A device for dry water-jet massage, comprising a tub, which is filled with massage water and runs from a head end to a foot end in a longitudinal direction and from a left side to a right side in a transverse direction, having a film material as a cover closing the tub water-tight on the top side, which film material is simultaneously used as a lying surface for a person (Pe) to be treated and allows the transmission of pressure pulses; a nozzle cart, which can be moved in the longitudinal direction of the tub and bears at least two nozzles (D, D', D"), which nozzles (D, D', D") can be fed via a flexible hose connection with massage water from the tub by means of a pump in order to eject one water jet per nozzle against the bottom side of the film material; a first drive for forward and backward movement of the nozzle cart in the longitudinal direction of the tub, the at least two nozzles (D, D') moving forward and backward in the longitudinal direction of the tub with the movement of the nozzle cart; and a second drive (5, ZR, Z), which moves the nozzles (D, D') in the transverse direction of the tub; wherein two nozzle holders are arranged on the nozzle cart, and wherein one of the nozzles (D, D') is arranged on each of the nozzle holders, wherein each of the nozzle holders is connected to a toothed rack, and wherein each nozzle holder and the nozzles (D, D') are axially displaceable along an axis of the nozzle cart perpendicular to the longitudinal direction of the tub, characterized in that the film material has one or more cavity/cavities on the bottom side of the film, which run in the transverse direction, being directed in use at the person lying on the film material, and shaping the film into one or more elevated portions, which are convex on the top side of the film, and that the toothed rack, as part of the second drive with an own gear of the second drive, allows an individual, independent from each other displacement of each nozzle holder in the transverse direction of the tub. a tub, which is filled with massage water and runs from a head end to a foot end in a longitudinal direction and from a left side to a right side in a transverse direction, having a film material as a cover closing the tub water-tight on the top side, which film material is simultaneously used as a lying surface for a person (Pe) to be treated and allows the transmission of pressure pulses; a nozzle cart, which can be moved in the longitudinal direction of the tub and bears at least two nozzles (D, D', D"), which nozzles (D, D', D") can be fed via a flexible hose connection with massage water from the tub by means of a pump in order to eject one water jet per nozzle against the bottom side of the film material; a first drive for forward and backward movement of the nozzle cart in the longitudinal direction of the tub, the at least two nozzles (D, D') moving forward and backward in the longitudinal direction of the tub with the movement of the nozzle cart; and a second drive (5, ZR, Z), which moves the nozzles (D, D') in the transverse direction of the tub; wherein two nozzle holders are arranged on the nozzle cart, and wherein one of the nozzles (D, D') is arranged on each of the nozzle holders, wherein each of the nozzle holders is connected to a toothed rack, and wherein each nozzle holder and the nozzles (D, D') are axially displaceable along an axis of the nozzle cart perpendicular to the longitudinal direction of the tub, characterized in that the film material has one or more cavity/cavities on the bottom side of the film, which run in the transverse direction, being directed in use at the person lying on the film material, and shaping the film into one or more elevated portions, which are convex on the top side of the film, and that the toothed rack, as part of the second drive with an own gear of the second drive, allows an individual, independent from each other displacement of each nozzle holder in the transverse direction of the tub.
