Definitions
- the present invention relates to a hydraulic device for massage and lymphatic drainage of the human body.
- the technical sector of the invention is the field of manufacturing massage devices using hydraulic pressure.
- One of the main applications of the invention is the production of sleeves having, for example, the shape of a member and which can therefore be put on it, in order to be able to massage it by intermittent pressure transmission along its area.
- the problem posed is in fact to be able to transmit a wide variety of pressure ranges on any part of the surface of the body according to profiles of variation of this pressure adapted to each specific case, according to the desired result, which are controllable and repetitive , without complex means of implementation, and which best reproduce the effects of a manual massage by waves of progressive pressures and whose average amplitude decreases in the direction of propagation of this wave.
- a hydraulic device for massaging and lymphatic drainage of a part of the human body comprising at least one enclosure capable of covering said part of the body, and in which a fluid circulates in the direction of the desired massage, and at a variable pressure "p", said enclosure being locally deformable under the sole effect of said pressure "p", and such that the fluid circulates therein undergoing a given pressure drop in each zone of said enclosure, linked in particular to the flow rate and the pressure of the fluid at the inlet of said enclosure.
- said enclosure is filled with a porous medium of given reduced permeability, determined as a function of the section of the circulation volume of the fluid; in another embodiment, said fluid is a high viscosity fluid, fixed as a function of the section of its circulation volume in the enclosure and of its adhesion against the walls along which it circulates; in another embodiment, the external walls of the assembly are permeable to said fluid, and in other embodiments, two or three of the above modes are combined.
- the outer wall of the enclosure is voluntarily deformable externally, by any means, in order to modify the section of the internal volume of circulation of the fluid at given points.
- a device which includes pressure sensors inside said enclosure, connected to an external central unit, which compares said recorded pressures with reference values, determined beforehand as a function of the type of massage desired, and which allows the regulation of the flow rate and the pressure, at the entry of the fluid into the enclosure to obtain said set values.
- the present invention is based on the known hydraulic principle of the pressure losses produced in the direction of circulation of a liquid, gaseous, more or less viscous fluid, flowing in a medium with more or less reduced permeability according to said viscosity of the fluid.
- the device according to the invention makes it possible to apply this hydraulic principle to massage techniques of the human body, by controlling these pressure drops, in order to obtain on the part of the body concerned a variable and linearly decreasing pressure in the desired direction, and the very principle allows a very large variation of the effects.
- this modification of walls can be adjusted for each case, or can even be modulated during operation, with in combination, a possible modification of the inlet pressure and the flow rate of the fluid , pressure profiles are no longer only degressively linear on average, but also along any curve that may be desired.
- an envelope on any part of the body can thus transmit a large amount of pressure effects, whether they are very light such as touch, sliding, drainage etc. or very strong as for massages, and following any desired profile and frequency, allowing very broad action techniques, both superficial and deep on the part of the body considered, with a view to lymphatic drainage, improvement of blood circulation, etc.
- the entire circuit is controllable, thus ensuring reliability and repeatability of actions, while requiring only a simple and light implementation.
- Figure 1 is a sectional view of part of the device on a lower member.
- Figure 2 is an example of pressure curves.
- Figure 3 is an overall diagram of the device.
- Figure 4 is an embodiment of an enclosure according to the invention.
- Figure 1 is a sectional view of a portion of the device installed for example on a lower limb and therefore surrounding the entire calf of a person by a circular enclosure 2 closing around it, and a length "1" which may cover from the ankle to the base of the knee, but may be shorter or also longer length by covering the upper part of the leg.
- the hydraulic device according to the invention for the massage and the lymphatic drainage of this part 1 of the human body comprises an enclosure 2 which can cover said part of the body and in which a fluid 3 circulates in the direction of the desired massage and at a pressure "p "variable.
- this fluid enters through an inlet 5 located at the base of the device, ie here towards the patient's ankle; said inlet 5 can be of any type, seals around said dowel and is connected to any system for supplying said fluid; it then emerges at the upper part of the device, either here towards the base of the knee via an outlet 6, itself ensuring sealing at this level there, or is open in the ambient environment if the fluid allows it, is connected to any circuit, as shown in Figure 3. ensuring the circulation of the fluid.
- said enclosure 2 is locally deformable under the sole effect of said pressure "p", so that this pressure is controllable and can act directly on the limb or part of the body concerned 1; but this does not mean that the enclosure is generally non-deformable, since it is certain that the external wall can be relatively flexible and therefore uniformly deformable in a controllable manner in the transverse direction of the circulation of the fluid, under the overall effect of pressure ; the fluid 3 circulates in the enclosure in a laminar mode undergoing a pressure drop given in each zone of said enclosure 2 as a function of the flow rate and / or of the pressure of this fluid at the inlet 5-
- This pressure drop can be caused either because said enclosure 2 is filled with a porous medium 4 with given reduced permeability determined as a function of the cross section of the circulation volume of the fluid 3. or because said fluid 3 is of high viscosity and fixed as a function of the section of its circulation volume in the enclosure 2, and of its adhesion against the walls along which it circulates, either with a porosity and permeability of the external wall 7 of the enclosure itself, which then allows fluid to escape through a distributed porosity or through orifices provided 19 at particular points, or over wider areas, according to a distribution circular or not, either by a combination of two or three possibilities to create any desired pressure drop.
- Said porous medium 4 may consist of solid or hollow bubbles, grains of fibrous tissue sand, foam, micro tubes, laminated layers, any particles chosen according to the mechanical characteristic and the desired permeability.
- the pressure "p” is transmitted to the part of the body 1 either directly by immersion or covering of said member or part of the body by the enclosure 2 filled or not with said medium 4 or, in another embodiment, said enclosure 2 comprises a quasi-rigid external wall 7 and a flexible internal wall 8. This then covers said part of the body 1, to which it transmits the pressure "p" of the fluid 3 through its surface which only transmits and which thus isolates the skin of the person from the 'fluid which circulates in said enclosure.
- the external wall 7 of the enclosure 2 is pre-molded to the shape of the part of the body 1. It can be personalized, relatively flexible, but while remaining rigid enough not to be deformed locally by said pressure, but flexible enough to absorb possible overpressures and allow finer adjustments to the limb's morphology.
- This external wall 7 is either impermeable to the fluid circulating inside the enclosure, or permeable in a controllable manner to create an additional pressure drop effect when the fluid is compatible with the external medium, or impermeable on the most of its surface and open at particular points 19 and whether or not connected to an external circuit.
- Figure 2 is an example of a pressure curve that can be obtained with the device according to Figures 1 and 3-
- the ordinate represents the pressure "p" prevailing at any point of said enclosure 2 and the abscissa the position of said point along the length "1" of said enclosure: the origin corresponds to the inlet 5 of the fluid in said enclosure, and the end of the curve is at the outlet of said enclosure 6; the curves shown here correspond to an inlet pressure p0 given to the same cross-sectional configuration of the circulation volume in said enclosure 2, which thus has a given laminar flow of fluid 3 which is constant in this volume.
- the curve 15 can be obtained with a flow of water from a simple tap through a polyethylene foam: one can thus obtain an inlet pressure of 1.8 bar for an outlet pressure of 1.2 bar for a length "1" - of the enclosure of 40 cm, while the curve 18 can be obtained by a drip rate also with water, but with an inlet pressure, for the same polyethylene foam 0.3 bar and 0.15 bar outlet pressure.
- the circulation of the fluid may indeed even be infinitesimal depending on the case.
- mercury tank systems would give a curve (pO, pi) of very marked negative constant slope, related to the density of mercury.
- pO, pi a curve of this type and even even more negative with a device according to the invention, superimposing the three effects of pressure drop: by of course increasing the viscosity, by decreasing the permeability of the internal medium in the enclosure of the device and by escaping the fluid as it circulates through the enclosure.
- the enclosure 2 may include outlet orifices 19 intermediate with the fluid 3. which orifices may be very localized and punctual on specific areas to be treated, by a local pressure variation effect, or cover a wider area, such as along a full turn of a cylindrical enclosure, when the latter surrounds a member.
- These orifices 19 can be connected to an external suction system and even cause local depressions.
- the fluid 3 penetrates, under pressure or not, into the enclosure 2, by its ends 5 "and leaves through the single or several intermediate orifices 19, by vacuum: moreover , when said enclosure 2 is placed on a surface without going around a complete part of the body, the ends 5.
- the fluid 3 thus circulates from the median zones of said enclosure towards the ends, and undergoes a pressure drop therein, to ensure the desired effect of pressure variation on the part of the body to be treated, as in all the device configurations mentioned above.
- the main objective is in fact to perform a massage, thanks to the essential characteristic of the invention, which is to circulate a fluid 3 in an enclosure 2 in the direction of the desired massage, according to a variable pressure "p", undergoing a given pressure drop, according to the various possibilities described above in each zone of said enclosure 2, linked in particular to the flow rate and the pressure of the fluid at any entry into said enclosure. It can therefore have various forms with one or more inlets and one or more outlets defined according to the type of massage and the part of the body to be treated.
- Figure 3 is an overall diagram of said device schematically showing the enclosure 2 of Figure 1; the part of the member of the human body which one wishes to massage or drain being represented by a simple rectangle 1 undergoing the pressure or the depression transmitted by the fluid 3 inside the volume 4 of said enclosure 2.
- the external wall 7 of this enclosure 2 is shown here as being capable of being externally deformable by any mechanical or hydraulic system 14 of modifications to the shape of said wall 7 by reducing at certain points the cross-section of the internal volume of circulation of the fluid 3 at given points.
- the device may also include a compressor or a hydraulic pump 11 circulating said fluid 3 through flow control valves 12 at the inlet and at the outlet of enclosure 2, in order to obtain the desired values of flow , pressure at the inlet 5 and / or possible vacuum at the outlet 6, and / or pressure or depression in the orifice (s) 19-
- all of the control valves 12 and the circulation pump 11, as well as said enclosure modification systems 14 are connected to a central unit 10 external: from sensors of any type 9 of pressures located at different points pi inside said enclosure 2, the latter compares the pressures recorded by said sensors with reference values determined beforehand, according to the type of massage and desired drainage, and allows, by command to modify the parameters of the regulation valves 12 and of the circulation pump 11, to adjust the necessary flow rate, which can be measured itself by a sensor 13 located in the pumping circuit of said fluid 3-
- the circuit can be open on the external environment at the outlet 6 of the massage enclosure 2: in this case for example, the compressor or pump 11 can be an air compressor sucking the latter into the atmosphere, the air then being released there after his massage "work"; similarly in use in a basin or swimming pool, it can be a hydraulic pump 11 which takes its fluid in this basin or swimming pool, where the person can be installed, said fluid also returning therein after it has passed through the enclosure 2 .
- the compressor or pump 11 can be an air compressor sucking the latter into the atmosphere, the air then being released there after his massage "work”; similarly in use in a basin or swimming pool, it can be a hydraulic pump 11 which takes its fluid in this basin or swimming pool, where the person can be installed, said fluid also returning therein after it has passed through the enclosure 2 .
- This enclosure can also be a simple combination of diving equipment type directly donned on the part of the body concerned.
- each of these enclosures which can be produced according to one of the embodiments described above, with one or more inlet openings, one or more outlet openings, at the ends of the enclosure and / or distributed along its walls, and this without leaving of the scope of the present invention.
- FIG. 4 is an exemplary embodiment of an enclosure 2 of a device according to the invention, produced from an envelope which can be wound around the part of the body to be treated 1, with an overlap of the ends, on the one hand to ensure continuity of contact with the surface of the body, and on the other hand, to ensure the closure 20 by any suitable system, such as two ribbons, each fixed along the edge of each end and woven differently so that their surfaces grip by contact in the desired position which can therefore be adjustable, such as the so-called "VELCRO" closures, or by an independent outer casing.
- any suitable system such as two ribbons, each fixed along the edge of each end and woven differently so that their surfaces grip by contact in the desired position which can therefore be adjustable, such as the so-called "VELCRO" closures, or by an independent outer casing.
- Such a form of winding device allows a perfect adjustment of its internal volume to that of any part of the body 1 to be treated, thanks in addition to a conical shape and / or molded in shape according to the general shape of said part 1. , and a cover without wrinkles.
- the outer wall 7 of the envelope can be made of polyurethane or latex, and the inner part 4 of polyester foam for example.
- the fluid is then brought to the narrowest conical part, placed towards the end of a member for example, by single or multiple inlets "and is evacuated by a single, or also multiple outlet, 6, in the upper part widest conical.
- Such an enclosure thus meets the characteristics of the invention by allowing the application of a permanent and measurable pressure gradient, without having any displacement of the solid parts that are the walls, but simply by virtue of a flow specific of the fluid between the inlets 5 and the outlets 6.
- the circulating fluid in fact directly undergoes the pressure gradient by continuous pressure drop along any path inside the enclosure 2: there is an obstruction in the flow of the fluid inside it, either by the high viscosity of the fluid used, or by the presence of a porous medium inside this enclosure 2 as described above, or by a combination of these two criteria.
- a high viscosity fluid any fluid having a viscosity greater than that of water.
- the means known to date actually use the fluid, which is often either gas or simply water, as a means of transmitting a pressure caused from the outside at a given time to mechanical systems which , attempt to massage by varying the pressure, which they receive transmitted by the fluid from the outside, over time and / or with an action restricted or limited to one section: the pressure gradient is therefore never exists at any given time or it is very coarse in separate compartments; indeed, in one case there is a pressure control in stages in compartments, and in the other, there is stealth transmission of pressure waves in the direction of small pipes or through flexible walls.
- any enclosure of the device according to the invention in any enclosure of the device according to the invention, it is the positions of the inputs and outputs of the fluid which impose the direction of circulation and thus the direction of application of the gradient on the surface of the part of the body 1 to be treated: there is a spatial distribution of the pressure which is of prime interest for application to the venous or lymphatic network in the main application of the present invention.
- the present invention also makes it possible to simulate the immersion of a member in water or in a liquid of any density.
