Abstract
A blood leak detector includes a housing having top and bottom walls and opposed end walls. Dialysate fluid is received in the housing through a port formed in the bottom wall and is directed upwardly through the housing to an outlet port formed in the top wall at a point directly above the inlet port. Axially aligned cylindrical plugs are mounted in the end walls. One of the plugs houses structure for directing a beam of green light through the effluent dialysate and the other cylindrical plug houses structure responsive to green light for generating an ouptput signal indicative of the opacity of the dialysate. A 70 micron stainless steel screen is wrapped around the cylindrical plugs and functions to prevent gas bubbles flowing into the housing with the dialysate from entering the light beam. The cylindrical screen extends to opposed edges positioned in a spaced apart relationship to define a slot which permits gas flow out of the interior of the cylindrical screen configuration.
