Abstract
A two-cannula syringe for the aspiration and for the injection of medicaments in the form of liquids. The syringe includes a first cannula for the aspiration of the liquid into a cylinder of the syringe and for the possible mixing and/or degassing of the liquid and a second cannula for the actual injection. Both cannulae are present in a protected state, the first cannula being disposed so as to be displaced relative to the second and/or so as to be removable or displaceable in the longitudinal direction of the syringe, and both cannulae being disposed about the same longitudinal axis of the syringe.
