Abstract

A method is provided for controlling change access to a display menu of an ambulatory liquid infusion pump. A programmed menu of the infusion pump may be displayed and a menu lock flag may be monitored. Changes to at least one active item of the programmed menu may be disabled if the menu lock flag is activated.

Claims

1. A method of controlling change access to a display menu of an ambulatory liquid infusion pump, the method comprising:

displaying a programmed menu of the infusion pump,

monitoring a menu lock flag, and

disabling changes to at least one active item of the programmed menu if the menu lock flag is activated.

2. The method of claim 1 wherein disabling changes comprises disabling changes to all active items of the programmed menu.

3. The method of claim 1 further comprising displaying a warning message upon detection of attempted changes to the at least one active item of the programmed menu if the menu lock flag is activated.

4. The method of claim 1 further comprising enabling changes to the at least one active item of the programmed menu if the menu lock flag is deactivated.

5. The method of claim 1 wherein enabling changes comprises enabling changes to all of the active items of the programmed menu.

6. The method of claim 1 wherein the method is carried out on the ambulatory liquid infusion pump,

and wherein displaying comprises displaying the programmed menu on a display device of the ambulatory liquid infusion pump.

7. The method of claim 1 wherein the method is carried out on an electronic device that is separate and remote from the ambulatory liquid infusion pump,

and wherein displaying comprises displaying the programmed menu on a display device of the electronic device.

8. The method of claim 1 wherein a first version of application software containing the menu is available to users of the ambulatory liquid infusion pump and a second version of the application software containing the menu is available only to health care professionals,

and wherein the menu lock flag is activated in the first version of application software and is deactivated in the second version of the application software.

9. The method of claim 1 wherein a first version of application software containing the menu is available to users of the ambulatory liquid infusion pump and a second version of the application software containing the menu is available only to health care professionals,

and wherein the menu lock flag is activated in the first version of application software,

and wherein the second version of the application software does not include the menu lock flag.

10. A method of extending a pre-programmed lifetime of an ambulatory liquid infusion pump, the method comprising:

monitoring a pre-programmed lifetime timer resident in the liquid infusion pump,

allowing the liquid infusion pump to continue operating after the lifetime timer expires, and

disabling operation of the liquid infusion pump if a liquid infusion pump operating error is detected after the lifetime timer expires.

11. The method of claim 10 further comprising displaying a message on a display device of the liquid infusion pump when the lifetime timer expires.

12. The method of claim 11 wherein the message identifies expiration of the lifetime of the liquid infusion pump.

13. The method of claim 10 further comprising activating at least one of an audible indicator and a vibratory device when the lifetime timer expires.

14. A method of storing information relating to operation of a liquid infusion pump, the method comprising:

periodically storing in a storage location of a non-volatile memory information relating to delivery by the pump of a commanded liquid amount throughout delivery by the pump of the commanded liquid amount,

transferring the information relating to delivery by the pump of the commanded liquid amount from the storage location of the non-volatile memory to a pump history database when delivery by the pump of the commanded liquid amount is complete, and

automatically transferring any information relating to delivery by the pump of a commanded liquid amount that is accumulated in the storage location of the non-volatile memory to the pump history database upon power up of the liquid infusion pump.

15. The method of claim 14 wherein the information relating to delivery by the pump of a commanded liquid amount includes any one or more of a delivered liquid quantity, a percentage of a delivered liquid quantity relative to 100%, one or more associated liquid delivery limits, a liquid delivery type, whether the delivered liquid was locally or remotely commanded, and the time and date of liquid delivery.

16. The method of claim 15 wherein the one or more liquid delivery limits includes one or more of a maximum liquid amount, a minimum liquid amount, a maximum delivery duration and a minimum delivery duration.

17. The method of claim 15 wherein the liquid delivery type is at least one of a basal rate, a temporary basal rate a standard bolus, an extended bolus, a multi-wave bolus and a quick bolus.

18. The method of claim 14 further comprising clearing the non-volatile memory after automatically transferring information from the non-volatile memory to the pump history database.

19. The method of claim 14 wherein the commanded liquid amount is one of a locally commanded liquid amount and a remotely commanded liquid amount.

20. The method of claim 14 wherein periodically storing information relating to delivery by the pump of a commanded liquid amount throughout delivery by the pump of the commanded liquid amount comprises storing information periodically in time.

21. The method of claim 14 wherein periodically storing information relating to delivery by the pump of a commanded liquid amount throughout delivery by the pump of the commanded liquid amount comprises storing the information after each delivery of by the pump of an incremental amount of the commanded liquid amount.
