ABSTRACT:
An infusion system for infusing a flowable material into a patient comprising an infusion device for delivering the flowable material in both a normal delivery pattern and a test pulse and a conduit for conducting the flowable material from the infusion device to the patient. The test pulse creates a pressure wave response in the conduit. The pressure wave response is monitored and used to detect if the infiltration has occurred.
