Reducing hospital infections with Toul Laminar Air Flow

Toul technology provides a horizontal ultraclean laminar airflow which is directed directly over the surgical site and instruments, acting as a barrier and minimizing the presence of bacteria-carrying particles at the wound. An easy to use control system helps the user direct airflow in the most effective way: a camera assists in determining airflow direction and an integrated sensor determines the correct distance from the surgical site for maximum effect. A touch-screen display allows the user to check and verify the set-up. Ambient air is passed through a HEPA filter and a Laminar Air Flow (LAF) screen. The ultraclean air leaves the screen as a laminar (turbulence-free) flow, pushing contaminated air forwards, away from the risk zone and into the room, to be absorbed by the conventional ventilation system. Sterile, single-use LAF screens guarantee sterile flow.

Operating Room
Every minute, an individual emits thousands of airborne particles carrying bacteria that may contaminate an open surgical wound. Ironically, the use of ultraclean airflow may help to convey airborne particles from the surgical team into the operating field and thereby increase direct airborne contamination of the wound.


Toul 400 Laminar Airflow
Toul is positioned very close to the operating field and therefore it is possible to reduce the contamination level by almost 95 % for the operating field and Toul instrument table because Toul is not hindered by the surgical light and the heads of the operating team.





LAF Screen
To ensure the maximum sterility a sterile laminar flow screen is put in front of the unit before the operation starts
