1. A mixing device for preparing bone cement, comprising:
- a rod;
a mixing container attached to the rod;
a plate attached to the mixing container; and
a monomer container attached to the mixing container via the rod, wherein the rod is moveable relative to the mixing container, the rod being guided through the plate, the plate being detachable such that the plate is moveable to expel bone cement after the bone cement has been prepared.

20. A mixing device for preparing bone cement, comprising:
-
a rod; a mixing container attached to the rod; a monomer container attached to the mixing container via the rod and having first and second telescoping parts, wherein the rod is moveable relative to the mixing container; and a cannula attached to the monomer container and the rod, the cannula being adapted to pierce the monomer container, wherein one of the first and second telescoping parts of the monomer container includes at least one catch hook and the other of the first and second telescoping parts of the monomer container includes at least one catch lug for engagement beneath the respective at least one catch hook such that the monomer container is locked in position relative to the mixing container when the cannula pierces the monomer container.
