Abstract
Abstract Lower and upper covers permanently secured together form a vial enclosing chamber in a cap assembly which encloses the top of a bone cement mixing apparatus mixing chamber having prepackaged premeasured bone cement powder. The vial contains a monomer bone cement liquid and may be glass. The vial has two valve seats in corresponding ports on opposing vial side walls sealed by a releaseably secured preferably glass valve member threaded to a nozzle attached to the cap assembly. The vial ports are aligned with a mixing chamber liquid inlet port to permit the cement liquid to flow into the mixing chamber from the opened valves. The vial may be supplied enclosed in a separate package and includes valves on a valve stem attached to the package for opening and sealing the vial. In the alternative, the vial is frangible glass and may be opened by fracturing it and retaining the fragments in the vial receiving chamber to release the liquid to the mixing chamber.
