Resumen
La Organización Mundial de la Salud (OMS) declaró un estado pandémico de salud pública debido a transmisión del nuevo coronavirus el 11 de marzo de 2020. La COVID-19, causada por el SARS-CoV-2, tiene un espectro clínico muy amplio, con predominio de desarrollos sintomáticos respiratorios. El papel de los profesionales de salud en la lucha contra la pandemia requiere un equipo de protección personal (EPP). Las máscaras PFF2 / N95 son EPP adecuados para este propósito. Debido a gran demanda de máscaras PFF2 / N95 para combatir la pandemia, hubo escasez en el mercado. Este trabajo tiene como objetivo caracterizar un dispositivo denominado DELUX para la esterilización por UVC (espectros de luz ultravioleta C) de mascarillas PFF2 / N95, ampliando su tiempo de uso seguro en condiciones de emergencia. La validación fotométrica del dispositivo permitió la verificación del espectro de emisión de las lámparas empleadas en el dispositivo y la medición de la potencia óptica, demostrando la idoneidad de la irradiación con luz UVC, en ciclos de 15 minutos, de forma segura. La validación biológica mostró que DELUX es capaz de desactivar el SARS-CoV-2 presente en la superficie de las mascarillas PFF2 / N95, siendo así eficiente para su esterilización extendiendo el tiempo de utilización de estas mascarillas.
