1. A mixing device for mixing a mixable material and adapted for applying vacuum, the mixing device comprising at least one cartridge and one closure, whereby the at least one cartridge contains a first powder component of the mixable material and comprises a cartridge head, in which at least one ventilation opening is arranged and the closure is arranged at the cartridge head in such manner that the at least one ventilation opening in the cartridge head can be closed and opened by means of the closure, wherein the closure is supported such that it is rotatable or shiftable with respect to the cartridge head and that when the closure is closed, vacuum can be drawn in the cartridge head and in that a connection extends through the cartridge head or a cartridge wall into the inside of the cartridge and connects the inside of the cartridge to a closed container for a second liquid component of the mixable material and further wherein a filter and/or a sieve is arranged between the at least one ventilation opening in the cartridge head and the inside of the cartridge that is filled with the first component and the closure is arranged between the cartridge head and the filter or sieve, whereby at least one part of the closure extends through the cartridge head. 2. The mixing device according to claim 1, wherein the connection is a tube or a hose, whereby a valve is arranged between the connection and the container. 3. The mixing device according to claim 1, wherein the connection is shiftable in the cartridge head along an axis of symmetry of the connection. 4. The mixing device according to claim 1, further comprising: a pore filter arranged between the at least one ventilation opening in the cartridge head and the inside of the cartridge that is fillable with the first component. 5. The mixing device according to claim 1, further comprising: a dispensing tube or a fastening facility for a dispensing tube, whereby the dispensing tube is closable by means of a removable dispensing tube closure. 6. The mixing device according to claim 1, wherein the connection comprises a lateral outlet in a region of a end of the connection that extends into the inside of the cartridge. 7. The mixing device according to claim 1, wherein the connection comprises a predetermined breakage site between a lateral outlet into the inside of the cartridge and the container, in the region of the lateral outlet. 8. A mixing device according to claim 4, wherein the closure is arranged between the cartridge head and the pore filter, whereby at least one handle of the closure extends through the at least one ventilation opening in the cartridge head. 9. The mixing device according to claim 1, further comprising: two ventilation openings arranged in the cartridge head and closable through two blades of the closure, whereby the ventilation openings and the blades are designed as circle segments, and the closure is rotatable. 10. The mixing device according to claim 1, wherein the closure has at least one handle arranged thereon by means of which the closure can be rotated or shifted. 11. The mixing device according to claim 5, further comprising: a handle part connected or connectable to the dispensing tube or a mixing rod that extends through a centric opening in the cartridge head from an exterior to the inside of the cartridge and is usable to rotate the dispensing tube or the mixing rod inside the cartridge. 12. The mixing device according to claim 11, wherein the dispensing tube closure is a stopper on the inside of the dispensing tube that is connected to the handle part by means of which the stopper is removable from the dispensing tube. 13. The mixing device according to claim 4, further comprising: at least one mixing vane arranged on a dispensing tube or on the mixing rod and in that the dispensing tube or the mixing rod having the at least one mixing vane is supported in the cartridge such that it can be rotated. 14. The mixing device according to claim 1, further comprising: a vacuum connector arranged in the cartridge head or in a wall of the cartridge as a feed-through and comprises a valve closure for opening and closing the vacuum connector. 15. A mixing device according to claim 1, further comprising: a feed plunger for dispensing the cartridge content arranged in the cartridge bottom. 16. The mixing device according to claim 1, wherein the first component is a cement powder for a PMMA bone cement, and the second component is a monomer liquid. 17. A vacuum cementing system comprising the mixing device according to claim 1. 18. A method for mixing a mixable material with the mixing device according to claim 1, the method comprising: A) sterilizing the inside and the content of the cartridge through the at least one open ventilation opening in the cartridge head;B) closing the at least one ventilation opening in the cartridge head by means of rotating or shifting the closure with respect to the cartridge head or by means of rotating or shifting the cartridge head with respect to the closure;C) evacuating gases from the inside of the cartridge;D) feeding the second component of the container into the cartridge; andE) mixing the first and the second component to form a mixture. 19. The method according to claim 18, further comprising: applying the mixture through a dispensing tube. 20. The method according to claim 18, wherein, once the second component has been fed into the inside of the cartridge, the connection to the container is severed and the non-centric passage for the connection to the container is closed by means of rotating or shifting (i) the closure with respect to the cartridge head or (ii) the cartridge head with respect to the closure.
