A sealable container (e.g., cylindrical, bottle-shaped, pouch) intended to be used as a component of a surgical suction system to collect aspirated materials (e.g., blood/bodily fluids, gases, body tissues, calculi) from a surgical site for disposal (e.g., to prevent backflow) or diagnostic/therapeutic purposes (e.g., tissue or polyp trap). It may be used singularly or connected in a series to provide greater capacity, and may be graduated to facilitate determination of the quantity of its contents; it may also be used in conjunction with aspiration liners and may include lid, microbial/hydrophobic filters or tubing. This is a single-use device.
