ABSTRACT:
A bone cement mixing apparatus is provided for mixing solid and liquid bone cement components. The apparatus includes a common receptacle base having an interior base surrounded by a continuous side wall with an access opening for accessing the interior. A lid is provided for forming a closure over the top of the receptacle base, the lid having a smaller access opening therethrough. A pair of modular inserts can be selectively placed within the interior of the common receptacle base. The modular components include a mixing bowl and a mixing syringe. Thus, the user can place the bowl or syringe as desired within the receptacle base before mixing bone cement therein. Impellers are provided for each of the mixing vessels including the bowl and the syringe. A vacuum line is provided for sectioning air and gases from the interior of the receptacle base during an addition of liquid or solid bone cement components to either the bowl or the syringe via the smaller access opening in the lid. Because of the smaller size of the access opening in the lid, the vacuum creates a very high velocity air flow that quickly removes noxious odors that are caused by monomers for example such as methyl-methacrylate.
