Abstract:
A method of bone cement preparation from a polymeric powder and a liquid component, comprising a polymerisable monomer or comonomer, by action of a catalytic system, whereby particles of said powder component are packed in a powder container (7;35) with an inlet port (8) and an outlet port (9) and the liquid component is held in a liquid container (11), comprising the steps of:A) completely filling said powder container (7;35) with said polymeric powder; B) connecting said liquid container (11) to said inlet port (8); C) connecting a vacuum source (10) to said outlet port (9); and, D) completely flooding a void space between said particles of said powder component with said liquid component, said liquid component flowing from said inlet port (8) toward said outlet port (9) by the action of the vacuum source (10).
