Abstract
A system for use in bone cement preparation can include a chamber for intermixing a liquid monomer and solid polymer components, a container, a vacuum channel, and a filter. The mixing chamber can be configured to hold a non-liquid, polymer powder component of a bone cement. The container can be configured to hold a liquid component of the bone cement. The system can have a first interface disposed between the mixing chamber and the container and a second interface disposed between the mixing chamber and the vacuum channel. The second interface can to receive and position the filter between the mixing chamber and the vacuum channel. The vacuum channel can direct a partial vacuum to draw the liquid component from the container into the non-liquid component in the mixing chamber to intermix the components and to thereby provide a settable bone cement.
