Definitions
- the invention relates to an apparatus for massaging parts of the body, by sequential cyclic pressures making it possible to provide drainage along the part or parts treated. It extends to a distributor intended to equip said device.
- massage devices which include a treatment accessory (waders, abdominal belt, etc.) which is called upon to be placed in contact with a part of a patient's body in order to carry out a succession of local compressions thereon. progressing in the direction of the lymphatic drainage to be performed.
- This accessory is generally composed of a plurality of juxtaposed inflatable cells which are successively inflated, then deflated according to a defined cycle.
- the massage accessory surrounds the member to be treated and its inflatable cells are connected by a bundle of ducts to an air distribution installation comprising in particular a rotary distributor or with drawers or a plurality of solenoid valves, this installation being able to successively deliver the pneumatic pressure to each cell through the duct which is associated with it.
- an air distribution installation comprising in particular a rotary distributor or with drawers or a plurality of solenoid valves, this installation being able to successively deliver the pneumatic pressure to each cell through the duct which is associated with it.
- the present invention proposes to considerably simplify massage devices of the type mentioned above and to provide a massage device having a reduced number of conduits and much simpler distribution means, while being able to work cyclically at low pressures. required by the massage action (of the order of 50 to 100 millibars).
- Another objective of the invention is to provide a device which allows, in a very flexible manner, an adjustment of the characteristics of the massage (value of the pressures, speed of the drainage, amplitude of the pressure wave, etc.).
- the device only comprises an inflation duct and a control duct.
- the control duct receives the control pressure Pc before the inflation fluid is distributed: the downstream orifices of all of the distributors are then closed since the control pressure Pc prevailing at these distributors is greater than the local pressure inflation (relative inflation pressure zero before distribution of the inflation fluid).
- the inflation fluid is distributed at the pressure Pg, the first cell swells at excluding others who are isolated by distributors; when, at this first cell, the local inflation pressure reaches a pressure equal to K.Pc, the distributor associated with said first cell opens and the inflation fluid is distributed to the second cell.
- the cells are thus swollen, ensuring a drainage of the body from the areas in contact with the first cell to the areas in contact with the last.
- the control unit then ensures the closing of the solenoid valves and the deflation of the cells, the operation continuing cyclically.
- the structure of such an apparatus (and in particular that of its distributors) is adapted to operate at low pressures suitable for performing massage operations.
- the coefficient K which depends on the geometry of the distributor will generally be chosen greater than 1 but may also be equal to or less than 1. It may be different from one distributor to another.
- treatment accessories can, if necessary, be arranged in series in order to be inflated successively, for example a thigh-high and an abdominal belt.
- accessories can be arranged in parallel so that their cells are inflated synchronously, for example two waders intended to be applied around the two lower membranes.
- the invention can be applied regardless of the type of accessory: accessory with cells located end to end, accessory with cells arranged in scales ...
- Such distributors of very simple structure are inexpensive and space-saving and can be secured without difficulty on the inflatable cells.
- the massage device shown by way of example in the figures essentially comprises a massage accessory 1 adapted to be applied around a leg, an inflation duct 2 and a control duct 3 extending along and close to the massage accessory 1, a plurality of distributors such as 4 interposed on these conduits and secured to the massage accessory, and a sequential compressed air distribution unit 5.
- the massage accessory 1 is in particular of the type described in FR patent No. 85.09764, comprising two flexible walls 6 and 7 which are joined together to form several juxtaposed housings in which are sealed inflatable pockets 8 in one elastic material.
- the shape of the set of cells thus formed is adapted to be able to close around the member to be treated and to conform to the contours of the latter, straps 9, strips or equivalent means (partially shown) being provided for maintaining the accessory around the member.
- any other type of accessory can be provided in the device of the invention (in particular accessory with cells arranged in scales).
- the accessory can simply consist of two locally welded walls to form the cells.
- the distributors 4 are, in the example, arranged in alignment with one another in the vicinity of a longitudinal edge of the massage accessory 1.
- a distributor 4 is attached to each cell 8 so as to allow inflation thereof. As illustrated in FIGS. 3a and 3b, these distributors can in particular be sealed on one face of the inflatable cell; in the example, this attachment is achieved by means of a reinforcement piece 34, called a nipple, which is glued to the flexible wall of the cell.
- This pacifier has a housing with an enlarged head 34a into which an inflation nozzle 13 of the distributor is snapped into place.
- Each distributor 4 in the general shape of a T is in the example composed of a hollow body 33 which delimits a compartment 10 and comprises three tubular branches: an upstream branch 11, a downstream branch 12 situated in alignment with the upstream branch, and an inflation branch 13 orthogonal to the other two, located opposite the compartment 10. These branches are molded in one piece with the body 33 (if necessary they can be attached and glued therein).
- the compartment 10 is surmounted by a sealed cover 14 which in the example is screwed into the body 33 so as to close the compartment 10.
- This cover 14 is provided with means for connecting the control conduit 3, constituted by two male junction tips 15 and 16 situated substantially in alignment with one another. These end pieces are molded with the cover 14 (or, if appropriate, attached and glued therein). The cover 14 is pierced with a channel 14a so that the pressure Pc of the control fluid is established in the compartment 10.
- the latter contains a flexible membrane 17 made of elastomer or other material of the same type, the edges of which are tightly pinched in the compartment 10 when the cover is screwed on.
- This membrane 17 separates the compartment 10 into two chambers 10a and 10b: it is subjected on its upper face to the pressure Pc of the control fluid which prevails in the chamber 10b and on its lower face to the local pressure of the inflation fluid which prevails in room 10a. If necessary, this membrane can be subjected to external forces exerted either by a damping system, or by a spring system, in particular to avoid vibrations.
- the upstream tubular branch 11 forms a male junction end (delimiting the upstream orifice 11a) and communicates with the secant inflation branch 13 which itself forms a male junction end (delimiting the inflation orifice 13a).
- These two branches 11 and 13 open into the chamber 10a of compartment 10 by a lumen 18a surrounded by a bearing surface 18 for supporting the membrane.
- the downstream branch 12 forms a male junction end (delimiting the downstream orifice 12a) and is isolated from the first two: it communicates with the chamber 10a by a light 18b located at the periphery of the bearing surface 18.
- the inflation duct 2 is connected to the branches 11 and 12 (the inlet located on the side of the distribution unit being connected to the upstream branch 11 and the outlet located on the opposite side being connected to the downstream branch 12).
- the control duct 3 is itself connected to the connection ends 15 and 16.
- the membrane 17 When the membrane 17 is applied against the bearing surface 18, it is subjected, on the one hand, to the local inflation pressure on a section s (defined by the bearing surface 18), on the other hand, to the control pressure Pc on a section S (corresponding to the diameter of the membrane).
- the S / s ratio is designated by multiplier coefficient K.
- the distributor When the control pressure Pc is established in the chamber 10b, the distributor remains in the closed state as long as the local inflation pressure prevailing in the branches 11 and 13 remains below K.Pc (FIG. 3a). In this position, the membrane 17 is supported on the bearing surface 18 and the downstream branch 12 is isolated from the upstream branch 11 and inflation branch 13: the inflation fluid is not transmitted to the cells located downstream.
- the membrane 17 deviates from its range and opens the communication to the downstream branch 12 (FIG. 3b).
- the inflation fluid is delivered to the next cell. The inflation is thus carried out step by step from the first cell of the massage accessory to the last.
- the inflation pipes 2 and control pipe 3 are connected to the unit 5 comprising means for distributing the inflation fluid and means for distributing the control fluid.
- a compressor 19 supplies high compressed air presses a reservoir 20 fitted with a safety valve 21 and a control pressure gauge 22.
- the reservoir 20 is connected to a pneumatic inflation line 23 and to a pneumatic control line 24.
- the inflation line 23 to which the inflation duct 2 is connected essentially comprises an adjustable pressure reducer 25 reducing the pressure to an inflation pressure Pg, a solenoid valve 26 in the example of the three-way type to allow venting free from the inflation duct 2, a flow limiter 27 and a control pressure gauge 28.
- a buffer tank 35 can be provided on this inflation line in order to dampen the inflation of the first cells, in particular when these these have a lower volume, as is the case for a thigh piece extending at the level of the foot; this reservoir 35 can if necessary introduce the inflation delay time mentioned below.
- the inflation duct 2 is open at its end 2a located downstream of the last inflatable cell so that the deflation takes place at the end of the sequence by this end and by the solenoid valve 26.
- the deflation can if necessary be obtained differently, in particular by a special solenoid valve.
- the control line 24 to which the control duct 3 is connected essentially comprises an adjustable pressure regulator 29 reducing the pressure to a control pressure Pc ⁇ Pg, a solenoid valve 30 of the three-way type to allow the venting of the air control line 3, and a control manometer 31.
- the control conduit 3 is closed at its end 3a located downstream of the last inflatable cell so that its pressurization ensures a stable establishment of the control pressure Pc.
- the solenoid valves 26 and 30 are electrically slaved to an electronic control unit 32 adapted to cyclically control the opening and closing of these (that is to say the pressurization of the conduits 2 and 3, and their setting outdoors) ; the unit 32 is adapted to impose a delay time on opening at the solenoid valve 26 so that the control pressure Pc is established beforehand in the control conduit 3 and the chambers 10b of the distributors.
- the duration of the closing / opening cycles and the duty cycle are adjusted according to the nature of the massage to be performed.
- the adjustment of the outlet pressure of the regulator 25 (inflation pressure Pg) and outlet pressure of the regulator 29 (control pressure Pc) makes it possible to adjust the characteristics of the compression wave which ensures lymphatic drainage (the drainage speed , that is to say the speed of displacement of the pressure front from one cell to another, as well as the amplitude of this pressure front are functions of the difference Pg - K.Pc).
- control duct 3 is depressurized and the cells deflate through the open end of the duct 2a and by the solenoid valve 26.
- the duration of the inflation sequence exceeds the time necessary to inflate all the cells, the air will escape through the last distributor which then behaves like an exhaust valve, the pressure can never exceed the control pressure. If the duration of the inflation sequence is less than the time necessary for the inflation to reach the last cells, these will not be inflated: it is thus possible to inflate only a fraction of the massage accessory, the number of uninflated cells can be adjusted by adjusting the duration of the inflation sequence.
- the range 18 of the various distributors 4 may have a different diameter: by adjusting the section -s- of the various distributors, the multiplier coefficient K can be varied from one distributor to another; the cells can thus be brought to undergo different inflation pressures (K.Pc), all the higher the coefficient K of the cell considered will be higher.
- the invention makes it possible to perform massages at differential pressures adapted to the areas of the body to which the cells apply.
- the inflation order of the cells depends on the order in which they are connected to the inflation duct 2. This order may be the order of geometric succession of these, but it may also be different.
