CONSTITUTION: A device wherein a blood sample is selectively sucked from two parts of a pipe and a chem. fluid is injected into the blood is provided a three-direction selecting element 5 which functions within a sheet provided with three connecting parts 2, 3 and 4. The three-directional passage 5a is suitable to selectively connect two of the connecting parts 2, 3 and 4 when an operator actuates it manually. The first connecting part 2 is suitable for receiving a pipe connected with an artery blood sucking part and the second connecting part 3 is connected with the bottom part of a trap 7 whose top part 7a is opened through a conduit pipe 6 and which is suitable for receiving a pipe connected with a vein blood sucking part. The third connecting part 4 is provided with a one-directional valve 10 which allows flow from the connecting part and is connected with the bottom part of the trap 12 whose top part 12a is opened through a conduit 11 and which has a shape which can allow inserting a syringe 15 and sucking the blood sample.
