PAP system

A positive airway pressure (PAP) system adapted for treatment of respiratory disease or sleep disordered breathing comprising:

• a headgear adapted for engaging a patient's head;
• a patient interface adapted to be secured to and sealed against a portion of the patient's face, in use, by the headgear;
• and
• a flow generator adapted to be connected to the patient interface, and wherein the flow generator is adapted to be secured by a portion of the headgear to the patient's head,
• wherein the flow generator comprises a blower adapted to provide pressurised breathable gas to a patient through the patient interface and the blower is at least partially vibrationally isolated from the patient's head by at least one dampening means adapted to reduce the amount of transmitted vibration received by the patient, the at least one dampening means comprising at least one foam layer mounted within the flow generator to secure the blower,
• wherein the flow generator comprises a mounting structure limiting an extent of a compression of the at least one foam layer due to the weight of the blower, the mounting structure including at least one protrusion extending from an interior surface of the flow generator toward the blower, and
• wherein the at least one protrusion is more rigid than the at least one foam layer.

• a blower adapted to provide pressurised breathable gas to a patient through the patient interface;
• compressible foam configured to a) support the blower and b) dampen and/or reduce vibration generated by the blower such that the blower is at least partially vibrationally isolated from the patient's head by the compressible foam;
• and
• at least one protrusion extending from an interior surface of the flow generator toward the blower to support the blower, the at least one protrusion being positioned to limit an extent of compression of the compressible foam due to the weight of the blower, wherein the at least one protrusion is more rigid than the compressible foam.
