DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a hydrodynamic massage device. More particularly, the device according to the invention comprises a bathtub and injection orifices associated with supply means for producing hydrodynamic jets directed interiorly of the bathtub.
BACKGROUND OF THE INVENTION
The patient who is to receive the massage is positioned in the bathtub filled with water and the hydrodynamic jets issued from injection orifices massage the body of the patient. By "hydrodynamic jets" is meant jets of water under pressure, the water having been recovered via outlets situated at the base of the bathtub, it being possible to emit these water jets at the same time as jets of blown air. In this type of device, the known embodiments are distinguished from one another by the more or less significant number of injectors distributed at the base and about the periphery of the bathtub and by the possibilities of varying the pressure or the flow rate of the hydrodynamic jets. Nevertheless, the possibilities for varying the characteristics of the hydrodynamic massage as a function of the treatment to be applied are relatively few with the known devices.
In particular, there are known from the documents FR-A-2 382 888 and FR-A-2 630 911, hydrodynamic massage devices comprising a bathtub and injection nozzles distributed on two opposite surfaces of the bathtub and producing hydrodynamic jets which are oriented by suitable control means. But according to these documents, the control movements of the injection nozzles are effected in essentially horizontal planes, and therefore do not permit simulating the enveloping movements performed by masseurs and kinesitherapists.
SUMMARY OF THE INVENTION
The object of the present invention is to overcome these disadvantages by proposing a new hydrodynamic massage device having great adaptability to practice massages and that permit substantially reproducing the massage movements performed by professionals.
The invention also proposes a hydrodynamic massage device, comprising a bathtub, injection orifices associated with supply means for producing hydrodynamic jets directed interiorly of the bathtub, and control means for orienting in a synchronized manner the hydrodynamic jets issuing from the injection orifices disposed on opposed lateral surfaces of the bathtub.
According to the invention, this device is characterized in that the control means are provided such that, when they upwardly orient a hydrodynamic jet issuing from an injection orifice disposed on one lateral surface of the bathtub, they simultaneously downwardly orient a hydrodynamic jet issuing from an injection orifice disposed on the opposite lateral surface of the bathtub, and vice versa.
By providing a synchronized adjustment of the orientation of the hydrodynamic jets, the present invention permits adapting the hydrodynamic massage to the particular needs of the patient. The synchronized control of the orientations permits causing the hydrodynamic jets to describe sweeping movements. These sweeping movements generally reproduce the effect of a manual massage, contrary to the known devices in which the hydrodynamic jets remain localized on the same parts of the body. The oriented hydrodynamic jets thus produce the desired massaging rolling contact around the body of the patient.
According to an advantageous embodiment of the invention, each hydrodynamic jet oriented by the control means remains substantially parallel to a respective vertical plane inclined relative to the longitudinal direction of the bathtub, such that the hydrodynamic jets are oriented interiorly of the bathtub and towards the side where in use is situated the head of the patient stretched out in the bathtub.
The hydrodynamic jets thus ascend from the feet toward the head of the patient, with a sweeping motion parallel to the inclined vertical plane. Upon contacting the body of the patient, they thus produce a massage which compensates the muscular forces opposing gravity.
