Abstract
An apparatus for mixing bone cement in a vacuum includes a container for mixing first and second components of a bone cement in a vacuum, the container having a sealed body defining an interior space and a selected quantity of the first component disposed in the interior space. The container is provided with an injection port for admitting the second component into the interior space vacuum source. A mixing paddle is disposed in the interior space and connected to a handle therefor extending out of the container. A plurality of indirect pathways extend between the interior space and the exhaust port which permit gas to pass therethrough out of the interior space, but prevent the bone cement first and second components from passing therethrough.
