Description

[0001] The invention relates to a compression device for at least one body area, in particular at least one part of an extremity of a user, comprising a portable compression arrangement: a stretch-resistant outer shell on an outer surface facing away from the body area, a flexible inner layer facing the body area made of a liquid-tight material, and a space between the outer shell and an inner wall of the inner layer that is directly or indirectly in contact with the body area and which can be filled with liquid, wherein the compression device further comprises a liquid container connected to the intermediate space via a line.

[0002] Various medical conditions can lead to fluid retention in the human body, for example, in the extremities. One example is lymphedema, a swelling that occurs when excess, protein-rich lymph fluid accumulates in the interstitial tissue. Compression therapy is a well-established treatment for this condition. Another application of compression therapy is in phlebology, where, for example, compression is used to improve venous return in cases of varicose veins. A variety of wearable compression devices, including compression bandages and garments such as compression stockings, have already been proposed in the prior art, often utilizing compressive fabrics.

[0003] A relatively new type of compression therapy was proposed in AT 511 108 B1. This involves a pressure compress or support garment for body parts, particularly the extremities of humans or animals. To generate internal pressure within the compression compress or support garment, a dimensionally stable, liquid-tight outer shell is provided, into which a flexible inner layer made of liquid-tight material is inserted. The space between the outer shell and the inner layer can be filled with liquid and communicates with a liquid reservoir via at least one line. The aim is to counteract the hydrostatic pressure that builds up deeper within the body, starting from the hydrostatic neutral point in humans, which is at the level of the heart. For this purpose, the liquid reservoir is positioned so that the liquid level is located, in particular, at the level of the heart.Similar to a water column, a pressure gradient forms in the lower-lying compression bandage or support garment, counteracting the pressure in the body part as if one were in a swimming pool. This adjusts accordingly with movement / changes in posture, resulting in dynamic compression.

[0004] The invention is based on the objective of opening up a more versatile field of application for hydrostatic compression.

[0005] To solve this problem, a compression device with the features of claim 1 is proposed. Advantageous further developments are described in the dependent claims.

[0006] In a compression device of the type mentioned at the outset, it is provided according to the invention that the compression device has a measuring device for determining a pressure acting at at least one height position along the body area by the fluid in the space between.

[0007] According to the invention, a hydrostatic compression device is used in which a fluid-filled space is located inside a non-stretchable, flexible and / or rigid outer shell. This space is bounded on the side facing the body or skin by the inner wall of an inner layer. The fluid-filled space is connected by means of a tube to a fluid reservoir, which is positioned higher than the body. The tube can, for example, be a flexible hose.Thus, the height of the liquid level in the liquid container, possibly in conjunction with the pressure in a gas bubble within the liquid container, determines the pressure exerted at various height positions within the body region, particularly an extremity such as the leg, foot, or arm, since a continuous liquid system exists that behaves like a column of water due to the pressure acting in all directions. Configurations are conceivable in which the inner layer consists solely of the inner wall, which is liquid-tightly connected to the outer shell, as well as configurations in which the inner layer comprises an inner wall and an outer wall, with the space between them.

[0008] It is proposed to add a measuring device to the compression device in order to determine the pressure at at least one height position along the body area, for example a body part, whereby it is not necessarily necessary to use the measuring device directly at this height position, but the generally known pressure profile within the liquid, which could be water, for example, can be used.

[0009] The measuring device determines the actual pressure currently exerted on the body area, making it possible to precisely adjust the pressure for various applications. This can be achieved, for example, by inducing changes in the hydrostatic system, such as altering the fluid level by changing the height of the fluid reservoir. The device provides information to verify the actual pressure on the body area, thus enabling targeted adjustments. In addition to its use for relaxation, the compression device can be employed in a wide range of applications, including chronic venous insufficiency (especially C3-C6), lymphedema, lipedema, leg ulcers, and wound care, particularly for chronic wounds and open, fragile skin.This allows gaps in care to be closed. Its use in peripheral arterial occlusive disease (PAOD) as well as for the prevention and treatment of postoperative and post-traumatic edema and general swelling conditions is also conceivable.

[0010] All of this is combined with the fundamental advantages of hydrostatic compression, such as the naturally occurring graduated pressure curve, compression that automatically adjusts to the circumference, the ability to achieve high pressures that are not perceived as uncomfortable, and dynamic adjustment. Pressure peaks and constrictions are avoided.

[0011] In a first group of embodiments, the measuring device may include a measuring instrument, either attached to a component or usable hands-free, with a scale that assigns a pressure value and / or a pressure range to a given liquid level. In particular, the scale is arranged such that the liquid level in the container can be assigned to a height on the scale and thus to a pressure value and / or a pressure range. A hands-free measuring instrument is conceivable, which could, for example, be designed as a tape measure or a folding ruler. Several such hands-free measuring instruments for multiple height positions are also conceivable, so that, for example, different measuring instruments can be used depending on the body region to which the compression arrangement is applied and / or depending on the measuring point along the body region.Such a measuring device with a scale can also be arranged on a component of the compression device, for example, as will be explained in more detail later, on a support structure for the liquid container. A measuring device with a scale, readable by a user or another person, can be implemented in a simple way: it can, for example, be associated with the height of the liquid container, specifically the liquid level (i.e., the liquid level), and allows for a suitable, precise adjustment to be made easily, for example, by changing the height of the liquid level above the ground or the body area.

[0012] When the measuring device is mounted on a component, it can be arranged so that the scale is at least height-adjustable, particularly for setting different height positions along the body and / or body regions. This means that if the measuring device is already mounted on a component, for example, a support structure for the liquid container, multiple measuring devices that would always have to measure from the ground or another reference point can be avoided for different height positions and / or different body regions. Instead, it is possible to adjust the height of the measuring device on the component. For example, the measuring device with the scale can be mounted in a guide on which markers corresponding to different height positions and / or body regions are arranged for different positions within the guide.This allows the measuring instrument to be easily adjusted to the appropriate position on the component.

[0013] In a preferred second group of embodiments, the measuring device may include at least one mechanical and / or electronic pressure sensor, in particular arranged at the height position and / or at a fixed height distance from the height position, with an associated display for the pressure measured by the pressure sensor. In this embodiment, a pressure-measuring pressure sensor is used, which may be based on a mechanical and / or electronic principle. The measurement result is displayed by means of a display. In this way, it can be read with a high degree of convenience without any action required by the user or another person. More accurate measurements are also possible. It should be noted that a combination of measuring device and pressure sensor is also possible, for example, for mutual plausibility checks and / or for using the measuring device in the event of a pressure sensor failure.

[0014] In a specific embodiment, the pressure sensor can be arranged on or in the space between the layers, or the inner layer can have an outer, liquid-tight wall facing the outer shell, with the pressure sensor located on this outer wall. In this case, the measurement is taken directly on or in the space between the layers. For example, the pressure sensor can be positioned at the desired height, or at a fixed or definable height relative to this height. Advantageously, the height, and thus the potentially derived position of the pressure sensor, can be located, for example, at the ankle of a leg and / or foot, and / or selected according to standard measurement points for which compression levels are specified in other compression products. For example, when using the RAL standard, the height can be selected at measurement point B.Of course, multiple height positions and / or multiple pressure sensors can also be used, for example, measuring points B, B1, C and D can be covered.

[0015] In a particularly advantageous embodiment in this context, a transparent window is provided in the outer shell, especially adjacent to the pressure sensor, behind which the display device coupled to or integrated into the pressure sensor is located. This allows the pressure to be easily identified and displayed at the height where it is measured. The display device can be an electronic device, such as a display or the like; however, a suitable embodiment can also provide for the use of a mechanical pressure sensor with an associated mechanical display device, which are mechanically coupled. In this way, no power supply is required for the compression assembly, yet pressure indication is still possible. Furthermore, the design is mechanically simple.

[0016] In this context, and more generally, it can be advantageous for the display device to be designed to indicate the measured pressure within one of several pressure ranges, which correspond in particular to compression classes. These pressure ranges can be color-coded. Specifically, for example, the colors green, yellow, orange, and red can be used for four compression classes, especially compression classes I, II, III, and IV according to RAL. Of course, the color codes can also refer to other internationally used standards for classifying compression pressure values. In the case of a mechanical display device, which can be coupled with a mechanical pressure sensor, the display device can, for example, comprise a rotating element with the corresponding colors in such a way that the pressure currently measured by the pressure sensor is indicated by one or two colors visible through the transparent window.In general, such color coding is easy to read and therefore intuitively understandable. The display and the pressure sensor can also be at least partially integrated. For example, the pressure sensor can be a film that changes color depending on the measured pressure, which is visible, for example, through the transparent window.

[0017] In a generally advantageous embodiment of the present invention, as already indicated, it can further include a carrier device for the liquid container, wherein the carrier device is wearable by the user on the body, in particular as a shoulder, chest, hip, and / or back carrier with at least one carrying strap, or the carrier device comprises a, in particular mobile, self-supporting stand. The body-worn carrier device can, for example, be buckled to the body and / or slung over or around the neck. A relatively high position on the body, for example on the shoulder, chest, and / or back, is particularly preferred. However, a hip belt and / or belt or similar device is also conceivable. To secure the body-worn carrier device, it can, for example, have a fastening system, for example, comprising at least one hook-and-loop fastener.Using a body-worn device has the advantage that no additional equipment needs to be carried when the user moves. However, a body-worn device may limit the range within which the fluid level can be adjusted.

[0018] Therefore, a support structure with a self-supporting stand can also be used, preferably one that is mobile, for example, by using wheels on a suitable, low-lying wheel carrier or foot element, the design of which, as well as the arrangement of the wheels, preferably prevents tipping as much as possible. Depending on the height of the stand, greater heights for the liquid container and thus the liquid level can be achieved. For example, the stand can have a height of at least 1.5 m, preferably at least 2 m, or be adjustable to such a height. The stand can have a container support for the liquid container, for example, a hook, which is preferably provided at the upper end of the stand. It is particularly advantageous for the stand to be an IV stand or to be designed like one. Given the preferred mobility of the stand, it can be moved with the user.

[0019] In a particularly advantageous further development, the compression device can include a manually and / or automatically controlled actuator for changing the height of the fluid level in the fluid reservoir relative to the body area and / or for changing the pressure exerted by an air cushion provided within the fluid reservoir. The height of the fluid level in the fluid reservoir relative to the body area can be varied, in particular, by changing the height of the fluid reservoir relative to the body area. In this way, a change in pressure can be achieved automatically without the need for manual operation. A particular advantage, however, is the possibility of also implementing pressure variations to improve well-being and / or the therapeutic effect.

[0020] Specifically, the compression device can include a control unit designed to actuate the actuator to implement a predefined pressure change profile in the body area and / or to regulate the pressure to a setpoint based on measurements from a pressure sensor. This design is particularly advantageous for cyclical and / or regular pressure changes, for example, according to a waveform such as a sine wave or sawtooth wave. In this way, the control unit is configured to generate a specific, predefined pressure profile by actuating the actuator. This makes it possible, for example, to functionally replicate a massage, which is used in many applications. A sine wave profile has proven particularly effective in this regard, resulting in a pulsating pressure profile.

[0021] Alternatively or additionally, it is also possible to use the measurement results from a pressure sensor to automatically regulate the pressure to a specific desired value. This allows, for example, compensation for changes in altitude caused by user movement, and similar situations. A pressure that is as constant as possible, or a pressure profile with a consistent level, can be achieved for optimal comfort and / or therapeutic success.

[0022] The change can be effected by actuating at least one control element of the compression device assigned to the control unit and / or an external device communicating with the control unit, in particular a mobile device, and / or, in the case of cyclic and / or regular pressure changes, the device can be switched on and off and / or parameterized. A simple control unit can be used for this purpose, for example, with one control element for "starting up" and one for "shutting down." One or more control elements can also be provided for cyclic and / or regular pressure changes. Control elements can also be provided to set the pressure to which the device is regulated. In particular, an application ("app") can be used on a mobile device communicating with the control unit to conveniently make the corresponding settings.

[0023] In a specific further development, it may be provided that the actuator for changing the height of the liquid container is designed on a support structure that carries the actuator. In particular, a holder for the liquid container may be guided in a guide, especially a linear guide extending at least partially vertically, of the support structure. Here, for example, the guide of the actuator may extend along a support belt extending at least partially vertically. For example, the largest possible proportion of the vertical extension of the support structure to be worn on the user's body can be utilized by guiding the liquid container along a corresponding support belt by means of the actuator, especially in the appropriate guide.

[0024] Generally speaking, the actuator can comprise a lifting linkage and / or a gear drive and / or a motor and / or a rotary knob as a control element for manual operation of the actuator. Such known, simple mechanical designs, as well as other possibilities, can be used expediently within the scope of the invention.

[0025] Regarding a support structure that includes a stand, the stand may be designed to have a vertical component along which the liquid container can be moved by means of the actuator, and / or whose height can be adjusted by means of the actuator, and / or on which the measuring instrument with the scale is arranged. In this case, a lifting linkage, for example with a rotary knob and / or a motor, can be used to particular advantage. This allows the long vertical extension of the stand to be utilized as fully as possible. If the vertical component itself is height-adjustable, for example in the form of a telescopic rod, the adjustability or interchangeability of the measuring instrument with the scale can also be linked to the current height setting of the vertical component.

[0026] In a further development of the invention, a valve can be provided in the flow control line, which can be throttled by means of a throttling device. A control device is configured to actuate the throttling device to set a degree of throttling that results in a pressure profile at the body area that pulsates with repeated movements of the user while the compression device is applied. It is therefore conceivable to also produce a pulsating pressure profile by actuating a corresponding throttling device of the valve in response to a movement of the user. In principle, it is also possible to connect the fluid reservoir to the intermediate space via two lines, each of which has a valve in which a throttling device is provided.The throttling device is thus adjusted in such a way that a pulsating pressure profile can be generated by regulating the backflow through rhythmic movement. Here, measured values ​​from the measuring device, which includes at least one pressure sensor, can again be used to appropriately regulate the degree of throttling based on these measurements.

[0027] In a suitable further development, the compression garment can also include a stabilizing element to hold the outer shell and / or the inner layer in place on the body area and / or extending along the body area. Such a design is always useful when, for example, the outer shell lacks sufficient inherent stability and could slip off and / or unintentionally change its shape. This is the case, for instance, when the outer shell is at least partially formed by a wrap and / or a bandage or the like. The stabilizing element can, for example, be L-shaped, with the lower leg of the L supporting the outer shell from below, while the longer, vertical leg holds it in place. In particular, this prevents compression or pinching when applying the compression garment to the body area.

[0028] It is particularly advantageous if, in the case of a body area encompassing toes and / or fingers, the space between the compression elements (or the inner layer or even the compression arrangement itself) extends around individual toes and / or fingers. In particular, the compression arrangement can be designed, at least partially, and especially entirely, in the manner of a glove or a toe shoe. In this way, compression treatment is advantageously made fully accessible to the fingers and / or toes. In particular, this can, for example, make it possible to treat chemotherapy-induced peripheral neuropathy (CIPN) and similar conditions with the compression device according to the invention.

[0029] A further development of this design may provide that the compression assembly includes a fastening means for detachably attaching the inner layer to the outer shell. Preferably, the inner layer may have the inner wall and the outer wall to define the space between them. It is also conceivable, in principle, to attach an inner layer consisting only of the inner wall to the outer assembly in a detachably sealing manner. In this way, the inner layer can be made replaceable, either to provide inner layers of different designs, for example, as part of a compression system, or to replace a damaged inner layer, for example, one whose sealing has been compromised, and thus to achieve a repair. Generally speaking, this increases flexibility and / or improves maintainability. A compression system with multiple outer shells and / or inner layers is also conceivable.The fastening of the inner shell to the outer shell can be achieved, especially in the case of inner shells having an inner wall and an outer wall, for example by means of Velcro fasteners, detachable snap-fit, clip, hook-in connections and the like.

[0030] Preferably, a pocket for inserting a cooling element, in particular a cooling pack, can be provided on the liquid container to cool the liquid. In this way, the liquid, for example water, an isotonic liquid, or the like, can be cooled, resulting in a pleasant and, in many cases, therapeutically beneficial additional cooling effect. For example, the pocket can extend across the front and / or back of the liquid container, in particular covering at least substantially the entire front and / or back, for example, at least 90%. This ensures that the cooling effect is applied over a large area. Furthermore, the liquid container is easily accessible, allowing for simple and convenient replacement of the cooling element.In principle, it is also conceivable to provide such a pocket additionally or alternatively on the compression assembly, for example between the outer shell and the inner layer comprising the inner and outer walls. However, this is less preferred.

[0031] A particular advantage is that the compression device, or at least its outer shell, can be incorporated into an orthopedic garment, especially an orthopedic walker boot, shoe, stocking, glove, or trousers. For example, the compression device can be integrated into an orthopedic walker / walker boot or shoe, which are examples of the generally conceivable possibilities for dimensionally stable outer shells. With such orthopedic walker boots and / or shoes, the compression device can be used, for instance, after Achilles tendon and / or ankle ruptures, fractures, and / or corresponding surgeries to stabilize and compress the affected area. In particular, such a walker boot is also suitable for diabetics, as it provides pressure relief and prevents pressure peaks across the entire foot or sole.In this context, it would also be conceivable to provide the compression arrangement or the inner layer as a pure insole.

[0032] Furthermore, it is also possible to integrate the compression device with an orthosis, such as an ankle orthosis and / or a knee orthosis, to provide targeted compression after injuries, traumas, and / or surgeries, particularly in conjunction with the aforementioned cooling, along with the other functions of an orthosis. Orthoses, too, can be understood as dimensionally stable outer shells.

[0033] As previously mentioned, it is also conceivable to provide the outer shell using a wrap and / or bandage, which can incorporate a suitable closure mechanism or system (for example, straps with Velcro fasteners or lacing). A special cut or construction tailored to the inner layer can be created. In this context, a combination with detachably attached inner layers, featuring an inner and an outer wall, is particularly advantageous for creating highly adaptable compression arrangements that can also be modular and / or expandable. A stabilizing element can also be beneficial in wraps and / or bandages, for example, to prevent compression during application or entry.

[0034] It should also be noted that the compression device can include a flexible and / or stretchable undergarment, which can be worn beneath the compression garment to further increase comfort, especially with inner walls made of plastic or similar materials. This can create more breathing space for the user's skin and improve the overall feel. However, similar effects can also be achieved through appropriate design of the inner wall's skin-facing surface.

[0035] Further advantages and details of the present invention will become apparent from the exemplary embodiments described below and from the drawings. These show: Fig. 1 a schematic diagram of essential components of a general embodiment of a compression device according to the invention, Fig. 2 a first embodiment of a measuring instrument with a scale, Fig. 3 a second embodiment of a measuring instrument with a scale, Fig. 4 a third embodiment of a measuring instrument with a scale on an exemplary, schematically shown support device, Fig. 5 a first embodiment for the arrangement and design of a pressure sensor, Fig. 6 a second embodiment for the arrangement and design of a pressure sensor, Fig. 7 a first specific embodiment of a compression arrangement, Fig. 8 a second specific embodiment of a compression arrangement, Fig. 9 a third specific embodiment of a compression arrangement, Fig. 10 a fourth specific embodiment of a compression arrangement, Fig.Fig. 11 a fifth specific embodiment of a compression arrangement with a first specific embodiment of a support device, Fig. 12 a sixth specific embodiment of a compression arrangement with a second specific example of a support device, Fig. 13 a third specific embodiment of a support device, Fig. 14 a seventh specific embodiment of a compression arrangement with a fourth specific example of a support device, and Fig. 15 a fifth specific embodiment of a support device with a stand.

[0036] Fig. 1 Figure 1 shows a schematic diagram of a general embodiment of a compression device 1 according to the invention. The components are initially depicted abstractly before more specific embodiments are explained in the following figures. Nevertheless, the abstract representation is sufficient to explain various basic principles, configurations, and functionalities of the compression device 1 according to the invention, which may also be present in the embodiments described below. Where appropriate, features can therefore be transferred between the embodiments described here.

[0037] The compression device 1 comprises a compression assembly 3, wearable on a body region 2 of a user (only indicated here), which includes an outer shell 4 and an inner layer 5. The outer shell 4 is stretch-resistant and can be dimensionally stable or flexible. The inner layer 5 is flexible and, in this case, has an inner wall 6 facing the body region 2 and an outer wall 7 facing the outer shell 4, between which a space 8 is formed. The space 8 is sealed and connected to a liquid container 10 via a line 9, in particular a hose. In the ready-to-use state or during use, the space 8, the line 9, and the liquid container 10 form a sealed, hydrostatic system, at least at the bottom, which is connected and filled with a liquid 11, for example, water. The liquid in the liquid container 10 reaches a liquid level 12.Fluid level. According to the laws of physics, the fluid level 12 determines the pressure conditions in the space 8, where the fluid container 10 is positioned higher than the compression device 3. This results in a graduated compression profile, as the compression on the body area 2 increases from top to bottom depending on the level of the fluid 11 above the corresponding position. If an air cushion 13 in the fluid container 10 is pressurized, the pressure in the space 8 can be increased accordingly.

[0038] The liquid container 10 comprises a suspension device 14 by means of which the liquid container 10 can be attached to at least one support device 15 of the compression device 1, here by way of example and without limitation to a container support 16 shown as a hook. Furthermore, the liquid container 10 also includes a pocket 17, arranged, for example, on its front or rear, for receiving a cooling element 18 for cooling the liquid 11. Several such pockets 17 may also be present, for example, both on the front and on the rear.

[0039] In order to be able to adjust a desired compression along the body area 2 as precisely as possible, the compression device 1 includes a measuring device 19 with which the pressure in the space 8 can be determined at at least one height position along the body area 2.

[0040] The measuring device 19 can initially include a measuring instrument 20 with a scale 21 on which a user can read the pressure at at least one height position. For this purpose, the measuring instrument 20 is provided manually or permanently, for example, attached to a component, and arranged such that the current fluid level 12 can be assigned to a value for pressure or compression on the scale 21. Several measuring instruments 20, each with different scales for different height positions and / or body regions 2, can be provided. Furthermore, a measuring instrument 20 with a scale 21 attached to a component can be vertically adjustable on the component to accommodate specific height positions and / or body regions 2, as well as changes to the component itself.

[0041] Additionally or alternatively, the measuring device 19 can also include at least one pressure sensor 22, which mechanically and / or electrically measures the pressure at the height position and / or at a position whose height difference from the height position is determined or determinable. A display means 23 can be associated with the pressure sensor 22, on which the pressure measured by the pressure sensor 22 can be displayed. In addition to a numerical display, a color-coded display is also conceivable, depending on the pressure range, which corresponds in particular to a compression class, in which the measured pressure lies. For example, the colors green, yellow, orange, and red can be used for compression classes I, II, III, and IV according to RAL. In this context, the at least one height position for which the pressure is determined preferably corresponds to a measuring point for which the compression class is defined, for example, according to RAL, measuring point B, B1, C, and / or D.

[0042] Particularly when the measuring device 19 includes a pressure sensor 22, but also for other purposes, the compression device 1 can also include a control device 24, which, for example, can process measured values ​​from the pressure sensor 22. Furthermore, the control device 24 can influence the pressure in the space 8 to set a desired compression or compression profile. For this purpose, the compression device 1 expediently includes an actuator 25, which is shown here by way of example as part of the support device 15 and can change the height of the liquid reservoir 10 on the support device 15. An alternative or additional actuator 25 can also influence the pressure of the air cushion 13 to make a pressure adjustment. Accordingly, the control device 24 is designed here to regulate to a specific pressure depending on the measured values ​​of the pressure sensor 22.

[0043] Furthermore, the control unit 24 is also configured to implement a predefined pressure change profile in the body area 2. The pressure is cyclically or regularly changed by appropriately controlling the actuator 25, preferably according to a wave function such as a sine function, in order to simulate a massage. For example, the actuator 25, which influences the height of the liquid level 12 relative to the body area 2, can be controlled to raise and lower, for example, the liquid container 10.

[0044] Furthermore, another possibility for influencing the control unit 24 is provided if a valve 26 with a throttling device 27 is installed in line 9. By adjusting the possible backflow into the fluid reservoir 10 during user movement, for example while walking, a dynamic change in pressure can also be parameterized.

[0045] The control unit 24 can be assigned an operating unit 28 with at least one operating element 29. Operating elements 29 can be used to adjust the pressure in general, for example, to actuate the actuator 25 to change the liquid level 12 or the pressure of the air cushion 13 (increase or decrease). However, at least one operating element 29 can also be used to activate and / or deactivate the pressure change according to the pressure change profile and / or to parameterize it.

[0046] The control unit 24 can also communicate wirelessly, as indicated by the double arrow 30, with an external device 31, here a mobile device 32 (for example, a mobile phone), whereby an application 33 can be executed on the mobile device 32, which allows operation of the compression device 1 as described for the control device 28 and also permits the mobile device 32 to be used as a display device 23 for the measured pressure of the pressure sensor 22. Wireless communication can take place, for example, via Bluetooth, WLAN, and the like.

[0047] Particularly when the outer shell 4 is not inherently stable or not sufficiently so, the compression device 1 can also include a stabilizing element 34 that holds and stabilizes the outer shell 4 against the body area 2. This is especially advantageous when the outer shell 4 is formed by a wrap and / or a bandage. The L-shaped stabilizing element 34 shown here as an example can then engage the outer shell 4 from below or run laterally along the foot, while the longer, vertical leg of the L stabilizes outwards. Specifically, the longer leg of the L can stabilize the calf area to prevent compression or crushing when stepping into the outer shell 4. In particular, several such stabilizing elements 34 can be provided, or the stabilizing element 34 can comprise several sub-elements.

[0048] The compression device 1 can further provide a detachable fastening of the inner layer 5 to the outer shell 4 with corresponding fastening means 35, which are only indicated here. In this way, the inner layer 5 and / or the outer shell 4 can be replaced, for example in the event of damage or within a compression system with several inner layers 5 and / or several outer shells 4.

[0049] Fig. 2 Figure 1 shows a first concrete embodiment of a measuring instrument 20 with a scale 21. The measuring instrument 20 is designed as a measuring tape 36, with which the fluid level 12 can be measured, for example, from the floor with the user standing and / or from a specific position on body area 2 and / or the compression arrangement 3. The measuring tape 36 is extendable. Both length markings (in centimeters) and pressure markings (in mmHg) are indicated on the scale 21.

[0050] Fig. 3 Figure 2 shows a second specific embodiment of a measuring instrument 20 with a scale 21, in which the measuring instrument 20 is designed as a folding rule 37. As is generally known, the folding rule 37 has a joint 38 with which the various segments of the folding rule 37 can be pivoted relative to each other.

[0051] Fig. 4 Figure 1 shows a third specific embodiment of a measuring instrument 20 with a scale 21, which is slidably arranged on a vertical component 38 of a stand of a support device 15. For this purpose, the vertical component 38 has a corresponding vertical guide 39. The liquid level 12 can be clearly assigned to a value on the scale 21. Also shown schematically is an actuator 25, with which the height of the liquid container 10 containing the liquid 11, which is arranged on a corresponding arm 40 (e.g., pivotable or fixed at an angle), can be changed, while the measuring instrument 20 remains stationary and can thus continue to be used. In embodiments where, for example, the height of the vertical component 38 is adjusted at a lower point, the slidability of the measuring instrument 20 can be used to compensate for this change in height.

[0052] Fig. 5 Figure 1 schematically shows a first embodiment of the arrangement of the pressure sensor 22 and its associated display element 23, which allows for a completely mechanical design without its own electrical power requirement. The inner layer 5 comprises the inner wall 6 and the outer wall 7, with the outer shell 4 having a bulge with a transparent window 42 in the area of ​​the height position 41. The pressure sensor 22 is arranged on the outer wall 7, between the inner layer 5 and the outer shell 4, and is mechanically designed. Pressure exerted on the pressure sensor 22 is transmitted by it, via mechanical coupling, to the display element 23, which is visible from the outside behind the transparent window 42. Specifically, the display element 23, which is also mechanically designed, has a rotating body 43 on which areas of different colors are applied, for example, green, yellow, orange, and red.As the pressure detected by the pressure sensor 22 increases, the rotating body 43 changes from green to red, so that the colors displayed behind the transparent window 42 clearly represent the pressure range and thus the compression range, in particular a corresponding compression class. In a preferred, flat-design embodiment, the pressure sensor 22 and the display medium 23 can also be integrated, in that the pressure sensor 22 includes a film that also acts as a display medium 23 and changes its color depending on the pressure applied.

[0053] Fig. 6 Figure 1 shows a similar, second embodiment in which the pressure sensor 22 is electromechanically designed and transmits its measured values ​​to the control unit 24 by means of an associated communication device 44.

[0054] In both cases, it is also conceivable to arrange the pressure sensor 22 in direct contact with the liquid 11, for example at least partially in or adjacent to the space 8.

[0055] Fig. 7 Figure 1 shows a first concrete embodiment of a compression arrangement 3 for the forearm and hand as body region 2, which is designed overall in the manner of a glove 45. The glove 45 evidently has sections 46 for the individual fingers 47. In other words, the space 8 extends around the individual fingers 47, so that each finger is individually subjected to compression. A corresponding design is also possible for the foot or toes.

[0056] Fig. 8 shows a second embodiment of a compression arrangement 3, where, in contrast to the Fig. 7 as a mitten 49, therefore the space 8 does not individually enclose the fingers 47.

[0057] Fig. 9 Figure 3 shows an embodiment of a compression arrangement 3 in a third embodiment as shorts 50, which thus act on the hip area 51 of the user 52 as body area 2. As corresponding Fig. 10 As shown, a design for hips, legs and feet as body area 2 is also possible in a third embodiment in the manner of pantyhose 53.

[0058] Fig. 11 shows, using a fifth embodiment of a compression arrangement 3, that the compression arrangement 3 can also be designed as a stocking 54 for only one leg 55 of the user 52.

[0059] Shown in Fig. 11 Also shown is a first concrete embodiment of the support device 15, in this case as an upper arm cuff 56 to which the liquid container 10 is attached. For the sake of clarity, embodiments are conceivable, not shown in detail, in which the liquid container 10 can be moved up and down along a corresponding support belt by means of the actuator 25 on the upper arm cuff 56, for example in a linear guide.

[0060] Fig. 12 Figure 6 shows a sixth embodiment of a compression arrangement 3, designed as a lower leg-foot bandage 57 or a lower leg-foot wrap. The bandage 57 or wrap holds the inner layer 5, which can be attached at the upper end, securely and firmly. The bandage 57 or wrap is closed by means of appropriate fastening devices of a closure system, here straps 58 equipped with hook-and-loop fasteners. In the case of less inherently stable bandages and / or wraps, the already mentioned features can be used to further improve the stability of the bandages. Fig. 1 The discussed stabilizing elements 34 will be used.

[0061] Fig. 12 Figure 15 also shows another conceivable embodiment of a carrier device 15, which can be worn on the user's body 52. ​​A container pouch 61, accessible via a zipper 60, is attached to a belt 59 as a hip carrier and serves as a container carrier. The liquid container 10 is arranged in this pouch. The container pouch 61 can also serve as a pocket 17 for the cooling element 18, for example, by having a compartment for it. In such a case, the actuator 25 is preferably designed to increase the pressure exerted by the pressure pad 13, since the height is only slightly or hardly variable.

[0062] Fig. 13 Figure 15, again using the bandage 57 or wrap as a purely exemplary illustration, shows a third possible embodiment of a carrier device 15, which in this case is designed as a shoulder carrier 62 and can therefore be worn over the shoulders. The fluid container 10 is coupled via the actuator 25 to a carrier belt 63 that extends at least partially vertically and has a corresponding linear guide 64. The fluid container 10 can thus be adjusted in height along the carrier belt 63, in particular controlled by the control device 24, but also manually if necessary.

[0063] Fig. 14 Figure 7 shows a seventh concrete embodiment of a compression arrangement 3, in which the outer shell 4 is formed by a dimensionally stable Walker Boot 60. Alternative, conceivable orthopedic garments of this type are orthopedic shoes. It is also conceivable, although not shown in detail, that the outer shell 4 could be formed by an orthosis, for example, a knee orthosis.

[0064] The shoulder support 62 is a fourth embodiment of a support device 15, modified in that the liquid container 10 can be manually fastened at a certain height by means of a buckle arrangement 70, for example, by being moved and clamped.

[0065] It should be noted that, in principle, any combination of carrier devices 15 and flexible or dimensionally stable compression arrangements 3, as described, is conceivable, as long as the liquid container 10 can be arranged above the compression arrangement 3. For example, a carrier device 15 with an actuator 25 can also be provided in a walker, and so on.

[0066] Fig. 15 Finally, a fifth embodiment of a support device 15 is shown, in this case in the form of a stand 65, specifically an IV stand. This stand has a base element 66 with wheels or casters 67, making it mobile. The central vertical component 38 is telescopically adjustable in height by means of the actuator 25 or one of the actuators 25, in this case automatically operated via control elements 28. A rotary knob for manual height adjustment is also conceivable. However, in all other respects, Fig. 4 The measuring instrument 20 with the scale 21 may be provided to be slidable on the upper part of the vertical component 28, also to compensate for height adjustments of the vertical component 28. Alternatively or additionally, as in Fig. 4 As shown, an actuator 25 is also provided in the area of ​​the container carrier.

[0067] Finally, it should be noted that the connecting element 68 visible in the figures also allows connection to various compression arrangements 3 or their intermediate space 8. The line 9 on the side of the liquid container 10 can also be designed to be removable in order to further improve the modularity shown and / or to facilitate the exchange of liquid 11. In principle, however, the liquid 11 can remain in the hydrostatic system for several treatment cycles.
