The device (1) has a housing (2), and a flexible bag arranged in the housing and intended to receive a liquid. A dispensing device, in particular an injection syringe (5), is also arranged in the housing, so that it is removable from the housing. A transfer channel (6) serves for direct or indirect transfer of the liquid from the bag into the dispensing device. At least one pressure plate (7) is also provided, which can be pressed against the bag in order to empty the bag. The pressure plate is preferably activated via a spring mechanism (16), which serves as energy accumulator. The device, according to the invention, makes it possible, with a few manoeuvres, to prepare an injection liquid and deliver it to the injection syringe, with the substances being brought together by a largely automated procedure.

1. A device for reconstitution of injection solutions, said device comprising: a housing,a flexible bag, which is arranged in the housing, for receiving a liquid,a dispensing device which is arranged in the housing and is removable from the housing,a transfer channel for direct or indirect transfer
1. A device for reconstitution of injection solutions, said device comprising: a housing,a flexible bag, which is arranged in the housing, for receiving a liquid,a dispensing device which is arranged in the housing and is removable from the housing,a transfer channel for direct or indirect transfer of the liquid from the bag into the dispensing device, andat least one pressure plate, which is pressable against the bag, for squeezing the bag,wherein the housing comprises a connecting piece for connecting a container containing a second substance, and the connecting piece communicates with at least one element of a group consisting of the transfer channel and the flexible bag by a valve device. 2. device for reconstitution of injection solutions, said device comprising: a housing,a flexible bag, which is arranged in the housing, for receiving a liquid,a dispensing device which is arranged in the housing and is removable from the housing,a transfer channel for direct or indirect transfer of the liquid from the bag into the dispensing device, andat least one pressure plate, which is pressable against the bag, for squeezing the bag,wherein an additional container, which communicates with the transfer channel by a valve device, is arranged in the housing. 3. A device for reconstitution of injection solution, said device comprising: a housing,a flexible bag, which is arranged in the housing, for receiving liquid,a dispensing device which is arranged in the housing, and is removable from the housing,a transfer channel for direct or indirect transfer of the liquid from the bag into the dispensing device, andat least one pressure plate, which is pressable against the bag, for squeezing out the bag,wherein a valve device, for blocking the fluid connection between the flexible bag and the dispensing device, is arranged in the transfer channel, and the valve device is movable into an open position as a result of a lifting movement. 4. A device for reconstitution of injection solutions, said device comprising: a housing,a flexible bag, which is arranged in the housing, for receiving liquid,a dispensing device which is arranged in the housing and is removable from the housing,a transfer channel for direct or indirect transfer of the liquid from the bag into the dispensing device, andat least one pressure plate, which is pressable against the bag, for squeezing out the bag,wherein a mechanical energy storage device is arranged as a driving means in the housing by way of which the at least one pressure plate is pressable against the bag and the dispensing device comprises an injection syringe. 5. The device as claimed in claim 4, wherein a spring mechanism with at least one spiral spring is arranged in the housing, and a drive axis of the spring mechanism is connected to a cam disk for converting the rotational movement into at least one linear force component. 6. The device as claimed in claim 5, wherein the at least one pressure plate is mounted in the housing together with the bag and is mounted so as to be linearly displaceable relative to the cam disk, and the cam disk interacts in such a manner with engagement members on the pressure plate that initially the cam disk carries out a liner movement and is then pressed against the bag maintaining a reached end position. 7. The device as claimed in claim 4, wherein the housing comprises a cover or a handle element and the driving means is activatable as a result of opening of the cover or as a result of actuating the handle element. 8. The device as claimed in claim 4, wherein the injection syringe is mounted in a syringe holder in the housing with the piston retracted, and the injection syringe comprises a needle holder with a fill opening which communicates with the transfer channel, and the fill opening is closable when the injection syringe is removed from the syringe holder. 9. The device as claimed in claim 4, wherein the injection syringe contains a second substance. 10. The device as claimed in claim 5, wherein the at least one pressure plate is designed as two pressure plates and the bag is arranged between the two pressure plates, and each of the two pressure plate has a spring mechanism with a cam disk associated therewith. 11. The device as claimed in claim 10, wherein the two cam disks comprise cam portions which are realized differently in such a manner that the two pressure plates are pressable against the bag in a non-symmetrical movement. 12. The device as claimed in claim 4, wherein at least one spring clamp is mounted in the housing in such a manner in a rest position which is tensioned against a spring force of the at least one spring clamp that, as a result of a lifting movement, the at least one spring clamp is movable out of the rest position into a pressing position in which the at least one pressure plate is pressable against the bag. 13. The device as claimed in claim 12, wherein the housing comprises a cover or a handle element, the driving means is activatable as a result of opening of the cover or as a result of actuating the handle element, the at least one pressure plate is displaceable in the housing as a result of opening the cover or as a result of actuating the handle element and by said displacement, the spring clamp is movable into the pressing position and, at the same time, a valve device, which is arranged in the transfer channel, for blocking the fluid connection between the flexible bag and the dispensing device, is movable into an open position. 14. The device as claimed in claim 7, wherein the housing comprises a handle element, the handle element is realized as a lever which is pivotable about a rotary joint and, in a closed position, secures the dispensing device in the housing and, in an open position, releases the dispensing device. 15. The device as claimed in claim 13, wherein the cover or the handle element is operatively connected in such a manner to the at least one pressure plate by a lever gear unit that rotational movement at the cover or at the handle element is transferrable into a linear movement at the at least one pressure plate.
