SURGICAL FLUID MANAGEMENT

摘要

A fluid flow device includes a housing configured to releasably mate with a surgical control unit for controlling fluid flow during a surgical procedure. First and second ports measure fluid pressure within a fluid path provided within the housing. The fluid flow device includes a restrictor for restricting fluid flow at a restriction location along the fluid path. The first port is located upstream of the restriction location and the second port is located downstream of the restriction location. A fluid pump is provided within the housing.

1. A pump cassette for releasably mating with a surgical control unit, the control unit defining a cassette receiving slot with a guide track and comprising first and second pressure transducers, the pump cassette comprising:
a housing having a protrusion configured and arranged to mate with the guide track during introduction into and final placement within the slot such that the housing is spaced from the pressure transducers during introduction into the slot and contacts the pressure transducers when in final placement within the slot; and first and second ports positioned for alignment with the first and second pressure transducers when the cassette is in final placement within the slot.
