reservoir for receiving and storing a supply of a selected medication, and delivery means for delivering medication from the reservoir to a patient, a method of operating said infusion device comprising the steps of:

automatically operating the delivery means to deliver a selected dosage of the medication to a patient according to a first medication dispensing protocol;

inputting flood data representative of a current patient condition parameter to a controller having a plurality of different medication dispensing protocols programmed therein;

responding to the inputted data to recommend a second medication dispensing protocol from the plurality programmed into the controller; and

operating the delivery means with patient accessible manual set means to deliver medication to the patient according to one of the first and second medication dispensing protocols or a different dispensing protocol.

20. The method of claim 19 further including displaying the recommended dispensing protocol.

21. The method of claim 19 wherein the patient condition parameter comprises a current blood glucose reading.
