System and method for detecting occlusions in a drug infusion system using a pulsed pressure signal

摘要

A medical fluid communication system (100) comprising a pump controller (105) and a fluid detector (125) is disclosed. The fluid detector (125) detects fluid characteristics and provides fluid measurements to the pump controller (105), which detects whether fluid is flowing through the drug delivery system. To do. In the event that fluid is not flowing due to an occlusion, the pump controller (105) can attempt to clear the occlusion or provide a user with a warning that an occlusion has occurred.
