Abstract
A nasal continuous positive airway pressure (nCPAP) device having a hollow body with a proximal wall, a distal wall, and an exhaust port extending through the distal wall. A proximal tubular member extends through the proximal wall of the body and is arranged such that a stream of gas entering the body through the proximal tubular member will exit the proximal tubular member in a first direction and then enter the exhaust port. A nozzle extends through the body and is arranged such that a stream of gas entering the body through the nozzle will exit the nozzle and then enter the proximal tubular member in a second direction that is opposite the first direction.
