Modular photochemotherapy chamber

摘要

A modular chamber construction for providing ultraviolet light irradiation within a confined space. The chamber comprises a plurality of side panel assemblies mounted on a base member and arranged to form a vertically upstanding enclosure of polygonal configuration. Two of the panels are hinged to provide doors, with the remaining panels being bolted to the base and to each other. Each of the panel assemblies contains a plurality of long, tubular fluorescent lamps and associated ballast circuits, with the lamp vertically oriented and juxtaposed to face the interior of the enclosure. A top member containing filtered ventilating fans and downwardly facing mirror configuration is bolted to the top edges of the stationary side panels by means of a peripheral flange which permits mounting by sliding the top member horizontally onto the enclosure through the door opening. Each side panel has an outer cover with top and bottom vents, and a light shield may be disposed at the upper end of each side panel to prevent direct leakage of ultraviolet light through the top vents. A removable stand with a mirror surface facing upwardly is disposed on the base member within the enclosure to elevate the subject of irradiation above the dark lower end regions of the vertically disposed lamps. One side panel contains a control unit and viewing window, with the control unit being interconnected to the ballast circuits of the other side panels by plug-in cables. The doors are magnetically latched, and an interlock switch on the top member deenergizes the lamps when the doors are opened.
