  • there is two LED lights on the collar unit to providing lighting in dark areas.
  • Level 2 PPE protection requires an individual to attach the helmet without a face shield to the collar unit. With the vacuum fan on in the helmet, any contaminated air inside of the helmet will be vacuum into helmet’s filters and pass across a germicide UVC lamp before exiting into the surrounding environment. Level 2 is designed to protect an individual against the above-mentioned protection items even if the individual is infected with a contagious disease but without needing to wear a physical face covering. Level 3 provides both PAPR and PPE as result of attaching an air-tight face shield to the helmet. In the PAPR mode all major components are connected as a respirator system where the air flow rate and air pressure are regulated by a CPU controller that receives a user’s heart rate data from a heart rate monitor worn by the user.

Abstract

L'invention concerne un respirateur portable purificateur d'air (RPPA) commandé par téléphone intelligent pourvu d'un équipement de protection personnelle (EPP) et d'un éclairage germicide UVC. Le RPPA présente deux ventilateurs d'admission qui tirent de l'air extérieur dans une boîte à air qui présente des filtres destinés à éliminer les polluants, les bactéries, les agents pathogènes en suspension dans l'air et qui utilise ensuite une lumière UVC pour désactiver toute bactérie, pathogène et virus en suspension dans l'air restant. Le niveau 1 de protection est une unité d'EPP en collier portée autour de l'épaule d'un individu en vue de fournir 360 degrés d'air nettoyé. La protection de niveau 2 est une protection de casque sans écran facial qui se fixe à l'unité de collier et qui fournit la même filtration que celle mentionnée ci-dessus avec un éclairage UVC. La protection de casque aspire l'air provenant de l'unité de collier et le nettoie avant d'évacuer l'air. Le niveau 3 est un RPPA qui atteint une protection maximale par ajout d'un écran facial transparent à la protection de casque et la fourniture d'une pression positive d'air sur la base d'une fréquence cardiaque.
