1. A syringe-connector device for separately administering at least two products in controlled quantities by a single injection comprising:
a reservoir having an inner wall; and
a permanently open hollow plunger devoid of a closing-opening valve configured to be moved within the reservoir, said hollow plunger being open by an internal channel, from an end inserted inside said reservoir to another end in a proximal connection, said hollow plunger forming a sealed barrier with the inner wall of said reservoir, a stroke of the hollow plunger varying a volume of said reservoir according to a position of the hollow plunger from one end to another end in the interior of said reservoir, said proximal connection remaining constantly accessible outside of said reservoir, said reservoir being open at the one end thereof in a distal connection and at the other end thereof to introduce and allow said hollow plunger to circulate.
