Abstract:
A chamber for subjecting a stream of infected blood flowing through the chamber to ultraviolet radiation to destroy microorganisms responsible for the infection; said chamber comprising:A. a container having an inlet port and an outlet port and a surface formed by a window transparent to ultraviolet rays;B. an array of parallel baffle plates disposed within the container to define a series of flow channels which are interconnected by free spaces at alternate ends of the plates in the array to create a labyrinthine flow passage running from the inlet port to the outlet port; andC. a transverse bump on either side of each of said plates adjacent the free-space end thereof, said bump acting to agitate the blood stream flowing over the bump to intermingle blood in lower regions of the stream with blood in a higher region thereof adjacent the window whereby blood from the lower regions and the higher region are exposed to ultraviolet rays transmitted through the window, wherein each of said baffle plates is progressively tapered to induce blood from said lower regions to travel to said higher region.
