Systems and methods are provided for humidifying ventilation gas. Systems and methods may include a nasal interface apparatus for receiving ventilation gas from gas delivery tubing and for humidifying ventilation gas. The nasal interface apparatus may have one or more channels within the nasal interface to deliver gas from a gas delivery circuit to a patient's nose; one or more structures in fluid communication with the one or more channels to direct ventilation gas to the patient's nose; and a hygroscopic material within the nasal interface in the flow path of the ventilation gas.

In accordance with the present disclosure, there is provided a mask for achieving positive pressure mechanical ventilation (inclusive of CPAP, ventilator support, critical care ventilation, emergency applications), and a method for a operating a ventilation system including such mask. The mask of the present disclosure includes a piloted exhalation valve that is used to achieve the target pressures/flows to the patient. The pilot for the valve may be pneumatic and driven from the gas supply tubing from the ventilator. The pilot may also be a preset pressure derived in the mask, a separate pneumatic line from the ventilator, or an electro-mechanical control. The mask of the present disclosure may further include a heat and moisture exchanger (HME) which is integrated therein.

摘要:
An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae (2a, 2b), prongs, or pillows and may be sealed or unsealed with the nares of the patient in use. The cannula, pillows or prongs may be positioned on the face of the patient by a headgear (6). The cannula, pillows or prongs may be smaller, lighter, and/or less visible than other nasal cannula, cannulae, pillows or prongs and may therefore be less obtrusive to the patient.
摘要:
A continuous positive airway pressure (CPAP) apparatus for respiratory assistance of a pattern is disclosed. There is a blower having an output connectible to a ventilation mask wearable by the patient. A first pressure sensor measures blower pressure at the output of the blower, and a second pressure sensor that is connectible to the ventilation mask measures mask pressure therein. A pressure controller is connected to the first pressure sensor and the second pressure sensor, and a patient inspiratory phase and a patient expiratory phase is be detectable by the pressure controller to regulate therapeutic pressure at the patient mask, based upon pressure differentials between the mask pressure and the blower pressure.
摘要:
A mask system includes a frame (20) adapted to attach headgear, a sealing arrangement (40) releasably connectable to the frame, and an elbow (70) provided to the sealing arrangement and adapted to be connected to an air delivery tube that delivers breathable gas to the patient. The sealing arrangement defines a breathing chamber and is adapted to form a seal with the patient's face. The sealing arrangement includes structure (50) to establish a positive connection with the frame and with the elbow.
