Abstract

Un dispositivo nCPAP para ayudar a la respiración de un paciente incluye un cuerpo de generador que forma una entrada, una cámara y circuitos de flujo primero y segundo. La cámara dirige gas presurizado de la entrada hacia los circuitos de flujo. Los circuitos de flujo incluyen cada uno una boquilla, un canal y al menos un puerto. La boquilla emite una corriente de chorro hacia el canal en la dirección de un lado del paciente. El puerto conecta de manera fluida el canal al ambiente, y promueve el arrastre de aire ambiental con la corriente de chorro. En algunas modalidades, el canal forma una característica de rampa que dirige el aire exhalado hacia la corriente de chorro en una forma angular. El cuerpo de generador requiere presiones de impulsión reducidas para lograr los niveles CPAP objetivo y reduce el WOB total impuesto en comparación a los diseños convencionales.
