Patent ID: 7931021

Claim:
A patient interface support for a Positive Airway Pressure (PAP) device, the device including a pressurized air source, a patient interface for supplying air to a patient's airflow passages and an air supply conduit for supplying pressurized air from the pressurized air source to said patient interface, said patient interface support comprising: a base for attachment to a support surface; a support extension including a first member and a second member, said first member having a joint for moveably connecting said support extension to said base at one end of said first member; said second member having a first end and a second end, said first end slidably coupled to an opposite end of said first member with a sliding connection along a longitudinal axis of the first member, the sliding connection being a piston and a cylinder, a track and ball or roller, or a sliding block and guide rail; a patient interface mount for mounting the patient interface at said second end of said second member; and biasing means in said support extension to apply a pre-selected engagement pressure at said patient interface to create a seal between said patient interface and the patient's airflow passages when said patient interface support is in use, wherein said seal between said patient interface and the patient's airflow passages is the only contact between the patient and said patient interface and the pre-selected engagement pressure being generated by coil springs, spiral or torsion springs, weights and pulleys, pneumatic or hydraulic elements, rubbers and elastomeric materials, linear and rotary motors, servomechanisms, hydraulic or pneumatic actuators, piezoelectric elements, or shape memory alloys.
