Abstract

An apparatus for providing pressure into which a patient must exhale is provided. The canister has a canister axis and is disposed to hold liquid. The canister also has indicia of pressure on the canister. The apparatus also includes a substantially rigid lid disposed to substantially cover a mouth of the canister and having a first inlet through the lid. The apparatus also includes an adapter in the first inlet. The apparatus also includes a conduit being retained by the adapter such that the conduit is substantially immovable relative to the canister axis.

Claims

1. An apparatus for providing pressure into which a patient must exhale, the apparatus comprising:

a canister having a canister axis and being disposed to hold liquid, the canister having indicia of pressure on the canister;

a substantially rigid lid disposed to substantially cover a mouth of the canister and having a first inlet through the lid;

an adapter in the first inlet; and

a conduit being retained by the adapter such that the conduit is substantially immovable relative to the canister axis.

2. The apparatus of claim 1, wherein the conduit is substantially immovable relative to the canister axis such that a first end of the conduit is maintained at a substantially same indicia of pressure before and while the apparatus is in use.

3. The apparatus of claim 1, wherein the apparatus is in use when the liquid and an exhaled gas are received in the conduit.

4. The apparatus of claim 1, wherein the indicia of the pressure comprises values in a descending order from a top portion of the canister to a bottom portion of the canister.

5. The apparatus of claim 1, wherein the first end of the conduit is positioned at a value of the indicia of the pressure corresponding to approximately zero cm H₂O pressure.

6. The apparatus of claim 1, wherein the conduit is a corrugated tube.

7. The apparatus of claim 1, wherein the adapter has one or more recesses for coupling to a second end of the conduit.

8. The apparatus of claim 1, wherein the adapter is dimensioned to telescopically couple to the second end of the conduit.

9. The apparatus of claim 1, further comprising an air filter inlet in one of the lid or the canister and disposed to couple to an air filter.

10. The apparatus of claim 9, further comprising an air filter coupled in the air filter inlet.

11. The apparatus of claim 1, further comprising a liquid adjustment subsystem, the liquid level adjustment subsystem comprising:

a fluid flow mechanism coupleable to a bottom portion of the canister; and

a syringe operatively coupleable to the fluid flow mechanism and being disposed to adjust a level of liquid in the canister or provide a volume of the liquid to the canister.

12. The apparatus of claim 1, further comprising a pressure gauge coupled to one of the lid or the canister.

13. The apparatus of claim 12, wherein the pressure gauge is a disposable pressure gauge.

14. The apparatus of claim 1, further comprising a bracket coupled to one of the lid or the canister and disposed to receive a support mechanism.

15. The apparatus of claim 14, wherein the bracket is adapted to swivel.

16. The apparatus of claim 14, wherein the support mechanism has an orientation that is substantially perpendicular to the canister axis.

17. The apparatus of claim 14, wherein the support mechanism has an orientation that is substantially parallel to the canister axis.

18. A bubble nasal continuous positive airway pressure system comprising:

a pressure device having a canister with a canister axis, disposed to hold liquid and having indicia of pressure on the canister, the pressure device also having a substantially rigid lid and a substantially immovable conduit, the pressure device being disposed to provide a substantially steady pressure while the pressure device is in use;

an expiratory tube having a first end coupled to the pressure device and having a second end coupled to a first end of a respiratory breathing aid of the system; and

an inspiratory tube having a first end coupled to a gas source of the system and having a second end coupled to a second end of the respiratory breathing aid.

19. The system of claim 18, wherein the pressure device is in use when the liquid and an exhaled gas are received in the conduit.

20. An apparatus for providing pressure into which a patient must exhale, the apparatus comprising:

a canister having a canister axis and being disposed to hold liquid, the canister having indicia of pressure on the canister, the canister also having a first inlet through the canister;

an adapter in the first inlet; and

a conduit being retained by the adapter such that the conduit is substantially immovable relative to the canister axis when the apparatus is in use.
