ABSTRACT:
A multipurpose metabolic assist system has an inlet passageway, an outlet passageway, a treated blood component passageway spaced from the inlet passageway and extending to the outlet passageway. The system has at least one space between at least a portion of the inlet passageway and a portion of the treated blood component passageway, and a particulate treatment agent for treating a component of the blood is packed in said space. At least a portion of the inlet passageway and the treated blood collection passageway which face the space are constituted by a porous membrane having pores of a size smaller than the size of the particles of the treatment agent and of a size for passing a component of the blood to be treated, and blocking passage of the remainder of the blood. A flow obstructor for producing an increased pressure is provided in the inlet passageway. When blood is supplied to the inlet passageway, the component of the blood to be treated is passed through the membranes and the treatment agent and the component is treated and the treated component is collected in the treated blood component passageway and supplied to the outlet passageway.
