Abstract:
A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure; a frame member attachable to the retaining structure; and a positioning and stabilising structure attachable to the frame member.
Abstract:
Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The at least one gas delivery tube may be constructed and arranged to contact, in use, at least a region of the patient's head superior to an otobasion superior of the patient's head. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads. The positioning and stabilising structure may comprise a bias mechanism to impart a biasing force along at least a part of a length of the at least one gas delivery tube to urge the seal-forming structure towards the entrance of the patient's airways in use.
Abstract:
A patient interface system to treat a respiratory disorder of a patient, the patient interface system comprising: a positioning and stabilising structure including a back portion and a pair of upper straps extending from the back portion; and a patient interface including a patient interface frame and a pair of rigidiser arms each connected to the patient interface frame at a connection point located in a plane substantially parallel to the patient's Frankfort horizontal plane, the pair of rigidiser arms further including a pair of upper attachment points, wherein the pair of upper straps are adapted to be releasably attached to the pair of upper attachment points such that, when donned by the patient, the pair of upper straps are vertically offset relative to the connection points and substantially parallel to the patient's Frankfort horizontal plane, and wherein the patient interface does not include a forehead support.
