| چکیده | ||
| In the wake of the COVID-19 pandemic, maintaining hygienic dental practice environments has become imperative due to the risk of SARS-CoV-2 exposure to dentists and patients. A novel infection control system has been developed, combining far-UVC light with an infrared-based hot air blower, aimed at significantly reducing pathogen spread in dental settings. This groundbreaking system leverages the germicidal properties of 222 nm far-UVC light known for inactivating viruses on surfaces and within aerosols, while circumventing the limitations posed by droplet size and composition through the strategic use of a hot air chamber. The invention includes an integrated built-in air suction device at the dental chair’s headrest for removing contaminated air, a circular floor-level suction system for enhanced air circulation, and a state-of-the-art 222 nm far-UVC lamp within established safety parameters. The hot air chamber’s primary function is to decrease droplet size via evaporation, thus augmenting 222 nm far-UVC light penetration to effectively neutralize pathogens. A supporting blower system evenly distributes the hot air for consistent droplet exposure to far-UVC light, while a HEPA-based air purifier re-circulates purified air back into the clinic. This integrated system not only aims to provide a safer environment by minimizing airborne transmission of viruses but also stands as a vital evolution in infection control within the dental industry. Its implementation in dental practices could revolutionize standards of care and patient safety in the ongoing global effort to mitigate infectious healthcare risks. | ||
