The application relates to a vacuum mixing device for bone cement, where the monomer is pressed into a mixing container due to the surrounding vacuum and a gas volume present in the monomer container.

Vacuum mixing device for bone cement and method for mixing bone cement in said device

The application relates to a vacuum mixing device () for bone cement, where the monomer is pressed into a mixing container () due to the surrounding vacuum and a gas volume present in the monomer container ().

The invention relates to an implant material comprising a polymer which is partially cross-linked by means of a metal acrylate salt.

Method for producing a cross-linked polyacrylate polymer implant material

A device for mixing and applying mixed material, in particular medical cement, comprising a cartridge cylinder, a mixer, a plunger for closing the mixed material cavity and for forcing out the mixed material from the cartridge cylinder, and a latching ring having radially outer and inner hook formations. First counter-hooks on the cartridge cylinder interact with the radially outer hook formations on the latching ring. The plunger has second counter-hooks which interact with the inner hook formation on the latching ring in order to hold the plunger during the mixing, and release the plunger for being displaced at the beginning of the application procedure.
