摘要： The present invention provides a vent assembly suitable for use with a respiratory mask of the type used in CPAP treatment. In one embodiment the vent is made of a thin air permeable membrane. Generally, the membrane is thinner than 0.5 mm. The membrane can be made of a hydrophobic material such as polytetrafluoroethylene (PTFE). The membrane can also be fabricated from expanded PTFE. The expanded PTFE membrane is mounted on a polypropylene scrim. The pores of the membrane have a reference pore size of 10 to 15 microns. In an alternative embodiment, the vent assembly includes a vent constructed from stainless steel. In another embodiment the membrane has a superficial cross-sectional area of approximately 500 mm2. In another embodiment the vent assembly comprises a membrane attached to a vent frame, the vent assembly forming an insert which can be removably attached to a mask frame.

摘要： A vent assembly for use with a respiratory mask of the type used in CPAP treatment. In one embodiment, the vent is made of a thin air permeable membrane (28). The membrane can be made of a hydrophobic material such as expanded polytetrafluoroethylene (PTFE). An expanded PTFE membrane is mounted on a polypropylene scrim. The pores of the ePTFE membrane have a reference pore size of 10 to 15 microns. Alternatively, the vent assembly includes a stainless steel vent having holes with diameters less than about 0.2 mm. In another embodiment, the membrane has a superficial cross-sectional area of approximately 500 mm2. In further embodiments, a vent of a mesh material, e.g., an auxetic vent (200) or a PTFE mesh, may be used as an air permeable membrane, either alone or in combination with a traditional vent structure.

摘要： A flow generator and humidifier construction is described, including a flow generator construction adapted to reduce noise output compared to known flow generators of comparable size. The flow generator includes a chassis forming first and second muffler volumes and a venturi-shaped connection portion, and a metal/polymer composite material blower enclosure which suppresses noise from the blower. The flow generator may be programmed to include a reminder system including a menu from which the user may request a reminder to take specific action, e.g., replace a component, call a physician, and/or enter patient data card, etc.

摘要： A variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

摘要： A humidifier is provided including a first humidifier part, a second humidifier part connectable with the first humidifier part, and a sealing gasket disposed between the first and second humidifier parts. The second humidifier part is configured to hold a volume of liquid therein and the first and second humidifier parts and the sealing gasket define first and second internal passages within the humidifier. The first passage is disposed so as to be exposed to a surface of the volume of liquid and the second passage is isolated from at least one of the first passage and the surface of the volume of liquid. The second passage is configured to communicate with a pressure and/or sound sensing device.
