<p>By providing a fluid transfer assembly (20,23), two components (26,27) forming bone cement are maintained separately from each other until actual intermixing thereof for use is desired, with the liquid monomer component (27) being completely dispensed from a sealed unit (21,30) directly into the mixing vessel (25) in a closed loop manner, without exposure thereof to the user and without breakage of the container (30) holding the liquid monomer, and a unique multi-component, product handling and delivering system is achieved. The fluid transfer assembly (23) is constructed for cooperating with the sealed vial or tube (20) containing the liquid monomer and the mixing vessel (25) for completely extracting all of the liquid monomer from the vial/tube (30) in a closed loop operation and directly delivering the liquid monomer into the mixing vessel (25) containing the dry powder. This transfer operation is achieved upon demand by the user, while preventing the liquid monomer from being exposed to the user or to the surrounding area.</p> |
