Abstract

A centralized system for removing the plume resulting from laser surgery, electrocauterization or orthopaedic surgery that takes advantage of the articulating arms frequently found in medical procedure rooms. The plume is drawn away from the surgery location by a vacuum. The tubing that carries the plume is held near the location of the medical procedure, and the plume is then drawn into the tubing. The tubing leads through the articulating arm to a main located above the ceiling. The main leads to a central room that includes, in series, a centrifugal separator, a vacuum producer and a high efficiency air filter.
