Abstract

An infusion system to administer a fluid includes an infusion pump with a pump processor, a pump memory to store a plurality of configurable alarms and a pump radio to enable bi-directional communication. The infusion system further includes a controller that has a controller processor, a controller memory, a controller radio to transmit and receive communication from the pump radio. The controller further has a graphical user interface shown on a display along with controls to manipulate the graphical user interface. Furthermore, the bi-directional communication between the infusion pump and the controller establish an infusion pump relative proximity between the infusion pump and the controller such that when the infusion pump relative proximity exceeds a pump threshold distance at least one of the plurality of configurable alarm conditions of the infusion pump is modified.

Claims

1. An infusion system to administer a fluid, the infusion system comprising:

an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication, the pump memory storing a plurality of configurable alarm conditions;

and a controller having a controller processor, a controller memory, a controller radio to transmit and receive communication from the pump radio, the controller further having a graphical user interface shown on a display, and controls to manipulate the graphical user interface, the bi-directional communication between the infusion pump and the controller establishing an infusion pump relative proximity between the infusion pump and the controller such that when the infusion pump relative proximity exceeds a pump threshold distance at least one of the plurality of configurable alarm conditions of the infusion pump is deactivated.

2. An infusion system as described in claim 1, wherein the modification of the at least one of the plurality of configurable alarm conditions is automatic when the relative proximity exceeds the threshold distance.

3. An infusion system as described in claim 1, wherein user interaction with the controller is required to confirm modification of the at least one of the plurality of configurable alarm conditions.

4. An infusion system as described in claim 1, wherein user interaction with the infusion pump is required to confirm modification of the at least one of the plurality of configurable alarm conditions.

5. An infusion system as described in claim 2, wherein the at least one plurality of configurable alarm conditions is a non-delivery alarm.

6. An infusion system as described in claim 1, wherein when the relative proximity no longer exceeds the threshold distance the at least one of the plurality of configurable alarm conditions of the infusion pump is reactivated.

7. An infusion system as described in claim 6, wherein the reactivation of the at least one of the plurality of configurable alarm conditions of the infusion pump is automatic.

8. An infusion system as described in claim 1, further comprising:

a sensor assembly having a sensor placed within an analyte, the sensor assembly further having a sensor radio to enable bi-directional communication with the controller and provide continuous monitoring of the analyte,

the analyte being within subcutaneous tissue of a user, the sensor radio remaining outside of the user.

9. An infusion system as described in claim 8, wherein the bi-directional communication between the sensor assembly and the controller establish a sensor relative proximity defined by a distance between the controller and the sensor assembly.

10. An infusion system as described in claim 9, wherein value fluid delivery from the infusion pump is suspended while continuous monitoring of the analyte continues, when the infusion pump relative proximity exceeds the pump threshold distance.

11. An infusion system as described in claim 10, wherein data from the continuing continuous monitoring is stored in the controller memory.

12. An infusion system as described in claim 11, wherein the controller processor executes stored program instructions to enable the continuous monitoring data stored in the controller memory to be shown on the display.

13. An infusion system to administer a fluid, the infusion system comprising:

an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication, the pump memory storing a plurality of configurable alarm conditions;

a sensor assembly having a sensor to be placed within an analyte, the sensor assembly further having a sensor radio to enable bi-directional communication with the controller and provide continuous monitoring of the analyte; and

a controller having a controller processor, a controller memory, a controller radio to transmit and receive communication from the pump radio, the controller further having a graphical user interface shown on a display, and controls to manipulate the graphical user interface, the bi-directional communication between the infusion pump and the controller establishing an infusion pump relative proximity between the infusion pump and the controller such that when the infusion pump relative proximity exceeds a pump threshold distance a prompt is delivered to request user confirmation to deactivate at least one of the plurality of configurable alarm conditions of the infusion pump.

14. An infusion system as described in claim 13, wherein the pump threshold distance is defined using the user interface of the controller.

15. An infusion system as described in claim 13, wherein deactivation of the at least one of the plurality of configurable alarm conditions is completed upon user confirmation.

16. An infusion system as described in claim 15, wherein continuous monitoring of the analyte continues after the at least one of the plurality of configurable alarm conditions is deactivated.
