A compression chamber is formed by two end walls 10 and a flexible tubular member 11 extending between the end walls. The flexible tubular member is formed from an inner tube (12, Fig 2) of air impermeable material and an outer tube (13, Fig 2) of a seamless woven material. The inner tube is unstressed when the chamber is filled with oxygen or air and the outer tube bears the pressure load. The tubular member may have first and second ends, each end being held be respective first and second clamping means (24, 25, 26, Fig 2). The end walls may be annular and rigid. At least one of the first and second clamping means may have a normal diameter that is less than the diameter of the end walls and may be expandable to allow an end wall to be inserted into an end of the tubular member before reverting to said normal diameter. |
