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, 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;

a conduit fixed to the first end of the adapter such that the conduit is substantially immovable relative to the canister axis;

a connector having a first end coupled to a second end of the adapter, wherein the connector and the second end of the adapter are coupled such that a channel is formed between the conduit and the connector; and

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 at least one of adjust a level of liquid in the canister or provide a volume of the liquid to the canister.

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 an exhaled gas is 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, wherein the top portion of the canister corresponds to a portion of the canister proximate to the mouth 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 H₂0 pressure.

6. The apparatus of claim 1, wherein a second end of the conduit is fixed within one or more recesses proximate to the first end of the adapter.

7. The apparatus of claim 1, wherein a second end of the conduit is telescopically fixed to the first end of the adapter.

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

9. The apparatus of claim 8, further comprising the air filter coupled in the air filter inlet.

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

11. The apparatus of claim 10, wherein the pressure gauge is a disposable pressure gauge.

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

13. The apparatus of claim 12, wherein the bracket is adapted to swivel.

14. The apparatus of claim 12, wherein the support mechanism has an orientation that is substantially perpendicular to the canister axis.

15. The apparatus of claim 12, wherein the support mechanism has an orientation that is substantially parallel to the canister axis.

16. The apparatus of claim 1, wherein the connector is telescopically coupled to the adapter.

17. The apparatus of claim 1, wherein the apparatus is a bubble nasal continuous positive airway pressure apparatus.

18. A bubble nasal continuous positive airway pressure system

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;

a conduit being fixed to a first end of the adapter such that the conduit is substantially immovable relative to the canister axis;

a connector having a first end coupled to a second end of the adapter, wherein the connector and the second end of the adapter are coupled such that a channel is formed between the conduit and the connector; and

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 at least one of adjust a level of liquid in the canister or provide a volume of the liquid to the canister;

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 an exhaled gas is received in the conduit.

20. An 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 fixed to a first end of the adapter such that the conduit is substantially immovable relative to the canister axis;

a connector having a first end coupled to a second end of the adapter, wherein the connector and the second end of the adapter are coupled such that a channel is formed between the conduit and the connector; and

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 at least one of adjust a level of liquid in the canister or provide a volume of the liquid to the canister.
