摘要:
599608 Apparatus for providing positive airway pressure therapy to the airways of a patient, comprising: a mask; a gas delivery conduit coupled to the mask; and a vent located in the mask or near the mask in the gas delivery conduit, to allow washout of exhaled carbon dioxide. The vent comprises a plurality of vent orifices (2006, 2008). The vent orifices are constructed and arranged to be open in use at least during the inhalation and exhalation phases of the user's breathing cycle. The vent orifices are molded into a curved surface so that a vent flow from each of the orifices is directed in different directions, into one another, and/or slightly offset from one another to create diffuse air flow.
