Abstract

Headgear (20) for securing a respiratory mask (12) to a patient incorporates a quick release arrangement. The headgear has at least one strap (22,24) extending from each side of the mask, the straps being releasably fastened rearwards of the patient'"'"'s face to secure the mask. The headgear further includes release means in the form of a pull cord (41) attached to an overlying strap (22) at its region of fastening to the underlying strap (24) an guided forward to be gripped at the front of patient. Pulling forward to the pull tab (45) of the cord (41) separates the fastening (28) between the straps (22,24) and pulls the mask away from the patient'"'"'s face.

Claims

1. A respiratory mask and headgear combination comprising a respiratory mask being a patient gas delivery mask having a first side and an opposite second side, and respiratory mask-securing headgear for securing said mask to the face of a wearer, the headgear including at least one strap extending from each of the first and second sides of the mask, the straps in use being releasably fastened at a region rearwards of the facial region of the wearer by fastening means so as to secure the mask, the headgear further including a release actuator acting on the fastening means and in use extending forward from the fastening means to a position substantially at the front of the wearer such that the release actuator may be gripped at substantially the front of the wearer and actuated to release the fastening means and thereby allow removal of the headgear from the wearer.

2. A respiratory mask and headgear combination according to claim 1 wherein the fastening means is located in use at the rear of the wearer'"'"'s head.

3. A respiratory mask and headgear combination according to claim 1 wherein the fastening means includes a hook fastener attached to one of said straps.

4. A respiratory mask and headgear combination according to claim 3 wherein the hook fastener releasably fastens to a covering of said other strap.

5. A respiratory mask and headgear combination according to claim 1 wherein an overlying one of said straps overlies the other of said straps at said fastening means, wherein said release actuator is attached to said overlying strap at said fastening means and acts to pull said overlying strap away from said other strap to release the fastening means.

6. A respiratory mask and headgear combination according to claim 5 wherein said fastening means includes a hook fastener on an inner surface of said overlying strap.

7. A respiratory mask and headgear combination according to claim 6 wherein said release actuator is a release cord attached at one end thereof to said inner surface of the overlying strap.

8. A respiratory mask and headgear combination according to claim 7 wherein said release actuator is attached at an upper portion of said inner surface.

9. A respiratory mask and headgear combination according to claim 1 when used as a part of a patient gas delivery system for treatment of a respiratory disease.

10. A respiratory mask and headgear combination comprising a respiratory mask being a patient gas delivery mask having a first side and an opposite second side, and respiratory mask-securing headgear for securing said mask to the face of a wearer, the headgear including at least one strap extending from each of the first and second sides of the mask, the straps in use being releasably fastened at a region rearwards of the facial region of the wearer by fastening means so as to secure the mask, the headgear further including a release actuator acting on the fastening means and in use extending forward from the fastening means to a position substantially at the front of the wearer such that the release actuator may be gripped at substantially the front of the wearer and actuated to release the fastening means and thereby allow removal of the headgear from the wearer, wherein an overlying one of said straps overlies the other of said straps at said fastening means, wherein said release actuator is a release cord attached to said overlying strap at said fastening means and acts to pull said overlying strap away from said other strap to release the fastening means and, wherein the overlying strap has one or more guides through which the release cord passes, such that a distal end of the release cord is located in use at the front of the wearer and may be pulled to actuate release of the fastening means.

11. A respiratory mask and headgear combination according to claim 10 wherein in use a force acting on the headgear due to pulling of the cord acts to retain said other strap against the wearer'"'"'s head whilst pulling away the overlying strap.

12. A respiratory mask and headgear combination according to claim 11 wherein in use further pulling of the cord in substantially the same direction acts to remove the headgear and mask from the wearer.

13. A respiratory mask and headgear combination according to claim 11 the fastening means is located in use at the rear of the wearer'"'"'s head.

14. A respiratory mask and headgear combination comprising a respiratory mask being a patient gas delivery mask having a first side and an opposite second side, and respiratory mask-securing headgear for securing said mask to the face of a wearer, the headgear including at least one upper strap adjustably attached to the first and second sides of the mask and in use passing around an upper portion of the wearer'"'"'s head, and further including at least one lower strap extending from each of the first and second sides of the mask to a lower rear portion of the wearer'"'"'s head, the lower straps in use being releasably fastened at a region rearwards of the facial region of the wearer by fastening means so as to secure the mask, the headgear further including a release actuator acting on the fastening means and in use extending forward from the fastening means to a position substantially at the front of the wearer such that the release actuator may be gripped at substantially the front of the wearer and actuated to release the fastening means and thereby allow removal of the headgear from the wearer.

15. A respiratory mask and headgear combination according to claim 14 wherein the fastening means is located in use at the rear of the wearer'"'"'s head.

16. A respiratory mask and headgear combination according to claim 15 wherein an overlying one of said lower straps overlies the other of said lower straps at said fastening means, wherein said release actuator is attached to said overlying strap at said fastening means and acts to pull said overlying strap away from said other strap to release the fastening means.

17. A respiratory mask and headgear combination according to claim 16 wherein said fastening means includes a hook fastener on an inner surface of said overlying strap.

18. A respiratory mask and headgear combination according to claim 17 wherein said release actuator is a release cord attached at one end thereof to said inner surface of the overlying strap.

19. A respiratory mask and headgear combination according to claim 18 wherein said release actuator is attached at an upper portion of said inner surface.

20. A respiratory mask and headgear combination according to claim 18 wherein the overlying strap has one or more guides through which the release cord passes, such that a distal end of the release cord is located in use at the front of the wearer and may be pulled to actuate release of the fastening means.

21. A respiratory mask and headgear combination according to claim 20 wherein in use a force acting on the headgear due to pulling of the cord acts to retain said other strap against the wearer'"'"'s head whilst pulling away the overlying strap.

22. A respiratory mask and headgear combination according to claim 21 wherein in use further pulling of the cord in substantially the same direction acts to remove the headgear and mask from the wearer.
