Abstract
A conduit tube () that communicates with an intracardiac blood inflow port () and a liquid medicine injection port () and allows blood from the intracardiac blood inflow port and a liquid medicine from the liquid medicine injection port to flow into a cardiotomy section () is inserted from above downward in the cardiotomy section. A blood flow channel () for the flow of blood and a liquid medicine flow channel () for the flow of a liquid medicine are formed independently of each other in the conduit tube. With respect to the vertical direction, the lower end of a blood conduit tube portion () that forms the blood flow channel is located at a lower position than the lower end of a liquid medicine conduit tube portion () that forms the liquid medicine flow channel. This prevents the generation of negative pressure in the liquid medicine flow channel due to the flow of blood. It also reduces the resistance to the inflow of a liquid medicine into the cardiotomy section.
