Abstract

An ambulatory medical device is disclosed. The device comprises a device controller, an alert controller, and an indicator. The device controller may be configured to control the operation of the ambulatory medical device. The alert controller may be configured to: determine a first alerting interval, the first alerting interval defining an earliest point in time and a latest point in time for an alert generation due to a first alerting cause; determine in the first alerting interval an alerting point in time based on an alerting criterion; and generate an alert trigger at the alerting point in time. The indicator may be configured to generate an alert upon generation of the alert trigger. The alerting criterion may be used to generate an alert within the alerting interval at a time especially suited and/or convenient for the device user.

Claims

1. An ambulatory medical device, comprising:

a) a device controller, the device controller configured to control operation of the ambulatory medical device;

b) an alert controller, the alert controller configured to;

determine a first alerting interval, the first alerting interval defining an earliest point in time and a latest point in time for an alert generation due to a first alerting cause,

determine in the first alerting interval an alerting point in time based on an alerting criterion,

generate an alert trigger at the alerting point in time; and

c) an indicator, the indicator configured to generate an alert upon generation of the alert trigger.

2. The ambulatory medical device of claim 1, wherein the alert controller is further configured to:

determine a second alerting interval, the second alerting interval defining an earliest point in time and a latest point in time for an alert generation due to a second alerting cause, and

detect an overlap interval of the first alerting interval and the second alerting interval,

wherein the alerting criterion is provided such that the alert is generated in the overlap interval and the alert is a common alert for the first alerting cause and the second alerting cause and the indicator is configured to indicate the first alerting cause and the second alerting cause.

3. The ambulatory medical device of claim 2, wherein the alerting criterion is defined such that the alert trigger is generated at the end of either the first alerting interval or the second alerting interval.

4. The ambulatory medical device of claim 1, wherein the first alerting cause is approaching exploitation of a first disposable, and the first alerting interval reflecting an earliest and a latest grade of exploitation for replacing the first disposable.

5. The ambulatory medical device of claim 4, wherein the first disposable is an energy storage, a drug reservoir, an infusion line, an infusion cannula, a valve, a sealing, or a glucose measurement probe.

6. The ambulatory medical device of claim 2, wherein the second alerting cause is approaching exploitation of a second disposable and the second alerting interval reflecting an earliest and a latest grade of exploitation for replacing the second disposable.

7. The ambulatory medical device of claim 1, wherein the alerting criterion comprises a time-dependent user acceptance of the generated alert.

8. The ambulatory medical device of claim 6, further comprising a user acceptance storage, the user acceptance storage configured to store a user acceptance profile, the user acceptance profile is indicative of user acceptance of the generated alert as a function of time.

9. The ambulatory medical device of claim 8, wherein the device controller is configured to store a history and the alert controller is configured to modify the user acceptance profile based on data stored in the history.

10. The ambulatory medical device of claim 7, further comprising a user interface and a data interface, wherein the alert controller is configured to temporarily modify the time-dependent user acceptance of the generated alert in accordance with data provided via the user interface and the data interface.

11. The ambulatory medical device of claim 10, wherein the user interface and the data interface are configured to receive data defining a modification time interval, and the alert controller is configured to modify the time-dependent user acceptance of the generated alert for the modification time interval.

12. The ambulatory medical device of claim 7, wherein the alert controller is configured to modify the time-dependent user acceptance of the generated alert on at least one of an occurrence of a user interaction with the ambulatory medical device, an occurrence of an error state, or an resolving of an error state.

13. The ambulatory medical device of claim 7, wherein the alert controller is configured to detect an overlap interval of high user acceptance for the generated alert and an alerting interval, wherein the alerting criterion is provided such that the alert trigger is generated in the overlap interval.

14. The ambulatory medical device of claim 13, wherein the alerting criterion is defined such that the alert trigger is generated when the overlap interval of high user acceptance for the generated alert and the alerting interval ends.

15. The ambulatory medical device of claim 1, further comprising a prediction unit, the prediction unit configured to predict at least one of an alerting interval or the alerting point in time.
