Description

The present invention relates to a system comprising a fluid nozzle and a fluid completely surrounding the fluid nozzle for generating a fluid jet within the fluid. The present invention also relates to the use of a fluid nozzle in a fluid completely surrounding the fluid nozzle. The present invention also relates to a method for dry massage by means of water jets, which are ejected as fluid jets from a water jet ejizierenden as a fluid on the underside of a lying film.

Water nozzles or water jet nozzles as fluid nozzles are installed inside a tub filled with water as a fluid. The tub is covered by a film serving as a lying surface.

The jet of water ejected from the nozzles spreads within the fluid water of the filled tub and transmits its impulse to the material of the lying surface, which in turn transmits the impulse to the body parts of the user lying on the material. This results in a massaging and / or therapeutic effect on the user. The massaging and / or therapeutic effect depends - in the context of water pressures, which enable the achievement of a therapeutic effect by the impact impinging on the underside of the lying foil impulse - decisively from the pressure of the water jet passing through the fluid water.
The nozzles of the known type used to produce the water jet have a smooth, annular end of the outlet opening. In these nozzles, a relatively large pressure loss occurs when the water jet enters the fluid surrounding the nozzle water. In order to produce a sufficiently strong fluid jet as it passes through the liquid passing through the fluid nozzle through the fluid surrounding the fluid nozzle, therefore, a pump is required which, as well as the conduits connecting the pump to the fluid nozzle, are designed for higher performance. As a result, the massage device is spatially demanding, complicated and also more expensive.

Against this background, it was an object of the present invention to provide a way, with the same pumping power, a greater pressure, or at lower pumping power, the same pressure, exiting from the fluid nozzle fluid, ie the water jet as it enters and passes through the Fluid nozzle surrounding fluid to produce water.

Further preferably between the apexes 5 adjacent jaws 3 on the circumference of the outlet opening 2 of the fluid nozzle 1 recessed, extending in the jet direction of the fluid nozzle 1, inner, preferably circular sector, bulges 8 are provided, still more preferably the diameter of the bulges 8 the distance between the vertices 5 of two adjacent teeth 3 corresponds. In a particularly preferred embodiment, the bulges 8 in the jet direction of the fluid nozzle 1 produce a periodic one-sided serrated edge on the inner wall of the outlet opening 2, as shown in FIG FIG. 2 is shown.

Advantageously, the use of the fluid nozzle 1 with one or more tine (s) 3 at the outlet opening 2 of the fluid nozzle 1 leads to a positive influence on the fluid or water jet: The fluid or water jet can pass through the fluid with less pressure loss , so that at the same pressure of the fluid or water jet, the pump power can be reduced or with the same pump capacity, a higher pressure can be achieved. This is accompanied by a reduction in operating costs at the same pressure or with an improvement in the massaging and / or therapeutic effect with the same pump performance.

The use of at least one fluid nozzle 1 with an outlet opening 2, the at least one prong 3, preferably several prongs 3 at their Edge, leads to the production of a lying on the underside of a person to be treated carrying sheet directed at least one fluid jet, preferably for body massage lying on the reclining, to be treated person by the pressure impulse and / or the heat content of impinging on the Liegefolienunterseite fluid jet. This can be achieved therapeutically - for example only - a massage to relieve cramps, to reduce stress, to relax, to improve blood circulation, to prevent bedsores in bed rest, to prevent and combat rheumatism and arthritis, to eliminate hyperacidity of the Musculature ("muscle soreness"), for pain relief including sports injuries, to intensify physical training, to increase or decrease muscle tone, to purify the body, to increase the efficiency of subsequent therapeutic measures; to increase the metabolic performance, to loosen the subcutaneous tissue, for venous and lymphatic decongestion, to dissolve scar tissue, to activate and attenuate the autonomic nervous system with beneficial effects on the internal organs, to eliminate reversible dysfunction of the spine and to alleviate Back pain, to combat a subacute lumbago (lumbago), to combat mild forms of fibromyalgia, to combat psycho-vegetative dystonia, to prevent and combat cellulite, in mental or muscular fatigue, to combat the cervical and thoracic spider syndrome, to combat the Lumbar syndrome, for the removal of cervical migraine, for combating scoliosis and Hohlrundrücken.
