Control unit for infusion pump units, including a controlled intervention unit
First Claim
1. A system for an electronically controlled pump unit, comprising:
- a preset infusion schedule configured to control a pump unit to infuse insulin into a diabetic'"'"'s body in a substantially continuous manner;
an intervention unit configured to continuously evaluate a glucose indicative input from a glucose sensor for detecting an actual or expected hypoglycaemia and to execute, in response to an actual or expected hypoglycaemia, a temporary hypoglycaemia intervention, the hypoglycaemia intervention including, for an intervention time interval, overriding the preset infusion schedule by temporarily suspending insulin infusion or temporarily reducing insulin infusion below the preset infusion schedule;
a control unit configured to operatively coupled to a fasting period sensor and further configured to generate a control signal according to a fasting period measure provided by the fasting period sensor; and
wherein the control unit is configured to enable execution of the hypoglycaemia intervention upon the fasting period measure indicating that a diabetic associated with the control unit has fallen asleep, has gone to bed, or can be expected to fall asleep or go to bed soon.

Abstract
A control unit for an electronically controlled pump unit controls the pump unit to infuse insulin into a diabetic'"'"'s body in a substantially continuous way according to a preset infusion schedule as a function of time. The control unit includes an intervention unit that continuously evaluates a blood-glucose indicative input for detecting an actual or expected hypoglycaemia and executes, in response to an actual or expected hypoglycaemia, a temporary hypoglycaemia intervention. The intervention includes, for an intervention time interval, overriding the preset infusion schedule by temporarily suspending insulin infusion or temporarily reducing insulin infusion below the preset infusion schedule. The intervention unit adapts its way of operation with respect to executing the hypoglycaemia intervention in accordance with a control signal that is separate from the blood-glucose indicative input. The control unit automatically generates the control signal as a function of time and/or based on sensor input.
