Abstract: One of the main problems of hoods and central ventilation devices for dental offices and clinics is the lack of fluid suction between the patient and the dentist during the spraying of the aerosol and droplet. This disclosure provides a solution to build a new device using technologies that follow the principles of ergonomics in designing and using the calculated discharge system to limit the movement of the aerosol and the droplet. This device proposes an isolation process whereby fluid transfer, along with the contaminated particles attached to the negative ions, are trapped in the chamber and transfer to the filter due, to prevent diffusion to the environment. This device also utilizes and control of optimal parameters of heat and light and negative ions, ultraviolet and ozone to sterilize and eliminate viruses and bacteria.
