Surgical fluid management
First Claim
1. A method of mating a pump cassette to a surgical control unit, the surgical control unit defining a cassette receiving slot with a guide track and having first and second pressure transducers, comprising:
- aligning a protrusion on the cassette with the guide track and pushing the cassette along the guide track such that the cassette moves parallel to the cassette receiving slot and spaced apart from the pressure transducers; and
thenpushing the cassette further along the guide track such that the cassette moves toward to the pressure transducers to a final placement in contact with the pressure transducers; and
aligning a pinch valve cutout on the pump cassette with a pinch valve disposed on the control unit as the cassette is introduced into the slot.

Abstract
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.

7. A method of mating a pump cassette to a surgical control unit, the surgical control unit defining a cassette receiving slot with a guide track and having first and second pressure transducers, comprising:
-
aligning a protrusion on the cassette with the guide track and pushing the cassette into the guide track such that the cassette moves from a position spaced from the pressure transducers during introduction into the slot to a final placement in contact with the pressure transducers; aligning a pinch valve cutout on the pump cassette with a pinch valve disposed on the control unit as the cassette is introduced into the slot; and aligning a leading edge of a microswitch disposed on the control unit with a cassette insertion recognition recess defined in the cassette. - View Dependent Claims (8)
