ABSTRACT:
A device for detecting partial restriction in a fluid line connecting a fluid source with an IV infusion pump comprises a gauge mounted on the pump and operatively associated with the line to determine fluid pressure therein. The pump also comprises a peristable finger to conditionally occlude the line and a miroprocessor, upon occlusion of the line, to establish fluid pressure parameters within which the indication is that there is no partial restriction in the line. The pump also uses the microprocessor to compare actual pressure measured by the gauge during an occlusion with the established parameters to determine whether pump operation is to be continued.
