NASAL CONTINUOUS POSITIVE AIRWAY PRESSURE DEVICE

摘要

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.

1. A nasal continuous positive airway pressure (nCPAP) device comprising:
a body having a proximal end and a distal end, a chamber at the proximal end of the body, and a first passage extending from the chamber through the distal of the body; a plurality of nozzles fluidly coupled to the first passage, between the chamber and the distal end of the body, the plurality of nozzles arranged to direct a fluid flow into the first passage such that the fluid flow from each nozzle impinges upon each other and combines to flow through the first passage toward the distal end of the body; wherein an opposing fluid flow through the first passage from the distal end toward the proximal end of the body redirects the fluid flow from each nozzle to flow toward the chamber.
