Abstract

An adjustable airway pressure system is provided. The system may include a cap and a canister. The cap may include a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and adapted to receive and output exhaled gas. The conduit may have screw threads on an exterior surface of the conduit. The cap may also include an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads. The second plurality of screw threads may couple and be complementary to the first plurality of screw threads such that a rotation of the adjust collar causes the conduit to move in a substantially vertical direction. The conduit may be adapted to be adjusted to heights along a continuum. The canister may contain liquid and receive the conduit such that the received exhaled gas is output from the conduit into the liquid.

Claims

1. An adjustable airway pressure system comprising:

a cap including;

a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and being adapted to receive and output exhaled gas, the conduit also having a first plurality of screw threads on an exterior surface of the conduit; and

an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads, the second plurality of screw threads coupling and being complementary to the first plurality of screw threads such that a rotation of the adjust collar causes the conduit to move in a substantially vertical direction, the conduit adapted to be adjusted to one of a plurality of heights along a continuum from a first height corresponding to a maximum value of the plurality of airway pressure values to a second height corresponding to a minimum value of the plurality of airway pressure values;

an adjust knob circumscribing and coupled to the adjust collar such that the adjust collar is rotated upon rotation of the adjust knob;

a cap retainer;

a canister connector; and

a bracket, the cap retainer retaining the conduit and coupling the canister connector and the bracket; and

a canister containing liquid and receiving the conduit such that the received exhaled gas is output from the conduit into the liquid.

2. The adjustable airway pressure system of claim 1, wherein the canister is a pre-filled bottle of water.

3. The adjustable airway pressure system of claim 1, wherein the bracket is in fluid communication with the cap retainer, and the cap retainer includes a first plurality of apertures adapted to emit a volume of the exhaled gas from the canister to the bracket, and the bracket includes a second plurality of apertures adapted to emit the volume of the exhaled gas from the adjustable airway pressure system.

4. The adjustable airway pressure system of claim 1, wherein the cap further comprises a lock nut having a third plurality of screw ridges coupling and complementary to the first plurality of screw threads of the conduit such that a rotation of the lock nut moves the lock nut in a substantially vertical direction along the conduit.

5. The adjustable airway pressure system of claim 4, wherein the lock nut is adapted to fix the adjust knob in a selected position to substantially prevent movement of the conduit.

6. An adjustable airway pressure system cap comprising:

a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and being adapted to receive and output exhaled gas, the conduit also having a first plurality of screw threads on an exterior surface of the conduit; and

an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads, the second plurality of screw threads coupling and being complementary to the first plurality of screw threads such that a rotation of the adjust collar causes the conduit to move in a substantially vertical direction, the conduit adapted to be adjusted to one of a plurality of heights along a continuum from a first height corresponding to a maximum value of the plurality of airway pressure values to a second height corresponding to a minimum value of the plurality of airway pressure values;

an adjust knob circumscribing and coupled to the adjust collar such that the adjust collar is rotated upon rotation of the adjust knob;

a cap retainer;

a canister connector; and

a bracket, the cap retainer retaining the conduit and coupling the canister connector and the bracket.

7. The adjustable airway pressure system cap of claim 6, wherein the bracket is in fluid communication with the cap retainer, and the cap retainer includes a first plurality of apertures adapted to emit a volume of the exhaled gas to the bracket, and the bracket includes a second plurality of apertures adapted to emit the volume of the exhaled gas from the adjustable airway pressure system cap.

8. The adjustable airway pressure system cap of claim 7, further comprising a lock nut having a third plurality of screw ridges coupling and complementary to the first plurality of screw threads of the conduit such that a rotation of the lock nut moves the lock nut in a substantially vertical direction along the conduit.

9. The adjustable airway pressure system cap of claim 8, wherein the lock nut is adapted to fix the adjust knob in a selected position to substantially prevent movement of the conduit.

10. The adjustable airway pressure system cap of claim 7, wherein the bracket is adapted to couple to a swivelable clamp for coupling the adjustable airway pressure system cap to a support structure.

11. The adjustable airway pressure system cap of claim 6, further comprising an expiratory tube port adapted to couple to an expiratory tube in a bubble nasal continuous airway pressure system.

12. A bubble nasal continuous airway pressure system comprising:

a gas source adapted to output inspiratory gas;

an inspiratory tube adapted to receive the inspiratory gas and provide it to a patient;

an expiratory tube adapted to receive the exhaled gas from the patient; and

an adjustable airway pressure system having;

a cap including;

a head coupled to an expiratory tube port for coupling to an expiratory tube and receiving exhaled gas;

a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and being adapted to receive and output the exhaled gas from the head, the conduit also having a first plurality of screw threads on an exterior surface of the conduit; and

an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads, the second plurality of screw threads coupling and being complementary to the first plurality of screw threads such that a rotation of the adjust collar causes the conduit to move in a substantially vertical direction, the conduit adapted to be adjusted to one of a plurality of heights along a continuum from a first height corresponding to a maximum value of the plurality of airway pressure values to a second height corresponding to a minimum value of the plurality of airway pressure values;

an adjust knob circumscribing and coupled to the adjust collar such that the adjust collar is rotated upon rotation of the adjust knob;

a cap retainer;

a canister connector; and

a bracket, the cap retainer retaining the conduit and coupling the canister connector and the bracket; and

a canister containing liquid and receiving the conduit such that the received exhaled gas is output from the conduit into the liquid, thereby providing an airway pressure to the patient.
