Abstract

Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient'"'"'s face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient'"'"'s body. The flow generator includes a blower (50) adapted to provide pressurized breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient'"'"'s body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient'"'"'s nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient'"'"'s head. A blower is structured to generate a supply of pressurized air. The blower is supported by the patient interface on the patient'"'"'s head and in communication with the patient interface. The headgear forms one or more ducts (42) to communicate pressurized air from the blower to a breathing cavity defined by the sealing arrangement.

Claims

1. A 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;

a flow generator adapted to be connected to the patient interface and adapted to be secured by a portion of the headgear to the patient'"'"'s head; and

a power supply connection adapted to connect the flow generator to a power supply to provide power to the flow generator,

wherein the flow generator comprises a blower, wherein the blower comprises an impeller and a motor adapted to drive the impeller to provide pressurised breathable gas to a patient through the patient interface and wherein EMF shielding is positioned between the motor and the patient'"'"'s head.

2. The PAP system according to claim 1, wherein the EMF shielding is mounted in parallel to the blower.

3. The PAP system according to claim 1, wherein the EMF shielding is planar.

4. The PAP system according to claim 1, wherein an upper surface area of the EMF shielding is substantially equal to or larger than lower surface area of the blower.

5. The PAP system according to claim 1, wherein the EMF shielding comprises metal shielding.

6. The PAP system according to claim 1, wherein the EMF shielding comprises a mesh.

7. The PAP system according to claim 1, wherein the EMF shielding is mounted within the flow generator.
