摘要:
A respiratory mask includes a frame and a flexible structure provided to the frame and adapted to engage a patient's face. The flexible structure includes a chamber filled with a first gel and a second gel that is relatively harder than the first gel. A ratio of height of the first gel to the second gel in a lip region is in the range of about 0.25 to about 0.6.

A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the patient's nares; a pair of strips configured to be connected to opposite sides of the patient interface structure; and adhesive configured to secure the patient interface structure in sealing engagement with the patient's nares. The adhesive may be provided on the strips, and the strips are configured to be adhered to sides of the patient's nose by the adhesive. Another patient interface system includes a first component including adhesive on a first side and hook or loop fastener material on a second side, wherein the adhesive is configured to adhere the component to the face of the patient; and a patient interface structure configured to sealingly engage the patient's airways. The patient interface structure includes a second component including a corresponding loop or hook fastener material configured to engage the corresponding hook or loop fastener material of the first strip to secure the patient interface structure in sealing engagement with the patient's face. A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure including a pair of nasal prongs or pillows configured to sealingly engage the patient's nares; and at least one spring configured to bias the nasal prongs or pillows outwards into engagement with the nares of the patient.

A swivel elbow and connector assembly for a patient interface system includes a ring configured to be sealingly secured in an aperture of the patient interface system. The ring includes a first side in an interior of the patient interface system and a second side at an exterior of the patient interface system when the ring is secured in the aperture. The ring also includes a plurality of vents configured to permit flow of gases from the interior to the exterior of the patient interface system. The swivel elbow and connector assembly includes an elbow swivelably secured in the ring. A patient interface system for delivering a flow of breathable gas to a user includes a patient interface structure configured to sealing engage the face of the user. The patient interface structure includes an aperture. A swivel elbow and connector assembly is sealingly secured in the aperture.

摘要:
A control system (706) provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly (60) of the system may include a variable exhaust area such as one defined by overlapping apertures of the assembly or a conduit having a variable gas passage channel. The vent assembly may be formed by nested structures, such as conic or cylindrical members, each having an opening of the overlapping apertures. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid or voice coil, manipulates an aperture of the vent assembly. The actuator may be configured for control by a controller to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection, rebreathing volume calculation and/or leak detection.

A mask system includes a frame and a cushion provided to the frame. The frame provides a brace or fulcrum like structure about which the cushion may pivot, bend, and/or flex.
摘要:
A mask cushion or a mask assembly therewith provides a comfortable and effective seal for provision of a gas therapy by a respiratory treatment apparatus. The mask cushion (102) may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component (104). The mask cushion also includes a patient facial-contact side portion with a chamber (108) and a barrier (106) to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.
