Abstract
A system for preparing an injection includes a first container with a first cavity and a rigid outer wall and two ends, a movable stopper being provided on one side of the first cavity, which sealingly closes this cavity and is displaceable inside the first container and comprising a second container, which encloses a second cavity, one container comprising a first substance, and the other container comprising a second substance. The second container comprises an at least regionally elastic wall and in this way has a variable volume. The second container is designed such that a pressure can be built inside the second container by way of the at least regionally elastic wall. The second container is a tube.

A system for preparing an injection, the system comprising
- a first container defining a first cavity for a first substance and having a rigid outer wall and two ends;
- a movable stopper provided on one side of the first cavity which sealingly closes the first cavity and is displaceable inside the first container;
- and
- a second container enclosing a second cavity for a second substance, the second container being a tube,
- wherein the first container and the second container are connected to one another such that the first and second cavities are in fluid connection with one another,
- wherein the second container includes an at least regionally elastic wall so as to have a variable volume, the at least regionally elastic wall operable to build a pressure in the second container.
A combination of a syringe or carpule and a tube comprising at least one regionally elastic wall, the combination selected such that a volume provided in the syringe and a volume provided in the tube are matched to one another such that the syringe is able to receive a defined amount of a first substance and the tube is able to receive a defined amount of a second substance, and at least a partial volume from the syringe or carpule is introducible into the tube, so as to build a positive pressure in the tube and expand the at least one regionally elastic wall.
