    1 A KIT AND THERAPEUTIC PRESSURE ASSEMBLY WITH PATCHES FORAPPLYING PRESSURE TO A LIMB OR OTHER BODY PART T echnícal field of the inVention The present invention relates to a therapeutic pressure assembly and a kitfor making a limb or other body part encircling therapeutic device, for applyingdynamic and/or static pressure to said limb/body part, as Well as to a correspondingmethod for applying a therapeutic compression to a body part. The invention isalso related to patches for use herein, to provide dynamic therapeutic pressure on a limb or other body part.
    Background Compression assemblies or devices, and in particular compressiongarrnents such as compression socks, compression bandages, tubular bandages,pantyhoses, girdles and sleeves, are being used to obtain a static additional sub-bandage pressure for several indications, such as venous insufficiency, oedematreatment, after surgery or treatment of varicose veins, relief in case of injuriessuch as subcutaneous bleeding associated With blunt trauma, muscle sprains, tosupport blood circulation for persons that might have poor circulation, have tostand for a long time, to perform (or recover from) sport activities, or otherphysically demanding activities.
    It is also Well known that flexing the calf - for example When Walking -Will result in a pumping effect that Will enhance the venous retum flow and hencedecrease the degree, or risk, of indications such as leg ulcers and oedema. Thispumping effect may be referred to as a dynamic pressure. In order to improve thispumping effect, one might apply a stiff, or loW stretch, bandage on the calf todynamically increase the pressure peaks resulting in a massaging effect that Willfurther improve the proximal venous retum floW.
    In sports, elastic compression garrnents are today being used in order to:improve recovery, faster Warm up and enhance overall circulation, enhance stability and agility, reduce fatigue and muscle damage and treat injuries such as 2 muscle strains or sprains, or minimize subcutaneous bleeding associated with blunttrauma.
    All indications and problems discussed above are also applicable indifferent settings in veterinary medicine. The variety of indications needs a varietyof different pressures to be applied for optimal function. Depending on indication,e.g. therapy or prevention, and targeted location, the needed pressure to be appliedvaries. However, providing an appropriate pressure, especially for compressiontherapy, is difficult in practice, and there is a great risk that compression is appliedin a non-optimal way. Since the needed pressure varies with the indication andcondition, the optimal pressure distribution is difficult to reach. For example, if anathlete gets a big contusion, one would like to localize a well-defined pressureprofile on the center of that contusion.
    The pressure exerted on a body part by a compression garrnent isdeterrnined by Laplace°s law in terms of the shape of the body part and the hoopforce in the compression garrnent. Typically, the body part has approximatelycircular cross sections, allowing the shape of the body part to be expressed in termsof the circumference, which is easy to measure. It follows from Laplace°s law that,on the one hand, the pressure increases with increasing hoop stress and, on theother hand, decreases with increasing circumference.
    However, increasing the size of a body part - which in itself would causethe pressure to decrease - must also cause the compression garrnent to becomemore stretched, which typically increases the hoop stress. That is, whether theresulting pressure increases, decreases or even stays constant depends on theproperties of the material in the compression garrnent.
    Further, when a patient is walking, the circumference of the legs willnaturally vary due to the flexing of the calves muscles. Furthermore, just standingup will cause an increase in circumference due to gravitational effects.
    It is sometimes a desirable feature that a small dynamic increase incircumference of a body part wearing a compression garrnent should yield asignificant dynamic increase in pressure. That is, the hoop stress should rapidlyincrease with increasing elongation. However, this implies that the stretching of the compression garrnent must be controlled with high precision. If the initial 3 stretching of the garrnent is not enough for the specific circumference, then thestatic pressure can be much too low. If the garrnent is instead stretched just a littletoo much, then the static pressure will be much higher than desired.
    One approach towards achieving both a dynamic increase in pressure and acontrolled static pressure, disclosed in US6338723 and US7329232, is to use agarrnent with a plurality of straps which are secured at a specific elongation,deterrnined by an estimated size of the body part. A set of scales for different bodypart sizes can be provided on the compression garrnent or on a reference card,separate from the compression garrnent. However, the same garrnent and materialis responsible for both the dynamic increase in pressure and the static pressure, andvery precise measurements are required to obtain adequate static and dynamicpressure levels. Furthermore, to simplify the scale, it is necessary to quantify thesize of the body part in discrete groups (such as small, medium and large), so thatthe pressure is only known within a certain pressure range, making the garrnentless controllable.
    Another approach uses multiple components, where different componentsoffer the primary contribution to the dynamic increase in pressure and the staticpressure, respectively. For instance, US20l20238933 discloses a two-layercompression bandage system, where the inner component can be characterized as“short stretch”, which will create a dynamic increase in pressure, and the outerlayer primarily creates the static pressure.
    Similarly, WO20l5007335, by the same applicant, discloses an elasticbandage that exerts a constant static pressure, even when the size of the body partincreases, and which can be combined with a second bandage with “short stretch”,applied at close to zero stretch and optionally fastened in the elastic bandage.
    In practice, however, it is very difficult to properly apply the “short stretch”bandage layer. It is desirable that the bandage material is applied in a stretchedstate, as this makes it easier for the bandage to stay attached to and adapt to theshape of the body part. However, stretching it just a little too much will cause thesecond bandage layer to contribute to or even dominate the static pressure, and if it is not stretched enough, then the dynamic increase in pressure might disappear. 4 Also, use of a completely inelastic bandage material for the second bandagelayer and application of the layer essentially unstretched Would not be a remedy tothis problem. First of all, this Would make it more difficult for the bandage to stayattached to and adapt to the shape of the body part. Further, this results inessentially the same problems as in the first case. A zero stretching force Whenapplying the bandage tends to cause fo lds in the bandage, folds Which Will expandWhen the size of the body part increases, eliminating the desired dynamic increasein pressure. On the other hand, applying the bandage With “almo st” zero stretch isvery difficult even for experienced bandage appliers, and Will again often result inthe second bandage layer contributing to or even dominating the static pressure.
    Thus, there is a need for a compression assembly or device that provides amore efficient and controllable pressure on the limb or other body part Whenapplied, Which is easier to apply on the user°s limb/body part, and/or Which is morecost-efficient to produce. In particular, there is a need for a compression assemblyor device Which yields a dynamic increase in pressure on a body part When its sizechanges, that exerts zero or otherwise controlled static pressure, that adapts to bodyparts of varying size and shape, and/or that does not require measurements When applying the compression garrnent.
    Summary of the invention There is therefore an object of the present invention to provide an assembly,a kit, a patch and a method Which at least partly alleviates the above-discusseddrawbacks, and at least partly addresses the above-identified needs.
    This object is achieved by means of an assembly, a kit, a patch and amethod in accordance With the appended claims.
    According to a first aspect of the present invention, there is provided a kitfor making a limb or other body part encircling therapeutic device, for applyingdynamic and/or static pressure to said limb/body part, comprising: a garrnent or bandage encircling the limb/body part, and preferablyapplying a compression to said limb/body part; and a plurality of patches being releasably attachable to each other and to said garrnent or bandage, Wherein said patches are releasably attachable to each other at 5 overlap areas When arranged at least partly overlapping each other.
    According to another aspect of the invention, there is provided a method forapplying a therapeutic compression to a body part, such as a limb, comprising thesteps: applying a garrnent or bandage encircling the limb/body part, andpreferably providing a compression to said limb/body part; and applying a plurality of patches being releasably attachable to each other andto said garrnent or bandage over said garrnent or bandage in a patchWork, toencircle said limb/body part, Wherein said patches are releasably attachable to eachother at overlap areas When arranged at least partly overlapping each other.
    According to yet another aspect of the invention, there is provided a patchfor providing dynamic therapeutic pressure on a limb or other body part, said patchcomprising a first adherent surface on one side, for attachment to an underlyinggarrnent or bandage, and a second adherent surface on the other side, said secondadherent surface being provided at least around the edges of the patch, forattachment to a first adherent surface of other patches.
    According to still another aspect of the invention, there is provided atherapeutic pressure assembly for encircling a limb or other body part and forapplying dynamic and/or static pressure to said limb/body part, comprising: a garrnent or bandage arranged to encircle said limb/body part andpreferably apply a compression to said limb/body part; and a plurality of patches being detachably attached to said garrnent or bandage,Wherein said patches are arranged partly overlapping each other, and beingdetachably attached to each other at all overlap areas, the patches forrning a secondcontinuous encircling of the limb/body part.
    The present invention is based on the understanding that in order forpressure therapy to Work efficiently, there is a need for a device or assembly Whichis versatile and adaptable, easy to use, and Which provides controllable andpredictable pressure on the limb or other body part to be treated. The presentinvention fi1lf1lls this. The underlying garrnent or bandage may be applied in aneasy and conventional Way, as is per se known, and may, if desired, be arranged to provide a static pressure on the limb/body part. This is then complemented by the 6 layer of patches being arranged over the garrnent/bandage, to provide acontrollable dynamic pressure. The patches are simple to attach and re-attach to thegarrnent/bandage, and it is simple to attach the patches also for inexperiencedusers, users having reduced dexterity, being older or have other limitations ofmobility or the like. The patches are placed in a slightly overlapping manner,thereby forrning a patchWork overlying at least part of the garrnent/bandage.Forrning the second layer With patches in this Way makes it easy to encircle thelimb/body part in any desired Way, and on limbs/body parts having vastly differentsizes, shapes, etc. Since the patches are arranged in an overlapping manner, andsince the patches are not only attached to the underlying garrnent/bandage, butalso, and preferably more strongly, to each other, a continuous second layer isformed by the patches, Which is efficient to provide dynamic pressure to thelimb/body part. It is also simple to address specific needs, and make localadaptations, such as providing low pressure areas, providing access openings, etcin the patch layer.
    Arranging the second layer by patches in this Way is also highlyadvantageous in that it can easily and reliably be arranged free or essentially free ofstatic compression of the limb/body part. Since the patch layer is built up in situover the limb/body part, and since it is built up by means of arranging patches in anoverlapping fashion, no stress or stretch is applied to the patches, and consequentlyno static compression of the limb/body part occurs. Thus, the patch layer onlycontributes to the dynamic pressure, and the static pressure, if so desired, isprovided solely by the garrnent/bandage. This separation makes it possible tocontrol both the dynamic and the static pressure in a very efficient, predictable andsimple Way, and also to control these properties entirely independently of eachother. Thus, the specific properties desired for any specific user and condition cantherefore easily be tailored in a controllable Way, and readjustment of any of theproperties can also be made over time.
    Thus, differently put the present invention is related to the use of doubleadhesive patches of a prescribed elasticity, size and shape in order to create apressure component, With a certain stiffness, for use on e.g. the calves in order to create a massage effect to improve the venous flow back to the heart. 7 The set of patches can be assembled in situ to form a compressionassembly/ device With a controlled static pressure and a dynamic increase inpressure When the size of the body part increases.
    The garrnent/bandage may be of Various per se known types, such asordinary bandages, tube bandages, stockings and other type of compressiongarrnents. The garrnent or bandage may of the type providing a compression of thelimb/body part. However, for some applications and therapeutic treatments, Whereonly a dynamic pressure is required, and no static compression, the garrnent orbandage may be of a type exerting no static compression to the limb/body part.
    In particular, it is preferred to use a garrnent or bandage made of a material inaccordance With WO2015007335, by the same applicant. This material has theadvantage of exerting a very Well defined and predictable static pressure on thelimb/body part, Which remains the same even When the size of the body part varies.Such an elastic bandage/ garrnent preferably has the elastic property that When thesame length of unstretched elastic material is stretched to encircle circular objectWith different circumferences at different yield rates the pressure exerted by theelastic material varies less than 30% over a range of approximately circularcircumferences providing a range of yield rates from kl to k2, Wherein k2/ kl >1.8. Preferably the pressure exerted by the material varies less than 20% over arange of circumferences providing a range of yield rates from kl to k2, andpreferably varies less than 10% Even more preferably, k2/ kl > 1.9, and mostpreferably k2/ kl > 2.0.
    Use of such a garrnents/bandages provides particular advantages incombination With the above-discussed patch layer. Such garrnents/bandagesprovides an essentially constant static pressure, regardless of variations of shapeand size in the limb/body part, and thus, exerts close to no dynamic pressure. Atthe same time, the patches may, as already discussed, provide essentially only adynamic pressure - i.e. the pressure of the patch layer itself may be zero or close tozero When the limb/body part is in a rest position, and then temporarily anddynamically increase When the limb/body part is moved. Thus, the combination ofsuch a garrnent/bandage and the patches allows the dynamic and static pressures to be controlled very precisely and independently. This makes it possible to apply the 8 pressure profile that most eff1ciently treats the indication or indications at hand, asWell as to make individual adjustments to increase patient comfort. This type ofgarrnent/bandage may also be configured or applied to provide close to staticcompression to the limb/body part. Hereby, only a dynamic pressure, provided bythe patch layer, is applied to the limb/body part, Which is advantageous for sometypes of therapeutic treatment.
    The patches are preferably made of a material With short stretch, or non-elastic, and provided With at least one adhesive surface in order to strongly adhereto each other and adhere, at least Weakly, to the underlying material. Each patchpreferably has a shape and size that makes it difficult to accidentally stretch thematerial When applying the patch, and also makes it possible to adapt to body partsof different shapes.
    The therapeutic assembly/ device of the present invention is useable ondifferent types of limbs, and “limb” should in the context of the present inventionbe construed broadly, indicating any extending part of the human or animal body,such as legs, arms and the head. The invention is particularly useful for pressuretherapy on legs. HoWever, the therapeutic assembly/ device of the present inventionis useable also on other body parts, such as on the trunk and the chest.
    All patches preferably have limited dimensions in all directions, comparedto the circumferential dimension of said limb/body part. In particular, it is preferredthat the patches are about the size of a human palm, or the like. For example, eachpatch may have a maximal extension being lower than 30 cm, and preferably lessthan 15 cm, and most preferably less than 10 cm. Further, the patches arepreferably dimensioned such that at least 3 patches are required to encircle thelimb/body part, and preferably at least 5, and most preferably at least 7. Usingpatches of such sizes makes application simple, since the number of patchesnecessary to cover the desired area may hereby be sufficiently small to makemounting simple and quick, and yet suff1ciently large to make it easy to form thepatch layer in concurrence With the shape and size of the limb or other body part tobe covered, and to avoid inadvertent stretching and compression by the patch layer.
    The patches may have various shapes. In one embodiment, at least some of the patches have a tapered end, and preferably having a generally triangular or drop 9 shape. In another embodiment, at least some of the patches have a bone shape,having greater dimensions towards opposite ends, and a narrower waist therebetween. The patch layer may be forrned by use of a single type of patches, allhaving the same size and shape, or by use of two or more different types ofpatches, having e.g. different shapes and/or different sizes.
    The patches are preferably arranged to attach more strongly to each other,at the overlap areas, and less strongly to the garrnent or bandage. This facilitatesmounting, detachment and remounting of the patches, and at the same time makesthe patch layer hold together more strongly.
    Adherence and attachment of the patches may be provided in various ways.In a preferred embodiment, the patches comprise at least one of adhesive (glue)and a hook and loop fabric for attachment to other patches and/or to the garrnent orbandage.
    The patches are preferably made of a substantially inelastic, non-stretchablematerial or low stretchable material. This makes the patch layer relatively inelasticand non-stretchable, which is advantageous for the desired dynamic pressure.However, it is also feasible to use patches which are stretchable.
    The patches preferably comprise a marking around the edges indicating adesignated overlap area. This facilitates mounting, and ensures that the overlap isalways adequately dimensioned, and neither too large nor too small.
    At least one of the patches may further be provided with one or moreopenings. Such opening(s) facilitates migration of air, vapour and liquid throughthe patch layer, and may also be used to create low pressure areas and the like.
    The patches may be provided in a package, e. g. made of plastic film or thelike, and be packed either separately or many together. If two or more patches arepacked together, they may be arranged with the same type of adherent side facingeach other, in order to be easier to separate from each other, or be separated by aseparation layer, such as a plastic film layer, a sheet of paper or the like.
    Preferably, a kit of the above-discussed type comprises a single package,containing a sufficient number of patches to cover body parts of normal size, and/or body parts for which the patches are specif1cally intended. The package may also comprise the bandage/ garrnent, e. g. arranged in a separate compartment of thepackage. However, the bandage/ garrnent may also be provided separately.
    It is also possible to provide the patches in a semi-assembled way, wheretwo or more patches are arranged connected to each other. This may facilitateapplication of the patch layer, and if necessary, some of the semi-attached patchesmay still easily be removed or re-arranged during application. Such patch groups ofsemi-attached patches are of particular advantage if many relatively small patchesare provided.
    These and other features and advantages of the present invention will in thefollowing be further clarified with reference to the embodiments described hereinafter.
    Bríefdescríptíon of the drawíngs For exemplifying purposes, the invention will be described in closer detailin the following with reference to embodiments thereof illustrated in the attacheddrawings, wherein: Figs. la and lb are perspective views of two patches in accordance withone embodiment of the invention, illustrating the attachment of the patches tounderlying garrnent or bandage and to other patches; Figs. 2a and 2b are perspective views of the application of the patchassembly on a limb, and the patch assembly in an applied state, respectively, inaccordance with an embodiment of the present invention; Fig. 3 is a perspective view of a patch assembly similar to the one in Fig. 2,but arranged in a different way, thereby providing a different encircling of the bodyPart; Fig. 4a and 4b are perspective views of a patch assembly similar to the onein Figs. 2 and 3, but arranged in a different way, thereby providing an area havinglower pressure, or being locally uncovered, for accommodation of a locally swollenarea or the like; Figs. 5a-5j are schematic top view illustrations of further embodiments of patch having various shapes; and 11 Fig. 6 is a schematic illustration of an embodiment of a multitude of different patches being used together.
    Detailed description of preferred embodiments In the following detailed description, preferred embodiments of the presentinvention will be described. However, it is to be understood that features of thedifferent embodiments are exchangeable between the embodiments and may becombined in different ways, unless anything else is specifically indicated. Eventhough in the following description, numerous specific details are set forth toprovide a more thorough understanding of the present invention, it will be apparentto one skilled in the art that the present invention may be practiced without thesespecific details. In other instances, well known constructions or functions are notdescribed in detail, so as not to obscure the present invention.
    Figs. la and lb show two patches l of a preferred embodiment of thepresent invention. Figure la shows how the patch l is applied to a body part 2,which is wearing a garrnent or bandage 3.
    The garrnent or bandage 3 may be a conventional, per se knowncompression device, and in particular compression garrnents such as compressionsocks, compression bandages, tubular bandages, pantyhoses, girdles and sleeves,arranged to encircle a part or all of the limb/body part to be treated by exerting apressure towards the limb. The garrnent or bandage 3 is preferably made of anelastic, stretchable material, and preferably a knitted, crochet or woven textilematerial. In particular, it is preferred to use a garrnent or bandage made of amaterial in accordance with WO20l5007335, by the same applicant. This materialhas the advantage of exerting a very well defined and predictable static pressure onthe limb/body part, which remains the same even when the size of the body partvaries. However, other materials and types of garments and bandages may be usedas well to provide the static compression towards the limb/body part.
    The patches l are arranged to provide an outer layer on top of thegarrnent/bandage 3, and encircling all or part of the body limb/body part to betreated. The patches thereby form a second layer continuously encircling the body limb/part, thereby providing a dynamic pressure on the limb/body part. 12 Each patch 1 preferably has a first, inner side or skin side 11, which whenapplied is arranged facing the body part 1 and the underlying garrnent/bandage 2,and an outer side or second side 12, facing outwardly, away from the limb/bodypart.
    The first side 11 of the patches is preferably provided with an adheringlayer that adheres, at least weakly, to the surface of the garrnent/bandage 3 whenthe patch 1 is pressed against it. The patches 1 are placed so that they overlapother, already placed, patches. Further, the second side 12 is preferably alsoprovided with an adherent layer, whereby the patches will adhere to each othereven more strongly at the overlap areas. The attachment between the patches isconsequently arranged to be stronger than the attachment between the patches andthe underlying garrnent or bandage.
    Fig. la is an illustration of a second patch in the process of being attachedto the underlying garrnent/bandage and a previously arranged patch, and Fig. lbshows the result when the patch has been applied.
    The adherent layers may be obtained in various ways. In a preferredembodiment, the first side 11 is provided with hooks and the second side 12 withloops, to forrn a hook and loop type fabric, such as Velcro TM. In anotherembodiment, both sides are provided with adhesive/glue, and preferably anadhesive which makes the patches detachable and re-attachable. It is also preferredthat the adherent layer does not adhere to the skin of a human. In yet anotherembodiment, the first side is provided with hooks and the second side is providedwith glue. In still another embodiment, the first side of the patch is provided with aweakly adherent glue while the second side is provided with glue that does notadhere strongly to the palm of the hand, but does forrn a strong bond with the glueprovided on the first side.
    Figures 2a and 2b show the application of a preferred embodiment of theinvention on a limb 2, here being a human leg. The leg is provided with a garrnent3, here a tubular bandage. For application of the patches, the applicator mayrepeatedly place a patch 1 in the palm of one of his or her hands, with the first sidefacing away from the palm, and press it against the tubular bandage, in an approximately normal direction of the surface of the body part 2. This process 13 continues until the desired section of the body part is covered by overlappingpatches l, as illustrated in Figure 2b.
    In another embodiment, the garrnent/bandage 2 is a bandage orcompression garrnent instead of the tubular bandage. The garrnent/bandagepreferably provides a static pressure to the limb. However, it is also possible to usea garrnent/bandage Which does not provide any pressure, or only a very limitedpressure. Thus, in yet another embodiment, the patches are applied on a non-compression garrnent, such as stockings.
    In order to remove the compression garrnent formed by the patches, itsuff1ces to remove a handful of patches that form a longitudinal path from theproximal side to the distal side and then simply unfold the garrnent formed by thepatches. By reversing the operation, the compression garrnent can be reapplied.
    Figure 3 illustrates an embodiment of the present invention applied to a legWith a distal sWelling, showing hoW the patches l may easily be arranged to adaptto the shape of the body part.
    Figures 4a and 4b illustrate a situation Where local considerations areapplied. In Figure 4a a localized sWelling is being addressed by applying patches l”of smaller sizes over a locally sWelled area, to better conforrn With the localcurvature. When the sWelling has been reduced, the smaller patches can beraäztrrztngczd, or replaced With one or more larger patches, to account for the newvshape of 'the lmdy pztrt.
    In Figure 4b a small area 4 is left uncovered completely, for example forspecial clinical treatment. When treatment has been completed, the area 4 can becovered by one or more patches.
    The patches l are preferably small in comparison With the circumferentialdimension of the limb. Preferably, the patches have a maximal extension beinglower than 30 cm, and preferably less than 15 cm, and most preferably less than l0cm. Further, it is preferred that the patches are dimensioned such that at least 3patches are required to encircle the limb/body part, and preferably at least 5, andmost preferably at least 7. It is further preferred that the patches are about the same size as a human palm. 14 The patches may have various shapes. It is possible to use patches of onlyone shape to cover the limb/body part in a desired way, or to use patches havingtwo or more different shapes. For example, one type of patches has a tapered end,and preferably having a generally triangular or drop shape. Another type of patcheshas a bone shape, having greater dimensions towards opposite ends, and a narrowerwaist there between. Some specific embodiments of the patches will be discussedin more detail in the following, with reference to Figs. 5a-j.
    Figures 5a-j show examples of shapes of the individual patches in preferredembodiments.
    The patch in Figure 5a is a palm sized patch that is elongated along an axisof symmetry which, upon application, will approximately align with the body partslongitudinal direction. The patch has a slightly pointed, tapered shape, whichmakes it easy to adapt the resulting configuration of patches to a body part withtapered shape. This generally drop shaped patch is very versatile and patches ofthis shape may easily be combined to cover vastly different shapes and sizes ofbody limbs/parts.
    Figure 5b shows a patch similar to the one in Fig. 5a, but with straightedges, thereby being shaped as an equilateral triangle. Such a shape is particularlyattractive from a manufacturing point of view, as it can be cut out from a largerpiece of material with minimum wastage, and is still very versatile in application.In a similar embodiment, the comers of the triangle may be slightly rounded inorder to eliminate sharp edges. Another embodiment may use regular n-gons or anyisosceles, or even general, triangles.
    Figures 5c and 5d show two patches that are more elongated than that inFigure 5a. Such shapes are particularly useful when applying the compressionassembly to a long and straight body part, as it reduces the number of patches thatneed to be applied. To reduce the risk of the patches being stretched and appliedtransversally, the patches material of the patches could be such that the patches canbe bent slightly. This allows for the patches to adapt to the large curvature (almostflat) in the longitudinal direction of the body part, but preferably not bend enough to adapt to the small curvature (highly curved) in the transversal direction.
    Figure 5e shows yet another embodiment of a patch, and in thisembodiment the patch is more asymmetric and could be used to create moreVariable patterns and is particularly useful when a local clinical focus is desirable,such as in Figures 4a and 4b.
    Figure 5f depicts a non-convex patch that is not elongated. Such a shape isparticularly useful for body parts that have no clearly defined longitudinaldirection, such as a human head.
    The patches in Figures 5 g and 5h are provided with holes 13, l3°, whichexpose the underlying surface. In the embodiment of Fig. 5g, a plurality of smallholes 13 are provided. A plurality of small holes does not significantly affect thecompression, but does facilitate the transport of liquid, air or vapour through thepatches. In the embodiment of Fig. 5h, a large hole is instead provided. Such alarge opening is useful to avoid covering or applying compression over a certainarea, such as a wound or the eyes or mouth, or for exposing the underlying surfacein order e. g. to facilitate intravenous therapy.
    A compression assembly can contain a mixture of patches, and e.g. patcheswith and without holes. Openings similar to the ones provided by the patches infigures 5 g and 5h can also be created in situ by combining a plurality of smallerpatches without holes so that openings are formed between them. However, abenefit of having the specific patches in Figures 5 g and 5h is that they make it easyto explicitly determine the position of the ho les.
    Many other type of shapes are also feasible, and as yet another example, apatch having a bone shape is illustrated in Fig. 5i, where the dimensions towardsopposite ends are greater than in the central part, thereby forrning a narrower waistbetween the enlarged ends.
    Figure Sj depicts an embodiment of a patch where a section 14 of the patchis visually or tactilely discemible. This marked section 14 is preferably arrangedaround the edge(s) of the patch, and preferably extends inwardly with a certainwidth, preferably in the range 2-15 mm, and most preferably 4-10 mm. Thus, adiscemible band is formed around the perimeter of the patch. Such a discemiblesection along the border of the patch makes it is easy, particularly so for patches of smooth convex shape, to find an outerrnost patch that can easily be removed 16 without affecting any other patch, by clearly visualize how the patches are laid, andwhich patches lies on top of other patches. Another use of such a discemiblesection is to make the user aware of a desired minimum overlap of the patches, inorder to ensure a secure adhesion between the patches. Conversely, the discemiblesection could also be used in order to show that the overlap is excessive. To thisend, it is also feasible to use more than one type of marking, thereby providingdifferent and separately discemible sections. For example, a first section may bearranged immediately following the edge, and a second section may be arrangedconcentrically within the first section. Having more than one discemible sectionmakes it particularly easy to signal both insufficient and excessive overlap.Applying a single discemible section to a patch can also automatically createmultiple discemible sections, such as the three sections lying outside, on or insidean applied discemible section. Thus, a single marked section may e. g. be arrangedaround the edge of the patch, but at a certain distance from the edge itself.
    A patch that is visually or tactilely discemible from the rest can be used tomark a certain position on the body part. Yet another use concems the case whenan individual patch is provided with coating containing a medicament. In thesecases, the entire patch can be provided with visually or tactilely discemible surface,such as having a different color from the rest of the patches.
    The markings may be provided in various forms, e. g. by using a differentcolor in these sections, a different surface roughness, a different type of pattem,etc.
    Markings of this type may easily be combined with any of the above-discussed various possible shapes of the patches, and also with any other desiredshape.
    As already discussed, many of the above-discussed patches have a shapemaking the patches very versatile, so that the same type of patch can be used tocover many different sizes and shapes of various body limbs/parts. However, it isalso possible to use a combination of patches having various shapes. Figure 6shows, as an example, an embodiment of the present invention where patches of varying shapes and sizes are combined. 17 The patches can for example be produced by punching or cutting a materialsheet, provided With hooks on one side and the loops on the other.
    The material sheet can e. g. be a Woven, knitted or non-Woven fabric, or forexample injection molded therrnoplastic material. Further, the material can havevarious elastic properties, including stretching, elasticity and bending flexibility.Even more general, the material can be non-isotropic having different elasticproperties in different directions, both With respect to stretching and bending. Sucha non-isotropy can be aligned With the possible asymmetric shape of the patches,creating various elastic properties of the ensemble of patches as a Whole. HoWever,preferably the patches are non-elastic and non-stretchable, or elastic and stretchableonly to a limited degree.
    Furthermore, the shape, density, length and elastic properties of the hooksand loops Will, besides the stretching elastic properties of the material in the patch,affect the resulting elastic property of the combined assembly of applied patches. Ifanother method of adhesion than hooks and loops is used, one Would obtain yetanother combined elastic property.
    For the patches to adhere or attach to the underlying material, the surface ofthat underlying material and the shape and size of the hooks on the patches is alsoof some relevance. The underlying material, i.e. the material of the garrnent orbandage, is preferably a Woven or knitted fabric, forrning corresponding loops,thereby forrning a textured surface to Which the hooks attach. The hooks can e.g.be made of loops in synthetic monof1lament yam that are cut open to create hooks,or therrnoplastic inj ected moulded hooks in various shapes, Where for example themushroom shape tends to create less damage to the underlying hook material.
    The invention has now been described With reference to specificembodiments. HoWever, several variations of the communication system arefeasible. For example, the patches may take any suitable size and shape, and manyaltematives are feasible in addition to the ones discussed in the foregoing. Further,the underlying garrnent/bandage may be of many different types. Such and otherobvious modif1cations must be considered to be Within the scope of the presentinvention, as it is defined by the appended claims. It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that 18 those skilled in the art Will be able to design many alternative embodimentsWithout departing from the scope of the appended claims. In the claims, anyreference signs placed between parentheses shall not be construed as limiting to theclaim. The Word "comprising" does not exclude the presence of other elements orsteps than those listed in the claim. The Word "a" or "an" preceding an elementdoes not exclude the presence of a plurality of such elements. Further, a single unit may perform the fianctions of several means recited in the claims.
