摘要

The device (100) has an expandable folded sheath support comprising a central opening (115) opened at an interior of an expandable folded sheath. A sheath guide guides the sheath from the support till to a remote outlet plate. The support has a local inlet plate (110) and an arm (130) that extends along the folded sheath. The support comprises concentric hooks that retain an end of the sheath. The guide comprises intermediate cable supports (135, 150) that support corresponding intermediate cables (215B). One of the cable supports is assembled on a screw head (220) fixed at a wall. An independent claim is also included for a method for circulating air.
