PROBLEM TO BE SOLVED: To provide a mixed injection member capable of smoothly performing collection of a fluid in an internal flow passage and injection of a fluid to the internal flow passage, and reliably preventing stagnation of a fluid in the internal flow passage.SOLUTION: A mixed injection member 1 comprises: a main body part 2 that can be connected to a blood circuit in which blood circulates; an internal flow passage α formed in the main body part 2, in which a fluid in the blood circuit can circulate; an introduction flow passage A for introducing the blood into the internal flow passage α and an introduction flow passage B for leading out the blood in the internal flow passage α, which are formed in the main body part 2; and a rubber material 4 attached to an opening 2c formed in the main body part 2 for partitioning between the inside and the outside of the internal flow passage α. The mixed injection member 1 can collect the blood in the internal flow passage α through the rubber material 4 and inject other fluid into the internal flow passage α. The introduction flow passage A is extended while being gradually reduced in diameter toward a position deviated from a center P of the internal flow passage α. |
