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

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, wherein the controller is configured to, in response to receiving input indicative of a user-prompted bolus dosage, temporarily interrupt the closed-loop delivery mode by dispensing from the infusion pump system the user-prompted bolus dosage, wherein a calculated dosage amount of the user-prompted bolus dosage is calculated by the infusion pump system based upon both user input and an amount of insulin dispensed during the closed-loop delivery mode over a time period prior to the user-prompted bolus dosage. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of operating a portable infusion pump system, comprising:
-
while operating an infusion pump system to dispense insulin according to a closed-loop delivery mode in which insulin is dispensed in response to feedback information of a user'"'"'s blood glucose characteristic, detecting a trigger event to initiate a user-selected manual bolus dosage; temporarily interrupting the closed-loop delivery mode by dispensing from the infusion pump system the user-selected manual bolus dosage; and automatically returning to the closed-loop delivery mode after dispensation of the user-selected manual bolus dosage. - View Dependent Claims (19)

20. 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 by dispensing from the infusion pump system a user-selected manual bolus dosage and is configured to restart the closed-loop delivery mode after dispensation of the user-selected manual bolus dosage.

21. A method of operating a portable insulin infusion pump system, comprising:
-
while operating an infusion pump system to dispense insulin according to a closed-loop delivery mode, detecting a trigger event to initiate a user-selected manual bolus dosage; determining, at the infusion pump system, that the bolus dosage is permissible based on an amount of the bolus dosage and an amount of insulin dispensed during the closed-loop delivery mode over a time period immediately prior to the trigger event; and initiating delivery of the permissible bolus dosage. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
