Irrigation system with tubing cassette

摘要

An irrigation system for use in endoscopic procedures for maintaining and controlling flow of irrigation fluid to an internal body irrigation site. The system includes a tubing set comprising inflow and outflow lines and a cassette, and an fluid control module comprising a race and a pumping mechanism that squeezes the inflow line of the tubing set against the race to pump fluid to the irrigation site. The cassette includes a through opening exposing a portion of the inflow line to the race and pumping mechanism so that the cassette merely holds the inflow line in alignment with the pumping mechanism but is not required to resist the compressive force of the pumping mechanism. The cassette may include a second through opening exposing a portion of the outflow line to a valve mechanism to regulate pressure independently of the pump mechanism, and rib-or-groove alignment mechanism to align the inflow line with the pumping mechanism and the outflow line with the valve mechanism.
