Abstract

DISPOSITIVO DE RESPIRACION ASISTIDA QUE CONSTA DE UN GENERADOR DE GAS RESPIRATORIO QUE INCORPORA ELEMENTOS PARA EL ESTABLECIMIENTO, DURANTE UNA FASE INSPIRATORIA, EN UN CONDUCTO DE ALIMENTACION QUE DESEMBOCA EN UN ORIFICIO INSPIRATORIO ASOCIADO A UNA VALVULA DE EXPIRACION, DE UNA PRESION SUSTANCIALMENTE CONSTANTE DEL GAS RESPIRATORIO CUALQUIERA QUE SEA EL CAUDAL DEL GAS INSPIRATORIO. SE CARACTERIZA EN QUE LOS ELEMENTOS DE ESTABLECIMIENTO DE UNA PRESION SUSTANCIALMENTE CONSTANTE CONSTAN DE UN EYECTOR (1) CONVERGENTE-DIVERGENTE QUE DESEMBOCA EN DICHO CONDUCTO DE ALIMENTACION. CONTRARIAMENTE A LOS VENTILADORES DE MULTIPLES MODOS DE VENTILACION GENERALMENTE PARA ENFERMOS INTUBADOS O TRAQUEOTOMIZADOS, EL INVENTO ESTA PENSADO PARA ENFERMOS UNIDOS AL DISPOSITIVO POR UNA SIMPLE MASCARA QUE RECOGE LA NARIZ Y LA BOCA, UNA MASCARA NASAL O UNA BOQUILLA.
