  • Patent number: 10561767
    Abstract: Systems and methods for a cartridge which may be included in a medical suction device are disclosed herein. In one embodiment, a cartridge may comprise a porous filler material loaded with absorption granules for absorbing liquids, and a hydrophobic liquid barrier which is permeable only to one or more of air and gasses, and positioned within the cartridge so that liquids in the cartridge cannot exit the cartridge. The cartridge may further comprise perforated walls and sealed walls, arranged within the cartridge in an alternating order and orientated parallel to one another and perpendicular to a net flow direction of fluids in the cartridge, and spaced from one another such that passages are formed between the walls.
