Abstract
A continuous positive airway pressure system features a housing forming an airway chamber, and an air pressure inlet and an air pressure outlet. The housing further defines internally a pair of tapered air jets, and a pair of tapered air receivers. The air receivers are located downstream of the air supply jets and disposed coaxially with respective ones of the air supply jets. Each receiver has a taper in an opposite direction to the direction of the taper of the air supply jets. A pair of nasal prongs is located downstream of the air receiving jets. Each receiver comprises a hemispherical section that is oriented at an angle off the center line of the supply.
