Abstract:
A filter trap for collecting autogenous bone and other cell marrow and blood elements suctioned from a surgical site, comprising:a hollow housing having an inlet and an outlet adapted to be connected in line in the tubing of an aspirator;a generally tubular-shaped filter mesh extending between said inlet and outlet of said housing, one end of said tubular-shaped filter mesh being open to the inlet of said housing so that all of the flow entering said housing enters the interior of said tubular-shaped filter mesh;a substantially planar non-porous sample surface removably disposed and extending completely across the other end of said tubular-shaped filter mesh so as to block flow therethrough and to force flow through a side wall of said tubular-shaped filter mesh; andsupport projections within said housing to support said filter mesh and sample surface in a position spaced apart from an interior surface of said housing, and to permit flow that has passed through the filter mesh to travel along the interior surface of said housing to the outlet thereof.
