  • Patent number: 6592769
    Abstract: A device is provided for the filter and collection of one or more material. The device incorporates a manifold with an inlet conduit and an outlet conduit, with an adjustable control handle on the top of the manifold and a baffle plate in the inside of the manifold. The manifold is sealed to the top opening of a collection chamber. During procedures which require withdrawal of material not to be collected, the control handle and baffle plate are adjusted to a pass-through mode which connects a internal adjustable conduit, which transverses through the baffle plate, with the lumen of the inlet and outlet conduits to form a continuous lumen with which to withdraw material not to be collected through. During procedures which require the withdrawal of material to be collected, the control handle and baffle plate are adjusted to a solids mode which orients the baffle plate to face both the lumen of the inlet and outlet conduits.

  • Patent number: 6149812
    Abstract: A dental environmental filter is provided for the collection of heavy metals and other particles during dental or other procedures. The dental environmental filter incorporates a manifold with an inlet conduit and an outlet conduit, with an adjustable control handle on the top of the manifold and a baffle plate in the inside of the manifold. The manifold is sealed to the top opening of a collection chamber. During procedures which require withdrawal of fluids, the control handle and baffle plate are adjusted to a fluids mode which connects a internal adjustable conduit, which transverses through the baffle plate, with the lumen of the inlet and outlet conduits to form a continuous lumen with which to withdraw fluids through. During procedures which require the withdrawal of heavy metals or other particles, the control handle and baffle plate are adjusted to a solids mode which orients the baffle plate to face the both the lumen of the inlet and outlet conduits.
