AI Technical Summary
Benefits of technology
The present technology aims to have multiple functions in one part, such as a quick release button, baffle, and swivel all formed together, which reduces the need for disassembly and lowers costs. Additionally, the technology includes a cushion for the nasal mask that avoids high sealing forces on the sides of the nose or ridge, which could cause nasal airway occlusion.
Problems solved by technology
It often causes excessive daytime somnolence, and it may cause cardiovascular disease and brain damage.
It is possible that CSR is harmful because of the repetitive hypoxia.
In some patients CSR is associated with repetitive arousal from sleep, which causes severe sleep disruption, increased sympathetic activity, and increased afterload.
Some NMD patients are characterised by progressive muscular impairment leading to loss of ambulation, being wheelchair-bound, swallowing difficulties, respiratory muscle weakness and, eventually, death from respiratory failure.
Symptoms of respiratory failure in NMD include: increasing generalised weakness, dysphagia, dyspnoea on exertion and at rest, fatigue, sleepiness, morning headache, and difficulties with concentration and mood changes.
Chest wall disorders are a group of thoracic deformities that result in inefficient coupling between the respiratory muscles and the thoracic cage.
Scoliosis and / or kyphoscoliosis may cause severe respiratory failure.
Symptoms of respiratory failure include: dyspnoea on exertion, peripheral oedema, orthopnoea, repeated chest infections, morning headaches, fatigue, poor sleep quality and loss of appetite.
Known patient interface devices suffer from being one or more of obtrusive, aesthetically undesirable, poorly fitting, difficult to use and uncomfortable, especially when worn for long periods of time or when a patient is unfamiliar with a system.

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 and an elbow swivelably secured in the ring. 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 comprises a first flange on the first side and a second flange on the second side, the first and second flanges defining a channel that sealingly engages the aperture of the patient interface system. An inner surface of the ring is partially spherical and an outer surface of the elbow is partially spherical and the elbow and the ring form a ball and socket connection.
