摘要： A patient interface assembly is configured to deliver a positively pressurized flow of breathable gas to a patient's airways. The patient interface assembly includes a patient interface configured to sealingly engage the patient's face and comprises a chamber configured to receive the pressurized flow of breathable gas. The patient interface assembly also includes headgear configured to support the patient interface on the patient's head and be tightened to one of a plurality of discrete tension settings. The headgear includes a tensioning element that is configured to contract in length to one of a plurality of discrete lengths when subjected to an electrical signal. Each discrete length of the tensioning element corresponds to a respective one of the plurality of discrete headgear tension settings.

摘要： A gas delivery component of a CPAP system is configured to magnetically connect to a second gas delivery component of the CPAP system to deliver a pressurized flow of breathable gas to a patient's airways. The gas delivery component includes a lumen forming a first part of a gas flow path for the breathable gas. A connection end of the gas delivery component is configured to engage the second gas delivery component. In addition, a magnetic connection assembly is located at the connection end and includes a magnet positioned at least partially within the lumen. The magnetic connection assembly is configured to magnetically secure the gas delivery component to the second gas delivery component.
