  • Patent number: 4813931
    Abstract: This invention relates to a novel, pediatric suction system and method whereby a liquid-impervious filter prevents liquids aspirated into the chamber through a suction tube from traveling into a vacuum tube. Correspondingly, the filter prevents reverse travel of contaminants from the vacuum tube to the suction tube. The filter is liquid impervious and porous with sufficient porosity so as to not interfere with the sensitivity of a partial vacuum applied to the vacuum tube by a physician. The suction tube and vacuum tubes are releasably connected to the container and provision is made for transport of the aspirated liquids.
