Abstract

A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system in a high flow therapy system, the gas delivery conduit includes a first connector adapted for connecting to the respiratory gases delivery system, a second connector adapted for connecting to a fitting of a patient interface, tubing fluidly connecting the first connector to the second connector where the first connector has a gas inlet adapted to receive the supplied respiratory gas, one of electrical contacts and temperature contacts integrated into the first connector. The gas delivery conduit further can include a sensing conduit integrated into the gas delivery conduit, where the first connector of the gas delivery conduit is adapted to allow the user to couple the first connector with the respiratory gases delivery system in a single motion.

First claim

What is claimed is:

1. A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system, the gas delivery conduit comprising:
a first connector adapted for connecting to the respiratory gases delivery system;
a second connector adapted for connecting to a fitting of a patient interface; and
tubing fluidly connecting the first connector to the second connector;
wherein the first connector includes:
a gas lumen adapted to receive the respiratory gas and pass the respiratory gas through the tubing; and
a pressure conduit adapted for engagement with a pressure port, the pressure conduit including an inlet portion and an outlet portion,
wherein the first connector includes contacts comprising external connector contacts disposed on the first connector, wherein the contacts of the first connector comprise at least one of an electrical contact and temperature contacts, and
wherein the external connector contacts are adapted to be engaged with respiratory gases delivery system contacts of the respiratory gases delivery system,
wherein the first connector comprises a flange for engaging with a receptable of the respiratory gases delivery system and configured to orient the first connector relative to the respiratory gases delivery system to facilitate alignment of at least the external connector contacts with the respiratory gases delivery system contacts, the flange further comprising a planar surface for aligning the pressure conduit for engagement with the pressure port of the respiratory gases delivery system.

2. The gas delivery conduit of claim 1 , wherein the pressure conduit comprises a sensing conduit.

3. The gas delivery conduit of claim 2 , wherein the sensing conduit is adapted to facilitate monitoring one of pressure, pulse oximetry, carbon dioxide and oxygen.

4. The gas delivery conduit of claim 2 , wherein the sensing conduit is configured to couple with a port of the respiratory gases delivery system.

5. The gas delivery conduit of claim 1 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system in a single motion.

6. The gas delivery conduit of claim 1 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system by moving the first connector in a direction along an axis of the gas lumen.

7. The gas delivery conduit of claim 1 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system in a predetermined orientation.

8. The gas delivery conduit of claim 1 , further comprising at least one temperature sensor.

9. The gas delivery conduit of claim 1 , further comprising a heating element.

10. The gas delivery conduit of claim 1 , wherein the external connector contacts are adapted to couple with system electrical contacts of the respiratory gases delivery system.

11. The gas delivery conduit of claim 1 , wherein the electrical contacts are adapted to facilitate providing power to the gas delivery conduit.

12. The gas delivery conduit of claim 1 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system by moving the first connector in a single direction.

13. The gas delivery conduit of claim 1 , wherein the first connector is adapted to couple with a gas outlet of the respiratory gases delivery system and a receptacle of the respiratory gases delivery system.

14. The gas delivery conduit of claim 1 , wherein inlet portion is coaxially disposed with the gas lumen, and an outlet portion is coaxially disposed with the pressure port.

15. A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system, the gas delivery conduit comprising:
a first connector adapted for connecting to the respiratory gases delivery system;
a second connector adapted for connecting to a fitting of a patient interface; and
tubing fluidly connecting the first connector to the second connector;
wherein the first connector includes:
a gas lumen adapted to receive the respiratory gas and pass the respiratory gas through the tubing, and
a pressure conduit adapted for engagement with a pressure port, the pressure conduit including an inlet portion that is coaxially disposed with the gas lumen
wherein the first connector comprises a flange for engaging with a receptable of the respiratory gases delivery system and configured to orient the first connector relative to the respiratory gases delivery system, the flange comprising a planar surface configured to align the pressure conduit for engagement with the pressure port of the respiratory gases delivery system.

16. The gas delivery conduit of claim 15 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system in a predetermined orientation.

17. The gas delivery conduit of claim 15 , wherein the first connector is adapted to allow a user to couple the first connector with the respiratory gases delivery system by moving the first connector in a single direction.

18. The gas delivery conduit of claim 15 , wherein the pressure conduit further includes an outlet portion that is coaxially disposed with the pressure port.

19. A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system, the gas delivery conduit comprising:
a first connector adapted for connecting to the respiratory gases delivery system;
a second connector adapted for connecting to a fitting of a patient interface; and
tubing fluidly connecting the first connector to the second connector;
wherein the first connector includes:
a gas lumen adapted to receive the respiratory gas and pass the respiratory gas through the tubing; and
a pressure conduit adapted for engagement with a pressure port, the pressure conduit including an outlet portion that is coaxially disposed with the pressure port,
wherein the first connector comprises a flange for engaging with a receptable of the respiratory gases delivery system and configured to orient the first connector relative to the respiratory gases delivery system, the flange further comprising a planar surface configured to align the pressure conduit for engagement with the pressure port of the respiratory gases delivery system.

20. The gas delivery conduit of claim 19 , wherein the first connector is adapted for coupling with the respiratory gases delivery system though movement of the first connector in a single direction.

21. The gas delivery conduit of claim 19 , wherein the pressure conduit further includes an inlet portion that is coaxially disposed with the gas lumen and the inlet portion is within the gas lumen.
