Laser Plume Capture for the Veterinary Practice

Laser surgical instruments are commonplace in today’s veterinary practice. Because laser instruments can vaporize tissue, there is concern about the content of the smoke plume they produce.

OSHA also notes that although there has been no documented transmission of infectious disease via surgical smoke, the potential for generating infectious viral fragments, for example, may exist.

Point-of-origin solutions

In the scenario OSHA describes, a point-of-origin solution for removing the plume from the veterinary operating room is an appropriate recommendation for veterinary practitioners concerned about operating room safety.

For those laser instruments that include a suction nozzle with internal fan and an exhaust port, our units can connect directly to the instrument, pulling the plume into filters that help to prevent contaminants from spreading to the wider work area.

The plume can also be contained by placing the source capture hood of a Sentry Air Portable Floor Sentry adjacent to the site of the surgery to capture the plume as it is created, directing impurities into the unit’s filter system. Filtration media for these systems depends upon the application being performed, but typically involves HEPA filtration [up to 99.97% efficient on particles 0.3 microns and larger] and Activated Carbon filters.

This approach to safety in medical environments is also used in other practices. Here’s a link that describes source-capture fume extraction by a podiatrist who uses a laser to treat his patients. You can read his testimonial as well as that of a lab manager who says our portable SS-200-FS Floor Sentry is “extraordinarily effective” at lowering exposure to anestheticand dental acrylic used during surgical procedures.

Model SS-200-FS Floor Sentry 

The Model SS-200-FS Floor Sentry has several features that make it a good fit for medical workspaces. Its self-supporting, flexible source-capture arm can be placed directly adjacent to the source of fumes.

A Greater Air Volume, Stackable Filters Solution

Like the Model SS-200-FS, our larger Model # SS-300-PFS Floor Sentry provides laser plume capture and filtration of airborne contaminants during veterinary laser surgery.

Model SS-300-PFS Portable Floor Sentry
The unit’s greater air volume capability ranges from its high rate of 350 CFM (cubic feet per minute) to 50 CFM at its lowest setting. This source-capture fume extractor includes heavy-duty casters for easy mobility. Multiple filters can be housed inside the filter chamber for applications that emit both particulates and fumes; media options include HEPA, ASHRAE filtration [up to 95% efficient on particles 0.5 microns and larger], Activated Carbon, and specialty-blended filter media [i.e., acid gas, mercury, aldehyde, ammonia].
