Description

Technical Field

[0001] The present invention relates to a wound dressing. In particular, the present invention relates to a negative pressure wound dressing. Background Art

[0002] Wound dressings are known and are generally suitable for treating various wounds, including chronic and acute wound types such as infected wounds, venous ulcers, diabetic ulcers, burns, and surgical wounds.

[0003] Negative pressure has been used to treat a range of chronic and acute wounds. Negative pressure can promote wound healing through a variety of mechanisms, including clearing excess exudate, reducing edema around the wound, and increasing perfusion. Combined with the physical force exerted by the negative pressure to pull the wound edges together, this can improve wound outcomes.

[0004] Wound dressings typically include an adhesive skin contact layer for separably adhering the dressing to the skin surface. Conventionally, the adhesive skin contact layer includes a plurality of perforations (i.e., through-holes in the adhesive skin contact layer) that allow fluids (such as wound exudate) to flow through the layer but prevent tissue from growing into other materials contained within the wound dressing. Typically, the diameter of the perforations does not exceed 1.2 mm to facilitate adhesion of the skin contact layer to the skin surface and to provide sufficient breathability to the skin contact layer, i.e., to allow water vapor and gases to pass through the layer. Typically, the skin contact layer includes a silicone / silicone resin / polysiloxane / organic silicon (silicone) adhesive. Unfortunately, after the perforations are formed, some of the perforations tend to close, or at least decrease in diameter, as the silicone adhesive enters and thus blocks the perforations. While this can increase the adhesion of the layer to the skin surface, it adversely affects the breathability of the skin contact layer, causing body fluids to accumulate at and near the skin or wound site, and thus, preventing the formation of an environment that is optimal for wound healing. Conversely, it is known to increase the size of the perforations in the adhesive skin contact layer to aid breathability. However, this is achieved at the expense of the adhesion of the skin contact layer to the skin surface, in which case the skin contact layer may only weakly adhere to the skin surface, such that movement of the patient during adhesion of the wound dressing may cause the wound dressing to partially or completely detach from the patient, which adversely affects the transfer of negative pressure to the wound site.

[0005] Conventional techniques for forming perforations in the adhesive layer include using a hot needle process. Unfortunately, this results in the formation of "scrap" around the perforations (i.e., the material intended to be removed to form the perforations is not completely disconnected from the material body, and thus, partially obstructs the perforations and results in a non-planar surface of the skin contact layer). To overcome this, ultrasound can be used to generate the perforations. However, this method adversely forms a doughnut-shaped / volcanic structure around the perforations.

[0006] Portable systems have been developed that include means for managing wound exudate by collecting exudate within a wound dressing (typically within an absorbent material) and evaporating it through / across the dressing. Such systems imply that a separate collection can may not be an essential part of the system. The advantage of not requiring a can is that the device is smaller and more portable. The disadvantage of such a device is that if the dressing exceeds its fluid handling capacity, exudate may be drawn out of the absorbent material and into the pump. The presence of exudate in the pump will ultimately cause it to fail and require replacement. The treatment provided by the system may also not be optimal as excess exudate may accumulate or pool at the wound interface. To prevent exudate from contaminating the pump, it is known to provide a barrier layer between the absorbent material and the pump. However, the liquid barrier layer does not improve the ability of the absorbent material to absorb exudate.

[0007] Wound contact layers are known to comprise a mixture of gelling and non-gelling fibres. The gelling fibres form a gel upon contact with exudate. However, when forming the gel, many wound contact layers become weak and in some cases partially separate from other layers contained within the absorbent structure. To overcome this, it is known to provide non-gelling fibres as part of the wound contact surface of the wound contact layer. This arrangement is intended to achieve a balance between providing a sufficient amount of gelling fibres and preventing the wound contact layer from separating when the wound contact layer is wetted by exudate.

[0008] However, known wound contact layers do not fully achieve this balance and when the wound contact layer is wetted by exudate, these layers either do not adequately prevent exudate from pooling on the wound contact surface or do not adequately adhere / attach to other layers within the wound dressing.

[0009] During negative pressure treatment, air as well as wound exudate material is removed from the wound site. The wound exudate must be collected from a location remote from the wound site. Some known negative pressure treatment systems include a waste can connected to a pump unit for collecting and storing wound exudate material. However, the use of a can results in the treatment system itself being bulky and expensive to manufacture. In addition, replacing the can or the container within the can in which the wound exudate is collected can be a time-consuming and relatively unhygienic process.

[0010] Negative pressure wound dressings have been produced that include an absorbent layer to absorb wound exudate, attempting to eliminate the need for a can and pump system. However, such wound dressings often do not fully meet two requirements of the absorbent layer in a wound dressing, namely that the absorbent layer has a high absorption capacity and remains flexible (i.e., does not harden) when absorbing subsequently dried wound exudate.

[0011] Known absorbent layers with relatively low absorbency can cause wound exudate to accumulate at the wound site. This is uncomfortable and unhygienic for both the patient and the healthcare professional changing the wound dressing. In addition, there is a risk of maceration of the wound and / or the surrounding skin if there is prolonged contact with excessive wound exudate.

[0012] Furthermore, when the wound exudate is absorbed and subsequently dries, known absorbent layers generally become relatively hard. This causes the fabric of the absorbent layer to "bow", which unfavorably provides a tunneling effect for air transfer and causes air leakage from the wound dressing, thus adversely affecting the negative pressure transmitted to the wound site.

[0013] Conventional negative pressure wound dressings typically include a relatively rigid dressing and a bonding component, which adversely affects the usability of the system and provides a relatively rigid wound dressing, which is unfavorable for the comfort of the user. In addition, these components require separate manufacturing steps to incorporate them into the wound dressing, thus increasing the manufacturing time and cost.

[0014] The purpose of such components is to attempt to increase the integrity of the wound dressing to prevent or at least reduce the separation of one or more layers contained therein. However, the advantages of such components generally do not outweigh the disadvantages associated with additional manufacturing steps, complex processing, and the rigidity of the final wound dressing. In addition, the rigid dressing and the bonding component generally have an adverse effect on the wicking or movement of wound exudate through the wound dressing from the wound site. Furthermore, existing negative pressure wound dressing systems do not utilize absorbent materials and additional wound dressing components arranged to maximize the management of wound exudate within the dressing.

[0015] It is known to provide a wound dressing that includes a wound contact layer, a transmission layer, and an absorbent layer, which are arranged such that the transmission layer covers the wound contact layer and the absorbent layer covers the transmission layer. This arrangement is disclosed in US10,507,141. However, this arrangement does not provide significant absorbency. This means that this arrangement suffers from unnecessary pooling of wound exudate at the wound site. In this way, the hygiene of the wound dressing and the wound site can be improved, which in turn increases the comfort of the user.

[0016] An object of embodiments of the present invention is to at least partially overcome or mitigate the above problems and / or to provide an improved wound dressing. Summary of the Invention

[0017] According to a broad aspect of the present invention, there is provided a wound dressing including an adhesive skin contact layer. The weight of the adhesive skin contact layer can be in the range of 40 grams per square meter (gsm) to 250 gsm. The adhesive skin contact layer can be a perforated mesh. The adhesive skin contact layer may include perforations. The diameter of each perforation can be in the range of 1.25 mm to 5.00 mm.

[0018] The wound dressing can be a negative pressure wound dressing. The wound dressing may include a backing layer. The wound dressing may include an absorbent structure. The absorbent structure may be disposed between the backing layer and the adhesive skin contact layer. The adhesive skin contact layer may be configured to separably adhere the dressing to the skin surface. The backing layer may include a coupling member configured to connect the dressing to a negative pressure source.

[0019] According to a first aspect of the present invention, there is provided a negative pressure wound dressing comprising a backing layer, an adhesive skin contact layer, and an absorbent structure disposed between the backing layer and the adhesive skin contact layer, wherein the adhesive skin contact layer is configured to separably adhere the dressing to the skin surface, wherein the backing layer includes a coupling member configured to connect the dressing to a negative pressure source, wherein the weight of the adhesive skin contact layer is in the range of 40 gsm to 250 gsm, and further wherein the adhesive skin contact layer is a perforated mesh including perforations, and the diameter of each perforation is in the range of 1.25 mm to 5.00 mm.

[0020] The adhesive skin contact layer includes perforations, and the diameter of each perforation is in the range of 1.25 mm to 5.00 mm. Advantageously, this means that the perforations have a sufficient diameter to provide breathability to the wound dressing in the case where the diameter of some perforations decreases after the perforations are formed. In this way, the adhesive skin contact layer maintains an environment optimal for wound healing.

[0021] Surprisingly, it has been found that relatively large perforations do not adversely affect the adhesion to the skin surface as compared to perforations having a diameter of 1.20 mm known in the prior art. Thus, it is advantageous that the present invention operates without loss or at least without significant loss of the adhesion of the wound dressing to the skin surface, and thus reliably transfers negative pressure to the wound site.

[0022] Furthermore, it has been found that after the adhesive skin contact layer is manufactured, the perforations having a diameter in the range of 1.25 mm to 5.00 mm do not "close", or at least do not close significantly. In contrast, perforations having a smaller diameter (e.g., 1.20 mm) tend to close after formation, which is due to silicone adhesive entering the perforations and thus blocking the perforations. Thus, the present invention provides an adhesive skin contact layer that ensures sufficient breathability of the wound dressing in use.

[0023] The perforations include through-holes in the adhesive skin contact layer that enable fluid to flow through the layer. Thus, in use, if the adhesive skin contact layer is arranged to cover and contact the wound, the adhesive skin contact layer prevents or at least substantially prevents tissue from growing inwards into other materials of the wound dressing.

[0024] Advantageously, the adhesive skin contact layer helps to maintain the integrity of the wound dressing while also forming an airtight or substantially airtight seal around the absorbent structure to maintain negative pressure at the wound site.

[0025] The absorbent structure may be disposed between the backing layer and the adhesive skin contact layer. Advantageously, this means that wound exudate is absorbed by the absorbent structure before it contacts the backing layer.

[0044] The weight of the adhesive skin contact layer can be from about 180 gsm to about 250 gsm, from about 180 gsm to about 240 gsm, from about 180 gsm to about 230 gsm, from about 180 gsm to about 220 gsm, from about 180 gsm to about 210 gsm, from about 180 gsm to about 200 gsm, or from about 180 gsm to about 190 gsm.

[0045] The weight of the adhesive skin contact layer can be from about 190 gsm to about 250 gsm, from about 190 gsm to about 240 gsm, from about 190 gsm to about 230 gsm, from about 190 gsm to about 220 gsm, from about 190 gsm to about 210 gsm, or from about 190 gsm to about 200 gsm.

[0046] The weight of the adhesive skin contact layer can be from about 200 gsm to about 250 gsm, from about 200 gsm to about 240 gsm, from about 200 gsm to about 230 gsm, from about 200 gsm to about 220 gsm, or from about 200 gsm to about 210 gsm.

[0050] The weight of the adhesive skin contact layer can be from about 240 gsm to about 250 gsm.

[0051] Advantageously, an adhesive skin contact layer having a weight from about 100 gsm to about 250 gsm provides a more ductile gelled structure, and thus, in the case of an air leak, the layer can seal the leak more easily than a layer having a weight below 100 gsm, particularly below 40 gsm. In addition, an adhesive skin contact layer having a weight greater than 250 gsm exhibits processing problems, such as the adhesive may "flow out" from the cut shape, rendering the adhesive skin contact layer unusable.

[0135] The total perforated area can be about 1300 mm 2 、 about 1350 mm 2 、 about 1400 mm 2 、 about 1450 mm 2 、 about 1500 mm 2 、 about 1550 mm 2 、 about 1600 mm 2 、 about 1650 mm 2 、 about 1700 mm 2 、 about 1750 mm 2 、 about 1800 mm 2 、 about 1850 mm 2 、 about 1900 mm 2 、 about 1950 mm 2 、 about 2000 mm 2 、 about 2050 mm 2 、 about 2100 mm 2 、 about 2150 mm 2 、 about 2200 mm 2 、 about 2250 mm 2 、 about 2300 mm 2 、 about 2350 mm 2 、 about 2400 mm 2 、 about 2450 mm 2 、 or about 2500 mm 2 。

[0136] The total perforated area can be about 1300 mm 2 to about 2500 mm 2 、 about 1400 mm 2 to about 2450 mm 2 、 about 1500 mm 2 to about 2400 mm 2 、 about 1600 mm 2 to about 2350 mm 2 、 about 1700 mm 2 to about 2300 mm 2 、 about 1800 mm 2 to about 2250 mm 2 、 about 1900 mm 2 to about 2200 mm 2 、 about 2000 mm 2 to about 2150 mm 2 、 or be about 2100 mm 2 。

[0137] The degree of perforation can be about 5% to about 50%, about 6% to about 45%, about 7% to about 40%, about 8% to about 35%, about 9% to about 30%, about 10% to about 25%, about 10% to about 20%, about 10% to about 15%, or about 12% of the area of the adhesive skin contact layer.

[0138] The degree of perforation can be about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 12%, about 14%, about 16%, about 18%, about 20%, about 22%, about 24%, about 26%, about 28%, about 30%, about 32%, about 34%, about 36%, about 38%, about 40%, about 42%, about 44%, about 46%, about 48%, or about 50% of the area of the adhesive skin contact layer.

[0139] The degree of perforation can be about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 12%, about 14%, about 16%, about 18%, about 20%, about 22%, about 24%, about 26%, about 28%, about 30%, about 32%, about 34%, about 36%, about 38%, about 40%, about 42%, about 44%, about 46%, about 48%, or at least about 50% of the area of the adhesive skin contact layer.

[0140] The degree of perforation can be no more than about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 12%, about 14%, about 16%, about 18%, about 20%, about 22%, about 24%, about 26%, about 28%, about 30%, about 32%, about 34%, about 36%, about 38%, about 40%, about 42%, about 44%, about 46%, about 48%, or no more than about 50% of the area of the adhesive skin contact layer.

[0141] The thickness of the adhesive skin contact layer can be about 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, about 1.0 mm, about 1.1 mm, about 1.2 mm, about 1.3 mm, about 1.4 mm, or about 1.5 mm.

[0142] The thickness of the adhesive skin contact layer can be at least about 0.5 mm, at least about 0.6 mm, at least about 0.7 mm, at least about 0.8 mm, at least about 0.9 mm, at least about 1.0 mm, at least about 1.1 mm, at least about 1.2 mm, at least about 1.3 mm, at least about 1.4 mm, or at least about 1.5 mm.

[0143] The thickness of the adhesive skin contact layer may be no more than about 0.5 mm, no more than about 0.6 mm, no more than about 0.7 mm, no more than about 0.8 mm, no more than about 0.9 mm, no more than about 1.0 mm, no more than about 1.1 mm, no more than about 1.2 mm, no more than about 1.3 mm, no more than about 1.4 mm, or no more than about 1.5 mm.

[0144] The thickness of the adhesive skin contact layer may be from about 0.5 mm to about 1.5 mm, from about 0.6 mm to about 1.4 mm, from about 0.7 mm to about 1.3 mm, from about 0.8 mm to about 1.2 mm, from about 0.9 mm to about 1.1 mm, or about 1.0 mm.

[0145] The perforations can be formed by stamping, hot needle process, laser ablation process or ultrasonic process. In particular, the perforations can be formed by mechanical stamping. Advantageously, mechanical stamping prevents or at least significantly reduces the formation of a doughnut-shaped or volcanic structure around the perforations after the perforations are formed. The perforations can be formed by mechanically stamping the adhesive layer, which includes a release liner covering at least one surface of the adhesive layer. After mechanically stamping the adhesive layer, the release liner can be removed from at least one surface of the adhesive layer to remove any "scrap" remaining after the mechanical stamping.

[0146] The perforations can be formed by stamping, hot needle process or ultrasonic process.

[0147] Each perforation can be the same size, or at least substantially the same size.

[0148] The adhesive skin contact layer can be any shape, such as circular, oval, triangular, square, rectangular, hexagonal, octagonal or any irregular shape, such as an irregular quadrilateral.

[0149] The adhesive skin contact layer may include a window. Thus, the adhesive skin contact layer can be an adhesive skin contact boundary layer having a peripheral shape / outer shape / circumferential shape. The window can be centered / central relative to the perimeter of the adhesive skin contact layer. The boundary layer can include an outer perimeter defining an outer shape of the boundary, the outer shape of the boundary being, for example, square, rectangular, circular. The boundary layer can include an inner perimeter defining the shape of the window. The window can have the same or a similar shape as the outer perimeter of the boundary layer. In use, the wound dressing can be adhered to the skin surface such that the wound site is within the window. Thus, the adhesive skin contact layer does not directly contact the wound site, but rather partially or fully surrounds the wound site. Therefore, the adhesive skin contact layer can only contact the intact skin around the wound. Advantageously, this means that the wound dressing does not directly adhere to the wound site, and thus, removing the wound dressing from the patient does not damage the wound and minimizes patient discomfort. The window allows the adhesive skin contact layer to adhere around the wound such that the wound site is within the window, and thus, when the wound dressing is applied to the patient's skin, allows the patient's wound to contact or be in fluid communication with, for example and preferably, a wound contact layer.

[0150] In embodiments including a rectangular window, a greater overlap of the absorbent structure (i.e., a structure that can include a wound contact layer, a transfer layer, and / or a superabsorbent layer) and the adhesive skin contact layer can be provided. An increased overlap can be present at or towards / adjacent to the respective corner portions of the adhesive skin contact layer and the absorbent structure. Advantageously, the greater overlap allows for a greater adhesive surface area between the adhesive skin contact layer and the absorbent structure, and thus provides greater structural integrity to the wound dressing. The greater structural integrity means that the absorbent structure maintains its position within the wound dressing while reducing the likelihood of the absorbent structure shifting / separating from its position within the wound dressing during use, particularly when used while the wound dressing is wet with exudate or other fluids.

[0151] The area of the window can be from about 900 mm 2 to about 50,000 mm 2 、from about 1600 mm 2 to about 45,000 mm 2 、from about 2500 mm 2 to about 40,000 mm 2 、from about 3600 mm 2 to about 35,000 mm 2 、from about 4900 mm 2 to about 30,000 mm 2 、from about 6400 mm 2 to about 25,000 mm 2 、from about 8100 mm 2 to about 20,000 mm 2, about 10,000 mm 2 to about 15,000 mm 2 , or about 12,500 mm 2 .

[0154] The area of the window may not exceed about 900 mm 2 , not exceeding about 1200 mm 2 , not exceeding about 1600 mm 2 , not exceeding about 2000 mm 2 , not exceeding about 2500 mm 2 , not exceeding about 3000 mm 2 , not exceeding about 3600 mm 2 , not exceeding about 4000 mm 2 , not exceeding about 4400 mm 2, not exceeding about 4900 mm 2 , not exceeding about 5400 mm 2 , not exceeding about 5900 mm 2 , not exceeding about 6400 mm 2 , not exceeding about 6900 mm 2 , not exceeding about 7500 mm 2 , not exceeding about 8100 mm 2 , not exceeding about 8700 mm 2 , not exceeding about 9300 mm 2 , not exceeding about 10,000 mm 2 , not exceeding about 12,500 mm 2 , not exceeding about 15,000 mm 2 , not exceeding about 17,500 mm 2 , not exceeding about 20,000 mm 2 , not exceeding about 22,500 mm 2 , not exceeding about 25,000 mm 2 , not exceeding about 27,500 mm 2 , not exceeding about 30,000 mm 2 , not exceeding about 32,500 mm 2 , not exceeding about 35,000 mm 2 , not exceeding about 37,500 mm 2 , not exceeding about 40,000 mm 2 , not exceeding about 42,500 mm 2 , not exceeding about 45,000 mm 2 , not exceeding about 47,500 mm 2 , or not exceeding about 50,000 mm 2 .

[0155] The perforations may be distributed along a plurality of concentric circles formed around the center point of the skin contact layer. In some embodiments, the concentric circles may be evenly spaced from each other, and / or the perforations in the same concentric circle may be evenly distributed along the circle. The concentric circles may be evenly spaced from each other.

The adhesive skin contact layer can have a circular shape, and the incision can have at least a partially circular shape or an arcuate shape. The incision can define at least a portion of a plurality of concentric circles. The incision can have a shape that extends at least partially in a manner parallel to the outer perimeter of the adhesive skin contact layer. The adhesive skin contact layer can include one or more connecting portions extending between the incisions and / or include connecting portions of the adhesive skin contact layer separated by the incisions.

[0160] The plurality of perforations can be evenly or substantially evenly distributed throughout the adhesive skin contact layer. In some embodiments, the perforations can be unevenly distributed throughout the adhesive skin contact layer such that the perforations are more concentrated in a certain portion of the adhesive skin contact layer than in other portions of the adhesive skin contact layer. The perforations can be concentrated in a plurality of regions of the adhesive skin contact layer, thereby defining a plurality of perforation clusters. Each cluster can include the same number of perforations. Each cluster can include a different number of perforations. Each cluster can have the same or substantially the same size and / or shape. Each cluster can have a different size and / or shape. One or more clusters can have a shape that is substantially the same as each perforation. The plurality of clusters can have one or more shapes selected from a circle, a triangle, a square, a rectangle, a rhombus, a pentagon, a hexagon, or an octagon. The perforations can be evenly or substantially evenly distributed within each cluster.

[0161] The adhesive skin contact layer can include an upper surface and a lower surface. The upper surface and / or the lower surface can be flat or at least substantially flat, for example, due to slightly raised or sunken portions in the adhesive skin contact layer around each perforation, such that when viewed from the side, the adhesive skin contact layer has a uniform, flat profile.

[0162] At least a portion of the adhesive skin contact layer can be raised or otherwise have an uneven shape such that when viewed from the side, the adhesive skin contact layer has a non-uniform or non-planar profile.

[0163] The plurality of perforations can include a plurality of first perforations and a plurality of second perforations.

[0164] The adhesive skin contact layer can include perforations having the same shape but different orientations. For example, the plurality of second perforations can have the same shape as the plurality of first perforations but have a different orientation, such as rotated 20 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, or 180 degrees from the orientation of the plurality of first perforations.

In some embodiments, the plurality of first perforations and the plurality of second perforations may have the same or substantially the same shape. The plurality of first perforations and the plurality of second perforations may have different shapes.

For example, each of the plurality of first perforations may have a larger diameter than each of the plurality of second perforations. In some embodiments, the plurality of first perforations and the plurality of second perforations may each have the same or substantially the same size.

[0180] In a third aspect of the present invention, there is provided a negative pressure wound dressing including a backing layer, an adhesive skin contact layer, and an absorbent structure arranged between the backing layer and the adhesive skin contact layer, wherein the adhesive skin contact layer is configured to separably adhere the dressing to the skin surface, wherein the backing layer includes a coupling member configured to connect the dressing to a negative pressure source, wherein the absorbent structure includes a wound contact layer arranged to contact a wound when the adhesive skin contact layer adheres to the skin near the wound, the wound contact layer having a first surface and a second surface, wherein the first surface of the wound contact layer contacts the wound in use, wherein the first surface includes warp stitches, and the second surface includes warp stitches.

[0181] The warp stitches may comprise any non-gelling fibers.

[0182] Accordingly, the present invention provides a wound contact layer having a reduced amount of non-gelling material (e.g., non-gelling fibers) at the wound contact surface. Advantageously, this facilitates the absorption of wound exudate, thereby preventing the exudate from pooling at the wound site. In this way, an optimal environment for wound healing is maintained at the wound site.

[0183] More advantageously, the present invention provides a wound dressing having a greater adhesion / attachment force between the wound contact layer and any other possible layers of the absorbent structure, such as a transfer layer located between the wound contact layer and the absorbent layer or the backing layer. Accordingly, the present invention provides a wound dressing that exhibits sufficient strength while not compromising its absorption efficacy, such that when the dressing is wetted, for example, by exudate, and when the dressing is handled, the layers of the wound dressing are also held together.

[0184] Accordingly, the wound contact layer of the present invention beneficially prevents or at least significantly reduces the pooling of wound exudate at the wound site, thereby maintaining an optimal environment for wound healing at the wound site and presenting sufficient strength between the layers of the absorbent structure to prevent or at least significantly reduce the likelihood of layer separation of the absorbent structure.

[0185] The second surface may comprise warp stitches / weft knitting and weft stitches / warp knitting.

[0186] Thus, in one embodiment, there is provided a negative pressure wound dressing comprising a backing layer, an adhesive skin contact layer, and an absorbent structure disposed between the backing layer and the adhesive skin contact layer, wherein the adhesive skin contact layer is configured to separably adhere the dressing to the skin surface, wherein the backing layer comprises a coupling member configured to connect the dressing to a negative pressure source, wherein the absorbent structure comprises a wound contact layer arranged to contact the wound when the adhesive skin contact layer is adhered to the skin near the wound, the wound contact layer having a first surface and a second surface, wherein the first surface of the wound contact layer contacts the wound in use, wherein the first surface comprises warp stitches, and wherein the second surface comprises warp stitches and weft stitches.

[0187] The absorbent structure may be disposed between the backing layer and the adhesive skin contact layer.
