BLOOD STORING VESSEL, BLOOD STORING VESSEL WITH BLOOD FEEDING MECHANISM, AND PUMP-OXYGENATOR

摘要

PROBLEM TO BE SOLVED: To provide a blood storing vessel, by which, when the blood storage amount in the blood storing vessel comes to a designated value or less, a flow of blood flowing out from the blood storing vessel can be decreased, and provide a blood storing vessel with a blood feeding mechanism, and a pump-oxygenator. ;SOLUTION: A blood storing vessel 1 comprises a blood inflow port 11, a blood outflow part 8 having a blood outflow port 12, and a blood storing part 17 for communicating the blood inflow port with the blood outflow part. The blood outflow part 8 includes a blood outflow regulating mechanism 14 for regulating the blood quantity flowing out from the blood outflow part when the blood quantity in the blood storing part comes to a designated value or less. The blood outflow quantity regulating mechanism 14 includes a float 14 having a specific gravity lower than that of blood, a valve element which is connected to the float by a bar-like member 42 and has a specific gravity higher than that of blood, a valve seat part 45 provided in an opening part of the blood outflow part 8, and a guide member 44 for guiding the valve member to the valve seat part.;COPYRIGHT: (C)1998,JPO
