Abstract

The systems and methods described herein include a small system integrated within a tubing for providing positive air pressure to a patient. The system may include a tube with an inlet opening, an expansion section with a gas flow generator, and an outlet opening. The systems and methods described herein provide improved mobility, comfort, and usability for patients.

Claims

1. A CPAP system comprising:

a tube having at least one expansion section; and

a gas flow generator disposed in a portion of the expansion section, wherein the gas flow generator comprises a motor to drive an impellor whereby a positive air pressure and flow are generated.

2. The system of claim 1, further comprising a coupling device along a downstream portion of the tube from the expansion section that detachably couples with a mask.

3. The system of claim 1, further comprising a display screen on a portion of the external surface of the expansion section of the tube.

4. The system of claim 1, wherein a power supply cord runs along the length of an upstream portion of the tube to the expansion section.

5. The system of claim 1, wherein the expansion section is an acoustic reduction chamber.

6. The system of claim 1, further comprising a second expansion section, configured to function as an acoustic reduction chamber.

7. The system of claim 6, further including noise deflectors placed within the second expansion section.

8. The system of claim 6, wherein noise reduction attenuating material is placed within the second expansion section.

9. The system of claim 6, wherein a portion of the electronics driving the motor are placed within the second expansion section.

10. The system of claim 1, wherein the blower is configured to produce pressures ranging from 2-40 cm H₂O.

11. The system of claim 1, wherein the tube is comprised of a plurality of detachable sections.

12. The system of claim 1, further comprising at least one of a circuit board, sensor, or power supply component disposed within the expansion section.

13. The system of claim 1, wherein electronic circuitry, processors or other electronic components are disposed outside of the tube.

14. The system of claim 12, wherein an electrical communication and power source connects the external electronic circuitry, processes, or electronic components with the blower.

15. The system of claim 12, wherein the electric circuitry, processors or other electronic components and/or the power supply and/or battery are attached to the mask or to a user.

16. An elongated CPAP system comprising:

a tube having an inlet port, an outlet, and an expansion section, and wherein the expansion section is positioned between the inlet port and the outlet; and

a gas flow generator positioned in the expansion section, wherein the gas flow generator generates positive gas pressure and flow through the outlet.

17. The system of claim 16, further comprising at least detachable attenuating noise tube section, configured to reduce the noise attenuated from the system.

18. The attenuating noise tube section of claim 17, further including an inlet that expands into a larger volume disposed within the attenuating noise tube section.

19. The attenuating noise tube section of claim 17, further including circuitous flow path within the attenuating noise tube section.

20. The system of claim 16, further comprising a separated user interface that remotely communicates with the blower.

21. The system of claim 16, further including at least one sensor for detecting flow rates connected to a flow port that is disposed downstream from the blower.

22. A portable and elongated CPAP system comprising:

an expansion tube section having a blower comprised of a motor and impellor disposed therein;

at least two detachable tube sections for attaching to an inlet and outlet port of the expansion tube section, wherein one of the detachable tube sections has acoustically designed inlet port that forms a low pass frequency filter with an expansion chamber disposed in the expansion tube section.
