Abstract
A hose formed by a plurality of subunits in tandem arrangement particularly useful for use in a breathing apparatus. Each of the subunits comprises a plurality of repeat subunits in tandem arrangement, each of said subunits comprising: a proximal subunit-to-subunit connector member at a proximal end of each subunit; a distal subunit-to-subunit connector member at a distal end of each subunit; at least one interlocking ring; and at least one gas and/or moisture-permeable member disposed intermediate and connected to the at least one interlocking ring and one or both of the proximal and distal subunit-to-subunit connector members. In other embodiments, the member intermediate the interlocking ring and subunit-to-subunit connector members is a non-rigid member, and more particularly has a frusto-conical shape.
