Abstract
The invention relates to an automatic syringe for injecting two or more different injection liquids which may not be in contact with each other for long periods of time. For that purpose, the ampoule between the piston and the needle connection includes one or more stoppers which keep the injection liquids separated from each other, while at a point a short distance before the needle connection a by-pass means is present through which the injection liquid or injection liquids present behind the stopper or stoppers can pass the stopper or stoppers during use of the syringe.
