ABSTRACT:
The present invention provides a stand-alone, in-line device and method for detecting whether a fluid is being properly supplied to a patient, including means for delivering a test pulse of the fluid through conduit means to the patient with the test pulse being distinguishable from the normal delivery pattern and with the test pulse creating a pressure wave response in the conduit means. The device and method also includes means for determining the area between a baseline and at least a portion of a pressure versus time curve representing the pressure wave response, and means responsive to the magnitude of the area for detecting whether the fluid is being improperly supplied by the conduit means to the patient. Preferably, the device and method also includes means for diverting and accumulating a predetermined volume of the upstream flow from the infusion source for use as the test pulse.
