Abstract

Se describe un sistema de inyección (100) para la administración de una sustancia gaseosa (112) al sistema respiratorio de un paciente. El sistema de inyección (100) incluye una unidad de control (102) y un ensamblaje de válvula (104) que incluye una válvula (160) y un actuador de válvula (162) que permite la apertura parcial de la válvula (160) y que está controlado por la unidad de control (102). A la unidad de control (102) se le suministran datos del flujo gaseoso y controla el ensamblaje de válvula (104) de manera que la apertura de la válvula (160) es función del flujo de gas, que permite regular la concentración de la sustancia gaseosa (112) administrada al paciente (116).
