Abstract:
An adjustable mask system (100) includes a cushion with a seal (130) having the ability to change size and/or shape. The seal is preferably a one-piece, continuous member without interruptions. To effect adjustment of the size and/or shape of the seal, an actuator may be provided, which may take the form of a dial (190).
Abstract:
Headgear (10) for a respiratory mask includes a strap arrangement including front strap portions (15) adapted to be disposed over a patient's cheeks and having front ends (35) adapted for attachment to an airway interfacing portion, top strap portions (20) connected to respective front strap portions (15) and adapted to be disposed over the top of a patient's head and to connect to each other, and a back strap (30) extending rearwardly from and connecting respective junctions of the front strap portions (15) and top strap portions (20) or regions adjacent these junctions and adapted to locate underneath a patient's occiput. In use with a patient having long hair, the back strap (30) is adapted to extend under the patient's hair and urge upwardly on the patient's hair and against the patient's head beneath the occiput. In use with a patient having short hair, the back strap (30) is adapted to urge against the patient's head beneath the occiput. In an embodiment, front strap portions (15) of the headgear may be provided with a sleeve or cover (e.g., constructed of a fleece material) to enhance comfort in use.
Abstract:
A mask system including a headgear and cushion module and a seal and frame module provided to the headgear and cushion module. The seal and frame module includes a sealing portion adapted to form a seal with the patient's face and a frame portion adapted to form a breathing chamber. The headgear and cushion module includes a cushion region adapted to support and shape the sealing portion and a headgear region adapted to support and stabilize the mask system on the patient's face.
Abstract:
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.
Abstract:
A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.
Abstract:
A mask system for use between a patient and a structure to deliver a breathable gas to the patient includes a mask assembly (50) including a frame (52), a cushion (54) provided to the frame (52), and optionally an elbow (56) provided to the frame (52). Headgear (10) is removably attached to the mask assembly (50) to maintain the mask assembly (50) in a desired position on a patient's face. The headgear (10) includes a back headgear section (20) providing a top strap (22), a pair of side straps (30, 32) attached to the back headgear section (20), and an elastic strap (40) attached between the back headgear section (20) and the pair of side straps (30, 32).
