FLUID COLLECTION CASSETTE IDENTIFICATION SCHEME

摘要

This invention is a method of identifying whether a particular fluid collection cassette (10) is designated to have a particular use, such as posterior surgery or anterior surgery. A reflux bulb (26) attached to a fluid collection cassette has a material disposed on or in said reflux bulb in a predetermined location. A sensor attached to the housing senses the existence, or non-existence of the material and sends a signal to a controller.
