Abstract

A wye connector has a patient coupling end. The patient coupling end has a first connector surface and a second connector surface. The first connector surface has a first diameter at an axial location along the patient coupling end. The second connector surface has a second diameter at the same axial location along the patient coupling end. The first diameter is larger than the second diameter. The second connector surface projects axially outward beyond the first connector surface.

First claim

What is claimed is:

1. A wye connector comprising a patient coupling end, the patient coupling end having a first connector surface and a second connector surface, the first connector surface having a first diameter at an axial location along the patient coupling end, the second connector surface having a second diameter at the same axial location along the patient coupling end, the first diameter being larger than the second diameter, and at least a portion of the second connector surface projecting axially outward beyond the first connector surface,
wherein the first connector surface is formed on a first connector portion configured to connect to a first connector at the patient coupling end and the second connector surface is formed on a second connector portion configured to connect to a second connector at the patient coupling end, the first connector being a different type of connector than the second connector.

2. The wye connector of claim 1 , wherein the first connector portion and the second connector portion are separated by a gap.

3. The wye connector of claim 2 , wherein the first connector surface terminates proximally of a distal end of the gap.

4. The wye connector of claim 2 , wherein the gap is isolated from flow through the patient coupling end of the wye connector.

5. The wye connector of claim 1 , wherein the first connector surface comprises a male taper connector and the second connector surface comprises a female taper connector.

6. The wye connector of claim 5 , wherein the male taper connector is a 22 mm male taper connector and the female taper connector is a 15 mm female taper connector.

7. The wye connector of claim 1 , further comprising an inspiratory connector end and an expiratory connector end, the inspiratory connector end defining at least a portion of an inspiratory branch and the expiratory connector end defining at least a portion of an expiratory branch.

8. The wye connector of claim 7 , wherein the inspiratory connector end defines an inspiratory flow lumen having an inspiratory flow lumen axis and the expiratory connector end defines an expiratory flow lumen having an expiratory flow lumen axis, the inspiratory flow lumen axis and the expiratory flow lumen axis extending generally parallel to each other.

9. The wye connector of claim 7 , further comprising a probe port positioned between the inspiratory connector end and the patient coupling end.

10. The wye connector of claim 9 , wherein the probe port is positioned along the inspiratory branch.

11. The wye connector of claim 7 , further comprising an introduction port positioned between the inspiratory connector end and the patient coupling end.

12. The wye connector of claim 11 , wherein the introduction port is positioned between the inspiratory branch and the expiratory branch.

13. The wye connector of claim 1 , wherein a first distance from a proximal-most end of the second connector surface to a proximal-most end of the first connector surface is between about 0.1 mm and about 8 mm.

14. The wye connector of claim 13 , wherein the first distance is between about 0.1 mm and about 2 mm.

15. The wye connector of claim 14 , wherein the first distance is about 0.13 mm.

16. The wye connector of claim 3 , wherein a second distance from a distal-most end of the first connector surface to a distal-most end of the gap is between about 0.5 mm and about 15 mm.

17. The wye connector of claim 16 , wherein the second distance is between about 1 mm and about 5 mm.

18. The wye connector of claim 17 , wherein the second distance is about 3.6 mm.

19. The wye connector of claim 7 , wherein the inspiratory connector end defines an inspiratory flow lumen having an inspiratory flow lumen axis and the expiratory connector end defines an expiratory flow lumen having an expiratory flow lumen axis, the inspiratory flow lumen axis and the expiratory flow lumen axis separated from each other by an angle greater than 0 degrees and less than 90 degrees.

20. The wye connector of claim 19 , wherein the angle is between about 2 degrees and about 30 degrees.

21. The wye connector of claim 20 , wherein the angle is about 14 degrees.

22. The wye connector of claim 2 , wherein the first connector surface comprises a male taper connector and the second connector surface comprises a female taper connector.
