Purpose
The purpose of the ViroVac © Surgical Smoke Evacuator is to evacuate and filter surgical smoke and aerosols created by the interface of the surgical tools with tissue (examples: lasers, electrosurgery systems, and ultrasonic devices). The ViroVac © Surgical Smoke Evacuator has been designed to provide the appropriate suctioning using one of the three motor speeds to manage surgical smoke. The ultra-quiet motor is used to draw the surgical smoke from the surgical site through the vacuum tubing and into the filter where the surgical smoke is processed through four (4) stages of filtration. A single, completely enclosed, disposable filter is used to simplify installation and removal during filter changes to protect healthcare personnel from potential contamination during filter changes.
1. The first-stage filtration utilizes a pre-filter to trap and remove gross particulate and casual fluid.
2. The second-stage filtration is an Ultra Low Penetration Air (ULPA) filter with a high-tech patented design that captures particulates and micro-organisms from 0.1 to 0.2 microns at 99.999% peak efficiency.
3. The third-stage filtration uses the highest grade virgin activated carbon. The activated carbon is known to remove toxic organic gases and may provide optimal odor removal.
4. The fourth-stage filtration is a woven fiberglass filtration media used to reduce the amount of activated carbon fines from migrating out of the filters.
The intended use depends on the approval of the country. Refer to the instructions for use of the ViroVac © Surgical
Smoke Evacuator and its accessories.
