Claim 8:
9. Method according to claim 7, characterized in that the displacement of the barrel (30) relative to the plunger-type stopper is effected by means of manual exertion of an actuating force acting in a first direction on a first end (38) of a rocking device (34), whereby at a second end of the rocking device (34), which is arranged opposite the first end (38) and which at least partially encloses the barrel (30), a lever force acting in a second direction is transmitted to the barrel (30), wherein the first direction is substantially opposite the second direction by
(i) holding the plunger-type stopper in the predetermined position within the syringe cylinder by means of exerting a holding force on the plunger-type stopper via a fixable plunger (44) which constitutes part of the displacement device (40, 42, 44, 46, 48) and which is adapted to displace the plunger-type stopper relative to the setting barrel (30) and which rests against a plunger guide (42) with a depth stop (46) arranged thereon, and
(ii) exerting a compressive force on a first end (38) of an elongated plate-like element (34), thereby transmitting to the barrel (30), at a second end arranged opposite the first end (38) and at least partially surrounding the barrel (30), a lever force whose direction is substantially opposite to the compressive force,, so that the plunger-type stopper emerges completely from the barrel (30) and expands so that it comes into contact with an inner surface of the syringe cylinder.
