Abstract:
1. A surgical system comprising: a fluid detector system comprising a first emitter and a first signal receiver and a second emitter and a second signal receiver, wherein the first emitter is configured to emit a first color and the second emitter is configured to emit a second color, or the first emitter and first signal receiver are configured to employ light having a first polarization and the second emitter and second signal receiver are configured to employ light having a second polarization; and a cassette including a fluid container having a first wall and a second wall with a volume portion therebetween; the system configured to produce a first signal and a second signal when a light beam transmits through the first wall, the volume portion, the second wall, and into the first or second signal receiver; the system configured to produce a second signal when the second wall directs the light beam away from the first or second signal receiver by refraction and/or reflection; wherein the first emitter and first signal receiver are disposed at a first vertical height relative to the fluid container, and the second emitter and second signal receiver are disposed at a second vertical height, the second vertical height below the first vertical height to detect differing quantities of fluid in the fluid container.
