Description

Technical Field

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

[0002] Wound dressings are known and are generally suitable for treating a variety of 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 promotes wound healing through multiple mechanisms, including removal of excess exudate, reduction of periwound edema, and increased perfusion. Combined with the physical force exerted by negative pressure, which pulls the wound edges together, this can improve wound outcomes.

[0004] Wound dressings typically include an adhesive skin contact layer for detachably adhering the dressing to the skin surface. Traditionally, the adhesive skin contact layer includes a plurality of perforations (i.e., through-holes in the adhesive skin contact layer) that allow fluids (e.g., wound exudate) to flow through the layer, but prevent tissue from growing into other materials contained in the wound dressing. Typically, the diameter of the perforations does not exceed 1.2 mm to promote adhesion of the skin contact layer to the skin surface and provide the skin contact layer with sufficient breathability, i.e., allowing 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 perforations tend to close, or at least decrease in diameter, due to the silicone adhesive entering and thus blocking the perforations. Although 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, thereby hindering 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 such cases, the skin contact layer may only weakly adhere to the skin surface, such that movement of the patient while the wound dressing is adhered may cause the wound dressing to partially or completely detach from the patient, which adversely affects the ability of the dressing to transmit negative pressure to the wound site.

[0005] Conventional techniques for forming perforations in adhesive layers involve the use of a hot needle process. However, this disadvantageously results in the formation of "waste" around the perforations (i.e., the material intended to be removed to form the perforations is not completely severed from the bulk of the material, thereby partially obstructing the perforations and resulting in a non-planar surface for the skin-contacting layer). To overcome this, ultrasound can be used to create the perforations. However, this method disadvantageously results in the formation of donut-like / volcano-like structures around the perforations.

[0006] Portable systems have been developed that include mechanisms for managing exudate generated by a wound by collecting the exudate within a wound dressing (typically in an absorbent material) and evaporating it through / across the dressing. Such systems mean that a separate collection canister may not be a necessary part of the system. The advantage of not requiring a canister is that the device is smaller and more portable. A disadvantage of such devices 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 eventually cause it to fail and require replacement. The treatment provided by such systems may also be suboptimal, 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, liquid barrier layers do 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. Gelling fibres form a gel when in contact with exudate. However, upon gelling, many wound contact layers weaken and, in some cases, partially separate from the other layers comprised in 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 aims to strike a balance between providing a sufficient amount of gelling fibres and preventing the wound contact layer from separating when wetted by exudate.

[0008] However, known wound contact layers do not adequately achieve this balance and when the wound contact layer becomes 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 therapy, air and wound exudate are removed from the wound site. Wound exudate must be collected away from the wound site. Some known negative pressure therapy systems include a waste tank connected to a pump unit for collecting and storing wound exudate. However, the use of a tank can make the treatment system itself bulky and expensive to manufacture. In addition, replacing the tank or the container in the tank 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 in an attempt to eliminate the need for a canister and pump system. However, such wound dressings often fail to adequately meet the two requirements of an absorbent layer in a wound dressing, namely, that the absorbent layer have a high absorbent capacity and remain flexible (i.e., do not stiffen) while absorbing wound exudate that subsequently dries.

[0011] Known absorbent layers with relatively low absorbency can cause wound exudate to collect at the wound site. This can be uncomfortable and unhygienic for both the patient and the healthcare professional changing the wound dressing. Furthermore, prolonged contact with excess wound exudate can lead to maceration of the wound and / or surrounding skin.

[0012] Furthermore, as wound exudate is absorbed and subsequently dries, known absorbent layers typically become relatively stiff. This causes the fabric of the absorbent layer to "bow," which disadvantageously provides a tunneling effect for air transfer and causes air to leak from the wound dressing, thereby adversely affecting the negative pressure delivered to the wound site.

[0013] Conventional negative pressure wound dressings typically include relatively rigid dressings and incorporating components, which adversely impacts the system's practicality and provides a relatively rigid wound dressing that is detrimental to user comfort. Furthermore, these components require separate manufacturing steps to incorporate them into the wound dressing, thereby increasing manufacturing time and cost.

[0014] The purpose of such components is to attempt to increase the integrity of the wound dressing, preventing or at least reducing separation of one or more layers contained therein. However, the advantages of such components are often outweighed by the disadvantages associated with additional manufacturing steps, complex processing, and increased rigidity of the final wound dressing. Furthermore, rigid dressings and bonding components often adversely affect the wicking or movement of wound exudate through the wound dressing away from the wound site. Furthermore, existing negative pressure wound dressing systems do not utilize absorbent materials and additional wound dressing components arranged to maximize wound exudate management within the dressing.

[0015] It is known to provide a wound dressing comprising a wound contact layer, a transmission layer, and an absorbent layer arranged such that the transmission layer overlies the wound contact layer and the absorbent layer overlies the transmission layer. This arrangement is disclosed in US Pat. No. 10,507,141. However, this arrangement does not provide significant absorptive capacity. This means that this arrangement suffers from unwanted collection of wound exudate at the wound site. This can improve the hygiene of the wound dressing and the wound site, which in turn increases user comfort.

[0016] It is an object of embodiments of the present invention to at least partially overcome or alleviate 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, a wound dressing comprising an adhesive skin contact layer is provided. The weight of the adhesive skin contact layer can range from 40 grams per square meter (gsm) to 250 gsm. The adhesive skin contact layer can be a perforated mesh. The adhesive skin contact layer can include perforations. The diameter of each perforation can range from 1.25 mm to 5.00 mm.

[0018] The wound dressing may 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 releasably adhere the dressing to a 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 arranged between the backing layer and the adhesive skin contact layer, wherein the adhesive skin contact layer is configured to detachably adhere the dressing to a skin surface, wherein the backing layer comprises 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, further wherein the adhesive skin contact layer is a perforated mesh comprising perforations, each perforation having a diameter in the range of 1.25 mm to 5.00 mm.

[0020] The adhesive skin contact layer includes perforations, each having a diameter ranging from 1.25 mm to 5.00 mm. Advantageously, this means that the perforations have a sufficient diameter to provide breathability to the wound dressing even if the diameter of some perforations decreases after formation. In this way, the adhesive skin contact layer maintains an environment optimal for wound healing.

[0021] Surprisingly, it was found that relatively larger perforations, compared to perforations with a diameter of 1.20 mm known in the prior art, did not adversely affect adhesion to the skin surface. Advantageously, therefore, the present invention functions without loss, or at least significant loss, of the wound dressing's adhesion to the skin surface and thus reliably transmits negative pressure to the wound site.

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

[0023] The perforations comprise 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 a wound, the adhesive skin contact layer prevents, or at least substantially prevents, tissue ingrowth into the other materials of the wound dressing.

[0024] Beneficially, the adhesive skin contact layer helps 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 arranged between the backing layer and the adhesive skin contact layer. Advantageously, this means that the wound exudate is absorbed by the absorbent structure before it contacts the backing layer.

[0141] The thickness of the adhesive skin contact layer may 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 can 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 punching, hot needle processing, laser ablation processing or ultrasonic processing. In particular, the perforations can be formed by mechanical punching. Advantageously, mechanical punching prevents or at least significantly reduces the formation of donut-shaped or volcano-shaped structures around the perforations after the perforations are formed. The perforations can be formed by mechanical punching of an adhesive layer, the adhesive layer including a release liner covering at least one surface of the adhesive layer. After the adhesive layer is mechanically punched, the release liner can be removed from at least one surface of the adhesive layer to remove any "waste" remaining after the mechanical punching.

[0146] The perforations may be formed by punching, a hot needle process or an ultrasonic process.

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

[0148] The adhesive skin contact layer may be of any shape, such as circular, oval, triangular, square, rectangular, hexagonal, octagonal or any irregular shape, such as a trapezoid.

[0149] The adhesive skin contact layer may include a window. Thus, the adhesive skin contact layer may be an adhesive skin contact boundary layer having a perimeter shape. The window may be centrally located relative to the perimeter of the adhesive skin contact layer. The boundary layer may include an outer perimeter defining the outer shape of the boundary, such as a square, rectangle, or circle. The boundary layer may include an inner perimeter defining the shape of the window. The window may have the same or a similar shape as the outer perimeter of the boundary layer. In use, the wound dressing may be adhered to the skin surface such that the wound site is located within the window. In this way, the adhesive skin contact layer does not directly contact the wound site, but rather partially or completely surrounds the wound site. Therefore, the adhesive skin contact layer may only contact intact periwound skin. Advantageously, this means that the wound dressing does not directly adhere to the wound site, so that removal of 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 to the periwound, such that the wound site is located within the window. Thus, when the wound dressing is applied to the patient's skin, the patient's wound is in contact with, or fluidically communicated with, the wound contact layer, for example, and preferably, when the wound dressing is applied to the patient's skin.

[0150] In embodiments including rectangular windows, a greater overlap of the absorbent structure (i.e., a structure that may include a wound contact layer, a transmission layer, and / or a superabsorbent layer) and the adhesive skin contact layer may be provided. Increased overlap may occur at, or toward / adjacent to, respective corner portions of the adhesive skin contact layer and the absorbent structure. Advantageously, the greater overlap allows for a greater surface area of adhesion between the adhesive skin contact layer and the absorbent structure, thereby providing greater structural integrity to the wound dressing. Greater structural integrity means that the absorbent structure maintains its position within the wound dressing, while reducing the likelihood of the absorbent structure shifting / detaching from its position within the wound dressing during use, particularly when the wound dressing is wet with exudate or other fluids.

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

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

[0159] The perforations may be cutouts / notches (i.e., elongated perforations) formed in the adhesive skin contact layer. The adhesive skin contact layer may have a circular shape, and the cutouts may have at least a partially circular or arcuate shape. The cutouts may define at least a portion of a plurality of concentric circles. The cutouts may have a shape that extends at least partially parallel to the outer periphery of the adhesive skin contact layer. The adhesive skin contact layer may include one or more connecting portions extending between the cutouts and / or include connecting portions of the adhesive skin contact layer separated by the cutouts.

[0160] The plurality of perforations may be uniformly or substantially uniformly distributed throughout the adhesive skin contact layer. In some embodiments, the perforations may 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 may be concentrated in multiple areas of the adhesive skin contact layer, thereby defining a plurality of perforation clusters. Each cluster may include the same number of perforations. Each cluster may include a different number of perforations. Each cluster may have the same or substantially the same size and / or shape. Each cluster may have different sizes and / or shapes. One or more clusters may have a shape substantially the same as each perforation. The plurality of clusters may have one or more shapes selected from a circle, triangle, square, rectangle, rhombus, pentagon, hexagon, or octagon. The perforations may be uniformly or substantially uniformly distributed within each cluster.

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

[0162] At least a portion of the adhesive skin contact layer may be convex or otherwise unevenly shaped such that the adhesive skin contact layer has an uneven or non-planar profile when viewed from the side.

[0163] The plurality of through-holes may include a plurality of first through-holes and a plurality of second through-holes.

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

[0170] The first plurality of perforations may be arranged in a border portion of the adhesive skin-contact layer. The second plurality of perforations may be arranged in a central portion of the adhesive skin-contact layer. The central portion may be surrounded by a border portion. Each of the first plurality of perforations may have a larger diameter than each of the second plurality of perforations.

[0171] In some embodiments, the plurality of first perforations and the plurality of second perforations may be arranged in different configurations. For example, the plurality of first perforations may be arranged in multiple columns, and the first perforations in adjacent columns may be staggered / offset relative to each other, such that the plurality of first perforations are arranged in a triangular arrangement, and the plurality of second perforations are arranged around each first perforation.

[0172] The present invention according to the first aspect may of course comprise separately any one or more optional or other features of the present invention according to any other aspect.

[0173] According to a second aspect of the present invention, there is provided a method for forming a plurality of perforations in an adhesive skin contact layer of a negative pressure wound dressing, the method comprising:

[0174] a. Provide an adhesive skin contact layer; and

[0175] b. Forming a plurality of perforations in the adhesive skin contact layer by mechanically punching the perforations.

[0176] The weight of the adhesive skin contact layer may be in the range of 40 gsm to 250 gsm.

[0177] The adhesive skin contact layer may be a perforated mesh. The perforated mesh may comprise a plurality of perforations, each perforation having a diameter in the range of 1.25 mm to 5.00 mm.

[0178] The invention according to the second aspect may of course separately include any one or more optional or other features of the invention according to any other aspect. For example, the adhesive skin contact layer may be an adhesive skin contact layer as defined in the first aspect, optionally including any of the optional features listed above, and the wound dressing may be the wound dressing of the first aspect, optionally including any of the optional features listed above.

[0179] According to another broad aspect of the present invention, a wound dressing comprising a wound contact layer is provided. The wound contact layer may be arranged to contact the wound when the wound dressing is adhered to the skin near the wound. The wound contact layer may have a first surface and a second surface. The first surface of the wound contact layer may contact the wound during use. The first surface of the wound contact layer may include warp stitches. The second surface of the wound contact layer may include warp stitches. The wound dressing may be a negative pressure wound dressing. The dressing may include a backing layer. The dressing may include an adhesive skin contact layer. The dressing may include an absorbent structure. The absorbent structure may be arranged between the backing layer and the adhesive skin contact layer. The backing layer may include a coupling member configured to connect the dressing to a source of negative pressure. The second surface may include warp stitches and weft stitches. The first surface may not include any weft stitches.

[0180] In a third aspect of the present invention, a negative pressure wound dressing is provided, comprising 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 detachably adhere the dressing to a 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, which is 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 the second surface comprises warp stitches.

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

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

[0183] Advantageously, the present invention provides a wound dressing having enhanced adhesion / cohesion between the wound contact layer and any other layers of the absorbent structure, such as a transfer layer located between the wound contact layer and the absorbent layer or backing layer. Thus, the present invention provides a wound dressing that exhibits sufficient strength to hold the layers of the wound dressing together when the dressing is wetted by, for example, exudate, and when the dressing is handled, without compromising its absorbent efficacy.

[0184] Therefore, 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 presents sufficient strength between the layers of the absorbent structure to prevent or at least significantly reduce the possibility of separation of the layers of the absorbent structure.

[0185] The second surface may include warp stitches / trimmed weaves and weft stitches / weft knitted weaves.

[0186] Thus, in one embodiment, a negative pressure wound dressing is provided, comprising 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 detachably adhere the dressing to a 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 characterised in that 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.

[0319] The second surface may comprise about 12.5 warp stitches / cm to about 15.0 warp stitches / cm, about 12.5 warp stitches / cm to about 14.5 warp stitches / cm, about 12.5 warp stitches / cm to about 14.0 warp stitches / cm, about 12.5 warp stitches / cm to about 13.5 warp stitches / cm, or about 12.5 warp stitches / cm to about 13.0 warp stitches / cm.

[0320] The second surface may comprise about 13.0 warp stitches / cm to about 15.0 warp stitches / cm, about 13.0 warp stitches / cm to about 14.5 warp stitches / cm, about 13.0 warp stitches / cm to about 14.0 warp stitches / cm, or about 13.0 warp stitches / cm to about 13.5 warp stitches / cm.

[0321] The second surface can comprise from about 13.5 warp stitches / cm to about 15.0 warp stitches / cm, from about 13.5 warp stitches / cm to about 14.5 warp stitches / cm, or from about 13.5 warp stitches / cm to about 14.0 warp stitches / cm.

[0323] The second surface may comprise from about 14.5 warp stitches / cm to about 15.0 warp stitches / cm.

[0324] The first surface may not include any weft stitches.The first surface may only include warp stitches.

[0325] Thus, in one embodiment, a negative pressure wound dressing is provided, comprising 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 detachably adhere the dressing to a 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, the wound contact layer being 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 the second surface comprises warp stitches and weft stitches, and characterised in that the first surface does not comprise any weft stitches.

[0326] Advantageously, this means that the amount of non-gelling fibres (which may include weft stitches) at the wound contact surface is minimised. Consequently, at the wound contact surface, which is in contact with the wound and therefore wound exudate, the ratio of gelling fibres to non-gelling fibres is greater. Consequently, the absorptive capacity of the wound contact layer is increased. In this way, pooling of wound exudate at the wound site is prevented or at least significantly reduced.

[0327] The second surface may comprise less than 15.0 weft stitches / cm, less than 14.5 weft stitches / cm, less than 14.0 weft stitches / cm, less than 13.5 weft stitches / cm, less than 13.0 weft stitches / cm, less than 12.5 weft stitches / cm, less than 12.0 weft stitches / cm, less than 11.5 weft stitches / cm, less than 11.0 weft stitches / cm, less than 10.5 weft stitches / cm, less than 10.0 weft stitches / cm, less than 9.5 weft stitches / cm, less than 9.0 weft stitches / cm, less than 8.5 weft stitches / cm, less than 8.0 weft stitches / cm, less than 7.5 weft stitches / cm, less than 7.0 weft stitches / cm, less than 6.5 weft stitches / cm, less than 6.0 weft stitches / cm, less than 5.5 weft stitches / cm, less than 5.0 weft stitches / cm, less than 4.5 weft stitches / cm, less than 4.0 weft stitches / cm, less than 3.5 weft stitches / cm, less than 3.0 weft stitches / cm, less than 2.5 weft stitches / cm, less than 2.0 weft stitches / cm, less than 1.5 weft stitches / cm, less than 1.0 weft stitches / cm, less than 0.8 weft stitches / cm, less than 0.6 weft stitches / cm, less than 0.5 weft stitches / cm, less than 0.4 weft stitches / cm, less than 0.3 weft stitches / cm, less than 0.2 weft stitches / cm, or less than 0.1 weft stitches / cm.

[0332] The weft stitches typically impart strength to the wound contact layer fabric in the transverse direction. Advantageously, therefore, the second surface comprising weft stitches enhances the strength of the wound contact layer fabric in the transverse direction. This prevents, or at least significantly reduces, the likelihood of the wound contact layer separating when the wound contact layer becomes wetted by exudate.

[0333] The second surface may not include any weft stitches.The second surface may only include warp stitches.

[0334] The wound contact layer may have a peripheral region and a central region. The peripheral region may completely or at least partially surround the central region.

[0398] In embodiments comprising a surface having warp stitches and weft stitches, the weft stitches are located between the warp stitches and are "knotted" to the warp stitches at anchor points. The anchor points may be spaced about 1 mm, about 2 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, or about 10 mm apart.

[0399] The wound contact layer may comprise a plurality of gel-forming fibers / gelling fibers. Gel-forming fibers refer to hygroscopic fibers that become moist, smooth, or gel-like after absorbing wound exudate. Gel-forming fibers may be of a type that maintains its structural and fiber integrity while absorbing exudate, and therefore maintains significant tensile strength, or may be of a type that loses its fiber form and becomes an amorphous or structureless gel. The gel-forming fibers may be sodium carboxymethylcellulose fibers, chemically modified cellulose fibers, alkyl sulfonate-modified cellulose fibers, pectin fibers, alginate fibers, chitosan fibers, hyaluronic acid fibers, or other polysaccharide fibers, or fibers from gums or plants, or combinations or blends of these fibers.

[0400] The wound contact layer may comprise a combination or blend of gelling and non-gelling fibers. The gelling and non-gelling fibers may be any such fibers disclosed herein.

[0409] The wound contact layer may comprise a combination or blend of fibers including fibers formed from sodium carboxymethylcellulose in an amount greater than or equal to about 50% of the total mass of the fiber combination or blend, and cellulose fibers in an amount less than or equal to about 50% of the total mass of the fiber combination or blend.

[0410] Combinations or blends of gelling and non-gelling fibers can be blended into nonwoven fabrics. The nonwoven fabrics can be stitch-bonded as described herein. In embodiments comprising sodium carboxymethylcellulose fibers, the degree of substitution of the fibers can be from about 0.05 carboxymethyl groups per glucose unit to about 0.50 carboxymethyl groups per glucose unit, from about 0.10 carboxymethyl groups per glucose unit to about 0.45 carboxymethyl groups per glucose unit, from about 0.15 carboxymethyl groups per glucose unit to about 0.40 carboxymethyl groups per glucose unit, from about 0.20 carboxymethyl groups per glucose unit to about 0.35 carboxymethyl groups per glucose unit, from about 0.25 carboxymethyl groups per glucose unit to about 0.35 carboxymethyl groups per glucose unit, or from about 0.30 carboxymethyl groups per glucose unit.

[0411] Advantageously, this means that the sodium carboxymethylcellulose fibers have relatively high gelling properties, i.e., greater absorbency and retention, than fibers typically included in prior art wound contact layers. Consequently, the wound contact layer is able to absorb and retain greater amounts of wound exudate than a wound contact layer that does not include sodium carboxymethylcellulose fibers, without adversely affecting its adhesion / attachment to other layers in the absorbent structure. Pooling of wound exudate at the wound site is thereby prevented or at least significantly reduced.

[0412] Furthermore, in some embodiments, the first surface includes no or a relatively small number of weft stitches. In such embodiments, advantageously, due to the low number or absence of weft stitches, the gel-forming fibers are in greater contact with the wound than with prior art wound dressings that include a wound contact layer having warp stitches and weft stitches on the wound contact surface. Consequently, the wound contact layer of the present invention absorbs significantly greater amounts of wound exudate than prior art wound contact layers.

[0413] In embodiments comprising sodium carboxymethylcellulose fiber, the degree of substitution of the fiber can be about 0.05 carboxymethyl groups per glucose unit, about 0.10 carboxymethyl groups per glucose unit, about 0.15 carboxymethyl groups per glucose unit, about 0.20 carboxymethyl groups per glucose unit, about 0.25 carboxymethyl groups per glucose unit, about 0.30 carboxymethyl groups per glucose unit, about 0.35 carboxymethyl groups per glucose unit, about 0.40 carboxymethyl groups per glucose unit, about 0.45 carboxymethyl groups per glucose unit, or about 0.50 carboxymethyl groups per glucose unit.

[0414] In embodiments comprising sodium carboxymethylcellulose fiber, the degree of substitution of the fiber can be at least about 0.05 carboxymethyl groups per glucose unit, at least about 0.10 carboxymethyl groups per glucose unit, at least about 0.15 carboxymethyl groups per glucose unit, at least about 0.20 carboxymethyl groups per glucose unit, at least about 0.25 carboxymethyl groups per glucose unit, at least about 0.30 carboxymethyl groups per glucose unit, at least about 0.35 carboxymethyl groups per glucose unit, at least about 0.40 carboxymethyl groups per glucose unit, at least about 0.45 per glucose unit, or at least about 0.50 carboxymethyl groups per glucose unit.

[0415] In embodiments comprising sodium carboxymethylcellulose fiber, the degree of substitution of the fiber can be no more than about 0.05 carboxymethyl groups per glucose unit, no more than about 0.10 carboxymethyl groups per glucose unit, no more than about 0.15 carboxymethyl groups per glucose unit, no more than about 0.20 carboxymethyl groups per glucose unit, no more than about 0.25 carboxymethyl groups per glucose unit, no more than about 0.30 carboxymethyl groups per glucose unit, no more than about 0.35 carboxymethyl groups per glucose unit, no more than about 0.40 carboxymethyl groups per glucose unit, no more than about 0.45 per glucose unit, or no more than about 0.50 carboxymethyl groups per glucose unit.

[0416] In embodiments comprising sodium carboxymethylcellulose fiber, the degree of substitution of the fiber can be from about 0.05 carboxymethyl groups per glucose unit to about 0.50 carboxymethyl groups per glucose unit, ...
