An improved tissue specimen trapping device for collecting and separating solid particles and materials from body fluids has a porous separator that rests on a shelf-like annular ledge between upper and lower portions of the tissue collection container. At least one tissue collection basket removably disposed in the tissue collection container above the separator shelf has a porous bottom surface to filter tissue specimens from body fluids and has downward projections to the tissue collection basket above the separator shelf to create a space therebetween. To ensure that each tissue collection basket is properly and securely positioned within the tissue collection container, a group of cooperating projections and recesses on the inside circumferential wall of the tissue collection container and on the outside arcuate walls of the tissue collection baskets, and/or on the outer surface of the central column within the tissue collection container and on the inner arcuate walls of the tissue collection baskets are used. At least one projection on the underside of the cover rubs against the upper edge of the side walls of the tissue collection baskets as the projection passes over the upper edges of the side walls of each tissue collection basket when the cover is rotated on the tissue collection container provides a tactile indication that the fluid/tissue inlet port is aligned with respect to a tissue collection basket within the tissue collection container. |
