1. A continuous vacuum wound drainage system, comprising:

  • a drain reservoir capable of being evacuated to a subatmospheric pressure;

    wound connection means for connecting said drain reservoir to a wound and therewith for vacuum draining fluids from the wound;

    vacuum source connecting means for connecting said drain reservoir to a vacuum source and therewith for providing the subatmospheric pressure in said drain reservoir;

    hydrophobic filter means permitting gas flow therethrough but blocking flow of liquid therethrough from said drain reservoir to said vacuum source connecting means for attaining the subatmospheric pressure in a reservoir by said vacuum source while avoiding contamination of a vacuum source by liquid from said drain reservoir;

    baffle means constructed for preventing fatty substances from flowing therethrough, said wound connecting means and said hydrophobic filter means communicating with respective first and second spaces within said drain reservoir, said baffle means defining said first and second spaces.
