Abstract
A sealed-type flexible reservoir constituting part of the blood circulating circuit of a membrane-type artificial lung is regulated to a specified volume by a pair of opposing planar restricting members, thereby specifying the amount of blood circulating through the circuit. The reservoir comprises a vessel provided at its upper portion with deaeration ports, a blood inflow tube having two or more side apertures for communication with the interior of the vessel, and a blood outflow port for guiding blood exiting from the vessel. The side apertures are located at a position higher than the blood outflow port, with the blood inflow tube and blood outflow port being spaced away from each other by a predetermined distance, Accordingly, air bubbles carried into the reservoir by the flowing blood may be removed from the deaeration ports without being drawn out through the blood outflow port.
