Description

The invention is concerned with a stimulation unit, in particular for an orthosis or a cuff, with a plurality of stimulation fields, wherein the stimulation insert can be attached to a part of the body when it is used.

From the CA 1085251 A2 a cuff for applying locally changing pressures to the extremities of a patient is known. This is achieved in that the cuff has a chamber which is divided into several sub-chambers which are connected to one another via channels. The lower chambers can be pressurized with compressed air. The diameter of the channels decreases from the inlet of the compressed air to sub-chambers further away from the inlet. This means that the pressure in the sub-chamber directly adjoining the inlet is higher than in the subsequent sub-chamber, etc. This configuration creates a rolling effect in which, starting from the compressed air inlet, the sub-chambers fill up one after the other due to the decreasing pressure gradient, creating a kind of massage movement in a direction away from the compressed air inlet. This stimulates the flow of blood from the compressed air inlet to the last subchamber. If the direction of the decreasing pressure gradient points towards the heart, this will provide relief from thrombosis.

The object of the invention is to present an alternative device that can be attached in particular in the area of a joint and that uses both compressed air as the stimulation medium and is generally suitable for other stimulation media.

The object is achieved by a stimulation insert with the features of claim 1. The stimulation insert according to the invention has a plurality of stimulation fields which are passed through starting from a feed field which is connected to at least one feed element.

Such a plurality of stimulation fields arranged one behind the other is referred to as a row in the context of this application. There are at least two of these rows of stimulation fields which are arranged in relation to one another in such a way that there is a free space between them, which is used to receive a joint or to attach it along a limb. This makes it possible to place the stimulation insert around a joint and to use the rolling effect not in the area of the joint, but around it, whereby the soft tissue present there can be acted upon with the rolling effect mentioned in the task. At the first ends of the respective row, there is a supply line field which is connected to at least one supply line element for feeding in a stimulation medium. In an advantageous embodiment, all rows have a single, common feed element. Stimulation media are understood to mean those media that can achieve a rolling effect. These are in particular - but not exhaustively - the compressed air used in the above-mentioned prior art according to the Canadian patent or other gases, electrical stimulation current, as is known, for example, in rehabilitation therapy after a sports accident, but also liquids, like water or oil. According to the invention, the stimulation fields are connected to one another in such a way that the stimulation medium runs through them starting from the feed element to the respective second end of the rows, whereby the desired rolling effect is achieved. What this connection looks like depends on which stimulation medium is used. The subclaims specify specific embodiments for the stimulation media compressed air and electric current.

An advantageous development of the invention provides that the second ends of the rows are adjacent to one another. This creates a closed free space without stimulation fields, which can be placed on the joint and the effect takes place in a ring around the joint. In particular, a circular shape can be achieved for the free space, but also other shapes, such as, for example, that of an ellipse or a lens.

The object is also achieved by a stimulation insert with the features of claim 2, which, in contrast to the aforementioned, is designed in such a way that a second or further row does not necessarily have to be present. The at least one row is formed in a spiral around the space free of stimulation fields for receiving a joint or for attachment along a limb and the stimulation fields are connected to one another in such a way that the stimulation medium runs through them starting from the feed element at one end to the other end of the row. This gives a further form which, with a massage effect, is suitable for treating the respective body area.

The object is also achieved by a stimulation insert with the features of claim 3, which, unlike the two previously mentioned, is designed so that the at least one row is circular around the space free of stimulation fields for receiving a joint or for attachment along a limb and the stimulation fields are connected to one another in such a way that the stimulation medium emanates from them runs from the supply element in both directions of the series. This gives a further form which, with a massage effect, is suitable for treating the respective area of the body.

The object is also achieved by a stimulation insert with the features of claim 4, which, unlike the aforementioned, is designed so that it has only one row that is bent around the space free of stimulation fields for recording, and the stimulation fields of one End to the other end. Such a configuration is particularly suitable for enclosing one side of an ankle.

The object is also achieved by a stimulation insert with the features of claim 5, which, unlike the aforementioned, is designed so that a row is straight and has a recess as a free space for receiving a joint or for attachment along a limb.

An advantageous development of the invention provides that there is another stimulation insert according to the invention, a common feed line element for both stimulation inserts being arranged in a web which extends between the two stimulation inserts. This means that both sides of an ankle can be covered at the same time and the duration of the treatment is shortened; At the same time, the supply line centrally between the two stimulation inserts ensures that when compressed air is used as the stimulation medium, a symmetrical flow through the two stimulation inserts takes place. With such a use of compressed air as a stimulation medium, a further advantageous development is to be seen in the fact that an air outlet is also formed in the web, which is connected to the last stimulation field of each stimulation insert. As a result, the compressed air can be sucked out of each individual stimulation insert after it has passed through. A further advantageous development in the case of two stimulation inserts provides that the two stimulation inserts have the same structure and are arranged mirror-inverted at the two ends of the web connecting them. As a result, when used in the area of the ankle, good encirclement of both sides of the ankle on one foot can be achieved.

An advantageous development of the invention provides that there are exactly two rows. Such a design can be easily produced and easily attached to the area to be treated.

Another advantageous further development of the invention provides that the size and shape of the free space is matched to the type and intended use of the orthosis or cuff. The number of stimulation fields per row and the associated length of the rows depends on the joint or limb on which the stimulation insert is to be used.

The shape and size of the free space between two adjacent rows of stimulation fields also depends on this. For example, for a stimulation insert in the region of the knee joint, the free space for receiving the knee joint is greater than in the case of a stimulation insert for the region of the elbow joint. In addition, the lengths of the individual rows are longer for a stimulation insert for the knee joint than for an elbow joint.

Another advantageous development provides that all rows have a common feed element. This saves parts and reduces costs, since only a single supply line element needs to be present. In addition, it is also not necessary to have to synchronize between two separate supply line elements - if these should be present in another alternative - in order to achieve synchronization of the rolling movement in the individual rows.

A preferred choice for the stimulation medium is electrical current, in which case the stimulation fields are electrodes. The stimulation current methods known in particular in the field of rehabilitation therapies can be used here, which can be used even more efficiently by means of a stimulation insert according to the invention than has been done so far in rehabilitation therapies, where only two electrodes are regularly glued to the skin and then between these two electrodes Electricity flows.

An advantageous development of the invention provides that the electrodes are connected via a cable, in particular a flat ribbon cable, to a microprocessor which controls the power supply to the individual electrodes. With such a microprocessor, which is responsible for controlling the individual electrodes and which are connected to the microprocessor via cables, many different programmed process sequences can be carried out, with it being possible to choose between these very easily, for example, through a menu on a display or by means of a switch on the device can be adapted to the required form of therapy.

An advantageous development of the invention provides that between the microprocessor and Electrodes a multiplexer circuit available. In addition, each individual electrode can be controlled very easily by the microprocessor, so that each individual electrode can be controlled individually both in terms of time and its amplitude and waveform. The time delays can also be caused by the microprocessor or switching transistors.

Another advantageous development of the invention provides that the stimulation insert has a portable accumulator as an energy source. It is thus possible to operate the orthosis or cuff into which a stimulation insert according to the invention is inserted independently of an electrical energy source that is attached to a fixed location, for example a socket. In view of the fact that a stimulation insert according to the invention has only very low power consumption, such accumulators can be kept very small and only have a low weight, so that there are no major hindrances for the wearer of an orthosis or cuff. This makes it possible to use an orthosis or cuff with a stimulation insert according to the invention in dynamic use, even when changing location - unlike when moving on a treadmill or an exercise bike, for example, i.e. also during activities such as jogging, household chores, car trips use; also for therapy at home. Alternatively, the regular power grid with 220 V can be used as an energy source if no location independence is required. The stimulation insert then has a plug that can be plugged into a regular socket.

An advantageous development of the invention provides that a time delay element is arranged between each adjacent electrode.

This provides a very simple solution for generating the rolling effect according to the invention, so that a stimulation takes place starting from the supply element in a chronological sequence towards the second end of each row. The time delay elements are preferably designed as capacitors and / or a chain of shift registers with switching transistors controlled thereby.

As an alternative to electrical stimulation, compressed air can also be used as the stimulation medium. In such a case, the stimulation fields are air chambers and the feed element is an air inlet, which is preferably designed as a connection nipple for an air hose. In a preferred embodiment, the last air chamber of at least one of the rows is connected to an air outlet - which can also be combined collectively for all rows in one. The use of compressed air in the stimulation insert according to the invention has the advantage that it can be constructed very simply and the rolling effect is comparable to that of a massage or lymphatic drainage, where pressure is also exerted on the treated tissue - unlike when using Stimulation current is the case.

In an advantageous development of the stimulation insert according to the invention when using compressed air as the stimulation medium, adjacent air chambers are connected to one another via an air passage. Such a structure is very easy to implement and inexpensive to manufacture. In an advantageous development of the invention, the air passages have a clear width of 2 to 5 mm, preferably 3.5 mm. This creates a rolling movement that is good in terms of its therapeutic effect. Two foils, each with a thickness of, for example, 0.4 mm are preferably welded to one another, the weld seam width being approximately 1-2 mm.

An advantageous development of the invention provides that all rows are connected to a common air outlet. In this way - as already stated above for the air inlet - a simplification of the structure of the invention is achieved and, moreover, additional parts are saved. The air outlet is preferably arranged adjacent to the air inlet. The stimulation insert according to the invention can thus be made very compact. As an alternative to the air outlet, a sensor connection can also be present at its position, which can be connected to an air pressure sensor for measuring the air pressure at the end remote from the air inlet.

A further advantageous development of the invention provides that there is an inlet valve in the feed element and an outlet valve or a sensor connection in the air outlet. This enables good control of the air pressure in the rows, which leads to the best possible therapeutic effect due to the rolling effect that can be precisely defined as a result. The outlet valve is preferably designed in such a way that it opens when a predeterminable air pressure is exceeded in the chambers. Since the outlet valve / sensor connection is connected to the last chamber of each row, i.e. the air chamber last filled with compressed air, the final air pressure can be determined (with regard to the outlet valve) or measured (with regard to the sensor connection), which is individually tailored to the therapy required and the area around the joint to be treated is set.

Alternatively, the inlet valve and outlet valve / sensor connection cannot be included in the Be arranged supply element or in the air outlet, but in its periphery outside of the stimulation insert in an air hose or on a pump that is connected to the stimulation insert during operation.

An advantageous development of the invention provides that the air pressure at the inlet valve is constant between 0.3 and 2.0 bar, preferably 0.5 bar, or the air pressure can be regulated. It is clear to the person skilled in the art that the pressures given throughout the application are given above atmospheric pressure.

An advantageous development of the invention provides that the inflation time is between 2 and 6 s, preferably 4 s; the holding time between 4 and 12 s, preferably 8 s; and the venting time is between 6 and 14 s, preferably 10 s. These measures cover the most therapeutically suitable parameters.

Another advantageous development of the invention provides that the stimulation insert, with the exception of the connecting means, consists of a thermoplastic polyurethane or a polyvinyl chloride. As a result, the stimulation insert can be produced very easily when using compressed air as the stimulation medium. The individual walls between the adjacent stimulation fields can be produced, for example, by welding two foils that form the upper and lower surfaces; the same applies to the outer walls, which close off the stimulation application with respect to the environment.

A further advantageous development for all conceivable stimulation media provides that the stimulation fields, in particular the air chambers and / or the electrodes, are arranged in a meandering manner within a row. This provides good control of the rolling movement away from the air inlet to the second end of each row. In particular, when using compressed air as the stimulation medium, the rolling movement can be time-controlled very well.

Another advantageous development of the invention provides that the connecting means has elastic textiles, cords, bandages, a Velcro fastener, a zip fastener or a snap fastener. These connecting means are very easy to handle and allow a secure connection between the stimulation insert and the cuff or the orthosis, these connecting means also being very easy to detach, but at the same time ensuring a sufficiently high level of security against unintentional detachment of the connection.

The stimulation insert according to the invention is preferably connected to a cuff made of chloroprene rubber or elastic textiles, to a rubber mat, to a bandage or to an orthosis. As a result, it can be connected in a very simple manner to the joint to be treated or fixed at the desired point on the body, since the stimulation insert is embedded either in the cuff or in the orthosis, each of which has the necessary connecting means for fixing the entire object the desired location.

When using electrical current as the stimulation medium, the cable that connects the electrodes to the microprocessor, in particular the ribbon cable, is preferably arranged in a clipboard that is formed on the cuff or orthosis. As a result, the cable does not interfere with the optics and it is securely guided within the cuff or the orthosis, so that the cable cannot be damaged - even if the cuff or orthosis is subjected to high loads.

An advantageous development of the invention provides that wings are formed in the area of the first ends of the rows, each running horizontally to the left and to the right, the stimulation fields of which are arranged following the second ends of the rows. This provides a stimulation insert with larger and more complex structures, which offers advantages in particular for the back area, since not only a joint is enclosed - in the back area these are the vertebrae of the spine, which are enclosed by the rows in the direction of the heart - but also Additional stimulation of the underlying tissue can be carried out over part of the back or the entire back in the horizontal direction. In the horizontally extending wings - unlike in an embodiment of the rows with meandering stimulation fields - a straight arrangement of the stimulation fields is preferred.

A further advantageous development of the invention provides that the rows have a butterfly shape and the at least one supply line element or further supply line elements is / are arranged at the free ends of the rows that are adjacent to one another. A butterfly shape is understood to mean a shape that connects two devices with rows arranged in a V or U shape with one another in such a way that their free, i.e. second ends remain free, second ends even in the butterfly shape. This makes it possible to carry out more complex treatments of certain parts of the body, all of which have already been mentioned above described advantages of the stimulation insert according to the invention are still present.

Another advantageous development of the invention provides that the stimulation insert has at least one connecting means for connection to an orthosis or a cuff. These devices can be applied particularly well to the part of the body to be treated.

Another advantageous development of the invention provides that the at least one connecting means is designed as a positioning aid, in particular as a sliding coupling, for simple connection to the orthosis or the cuff. As a result, the stimulation insert can be positioned particularly easily in the orthosis or the cuff, and it can be connected to a pump via a hose without any problems.

1 shows a first embodiment of a stimulation insert according to the invention 1 for a knee that works with compressed air as a stimulation medium. The use of stimulation 1 has two rows 2 , 3 of air chambers 2a , 2 B , 3a , 3b , 4th on. Any row 2 , 3 corresponds to one leg of the U-shaped entire stimulation insert 1 . The first ends are in the area of the connection between the two legs 8th and at the free ends of the legs are the second ends 9 of the ranks 2 , 3 arranged. The rows 2 , 3 are arranged to each other so that between them - starting from their first ends 8th - a free space 7th is formed in the application of the stimulation insert 1 - For example, by being received in a cuff or orthosis - a joint can be incorporated; in case of 1 Due to its shape and size, it is a knee joint for which the stimulation is used 1 is trained. For other joints, the proportions have been changed and adapted to the respective joint.

A feed element is located in the area of the connection between the legs 5 - When using compressed air, as in the embodiment of 1 is the case, it is an air inlet, which is also referred to below with the reference symbol “5” - and a sensor connection 6th arranged side by side. The air inlet 5 is connected via a hose to a compressed air source (both not shown), which is the stimulation insert 1 supplied with compressed air. With the sensor connection 6th is a pressure sensor via a hose 23 (please refer 6th - There is a vent valve in another embodiment 25th via an air hose 26th with the sensor connection 6th connected), which is the air pressure in the last air chamber 3b measures. If this exceeds a predetermined value, for example 1.5 bar, the compressed air source is switched off via a suitable device known to the person skilled in the art.

The sensor connection 6th is only in the right, second row 3 formed and with the last air chamber 3b via a drainage channel 13th tied together. The left, first row 2 has no connection to a sensor port 6th on; rather, it forms the last air chamber there 2 B the end of the chain of air chambers 2a , 4th , 2 B .

At the lowest edge of the leg of the stimulation insert 1 is a first air chamber 2a , 3a trained for both the left row 2 as also the right row 3 acts as a single element; For the present exemplary embodiment, this means that the first air chamber 2a the left, first row 2 and the first air chamber 3a the right, second row 3 coincide. This coincidence is not mandatory; the first two air chambers 2a , 3a can also be designed as separate elements. Between air inlet 5 that is inside an inlet chamber 15th is arranged, and first air chamber 2a , 3a is an air outlet 11 educated. To the first air chamber 2a , 3a close one after the other in each row 2 , 3 four air chambers 4th with an air outlet between each 11 in the walls separating them from each other 16 is trained. The last element closes in each row 2 , 3 the last air chamber already mentioned above 2 B , 3b at. The one due to the air vents 11 in the walls 16 specified flow direction of the air flow 17th is meander-shaped and extends - starting from below in the figure - from the respective first end 8th to the second end 9 of each row 2 , 3 . The number of air chambers 4th between the first air chambers 2a , 3a and the last air chambers 2 B , 3b depends on the application, i.e. on which joint it is to be attached, and the size of the individual air chambers 2a , 2 B , 3a , 3b , 4th . The air outlets 11 do not all have to be the same size. For example, it is also possible to do this in the direction of the air flow 17th to train smaller and smaller.

The air outlets 11 are all the same size in the illustrated embodiment - they have a clear width of 3.5 mm. The air outlets 11 are obtained in that an upper and a lower plastic film, each with a thickness of 0.4 mm in the exemplary embodiment, are welded to one another, the weld seam width being 1-2 mm. These values are only exemplary and can vary greatly depending on the application.

Due to the small size of the air outlets 11 opposite the air chambers 2a , 2 B , 3a , 3b , 4th is thus obtained when compressed air flows in via the air inlet 5 a progressive filling of the individual air chambers 2a , 2 B , 3a , 3b , 4th in the order of their meandering arrangement from bottom to top. The use of stimulation 1 is placed around the hinge during use so that the second ends 9 point towards the heart. This creates a pressure on the tissue around the joint that increases from bottom to top and moves towards the heart. This is comparable to lymphatic drainage. This effect is referred to as rolling motion in the following.

In principle, the use of stimulation 1 also in the opposite direction, i.e. with its free, second ends 9 be ordered from the heart pointing the way. With such an arrangement, however, it is then better to use the other stimulation insert constructed according to the invention as described above in the general description 1 to be used with the one at the free, second ends 9 one feed element each 5 is formed and in the region of the first ends 8th a sensor connection 6th is available. Either one or two air outlets can also be formed - an air outlet not being absolutely necessary, since the air can also be passed through the air inlets 5 can escape.

For the in 1 second row shown on the right 3 the air pressure at the sensor connection increases 6th steady and time-delayed compared to the air pressure in the first air chamber 3a at. If at the sensor connection 6th a predefinable value is exceeded, a pump can 21 (please refer 6th ) for filling the stimulation insert 1 serves, turned off. The air in the stimulation insert 1 then escapes through the inlet valve 24 , which is switched to a ventilation mode in which the air escapes into the environment. Alternatively, between the inlet valve 24 and the use of stimulation 1 also a vent valve 25th be arranged via an air hose (see 6th ), which is switched to its venting mode. As an alternative to this before the use of stimulation 1 arranged vent valve 25th or in addition to this can be a vent valve 25th behind the stimulation insert 1 in front of the pressure sensor 23 (please refer 6th ) be arranged; then one or both of the vent valves 25th switched to their venting mode. When the air pressure falls below a predefinable value again, the pump will 21 switched back to its pump mode and filled via the air inlet 5 the first air chamber 3a again. This cycle repeats itself until the application is stopped. A hold mode can be inserted between the end of the pump mode and the start of the suction mode, in which the air pressure in the stimulation application 1 is kept constant. For example, 0.5 bar is taken as the value for switching to hold mode and then subsequently to suction mode. Alternatively, predeterminable fixed inflation times, for example 4 s, holding times, for example 8 s, and venting times, for example 10 s, can also be specified. In both cases, the rolling effect described above is obtained as with lymphatic drainage. Based on 4th Another procedure is described below, such as filling and deflating the stimulation insert 1 can be done.

In another implementation of the invention, not shown, the pump 21 after the presettable value for the air pressure has been reached, they are switched to their suction mode and the air is released from the air chambers 3a , 3b , 4th sucked up until a lower presettable value of the air pressure is reached will. Then the pump 21 switched back to their pumping mode and the cycle repeats itself.

The stimulation insert can for example be made of two layers of a thermoplastic polyurethane that run along the walls 16 between the air chambers 2a , 2 B , 3a , 3b , 4th and the outer walls are welded together. Other materials with suitable manufacturing processes can also be used to create a stimulation insert according to the invention 1 to obtain.

In order to be able to achieve a good application, the stimulation insert is 1 preferably integrated into a cuff or orthosis, as known to those skilled in the art - such a cuff can be made of chloroprene rubber, for example. A releasable and secure connection between the latter and the stimulation insert 1 To achieve this, they are connected to one another, for example, with zippers, press studs or Velcro fasteners. Other materials mentioned above for both the cuff and the connecting means are just as possible.

In 2a is a first embodiment of a stimulation insert according to the invention 1 for the back, with compressed air as a stimulation medium. This is designed for a different purpose - instead of a knee, it is intended for the back. The surrounding joints that are in the free space 7th between the two substantially vertically extending rows 2 , 3 , are vertebrae.

In principle, the first exemplary embodiment for the back is the same as the first exemplary embodiment for a knee, so that parts that are the same or have the same effect are provided with identical reference symbols. In the following, essentially only the differences from the first exemplary embodiment for a knee will be discussed.

The shape and size of the free space 7th is adapted for use around the vertebrae. Also the number, shape and size of those in the two vertical rows 2 , 3 existing air chambers 2a , 2 B , 3a , 3b , 4th is different. The air inlet 5 is in an inlet chamber 15th formed - at the left end in the case shown, but this is by no means limiting - that extend over the entire width of two horizontally extending wings 12th that are in addition to the two rows 2 , 3 available. In the wings 12th are air chambers 4th present that through walls 16 with air outlets 11 are connected to each other. In the leftmost air chamber, the one exhaust chamber 18th is the sensor connection 6th arranged, which is constructed as in the first embodiment and has the same tasks.

The airflow 17th runs here so that the compressed air through the air inlet 5 into the inlet chamber 15th flows. From there it flows through the air outlet 15th in the wall 16 into the first air chamber 2a , 3a , which - as in the first embodiment - common for the first row 2 and the second row 3 is trained. The second air chamber directly above it 4th is also still in both rows 2 , 3 together, then the first row is shared 2 and the second row 3 - as in the first embodiment - on and their air chambers 4th are meandering upwards towards the second ends 9 arranged. To the last air chamber 2 B , 3b the series 2 , 3 a transfer channel closes each outside 14th which leads the compressed air back down into the respective air chamber arranged towards the middle 4th of the two wings 12th . From there, the compressed air flows into each wing 12th each to the outside; being in the left wing 12th in the outlet chamber 18th ends in which the sensor connection 6th is arranged.

Through the wings 12th is in addition to the drainage effect of the rows already known from the first embodiment 2 , 3 an additional rolling movement that is directed outwards, i.e. away from the spine, is generated.

In 2 B is a second embodiment of a stimulation insert according to the invention 1 for the back, shown with compressed air as the stimulation medium. It essentially has two differences from the exemplary embodiment according to FIG 2a on.

The first difference is that the conduit 14th is replaced by two more stimulation fields 4th so that three adjacent columns of stimulation fields 4th there is thus one more column than in the two exemplary embodiments according to 2a .

The second difference is that of stimulation fields 4th free space 7th through a filler piece 33 is filled in with material. When the filler piece 33 made of the same material as the rest of the stimulation insert 1 is made of a plastic film, it can be made in one piece with the rest of the stimulation insert 1 be executed. By filling in the free space 7th with the filler piece 33 receives the entire stimulation input 1 higher mechanical stability. This stability is in the embodiment according to 2 B further increased by the fact that the space between each wing 12th and the subsequent row 2 , 3 by one filler piece each 33 is filled out.

In 3a is an alternative embodiment to 1 for a knee joint, thus a second exemplary embodiment for a knee. There are two main differences from the first Embodiment for a knee according to 1 : To one are stimulation fields 2a , 2 B , 3a , 3b , 4th of the two rows 2 , 3 not arranged in a meander shape, but in a straight line one behind the other and on the other hand are the two rows 2 , 3 not U-shaped or horseshoe-shaped, but have an almost straight upper edge, with the free space 7th for the knee joint is achieved in that the stimulation fields 2a , 2 B , 3a , 3b , 4th of the two rows 2 , 3 in the area of their central, common inlet chamber 15th are made narrower than at the two ends 8th , 9 . This shape allows a different application of the stimulation insert 1 around the knee joint. Here are the two rows 2 , 3 applied from the thigh in such a way that the knee joint is largely enclosed from above.

Instead of the non-meandering arrangement of the stimulation fields 2a , 2 B , 3a , 3b , 4th these can also be meandering - as in the third and fourth exemplary embodiments for a knee 3b and 3c shown - be arranged so that then essentially only one difference due to the straight shape compared to the U-shape of the 1 consists. In terms of the mode of operation, this embodiment is otherwise the same as that of the previous embodiments, so that it does not have to be discussed in more detail here.

In 3b a third embodiment example is shown for a knee. Here is the knee joint 35 - unlike in the other figures relating to a knee - shown schematically. The main difference to the second embodiment according to 3a exists - in addition to the above-mentioned meander-shaped arrangement of the stimulation fields 4th - in that the stimulation use 1 not straight, but curved - comparable 1 but with less curvature - is formed.

In 3c a fourth embodiment of a knee joint is shown. The main difference to the second embodiment according to 3a exists - in addition to the above-mentioned meander-shaped arrangement of the stimulation fields 4th - in that the air intake 5 and the sensor connection 6th are arranged at one end and not in the middle of the stimulation insert 1 . As a result, this embodiment has only one drainage channel 13th - at the top - on.

In 4a is a first embodiment for an ankle 32 shown. This embodiment differs fundamentally from those of FIG 1 until 3 . In the following, these fundamental differences will be discussed in particular.

In addition to the one stimulation insert 1 is another stimulation application 30th present, which is essentially a mirror image of the one stimulation insert 1 is formed and arranged. The two stimulation inserts 1 , 30th are over a jetty 31 connected with each other. There is an air inlet in the web 5 so that from there compressed air into an inlet chamber 15th flows into each of the two stimulation inserts 1 , 30th extends and the compressed air at the respective first end 8th of each stimulation application 1 , 30th in a first air chamber each 2a flows in. From there, the compressed air flows through air chambers one after the other 4th , which are arranged in a U-shape, with the first leg of the U-shape at the first end 8th of each stimulation application 1 , 30th is only very brief. The compressed air flows through the second end 9 of each stimulation application 1 , 30th one last air chamber each 2 B before they each have a drainage channel 13th to a common outlet chamber 18th flows in the jetty. There is a sensor connection there 6th including an air outlet. Adjacent air chambers 2a , 2 B , 4th are like in the other embodiments by walls 16 separated from each other and through air passages formed therein 11 connected with each other. The sequence of air chambers flowed through one after the other 2a , 4th , 2 B are not meandering as in the exemplary embodiments of 1 and 2a , 2 B , 3b and 3c arranged, but in a straight line as in the embodiment according to 3a ; however, alternatively a meandering arrangement can also be used, as shown in the second exemplary embodiment for an ankle according to FIG 4b - otherwise the same as the in 4a The embodiment shown is - is shown.

The devices according to 4a and 4b be so around the two sides of the ankle 32 of a foot placed that the respective long leg of the U-shape - the leg with the respective second end 9 - extends laterally on the lower leg towards the knee. The respective middle leg of the U-shape runs essentially parallel to the sole of the foot on the side of the foot in the applied state. The respective stimulation insert is located towards the respective short leg of the U-shape 1 , 30th on the instep of the foot; this also applies to the respective short leg. This will look like good 4th recognizable - the ankle 32 is surrounded in an L-shape. In the 4a and 4b the state is shown in which only the first stimulation use 1 around one side of the ankle 32 is laid. The following is the bridge 31 bent under the sole of the foot and then the second stimulation insert 30th on the back of the foot analogous to the first stimulation application 1 on the side of the foot shown around the ankle there (not shown). It will help both sides of the ankle 32 each L-shaped with one stimulation insert each 1 , 30th and the action of the compressed air extends to both sides of the ankle 32 .

This in 4c The illustrated third embodiment for an ankle differs from the two in the 4a and 4b Embodiments shown essentially only in that the web 31 - with an air inlet formed on it 5 and sensor connection 6th - not so between the two parts of the stimulation insert 30th is arranged that it is located under the sole of the foot when it is put on, but rests against the calf (not shown). This exemplary embodiment is particularly suitable for an injury in the area of the lower foot, in particular in the ankle area and the patellar tendon. There is a strong stimulation of blood flow or the removal of tissue fluid, which begins on the toes, extends towards the ankles and continues to the lymphs in the lower leg. This means that various swellings can be reduced more quickly.

In contrast, there is the bridge 31 at the in 4d illustrated embodiment for an ankle in the applied state over the back of the foot (not shown). The bridge 31 is formed here only very thin and short and - in contrast to the embodiments according to the 4a until 4c - the air inlet 5 and the sensor connection 6th are not arranged in this, but at the first end 8th of the in 4d left part of the stimulation insert 30th .

In contrast to the other exemplary embodiments of the 1 until 3 is the flow of compressed air in each individual stimulation insert 30th of the embodiments of 4a until 4d not from the respective center of the stimulation insert 1 , 30th starting in both directions, but from - in 4a pictured above - first end 8th to - in 4a shown below - second end 9 . The flow of compressed air therefore only takes place in one direction and not in opposite directions, as in the exemplary embodiments of FIG 1 until 3 .

In 5 an exemplary embodiment is shown which differs from the previous exemplary embodiments with regard to the stimulation medium used. Instead of the compressed air used there, one after the other through air chambers 2a , 2 B , 3a , 3b , 4th flows, electrical current is used here, which is transmitted to the body via spatially distributed electrodes. However, since the geometrical structure is very similar and the electrodes are like those in 1 shown air chambers 2a , 2 B , 3a , 3b , 4th act as stimulation fields, the same reference numerals are used below for the electrodes as above for the air chambers, namely 2a, 2b, 3a, 3b, 4 1 received; Identical or identically acting parts are provided with identical reference numerals. The form of the stimulation insert 1 is the same as that of the first embodiment shown in FIG 1 , since this is also intended for the knee joint.

Instead of two layers of thermoplastic polyurethane, there is a carrier layer here 19th present on which the electrodes 2a , 2 B , 3a , 3b , 4th are upset. The electrodes 2a , 2 B , 3a , 3b , 4th are among each other with a cable 10 tied together. This cable 10 is with a switching device 22nd , here in the form of a microprocessor, via a control line 27 connected, the current required for the application to the respective intended electrode 2a , 2 B , 3a , 3b , 4th brings. The interface between the control line 27 and the cable 10 is located in the start electrode 15th that the inlet chamber 15th in the embodiments according to 1 and 2 is equivalent to. In particular, two basic principles for generating a result equivalent to the above-mentioned rolling movement are possible by using the individual electrodes 2a , 2 B , 3a , 3b , 4th in a given, moving from the first end 8th to the second end 9 meandering "moving" sequence are supplied with power.

The first concept has a cable 10 on that in the desired order from one electrode 2a , 2 B , 3a , 3b , 4th runs to the next and between two adjacent electrodes 2a , 2 B , 3a , 3b , 4th a suitable circuit, for example with a capacitor that charges and, with a time delay, the subsequent electrode 2a , 2 B , 3a , 3b , 4th Supplies electricity. It will be the same for both ranks 2 , 3 identical start electrode 15th - with which only a single, matching first electrode 2a , 3a for the two rows 2 , 3 present - started. Then the cable splits 10 in one for the first row 2 and the second row 3 on that the electrodes 4th , 2 B , 3b along the from the 1 and 2 known path connects. The circuits between adjacent electrodes 2a , 2 B , 3a , 3b , 4th are not shown. The last electrode 2 B , 3b each row 2 , 3 is not connected to any other part, since the electrical current - unlike the compressed air - does not come out of the stimulation insert in a suitable manner 1 must be conveyed out - the current is automatically transferred to the user's skin.

In the other - not shown - preferred principle is each individual electrode 2a , 2 B , 3a , 3b , 4th connected to a microprocessor, which the desired electrode 2a , 2 B , 3a , 3b , 4th according to a pre-determinable program sequence - which can also be changed during operation if necessary - and thus supplies power to it.

The cable used 10 can in all cases be a ribbon cable, which is preferably in an intermediate layer of the cuff or orthosis - in which the stimulation insert 1 is used - runs. The shape and amplitude of the current used can be varied and adapted to individual needs. The electrodes 2a , 2 B , 3a , 3b , 4th are fed, for example, from a multiplexer circuit. The required voltage can originate from different pulse energy storage concepts, for example from capacitive or inductive discharge, a converter in pulse mode or another principle known to the person skilled in the art. For example, both stimulation via the electrodes can be used 2a , 2 B , 3a , 3b , 4th by means of single pulses as well as by means of an alternating voltage signal, whereby the curve shape can be adjusted to the specific application. An individual adjustment to the skin resistance, the electrode moisture and the cuff pressure can also be made. Since the energy required for the stimulation current used is very low, a portable accumulator can be used as the energy source. This has the advantage that the entire device is mobile and can also be used by the user while on the move while moving.

As a further principle, it is also possible to integrate the electronics directly into the cuff or orthosis to which the stimulation insert is connected via the connecting means - for example, directly into individual electrodes 2a , 2 B , 3a , 3b , 4th . This could also result in a time-delayed stimulation on consecutive electrodes 2a , 2 B , 3a , 3b , 4th be achieved. This can be achieved, for example, with a chain of shift registers and thereby controlled switching transistors. This would cause a stimulation pulse to run along an imaginary line from the electrode 2a , 2 B , 3a , 3b , 4th to electrode 2a , 2 B , 3a , 3b , 4th .

The arrangements of the stimulation fields 2a , 2 B , 3a , 3b , 4th according to the embodiments of 2 until 4th Instead of being operated with compressed air, they can in principle also be converted so that they - like the embodiment of 5 - Can be operated with electricity.

In 6th is a schematic of a stimulation insert 1 in connection with a pump 21 and a switching device 22nd , in particular, this can be designed as a computer, as well as other necessary devices shown.

Due to the schematic representation of the stimulation application 1 and for the sake of clarity is only its first row 2 with the first stimulation field 2a , the last stimulation field 2 B and another stimulation field in between 4th and not the second row either 3 as well as other stimulation fields 4th the end 1 until 4th shown.

The first stimulation field 2a is about its air intake 5 (please refer 1 ) with an inlet valve 24 connected, which in turn via an air hose 26th with the pump 21 connected is. Between the inlet valve 24 and the use of stimulation 1 is a branch of the air hose 26th present, at the end of which a vent valve 25th is arranged. Another vent valve 25th is at the end of a junction in an air tube 26th arranged between the one with the last stimulation field 2 B connected sensor connection 6th (please refer 1 ) and a pressure sensor 23 for measuring the air pressure in the stimulation insert 1 at the sensor connection 6th is trained. Instead of two vent valves 25th it is also possible to have just one vent valve 25th to be provided, with regard to the invention it does not matter which of the two vent valves shown 25th not applicable. The pressure sensor 23 is via a data line 28 with the switching device 22nd connected, which via control lines 27 with the pump 21 , the inlet valve 24 and the two vent valves 25th connected is. The use of stimulation 1 - the in 6th only very schematically through three stimulation fields 2a , 3a , 4th is shown - located in a cuff 29 , by means of which a simple attachment to a body part to be treated is possible.

While the pump mode is active, the pump will 21 via the air hose 26th through the open inlet valve 24 Compressed air into the stimulation insert 1 pumped. Here are the two vent valves 25th in the branches in front of and behind the stimulation insert 1 closed. In the pumping mode it is thus caused that the air chambers 2a , 4th , 2 B one after the other, in the order of their arrangement, are filled. While the pump mode is active, the air pressure at the output of the stimulation insert 1 through one through an air hose 26th with this pressure sensor connected 23 measured. The data about the current air pressure are obtained from the pressure sensor 23 via the data line 28 to the switching device 22nd , for example, it is a computer, passed on. In this switching device 22nd the currently measured air pressure is compared with a predefined, user-adjustable air pressure.

As long as the measured air pressure is below the set air pressure, the switching device sends 22nd via a control line 27 a signal to the pump 21 , continue to put compressed air into the stimulation insert 1 to pump.

If the specified air pressure is reached, the switching device sends 22nd via the control line just mentioned 27 a signal to the pump 21 , whereby this is stopped and no more compressed air into the stimulation insert 1 is pumped. The switching device sends at the same time 22nd via another control line 27 a signal to close the intake valve 24 . The air pressure in the air chambers is then set for a specified time that can be set by the user 2a , 4th , 2 B the use of stimulation 1 held constant, so that one can speak of a hold mode.

After the specified time for carrying out the hold mode has elapsed, the switching device sends 22nd via further control lines 27 a signal to open the exhaust valves 25th which leads to a transition to the venting mode. Due to the overpressure in the stimulation insert 1 compared to the ambient air, to which after opening the exhaust valves 25th there is a connection, the air flows out of the air chambers 2a , 4th , 2 B the use of stimulation 1 the end. This outflow is accelerated by the fact that due to the arrangement of the stimulation insert 1 in the cuff 29 on the use of stimulation 1 a pressure through the cuff 29 is exercised. During this venting mode, the air pressure behind the stimulation insert continues to be applied 1 by the pressure sensor 23 measured and the measured values via the data line 28 to the switching device 22nd sent. There the currently measured value is compared with a set value that can be specified by the user.

After the value falls below this value, the switching device switches 22nd the pump 21 (including other components) back to the pump mode described above.

The exhaust valves are used for this 25th via corresponding signals via control lines 27 closed, the inlet valve 24 is opened via a corresponding signal and the pump 21 is again used to fill the stimulation insert 1 turned on. The sequence described above is then repeated with pump mode, hold mode and venting mode.

The effect already described above as a rolling effect is achieved through this process.

As an alternative to the procedure just described, which is based on the measured values of the air pressure in the stimulation insert 1 Depending on, a sequence can also take place that works strictly according to predetermined times for pump mode, hold mode and suction or venting mode, as has already been done above with regard to the 1 and 2 has been described; For example, inflation time 4 s, holding time 8 s and venting time 10 s. This alternative has the advantage that it can be implemented with less technical effort.

For a person skilled in the art, it goes without saying that the hold mode is skipped when the relevant time is set to zero, so that a transition is made directly from the pump mode to the venting mode. Instead of "passive" ventilation by simply opening the outlet valves 25th “active” venting can also take place, as described above with the word suction mode, in which the pump 21 the air from the stimulation insert 1 sucks.
