System Description

Section 1.0
1.1 Introduction
BUFFALO FILTER® ViroVac Smoke Evacuation Systems are intended to evacuate and filter surgi-
cal smoke plume and aerosols created by the interface surgical tools with tissue, examples being
lasers, electrosurgery systems, and ultrasonic devices.
The ViroVac Smoke Evacuation Systems have been designed with a high suction, high flow rate
vacuum motor. 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 from .1 to .2
microns at an efficiency of 99.999%.
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 tis-
sues. These harmful gases may constitute a health hazard to healthcare professionals who are
subjected to prolonged exposure. The activated carbon used in the ViroVac™ 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 ViroVac™ Smoke Evacuation System has been
designed "user friendly" and facilitate unit set up and operation. Please refer to Section 2.0 for
Operating Instructions.
