Abstract

A mask for use in delivering gas to a user and which accommodates relative movement of a connecting gas supply line. The mask has a face contacting portion which is shaped to define a chamber through which gas is delivered to the respiratory tract of the user and, in a preferred form of the mask, the face contacting portion is formed with a convex end region which is arranged in use of the mask to be depressed by and to accommodate facial features of the user. A gas supply port is formed integrally with a wall portion of the chamber and the port provides for connection of a supply of pressurised gas to the interior of the chamber. The mask is characterised in that the wall portion that contains the gas supply port is formed to exhibit a degree of flexibility that is greater than that of adjacent regions of the mask, whereby any movement that is referred to the mask by the connecting gas supply line will be accommodated, at least in part, by flexing the wall portion that contains the gas supply port.
