1. A combined irrigator and evacuator for use in bathing a wound with an irrigating solution and removing fluid from the wound, comprising:

  • (a) a rigid housing forming a chamber having opposed ends and a wall, at least one of said ends being substantially planar;

    (b) means under bias for dividing said chamber into a pressure-irrigating section and a suction-evacuating section, said means being substantially planar and substantially parallel to said planar end;

    (c) seal means for preventing fluid flow between said pressure-irrigating section and said suction-evacuating section;

    (d) means for filling said pressure-irrigating section with said irrigating solution against said bias, said bias tending to expel substantially all of said irrigating solution; and

    (e) flow means under selective rate control for simultaneously expelling the irrigating solution from the pressure-irrigating section under said bias towards said wound and for admitting fluid removed from said wound into the suction-evacuating section by vacuum developed by the expelling of the irrigating solution.
