1. A medical infusion pump system, comprising:

  • a portable pump housing that receives insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user;

    a controller that communicates with the pump drive system to dispense the insulin from the portable pump housing, the controller being configured to calculate an insulin load of the user representing an estimated amount of insulin delivered to the user'"'"'s body which has not yet acted; and

    a monitoring device that communicates the glucose information to the controller, and a computer-readable memory device coupled to the controller that stores the glucose information received from the monitoring device and time values associated with the glucose information, wherein the monitoring device comprises a portable housing wearable on the user'"'"'s skin, a sensor shaft that penetrates into the user'"'"'s skin, and a wireless communication device to transmit the glucose information to a wireless communication device of the controller,wherein the controller receives glucose information indicative of a detected blood glucose level of the user, wherein the controller outputs an alarm when the glucose information indicates that the detected blood glucose level reaches beyond a glucose alarm limit parameter, wherein the controller repeats the alarm at the end of a selected time interval and is configured to adjust the duration of the selected time interval based on the calculated insulin load of the user representing an estimated amount of insulin delivered to the user'"'"'s body which has not yet acted, wherein the glucose alarm limit parameter is dynamically changed over time by the controller as the insulin load of the user increases or decreases.
