ABSTRACT:
Blood units and water units for membrane type blood oxygenator in which blood units are separated from water units by oxygen units; oxygen diffuses through membranes of blood units from oxygen units and water units apply pressure to blood units through intervening oxygen units. The blood unit is formed by a frame having a pair of opposing sides and a pair of opposing ends, the ends being imperforate, the sides being formed with flow-through passages for flow of blood from one blood unit to the next and with lateral passages for flow of a portion of the blood into, through and out of the blood unit, there being a semi-permeable membrane affixed to opposite faces of the frame. The water unit comprises a water impermeable, expansible water mattress having rigid end members formed with water flow-through passages for flow of water from one water unit to the next and having lateral passages for flow of a portion of the water into, through and out of the mattress.
