Abstract
Abstract A device for hydraulic massages comprising: (A) a spray enclosure consisting of a drainage hood (5) and a sump (8) and (B) at least one spray nozzle (9) controlled by a coordinate guide (13). A patient is placed upon the readily deformable impact area (1) and is separated from direct contact with the working fluid. The patient support may consist of a flexible screen (2) in the form of a tensioned cable grid supported by a frame (3) on supports (4). The sump (8) may be bounded by a perforated draining partition (7) splitting off an additional compartment of the sump (8) named reservoir (12). Fluid drained into the sump (8) and the reservoir (12), if any, may be reused.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A hydraulic massage apparatus comprising: a resilient support screen; a hood of flexible sheet material covering said support screen and extending downwardly therefrom, said hood forming a flexible surface above said support screen upon which the body of an individual to be treated can repose; means defining a receptacle for massage water below said hood and cooperating therewith to receive water collected in said hood; a nozzle mounted in said receptacle and trained upwardly toward said surface for directing a jet of water against said surface whereby said individual is massaged through said surface with said jet without said water coming in direct contact with said body of an individual; and means connected with said nozzle for displacing said nozzle in at least two directions of a coordinate system to sweep said jet against said surface.
Claim 2
Dependent Claim
136 words
A hydraulic massage apparatus comprising: a resilient support screen; a hood of flexible sheet material covering said support screen and extending downwardly therefrom, said hood forming a flexible surface above said support screen upon which the body of an individual to be treated can repose; means defining a receptacle for massage water below said hood and cooperating therewith to receive water collected in said hood; a nozzle mounted in said receptacle and trained upwardly toward said surface for directing a jet of water against said surface whereby said individual is massaged through said surface with said jet without said water coming in direct contact with said body of an individual; and means connected with said nozzle for displacing said nozzle in at least two directions of a coordinate system to sweep said jet against said surface.
Claim 3
Dependent Claim
54 words
The apparatus defined in claim 1 wherein said receptacle has an elevated perforated partition delimiting a reservoir in said receptacle for collected water, said nozzle being provided within said partition, said receptacle being further provided around said partition with an outer chamber receiving a portion of said hood hanging downwardly into said outer chamber.
Claim 4
Dependent Claim
29 words
The apparatus defined in claim 2 wherein said means connected with said nozzle includes roller means for supporting said receptacle and enabling displacement of said receptacle along a surface.
Claim 5
Dependent Claim
45 words
The apparatus defined in claim 2 wherein said means connected with said nozzle includes means enabling rotation of said nozzle about an axis and for displacing said nozzle horizontally so that said jet describes at least one cycloidal pattern against the underside of said surface.
