Abstract:
1. A bone cement preparation system comprising: a saturation chamber configured to hold a non-liquid component of a two-part bone cement, the saturation chamber having distal and proximal ends; a funnel configured to direct a liquid component of the two-part bone cement to the saturation chamber, the funnel being attached to or part of the proximal end of the saturation chamber; a filter positioned at the distal end of the saturation chamber; a vacuum source for manually creating a vacuum comprising: a base configured to removably or fixedly position the saturation chamber and the vacuum source in an upright position in which the funnel is disposed at a higher vertical position relative to the filter and the size of the vacuum chamber increases when the actuation member moves toward the higher vertical position; and a flow channel extending between the filter and the vacuum chamber, the flow channel being in fluid communication with the vacuum chamber and the saturation chamber, wherein the system is configured such that increasing the size of the vacuum chamber draws the liquid component into the non-liquid component to combine the components to thereby provide a settable bone cement, and wherein the vacuum source and the saturation chamber are part of or connected to the base such that the system is self-supporting and remains upright while manually operated to create a vacuum, without requiring the user to hold the vacuum source or the saturation chamber in either hand.
