Abstract

A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.

First claim

What is claimed is:

1. A PAP system, comprising:
a PAP device to generate a supply of pressurized air;
a patient interface adapted to form a seal with a patient's face;
air delivery tubing to interconnect the patient interface and the PAP device; and
a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing,
wherein the cover includes a wrap or scarf-like arrangement including a headgear strap portion that cooperates with another headgear strap adapted to wrap entirely around a patient's head to stabilize and support the system on the patient's head,
wherein the PAP device is supported within the cover such that the PAP device is suspendible from the patient's head by the air delivery tubing, and
wherein the cover includes a tube portion to substantially enclose one or more portions of the air delivery tubing and a pouch portion to substantially enclose one or more portions of the PAP device, and at least a portion of the pouch portion comprises a diffuse material structured and arranged to allow air therethrough to an air inlet of the PAP device to allow operation of the PAP device when enclosed by the pouch portion.

2. The PAP system according to claim 1 , wherein the cover substantially encloses one or more portions of the patient interface.

3. The PAP system according to claim 1 , wherein the PAP device generates a supply of pressurized air in the range of about 2-30 cm H 2 O.

4. The PAP system according to claim 1 , wherein the patient interface includes a nozzle, nasal prong, pillow, cradle or cushion arrangement.

5. The PAP system according to claim 1 , wherein the air delivery tubing includes a non-cylindrical cross-sectional shape structured such that the air delivery tubing may move between a first open phase and a second at least partially collapsed phase.

6. The PAP system according to claim 1 , wherein the cover is constructed of a textile material.

7. The PAP system according to claim 1 , wherein the patient interface, air delivery tubing, cover, and/or headgear strap is constructed of materials including different colors, patterns, and/or surface texture so as to blend in with the patient's skin and/or hair.

8. The PAP system according to claim 1 , wherein the cover is structured to hide, veil or conceal one or more connection points between the PAP device, patient interface, and air delivery tubing.

9. The PAP system according to claim 1 , wherein the PAP device is adapted to be located over the patient's shoulder when the patient is in an upright position and/or adapted to be located beside, near or adjacent the patient when the patient is in a supine position.

10. The PAP system according to claim 9 , wherein the PAP device is adapted to be located near the patient's chest when the patient is in the supine position.

11. The PAP system according to claim 1 , wherein the system is portable and lightweight to allow the patient to freely move around while wearing the system.

12. The PAP system according to claim 1 , wherein the headgear strap portion and the headgear strap are structured to overlap by the patient's nose.

13. The PAP system according to claim 12 , wherein the headgear strap portion and the headgear strap are connected to one another at the overlap.

14. The PAP system according to claim 1 , wherein the PAP device is adapted to be positioned relatively close to the patient's nose to provide the air delivery tubing with a reduced tube diameter.

15. The PAP system according to claim 14 , wherein the PAP device is adapted to be positioned about 50 cm to 80 cm from the patient's nose resulting in the air delivery tubing having a tube diameter of about 10 mm to 20 mm.

16. The PAP system according to claim 1 , wherein the system is reversible which allows the air delivery tubing to extend from either side of the patient interface.

17. The PAP system according to claim 1 , wherein the system is configured to wrap across to either the left side or the right side of the patient's body or face.

18. The PAP system according to claim 1 , wherein the system defines a loop adapted to pass generally along an underside of the patient's nose, along the cheek regions, above the ears, and over the crown and parietal portion of the patient's head.

19. The PAP system according to claim 1 , wherein the headgear strap portion is adapted to wrap along the cheek region, above the ear, and around the back of the patient's head, and connect to an intermediate portion of the headgear strap so as to define a back strap for supporting the system.

20. The PAP system according to claim 1 , wherein the headgear strap is adapted to wrap under the patient's nose, along the cheek region, above the ear, and over the crown of the patient's head, and connect to an intermediate portion of the headgear strap portion to as to define a crown strap for supporting the system.

21. The PAP system according to claim 1 , wherein at least a portion of the PAP device extends out of the cover to allow access to one or more controls provided to the PAP device.

22. The PAP system according to claim 1 , wherein the headgear strap portion and the headgear strap are structured to overlap by the patient's nose, the headgear strap portion and the headgear strap are connected to one another at the overlap by a connector, and the connector provides a vent from the patient interface.

23. The PAP system according to claim 22 , wherein the connector comprises a button.

24. The PAP system according to claim 1 , wherein the diffuse material of the pouch portion allows the air inlet of the PAP device to communicate with atmosphere.

25. The PAP system according to claim 24 , wherein the cover is structured and arranged to create a gap adjacent the air inlet of the PAP device to prevent occlusion of the air inlet of the PAP device in use.

26. The PAP system according to claim 1 , wherein the diffuse material of the pouch portion covers the air inlet and allows air to pass through a thickness of the pouch portion to the air inlet of the PAP device.

27. The PAP system according to claim 1 , wherein said portion of the pouch portion comprises an opening adjacent the air inlet of the PAP device.

28. A system for delivery of pressurized air to a patient for therapy, the system comprising:
a base unit including a blower configured to generate a supply of air at positive pressure;
a patient interface adapted to be provided to a patient's face;
a tube to deliver the supply of air at positive pressure from the base unit to the patient interface; and
a controller configured to monitor and automatically control adjustment of the system so that the patient interface is automatically positioned optimally for the patient for therapy,
wherein the controller is configured to (1) receive one or more of data from a force sensor, data regarding the positioning of the tube, data regarding the patient's sleeping position, and data regarding the patient's breathing patterns in order to analyse the patient's activity and positioning, and based on said data, (2) automatically modify a shape of the tube in order to move the patient interface to achieve satisfactory seal and comfort for optimal treatment, and wherein the system is adapted to adjust the total force applied to the patient's face by the patient interface in response to leak or patient discomfort.
