1. A nasal continuous positive airway pressure (nCPAP) device comprising:

  • a hollow body having a proximal wall and a distal wall;

    an exhaust port extending through the distal wall of the body;

    a plurality of nozzles extending through the body and arranged such that a stream of gas entering the body through each nozzle impinge upon each other and combine to flow in a first direction proximal toward the proximal wall;

    a tubular member extending through the proximal wall of the body, the proximal tubular member comprising an inner cross-section defining a relief zone between the nozzles and proximal wall, and a tapering zone between the relief zone and the proximal wall, wherein a fluid flow a stream of gas entering the body through the proximal tubular member in a second direction that is opposite the first direction causes the combined stream of gas from the nozzles to separate and enter the relief zone.
