Abstract

Method and system for providing an integrated analyte monitoring system and on-body patch pump with multiple cannulas and a sensor combination is provided.

Claims

1. An integrated therapy management system, comprising:

a housing comprising a unidirectional connector port;

a first cannula for transcutaneous placement under a skin layer of a patient at a first infusion site for a first time period, the first cannula connected to a reservoir at a first location;

a second cannula for transcutaneous placement under the skin layer of the patient at a second infusion site for a second time period, the second cannula connected to the reservoir at a second location and connected to the housing by an infusion tubing coupled to the port;

wherein the first location and the second location are different; and

an analyte sensor configured for fluid contact with an analyte of the patient for a predetermined time period;

wherein the first cannula and the second cannula are configured to deliver a therapeutic agent from the reservoir to the patient during the predetermined time period.

2. The system of claim 1, wherein the first cannula, the second cannula, and the sensor are coupled to the housing.

3. The system of claim 1, wherein the first cannula and the sensor are coupled to the housing.

4. The system of claim 1, wherein the first infusion site and the second infusion site are separated by a predetermined distance.

5. The system of claim 1, wherein when the second cannula is transcutaneously positioned, the first cannula is withdrawn from the first infusion site.

6. The system of claim 1, wherein the sensor includes an analyte sensor.

7. The system of claim 1, wherein the therapeutic agent includes insulin.

8. The system of claim 1, wherein the first cannula is within an interior of the housing and the second cannula is external to the interior of the housing.

9. The system of claim 1, wherein the integrated therapy management system further comprises a pre-filled pouch.

10. The system of claim 1, wherein the integrated therapy management system further comprises a leakage sensor.

11. An integrated therapy management system, comprising:

an on-body micropump including;

a housing comprising a unidirectional connector port,

a first cannula for transcutaneous placement under a skin layer of a patient at a first infusion site for a first time period, the first cannula connected to a reservoir at a first location,

a second cannula for transcutaneous placement under the skin layer of the patient at a second infusion site for a second time period, the second cannula connected to the reservoir at a second location, and connected to the housing by an infusion tubing coupled to the port,

wherein the first location is different than the second location, and

an analyte sensor configured for fluid contact with an analyte of the patient for a predetermined time period; and

a controller in signal communication with the on-body micropump, the controller configured to transmit one or more signals to the micropump to control the delivery of a therapeutic agent from the reservoir to the patient using one or more of the first cannula and the second cannula.

12. The system of claim 11, wherein the micropump further includes a transmitter unit operatively coupled to the analyte sensor.

13. The system of claim 12, wherein the controller is configured to receive one or more signals associated with one or more analyte levels of the patient from the transmitter unit.

14. The system of claim 13, wherein the controller is further configured to receive one or more signals associated with the therapeutic agent delivery.

15. An integrated therapy management system, comprising:

a housing comprising a unidirectional connector port;

a first cannula for transcutaneous placement under a skin layer of a patient at a first infusion site for a first time period, the first cannula connected to a first reservoir;

a second cannula for transcutaneous placement under the skin layer of the patient at a second infusion site for a second time period, the second cannula connected to a second reservoir; and

an analyte sensor configured for fluid contact with an analyte of the patient for a predetermined time period;

wherein the first cannula and the second cannula are configured to deliver a therapeutic agent to the patient during the predetermined time period directly from the first reservoir and the second reservoir.

16. The system of claim 15, wherein when the second cannula is transcutaneously positioned, the first cannula is withdrawn from the first infusion site.

17. The system of claim 15, wherein the sensor includes an analyte sensor.

18. The system of claim 15, wherein the therapeutic agent includes insulin.

19. The system of claim 15, wherein the first cannula, the second cannula and the sensor are coupled to the housing.
