ABSTRACT:
A generally cylindrical housing supports a pair of rotatable tubing wheels within the housing. Each rotatable tubing wheel supports a quantity of flexible tubing having one end extending outwardly through an aperture in the housing and the remaining end coupled to a rotatable coupler such that gas flow may be produced between the two outer ends of the two flexible tubings. Each rotatable wheel is operatively coupled to a spring-driven ratchet-controlled winding and rewinding mechanism. The rotatable coupler between the interior ends of the two flexible tubes allows for independent rotation of each tubing wheel with respect to the remaining tubing wheel.
