FIELD: medicine.
SUBSTANCE: invention relates to injection preparation systems. Injection preparation system comprises a first container, which has a first hollow space and has a solid outer wall, as well as two ends; several second reservoirs, wherein each second container surrounds the second hollow space. At that, on one side of the first hollow space there is a movable plug, which hermetically closes and is made with possibility of displacement inside the first container; first container is connected to any of second reservoirs so that their hollow spaces are located with each other in connection with passage of fluid medium. Each of the second containers includes at least in some places an elastic wall and a variable volume; each of the second containers is designed so that pressure is created inside the second container by means of at least some places of the elastic wall. System has in the first reservoir a certain amount of the first substance and has a different amount of the second substance in the second reservoirs; the first reservoir can be combined with one of the second reservoirs for providing an injection solution with different concentrations.
EFFECT: invention provides more complete and homogeneous mixing of medical liquids.
