1. A method of operating a portable insulin infusion pump system, comprising:
- while operating an infusion pump system to automatically dispense insulin according to a closed-loop delivery mode, detecting a trigger event from a user to initiate a user-selected manual bolus dosage;
temporarily interrupting the closed-loop delivery mode;
receiving a user input for the user-selected manual bolus dosage;
calculating, by the infusion pump system, a calculated dosage amount of the user-selected manual bolus dosage based upon both the user input and an amount of insulin dispensed during the closed-loop delivery mode over a time period immediately prior to said interrupting;
dispensing from the infusion pump system the calculated dosage amount;
determining that the user-selected manual bolus dosage is administered; and
automatically returning to the closed-loop delivery mode in response to determining that the user-selected manual bolus dosage is administered.

10. A medical infusion pump system, comprising:
-
a portable pump housing configured to receive medicine for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the medicine through a flow path to the user; and a controller that controls the pump drive system to; dispense the medicine from the portable pump housing according to a closed-loop delivery mode in which the controller autonomously provides insulin dosages to the user in response to feedback information of a user'"'"'s blood glucose level; receive user input to initiate a user-prompted bolus dosage; in response to receiving the user input to initiate the user-prompted bolus dosage, temporarily interrupt the closed-loop delivery mode; receive a user input for the user-prompted bolus dosage; calculate, by the infusion pump system, a calculated dosage amount of the user-prompted bolus dosage based upon both the user input for the user-prompted bolus dosage and an amount of insulin dispensed during the closed-loop delivery mode over a time period immediately prior to said interrupting; dispense from the infusion pump system the user-prompted bolus dosage; determine that the user-selected manual bolus dosage is administered; and automatically return to the closed-loop delivery mode in response to determining that the user-selected manual bolus dosage is administered. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A portable infusion pump system, comprising:
-
a portable pump housing configured to receive medicine for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the medicine through a flow path to the user; control circuitry that controls the pump drive system to dispense the medicine from the portable pump housing according to a closed-loop delivery mode in which insulin is dispensed in response to feedback information of a user'"'"'s blood glucose characteristic; and a user interface in communication with the control circuitry and being configured to receive user input to interrupt said closed-loop delivery mode, wherein the control circuitry is configured to; temporarily interrupt the closed-loop delivery mode in response to the user input to interrupt said closed-loop delivery mode; receive manual bolus dosage information indicative of user input received by the user interface, the manual bolus dosage information indicating a numeric value associated with a manual bolus dosage; calculate a calculated dosage amount for the manual bolus dosage based upon the manual bolus dosage information; dispense from the infusion pump system the manual bolus dosage; determine that the manual bolus dosage is administered; and restart the closed-loop delivery mode in response to determining that the manual bolus dosage is administered.
