  • this suction drives the whole of the second valve 30 towards the center of the internal chamber 4 by pivoting around the pivot axis 18, up to a so-called closed extreme position, then the reduction in the intensity of the suction allows the second valve to return to its open position under the effect of the return spring 33.
  • the creation of cycles suctions by a variable suction amplitude thus induces beats of the second valve 30. These beats also depend on its interaction with the skin of a patient. In addition to these beats, the roller continues its predefined rotation, independently of the suction or the position of the support part 31.

  • This aspiration creates a depression within the internal chamber, which makes it possible to form the skin fold.
  • the resulting massage therefore partly depends on the skin fold formed.
  • all the air leaks modify the suction effect of the massage device, making this suction variable, unpredictable and of reduced intensity, which has a degrading effect on the massage performed.
  • the main problem of sealing arises at the level of the lower opening 3 of the internal chamber 4, since this opening has the largest surface, and since it cooperates with the valves which are mobile.
  • the figures 10 and 11 precisely illustrate the operation of the massage head described above, positioned within a massage device, which is not shown to simplify the figures.
  • the lower surface 2 of the massage head is positioned in abutment on the skin 10 of a patient.
  • the lower ends of the two respective active parts of each valve 20, 30 protrude very slightly below the lower surface 2 to come into contact firstly on the patient's skin for performing the massage, by participating in the formation of a skin fold 11, in addition to the suction generated by the massage device.
  • a skin fold 11 is thus created within the internal chamber 4 of the massage head 1.
  • the active parts of the two valves remain in contact with the skin at the level of the skin fold 11 to carry out the programmed massages.

  • the two active surfaces 21, 39 of each valve 20, 30 respectively come into contact with the patient's skin.
  • they are positioned so that their lower end protrudes slightly, by approximately 1 mm, below the lower surface 2 of the bell 40 of the massage head. This excess is preferably between 0.5 and 2 mm.
  • the lower surface 2 of the massage head has a shape such that its four surfaces 12, 13, 14, 15 which completely surround the lower opening 3 come into contact with the patient's skin.
  • This closed contact of the lower surface 2 of the valve on the patient's skin provides a first seal.
  • the front 12 and rear 13 surfaces are rounded, as previously described, which makes it possible to modify the inclination of the massage head during its use, without discomfort for the patient and without interrupting the contact with the skin and the aforementioned tightness .
  • each valve 20, 30 also perform a sealing function between the valves 20, 30 and the internal wall of the internal chamber 4. Indeed, the proximity of these surfaces forms a baffle and minimizes the space available for the passage of air.
  • each valve 20, 30 has a continuous and closed surface between its lowest lower end and its respective pivot axis 17, 18, in the upper position of the internal chamber, which prevents any circulation of air between the walls of the internal chamber and the valves towards the central part of the internal chamber 4.
  • valves of the mechanized type and of the roller type.
  • the massage head could use two mechanized valves, identical or not, or two roller valves, identical or not. More generally, the concept of the invention can be implemented with any valve.
  • the invention also relates to a massage device which incorporates such a massage head.
  • a massage device which incorporates such a massage head.
  • Such a device therefore comprises a connecting means which allows the securing, preferably removable, of the massage head to the rest of the device.
  • a massage device further comprises a suction device, connected to the internal chamber 4 of the massage head 1 via the connecting elements arranged at the level of the connecting opening 43 of the massage head.
  • Such a massage device further comprises a control unit, which for example comprises a computer, which controls the suction and possibly the movements of at least one valve.
  • This control unit can include any hardware (hardware) and software (software) means.
  • the massage device also comprises a gripping part for its manipulation by an operator. It also includes a man-machine interface allowing its start-up and possible settings of its mode of operation.
