Description Title of the invention: Improved compression system for a part of a living being Technical field of the invention

[0001] — The present invention relates to a system for compressing a part of a being living. The system is particularly suited to treating pathologies such as the lymphedema. State of the art

[0002] — The treatment of a pathology such as lymphedema is carried out using a A compression system that wraps around the limb being treated. There are several systems available. which are said to be passive, like those described in the patent application US2015 / 366720A1, and which use a simple multi-ring clamping sleeve whose compression levels are manually adjusted using straps. And there are active treatment systems. Among the active systems, some use a pneumatic solution like the one described in US patent 6406445B1. The system then consists of several rings placed side by side along the sleeve, Each ring consists of a pneumatically operated tube. The installation... The operation of a sequence allows one or more airbags to be inflated in a suitable manner. to circulate lymphatic fluid.

[0003] Among active systems, there are also those that use actuators with Shape-memory alloy distributed along the sleeve. By heating, a wire made in this alloy it contracts. By controlling each actuator individually- By dualizing the system, localized compression can be applied. Such systems active compression methods are described, for example, in patent applications no. US2016 / 074234A1 and US2017 / 304136A1, as well as in patent US5997465. This The latest US patent, US5997465, establishes the principle of using memory alloys. form in compression systems. Patent application US2016 / 074234A1 proposes, in addition to the compression principle, with memory alloy actuators of shape, to provide thermal energy to improve the processing carried out by the system. Patent application US2016 / 074234A1, for its part, proposes solutions actuator locking mechanisms in the retracted position.

[0004] — Similar solutions are also described in prior documents DE102008003124A1, US015 / 073318A1, US2018 / 24265SA1 and US2018 / 177677A1.

[0005] Patent application WO2020 / 144437A1 describes a solution using also several juxtaposed tightening / loosening units, each unit comprising a plate cut in a specific way to give it a spring function, the A plate is inserted between two free edges of the sleeve. A wire made of a shape-memory alloy is electrically powered to retract and actuate the plate, thus ensuring compression of the limb. The patent application EP1013220A1 describes a blood flow measuring device, which uses an electric motor to tighten a ring, via a pull cord wound around a pulley. This earlier principle, using a motor and a link, has been adopted in lymphatic drainage solutions, as described in US patent application 2021 / 121356A1. In this patent application, the device uses a simple wire pulled by a motor, the wire passing around a guide. The traction of the wire brings together two edges of a sleeve placed around the limb to be treated, thus enabling localized compression of the limb. In the treatment of lymphedema around a limb, it has been observed that current solutions are not always effective in evacuating all the lymphatic fluid accumulated around the limb. Initially, as it accumulates around a limb, the lymphatic fluid spreads evenly around the non-malleable section of the limb, creating a circular or quasi-circular section. To evacuate this lymphatic fluid, the compression device is adjusted around the limb by applying radial pressure. Two operating scenarios can then be distinguished: The limb M to be treated has a non-malleable, quasi-circular section; The limb M to be treated has a non-malleable, non-circular cross-section, by oval or oblong example (typically a human forearm). In the first case of operation illustrated by [Fig.1A], the active compression device 1 exerts radial pressures (represented by the arrows in Figures 1A and 1B) uniformly around the limb (E1), allowing the lymphatic fluid L to be evacuated until the limb M can resume its normal, non-pathological and non-malleable section (E2). In the second operating case illustrated in [Fig. 1B], the active compression device 1 initially exerts uniform radial pressure around limb M as long as the cross-section remains circular (E10). As the lymphatic fluid L is evacuated, the cross-section of limb M decreases until it reaches its non-malleable cross-section (E20). Since this non-malleable cross-section is not circular, the device can no longer exert uniform pressure all around limb M. Indeed, in this case, as the contraction continues, because the radius of curvature is no longer homogeneous around the entire perimeter, the pressure will be greater on areas with a small radius of curvature (where the device has reached a non-malleable zone of the limb) and lower on the areas with a larger radius of curvature. On these latter areas, the pressure applied by device 1 will ultimately no longer be high enough to evacuate all the lymphatic fluid (E30). The known devices therefore find their limits in the treatment of lymphedema of the limbs whose so-called non-malleable section is non-circular, these devices can no longer, after a certain time, allow evacuation of the rest of the lymphatic fluid which has accumulated around the limb. The aim of the invention is to provide a compression system that overcomes the limitations of the prior art. This system offers a solution for evacuating all the lymphatic fluid accumulated around a limb, even when the limb's non-malleable cross-section is not circular. The invention will also find other applications, such as the treatment of lipedema to promote the elimination of fat cells or for sports recovery. Description of the invention This goal is achieved by a compression system for a part of a living being, said part of the living being having an initial section before treatment and a final section, the final section being obtained after a compression treatment and being distinct from said initial section, said system comprising: An active compression device that includes a first sleeve comprising a cross-section, an inner face and an outer face, said sleeve being intended to be positioned around the part of the living being and carrying an active module controlled to exert retraction effects of the cross-section of the first sleeve, Volume compensation means comprising one or more volume compensation elements arranged under the inner face of the first sleeve, and defining a volume compensating at least in part a difference in cross-section between the initial and final sections of the part of the living being to be treated. According to a particular feature, the first sleeve and the active module are able to cooperate with each other to exert inelastic retraction effects on the cross-section of the first sleeve. According to another peculiarity, each volume compensation element is fixed to said first sleeve. According to a particular embodiment, each volume compensation element is inserted between two textile layers of said first sleeve. According to another particular embodiment, each volume compensation element is inserted into a pocket made on the inner face of said first sleeve. According to another particular embodiment, the system includes a second sleeve intended to be positioned against the inner face of said first sleeve, this second sleeve carrying the volume compensation element(s). According to one particular feature, each volume compensation element is presented in the form of a foam element. According to another feature, the foam element is made of one or more materials chosen from polyethylene, ethylene vinyl acetate, polypropylene, polyurethane. According to another characteristic, each volumetric compensation element comprises several superimposed layers and / or several successive sections. According to another feature, the active module comprises several juxtaposed compression modules, each compression module comprising at least one electric motor with an output shaft, and a pull link attached to one end of said output shaft of the electric motor and extending between the electric motor and a first moving part to move said first moving part in translation. According to another peculiarity, each compression module has a second moving part, the first moving part and the second moving part being arranged on either side of a support box in which the said electric motor is housed, a single pull link, attached to the output shaft of the electric motor, extending on one side to hook the first moving part and on the other side to hook the second moving part.

For example, the body part of a living being could be a limb M, but also any other part such as the torso, hand, or trunk. Without limitation, the limb M to be treated could be an arm, a leg, a forearm of a living being, etc. In [Fig. 2], for example, it is a forearm. Among other things, the S system is particularly well-suited for treating lymphedema and activating the flow of lymphatic fluid (L) in the affected limb to facilitate its drainage. As another example, it can also stimulate venous and lymphatic flow to aid recovery after physical activity, and be used in lipedema treatments to promote the elimination of fat cells. In the following description, the S compression system of the invention is described as being adapted to fit a limb of a living being. A member M consists of a succession of cross-sections of varying shapes. Each section has an initial shape S_I before treatment and a final shape S_F obtained after treatment. This final section S_F corresponds to the section of the non-malleable and non-pathological limb and represents the target to be achieved after treatment. In the case of pathology, the limb may be surrounded by a volume of lymphatic fluid, increasing its cross-section, which then corresponds to its initial section to be treated. The objective of treatment is to ensure that the limb transitions from its initial section S_I to its final section S_F. According to the invention, with reference to [Fig. 2], the compression system S comprises: An active compression device 1, controlled to perform a a series of compression / relaxation efforts around limb M using of an active module M_0; this active module M_0 comprises several modules of compression M_1 individuals juxtaposed; One or more elements 70 (which can also be called inserts) of com- volumetric compensation, hereinafter also referred to as means of compensation volumetric, inserted into the system to compensate at least partially for a variation in the cross-section of the limb, between its initial cross-section S_I before treatment and its final section S_F after processing; different inte- integration of these volumetric compensation methods within the system; the volume compensation devices can notably be inserted into a sleeve 7 to be positioned in contact with limb M, under the device compression 1 active; The volume compensation elements 70 are dimensioned to induce a homogeneous radial compression force across the entire cross-section of the limb once the malleable volume (created by the presence of lymphatic fluid L) has been evacuated. To achieve this, the volume compensation elements 70 have geometric and mechanical characteristics that depend on the geometric and mechanical characteristics of the limb M being treated. It should be noted that the principle of the invention can be applied regardless of the architecture of the active compression device used, provided that it is capable of automatically generating compression / release forces around the limb being treated. Below, we propose a particular embodiment of an active compression device 1, but this is to be considered in a non-limiting manner. Active compression device Referring to [Fig. 3], the active compression device 1 is in the form of a sleeve. The sleeve is defined by its longitudinal axis and, when placed around the limb, exerts localized compression / release effects on the limb being treated in radial directions along the limb. According to an advantageous embodiment, the sleeve comprises several parts which are described below. The sleeve may include a first part 10 made of a flexible, advantageously non-elastic material, such as a textile, designed to be placed around the limb and having a first free edge 11 and a second free edge 12 (see [Fig. 3]). The first free edge 11 and the second free edge 12 may include adjustable and complementary temporary fastening means, such as hook and loop fasteners, permanent magnets, adjustable straps, hooks, etc. The two free edges are joined to each other by these temporary fastening means so as to close and hold the sleeve around the limb being treated. The temporary fastening means are advantageously chosen to allow adjustment of the sleeve size when it is placed around the limb. In the attached figures, the first part 10 ([Fig. 3]) is made as a single piece of fabric, cut to the desired shape and size. It should be understood that it could be made from several pieces joined together, either permanently by sewing them together, or temporarily using suitable fastening methods (hooks, hook-and-loop fasteners, etc.). The textile piece It comprises two opposing faces, a first face called the internal face 100 intended to be oriented opposite the surface of the limb to be treated, and a second face called the external face 101, turned outwards. This first part 10 advantageously goes all the way around the limb to be treated. The first part 10 of the sleeve can be made of a textile material, for example a synthetic textile. This textile is advantageously low in stretch (maximum 10% stretch deformation) or even non-stretch (in other words, non-elastic) to effectively transmit the compression force created by the system. As shown in [Fig.3], the sleeve has a second part 20 consisting of the active module M_0 of the system. With reference to [Fig. 4], this active module M_O can be rectangular in shape, with two parallel, opposing edges 200, 201, set apart. Each of the two edges 200, 201 of the active module M_O, for example, attaches to two separate portions of the first part 10 of the sleeve. This active module M_O carries several compression modules M_1, advantageously all identical, juxtaposed along a second longitudinal axis (Y) parallel to the longitudinal axis of the sleeve. Each of these compression modules is configured to exert, individually or in groups, a tension along an axis perpendicular to said second longitudinal axis (Y) and called the clamping axis (X). The active module M_O of the system | is presented as a single unit. It is designed to be assembled onto the first part 10 of the system. Compression module M_1 Each compression module M_1 can be ordered to bring together the two portions of the first part 10 of the sleeve to which it is attached, thus performing a localized ring tightening and compression when the sleeve is placed around the limb to be treated. Each compression module M_1 can be made independently and removable from the rest of the active module M_O. It is intended to provide mechanical action and is advantageously controlled and powered by an electronic control and power supply circuit belonging to the device | and advantageously arranged on a support common to all compression modules. Without limitation, and with reference to [Fig. 5], a compression module M_1 comprises a first support element 30 and a second support element 31, separated from each other and capable of translational movement relative to each other along its clamping axis (X). The relative positions of the first support element 30 and the second support element 31 allow adjustment of the clamping force applied by the compression module M_1. The first support element 30 and the second support element 31 can be produced in the form of two independent pieces. The first support element 30 is fixed on the first edge 200 of the active module M_0. The second support element 31 is fixed on the second edge 201 of the active module M._0, opposite the first edge 200. Thus, when the active module M_0 is attached to the first part 10 of the sleeve, pulling on the first support element 30 and the second support element 31, along the (X) axis, brings the two opposite edges 200, 201 of the active module M_0 closer together. This, in turn, pulls in opposite directions on the two portions of the sleeve along the (X) axis to which these two edges are attached, thereby exerting radial clamping and compression on the limb when the sleeve is fitted around it. Since the first part 10 of the sleeve is made of a low-stretch or even non-stretch textile material, the clamping force exerted by each compression module M_1 is transmitted directly to the sleeve to compress the limb. The first support element 30 and the second support element 31 can each have a body, for example made of plastic material. The M_1 compression module may also include a 32 support housing. The compression module M_1 includes an electric motor 50 which is housed in the said support housing 32. The electric motor 50 has a 500 output shaft. The compression module M_1 also includes a pull link 60 which winds or unwinds by action of the electric motor 50 on the output shaft 500, to ensure the movement of the first support element 30 and the second support element 31. According to this embodiment, the compression module M_1 thus drives the two support elements 30, 31 simultaneously towards each other in compression by means of its electric motor 50. In this embodiment, each support element 30, 31 is configured to allow passage of the pull cord 60. At its first end, the pull cord 60 is fixed to the support housing 32, then it hooks onto the first support element 30, before hooking onto the output shaft 500 of the electric motor 50, via a bearing / bearing assembly. As described above, the pull cord 60 then extends to the second support element 31, positioned opposite it, to hook onto it, before returning to be fixed, at its second end, to the support housing 32. At each support element 30, 31, the pull cord slides freely in a groove 33. When the electric motor 50 is activated, the pull cord 60 slides in the groove 33. Of course, other configurations could be considered. Another configuration would be to have the engine pull directly on each element support without a return mechanism. In its initial position, the pull cord 60 is, for example, almost fully extended on both sides. When the electric motor 50 is activated to compress the module M_1, its output shaft 500 rotates, and the two strands of the pull cord 60 wind simultaneously side-by-side onto the output shaft 500 of the motor 50. The two strands are shortened identically and simultaneously, and the two opposing support elements 30, 31 are brought closer together, enabling tightening. The attachment of the pull cord 60 to the output shaft 500 of the electric motor 50 is thus configured to allow simultaneous pulling on the two support elements 30, 31 arranged on either side, bringing them closer together. Each compression module M_1 advantageously includes a dedicated control unit U_P, enabling control of the basic functions of its electric motor 50, such as its activation, direction of rotation, and speed. Each control unit U_P receives commands, for example, from a control unit UC, common to all modules, this control unit UC belonging to a control and power supply circuit. This control and power supply circuit can be implemented in different variant designs. Advantageously, the control and power supply circuit is common to all the compression modules M_1 of the system and is part of the active module M_0. It can be implemented on an independent control and power supply board 70. This board can be extended along a direction parallel to the longitudinal axis (Y), covering all the modules of the system, allowing them to connect their control unit U_P. The board 70 carries the control unit UC and optionally a battery pack, for example, assembled in a single control and power supply block B. Of course, other embodiments could be considered. By way of example, the control and power supply block B is removable and attached to the control and power supply board 70 by a clip system. The electronic connection is made, for example, by spring-loaded contacts.This allows the control and power supply unit B to be changed in case of battery discharge or to upgrade / improve the control and power supply unit B to a version with more options, for example, to a control and power supply unit B with a touchscreen control panel or wireless connectivity. The electronic control and power supply board 70 may not contain any electronic components and may only serve to connect the unit to the various control units U_P. The control and power supply circuit is advantageously common to all M_1 compression modules and advantageously allows, via the control and power supply card 70, for all compression modules to be linked together. Card 70 may include a dedicated compartment (not shown) for housing the battery and connecting it to the circuit. The battery may also be housed in a separate control unit (see below) connected to the control and monitoring system. The control unit (CU) may include a microcontroller for executing a command sequence to the control units (U_P) of the system's compression modules. The command sequence can be selected according to the pathology to be treated or the recovery program to be applied. During the execution of the command sequence, the compression modules can be actuated individually or in groups of several compression modules. Volume compensation means The treatment of lymphedema is often carried out in two phases: An initial decongestion phase during which all the lymphatic fluid The phatic fluid present around the limb is evacuated; A second maintenance phase during which it is necessary to continue treatment to prevent any return of lymphatic fluid around of the member; From [Fig.1B] already described above, it is understood that the first phase cannot be completed using a conventional active compression device when the limb to be treated has a final non-malleable section of non-circular shape. To remedy this, the system of the invention therefore uses volume compensation means. These are inserted under the active compression device 1 to rebuild a suitable volume to compensate for the volume loss around the limb to be treated, this loss being linked to the evacuation of lymphatic fluid L during the treatment. These volume compensation means advantageously include one or more 70 elements or volume compensation inserts. Each volume compensation element 70 is judiciously positioned beneath the active compression device. Their position is chosen to create a circular cross-section around the final section S_F of the limb, after the lymphatic fluid L has already been evacuated (step E100 in [Fig. 7]). The active compression device of the system can thus continue to exert uniform radial forces around the limb M, even after the lymphatic fluid L has been evacuated. Advantageously, the volume compensation means comprise at least two distinct volume compensation elements 70, separated from each other. For the treatment of a human forearm, we will have, for example, two distinct volume compensation elements, separated from each other, positioned diametrically opposite. In general, the volumetric compensation element 70 is made of one or more materials, so as to be adapted to meet certain constraints: The material(s) must have sufficient hardness to ensure the force transfer from the active compression device 1 to limb M; The material(s) must have a hardness suitable for comfort. porting of the S system around the M member; Advantageously, each volume compensation element 70 must be chosen, in composition, size and / or position, so as not to interfere with venous flow during treatment; it must therefore be able to follow the movement of the limb to be treated. Each 70 volume compensation element can be manufactured according to the patient's anatomy and the stage of edema development. It should be noted that on the same S system, it is possible to use volume compensation elements 70 which are distinct in size, composition, volume, hardness… Each compensation element can take different forms. It can have a constant cross-section along its entire length (along the longitudinal axis of the sleeve) or a variable cross-section along its entire length. Its shape will be adapted to the volume to be compensated. As an example, a compensating element used to treat a forearm may have a constant or variable cross-section over its entire length (see figures 8A to 8C described below). For example, using a firmer material allows for a less bulky volumetric compensation element, making it easier to integrate. However, it can generate more discomfort and disrupt venous circulation. Conversely, a softer material will improve comfort but will be more cumbersome. In some cases, several different materials can be layered to take advantage of each material's characteristics. For example, a soft underlayer in contact with the skin promotes comfort, while a firmer overlayer transfers radial pressure. Each volume compensation element (70) is, for example, a foam element. The foam can be made from one or more materials. Various materials can be considered, such as polyethylene (PE), ethylene vinyl acetate (EVA), polypropylene (PP), and polyurethane (PU), with Shore hardness ranging from SA to 90A. It is possible to use layered composites of several materials based on these different foams or other materials. Volume compensation elements can be manufactured by extrusion, machining, molding, thermoforming, etc. Alternatively, they can also consist of pouches containing gels, liquids, or gases. This would allow for adaptation of the viscosity of the liquid used or to adjust the pressure of the injected gas, according to the volumetric compensation to be provided and the desired hardness. Figures 8A to 8C described below show some examples of implementation of compensation elements usable within the framework of the invention. Figure 8A shows a volume compensation element 70 for a forearm, made of two superimposed layers 700, 701, for example of different materials and / or different densities, as described above. The compensation element has a variable cross-section along its length. Figure 8B also shows a compensation element 70, also for the forearm, made of several successive sections 702, 703, 704 assembled along the longitudinal axis (Y). Similarly, the materials and / or densities can vary according to the sections. Figure [8C] shows another example of the realization of the compensation element 70 for one hand, made in two successive sections 705, 706. The sections and / or layers can be adapted: Sized according to the size of the limb to be treated: In number / volume depending on the size of the limb and the compensation volumetric to be applied; In terms of material type; In hardness / density; In number of layers / sections; With reference to figures GA and 6B, two integration solutions can be proposed. In [Fig.6A], the volume compensation elements 70 are integrated into the sleeve of the active compression device 1. Each volume compensation element 70 can be inserted between two layers of the first textile part 10 of the sleeve of the active compression device 1, for example by lamination. It can also be inserted into a dedicated pocket created on the inner surface 100 of the sleeve of the active compression device 1. It can be attached to this inner surface 100 of the sleeve by any known conventional means, such as hook and loop fasteners or adhesive. Some solutions have the advantage of making the element 70 removable, allowing, for example, its replacement with an element of identical or different structure (different stiffness, different size). In [Fig. 6B], the compensation means are integrated into a specific sleeve 7, separate from that of the active compression device 1. This sleeve 7, made of a textile material, is positioned around the limb M to be treated, in direct contact with it, and is intended to be covered by the sleeve of the active compression device 1. In the case where limb M is a forearm, it may include a thumb loop 71 facilitating its positioning. Figure 2 illustrates the principle of setting up the system around a human forearm. The volume compensation means are arranged on a textile sleeve 7 equipped with a thumb loop 71. The active compression device 1 is then placed over this sleeve 7. It should be noted that the S compression system of the invention allows for targeted compression actions. The volume compensation means are associated with an active compression device, controlled to generate an advantageously inelastic or slightly elastic retraction of its cross-section, thus enabling optimal force transfer. It is understood that the presence of volume compensation means will allow for a modification of the radial compression principle of the limb, radial compression normally being achieved by the active compression device 1 alone. Figure 7 better illustrates the operating principle of system S on a limb M having a non-malleable, non-circular cross-section (for example, oval in shape). Limb M could be, for example, a forearm. E100: The lymphatic fluid L creates an initial circular section around the limb M. System S is adapted around the section thus generated (non-malleable section + lymphatic fluid L). The system uses two volume compensation elements 70 positioned symmetrically on either side of limb M. The active compression device 1 is positioned around the volume compensation elements. It is controlled to exert compression effects on limb M. At this stage, it should be noted that it would be possible to dispense with the volume compensation elements because lymphatic fluid L remains present all around limb M and the non-malleable section of the limb has not yet been reached. E200: Because limb M has a non-malleable, non-circular cross-section, the active compression device 1 comes into contact with the areas of limb M where the radius of curvature is most pronounced. Without volume compensation, the active compression device 1 would then lose its effectiveness in evacuating the remaining lymphatic fluid L accumulated around limb M (see [Fig. 1B]). The volume compensation elements 70 are positioned to rebuild sufficient volume around limb M (defined by its non-malleable cross-section and the volume of lymphatic fluid L still present around limb M and remaining to be evacuated), so that the active compression device 1 retains its effectiveness. E300: In conjunction with the active compression device 1, the volumetric compression means enabled the evacuation of all the lymphatic fluid L accumulated around limb M. It is observed that, in an ideal configuration, the volume compensation elements 70 must have a geometry that allows a circular cross-section volume to be reconstructed around the non-malleable section (section S_F) of limb M (i.e., in the absence of lymphatic fluid). It should be understood from the description in [Fig. 7] above that the reasoning for a particular section of a limb can be extended to adjacent sections along the entire length of the limb being treated. And as indicated above, each volumetric compensation element can be adapted to the shape of the limb being treated and to the evolution of the pathology. The principle of the invention remains to provide volumetric compensation. This compensation can be achieved with one or more compensation elements, identical or not, of various shapes. The solution presented by the invention offers numerous advantages, including: A simple solution to allow lymphatic fluid drainage regardless of the morphology of the limb to be treated; A solution that works with different device architectures active compression; A solution easily adaptable to the morphology of the limb being treated and which is evolving depending on the progress of the treatment;
