摘要： A mixing and/or reconstitution system reduces the possibility of user error and provides a well mixed and/or reconstituted drug in a short time. The system comprises a device containing a first material within a first chamber, a housing, and a plunger, the plunger comprising a second chamber containing a second material, wherein one of the first and the second material is a fluid, and a movable element with an electric, magnetic, or paramagnetic characteristic, wherein the second chamber is initially closed; and a base unit comprising a recess for accommodation of the device, a control unit, and an electromagnetic unit which is adapted to produce an electromagnetic field penetrating the recess, wherein the control unit can electrically operate the electromagnetic unit such that the element contained in the second chamber moves in a direction of the device determined by the electromagnetic field and fluidly communicates the first and second chambers.

摘要： The disclosure refers to a device, for example a cartridge, a syringe or an autoinjector, which reduces the possibility of user error and provides an easy and automatic operation during mixing and/or reconstitution. The device is adapted such that activation of the device causes movement one of a first piston and a second piston in second chamber in an axial direction of the device, thereby moving the other one of the first piston and the second piston into the same axial direction of the device, opening a fluid communication path between the second chamber and a first chamber of the device, and expelling a second material from the second chamber into the first chamber via the fluid communication path. The disclosure is further directed to a respective mixing and/or reconstitution method.
