Abstract
Abstract An apparatus for treatment of a human body having an enclosure equipped with an inlet and outlet is described wherein the inlet is in fluid communication with a source of liquid under pressure. A portion of the enclosure is provided with an open treatment zone. Opposite the inlet is an obstacle such as an impeller to create turbulence in the treatment zone.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
216 words
An apparatus for the treatment of a human body which comprises an enclosure defined by at least one wall, said enclosure adapted to be placed on said body, said enclosure having at least one opening defining an open treating zone adapted to at least partially contain said body, at least one seal attached to said enclosure and disposed about said opening, said seal adapted to seal the contents of said enclosure from the environment outside of said enclosure, an inlet conduit terminating within said enclosure and passing through said wall, a source of liquid disposed outside said enclosure, said inlet conduit being in liquid flow communication with said source of liquid disposed outside said enclosure, means for causing said liquid to flow, under pressure, from said source through said inlet conduit into said enclosure, an impeller disposed within said enclosure, said impeller disposed opposite the terminus of said inlet conduit and in the path of flow of liquid passing through said inlet conduit, said impeller being disposed a distance away from the terminus of said inlet conduit whereby when liquid from said inlet conduit strikes said impeller, said liquid becomes disposed in said enclosure in a state of turbulence and flows towards said open treating zone, said apparatus further comprising an exit conduit from said enclosure.
Claim 2
Independent Claim
216 words
An apparatus for the treatment of a human body which comprises an enclosure defined by at least one wall, said enclosure adapted to be placed on said body, said enclosure having at least one opening defining an open treating zone adapted to at least partially contain said body, at least one seal attached to said enclosure and disposed about said opening, said seal adapted to seal the contents of said enclosure from the environment outside of said enclosure, an inlet conduit terminating within said enclosure and passing through said wall, a source of liquid disposed outside said enclosure, said inlet conduit being in liquid flow communication with said source of liquid disposed outside said enclosure, means for causing said liquid to flow, under pressure, from said source through said inlet conduit into said enclosure, an impeller disposed within said enclosure, said impeller disposed opposite the terminus of said inlet conduit and in the path of flow of liquid passing through said inlet conduit, said impeller being disposed a distance away from the terminus of said inlet conduit whereby when liquid from said inlet conduit strikes said impeller, said liquid becomes disposed in said enclosure in a state of turbulence and flows towards said open treating zone, said apparatus further comprising an exit conduit from said enclosure.
