In order to keep hose for oxygen delivery off of the floor and thus make use of the oxygen delivery system safer, a storage system for storing the hose includes a support structure, a first pulley assembly, and a second pulley assembly below the first pulley assembly. At least a part of the first pulley assembly is translationally fixed relative to the support structure, and the second pulley assembly is translationally movable relative to the first pulley assembly, along the support structure. The hose is wrapped around pulleys of the first pulley assembly and pulleys of the second pulley assembly, and the amount of hose stored in the storage system is dependent on a position of the second pulley assembly relative to the first pulley assembly. |

1. A storage system for storing a length of a tubular structure, the storage system comprising:
a support structure; a first pulley assembly comprising a plurality of first pulleys, at least a part of the first pulley assembly being translationally fixed relative to the support structure, the plurality of first pulleys being rotatable about a first axis of rotation; and a second pulley assembly translationally movable relative to the first pulley assembly and relative to the support structure, the second pulley assembly comprising at least one second pulley, the at least one second pulley being rotatable about a second axis of rotation, wherein the at least one second pulley comprises a plurality of second pulleys, the number of second pulleys being one less than the number of first pulleys, wherein the first pulley assembly comprises a first housing and a first shaft extending through the first housing, the plurality of first pulleys being rotatable about the first shaft defining the first axis of rotation, wherein the second pulley assembly comprises a second housing and a second shaft extending through the second housing, the at least one second pulley being rotatable about the second shaft defining the second axis of rotation, wherein the second pulley assembly includes a braking system, the braking system comprising:
a shaft that is movable between a first position and a second position; anda tab connected to the shaft, wherein a pulley of the at least one second pulley comprises a slot into which a portion of the tab is insertable when the shaft is in the second position, and wherein the second pulley assembly is movable along the support structure when the shaft is in the first position, and the second pulley assembly is not movable along the support structure when the shaft is in the second position. |
