SYSTEM AND METHOD FOR DETECTING OCCLUSIONS IN A MEDICATION INFUSION SYSTEM USING PULSEWISE PRESSURE SIGNALS

摘要

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.

1. A medication infusion system comprising:
a pump controller for providing medication fluid to a patient via a fluid path connected between a fluid reservoir of the pump controller and a patient; and an in-line fluid detector for measuring pressure of the medication fluid in the fluid path and transmitting the measured pressure to the pump controller, wherein the pump controller determines if a flow of the medication fluid is successful or unsuccessful based on the pressure measurements in a current interval.
