ABSTRACT:
A smoke evacuator system for by-products of laser surgery including an inline construction of a motor and a filter assembly mounted on opposite sides of a mounting plate. The filter fits in a filter duct and the temperature of the flow between the filter and the vacuum chamber of the vacuum pump can be monitored to determine the clog condition of the filter. The system includes electronic circuitry to activate an alarm device to indicate to the user that the filter is clogged and further circuitry is provided to shutoff the motor after a long period of operation with a clogged filter to prevent damage to the system by overheating.
