The device for selectively drawing samples of blood from two sections of a line and for injecting drugs into the blood comprises a three-way selection element which operates in a seat provided with three connections; the ways are suitable for selectively connecting two of the connections upon manual actuation on the part of an operator. The first connection is suitable for receiving a line connected to an arterial blood drawing section; the second connection is connected, by means of a duct, to the base of a trap which is open at the top and is suitable for receiving a line connected to a venous blood drawing section; and the third connection comprises a one-way valve allowing flow away from the connection and is connected by means of a duct to the base of a trap which is open at the top and is shaped so as to allow the insertion of a syringe for drawing samples of blood.
