This syringe consists of a device for connecting the piston with one end of the piston rod during first perfusion. It also includes a device for disjointing the piston from the piston rod for another perfusion. Based on the present invention, the connecting device between the piston and piston rod includes an intermediate storage element. When perfusion is carried out, it guarantees the junction of the piston with the piston rod, i.e. the pressure acting upon the piston rod during injection staggers the intermediate storage element from the two parts mentioned above, so that the aforementioned parts are disjointed when the second perfusion is to be carried out. |
