Abstract

An apparatus for inserting an infusion device for supplying a fluid to a body of a user, and a sensor for monitoring a body characteristic of the user, the apparatus including a bridge including a rigid body and comprising an infusion device end and a sensor end, the bridge further including an infusion device introduction needle attached to the infusion device end, a sensor introduction needle, the sensor introduction needle attached to the sensor end, an infusion device, operatively coupled to the infusion device introduction needle, for infusing a fluid to an infusion site, and a sensor introduction needle operatively coupled to an electrochemical sensor having a sensor electrode for determining at least one body characteristic of the patient at a sensor placement site, an infusion device release for releasing the infusion device from the infusion device introduction needle, and a sensor release for releasing the sensor from the sensor introduction needle.

First claim

What is claimed is:

1. An apparatus for inserting both an infusion device for supplying a fluid to a body of a user, and a sensor comprising a sensor electrode for monitoring a body characteristic of the user at an infusion site, the apparatus comprising:
a bridge comprising an infusion device end and a sensor end;
an infusion device introduction needle attached to the infusion device end;
a sensor introduction needle, the sensor introduction needle attached to the sensor end;
an infusion device, operatively coupled to the infusion device introduction needle;
a sensor operatively coupled to the sensor introduction needle;
an infusion device release for releasing the infusion device from the infusion device introduction needle; and
a sensor release for releasing the sensor from the sensor introduction needle,

wherein the infusion device and the sensor are disposed on the bridge wherein they operatively engage and disengage from the bridge.

2. The apparatus of claim 1 , wherein the infusion device introduction needle and the sensor introduction needle are coupled to the bridge in an orientation such that when the infusion device introduction needle and the sensor introduction needle are inserted into a patient, the infusion site and the sensor electrode are separated by at least 7 millimeters of tissue.

3. The apparatus of claim 1 , wherein the infusion device introduction needle and the sensor introduction needle remain attached to the bridge.

4. The apparatus of claim 1 , wherein the infusion device introduction needle and the sensor introduction needle are metal needles.

5. The apparatus of claim 1 , further comprising an infusion set tubing adapted to connect to the infusion device.

6. The apparatus of claim 5 , further comprising an infusion pump adapted to connect to the infusion set tubing.

7. The apparatus of claim 1 , wherein the apparatus is in a modular configuration that allows the infusion device and the sensor to be replaced independently of other components of the apparatus.

8. A method for insertion of an infusion device and an electrochemical sensor comprising a sensor electrode that monitors a body characteristic of a user, the method comprising using an insertion apparatus comprising:
a bridge;
an infusion device introduction needle attached to the bridge, wherein the infusion device introduction needle is removably coupled to an infusion device that supplies a fluid to the user at an infusion site;
a sensor introduction needle attached to and extending from the bridge and removably coupled to an electrochemical sensor;
an infusion device release for releasing the infusion device from the infusion device introduction needle; and
a sensor release for releasing the electrochemical sensor from the sensor introduction needle,

wherein the infusion device and the sensor are disposed on the bridge wherein they operatively engage and disengage from the bridge.

9. The method of claim 8 , wherein the infusion device introduction needle and the sensor introduction needle are coupled to the bridge in an orientation such that when the infusion device introduction needle and the sensor introduction needle are inserted into a patient, the infusion site and the sensor electrode are separated by at least 7 millimeters of tissue.

10. The method of claim 8 , wherein the infusion device introduction needle and the sensor introduction needle remain attached to the bridge.

11. The method of claim 8 , wherein the infusion device introduction needle and the sensor introduction needle are metal needles.

12. The method of claim 8 , further comprising an infusion set tubing adapted to connect to the infusion device.

13. The method of claim 12 , further comprising an infusion pump adapted to connect to the infusion set tubing.

14. The method of claim 8 , wherein the apparatus is in a modular configuration that allows the infusion device and the sensor to be replaced independently of other components of the apparatus.

15. An apparatus for inserting both an infusion device for supplying a fluid to a body of a user at an infusion site, and a sensor for monitoring a body characteristic of the user, the apparatus comprising:
a bridge comprising an infusion device end and a sensor end;
an infusion device introduction needle attached to the infusion device end;
a sensor introduction needle, the sensor introduction needle attached to the sensor end;
an infusion device, operatively coupled to the infusion device introduction needle;
a sensor having a sensor electrode operatively coupled to the sensor introduction needle;
an infusion device release for releasing the infusion device from the infusion device introduction needle; and
a sensor release for releasing the sensor from the sensor introduction needle,

wherein the infusion device and the sensor are disposed on the bridge wherein they operatively engage and disengage from the bridge, and
wherein the infusion device introduction needle and sensor introduction needle remain attached to the bridge.

16. The apparatus of claim 15 , wherein the infusion device introduction needle and the sensor introduction needle are coupled to the bridge in an orientation such that when the infusion device introduction needle and the sensor introduction needle are inserted into a patient, the infusion site and the sensor electrode are separated by at least 7 millimeters of tissue.

17. The apparatus of claim 15 , wherein the infusion device introduction needle and the sensor introduction needle are metal needles.

18. The apparatus of claim 15 , further comprising an infusion set tubing adapted to connect to the infusion device.

19. The apparatus of claim 18 , further comprising an infusion pump adapted to connect to the infusion set tubing.

20. The apparatus of claim 15 , wherein the apparatus is in a modular configuration that allows the infusion device and the sensor to be replaced independently of other components of the apparatus.
