Abstract
A blood and perfusate filter apparatus having a pair of molded housing members that are substantially identical in their configuration. The upper housing member having a pyramidal-shaped reservoir formed in the upper surface thereof which acts as a secondary distribution reservoir, and the lower housing member having a pyramidal-shaped reservoir formed in the lower surface thereof which acts as a secondary collection reservoir. Interchangeable tubing couplings are press-fit bonded to inlet/outlet ports located in the secondary reservoirs. A filter element, mounted in a resinous band, is bonded between the housing members so as to filter blood or perfusate as it passes through the filter. The filter element also forms primary distribution and collection reservoirs with respect to the upper and lower housing members. Different types of filter configurations, such as flat or pleated, can be mounted in a resinous band and used as the filter media.
