Abstract
The present invention provides a respiratory adapter for inhaled media deposition in the lungs and airways. The respiratory adapter provides an inspiratory arm and an expiratory arm, wherein the two arms are joined by a bypass flow bridge. A system of valves, such as one-way valves, directs the flow of gas and media through the respiratory adapter to improve media deposition efficiency and to prevent re-breathing of exhaled gas.
Claims27
A respiratory adapter for inhaled media deposition comprising:
- an inspiratory arm having a first end connectable to a ventilator and a second end connectable to a subject/patient breathing interface;
- an expiratory arm having a first end connectable to a ventilator and a second end connectable to the subject/patient breathing interface;
- a bypass flow bridge fluidly connecting the inspiratory arm and the expiratory arm between their first and second ends;
- a media port positioned in the inspiratory arm between its second end and the bypass flow bridge;
- and
- one or more valve positioned in each of the bypass flow bridge, in the inspiratory arm, and in the expiratory arm.
