Abstract
The invention is a method of identifying whether a particular fluid collection cassette is designated to have a particular use, such as posterior surgery or anterior surgery. A reflux bulb attached to a fluid collection cassette has a material disposed on or in said reflux bulb in a predetermined location. When the reflux bulb is disposed on the fluid collection cassette, and the fluid collection cassette inserted into a housing, a sensor attached to the housing senses the existence, or non-existence of the material and sends a signal conveying the information to a main controller.
