Medical infusion pump capable of learning bolus time patterns and providing bolus alerts
First Claim
1. A medical infusion pump, comprising:
- an infusion pump processor in the medical infusion pump;
an actuator in the medical infusion pump coupled to the infusion pump processor suitable for delivering medicament doses to a user;
a storage coupled to the infusion pump processor, the storage further comprising more than one time interval groups, each of the more than one time interval groups being capable of storing one or more bolus time intervals;
an input device coupled to the infusion pump processor suitable to allow the user to cause a bolus to be delivered;
an alert mechanism coupled to the infusion pump processor suitable to warn the user; and
a timer coupled to the infusion pump processor capable of maintaining time information;
wherein the processor determines, using the user'"'"'s history of boluses delivered by the medical infusion pump in each of the more than one time interval groups, the one or more bolus time intervals during which a bolus is usually taken by the user in the each of the more than one time interval groups, and, activating the alerting mechanism at one or more calculated alert times associated with an active bolus time interval in the one or more bolus time intervals, if a bolus has not been taken yet in the active bolus time interval.

Abstract
An apparatus and method are disclosed for improving a medical infusion pump. Users of medical infusion pumps, such as insulin pumps, require a bolus of a medication at predicable times of the day, such as at or near mealtimes for insulin pumps. The disclosed medical infusion pump determines bolus time intervals during which boluses are usually taken, and, alerts the user at one or more calculated alert times during an active bolus time interval when a bolus has not yet been delivered during the active bolus time interval. Advantageously, a different set of bolus time intervals are determined by day of week, to accommodate, for example, different bolus patterns during weekends versus weekdays.

15. A method of alerting a user of a medical infusion pump, comprising the steps of:
-
storing, in the medical infusion pump, time information at which boluses are taken by the user;
determining, by the medical infusion pump, one or more bolus time intervals during which a bolus is usually taken by the user, using the time information; and
alerting the user when a current time equals one or more calculated alert times associated with an active bolus time interval until a bolus is taken during the active bolus time interval. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of alerting a user of a medical infusion pump, comprising the steps of:
-
learning, by the medical infusion pump, one or more bolus time intervals during which a user of the medical infusion pump normally takes a bolus; and
alerting the user at one or more calculated alert times associated with an active bolus time interval in the one or more bolus time intervals if a bolus has not yet been taken prior to the calculated alert time. - View Dependent Claims (32, 33, 34, 35, 36)
