System Description Section 1.0

1.1 Introduction The BUFFALO FILTER® PlumeSafe Smoke Evacuation Systems are designed to remove smoke and

noxious odors produced by surgical smoke during laser and electrosurgical procedures. The PlumeSafe Smoke Evacuation Systems have been designed with a high suction, high flow rate centrifugal action pump. The ultra-quiet motor is used to draw the surgical smoke from the surgical site through the vacuum tubing and into the ViroSafe® filter where the surgical smoke is processed by a series of filters. A single disposable filter is used to simplify the installation and removal during filter changes. The filter is completely enclosed to protect the healthcare personnel from potential contamination during filter changes. One Buffalo Filter ViroSafe filter contains four different stages within to capture the smoke plume. The first stage filtration is a prefilter whose function is to trap and remove gross particulate and casual fluid. The second stage filtration is ULPA grade (Ultra Low Penetration Air) filter whose high-tech patented (U.S. Patent #5874052) design captures particulates and micro-organisms down to 0.12 µm at an efficiency of 99.999%. Each ULPA grade filter is pretested and certified before use. The third stage filtration uses the highest grade virgin activated carbon, especially designed for Buffalo Filter for the removal and adsorption of odors and toxic gases produced by burning tissues. These harmful gases may constitute a health hazard to healthcare professionals who are subjected to prolonged exposure. The activated carbon used in the PlumeSafe Smoke Evacuation Systems preferentially removes toxic organic gases rather than water vapor and provides optimal odor removal. The fourth stage filtration is an expanded foam used to trap activated carbon fines from migrating out of the filter. The electronic controls on the face panel of the PlumeSafe smoke evacuation system has been designed “user friendly” and facilitate unit set up and operation. Please refer to Section 2.0 for Operating Instructions. 1.2 Inspection The PlumeSafe Smoke Evacuator has been thoroughly tested and inspected before shipment from the factory. Please check the unit before using it to insure that no damage has occurred in transit.
