Abstract

Claims (25)

1. A method of securing a nasal interface of a ventilation system to a patient, the method comprising:

providing a left cannula of the nasal interface and a right cannula of the nasal interface connected to each other by an adjustable inter-connector that allows pivoting of respective distal ends of the left and right cannulas;

providing tubing coupled to respective proximal ends of the left and right cannulas, the tubing including a ventilator gas delivery channel and a pressure tap conduit;

adjusting the adjustable inter-connector to align the distal ends of the left and right cannulas with left and right nostrils of the patient; and

extending the tubing around left and right ears of the patient to secure the nasal interface to the patient;

wherein the nasal interface further comprises, for each of the left and right cannulas, a nozzle arranged to deliver ventilation gas from the tubing to the cannula.

2. The method of claim 1 , wherein the tubing has an outer diameter of 3 to 7 millimeters.

3. The method of claim 2 , wherein the tubing has an outer diameter of 4 to 6 millimeters.

4. The method of claim 1 , wherein each of the left and right cannulas has a tubular extension configured to impinge with the respective left and right nostrils of the patient.

5. The method of claim 4 , wherein the tubular extensions comprise nasal pillows.

6. The method of claim 1 , wherein the left and right cannulas are curved.

7. The method of claim 1 , wherein each of the left and right cannulas comprises an aperture through which ambient air may be entrained by the ventilation gas exiting the nozzle.

8. A method of administering ventilation therapy to a patient via a nasal interface of a ventilation system, the method comprising:

providing a left cannula of the nasal interface and a right cannula of the nasal interface connected to each other by an adjustable inter-connector that allows pivoting of respective distal ends of the left and right cannulas;

providing tubing coupled to respective proximal ends of the left and right cannulas, the tubing including a ventilator gas delivery channel and a pressure tap conduit;

adjusting the adjustable inter-connector to align the distal ends of the left and right cannulas with left and right nostrils of the patient;

extending the tubing around left and right ears of the patient to secure the nasal interface to the patient; and

delivering ventilation gas to the patient via the ventilator gas delivery channel of the tubing and the left and right cannulas of the nasal interface;

wherein the nasal interface further comprises, for each of the left and right cannulas, a nozzle arranged to deliver the ventilation gas from the tubing to the cannula.

9. The method of claim 8 , wherein said delivering ventilation gas is performed while the nasal interface is secured to the patient only by the tubing.

10. The method of claim 8 , wherein the tubing has an outer diameter of 3 to 7 millimeters.

11. The method of claim 10 , wherein the tubing has an outer diameter of 4 to 6 millimeters.

12. The method of claim 8 , wherein each of the left and right cannulas has a tubular extension configured to impinge with the respective left and right nostrils of the patient.

13. The method of claim 12 , wherein the tubular extensions comprise nasal pillows.

14. The method of claim 8 wherein each of the left and right cannulas comprises an aperture through which ambient air may be entrained by the ventilation gas exiting the nozzle.
