A surgical cassette (200) is provided having a fluid pressure sensing chamber (210) with a tubing extension (240) extending through the chamber. The tubing contains at least one port (260) that fluidly communicate(s) with the pressure sensing chamber, being adapted to allow the purging of air from the chamber during initial priming of the cassette, but being sized so that air bubbles entering the tubing extension cannot easily flow into the chamber. |
