Abstract:

The present invention relates to a system and method for improving glucose sensor accuracy by utilizing multiple calibration methods and selecting the most accurate method depending on a consensus glucose concentration estimate. Embodiments of the present invention comprise the steps of performing at least one in vivo update of surrounding glucose to acquire glucose values; calculating multiple updated calibration estimates using the updated glucose values; calculating an initial consensus glucose estimate from sensor output using each updated calibration estimate; applying a smooth crossover function to the multiple calibration estimates based on the value of the initial consensus glucose estimate; and adding weights to the multiple calibration estimates to acquire a consensus glucose estimate.

Abstract:

A medical fluid communication system is disclosed comprising a pump controller and a fluid detector. The fluid detector detects characteristics of the fluid and provides fluid measurements to the pump controller, which detects if the fluid is flowing in the medication delivery system. In the event fluid is not flowing due to an occlusion, the pump controller may attempt to resolve the occlusion or may provide a warning to a user that an occlusion is occurring.
