A closure device (10) is disclosed for use with an access port (62,72,82,92) of a medical respiratory apparatus (60,70,80,90). The closure device (10) comprises a cap (14) that seals the access port (62,72,82,92) save for an opening (28) in the cap (14), and a closure (16) for sealing the opening (2
A closure device (10) is disclosed for use with an access port (62,72,82,92) of a medical respiratory apparatus (60,70,80,90). The closure device (10) comprises a cap (14) that seals the access port (62,72,82,92) save for an opening (28) in the cap (14), and a closure (16) for sealing the opening (28). The cap (14) includes a portion of flexible material (26) in which the opening (28) is formed, and is hingedly mounted with respect to the access port (62,72,82,92).

The invention claimed is: 1. A closure device for use with an access port of a medical respiratory apparatus, the closure device comprising a cap for sealing the access port save for an opening in the cap, and a closure for sealing the opening, the cap including a portion of a first, elastomeric material in which the opening is formed, and a portion of a second, more rigid plastics material that is different from the first material, and the cap being hingedly mounted with respect to the access port so as to be rotatable relative to the access port about a single hinge axis between an open position, in which the access port is not obstructed by the cap, and a closed position in which the access port is sealed save for the opening in the cap. 2. A closure device as claimed in claim 1, wherein the cap is hingedly mounted on a support body of the closure device engageable with the medical respiratory apparatus. 3. A closure device as claimed in claim 2, wherein the support body is adapted to be closely received, in use, internally of the access port. 4. A closure device as claimed in claim 2, wherein the cap is mounted on the support body by at least one hinge. 5. A closure device as claimed in claim 4, wherein the cap is mounted on the support body by at least two separate hinges which hinge about the same hinge axis. 6. A closure device as claimed in claim 4, wherein the cap is attached to the support body by one or more arms, and each hinge is formed by a narrow transverse portion of reduced thickness on each arm. 7. A closure device as claimed in claim 1, wherein the cap is rotated from its closed position to its open position through an angle of 135�� or greater. 8. A closure device as claimed in claim 1, wherein the closure device is formed using a two-shot injection moulding process which involves injection moulding the relatively rigid plastics material and subsequently injection moulding the elastomeric material onto the relatively rigid plastics material. 9. A closure device as claimed in claim 1, wherein the closure is hingedly mounted with respect to the opening. 10. A closure device as claimed in claim 9, wherein the closure is hingedly attached to the cap at the opposite side of the cap to that at which the cap is hingedly mounted to the support body. 11. A medical respiratory apparatus comprising an access port and a closure device as claimed in claim 1. 12. A medical respiratory apparatus as claimed in claim 11, wherein the closure device is integrally formed with the apparatus. 13. A medical respiratory apparatus as claimed in claim 11, wherein the closure device is formed as a separate component that is engageable with the remainder of the apparatus. 14. A closure device, for use with an access port of a medical respiratory apparatus, the closure device comprising: a cap for sealing the access port save for an opening in the cap, and a closure for sealing the opening, wherein the cap includes a portion of a first, elastomeric material in which the opening is formed, and a portion of a second, more rigid plastics material that is different from the first material, and the cap being hingedly mounted with respect to the access port so as to be rotatable relative to the access port about a single hinge axis, and wherein the cap is movable between an open position, in which the access port is not obstructed, and a closed position in which the access port is sealed save for the opening in the cap, and the cap is resiliently biased towards both the open position and the closed position by means of a resilient member that forms part of the closure device. 15. A closure device as claimed in claim 14, wherein the resilient member is arranged such that it is subjected to a gradually increasing tension as the cap is urged by a user away from either the open or closed position and a maximum tension when the cap is at a position approximately midway between the open and closed positions. 16. A closure device as claimed in claim 15, wherein the resilient member is a band of resilient material disposed between the cap and the support body. 17. A medical respiratory apparatus comprising an access port and a closure device as claimed in claim 14. 18. A closure device for use with an access port of a medical respiratory apparatus, the closure device comprising a cap for sealing the access port save for an opening in the cap, and a closure for sealing the opening, the cap including a portion of a first, elastomeric material in which the opening is formed, and a portion of a second, more rigid plastics material that is different from the first material, the first material being a thermoplastic elastomer, and the cap being hingedly mounted with respect to the access port so as to be rotatable relative to the access port about a single hinge axis between an open position, in which the access port is not obstructed by the cap, and a closed position in which the access port is sealed save for the opening in the cap. 19. A closure device as claimed in claim 18, wherein the cap is hingedly mounted on a support body of the closure device engageable with the medical respiratory apparatus. 20. A closure device as claimed in claim 19, wherein the support body is adapted to be closely received, in use, internally of the access port. 21. A closure device as claimed in claim 19, wherein the cap is mounted on the support body by at least one hinge. 22. A closure device as claimed in claim 21, wherein the cap is mounted on the support body by at least two separate hinges which hinge about the same hinge axis. 23. A closure device as claimed in claim 21, wherein the cap is attached to the support body by one or more arms, and each hinge is formed by a narrow transverse portion of reduced thickness on each arm. 24. A closure device as claimed in claim 18, wherein the cap is rotated from its closed position to its open position through an angle of 135�� or greater. 25. A closure device as claimed in claim 18, wherein the cap is resiliently biased towards both the open position and the closed position by means of a resilient member that forms part of the closure device. 26. A closure device as claimed in claim 25, wherein the resilient member is arranged such that it is subjected to a gradually increasing tension as the cap is urged by a user away from either the open or closed position and a maximum tension when the cap is at a position approximately midway between the open and closed positions. 27. A closure device as claimed in claim 26, wherein the resilient member is a band of resilient material disposed between the cap and the support body. 28. A closure device as claimed in claim 18, wherein the closure device is formed using a two-shot injection molding process which involves injection molding the relatively rigid plastics material and subsequently injection molding the elastomeric material onto the relatively rigid plastics material. 29. A closure device as claimed in claim 18, wherein the closure is hingedly mounted with respect to the opening. 30. A closure device as claimed in claim 29, wherein the closure is hingedly attached to the cap at the opposite side of the cap to that at which the cap is hingedly mounted to the support body. 31. A medical respiratory apparatus comprising an access port and a closure device as claimed in claim 18.
