Abstract
A connection assembly for joining a gas supply line to an article, the assembly comprising a first member having first and second ends, inner and outer walls; and a through passage between said ends; a second member having first and second ends, the second end engagable with the first member via the first end of the first member, the second end of the first member connectable to the article and the first end of the second member connectabte to a gas line; wherein the connection between the first and second members is arranged to allow relative movement between the first and second members such that either of the first and second members are each able to rotate axially relative to the other member through a 360 degrees arc about longitudinal axes through each member and to each move relative to the other member between a first disposition where the longitudinal axes of the first and second members are in alignment and at least one second disposition where at least the second member is disposed at an angle to the longitudinal axis of the first member.

57. A connection assembly for joining a gas supply line to an article, the assembly comprising
a first member having first and second ends, inner and outer walls; - and a through passage between said ends; and
a second member having first and second ends, the second end engagable with the first member via the first end of the first member, the second end of the first member connectable to the article and the first end of the second member connectable to a gas line; wherein the connection between the first and second members is arranged to allow relative movement between the first and second members such that either of the first and second members are each able to rotate axially relative to the other member through a 360 degrees arc about a longitudinal axes through one of the members and to each move relative to the other member between a first disposition where longitudinal axes of the first and second members are in alignment and at least one second disposition where at least the second member is disposed at an angle to a longitudinal axis of the first member. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78)

79. A swivel connector for a gas delivery assembly comprising:
-
a face mask including; a manifold; a face contacting portion which engages the face of a wearer; means to fasten the mask to a face of a wearer; and an inlet which allows delivery of gas from a gas source to the inside of said manifold; and a gas delivery line communicating between a gas source and said manifold; wherein the delivery line is connected to the manifold via the swivel connector which allows 360 degree axial rotation of the delivery line about a longitudinal axis through the supply line and/or swivel movement of the line relative to the mask. - View Dependent Claims (80)

81. A mask assembly for supplying gas under pressure to an airway of a human comprising:
-
a flexible manifold shell, being made of a flexible material, the manifold including means for connection to a gas delivery pipe, at least two side walls which are at least partially comprised of portions of the manifold shell; a first mask shape forming element for distributing distortional forces to a substantial portion of one side wall that attaches to or is integral with a significant portion of that one side wall of the mask; and a second mask shape forming element for distributing distortional forces to a substantial portion of an other side wall that attaches to or is integral with a significant portion of that other side wall of the mask, each mask shape forming element being connected to, or being connectable to, a strap; characterised in the assembly further comprises a gas delivery line communicating between the gas source and said manifold;
wherein the delivery line is connected to the manifold via a swivel connector which allows 360 degree axial rotation of the line about a longitudinal axis through the supply line and/or swivel movement of the line relative to the mask.
