ABSTRACT:
An apparatus and method for projecting a concentrated beam of germicidal ultraviolet radiation onto a preselected target area on the body of a patient undergoing surgery, without substantial emanation of ultraviolet radiation outside the target. A reflector defines a reflective surface and has an axis of reflection, a lamp produces radiation which has a wave length in the ultraviolet C range, and produces substantially no radiation in the ultraviolet A and B ranges, and the lamp is positioned so that a beam of concentrated indirect radiation is reflected from the reflector and extends outwardly along the axis of reflection, a collimator has a casing, closed side walls and opposed open ends, a plurality of plates in the casing are in spaced substantially parallel relation extending between the open ends substantially parallel to and coincident with the axis of reflection with the side walls positioned to cover entirely the side edges of the plates to cause the condensed beam to pass outwardly only through one of the open ends, a housing supports the collimator in alignment with the axis of reflection, and a positioning arrangement positions the housing so as to align the axis of reflection with the target area.
