Modular photochemotherapy chamber
First Claim
1. A modular photochemotherapy chamber comprising, in combination:
- a substantially horizontal base member;
a plurality of side panel assemblies mounted vertically upright on said base member and arranged to form an enclosure;
each of said side panel assemblies including a plurality of phototherapy lamps disposed vertically thereon and facing the inside of said enclosure, said lamps being adapted, when energized to emit substantially only ultraviolet light;
means at one end of each of a subplurality of said side panel assemblies for removably attaching the panels to said base member;
a substantially horizontal top member covering said enclosure and removably attached to the other end of each of said subplurality of side panel assemblies;
at least one of said side panel assemblies not of said subplurality thereof being removably attached by hinges to an adjacent side panel assembly to thereby provide a door for said enclosure;
means in said top member for ventilating said enclosure anda removable stand disposed on said base member within said enclosure and having reflector means thereon facing toward the top of said enclosure, said stand having a top portion located above the lower ends of said vertically disposed lamps.

Abstract
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.
