Abstract

An ambulatory infusion pump can include a maximum bolus override procedure. When a bolus amount greater than a maximum bolus amount is requested, the pump can provide an alert indicating that the amount requested exceeds the maximum bolus amount. If the user confirms the request in response to the alert, the bolus amount can be delivered to the user. The amount delivered in response to the confirmation can be a first portion of the bolus amount. A reminder can then be provided that a second portion of the bolus amount that is a remaining portion of the requested bolus amount was also requested. If a second confirmation is received in response to the alert, the second portion of the bolus amount can also delivered to the user.

Claims

1. An ambulatory infusion pump, comprising:

a delivery mechanism adapted to facilitate delivery of insulin to a user;

a user interface adapted to display operating parameters of the delivery mechanism and to receive input data from a user;

a memory adapted to store a maximum bolus limit defining a maximum bolus amount a user is allowed to enter into the user interface for delivery by the delivery mechanism; and

a processor operably connected to the delivery mechanism, user interface and memory, the processor adapted to execute a maximum bolus override procedure when input data from the user requests a bolus amount greater than the maximum bolus amount, the maximum bolus override procedure comprising;

providing an alert, indicating that the bolus amount in the request exceeds the maximum bolus limit;

receiving a confirmation of the request in response to the alert; and

causing the delivery mechanism to deliver the bolus amount to the user in response to the confirmation.

2. The ambulatory infusion pump of claim 1, wherein causing the delivery mechanism to deliver the bolus amount in response to the confirmation comprises delivering a first portion of the bolus amount and the maximum bolus override procedure the processor is adapted to execute further comprises:

after the first portion of the bolus amount is delivered to the user, providing a reminder that a second portion of the bolus amount comprising a remainder of the bolus amount was requested;

receiving a second confirmation to deliver the second portion of the bolus amount; and

causing the delivery mechanism to deliver the second portion of the bolus amount to the user in response to the second confirmation.

3. The ambulatory infusion pump of claim 2, wherein the first portion of the bolus amount is equal to the maximum bolus amount.

4. The ambulatory infusion pump of claim 2, wherein the first portion of the bolus amount is a predetermined percentage of the bolus amount.

5. The ambulatory infusion pump of claim 1, wherein the user interface is adapted to enable the user to set the maximum bolus limit.

6. The ambulatory infusion pump of claim 5, wherein the memory stores a maximum limit for the maximum bolus amount, and the processor is further adapted to inhibit the user from setting the maximum bolus amount above the maximum limit.

7. The ambulatory infusion pump of claim 2, wherein the first portion of the bolus amount is not delivered if the confirmation is not received within a predetermined period of time.

8. The ambulatory infusion pump of claim 2, wherein the first portion of the bolus is automatically delivered if the confirmation is not received within a predetermined period of time.

9. The ambulatory infusion pump of claim 2, wherein the second portion of the bolus is not delivered if the second confirmation is not received within a predetermined period of time.

10. The ambulatory infusion pump of claim 1, wherein the alert is displayed on the user interface.

11. The ambulatory infusion pump of claim 10, wherein the alert further includes at least one of an audio and a tactile alert.

12. The ambulatory infusion pump of claim 1, wherein the user interface is a graphical user interface.

13. An ambulatory infusion pump, comprising:

a delivery mechanism adapted to facilitate delivery of insulin to a user;

a user interface adapted to display operating parameters of the delivery mechanism and to receive input data from a user;

a memory adapted to store a maximum bolus limit defining a maximum bolus amount a user is allowed to enter into the user interface for delivery by the delivery mechanism; and

a processor operably connected to the delivery mechanism, user interface and memory, the processor adapted to execute a maximum bolus override procedure when input data from the user requests a bolus amount greater than the maximum bolus amount, the maximum bolus override procedure comprising;

providing an alert on the user interface indicating that the bolus amount in the request exceeds the maximum bolus limit;

receiving a confirmation of the request in response to the alert through the user interface;

causing the delivery mechanism to deliver a first portion of the bolus amount to the user in response to the confirmation;

after the first portion of the bolus amount is delivered to the user, providing a reminder on the user interface that a second portion of the bolus amount comprising a remainder of the bolus amount was requested;

receiving a second confirmation through the user interface to deliver the second portion of the bolus amount; and

causing the delivery mechanism to deliver the second portion of the bolus amount to the user in response to the second confirmation.

14. The ambulatory infusion pump of claim 13, wherein the first portion of the bolus amount is equal to the maximum bolus amount.

15. The ambulatory infusion pump of claim 13, wherein the first portion of the bolus amount is a predetermined percentage of the bolus amount.

16. The ambulatory infusion pump of claim 13, wherein the graphical user interlace is adapted to permit the user to set the maximum bolus limit.

17. The ambulatory infusion pump of claim 16, wherein the memory stores a maximum limit for the maximum bolus amount, and the processor is further adapted to inhibit the user from setting the maximum bolus amount above the maximum limit.

18. The ambulatory infusion pump of claim 13, wherein the alert and the reminder each further include at least one of an audio and a tactile alert.

19. The ambulatory infusion pump of claim 13, wherein the user interface is a graphical user interlace.

20. A method of overriding a maximum bolus limit in an ambulatory infusion pump, comprising:

storing a maximum bolus limit defining a maximum bolus amount a user is allowed to enter into a user interface of the infusion pump for delivery by a delivery mechanism of the ambulatory infusion pump;

receiving input data from the user interlace requesting a bolus amount greater than the maximum bolus amount;

providing an alert indicating that, the bolus amount in the request exceeds the maximum bolus limit;

receiving a confirmation of the request in response to the alert; and

causing the delivery mechanism to deliver the bolus amount to the user in response to the confirmation.

21. The method of claim 20, wherein causing the delivery mechanism to deliver the bolus amount in response to the confirmation comprises delivering a first portion of the bolus amount, the method further comprising:

after the first portion of the bolus amount is delivered to the user, providing a reminder that a second portion of the bolus amount comprising a remainder of the bolus amount was requested;

receiving a second confirmation to deliver the second portion of the bolus amount; and

causing the delivery mechanism to deliver the second portion of the bolus amount to the user in response to the second confirmation.

22. The method of claim 20, wherein storing a maximum bolus limit defining a maximum bolus amount includes receiving input data through the user interface defining the maximum bolus limit.

23. The method of claim 20, wherein storing a maximum bolus limit includes storing a maximum limit above which the maximum bolus limit cannot be set.
