  • Surgery plume filter device and method of filtering
    Patent number: 6203762
    Abstract: A filter device and method of filtering components from a surgery plume. The filter device comprises an integral solution reservoir which intercepts an airstream passage and airstream and cooperates with the airstream to direct air and solution into pads to create a foam. The foam created by the pads and solution and additional elements of the filter react with one or more undesirable components of the surgery plume to cleanse the airstream prior to exhaustion into the atmosphere. No separate solution supply or delivery system is necessary.
    Type: Grant
