ABSTRACT:
The invention relates to a syringe-type device for freshly preparing a solution, suspension or dispersion, for example injectable formulations, preferably according to a method for reconstitution in a vacuum. The device is shown in FIG.1. The invention also relates to a method for packing the fresh preparation of the solution, suspension or dispersion in a cylindrical reservoir that can be used in a single or multi-dose syringe provided for the same. This is a method for packing the preparation inside the cylindrical reservoir, which is closed on one side by an injection plunger whose movement in the reservoir is limited. This method is characterised in that the elements to be packed are introduced into the reservoir from the injection plunger side before the reservoir is closed by said plunger. Said reservoir is a tube or ampule which is closed on the other side in advance.
