ABSTRACT:
The present invention includes a retracting tubing reel for use in the delivery of therapeutic gas and a method for replacing fluid flow conduit in a retracting tubing reel used in the delivery of therapeutic gas to a patient. The retracting tubing reel comprises a housing wherein the housing includes at least two casing members that when mated together form an encasement for at least a portion of the retracting tubing reel. The casing members are releasably couplable to each other so that when each is disengaged from the other an interior of the housing is exposed. An inlet flow conduit passing through the housing provides fluid communication between an exterior end of the inlet flow conduit located outside the housing and an interior end of the inlet flow conduit located inside the housing. A flexible flow conduit is retractable into a coiled orientation within the housing. The flexible flow conduit is releasably couplable to the interior end of the inlet flow conduit so that the flexible flow conduit is removable from the housing while in the coiled orientation thereby facilitating the replacement of the flow conduit with another similarly coiled flow conduit.
