Abstract

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.
