A connector includes a mask end for connecting with the interior of a respiratory mask, a supply conduit end, and a gas washout vent passage having an inlet adjacent to, or forming part of, the mask end in fluid communication with the interior of the respiratory mask and an outlet in fluid communication with atmosphere. The vent outlet of the vent passage is disposed on the side of the connector remote from the mask end. A respiratory mask includes a mask shell, a mask inlet for connecting with the outlet of a breathable gas supply conduit, and a gas washout vent passage. A vent outlet is disposed on the side of the mask remote from the mask interior and is adapted to direct the washout gas in a direction substantially parallel to the longitudinal axis of the mask inlet and away from the mask inlet.

We claim: 1. A connector comprising: a mask end adapted to communicate with an interior of a respiratory mask; a supply conduit end disposed at an angle to the mask end and adapted to communicate with an outlet of a breathable gas supply conduit; a gas washout vent passage having a vent inlet in fluid communication with the interior of the respiratory mask and a vent outlet in fluid communication with the atmosphere, the vent outlet is disposed on a side of the connector remote from the mask end; a body portion; and a cap portion detachably connected to the body portion, the cap portion and body portion defining the vent passage therebetween, wherein the vent inlet is formed in the body portion adjacent to, and downstream of, the mask end relative to the washout gas flow and is in fluid communication with the mask interior via the body portion; and wherein the vent passage extends along an arc from the vent inlet to the vent outlet. 2. The connector as claimed in claim 1, wherein the supply conduit end is substantially perpendicular to the mask end. 3. The connector as claimed in claim 1, wherein the supply conduit end is angled at approximately 135 degrees to the mask end. 4. The connector as claimed in claim 1, wherein the cap portion and body portion are rigid and fixed relative to each other when attached. 5. The connector as claimed in claim 1, wherein the body portion includes grooves or ridges adapted to engage ridges or grooves respectively on the cap portion to attach the cap portion to the body portion. 6. The connector as claimed in claim 1, wherein one of the body portion and the cap portion includes a spacer extending between said cap portion and said body portion. 7. The connector as claimed in claim 1, wherein the vent outlet is oriented to guide washout gas in a direction substantially parallel to and along an extended surface portion downstream of the vent outlet and open to atmosphere. 8. The connector as claimed in claim 1, wherein the vent outlet includes an interior surface that forms a smooth prolongation with an adjacent exterior surface of the body portion. 9. The connector as claimed in claim 8, wherein the smooth prolongation allows exhaled gas to vent along a continuous surface open to atmosphere. 10. The connector as claimed in claim 1, wherein the vent outlet is in fluid communication with atmosphere for gas washout to atmosphere in the immediate vicinity of the vent outlet. 11. The connector as claimed in claim 1, wherein the vent passage provides fluid communication between the interior of the mask and immediate atmosphere. 12. The connector as claimed in claim 1, wherein the vent passage is open in use at least during the inhalation and exhalation phases of the user's breathing cycle. 13. The connector as claimed in claim 1, wherein the vent outlet is generally semi-circular when viewed in cross-section. 14. A respiratory mask comprising: a mask shell defining an interior of the respiratory mask; a mask inlet adapted to communicate with an outlet of a breathable gas supply conduit; and a gas washout vent passage having a vent inlet in fluid communication with the interior of the respiratory mask and a vent outlet in fluid communication with atmosphere, the vent outlet is disposed on a side of the mask remote from the mask interior and is adapted to direct washout gas in a direction substantially parallel to a longitudinal axis of the mask inlet and away from the mask inlet, wherein the mask shell includes a body portion and a cap portion that define the vent passage therebetween, and the vent passage comprises an inlet portion of relatively large cross-sectional area adjacent the vent inlet and an outlet portion of relatively small cross-sectional area adjacent the vent outlet. 15. The mask as claimed in claim 14, wherein the cap portion is detachable from the body portion. 16. The mask as claimed in claim 15, wherein the cap portion and body portion are rigid and fixed relative to each other when attached. 17. The mask as claimed in claim 14, wherein the body portion includes grooves or ridges adapted to engage ridges or grooves respectively on the cap portion to attach the cap portion to the body portion. 18. The mask as claimed in claim 14, wherein one of the body portion or cap portion includes a spacer extending between the cap portion and the body portion. 19. The mask as claimed in claim 14, wherein the vent passage comprises a relatively long inlet portion of constant cross-section, a relatively long outlet portion of constant cross-section and a transition portion of smoothly reducing cross-section extending from the inlet portion to the outlet portion. 20. The mask as claimed in claim 14, when the vent passage substantially follows the shape of the body portion. 21. The respiratory mask as claimed in claim 14, wherein the vent outlet is oriented to guide washout gas along an extended surface portion downstream of the vent outlet and open to atmosphere. 22. The respiratory mask as claimed in claim 14, wherein the vent outlet includes an interior surface that forms a smooth prolongation with an adjacent exterior surface of the body portion. 23. The respiratory mask as claimed in claim 22, wherein the smooth prolongation allows exhaled gas to vent along a continuous surface open to atmosphere. 24. The respiratory mask as claimed in claim 14, wherein the vent outlet is in fluid communication with atmosphere for gas washout to atmosphere in the immediate vicinity of the vent outlet. 25. The respiratory mask as claimed in claim 14, wherein the vent passage provides fluid communication between the interior of the mask and immediate atmosphere. 26. The respiratory mask as claimed in claim 14, wherein the vent passage is open in use at least during the inhalation and exhalation phases of the user's breathing cycle. 27. A mask comprising: a mask shell defining an interior; a gas washout vent passage having an inlet in fluid communication with the interior and an outlet in fluid communication with atmosphere, wherein the outlet is oriented to guide washout gas in a direction substantially parallel to and along an extended surface portion downstream of the outlet; and a detachable cap portion defining at least a portion of the vent passage, wherein at least a portion of the vent passage is shaped and configured to allow gas to approach a generally laminar state, and the vent passage includes an inlet portion having a first cross-sectional area, an outlet portion having a second cross-sectional area that is smaller than the first cross-sectional area, and a transition portion of smoothly reducing cross-section extending between the inlet portion and the outlet portion. 28. The mask as claimed in claim 27, wherein at least a portion of the vent passage is defined by parallel surfaces to allow gas to approach a generally laminar state. 29. The mask as claimed in claim 27, wherein the outlet portion is relatively long to allow gas to approach a generally laminar state. 30. The mask as claimed in claim 27, wherein the transition portion is shaped and configured to substantially minimize introduction of any discontinuities into the gas flow. 31. The mask as claimed in claim 27, wherein the cap portion includes a rib to allow for adequate spacing and/or to maintain a cross-sectional area of the vent passage. 32. The mask as claimed in claim 27, wherein the outlet includes an interior surface that forms a smooth prolongation with an adjacent exterior surface of the body portion. 33. The mask as claimed in claim 32, wherein the smooth prolongation allows exhaled gas to vent along a continuous surface open to atmosphere. 34. The mask as claimed in claim 27, wherein the outlet is in fluid communication with atmosphere for gas washout to atmosphere in the immediate vicinity of the outlet. 35. The mask as claimed in claim 27, wherein the vent passage provides fluid communication between the interior of the mask shell and immediate atmosphere. 36. The mask as claimed in claim 27, wherein the vent passage is open in use at least during the inhalation and exhalation phases of the user's breathing cycle.
