Abstract: The exemplary embodiments may provide a drug delivery device that receives glucose level values for a user (e.g., a diabetic patient) and based on the glucose level values, determines when the user has consumed a meal. In some embodiments, the drug delivery device may calculate an appropriate bolus dose and automatically deliver the drug bolus to the user. In some embodiments, instead of detecting the meal, the user may announce the meal, such as by activating an element on the drug delivery device or on a management device for the drug delivery device. Responsive to the meal announcement, the drug delivery device may calculate the drug bolus dose and deliver the drug bolus. In conjunction with the delivery of the drug bolus, the drug delivery device may relax one or more safety constraints for a relaxation period following the drug bolus delivery so that additional basal drug may be delivered, if needed, under relaxed constraints.
