ABSTRACT:
Disclosed is an elongate material management apparatus. It is comprised of a housing removably connected to a base plate that may be opened for the placement of tubing therein. Disposed within the housing is a dual spool to wind and unwind tubing. The dual spool is disposed on a spindle vertically supported on the base plate. The dual spool include a u-turn channel to reverse the direction of the tubing without collapsing it so that the tubing can either wind up or unwind from both of halves of the dual spool simultaneously. The dual spool is energized with a torsional drive that may be a coil spring to wind up unused tubing, one end of which is attached to a slot in the dual spool while the other is attached to the housing to achieve mild tension in the tubing from both directions. The inventive apparatus also includes a ratchet and pawl type device to selectively hold the dual spool in a given position without tension being on the tube when it is not needed. The apparatus includes an interlock that prevents removing the base plate from the housing unless the elongate material has been fully unwound to fully tension the torsion drive, a lock on the dual spool to maintain full tension on the torsion drive when the base plate is removed from the housing to facilitate exchanging elongate materials; and a release button on the base plate to release the stop when the base plate is reassembled with the housing to initiate winding of the elongate material.
