Abstract

A user-wearable infusion pump system includes an inductively or otherwise wirelessly chargeable battery and at least one button. Activation of the at least one button when not in the presence of an inductive charging signal can enable and/or initiate a first function or operation and activation of the at least one button in the presence of an inductive charging signal can enable and/or initiate a different, second function or operation. Such functionality can also be enabled in the presence of other types of electromagnetic signals.

Claims

1. A user-wearable infusion pump, comprising:

a reservoir configured to contain a medicament;

a drive mechanism configured to facilitate delivery of the medicament to a user;

a rechargeable battery configured to be charged wirelessly;

an input button; and

a processor functionally linked to the input button and configured to receive input for control of functions of the user-wearable infusion pump in response to input received via the input button, wherein the processor is configured to;

detect a presence of a wireless changing signal;

receive a first input via the input button to cause the user-wearable infusion pump to execute a first function in response to the first input received via the first input button in an absence of the wireless charging signal, the first function being initiating a medicament delivery operation with the user-wearable infusion pump; and

receive a second input via the input button, the second input being the same as the first input, in the presence of the wireless charging signal to cause the user-wearable infusion pump to execute a second function different from the first function when the second input the same as the first input is received in the presence of the wireless charging signal, wherein the second function comprises activating a pairing feature of the user-wearable infusion pump for pairing the user-wearable infusion pump with a remote control.

2. The user-wearable infusion pump of claim 1, wherein the pump includes only a single input button.

3. The user-wearable infusion pump of claim 1, wherein the pump does not include a display screen.

4. The user-wearable infusion pump of claim 3, wherein the processor is further configured to wirelessly communicate pump information to a separate device for display on the separate device.

5. The user-wearable infusion pump of claim 1, further comprising an indicator light.

6. The user-wearable infusion pump of claim 5, wherein the indicator light is functionally linked to the input button such that the indicator light illuminates to indicate that input has been received via the input button.

7. The user-wearable infusion pump of claim 5, wherein the indicator light is functionally linked to the input button such that the indicator light illuminates to indicate when the first function is being executed and when the second function is being executed.

8. The user-wearable infusion pump of claim 7, wherein the indicator light is illuminated differently to indicate when the first function is being executed and when the second function is being executed.

9. The user-wearable infusion pump of claim 1, wherein the wireless charging signal is an inductive charging signal.

10. A user-wearable infusion pump, comprising:

a reservoir configured to contain a medicament;

a drive mechanism configured to facilitate delivery of the medicament to a user;

an input button; and

a processor functionally linked to the input button and configured to receive input for control of functions of the user-wearable infusion pump in response to input received via the input button, wherein the processor is configured to;

detect a presence of a type of externally originating electromagnetic signal;

receive a first input via the input button to cause the user-wearable infusion pump to execute a first function directly in response to the first input received via the first input button in an absence of the type of externally originating electromagnetic signal, the first function being initiating a medicament delivery operation with the user-wearable infusion pump; and

receive a second input via the input button, the second input being the same as the first input when in the presence of the type of externally originating electromagnetic signal,

to cause the user-wearable infusion pump to execute a second function different from the first function when the second input the same as the first input is received because of the presence of the type of externally originating electromagnetic signal, the second function being activating a pairing feature of the user-wearable infusion pump for pairing the user-wearable infusion pump with a remote control.

11. The user-wearable infusion pump of claim 10, wherein the type of externally originating electromagnetic signal is a wireless charging signal transmitted by a wireless charger.

12. The user-wearable infusion pump of claim 11, wherein the wireless charging signal is an inductive charging signal and the wireless charger is an inductive charger.

13. The user-wearable infusion pump of claim 10, wherein the type of externally originating electromagnetic signal is a BLUETOOTH beacon transmitted by the remote control.

14. The user-wearable infusion pump of claim 13, wherein the BLUETOOTH beacon includes a unique identifier and wherein the processor is further configured to match the unique identifier with a known remote control.

15. The user-wearable infusion pump of claim 13, wherein the remote control is selected from the set consisting of a dedicated remote control for the user-wearable pump and a mobile communication device executing a software application configured to communicate with the user-wearable pump.

16. The user-wearable infusion pump of claim 10, wherein the pump includes only a single input button.

17. The user-wearable infusion pump of claim 10, wherein the pump does not include a display screen.

18. The user-wearable infusion pump of claim 17, wherein the processor is further configured to wirelessly communicate pump information to a separate device for display on the separate device.

19. The user-wearable infusion pump of claim 10, further comprising an indicator light.

20. The user-wearable infusion pump of claim 19, wherein the indicator light is functionally linked to the input button such that the indicator light illuminates to indicate that input has been received via the input button.

21. The user-wearable infusion pump of claim 19, wherein the indicator light is functionally linked to the input button such that the indicator light illuminates to indicate when the first function is being executed and when the second function is being executed.

22. The user-wearable infusion pump of claim 21, wherein the indicator light is illuminated differently to indicate when the first function is being executed and when the second function is being executed.
