摘要：
An infant positive airway pressure (PAP) or continuous positive airway pressure (CPAP) device and related patient interface and system, which can provide a flow of breathing gas to the patient interface. The device can be incorporated into the patient interface and includes at least one interior passage in the shape of a nozzle having a throat, a first portion upstream of the throat and a second portion downstream of the throat relative to the flow of breathing gas. The passage has a vent opening within the second portion and the interior passage defines a continuously curved surface extending between the throat and the vent opening. The second portion of the nozzle preferably is divergent and the first portion can be convergent or non-convergent (e.g., constant cross-section).
