ABSTRACT
ABSTRACT During the current coronavirus epidemic, personal protective equipment has become a vital issue. Depending on the procedure, the generation of aerosols increases the risk of infection for healthcare professionals. However, in dentistry, there is a high risk of contamination from blood or tissue fluids, generated in surgical procedures with ultrason ic and high-speed cutting devices. Thus, the creation of a prototype with a functional respiratory protection system offers filtered air at the entrance and exit of the circuit, also benefiting the patient. This experimental and unprecedented air purification system has 99.9 % high efficiency filters, positive and negative pressure control and also generates an internal balance of air flow; its purpose is to maintain the facial seal of the snorkel mask. The results showed that this air purificat ion system could be an option in environments contaminated by aerosol caused by rotary intruments in dentistry.
RESUMEN
RESUMEN Durante la actual epidemia de coronavirus, el equipo de protección personal se ha convertido en un problema vital. Dependiendo del procedimiento, la generación de aerosoles aumenta el riesgo de infección para los profesionales de la salud. Sin embargo, en odontología, existe un alto riesgo de contaminación por sangre o fluidos tisulares, generados en procedimientos quirúrgicos con dispositivos de corte ultrasónicos y de alta velocidad. Por lo tanto, la creación de un prototipo con un sistema funcional de protección respiratoria ofrece aire filtrado a la entrada y salida del circuito, lo que también beneficia al paciente. Este sistema de purificación de aire experimental y sin precedentes tiene 99.9 % de filtros de alta eficiencia, control de presión positiva y negativa y también genera un equilibrio interno del flujo de aire; Su propósito es mantener el sello facial de la máscara de snorkel. Los resultados mostraron que este sistema de purificación de aire podría ser una opción en ambientes contaminados por aerosoles causados por instrumentos rotativos en odontología.
