A method and apparatus for occlusion monitoring in a flow circuit using pressure waveform analysis. The flow circuit includes a first conduit and a second conduit which fluidly interconnects a fluid supply with the first conduit. A pump is disposed in an intermediate portion of the second conduit. Monitoring of the pressure in the first conduit is used to identify any occlusions in that portion of the second conduit which is disposed between the pump and the fluid supply.
L'invention porte sur un procédé et un appareil de surveillance des occlusions par analyse des ondes de forme de pression. Le circuit du liquide comporte une première conduite, ainsi qu'une deuxième conduite reliant une source de liquide à la première conduite. Une pompe est montée dans une partie intermédiaire de la deuxième conduite. L'observation de la pression dans la première conduite permet d'identifier toute occlusion se produisant dans la partie de la deuxième conduite placée entre la pompe et la source de liquide.
