1. A method of operating an insulin infusion pump system, comprising:
- activating an occlusion detection system to detect a fluid pressure in a flow path extending from an insulin reservoir in a portable insulin pump apparatus to a user, the portable insulin pump apparatus including a pump drive system to dispense insulin through the flow path to the user;
activating the pump drive system to deliver an incremental dosage of insulin;
in response to a signal from the occlusion detection system indicating a fluid pressure greater than a threshold pressure limit for the incremental dosage of insulin, increasing a counter value stored in a memory device of the portable insulin pump apparatus while foregoing output of an occlusion alarm;
in response to a signal from the occlusion detection system indicating a fluid pressure less than or equal to the threshold pressure limit for each incremental dosage of insulin, resetting the counter value to zero;
adjusting a threshold counter value based on glucose information; and
in response to the counter exceeding the threshold counter value, outputting the occlusion alarm from portable insulin pump apparatus to the user.

Abstract
Some embodiments of a portable infusion pump system can be configured to can be configured to adjust the sensitivity of particular detectors or alert systems based (at least in part) on information received from a monitoring device. For example, a glucose monitoring device can communication with an infusion pump assembly used to supply insulin or another medication to a user. In such circumstances, the data received from the monitoring device can be used to adjust the sensitivity of an occlusion detection system.

8. A method of operating an insulin infusion pump system, comprising:
-
activating an occlusion detection system to detect a fluid condition in a flow path extending from an insulin reservoir in a portable insulin pump apparatus to a user, the portable insulin pump apparatus including a pump drive system to dispense insulin through the flow path to the user; activating the pump drive system to deliver a first incremental dosage of insulin; in response to a first signal from the occlusion detection system indicating an occlusion in the flow path, increasing a counter value stored in a memory device of the portable insulin pump apparatus while foregoing output of an occlusion alarm; activating the pump drive system to deliver one or more subsequent incremental dosages of insulin; in response to a predetermined quantity of consecutive signals from the occlusion detection system indicating the occlusion in the flow path, outputting the occlusion alarm from portable insulin pump apparatus to the user receiving glucose information from a monitoring device, the glucose information being indicative of a detected blood glucose level of the user; and adjusting a sensitivity of the occlusion detection system based upon the glucose information from the monitoring device, wherein the sensitivity of the occlusion detection system is adjusted by altering a value of the predetermined quantity of consecutive signals from the occlusion detection system indicating the occlusion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
