Description

[0001] Therapeutic aid for a body part

[0002] The invention relates to a therapeutic aid for a body part.

[0003] Therapeutic aids are known in various forms, for example in the form of a support or compression stocking, a bandage, an orthosis, or the like. The body part to be covered with the aid can be a foot or ankle, a lower leg, a knee joint, an entire leg, a wrist, a forearm, an elbow joint, an entire arm, or the like. The therapeutic aid is attached to the body part in a suitable manner in order to exert the therapeutic effect on the body part when worn.In the case of a compression stocking, bandage, or orthosis, for example, the therapeutic effect is virtually constant or static; it results from the compressive properties of the compression stocking or bandage, possibly with an integrated pad, or the geometry or, if applicable, the flexible design of an orthosis, etc. It is not possible to influence or adapt these properties before or during wearing the device.

[0004] The invention is based on the problem of providing an improved therapeutic aid.

[0005] To solve this problem, the invention provides a therapeutic aid for a body part, comprising an at least partially textile carrier and a pressure generating device which comprises at least one first fluid chamber arranged on the carrier or at least one first fluid chamber located externally to the carrier and at least one second fluid chamber arranged on the carrier, wherein the two fluid chambers are fluidically coupled in such a way that upon compression of the first fluid chamber, the fluid located therein is displaced into the second fluid chamber, increasing the pressure in the second fluid chamber, which stiffens and / or deforms as a result of the pressure increase. The therapeutic aid according to the invention has, on the one hand, an at least partially textile carrier, i.e. a section which consists of a textile such as a knitted or warp-knitted fabric or the like.Furthermore, a pressure generating device is provided in the form of a fluid chamber system, comprising at least a first and at least one second fluid chamber. The first fluid chamber can be arranged either on the carrier, for example - with regard to the carrying position - on the outside of the carrier, on the inside of the carrier or integrated in the carrier between two carrier layers; alternatively, it can also be arranged externally to the carrier and coupled or coupleable to the carrier via a suitable fluid line. The at least one second fluid chamber, on the other hand, is always arranged on the carrier, again either on the outside of the carrier, on the inside of the carrier or integrated in the carrier between two carrier layers. This second fluid chamber is coupled via a suitable fluid line to the first fluid chamber, which is also arranged on the carrier or externally to the carrier.The function of this fluid chamber system is such that by increasing the pressure on the first fluid chamber, for example by pressing on the fluid chamber, it is possible to guide the fluid in the first fluid chamber via the fluid line into the second fluid chamber in order to increase the pressure in the second fluid chamber accordingly. Since the second fluid chamber is necessarily on the wearer, which in turn is arranged adjacent to the body part to be treated, this increase in pressure in the second fluid chamber can accordingly increase the pressure exerted on the affected body part. Thus, the therapeutic properties of the aid can be changed by an increase in pressure that can be achieved, for example, in the worn position. This means that the body part can be influenced in a different way than in the basic design of the aid.

[0006] This provides the person using the aid with the simple possibility of specifically setting and adjusting the pressure in the second fluid chamber and thus the pressure exerted on the body part by the support section provided on or in which the second fluid chamber is provided, or even changing it cyclically if necessary, by actuating the at least one first fluid chamber or by compressing it. This is because the integrated fluid chamber system allows a local variation of the pressure or compression exerted on the body part via the aid or the textile support.A variable "pressure" is understood not only as a pressure that is applied quasi-radially to the body part, for example, the leg or arm, but also as a pressure that is generated, for example, by stiffening the second fluid chamber under increased pressure, and which stiffens the aid locally, so that, through this stiffening, for example, a movement of the body part is either limited, hindered, or prevented by the aid, or even supported. This means that the change in pressure can influence the therapeutic properties of the aid and thus also its function in various ways.

[0007] The fluid chambers are made of a suitable flexible, possibly elastic material, preferably a plastic material, which allows the respective chamber volume to be increased or decreased accordingly. A material can also be selected that, when the pressure is increased, assumes a predefined shape without elastically stretching. It can then remain stiffened, for example, by specifically enclosing and stabilizing a body area such as a joint, or by selectively elongating and stretching, transforming into a stiffened shape.

[0008] In principle, only one first fluid chamber can be provided. Only one second fluid chamber can be operated via this one first fluid chamber. If several second fluid chambers are provided, the several second fluid chambers can be operated via the one common first fluid chamber. However, it is also conceivable for two or more first fluid chambers to be provided, which can be actuated together or successively one after the other, depending on the design of the carrier or aid and the local arrangement of the first fluid chambers. Only one second fluid chamber can be operated via the several first fluid chambers, or several second fluid chambers can be operated. These different designs are conceivable for all of the embodiments described below, as far as appropriate.

[0009] According to a further development of the invention, the pressure generating device can be a closed system such that the fluid can be displaced into the second fluid chamber upon compression of the first fluid chamber and from the second fluid chamber into the first fluid chamber upon relief of the first fluid chamber. According to this embodiment of the invention, the fluid is therefore moved back and forth between the two fluid chambers. If pressure is applied to the first fluid chamber, it is emptied to a greater or lesser extent depending on the degree of compression, while the second fluid chamber fills to a corresponding extent and the pressure there is increased. If the first fluid chamber is relieved again, the second fluid chamber, which is under increased pressure, pushes the fluid back into the first fluid chamber, and the local pressure built up via the second fluid chamber is reduced again.In such a closed system, a certain volume of fluid is permanently present, meaning there is no constant fluid exchange into and out of the system during use. Refilling fluid is, of course, conceivable in such a closed system.

[0010] Alternatively, the pressure generating device can also be an open system and comprise at least one valve device via which a fluid can be supplied to the pressure generating device from the outside and / or via which the fluid can be drained to reduce the pressure at least in the at least one second fluid chamber. In this variant of the invention, a quasi-successive fluid exchange therefore takes place. The fluid can either be supplied from the outside, for example into the first fluid chamber after each actuation via the valve device. Alternatively or additionally, it is also conceivable for the fluid to be drained via the valve device to reduce the pressure at least in the second fluid chamber, i.e. when a high pressure is no longer required, this can be reduced accordingly by draining the fluid via a valve device.In this case, an inlet valve allowing fluid supply can be assigned to the first fluid chamber, and a drain valve serving to reduce the fluid chamber pressure or a pressure relief valve defining a maximum pressure in the second fluid chamber can be assigned to the second fluid chamber, wherein a one-way valve is provided between the first and the second fluid chamber. According to this variant, both an inlet valve and a drain valve are therefore provided, via which fluid can be supplied and removed, wherein, as an alternative to the drain valve, a pressure relief valve can also be provided, which allows the pressure in the second fluid chamber to be maintained at a defined level and any excess pressure to be reduced. A one-way valve is expediently provided between the first and the second fluid chamber, which means that in this variant there is no backflow from the second fluid chamber into the first fluid chamber.

[0011] This means that fluid can be pushed into the second fluid chamber via the first fluid chamber until the pressure in the second fluid chamber is sufficiently high. A pressure relief valve only opens when a defined pressure is reached in the second fluid chamber, allowing fluid to be pushed in at will from the first fluid chamber without reaching an excessive pressure.

[0012] The drain or pressure relief valve and the one-way valve are conveniently a combined valve, which means that a valve device or valve unit can be provided which shows the corresponding valve functions.

[0013] As described, the pressure variation is achieved via the carrier and at least the second fluid chamber integrated therein, which has a direct or indirect effect on the body part. The carrier can have a foot section that is to be arranged below a foot when the aid is worn, and a further section that covers another foot, joint, lower leg, or leg section. Alternatively, the carrier can also have a hand section or an arm section. This means that the aid can ultimately be applied to different body parts such as the foot, ankle, lower leg, thigh, hand or wrist, or forearm or upper arm, or has a correspondingly configured carrier so that the pressure variation can occur at the corresponding position via the second fluid chamber.

[0014] In an advantageous further development, when designing a carrier with a section to be arranged in the foot region, it can be provided that the first fluid chamber is provided in a section to be positioned below the sole of the foot, in particular a heel section of the foot section or in a forefoot section of the foot section. If the carrier is designed for arrangement on a wrist or arm, it can be provided that the first fluid chamber is arranged in the hand section. These variants therefore allow the first fluid chamber to be easily accessible or pressed. If the first fluid chamber is on the section on the foot section orthe heel section of the foot section or a forefoot section of the foot section, it is located below the foot in the carrying position and is therefore regularly compressed when the foot puts down or rolls over, so that the fluid is shifted into the second fluid chamber each time. This makes it possible to rhythmically increase the pressure in the second fluid chamber when pressure is applied to the first fluid chamber, or to decrease it when the first fluid chamber is relieved and, for example, the fluid is shifted from the second fluid chamber back into the first. If the aid is arranged on the hand or arm, the first fluid chamber is located on the hand section, so that it is also easily accessible there and can be pressed, for example from the inside of the hand.

[0015] If the at least one first fluid chamber is to be activated while walking, it can preferably be positioned below the sole of the foot, i.e., it is arranged at a section of the wearer's foot. The specific position can be, for example, the heel section, the forefoot section, or, in the case of multiple first fluid chambers, both positions. This generally applies to all embodiments described below, in which an arrangement below the sole of the foot is provided.

[0016] Alternatively, it is also conceivable for a connecting element to be provided on the carrier for detachably connecting the external first fluid chamber. In this variant, therefore, unlike previously described, the first fluid chamber is not integrated into the carrier, but rather is designed as an external element that is to be connected to the carrier to increase the pressure in the second fluid chamber. For this purpose, the carrier has a corresponding connection means, for example, a plug-in valve or similar, to which the first fluid chamber can be connected. Once the first fluid chamber is connected, the fluid can be pumped from it into the second fluid chamber.

[0017] According to a more specific first embodiment of the invention, the aid can be an ankle support, wherein the second fluid chamber, in the worn position, encompasses or overlaps the ankle at least partially on one or both sides, or extends on one or both sides of the Achilles tendon. Consequently, a defined pressure can be built up in the ankle area via the second fluid chamber, for example, to provide lateral support to the ankle joint in this area and prevent twisting. In this variant, the second fluid chamber, for example, permanently stiffens, thus not varying the pressure while walking.

[0018] Alternatively, if, for example, the first fluid chamber is below the heel, a continuous pressure variation can also occur. This is because the pressure in the second fluid chamber automatically increases when the heel strikes the ground, thus stiffening the ankle or joint. As described, the second fluid chamber or a second fluid chamber can run on one or both sides of the Achilles tendon to support and stabilize the Achilles tendon accordingly. This can also be achieved with a constant pressure change, for example, if the first fluid chamber is below the heel. This means that with each step, the second fluid chamber automatically stiffens, thus supporting and protecting the Achilles tendon.A second variant of the invention provides that the aid is a leg stocking which, when worn, extends over the knee, with the second fluid chamber being arranged in the area of ​​the knee, in particular the patella. With this stocking design, a pad function can be achieved via the second fluid chamber, similar to that already described above for the ankle bandage. In such cases, a separate inserted pad is no longer required, or only required to a reduced extent, since the second fluid chamber takes over the pad and thus the support function. Again, an intermittent pressure change can occur here if the first chamber is arranged, for example, below the sole of the foot or below the heel, so that when stiffening or a pad function is required, the pressure is automatically built up, but when the pressure is no longer needed, a corresponding relief also occurs.This is also possible if the first fluid chamber is located, for example, in the back of the knee, since when running there is also a change in shape due to the bending of the knee, which causes a change in the shape of the first fluid chamber.

[0019] Such an arrangement of the at least one first fluid chamber in the back of the knee as described above is in principle also conceivable in the embodiments described below, in which the carrier extends beyond the knee.

[0020] In addition to the design of the aid as a leg stocking, as described above, the aid can also be a knee bandage which extends over the knee in the worn position, wherein the second fluid chamber is arranged in the region of the knee, in particular the patella. In this embodiment, the aid is therefore only a relatively short knee bandage. The first fluid chamber can be provided on the bandage side or on the wearer side, wherein in the worn position the first fluid chamber is actuated several times in order to increase the pressure in the second fluid chamber, which is then also maintained. Alternatively, an external first fluid chamber can also be used, which is connected, for example, via a fluid line and serves to increase the pressure in the second fluid chamber in the worn position, which pressure is then maintained.It is also conceivable to place the first fluid chamber under the heel and to guide the fluid line along the lower leg, for example covered by a stocking, to the knee support, so that an intermittent pressure change can occur there when walking.

[0021] A further variant of the invention provides that the aid is a stocking which, when worn, extends over the ankle, with the second fluid chamber being arranged in the area of ​​the ankle. In this variant, the aid is therefore a short stocking which, for example, only covers the foot and lower leg or calf area. The second fluid chamber is arranged in the area of ​​the ankle so that this area can either be pressurized or stiffened when the second fluid chamber is under increased pressure. Again, the first fluid chamber can be external or integrated into the stocking, whereby it can again be positioned below the heel if necessary. It is also conceivable to keep the pressure once built up in the second fluid chamber remanent or, controlled by an overload valve, to keep it at a defined pressure level.Alternatively, an intermittently changing pressure in the second fluid chamber can of course also be set while walking.

[0022] A further embodiment of the invention provides that the aid has an additional section that can be wrapped around the body part in the worn position. In this aid embodiment, the aid is, at least in part, not designed like a stocking or tube, but has a quasi-flat shape that allows the aid to be wrapped around the body part with this flat section. The aid or section is therefore designed like a "wrap". For example, the aid has a foot section that is tube-shaped and into which the foot can be inserted. Adjoining this is the further, flat section, which can then be placed around the calf, on which further section the second or more second fluid chambers are provided. This variant enables the aid to be put on very easily.For fixation, Velcro fasteners, drawstrings, or similar devices are provided. The first fluid chamber is preferably integrated into the aid and is located, for example, below the heel, so that it is compressed with every step.

[0023] Furthermore, a plurality of second fluid chambers can be provided on the support, in particular the further section or the arm section, distributed around the circumference and / or length. This means that not just one, but several positionally distributed second fluid chambers are provided on the support, the further section or the arm section, all of which communicate at least with the first fluid chamber, but optionally also with each other. This means that a multi-chamber system is formed. Via the plurality of second fluid chambers, pressure variation or stiffening, etc., can of course occur over a significantly larger area than with the integration of only one fluid chamber. However, all of them are operated from a common first fluid chamber, which is again arranged, for example, under a foot section, so that it is automatically activated when walking, provided the aid is one that is attached to the foot or leg.In principle, however, several first fluid chambers can also be provided, via which the second fluid chambers are operated. The same applies to an arm sleeve or similar device, where, for example, corresponding second chambers are provided on both sides of the elbow, which are operated via a common first fluid chamber positioned in the palm area, or via several first fluid chambers.

[0024] It is conceivable here that the plurality of second fluid chambers are quasi-point-shaped, i.e. small-area fluid chambers that are fluidically coupled to one another to form a net or grid-like structure. A net or grid structure is therefore formed across the plurality of point-shaped second fluid chambers. These are, for example, round or polygonal and are connected to one another via narrow connecting channels in the manner of a net, whereby this net is, of course, in turn coupled or coupleable to the first fluid chamber. Via this net structure, a pressure variation can occur over a considerably large area, for example on the calves, or around the thigh, and the like. The point-shaped fluid chambers can be distributed homogeneously over the surface of the further section. This means that a quasi-uniform fluid chamber grid is formed.Pressure variation therefore occurs virtually symmetrically across the occupied area. Alternatively, it is also conceivable for the density of the point-like fluid chambers to vary circumferentially and / or longitudinally. This, in turn, makes it possible to vary the pressure variation in different occupied areas. The greater the fluid chamber density, the greater the pressure increase, and vice versa. This allows a pressure gradient to be created in the circumferential and / or longitudinal directions, whereby, of course, all fluid chambers of this network or grid are supplied via the common first fluid chamber.

[0025] It is advantageous if the density of the point-shaped fluid chambers decreases from the distal end to the proximal end of the support, particularly the wider section or the arm section. Consequently, a higher chamber density is provided in an area farther from the body center, i.e., the distal end, than in an area of ​​the support closer to the body center, i.e., the proximal end, where the corresponding pressure gradient can be generated.

[0026] It is also conceivable for the diameter of the connecting channels connecting the point-shaped fluid chambers to vary. This also allows for pressure variation. Such a variation in the diameter of any connecting channels is, incidentally, conceivable in principle in the embodiments disclosed here, in which several second fluid chambers are connected to one another via such connecting channels, just as any connecting channels connecting a first fluid chamber to a second fluid chamber can vary in diameter.

[0027] As an alternative to designing the aid with a net or grid-like

[0028] Fluid chamber system which defines the second fluid chambers, it is also conceivable for the second fluid chambers to be elongated fluid chambers which, in the worn position, encircle the body part, in particular the lower leg or calf, in sections or in a ring, wherein the fluid chambers follow one another in the longitudinal direction. In this variant, which is conceivable, for example, in the case of a leg stocking or lower leg stocking, a plurality of second fluid chambers which follow one another in the longitudinal direction of the stocking, e.g. ring-shaped or at least elongated, are provided, which are all fluidically coupled to one another, as well as, of course, to a first fluid chamber. As a result, an increased pressure can be generated and exerted locally, e.g. in a ring-shaped circumferential direction, wherein the pressurized area can, of course, vary depending on the corresponding dimensioning of the respective second fluid chamber.This means that, viewed longitudinally, the width of at least some of the fluid chambers can vary. However, this is not mandatory; fluid chambers of equal width are also conceivable.

[0029] If multiple fluid chambers are provided, they are arranged at different positions and connected to the first fluid chamber or to each other via narrow, thin connecting lines. It is also conceivable, however, to use only a second fluid chamber, the edges of which, for example, have a wave-like or meandering design, resulting in larger or wider chamber sections and smaller or narrower chamber sections between them. This means that an area can be occupied by several individual, fluidically connected second fluid chambers, or by a large second fluid chamber whose edge shape divides it into locally different chamber sections or regions.

[0030] The fluid chambers can be coupled to each other, meaning that one fluid chamber is coupled to the next. Alternatively, every second fluid chamber can be coupled to the first fluid chamber via a separate line.

[0031] If the one or more coupled second fluid chambers have different widths (horizontally relative to the wearing position) and / or different heights (vertically relative to the wearing position), the width and / or height of the fluid chambers can preferably decrease from the fluid chamber adjacent to the foot end to the fluid chamber adjacent to the upper end. This means that the fluid chambers become increasingly narrower or shorter as the length of the leg stocking increases, so that a higher pressure or a larger pressurized area is created in the region of the distal end than in the region of the proximal end.

[0032] A further embodiment of the aid according to the invention provides that the aid is a stocking extending at least over the lower leg, wherein a plurality of second fluid chambers are provided which extend in the longitudinal direction of the lower leg. In this embodiment in the form of a stocking, which - like all stocking shapes, be it lower leg, leg, forearm or arm stockings - can be designed as a flat or circular knit, the fluid chambers run in the longitudinal direction, wherein, viewed around the circumference, several such second, longitudinal fluid chambers are naturally provided, which are preferably fluidically coupled to one another. The first fluid chamber, since it is a stocking embodiment, can again be located below the sole of the foot, in particular below the heel section, or can be coupled accordingly as an external fluid chamber.These longitudinal fluid chambers can be used to generate pressure in a quasi-longitudinal direction, whereby a circumferential pressure increase can be achieved with multiple fluid chambers arranged around the circumference. Especially in combination with intermittent compression of the first pressure chamber, this creates a kind of calf muscle pump.

[0033] The second fluid chambers can diverge from the foot end to the top end, meaning that, viewed in the circumferential direction, the distance between the multiple, virtually parallel second fluid chambers widens toward the top of the stocking. If this is not desired, it is conceivable for the fluid chambers to widen from the foot end to the top end. This means that the second fluid chambers are designed in a quasi-trapezoidal shape, with the chamber width increasing from bottom to top, so that ultimately the distance between two adjacent chambers can remain largely constant. In this case, of course, the pressure-exposed area is significantly larger than in the first design variant.

[0034] A further embodiment of an aid according to the invention can provide that the aid is a stocking extending over the lower leg, wherein a flat second fluid chamber encompassing at least part of the lower leg region or a plurality of second fluid chambers distributed around the circumference and length, which are interconnected in a network, are provided. In this variant, in which the first fluid chamber can in turn be provided either below the heel or as an external fluid chamber, at least one large-area second fluid chamber is provided, encompassing at least part of the lower leg region and virtually, preferably completely, encircling the lower leg or calf region. With this variant, it is possible to pressurize the calf region over a large area.This aid design can also be used in conjunction with a corresponding shoe that extends into the calf area, for example, a shoe worn due to an injury, a ski boot, or similar. The one or more second fluid chambers arranged in a quasi-circular manner can close or support the gap between the leg and the shoe upper, thus ensuring a stable fit or support in the shoe, and exerting appropriate pressure on the calf or lower leg area.

[0035] In this context, it is advantageous if the second fluid chamber is lined with or made of a low-friction material. Such a material naturally makes it easier to step into such a shoe, unless it can be placed around the foot or lower leg area as a quasi-open shoe. This is especially true if one or all of the second fluid chambers are located on the outside of the wearer and slide along the shoe material when stepping into the shoe.

[0036] A further embodiment of the aid according to the invention provides that the aid is a stocking extending at least over the lower leg, optionally also over the thigh, on which one or more, preferably larger-area, second fluid chambers are provided, via which pressure can be generated circumferentially on the lower leg, in particular the ankle, and optionally also the thigh. Here, the aid is again designed as a stocking, with the one or more second fluid chambers extending circumferentially around the wearer, so that a corresponding pressure can be built up circumferentially. This means that, for example, the lower leg or the thigh can be pressurized accordingly around its entire circumference.

[0037] At least one pressure relief valve that limits the pressure that can be generated in the second fluid chamber(s) can be assigned to the second fluid chamber(s). This pressure relief valve can be used to achieve a defined chamber pressure, thus preventing overpressure.

[0038] Furthermore, particularly in this variant, but also in other stocking variants, it can be provided that the one or more second fluid chambers are provided on the outside of the wearer, wherein the wearer can be expanded via the one or more second fluid chambers by increasing the fluid chamber pressure. The aid or the wearer is, for example, a compressive item of clothing such as a compression stocking, be it a leg stocking or an arm stocking. This is generally difficult to put on due to its compressive properties. By means of the appropriate arrangement and design of the second fluid chambers, it is now possible according to the invention to geometrically deform these second fluid chambers by filling the second fluid chambers and increasing the chamber pressure, so that the chamber arrangement expands more or less radially and, since the fluid chambers orthe chamber arrangement on the textile carrier also expands the carrier. This means that the compression stocking is expanded, which makes it easier to put on. The fluid chamber system is essentially an integrated donning aid, which of course also makes it easier to take off. As soon as the stocking is put on or taken off, the pressure in the second fluid chambers is reduced again, so that the compression stocking returns to its original shape and, when put on, exerts its compression pressure, or, when taken off, can be folded back up. The first fluid chamber is preferably external and can be detachably connected to the chamber system, so that the user can introduce the fluid and expand the stocking before putting it on, and remove the first fluid chamber again after putting it on.It is also conceivable to arrange the first fluid chamber at a suitable location on the stocking itself, allowing the user to increase the pressure and expand the stocking by repeatedly pressing on the integrated first fluid chamber. In each case, a corresponding release valve is provided, through which the fluid pressure can be released when the support expansion is no longer required, allowing the compression stocking to exert its compression pressure, for example, when worn.

[0039] The multiple fluid chambers can be arranged in a ring-shaped or wave-shaped manner around the circumference, which makes expansion particularly easy, since when these ring-shaped or wave-shaped fluid chambers increase in circumference, they inevitably expand around the entire circumference of the wearer. If the compression stocking has a foot or hand section, elongated second fluid chambers can be provided in the area of ​​the foot or hand section, at least in the ankle area. Alternatively, the second fluid chambers can also be arranged along the wearer and adjacent to one another, so that they press against each other when filled, causing the stocking to expand radially.

[0040] In this embodiment, the pressure generating device can also be detachably mounted on the wearer, meaning that not only the first fluid chamber is detachable, but also the one or more second fluid chambers. These can be designed in the manner of a band or tube or similar and can be detachably connected to the compression stocking, for example, via hook-and-loop fasteners or snap fasteners. This means that once the compression stocking is put on, the pressure generating device can be relieved accordingly and removed, thus eliminating the need to carry it around.

[0041] Yet another embodiment of the aid provides that the aid is an ankle orthosis, wherein in the worn position a second fluid chamber extends from the foot section to the further section and along the same, overlapping the joint on the other side. The basic design of the aid is in the form of a bandage and usually has a stabilizing element, e.g. a splint. The first chamber can, once the aid is applied to the ankle, preferably be located below the heel so that it can be easily activated. According to the invention, the second fluid chamber overlaps the joint or ankle so that the orthosis can be stiffened in the ankle area via the second fluid chamber when it is filled with pressure and stiffens. This can provide protection against twisting, since the orthosis as a whole is stiffened and only exerts an appropriate stabilizing pressure on the joint.This means that the orthosis becomes stiff or rigid as soon as the first fluid chamber is compressed and the pressure in the second fluid chamber is increased. This stabilization can be reversible during walking, meaning that the pressure is increased each time, for example, the heel strikes, and reduced again when the foot is lifted off and the fluid flows back from the second pressure chamber into the first. Multiple second fluid chambers can also be provided, for example, one on each side of the joint, thus providing protection against twisting in both directions.

[0042] In this case, one or both fluid chambers can be assigned a common pressure relief valve, via which the maximum pressure in the fluid chamber can be adjusted. In this variant, there is no intermittent increase or decrease in the fluid pressure in the second fluid chamber. Instead, a defined maximum pressure is built up in the second fluid chamber through one or more occurrences. This pressure is maintained even when the first fluid chamber is compressed again, since the pressure relief valve ensures constant pressure.

[0043] According to yet another embodiment of the aid, the aid can also be a foot drop orthosis, wherein at least one second fluid chamber is provided which, in the worn position, extends at least partially in an L-shape from the foot section to the further section and can be stiffened by generating a fluid chamber pressure. In this embodiment, the L-shaped second fluid chamber is located at least partially in an area which, in the worn position, lies on the instep of the foot; alternatively, an L-shaped second fluid chamber can be arranged on one side of the foot, or a second fluid chamber on each side of the foot. The first chamber is again preferably positioned below the heel in the worn position.When the heel is struck, the pressure in the second fluid chamber increases, causing it to stiffen. Due to the L-shaped chamber design, the foot is essentially pulled or held upwards by the toes, preventing it from bending downwards or, depending on the specific condition, falling downwards. The foot is thus lifted accordingly by filling one or more second fluid chambers, or released when the second fluid chamber is relieved.

[0044] Two second fluid chambers can also be provided, running on either side of the foot and lower leg; alternatively, a second fluid chamber can be provided above the instep and in front of the shinbone. Both designs serve the same purpose, as their L-shape provides appropriate stiffening and prevents the foot from falling downward around the joint or remaining raised.

[0045] At least one release valve can be assigned to the second fluid chamber(s), via which the pressure in the second fluid chamber(s) can be reduced with a time delay or electrically controlled when the first fluid chamber is relieved. In order to enable as "normal" a gait as possible, this variant essentially creates a time delay with regard to the relief of the second fluid chamber(s). This means that the relief or emptying only occurs when the foot has already lifted off the ground and swings forward, as is known from normal gait. With the relief, the foot can swing downwards again slightly until the heel hits the ground again and the first pressure chamber is compressed again, which in turn stiffens the second fluid chamber(s) and thus lifts the foot.The time delay can be achieved either via the release valve, which is designed to release the pressure only after a certain time or slowly. Alternatively, an electronically controlled release valve can be provided.

[0046] According to yet another embodiment of the aid, the aid can be a stocking or bandage which, in the worn position, extends with the further section at least over the lower leg, wherein at least one elongated second fluid chamber is provided which extends from the foot section or the heel section of the wearer along the further section and shortens in the longitudinal direction when the pressure in the second fluid chamber increases. This aid variant can, for example, serve as Achilles tendon support. The at least second fluid chamber, which extends from the heel section of the wearer along the further section and runs along the Achilles tendon, shortens when the pressure increases, i.e. it contracts in the longitudinal direction of the Achilles tendon. This leads to the foot being stretched, i.e. the tip of the foot is essentially actively rotated downwards around the ankle.This design supports the movement into the toe-stand position when running. The first fluid chamber is located below the heel, so that when the foot strikes, the pressure in the second fluid chamber increases, shortening it and supporting the further rolling or toe-lifting movement.

[0047] Yet another embodiment of the aid provides that it is a leg stocking or a bandage, wherein at least one second fluid chamber, preferably a plurality of second fluid chambers, are positioned on the wearer such that in the worn position they extend along the further section over the knee joint. In this variant, the second fluid chamber or chambers run to the side of the knee joint. In the case of a leg stocking, the first fluid chamber is preferably located below the heel, and is therefore automatically compressed when the foot is loaded, so that the pressure in the second fluid chamber or chambers is increased. The arrangement to the side of the knee joint, preferably on both sides, leads to a corresponding stiffening of the aid in this area.Since the pressure in the first fluid chamber increases when the heel is loaded, which is the case when standing up, for example, this device can be used as a standing aid. The stiffening second fluid chambers, which are elongated in the compressed, stiffened state and are pressure-free and angled according to the leg shape when sitting, exert a force on the thigh relative to the lower leg, thus supporting the standing-up process. This type of leg stocking—the same applies to a knee brace—can therefore support the standing-up process.

[0048] Yet another embodiment of an aid according to the invention provides that the aid is an insole, wherein the first fluid chamber is arranged on the foot section or the heel section of the foot section and at least one second fluid chamber is arranged on a forefoot or midfoot section of the foot section positioned below and / or to the side of the midfoot or forefoot in the worn position. This embodiment of the aid can serve to guide and influence the rolling movement. The insole is used in a shoe. When the heel is stepped on, the first fluid chamber is compressed and the pressure in the second chamber located in the midfoot or forefoot area increases. This supports the rolling or push-off movement of the foot from the ground.

[0049] In an alternative variant, the aid can again be an insole, wherein the first fluid chamber is arranged in a forefoot section of the foot section positioned below the forefoot in the worn position, and at least one second fluid chamber is arranged in a midfoot section of the foot section positioned below and / or to the side of the midfoot in the worn position. In this variant, viewed from the heel to the toe, the second fluid chamber is essentially arranged upstream of the first fluid chamber. When the forefoot is loaded, the first fluid chamber is compressed and the pressure in the second fluid chamber, which is located in the midfoot region, is increased. This creates a type of repulsion of the foot in the midfoot region, which supports the midfoot arch during the rolling movement.

[0050] In yet another variant, the aid can be a glove or an arm bandage, wherein the first fluid chamber is positioned on the wearer such that, in the worn position, it is located on the palm of the hand. In this embodiment of the aid in the form of an arm sleeve or an elbow sleeve or a corresponding bandage, a corresponding pressure is exerted on a corresponding wrist, forearm, or elbow section via the one or more second fluid chambers.

[0051] The second fluid chamber, which can be designed in the form of a pad, for example, located in the area of ​​the elbow joint, is connected to the first fluid chamber, which is located on the inside of the wearer's hand. Each time this first fluid chamber is activated, for example, by actively pressing it, the second fluid chamber is filled with fluid and the pressure is increased, allowing it to perform its pad function.

[0052] Furthermore, at least one connection for an external pump or a fixed pump, via which the pressure in at least one of the fluid chambers can be changed, can be provided. This embodiment applies to each of the aid embodiments described above. This means that the pressure in one of the fluid chambers, i.e. in the pressure generating device, can be specifically changed or adjusted via an external pump, which can be a manual pump or an electric pump, preferably one controllable via a control device. This can, for example, be used to set a certain minimum pressure in the pressure generating device, which is given by default and which can be varied accordingly by compressing the first chamber.

[0053] For each design of an aid, a corresponding valve device can be provided, if necessary, via which a fluid can either be supplied from the outside or a fluid can be drained, or excess pressure can be regulated, etc. The use of a corresponding valve device depends, as described, on the design of the aid and the desired functionality. For example, air can be used as the fluid if it is a closed and an open system. In the case of a closed system, the use of a liquid such as water or oil is also conceivable. Fluids with different flow properties, e.g. different viscosities, can also be used, in particular a dilatant fluid. This can create specific flow conditions in different situations. E.g.the fluid flows into the second chamber faster than it flows back into the first chamber.

[0054] The pressure-generating device, or the first and second fluid chambers, as well as corresponding fluid or connecting lines, are made of a correspondingly flexible material, which can preferably be molded into a defined shape, particularly in designs of the aid where a corresponding final shape is important, for example, to support or inhibit a movement, etc. In this case, the respective second fluid chamber must not expand, but must be dimensionally stable under high pressure. Suitable plastic materials, such as Teflon foils or similar, are suitable for this purpose.

[0055] The arrangement or integration of the pressure generating device on or in the carrier can be achieved, for example, by gluing, welding, or sewing, whereby the arrangement can be made either on the outside of the carrier, on the inside of the carrier, or between two carrier layers, relative to the carrying position. Further advantages and details of the present invention will become apparent from the exemplary embodiments described below. In the following, the figures show:

[0079] Fig. 1 shows a therapeutic aid 1 according to the invention in the form of an ankle stocking 2, which is shown here already in the worn position on a body part 3. The aid 1 has a textile carrier 4, for example a knitted fabric, in particular a compression knit consisting of a base knit and one or more inserted, elastic compression or weft threads (this embodiment applies fundamentally to all carriers described below, as long as they are stockings, bandages or orthoses). In the example shown, this carrier 4 has a foot section 5 to be arranged below the foot with a heel section 6 that receives the heel of the foot, as well as a further section adjoining the foot section, here a joint section 7. The carrier 4 is designed here as a tubular knit, which is produced, for example, as a flat or circular knit.

[0080] A pressure generating device 8 is provided on the support 4, comprising a first fluid chamber 9, which is arranged on the heel section 6, i.e., in the worn position, is located below the heel of the foot. The first fluid chamber 9 communicates with two second fluid chambers 10 (see also Fig. 2), which show the aid 1 from the other side. The two second fluid chambers 10 are arranged to the side of the ankle of the foot. They have an L-shape and essentially run slightly around the ankle. In the example shown, the pressure generating device 8 is also a closed system, with a fluid, for example, air or a liquid, being accommodated in both fluid chambers 9, 10. The fluid chambers 9, 10, as well as the connecting lines connecting them, are made of a suitable, flexible plastic material that is preferably not elastic, but can be filled with a correspondingly high fluid pressure.The pressure generating device 8 or the fluid chambers 9, 10 can be arranged on the outside of the carrier 4, as shown in Figures 1 and 2. They can also be arranged on the inside, or, if the carrier 4 is double-layered in this area, between two corresponding carrier layers. They are fixed to the carrier, for example, via an adhesive or welded connection, but they can also be sewn or otherwise firmly connected to the carrier 4.

[0081] As described, the first fluid chamber 9 is arranged below the sole of the foot or at the heel section 6. In the carrying position, it is therefore located below the heel. This means that when walking and the foot touches the ground with the heel, the first fluid chamber 9 is inevitably compressed. The fluid contained therein, for example the air or gas, is forced out of the first fluid chamber 9 and conveyed into the two second fluid chambers 10. There, the pressure increases, and the two L-shaped fluid chambers stiffen, assuming a relatively stable L-shape that depends on the respective pressure level. This stiffening not only exerts a correspondingly increased pressure on the underlying area of ​​the foot, i.e. the ankle area, but also provides lateral support for the ankle area, thus counteracting twisting.

[0082] As soon as the heel is lifted off the ground, the first pressure chamber 9 is relieved. This leads to the high pressure in the second fluid chambers 10 being reduced again and the fluid absorbed there under high pressure being pushed back into the first fluid chamber. The two second fluid chambers are relieved and the stiffening is reduced or eliminated. The joint stabilization is temporarily canceled because it is no longer needed once the foot has lifted off. However, as soon as the foot is put back down, the first fluid chamber 9 is compressed again, the second fluid chambers 10 are stiffened again and a new stabilization process begins. This means that with this design, an intermittent increase and reduction in pressure occurs within the second fluid chambers, thus resulting in temporary, intermittent stiffening in the ankle area.

[0083] Fig. 3 shows a further embodiment of a therapeutic aid 1 according to the invention, wherein - this applies to all embodiments and figures described below - the same reference numerals are used for the same elements. The aid 1 corresponds in its function to the aid 1 from Figs. 1 and 2, i.e. it is also designed as an ankle stocking 2, with a textile carrier 4 with a foot section 5 together with a heel section 6 and a joint section 7. Again provided is a first fluid chamber 9, not shown in detail, provided on the foot section 5, preferably on the heel section, as well as two second fluid chambers 10 provided on the sides in the ankle area, only one of which is shown in Fig. 3. In this embodiment, an external pump 11 is provided, which is detachably connected to a connection means 12, which is assigned to a second fluid chamber 10. For example, a plug connection can be formed.Using the pump 11, a hand pump or electric pump, a basic or base pressure can basically be set within the pressure generating device 8 or, should such a basic or base pressure decrease slightly over the course of the wearing time, the pressure can be adjusted again. The connecting device 12 can also be designed as a valve device 13 and comprise an overpressure or drain valve or such a valve combination in order to prevent excessive pressure or, if necessary, to reduce the overall chamber pressure or to drain the fluid. The basic function of this aid 1 has already been described with reference to Figures 1 and 2. Figure 4 shows an embodiment of an aid 1 which is designed here as a kind of leg stocking, although in the example shown it is not continuous.The aid 1 in turn consists of a textile carrier 4, again for example a knitted fabric such as a compression knit. This carrier 4 has a foot section 5, which accommodates the heel area and the ankle area of ​​the foot. This foot section 5 is followed by a further section, here the lower leg section 14, which is not tubular, but extends upwards only on the outside or, not shown, also on the inside of the lower leg. This further lower leg section 14 is followed by a further section in the form of an upper thigh or leg section 14, which is again tubular and encompasses the knee joint. A corresponding pressure generating device 8 is again provided, with a first fluid chamber 9 arranged on the foot section 5 or its heel section 6, which is not shown in detail.Extending along the foot section 4, the lower leg section 14, and the thigh or leg section 15 are two second fluid chambers 10, which are coupled to one another, i.e., at the upper end, as shown in Fig. 4, they merge into one another or are connected. Furthermore, a further second fluid chamber 10' is provided, which surrounds the kneecap, thus essentially functioning as a patella pad. Both the fluid chambers 10 and the fluid chamber 10' are fluidically connected to the first fluid chamber 9. Since this is located below the heel of the foot, it is compressed with each step, and the fluid is pressed into the second fluid chambers 10, 10', which then stiffen, so that on the one hand, the fluid chambers 10 laterally stiffen and stabilize the knee joint, just as the fluid chamber 10' supports the knee joint in the area of ​​the patella and fixes the kneecap.This stiffening or stabilization is provided at the time it is needed, namely when the leg is loaded. As soon as the heel is lifted again, the fluid pumped into the second fluid chambers 10, 10' is pushed back into the first fluid chamber 9, or a corresponding pressure reduction begins, and the stabilization and stiffening is canceled. Only when the heel touches down again does another stiffening and stabilization cycle begin. In the example shown, the fluid chambers 10 and the fluid chamber 10' can be fluidically coupled to one another, so that the fluid is pumped from the first fluid chamber 9 via the second fluid chambers 10 into the further second fluid chamber 10'. Alternatively, it is also conceivable for the second fluid chamber 10' to be fluidically coupled directly to the first fluid chamber 9.

[0084] Again, a closed system is shown here. It is conceivable, similar to what was already described for Fig. 3, that a corresponding connection means 12 is provided at a suitable location, to which an external pump 11 can be connected, and which can also be designed as a valve device 13 at the same time.

[0085] Fig. 5 shows a therapeutic aid 1, which is again to be positioned in the foot and lower leg area and serves, for example, for stabilization and massage in the area of ​​the Achilles tendon or the lower leg in general. This aid 1 again has a textile carrier 4, which, however, is not designed as a tubular textile part, but rather as a quasi-open, flat textile part that can be folded or wrapped around a body part and fixed to it. For this purpose, the carrier 4 has a relatively large section that is to be wrapped around the lower leg; this is thus a lower leg section 14.A plurality of strap-side tabs 16 are provided on said support, on which corresponding fastening means 17, such as hook-and-loop fasteners, are provided. These can interact or hook with the textile material of the support 4 in the wrapped position, so that a corresponding wrapped tube shape can be securely placed on the leg. The support 4 also has a corresponding foot section 5, which is also flat and has a fastening means 17, again in the form of a hook-and-loop fastener, and which is placed around the foot. The further section, i.e. the lower leg section 14 and the foot section 5, are connected via a connecting section 18 of the support 4, so that a one-piece aid is again produced. A corresponding pressure generating device 8 is also provided with a first fluid chamber 9, which is arranged on the foot section 5 and is again positioned below the sole of the foot, in particular in the area of ​​the heel.This is connected via a connecting line 19 to a plurality of second fluid chambers 10, which are here point-shaped and which are also connected to one another via corresponding connecting lines 19. This results in a type of net or lattice structure on the part of the second fluid chambers 10. In the wearing position, these second fluid chambers 10 are positioned in pairs on either side of the Achilles tendon; there they generate a corresponding supporting or stabilizing pressure that stabilizes the Achilles tendon. The function is again as already described above. If the foot is stepped on the ground, the first fluid chamber 9 is compressed immediately upon contact, the fluid is displaced within the closed system into the second pressure chambers 10, where the corresponding pressure build-up begins and the chamber stiffening or bulging takes place. During loading of the foot or the Achilles tendon area, the stiffening or bulging remains.Arching is maintained, but as soon as the heel lifts off the ground and the pressure on the first fluid chamber 9 is reduced, the fluid is pushed back into the first fluid chamber 9 due to the high internal pressure in the second fluid chambers 10, the stiffening or the pressure build-up in the second fluid chambers 10 is reduced again and the support function is temporarily canceled until the heel touches the ground again.

[0086] Fig. 6 shows an aid 1 according to the invention, which corresponds in structure to that of Fig. 5. The carrier 4 again has a foot section 5 and, as a further section, a lower leg section 14. Both sections 5, 14 are again open and flat and can be wound around the leg or foot in a tubular shape, for which purpose the corresponding closure means 17 are provided on the foot section 5 or the tabs 16 in the form of hook-and-loop fasteners (press fasteners or the like are also conceivable). Again, a corresponding pressure generating device 8 is provided, with the first pressure chamber 9 provided on the foot section 5 and a plurality of further second fluid chambers 10, which are again point-shaped and are arranged in a grid or net-like manner on the lower leg section 14. The second fluid chambers are arranged distributed essentially homogeneously over the surface of the lower leg section 14.Via a connecting line 19, the first fluid chamber 9 is connected to a second fluid chamber 10. The second fluid chambers 10 are fluidically connected to one another via further connecting lines 19, so that upon impact and compression of the first fluid chamber 9, the fluid is automatically displaced into all second fluid chambers, resulting in a localized, yet virtually large-area pressure buildup. This can achieve a massage effect as well as a drainage effect, even in the area of ​​the entire lower leg. The four second fluid chambers 10, which are quasi on the inlet side, are arranged in the Achilles tendon area, similar to the design according to Fig. 5, while the other second fluid chambers 10 are then positioned along the calf area.Due to the firm, tubular wrapping, a corresponding pressure can be built up, which is intermittent, as it is naturally released when the heel is relieved, thus relieving the first fluid chamber 9. This results in intermittent compression and thus a kind of lymphatic or drainage effect, or a kind of calf pump. Furthermore, a corresponding support or stabilizing pressure is built up in the area of ​​the Achilles tendon.

[0087] Fig. 7 shows the aid 1 from Fig. 6 in the worn position. It can be seen that the foot section 5 is placed in a quasi-ring shape around the foot in the area of ​​the heel. The first fluid chamber 9, which, like the second fluid chambers 10, is arranged on the inside of the carrier 4 in this exemplary embodiment, as shown by the somewhat thinner lines, is located in the area of ​​the heel. The further second fluid chambers 10 are positioned in the area of ​​the Achilles tendon or the back of the lower leg, i.e. in the calf area. It can be seen that the lower leg section 14 containing them is also wrapped around the lower leg in a tubular shape and strapped tightly. Although Figures 5 to 7 show an essentially homogeneous distribution of the second fluid chambers 10, a variation in the chamber density in the circumferential and / or longitudinal direction is also possible.This allows a pressure gradient to be established in the circumferential and / or longitudinal direction, with the pressure increasing the higher the chamber density. For example, the chamber density can decrease from the distal end to the proximal end of the carrier 4.

[0088] Although only a type of calf stocking is shown in Figures 5 and 6, the support can of course also extend into the thigh region, whereby, starting from Figure 6, corresponding additional second fluid chambers can also be provided in the thigh region. A design as a pure thigh or knee stocking is also conceivable, in which case the foot section 5 arranged in the heel region is connected to the further section on the thigh or knee via a correspondingly long connecting line. Alternatively, the first chamber can also be arranged in the back of the knee.

[0089] The plurality of second fluid chambers 10 of the embodiments according to Figures 5 to 7 can be formed on a common support component that is fixedly or detachably attached, e.g., glued, to the support 4. This flat support component allows for simple arrangement of the plurality of fluid chambers or the chamber system comprising the second fluid chambers. The connecting line 19 and the first fluid chamber 9 can, of course, also be formed integrally on the support component, so that they too can be arranged in a single, common fastening process on the support 4. The support component is preferably made of a suitable plastic that allows the chamber formation, e.g., a Teflon film or the like.

[0090] Fig. 8 shows an aid 1, again in the form of a lower leg stocking, although this aid can also be designed as a complete leg stocking. A support 4 with a foot section 5 and a lower leg section 14 is provided, as well as a pressure generating device 8 comprising a first fluid chamber 9, which is arranged at one end of the foot section or at the heel section 6 of the foot section. Extending from this, preferably on both sides of the ankle, are second fluid chambers 10, which can stabilize the ankle on both sides. From these two fluid chambers 10, several further fluid chambers 10' extend along the tubular stocking shaft, i.e., upwards along the lower leg, with the fluid chambers 10' being fluidically coupled to one another in pairs and fluidically connected to one another via a common pressure distribution chamber 20 in the lower region near the heel.The fluid chambers 10' run, at least in pairs, essentially parallel to each other. Their spacing, relative to the respective chamber pair, preferably widens slightly from bottom to top, toward the upper edge of the stocking. However, it would also be conceivable to increase the width of the individual fluid chambers 10' upwards, so that the chamber size consequently widens toward the top, etc., meaning that a different chamber design can be used.

[0091] The function is such that when the heel touches the ground, the first fluid chamber 9 is compressed. The fluid is forced out and pressed into the two lateral ankle-side fluid chambers 10, as well as into the further, longitudinal fluid chambers 10'. Consequently, the fluid chambers 10, 10' stiffen and, on the one hand, stabilize the joint or ankle area, while, on the other hand, the calf muscles are compressed via the further, second fluid chambers 10', so that a type of intermittent massage effect is created, or rather, a calf muscle pump can be realized, resulting from the alternating increase and decrease in compression pressure. This intermittent pressure change naturally also results from the changing load on the first fluid chamber when the heel is placed on the ground or lifted off. In addition, the support 4, i.e., the knitted egg I, is influenced by the stretching of the knitted fabric.By stretching the knitted fabric, the compressive properties of the carrier 4 change. Although only a lower leg stocking is shown here, the aid 1 can also be designed as a complete leg stocking, i.e., the additional second fluid chambers 10' also extend into the thigh area.

[0092] Fig. 9 shows an embodiment of the aid 1 from Fig. 8, the design and function of which are identical to that described for Fig. 8. In addition, however, an external pump 11 is provided here, which in turn can be detachably connected to a second fluid chamber, here a fluid chamber 10', via a connection means 12, which can also be or comprise a valve device 13. This makes it possible to adjust the basic or base pressure within the pressure generating device 8 as required, i.e. to increase or reduce it in a targeted manner, as required. If the corresponding valve device 13 is provided, this can in turn be designed as an overload valve or drain valve or as a combined valve device providing these functions.

[0093] Fig. 10 shows a schematic diagram of an aid 1, which is again designed as a lower leg stocking and has a textile carrier 4 with a foot section 5 and a lower leg section 14. Again, a corresponding pressure generating device 8 is provided, with a first fluid chamber 9, which is in turn arranged on a foot section 5 or its heel section 6 of the wearer 4 and is located below the wearer's heel in the wearing position. The first fluid chamber 9 is fluidically connected to a plurality of second fluid chambers 10, which are positioned around the circumference of the lower leg section 14, which is in turn designed as a tube, wherein the fluid chambers 9, 10 are fluidically connected to one another via a connecting line 19, just as the pressure chambers 10 are fluidically connected to one another via connecting lines 19.The second fluid chambers can again be distributed essentially homogeneously; alternatively, a density variation in the circumferential, in particular in the longitudinal direction, can be provided to generate a pressure gradient. The fluid chambers can also be formed here on a separate support component that is, for example, glued to the support 4. With this design, when the foot hits the ground and the fluid is shifted from the first fluid chamber 9 into the second fluid chambers 10, the pressure is increased locally across the entire circumference, creating a multitude of local pressure points which, however, as a whole, in turn generate increased pressure on the calf muscles. This, in turn, can generate a type of massage, drainage, or pumping effect that acts on the calf muscles.

[0094] Furthermore, this design can also be used to ensure a stable fit in a boot, such as a ski boot or a higher hiking boot. This is because the circularly encircling second fluid chambers 10, whose volume increases upon filling or pressure increase, can fill the circular gap or space between the leg and the shoe or boot shaft. This results in a more secure fit of the foot or calf area in the shoe or boot shaft. Alternatively, the second chambers 10 shown can also be formed by only one or a few second large-area chambers.Since, for example, in a ski boot used for skiing, there is no significant pressure variation in the area of ​​the first fluid chamber 9, a permanently elevated pressure can be maintained in the second fluid chambers 10 when the foot is firmly in the ski boot, thus providing a permanent, stable improvement in support. If the fluid chambers are arranged on the outside of the carrier 4, they should be made of a low-friction material such as Teflon.

[0095] Even with this embodiment, it is of course conceivable to provide an additional, detachably connectable external pump 11, which can be connected via a suitable connection means, for example, to one of the upper second fluid chambers 10, via which an additional pressure increase can be set in the second fluid chambers, if necessary. Figures 11 and 12 show a schematic diagram of an aid 1 in Fig.

[0096] 11, which features an integrated donning and doffing aid for a compression stocking. Figure 12 shows its function in three partial views.

[0097] The aid 1 again comprises a textile carrier 4 with a foot section 5 and, in this case, a lower leg section 14. In this example, several second fluid chambers 10 are provided along the outside of the lower leg section 14, which in turn are fluidically coupled via a connecting chamber 20.

[0098] In this embodiment, the first fluid chamber 9 is arranged externally to the wearer 4 and is designed in the form of a connectable pump that can be detachably connected to a connecting means 12 provided on the wearer side, which in turn can also be a valve device 13. In this embodiment, the arrangement and function of the second fluid chambers 10 is such that they enable the textile lower leg section 14, which is designed, for example, as a compression knit that is somewhat complicated to apply, to be radially expanded for easier donning and doffing. For this purpose, when the first fluid chamber 9 is connected, a fluid, for example air, is pumped into the second fluid chambers 10 via the first fluid chamber 9, i.e. the pump 11.These stiffen, and in this example, can also expand, supporting each other circumferentially. Due to their change in geometry and their firm connection to the textile lower leg section 14, they essentially carry the textile material of the lower leg section 14 with them and also expand radially. The pressure increase continues until a corresponding degree of expansion is reached, allowing easier donning and doffing.

[0099] Fig. 12 with its sub-figures a), b) and c) shows the basic function. Sub-figure a) shows the aid 1 from Fig. 1 in the unworn position, the second fluid chambers 10 are emptied or depressurized. The interior space enclosed by the textile carrier 4 is, viewed radially, relatively small. After connecting the first fluid chamber 9 or the pump 11 and inflating the second fluid chambers 10, these increase their volume and expand, as sub-figure b) in Fig. 12 clearly shows. Ideally, the second fluid chambers 10 support each other laterally or circumferentially. Due to the increase in pressure and the increase in volume, the carrier 4 is inevitably carried along and expanded. The result is an expanded, cylindrical carrier cross-section, shown ideally in Fig. 12. This expanded compression stocking now makes it easier to put on and, of course, to take off.

[0100] After putting on the compression stocking, the first fluid chamber 9 is released again and the high pressure in the second fluid chambers 10 is reduced or released again via the valve device 13, so that the carrier 4 contracts again and rests against the body part with its compression pressure, as shown in sub-figure c) in Fig. 12.

[0101] It is conceivable that this pressure generating device 8 or the second fluid chambers 10 are also detachably connected to the knitted fabric, thus allowing them to be used as an external donning aid. For this purpose, it is conceivable to arrange the second fluid chambers 10, for example, on a common carrier that can be wrapped around the stocking and connected to the actual textile carrier 4. Via this correspondingly firm connection, the textile carrier is accordingly carried along and expanded when the second fluid chambers 10 are inflated. If this donning aid is no longer required, it can be detached from the carrier 4 again after the pressure in the second fluid chambers 10 has been relieved.

[0102] Instead of the second fluid chambers running along the lower leg section, these can also be arranged in a ring-shaped or wave-shaped manner around the circumference and in the longitudinal direction, and of course can be fluidically connected to one another. A design as a complete leg stocking is of course also conceivable. Fig. 13 shows an aid 1 in the form of a bandage or orthosis to be applied on the ankle side. It again comprises a textile carrier 4 with a foot section 5 and a relatively narrow lower leg section 14, both of which are connected to one another via a corresponding connecting section 21. The aid 1 is here again designed as a flat aid, similar to that already described for the aid in Figs. 5, 6 and 7, which can be wrapped around the foot or ankle area and tightened with corresponding connecting means 17, for example corresponding Velcro fasteners or the like.Appropriate fastening straps or tabs are therefore provided.

[0103] Again, a corresponding pressure generating device 8 is provided, which has at least a first fluid chamber 9, which in turn is arranged below the heel. Along the connecting section 21, a plurality of further, point-like fluid chambers 10 are provided, which are interconnected in a quasi-network or grid-like manner. Such a connecting section 21 is provided on both sides, i.e., such a connecting section and thus the corresponding second fluid chambers 10 extend on both sides of the ankle, overlapping the ankle. If the first fluid chamber 9 is now loaded when the heel is struck, the fluid is displaced and fills the second fluid chambers 10, which are thus stiffened. This means that the entire net or grid structure, as shown in Fig. 13, stiffens, thereby stiffening both sides of the ankle to protect against twisting.

[0104] Instead of forming smaller, point-like second fluid chambers 10, as shown in Fig. 13, it is of course also conceivable to provide only one continuous second fluid chamber 10 per side, which is, for example, elongated, but which can also be designed, similar to the mesh or lattice structure shown in Fig. 13, as a quasi-perforated mesh structure or lattice structure, without dedicated individual larger, point-like chamber sections being provided. It is also conceivable for the second fluid chamber 10, as described in Fig. 4, to be formed in this exemplary embodiment by two continuous, elongated fluid chambers 10. Fig. 14 shows the aid 1 from Fig. 1 from the other side, where the second connecting section and the second fluid chambers 10 provided there are shown, which are fluidically connected to the first fluid chamber 9.

[0105] Fig. 14 clearly shows that in the example shown, two first fluid chambers 9 are provided which, in the longitudinal direction of the foot, are arranged downstream of one another, but both communicate with the second fluid chambers 10 arranged downstream of them. The two first fluid chambers 9 are loaded at different times during walking, so that corresponding stabilization is possible in different gait or loading phases, since a pressure variation occurs within the second fluid chambers 10 at different times. This can be expedient depending on the given therapy requirement. In this context, it is conceivable that, for example, a first fluid chamber 9 is arranged in the heel area and a further first fluid chamber 9 is arranged in an area near the forefoot or ball of the foot, or something similar. In this example, it is also conceivable that the first fluid chamber 9 is formed by only a single chamber.

[0106] Fig. 15 shows an embodiment of an aid 1, again comprising a textile carrier 4 with a foot section 5 and a lower leg section 14, on which textile carrier a pressure generating device 8 is arranged. This also comprises a first fluid chamber 9 (not shown in detail), located below the foot or heel, which communicates with a plurality of second fluid chambers 10, all of which are fluidically connected to one another. These second fluid chambers 10 extend, on the one hand, quasi to the side of the ankle and upwards along the lower leg section 14, as Fig. 15 shows. A central second fluid chamber 10 extends along the shinbone and over the instep of the foot to a lower fluid chamber section that runs transversely over the instep or around the foot.

[0107] With such an aid, a foot lift orthosis is realized.

[0108] When the foot hits the ground, the first fluid chamber located on the underside of the foot is compressed as described, and the fluid is pushed into the second fluid chambers 10, which stiffen. Due to the L-shaped arrangement of at least the middle second fluid chamber 10, which extends along the shinbone and over the instep as described and then merges into the fluid chamber section running transversely over the instep and around the foot, this L-shaped chamber structure is stiffened, which in turn means that the foot remains lifted and therefore does not fall uncontrollably downwards when the heel is relieved of pressure. The foot therefore remains slightly lifted, and only after a corresponding delay does the pressure relief in the second fluid chamber(s) 10 begin and the stiffening is at least partially removed, allowing the foot to pivot downwards around the joint again, as is the case with normal walking.This active foot elevation prevents the foot from dragging on the ground in an uncontrolled manner when walking, which can lead to accidents.

[0109] The time delay can be realized, for example, via a drain valve 22, shown here only in principle, which is assigned to a second fluid chamber 10, wherein the first fluid chamber, not shown in detail, is assigned an inlet valve, likewise not shown in detail, via which in turn fluid, in this case ambient air, can be sucked in, so that in turn a corresponding fluid volume is present in the pressure generating device.

[0110] Instead of a central, L-shaped second fluid chamber, it would also be conceivable to provide two lateral, L-shaped second fluid chambers, one running along the side of the lower leg and the other along the side of the foot. The lifting function can also be realized using fluid chambers shaped or arranged in this way.

[0111] Figures 16 and 17 show an aid 1 which is again designed as a flat, open aid that can be wrapped around the foot or lower leg. It again comprises a carrier 4 with corresponding tabs or straps, which are equipped with suitable connecting means 17, via which a corresponding fixed connection can be achieved in the worn position. A pressure generating device 8 is again provided, with a first fluid chamber 9 arranged below the heel on a foot section 5 of the carrier 4. At the further section, i.e. the lower leg section 14, a second fluid chamber 10 is provided, which is elongated and extends upwards from the heel section 6 of the wearer along the lower leg section 14. The second fluid chamber 10 is structured here and has several wider chamber sections that are connected to one another via narrower connecting sections.The second fluid chamber 10 is connected to the first fluid chamber 9 via a connecting line 19. The second fluid chamber 10 is positioned along the Achilles tendon and the back of the lower leg in the support position, as clearly shown in Fig. 16. The first fluid chamber 9 is in turn connected to the second fluid chamber 10 via a connecting line 19. Alternatively, the fluid chamber can also be arranged laterally on the support 4.

[0112] The design and arrangement of the second fluid chamber 10 is such that the entire chamber arrangement of the second fluid chambers 10 contracts longitudinally when the pressure is increased. This means that the entire chamber length is shortened, which results in the heel being pulled slightly upwards, as the wearer 4 sits firmly on the lower leg, and the foot being actively pivoted around the ankle joint. This can support foot extension, meaning that walking support and support for the movement into the toe stand can be achieved.

[0113] At the same time, since in the example shown the individual chamber sections of the second fluid chamber 10 also extend somewhat in the circumferential direction around the calf area, a corresponding stabilization can be achieved in the calf area and in particular in the Achilles tendon area.

[0114] Fig. 18 shows an aid 1 that can be used as a standing aid. It is

[0115] Designed as a leg stocking or bandage, with a foot section 5 and an adjoining further section in the form of a lower leg section 14, which is relatively narrow here and extends upwards on both sides of the lower leg and merges into a thigh or leg section 15, which in turn is tubular and encompasses the knee joint. A corresponding pressure generating device 8 is provided with a first fluid chamber 9 (not shown in detail) provided on the foot section 5 or its heel section 6, which is connected via connecting lines 19, which are arranged on at least one lower leg section 14 and extend to the thigh or leg section 15, to a second fluid chamber 10 arranged on this thigh or leg section 15 and located to the side of the knee joint.Preferably, such a second fluid chamber 10 is provided on both sides of the knee joint, with corresponding connecting lines 19 then running lengthwise on both lower leg sections 14.

[0116] The function is such that when a person is sitting and wishes to stand up, increased heel pressure inevitably occurs, resulting in the first fluid chamber 9 being compressed and the fluid being displaced into one or two lateral second fluid chambers, which incidentally can also be formed by one or more second fluid chambers on the back of the leg. These stiffen and, due to this stiffening, are forced into their elongated shape shown in Fig. 18. Due to their firm connection to the leg section 15, this stiffening inevitably applies a supporting pressure or a supporting moment to the leg, which supports the standing-up movement and thus the rotational movement around the knee joint.This means that at the exact moment when a corresponding force is required to stand up, force support is provided by the second fluid chambers 10 stiffening and assuming their elongated shape.

[0117] This also provides appropriate running support, since when the first fluid chamber 9 is relieved, the pressure in the second fluid chambers 10 is also reduced, which in turn allows knee joint movement. However, as soon as the heel is placed back on the ground, stiffening and stabilization in the knee joint area occurs again.

[0118] Figures 19 and 20 show an aid 1 in the form of an arm bandage or arm stocking. The aid 1 in turn comprises a carrier 4, which here is made up of several parts and, on the one hand, has a hand portion, which is, for example, ring-shaped and engages around the palm of the hand. Adjoining this is a connecting portion 24, which extends into an elbow portion 25, which is tubular and engages around the elbow. In the example shown (see Figures 19 and 20), two corresponding connecting portions 24 are provided, one running along the inside of the lower leg and the other along the outside of the lower leg to the elbow portion 25.

[0119] A first fluid chamber 9 is provided on the hand section 23 in the area of ​​the palm, from which two connecting lines 19 branch off, each running along a connecting section to a second fluid chamber 10 on the elbow section 25. The second fluid chambers 10 are arranged on both sides of the elbow joint. The second fluid chambers 10 can have any geometry; they can be designed in the manner of a pad, as shown in Figures 19, 20, or something similar. In any case, if pressure is exerted on the first fluid chamber 9 and the fluid is displaced into the second fluid chambers 10, the fluid pressure there can be increased, which leads to stiffening and the development of, for example, pressure on the area of ​​the forearm in front of the tendon insertion, or something similar, meaning that the aid can be designed as an epicondylitis bandage.However, the use or design, in particular of the geometry of the second fluid chambers 10, is of course not limited to this.

[0120] Fig. 21 shows an aid 1 in the form of an insole 26, wherein the insole 26 again has a textile carrier 4 covered with a more stable sole material. A first fluid chamber 9 is provided, which is arranged in the heel area and which is connected by a connecting line 19 to a second fluid chamber 10, which here is also designed in a net-like or grid-like manner and is arranged in the forefoot area. The second fluid chambers 10 can, of course, also extend into a midfoot area. When the heel is struck, the first fluid chamber 9 is again compressed, and the fluid is displaced forward into the second fluid chamber 10, where the pressure is increased.In this way, the rolling movement can be guided or influenced, whereby, as already described in various previous embodiments, an intermittent pressure is also created here, since when the first fluid chamber 9 is relieved, the fluid is pumped back again and the pressure increase in the second fluid chamber 10 is reduced again.

[0121] In the embodiment according to Fig. 22, which also shows an aid 1 in the form of an insole 26, the first fluid chamber 9 is arranged in the forefoot area of ​​the insole 26, while the second fluid chamber 10 is positioned slightly set back in the midfoot area; both are in turn connected to each other via a connecting line 19. When the foot is placed on the ground, the first fluid chamber 9 is only compressed when the forefoot area is loaded. This leads to an increase in pressure and an increase in volume in the second fluid chamber 10, which actively presses the midfoot arch downward, thus supporting the rolling movement and consequently promoting gait.

[0122] Shown here as an example is the possibility—which of course also applies to the embodiment according to Fig. 21 as well as to all other embodiments—of connecting an external pump 11 to a connection means 12, which here is assigned to the first fluid chamber 9 and which can simultaneously also be designed as a valve device 13. This can be used to adjust the base or basic pressure within the pressure generating device 8 if necessary.

[0123] Fig. 23 shows a schematic diagram of a pressure generating device 8. Shown are the first fluid chamber 9 and a second fluid chamber 10, with further second fluid chambers 10 indicated by dashed lines. Associated with the first fluid chamber 9 is a connection device 12 which also has a valve device 13 comprising an inlet valve 27, via which, if an external pump 11 is connected to the connection device 12, fluid can be supplied from the outside. A connecting line 19 leads from the first fluid chamber 9 and contains a one-way valve 28. The connecting line 19 then continues from the one-way valve to the second fluid chamber 10.This is provided with a drain valve 29 or a pressure relief valve 30, wherein any excess pressure in the second fluid chamber 10 can in principle be released via a drain valve 29, while a pressure relief valve 30 opens when a defined maximum pressure in the second fluid chamber 10 is reached.

[0124] If the inlet valve 27 and the outlet valve 29 are always closed during operation, and the system is therefore sealed, a closed pressure system is provided. However, if fluid, i.e., air, is sucked in via the inlet valve 27 in each cycle and fluid, i.e., air, is blown out via the outlet valve 29 in each cycle, an open system is provided.

[0125] The further second fluid chambers 10 shown in dashed lines are fluidically connected to the second fluid chamber 10 shown in solid lines, so that any pressure present in them can also be released via the release or pressure relief valve 29, 30.

[0126] It is conceivable to design the one-way valve 28 and the drain or pressure relief valve 29, 30 as a combined valve.

[0127] In particular, the second fluid chambers, especially in a grid-like or net-like arrangement of a plurality of second, possibly point-shaped or otherwise shaped, second fluid chambers distributed over a surface, are preferably formed on a chamber component made of a suitable material, which then represents a correspondingly larger-area component. This flat component can be easily attached, e.g., glued, to the textile carrier, so that all fluid chambers or the chamber network can be positioned at once.
