Abstract
There is disclosed a syringe for the storage and application of at least two injection media which are to be administered at different parts of a body and at different times. The syringe comprises a cylindrical syringe body and a piston guided slideably therein and being detachably fastened to an actuating rod. At a selectable distance between the piston in its original position and the syringe cone a floating piston is arranged which divides the syringe body into two compartments. For the injection procedure a needle with one pointed end is attached to the syringe cone and after the first compartment has been emptied a double needle is attached to the cone, which double needle pierces the floating piston and thus opens the second compartment.
