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 system, comprising:

a pump mechanism configured to facilitate delivery of a medicament to a user;

a user interface configured to display operating parameters of the pump mechanism and to receive input from the user;

a memory adapted to store a maximum bolus amount limit defining a maximum amount of the medicament the user can operate the pump mechanism to deliver in a single bolus; and

a processor configured to execute a procedure when the user manually enters a request through the user interface for delivery of a single bolus of medicament that exceeds the maximum bolus amount limit, the procedure comprising;

providing a warning on the user interface notifying the user that the user-requested, single bolus of medicament exceeds the maximum bolus amount limit;

receiving a confirmation of the user-requested, single bolus of medicament in response to the alert; and

instructing delivery via the pump mechanism of the maximum bolus amount limit in response to the receipt of the confirmation.

2. The ambulatory infusion pump system of claim 1, further comprising notifying the user that the maximum bolus amount limit was delivered rather than the user-requested single bolus of medicament exceeding the maximum bolus amount limit.

3. The ambulatory infusion pump system of claim 1, wherein the user interface is configured to enable the user to set the maximum bolus amount limit.

4. The ambulatory infusion pump system of claim 1, wherein the memory stores a maximum limit for the maximum bolus amount limit, and the processor is further adapted to inhibit the user from setting the maximum bolus amount limit above the maximum limit.

5. The ambulatory infusion pump system of claim 1, wherein the request for delivery of a single bolus of medicament that exceeds the maximum bolus amount limit includes the amount being manually entered by the user in units of insulin.

6. The ambulatory infusion pump system of claim 1, wherein the procedure further comprises not delivering a remainder of the user-requested, single bolus of medicament greater than the maximum bolus amount limit.

7. The ambulatory infusion pump system of claim 1, wherein the maximum bolus amount limit is defined in units of insulin.

8. An ambulatory infusion pump system, comprising:

a pump mechanism configured to facilitate delivery of a medicament to a user;

a user interface configured to display operating parameters of the pump mechanism and to receive input from the user;

a memory adapted to store a max bolus setting amount defining a maximum amount of the medicament the user can operate the pump mechanism to deliver in a single bolus; and

a processor configured to execute a procedure when the user manually enters a request through the user interface for delivery of a single bolus of medicament that exceeds the max bolus setting amount, the procedure comprising;

provide a warning on the user interface indicating that the max bolus setting amount has been exceeded by the user-requested single bolus of medicament;

receive a confirmation of the user-requested single bolus of medicament in response to the warning;

automatically reduce the user-requested single bolus of medicament to the max bolus setting amount; and

instruct delivery via the pump mechanism of the max bolus setting amount in response to receipt of the confirmation.

9. The ambulatory infusion pump system of claim 8, further comprising notifying the user that the max bolus setting amount was delivered rather than the user-requested single bolus of medicament.

10. The ambulatory infusion pump system of claim 8, wherein the user interface is configured to enable the user to set the max bolus setting amount.

11. The ambulatory infusion pump system of claim 8, wherein the memory stores a maximum limit for the max bolus setting amount, and the processor is further adapted to inhibit the user from setting the max bolus setting amount above the maximum limit.

12. The ambulatory infusion pump system of claim 8, wherein the request for delivery of a single bolus of medicament that exceeds the max bolus setting amount includes the amount being manually entered by the user in units of insulin.

13. An ambulatory infusion pump system, comprising:

an ambulatory infusion pump including a pump mechanism configured to facilitate delivery of a medicament to a user;

a remote commander configured to transmit commands to the ambulatory infusion pump for operation of the ambulatory infusion pump, the remote commander including a user interface, a memory adapted to store a maximum bolus amount limit defining a maximum bolus amount of the medicament the user can cause the ambulatory infusion pump to deliver in a single bolus and a processor configured to execute a procedure when the user manually enters a request through the user interface for delivery of a single bolus of medicament that exceeds the maximum bolus amount limit, the procedure comprising;

provide a warning on the user interface indicating that the user-requested, single bolus of medicament exceeds the maximum bolus amount limit;

receive a confirmation of the user-requested, single bolus of medicament in response to the warning;

automatically reduce the user-requested, single bolus of medicament to the maximum bolus amount limit; and

instruct the ambulatory infusion pump to proceed with delivering the maximum bolus amount limit.

14. The ambulatory infusion pump system of claim 13, further comprising notifying the user that the maximum bolus amount limit was delivered rather than the user-requested, single bolus of medicament.

15. The ambulatory infusion pump system of claim 13, wherein the user interface is configured to enable the user to set the maximum bolus amount limit.

16. The ambulatory infusion pump system of claim 13, wherein the memory stores a maximum limit for the maximum bolus amount limit, and the processor is further adapted to inhibit the user from setting the maximum bolus amount limit above the maximum limit.

17. The ambulatory infusion pump system of claim 13, wherein the request for delivery of a single bolus of medicament that exceeds the maximum bolus amount limit includes the amount being manually entered by the user in units of insulin.

18. The ambulatory infusion pump system of claim 13, wherein the remote commander is a cell phone.

19. The ambulatory infusion pump system of claim 13, wherein the procedure further comprises not delivering a remainder of the user-requested, single bolus of medicament greater than the maximum bolus amount limit.
