The upper spreadingthe layer increases the amount of liquid which by evaporation leaves the dressing andthus the amount of liquid that can be disposed of by the dressing. A bandageaccording to the invention may remain on a wound for a longer time than said knowndressings without having to change or dispose of more fluid at the same timeas the known dressing is intended to remain on a wound.
    According to a first preferred embodiment, the wound pad includes oneliquid-transporting first layer, which is arranged below the lower of thespreading layers in abutment against this. The layers included in the wound pad arepreferably adhesively or mechanically bonded to each other and the layer ofvapor-permeable material is adhesively bonded to the wound pad. Those in the wound padthe constituent layers can instead be bonded to each other by means of heatand_pressure or using ultrasound. This ensures that capillary forcesand hydrating forces within the joint have the intended effect.
    Furthermore, the liquid-retaining and liquid-transporting second layer is constitutedof one or fl of your layers containing a mixture of hydrophilic orhydrolyzed absorbent fibers and superabsorbents in powder form,10152025fi berform or other form. Binding fibers may be involved in itliquid retention and liquid transporting second layer._Thereby cana desired suitable balance between the properties of this layer with respect to transportand retention of liquid is obtained.
    The liquid-retaining and liquid-transporting layer is thereby includeddistribute capillaries of different sizes, the capillaries in contact with the otherthe spreading layer is smaller in size than the capillaries in other areas ofliquid retaining and liquid transporting second layer. Furthermore, the proportionsuperabsorbents in the mixture of absorbent fibers and superabsorbentslarger in an upper part of the liquid transporting and liquid retentionlayer than in a lower part thereof.
    One of the spreading layers or both spreading layers can be integrated inthe liquid retaining and liquid transporting layer.
    In one variant, it may be liquid retention and liquid transporting otherthe layer consists of polymeric foam with or without admixture ofsuperabsorbents.
    The liquid-transporting first layer can advantageously consist of onepolymeric foam.
    The spreading layers can be made of tissue, hydro or nonwoven material orpolymeric foam.
    The meadow-permeable layer is preferably a polymeric film,which has a vapor permeability greater than 2000 g / mz per 24h measured according toASTM D 6701.10152025The wound pad can be coated on its underside with a liquid-permeable layerof adhesive, the adhesive coating on the liquid transporting firstthe layer may be discontinuous and consist of a silicone adhesive coated on oneperforated carrier, which in turn is attached to the underside of the wound pad and itvapor-permeable fi elm in the part thereof which extends circumferentiallyoutside the wound pad.
    BRIEF DESCRIPTION OF DRAWINGSThe invention will now be described with reference to the accompanying drawings, bywhich,Fig. 1 schematically shows a cross section through a wound dressing according to a firstpreferred embodiment of the invention, andfi g. 2 shows a view similar to figure 1 of a special unit according to a secondpreferred embodiment of the invention.
    DESCRIPTION OF EMBODIMENTSFigure 1 shows a first preferred embodiment of a wound dressing 1 according torecovery. The dressing 1 comprises a wound pad 2, which is on its undersidecoated with a layer 4 of skin-friendly adhesive. The term "underside" refers tothe lower side of the wound pad 2 in Figure 1, as when using the dressingwill be closest to a wound.
    It will be appreciated that a dressing depending on where it is to be applied to the body mayplaced so that the underside shown in Figure 1 can, for example, be turned upwards.1015202577 57 77 57 "57 77 57 77The terms "above, below, upper, lower, on top" and the likeposition determinations in the description and the claims relate to the relativethe location of different components in relation to each other when the jointhas the location shown in figur l.
    A layer 8 of vapor permeable material extends on top of the wound pad 2 and icircumference outside the wound pad.
    The layer 4 in the preferred embodiment consists of a carrier in the form of aperforated polyurethane layer coated with silicone adhesive covering the areasbetween the perforations, which layer also extends over the part of the layer 8,which circumferentially extends beyond the wound pad 2. The perforated carrier layeris preferably glued to the wound pad 2 and to the cover layer 8.
    The wound pad 2 includes a liquid-transporting first layer 3, on whichtop a first spreading layer 5 extends. Above this layer is oneliquid retaining and liquid transporting layer 6 provided. Finally havethe wound pad 2 a second spreading layer 7 arranged on the upper side ofliquid retaining and liquid transporting layer 6.
    By spreading layers is meant layers with a thickness of less than 5 mm, preferablyless than 3 mm of absorbent material, capable of dispersingabsorbed liquid in directions perpendicular to the thickness direction.
    As previously mentioned, a cover layer 8 of vapor permeable extendspolymer film on top of the second spreading layer, over the side edges oflayers 3-7 and extends beyond the peripheries of these layers to the same heightthe adhesive layer 4. The polymer film 8 is at least on the underside of the part whichextends beyond the 3-7 peripheries of the absorbent layers coated with10152025adhesive, which as shown in Figure 1 may be an extension or part ofthe adhesive layer 4.
    The adhesive layer 4 has two functions in the present joint 1. Firstlyit shall prevent the wound pad 2 from getting stuck in the wound and secondly it shallensure that the dressing is attached to the skin. In addition, of courseallow the wound pad to absorb fluid from the wound. The adhesive coating 4must therefore be liquid permeable and is therefore throughthe presence of the perforation pattern applied discontinuously.
    Another possibility would be to apply an adhesive coating that isliquid permeable per se or refrain from adhesive coating on the wound padunderside of the wound pad 2 has little tendency to get caught in wounds. However,the underside of the cover layer 8 must always be provided with an adhesive coating,at least in the part which extends circumferentially outside the wound pad.
    It is of course also possible to arrange a layer of e.g.bicomponent fibers or a mesh or perforated film of polymeric materialwith little tendency to get caught in wounds between the wound pad 2 and a wound bed e.g.if the adhesive used to attach the dressing to the skin has a tendencyto get stuck in wounds.
    The adhesive coating 4 may consist of any skin-friendly adhesiveare known for use in wound dressings. However, soft is preferredskin-friendly adhesives, e.g. of polyacrylates or silicone adhesive. A big advantagewith soft adhesives is that they can normally be removed from the skin without harmthis. Particularly preferred is silicone adhesive, which also has the propertythat the adhesion to the skin does not increase significantly with time, which is advantageous,especially in dressings which are intended to remain on a wound for a long time,10152025up to fl your days. Addition-curing RTV (Room TemperatureVulcanizing) silicone system, which after mixing crosslinks and forms aself-adhesive elastomer, are examples of suitable adhesives. Examples ofsuch silicone systems are disclosed in EP 0 300 620 A1.
    Wacker SilGel 612 is a commercially available RTV silicone system fromWacker-Chemie GmbH, Munich, Germany By varyingthe proportions between the two components included in this system can bevary the softness and adhesion level of the elastomer formed. Thissilicone system is particularly suitable for the adhesive coating 4.
    Examples of additional soft silicone elastomers are NuSil MED-6340, NuSilMED3-6300, NuSil MED12-6300 from NuSil Technology, Carpintieria, USAand Dow Corning Corporation, Midland, USA.
    A hot melt adhesive similar to Dispomelt® 70-4647 from National Starch and ChemicalCompany, Bridgewater, NJ, USA can also be used.
    The first layer 3 of liquid-transporting material has the task of as soon as possibleas possible absorb excess fluid from a wound. For this reason, it shouldlie close to the wound bed, which means that the adhesive layer 4 should be thin.
    The layer 3 can advantageously consist of an absorbent foam material, e.g. onepolyurethane foam, see for example US 6,051,747. Also other absorbentmaterials other than foam materials are possible to use, for example fi bermaterialbased on cellulose fibers or other absorbent fibers.
    The first spreading layer 5 is to drain the layer 3 from absorbed liquidand for this purpose has capillaries which are smaller than the capillaries in the layer 3.10152025This causes the liquid flow in the first layer 3 to become substantially verticalwhen the dressing in use has the location shown in Figure 1 and after thatabsorbed liquid reached the top of layer 3. This in turn means the riskso that liquid absorbed laterally in the layer 3 can flow out from the lower edgeof the layer 3 and into the plastic film 8 is reduced, which means that the risk ofthat wound fluid should damage healthy skin decreases correspondingly.
    The first spreading layer 5 also has the task of spreading from the layer 3absorbed fluid laterally. By the capillaries in the thin spreading layer5 largely have a horizontal extent and are smaller than the capillaries inlayer 3, the liquid transport laterally will to a greater extent take place in thislayer than in the first layer 3 of absorbent material.
    The spreading layer 5 is preferably made of fiber-based materialscontaining hydrophilic or hydrophilized fibers, such as tissue ornonwoven fabrics of wood or containing fibrous fibers orcellulose-based fibers, e.g. rayon, or other absorbent fibers, e.g.cotton fibers. In such materials, a large proportion of capillaries have horizontalextent. Other materials may also be considered as spreading layers,eg woven or knitted textile materials. An example of a suitable material forthe spreading layer 5 is Fibrella 2000 from Suominen Corp., Tampere,Finland with a basis weight of 30-50 g / m2. It is also conceivable to use a barrelpolymeric foam materials as spreading layers;The liquid retaining and liquid transporting layer 6 must be highretention ability or retention ability, ie. prevent from the woundabsorbed fluid to be released from the dressing back to the wound bed at the exteriorpressure effect, and partly be able to transport liquid from the firstspreading_sheet to the second spreading layer. By the presence of it10152025first spreading layer 5, a large surface of the layer 6 quickly comes into contact withabsorbed liquid, so that a large part of the layer 6 will be engaged fortransport of absorbed liquid to the top of the layer 6 and thus to itsecond spreading_layer 7. A liquid transport from the first spreading layer5 to the liquid retaining and liquid transporting layer 6 therefore comesto occur shortly after the first spreading layer 5 begins to suck liquid from itunderlying layer 3. The liquid retaining and liquid transportingthe layer 6 in the embodiment shown has smaller capillaries than thatthe liquid-transporting layer 3. Thereby, the suction force of the capillaries inlayer 6 greater than the suction force of the capillaries in layer 3, which causes the layer6 and not the layer 3 will primarily suck liquid from the firstspreading layer 5.
    The liquid retaining and liquid transporting layer 6 consists in itpreferred embodiment of a mixture of fibers and superabsorbents,for example polyacrylates in powder, fiber or other form. The fibers canconsist of hydro- or hydrolyzed absorbent fibers, e.g.viscose fibers, cotton fibers, etc., and binder fibers, e.g. synthetic fibers ofthermoplastic material, e.g. polyester. In such a mixture they standthe absorbent fibers for the liquid transport and the superabsorbents for aincrease in fluid retention under pressure. Through a suitablemixture can provide an optimal balance between the requirements of retention capacity andtransport capacity is achieved. Furthermore, it can retain fluid andthe liquid-transporting layer 6 consists of two or fl your layers of differentmixtures of fibers and superabsorbents. For example, it canliquid retaining and liquid transporting layer be composed of threesuch layers, with the proportion of superabsorbents being greatest in the middle layer.
    The proportion of superabsorbents in the mixture of absorbent fibers andsuperabsorbents are suitably 5-60% by weight.1015202510The liquid retaining and liquid transporting layer 6 may also bebuilt of the same type of material as the lower layer 3 with or withoutadmixture of superabsorbent particles. Also foam materials other thanpolyurethane can be used for layers 3 and 6.
    The second spreading layer 7 absorbs liquid from liquid retention andliquid-transporting layer 6 as soon as liquid is absorbed in this layer 6reaches the top of the liquid retention and liquid transport layer 6. Forto accelerate the transport of liquid to the top of the liquid retention andthe liquid transporting layer 6, the capillaries in this layer may have onesize gradient with decreasing size in the upward directionThe second spreading layer 7 may consist of the same material as the firstspreading layer 5. An example of a suitable material is Fibrella 2000.
    Liquid absorbed in the spreading layer 7 will evaporate throughthe vapor permeable polymer 8. lmen 8. It has been found thatthe rate of evaporation, ie the amount of steam transported through itvapor permeable film, increases with the concentration of liquid inthe area under the film and also when the liquid is in contact with the filmunderside. By arranging the spreading layer 7, the highest is obtainedpossible liquid concentration in the area under the film at the same time as itthe spreading layer contributes to having as large an area as possiblefluid concentration. In order for saturation to be achieved quickly in the spreadinglayer 7, this preferably has very small capillaries and is advantageously thin.1015202511It is pointed out that even if the liquid transport takes place in the manner described above willthe lower layer will not be completely drained of liquid but will offer onemoist environment for the wound bed, which is favorable for healing.
    In order for the desired fluid transport from the wound bed to the other spreadinglayer 7 is to take place, it is important that the various layers in the wound pad are in good contactwith each other and that the vapor permeable layer 8 is in good contact with itsecond spreading layer 7. For this purpose, the layer 3 is suitably attached to itfirst spreading layer 5 through a thin layer of glue, for example oneadhesive coating with a basis weight of 10 g / mz. Layer 6 is aerated on the firstthe spreading layer 5 and / or the second spreading layer 7 and thereby getsgood contact with this / these layers through mechanical bonds. It ispossible to further increase the contact between layers 5 and 6, 6 and 7 or 5.6and 7 by entangling or pinning. It is also possible to ensure goodcontact by means of adhesive, heat and pressure or ultrasound, e.g. about the layer6 would consist of a foam material. The second spreading layer 7 ispreferably attached to the layer 6 and to the film 8 by means of thin adhesive layers.
    A way to obtain good contact between spreading layers 5,7 of fibrous material andthe liquid retaining and liquid transporting layer 6 is to atLaying this layer First, lay a thin layer of the fibers to be laidform the spreading layer 5 or 7, then aerate the various fibers includedin layer 6 and then finish the aeration with a thin layer of fibers whichshould form the spreading layer 7 or 5, after which the different layers 5, 6 and 7is connected to an integrated unit by means of, for example, heat andprint. It is, of course, conceivable to integrate only one in this wayof the spreading layers with the layer 6.1015202512To prevent liquid from leaking from the 3-7 side edges of the layers and draindownwards and possibly back to the wound bed, the film can advantageously be tightly attachedto these edges. Because the film 8 is vapor permeable, it is further allowedevaporation of moisture on the skin in the part of the elm that extends circumferentiallyoutside the edges of layers 3-7 of absorbent material, of course belowprovided that the adhesive coating 4 is vapor permeable also in this part.
    To facilitate the attachment of the polymer film 8 to the layers 3-7, this canby vacuum forming, a three-dimensional shape corresponding to the shape ofthe layers. Such a preform is advantageous even if the film is not adhesiveattached to the edges of layers 3-7.
    Another way to prevent leakage is to weld the edges of the wound pad 2.
    The polymer film 8 may be a film of polyethylene, polyester,polytetra fl uoroethylene or polyurethane, which is microporous or otherwisemade vapor permeable. By vapor-permeable film is meant that the plastic filmlets steam through but not liquid under normal conditions.Water Vapor Transmission Rate (WVTR) atthe polymer film 8 must be greater than 2000 g / mz per 24 hours measured with ASTM D6701. Preferably, the polymer film is a monolithic film, i.e. a filmwhere vapor permeability increases markedly if the film is in contact with liquid.
    An example of such a film is Platilon® 2202 from Epurexs Films GmbH & Co.KG, Bomlitz, Germany.
    The dressing according to the invention is designed to be able to remain under oneperiod of fl your days on a wound without having to change. By the woundthereby undisturbed healing for a long period can be facilitatedthe healing process. A decisive factor for how long a bandage can lastleft on an exuding wound is the dressing's fluid handling capacity. With1015202513fluid handling capacity means the amount of fluid a dressing can absorbfrom a wound before it stops working, ie. can no longer absorb from the wounddischarged wound fluid, which is manifested by leakage.
    The liquid handling capacity is thus partly dependent on the amount of liquid whichcan be stored in the dressing partly by the amount of evaporated liquid. While the amountliquid that can be stored to a maximum is time-independent, the amount is evaporatedfluid is dependent on time and is for dressings that are intended to be used for a long timean important parameter. By arranging a second spreading layer betweenthe liquid retaining and liquid transporting layer and the polymer filmit is achieved that evaporation becomes maximum over a large area as soon as liquidabsorbed in the liquid retention and liquid transporting layer reachestop of this. Furthermore, the capillary force is so great in the spreading layercapillaries that the rate of fluid transport in fluid retention andthe liquid-transporting layer 6 is increased when liquid is absorbed in this layercomes into contact with the capillaries in the second spreading layer 7.
    All in all, this means that a wet surface appears during the film 7 earlierthan if the film were to be applied directly to liquid retention andthe liquid-transporting layer without intermediate spreading layers. Thusthe present invention means that the vapor permeability ofthe polymer film 8 can be utilized in a better way than before by the timeduring which maximum evaporation significantly increases through the provision of aspreading layer between the polymer film and the liquid retaining andthe liquid transporting layer and thus also the amount of liquid dressingcan handle for a certain period of time. For dressings that are designed to sitlong on a wound, the evaporation parameter is of great importance.
    Furthermore, the first spreading layer 5 causes the lower layer 3quickly drained so that absorbed liquid quickly reaches layer 6 and can be sucked1015202514up of this layer over its surface. This allows absorbed fluid to reach it quicklyupper spreading layer.Figure 2 shows a dressing 1 'according to a second preferred embodiment ofthe invention. Components of the joint l 'corresponding to the samecomponents in the joint 1 according to fi gur 1 have been given the same in figure 2reference numerals with the addition of a prime character. The wound pad 2 'remainsthus of a liquid retaining and liquid transporting layer 6 'which isarranged between two spreading layers 5 'and 7'. Fluid released by a woundwill thus first be absorbed in the spreading layer 5 'and distributedover the surface of this. Because the spreading layer is thin and has smallcapillaries it will be rapidly saturated, with in the spreading layer 5 'absorbed liquid quickly comes into contact with the liquid carrierlayer 6 ', which transports the liquid further to the second spreading layer7 ', from which liquid evaporates through the vapor permeable filmof the liquid absorbed in the layer 6 'will be stored in anyexisting superabsorbent particles. When the wound pad storage capacityis maximally utilized, ie. when absorbent and superabsorbents inlayer 6 'is filled with liquid, the dressing can still work on the amountliquid that can evaporate per unit time is then greater than or equal to the amountfluid, which is released from the wound bed.
    The described embodiments can be modified without the scope ofthe invention is left. For example, the different layers may have different surface sizes, e.g.the upper layers may have a smaller surface size than the lower ones. Furthermore, they can ithe pads of the wound pad have a shape other than or the same shape as itvapor permeable polymer film, e.g. rectangular or square with roundcorner, round, oval, etc .. If the different layers of the wound dressing contain weldablecomponents, they can be brought into close contact with each other by welding with15by means of heat and pressure or by means of ultrasound. The vapor permeabilitythe layer may be a polymer film and nonwoven laminate, preferablya hydrophobic nonwoven. The scope of the invention should therefore only be limitedof the content of the appended claims;
