US 2022/0031902 A1 · Dental/medical operatory ventilation system

Abstract

A ventilation system for removal of aerosols including bacteria and viruses such as the COVID-19 Coronavirus, and airborne debris from dental/medical operatories is provided. This ventilation system is comprised of (1) a stationary hood, secured at a specific distance above a patient that pulls contaminated air from the operatory, (2) ducting that carries the contaminated air away from the operatory, (3) a UV Ozonator that treats the air and cleans it of viral and bacterial aerosols and airborne debris before (4) expelling it to the outside through a specified length of terminal duct. The combination of certain embodiments in this invention create an effective means of aerosol and airborne debris removal in dental/medical operatories or other indoor spaces.
