Abstract

Methods and systems for providing modular components in an integrated infusion device and analyte monitoring system where the components are independently replaceable are provided.

Claims

1. A modular system for providing integrated medication delivery and analyte level monitoring, comprising:

a replaceable first modular component configured to deliver medication, the first modular component comprising a connection port and a processing unit;

a replaceable second modular component configured to monitor an analyte level with a sensor tip portion, wherein the second modular component is connectable to the connection port of the first modular component to establish electrical contact between the sensor tip portion and the processing unit of the first modular component such that a signal corresponding to the analyte level passes from the sensor tip portion, through the connection port, and is received at the processing unit; and

a third modular component connectable to the connection port of the first modular component only when the second modular component is disconnected from the connection port, wherein the first modular component is operable when the third modular component is connected to the connection port of the first modular component;

wherein a first substantially water tight seal is formed at the connection port when the first and second modular components are connected, or a second substantially water tight seal is formed at the connection port when the first and third modular components are connected,

wherein the first modular component comprises a reusable portion and a disposable portion, the disposable portion including one or more of an infusion set or a reservoir containing the medication for delivery, and

wherein either of the second or third modular components are connectable to the reusable portion of the first modular component.

2. A modular system for providing integrated medication delivery and analyte level monitoring, comprising:

a replaceable first modular component configured to deliver medication, the first modular component comprising a connection port, a processing unit, and a tubular member configured to deliver medication at a first insertion site in a patient;

a replaceable second modular component comprising a sensor tip portion configured to detect an analyte level at a second insertion site in the patient, wherein the second modular component is connectable to the connection port of the first modular component to establish electrical contact between the sensor tip portion and the processing unit of the first modular component such that a signal corresponding to the analyte level passes from the sensor tip portion, through the connection port, and is received at the processing unit; and

a third modular component connectable to the connection port of the first modular component only when the second modular component is disconnected from the connection port, wherein the first modular component is operable when the third modular component is connected to the connection port of the first modular component;

wherein a first substantially water tight seal is formed at the connection port when the first and second modular components are connected, or a second substantially water tight seal is formed at the connection port when the first and third modular components are connected, and

wherein the first insertion site is associated with a first puncture and the second insertion site is associated with a second puncture different from the first puncture.

3. The system of claim 2, wherein one of the first modular component and the second modular component is configured for replacement independent of the other component.

4. The system of claim 2, wherein the third modular component includes a cap configured to couple to and directly contact the connection port of the first modular component.

5. The system of claim 2, wherein an analyte detected by the sensor tip is glucose.

6. The system of claim 2, wherein the first modular component includes a low profile medication infusion device.

7. The system of claim 2, wherein the first and second insertion sites are separated by a predetermined distance.

8. The system of claim 7, wherein the predetermined distance is less than approximately 12 inches.

9. The system of claim 2, wherein the first modular component includes a reusable portion and a disposable portion, wherein either of the second or third modular components are connectable to the reusable portion of the first modular component.

10. The system of claim 9, wherein the disposable portion of the first modular component includes one or more of an infusion set or a reservoir containing the medication for delivery.

11. The system of claim 9, wherein the processing unit is programmed to control the operation of one or more of the first modular component or the second modular component.

12. The system of claim 2, including a communication unit disposed in one or more of the first modular component or the second modular component, the communication unit configured to transmit to or receive data from a remote location.

13. The system of claim 12, wherein the remote location includes one or more of a portable control unit, a computer terminal, a server terminal, a mobile telephone, or a personal digital assistant.

14. The system of claim 12, wherein the communication unit is configured to wirelessly transmit data corresponding to the analyte level to the remote location.

15. The system of claim 12, wherein the communication unit is configured to receive a flow instruction command to control delivery of the medication.

16. The system of claim 2, wherein the connection port is located on one of a top surface or an end of the first modular component.

17. The system of claim 2, wherein the first modular component comprises a low profile configuration and the third modular component comprises a profile so as to maintain the low profile configuration of the first modular component when the third modular component is connected to the connection port of the first modular component.

18. The system of claim 17, wherein the second modular component comprises a profile so as to maintain the low profile configuration of the first modular component when the second modular component is connected to the connection port of the first modular component.

19. The system of claim 2, wherein the connection port comprises a receptacle configured for receiving a corresponding mating portion of the second modular component and a corresponding mating portion of the third modular component, wherein the two corresponding mating portions have similar configurations.

20. The system of claim 2, wherein the processing unit is within a housing of the first modular component, and wherein the first modular component includes an electronic pump controlled by the processing unit, wherein the electronic pump is also within the housing of the first modular component.
