Description

[0001] Wound cleansing device and wound cleansing product

[0002] TECHNICAL FIELD

[0003] The disclosure relates to a wound cleansing device comprising a number of strand-shaped cleaning elements, at least one of which extends along an optionally curved strand axis, as well as to a wound cleansing product having two opposite and / or opposite sides for performing wound cleansing. Furthermore, the disclosure relates to the use of such wound cleansing devices and products for producing a therapy device.

[0004] BACKGROUND

[0005] Wound cleansing devices of the type described are described, for example, in EP 2365794. In the wound cleansing device described in this document, the strand-like cleaning elements are designed in the form of threads made of synthetic fibers, whereby the threads can also be in the form of monofilament fibers. Each thread extends along a corresponding strand axis. With these wound cleansing devices, the so-called debridement can be carried out particularly gently. Debridement is the process of wound bed preparation in which substances produced by the body itself, i.e., human material such as excessive fluids, fibrin deposits, dead epidermal tissue, such as excessive corneal material or dead horny cells and / or deposits of dead tissue (necrosis), are removed.The known wound cleaning devices are designed as wound cleaning wipes, with the wound cleaning elements, which are implemented as threads, protruding from a carrier layer.

[0006] In the wound cleaning devices known from EP 2365794, the removal of dead epidermal tissue is to be promoted by the fact that the threads are designed with freely projecting ends, wherein the end faces of the freely projecting ends enclose an angle with the strand axis, which produces a razor blade effect in the region of the transition between the end faces of the threads and the lateral surfaces of the threads.

[0007] However, it has been shown that stubbornly adhering substances, such as those found in burns, necroses, or some fibrin coatings, cannot be satisfactorily removed from the wound using known wound cleansing devices. To remedy this deficiency, WO 2020 / 049038 proposes a further development of the known wound cleansing devices, in which the removal of stubbornly adhering substances from the wound is to be promoted by the strand-shaped cleaning elements having a cleaning quotient (R = (E x F) / l, where E denotes the elastic modulus of the material from which the cleaning elements are made, F denotes the mean cross-sectional area of ​​the cleaning elements in a strand cutting plane running perpendicular to the strand axis, and l denotes the effective length of the cleaning elements) of 0.5 N / mm or greater and 1000 N / mm or less.This is intended to give the cleaning elements sufficient rigidity to achieve a balanced compromise between satisfactory cleaning on the one hand and acceptable mechanical stress on the wound during cleaning on the other.

[0008] However, it has been shown that the choice of a cleaning ratio sufficient to remove stubbornly adhering substances within the scope of the invention described in WO 2020 / 049038 can, in some cases, result in unacceptable mechanical stress on the wound during cleaning. This can impair wound healing.

[0009] It has also been shown that - depending on the type of skin covering or wound - the wound cleaning device used can either quickly damage the wound or the cleaning may not be sufficient.

[0010] SHORT DESCRIPTION

[0011] In view of these problems in the prior art, the object of the invention is to provide a means by which satisfactory wound cleansing is possible without complications in wound healing.

[0012] According to the invention, this object is achieved by a further development of the known wound cleaning devices, which is essentially characterized in that the cutting surface of the strand-shaped cleaning elements in one, preferably each, strand cutting plane extending perpendicular to the strand axis has an aspect ratio, that is to say a ratio of greatest extent to extent in a transverse direction running perpendicular thereto, of 5 or more, in particular 10 or more, preferably 15 or more, but 100 or less, in particular 50 or less, preferably 30 or less.

[0013] To illustrate the invention, a cleaning element with a rectangular cut surface in the strand cutting plane is considered by way of example. In such cleaning elements, the aspect ratio refers to the ratio of the length of the diagonal of the rectangle to the dimension of the rectangle in a transverse direction running perpendicular to the diagonal. In the case of a particularly large aspect ratio, this is approximately described by the ratio of the longer side of the rectangle to the shorter side of the rectangle. In a cleaning element with an elliptical cut surface, the aspect ratio refers to the ratio of the major semi-axis to the minor semi-axis. In cleaning devices according to the invention, a razor blade effect, which in wound cleaning devices according to EP 2365794 only occurs in the region of the end faces of the cleaning elements, can be achieved over the entire length of the cleaning element.Thus, each individual wound cleansing element forms a microcurette, which can promote the removal of stubborn substances from the wound over the entire length of the wound cleansing element.

[0014] Unlike the wound cleansing devices described in WO 2020 / 049038, the removal of stubbornly adhering substances is not achieved by increasing the stiffness of the individual cleansing elements, but rather by optimizing the geometric shape of these wound cleansing elements. This prevents impairment of wound healing due to injuries during wound bed preparation while simultaneously achieving satisfactory wound bed cleansing.

[0015] It has been shown that to achieve the described effect, it is sufficient if the aspect ratio of the cleaning elements is 5 or more. However, to maintain sufficient stability of the individual wound cleaning elements, the aspect ratio must be set to a value of 100 or less. Particularly good results are achieved when the aspect ratio is in the range between 10 and 50, especially in the range between 15 and 30.

[0016] In order to ensure sufficient mechanical stability of the individual wound cleaning elements, it has proven expedient if the greatest extent of the strand element in the strand cutting plane is 0.1 mm or more, in particular 0.2 mm or more, particularly preferably 0.4 mm or more. In order to avoid excessively stiff and thus aggressive structures, it has proven expedient if the greatest extent of the strand element in the strand cutting plane is 2 mm or less, in particular 1 mm or less, such as approximately 0.5 mm or less. Accordingly, the extent of the strand elements in the transverse direction in wound cleaning devices according to the invention is expediently 0.01 mm or more, in particular 0.02 mm or more, but 0.2 mm or less, in particular 0.1 mm or less.

[0017] Similar to known wound cleansing devices, wound cleansing devices according to the invention provide a carrier layer, wherein the strand-shaped wound cleansing elements can have an exposed region outside this carrier layer. Sufficient deformability of the cleansing elements is achieved in order to avoid impairing wound healing during wound bed preparation if the length of the exposed region along the strand axis is 2 mm or more, in particular 4 mm or more, optionally 6 mm or more. Excessive deformability of the individual cleansing elements, which is disadvantageous in connection with the removal of stubbornly adhering substances, can be avoided if the length of the exposed region is 20 mm or less, in particular 10 mm or less.

[0018] Within the scope of the invention, it has proven expedient in the sense of utilizing a razor blade effect over the largest possible section of the length of the individual cleaning elements if the exposed area is designed in the shape of a loop, that is to say it exits the carrier layer at an exit point and re-enters the carrier layer at an entry point, wherein the distance between the exit point and the entry point in the sense of forming an effective loop is expediently 2 mm or less, in particular 1 mm or less.

[0019] With a wound cleaning device according to the invention, a flat and thus particularly fast wound cleaning can be achieved if the density of the exposed areas, in particular the number of loop-shaped areas per area of ​​the carrier layer, 10 / cm 2 or more, especially 20 / cm 2or more, although in order to create sufficient absorption capacity between the individual wound cleansing elements, preferably less than 200 wound cleansing elements per cm 2 the surface of the carrier layer. From a production perspective, it has proven advantageous if two, three, or more exposed areas are formed by connected sections of a fiber, in particular a strip-shaped fiber, especially a monofilament fiber. Then, the wound cleansing elements can be woven or knitted into the carrier layer.

[0020] In order to achieve the aspect ratio desired by the invention, wound cleansing elements according to the invention can be designed as strip-shaped fibers with an approximately rectangular or elliptical cross-section, whereby the individual fibers can be designed as synthetic fibers with polyester and / or polyamide components. The fiber can consist of 90 wt.% or more polyester and 10 wt.% or less polyamide, in particular 92 wt.% polyester and 8 wt.% polyamide.

[0021] The carrier layer of wound cleansing devices according to the invention can comprise a woven and / or knitted fabric made of monofilament and / or multifilament fibers. The aspect ratio of the fibers forming the carrier layer can also be approximately 1, while the aspect ratio of the fibers woven or knitted into the carrier layer to form wound cleansing elements can be set to a value between 5 and 50 within the scope of the invention.

[0022] As already mentioned above, at least one cleaning element of wound cleaning devices according to the invention can have an approximately trapezoidal, in particular rectangular, cross-sectional area in a strand cutting plane.

[0023] Within the scope of the invention, it is also intended to equip the wound cleaning device with two, three or more wound cleaning areas, wherein the individual wound cleaning areas have different

[0024] Can have wound cleaning properties. Two wound cleaning areas can be arranged on opposite sides of the carrier layer. A combination of advantages achieved according to the invention with advantages of wound cleaning devices according to EP 2365794 can be achieved if one wound cleaning area has cleaning threads with freely projecting ends, while the other wound cleaning area has loop-shaped cleaning elements, wherein the cleaning threads with freely projecting ends can have an effective length between the carrier layer and the end of the threads facing away from the carrier layer of between 3 and 30 mm and these threads can have between 0.5 and 20 dtex, while the loop-shaped cleaning elements can have an aspect ratio between 5 and 50 with the dimensions described above.

[0025] According to the invention, to achieve the described object, a wound cleansing product is provided which comprises: one or more carrier layers; first fibers for cleansing a wound and / or skin; second fibers for cleansing a wound and / or skin; wherein on a first side of the wound cleansing product, the first fibers are attached to a first of the one or more carrier layers, wherein on a second side of the wound cleansing product, the second fibers are attached to a second of the one or more carrier layers, wherein the first side and the second side are arranged on opposite and / or remote sides of the wound cleansing product.

[0026] The wound cleansing product according to the invention is suitable for debridement and is preferably designed as a two-sided pad. The wound cleansing product according to the invention enables rapid, highly effective, and safe debridement of a wide variety of wounds and / or skin coverings. The wound cleansing product is suitable for cleansing wounds and / or skin (e.g., the skin surrounding the wound).

[0027] The second fibers can have a more abrasive effect than the first fibers. The second fibers can have a highly abrasive effect (e.g., for removing firmly adhered fibrinous wound coverings, calluses, or skin coverings made of dead tissue (necrosis)) and / or the first fibers can have a soft abrasive effect (e.g., for cleaning open wounds). The first fibers are designed to remove debris from the wound and absorb exudate from the wound, as well as to remove scales and keratoses or other skin coverings from the skin surrounding the wound. The second fibers enable easy removal of firmly adhered fibrinous wound coverings or other skin coverings that are more difficult to remove.

[0028] Thus, the wound cleansing product can perform two functions in a single product, which increases the effectiveness of the patient's debridement treatment and conserves the use of resources.

[0029] The first fibers preferably comprise monofilament polyester fibers with a polyacrylate backing. The second fibers preferably comprise polyester-polyamide loops.

[0030] The surface of the first carrier layer to which the first fibers are attached and the surface of the second carrier layer to which the second fibers are attached are oriented in opposite directions. The first carrier layer and the second carrier layer can be a single carrier layer or can be separate carrier layers.

[0031] Preferably, the first carrier layer and the second carrier layer together can form a pocket designed to receive a hand of a user of the wound cleansing product between the two carrier layers, which hand the user inserts into the pocket - in particular to clean the wound and / or skin using the second fibers or to clean the wound and / or skin using the first fibers. The pocket enables a user - after inserting a hand into the pocket - to easily rotate the wound cleansing product around the longitudinal axis of the hand, preferably by approximately 180° (e.g., by guiding a corner of the first and / or second carrier layer with the user's other hand) in order to switch between using the first fibers and using the second fibers on the wound or skin. This allows for quick and flexible, yet hygienic use of the wound cleansing product.In addition, by directly applying the hand in the pocket to the first carrier layer or the second carrier layer (depending on the current orientation of the wound cleansing product), the dosage of manual pressure and the rubbing speed on the wound or skin can be carried out particularly effectively and precisely.

[0032] A wound cleansing kit according to the invention comprises a wound cleansing device according to the invention contained in a sterile package or a wound cleansing product according to the invention contained in a sterile package.

[0033] Within the scope of the invention, the use of a wound cleansing device according to the invention or a wound cleansing product according to the invention for producing a therapy device for the treatment of burns and / or necroses and / or fibrin deposits and / or biofilms and / or bacterial contamination is particularly contemplated. Accordingly, both the wound cleansing device according to the invention and the wound cleansing product according to the invention are designed for use in a method for the treatment of burns and / or necroses and / or fibrin deposits and / or biofilms and / or bacterial contamination.

[0034] It is pointed out that the features explained above can be used individually and in combination with one another for the success sought by the invention (wound bed preparation).

[0035] To the extent that this brief description of the invention describes features that are not listed in the patent claims, these features do not represent essential features in the sense that these features must necessarily be included in the patent claims to describe the invention. However, these features are particularly prominent preferred implementations of the claimed invention, can be combined with any of the patent claims, and can also be combined with each other in any way.

[0040] DETAILED DESCRIPTION

[0041] FIG. i shows a side view of a cross section through an embodiment of the wound cleansing device 10 according to the invention or the wound cleansing product 10 according to the invention.

[0042] The wound cleaning device io has a number (e.g. multitude) of strand-shaped cleaning elements 1, 2, 3, 4, of which at least one extends along an optionally curved strand axis 1A, 2A, 3A, 4A, wherein the cutting surface 1C, 2C, 3C, 4C of this cleaning element in one, preferably each, strand cutting plane 1B, 2B, 3B, 4B extending perpendicular to the strand axis 1A, 2A, 3A, 4A has an aspect ratio, that is to say a ratio of the greatest extent L to the extent W in a transverse direction running perpendicular thereto of 5 or more, in particular 10 or more, preferably 15 or more, but 100 or less, in particular 50 or less, preferably 30 or less. The sectional area or cross-sectional area 1C of the cleaning element i is shown here as a trapezoidal, particularly rectangular, example. The sectional area or cross-sectional area 2C of the cleaning element 2 is shown here as a trilobal example.Cross-sectional area 4C of the cleaning element 4 is shown here as a hollow profile (here with a hollow space). These shapes are particularly effective for cleaning skin or wounds. However, other shapes of the cutting surface or cross-sectional area 1C, 2C, 4C are possible.

[0043] At least one strand-shaped wound cleansing element 1, 2, 3, 4 can have an exposed region outside a carrier layer 5. The exposed region can be loop-shaped, exit from the carrier layer 5 at an exit point 6 located on a first surface 8, and re-enter the carrier layer 5 at an entry point 7 located on the first surface 8, the distance between the exit point 6 and the entry point 7 then being 2 mm or less, in particular 1 mm or less (e.g., 0 mm).

[0044] As shown in FIG. 2 by way of example with reference to the cleaning elements 2 and 3 therein, two (or three or more) exposed regions can be formed by connected sections of a fiber, in particular a strip-shaped fiber, in particular a monofilament fiber. The strip-shaped fiber can comprise a synthetic fiber with polyester and / or polyamide components.

[0045] The carrier layer 5 may comprise a woven and / or knitted fabric made of mono- and / or multifilament fibers.

[0046] As shown in FIG. 2, the fiber forming the two (or three or more) exposed regions may pass through meshes 11 of the carrier layer 5.

[0047] FIG. 3 shows a three-dimensional view of an embodiment of the wound cleansing product 100 according to the invention. The wound cleansing product 100 comprises: one or more carrier layers 5, 22; first fibers 21 for cleansing a wound and / or skin; second fibers 1, 2, 3, 4 for cleansing a wound and / or skin; wherein on a first side of the wound cleansing product 100, the first fibers 21 are attached to a first 22 of the one or more carrier layers, wherein on a second side of the wound cleansing product 100, the second fibers 1, 2, 3, 4 are attached to a second 5 of the one or more carrier layers, wherein the first side and the second side are arranged on opposite and / or remote sides of the wound cleansing product 100. The carrier layers 5, 22 can be a single carrier layer or, as shown here, two interconnected carrier layers 5, 22.

[0048] The second fibers 1, 2, 3, and 4 can have a higher abrasive effect than the first fibers 21. The second fibers 1, 2, 3, and 4 can have a highly abrasive effect (e.g., for removing firmly adherent skin deposits, calluses, or deposits of dead tissue (necrosis)) and / or the first fibers 21 can have a soft abrasive effect (e.g., for cleaning open wounds). Thus, the wound cleansing product can perform two functions in a single product, increasing the effectiveness of patient treatment and conserving resources.

[0049] The first and second fibers may differ in fineness and / or stiffness, whereby the values ​​given herein are particularly effective for the application of the respective fibers.

[0050] The first fibers 21 may be threads with preferably freely projecting ends that protrude from the first carrier layer 22.

[0051] The threads 21 can form a pile in which the effective length of the threads 21 between the first carrier layer 22 and the end of the threads 21 facing away from the first carrier layer 22 is between 3 and 30 mm. At least one of the second fibers 1, 2, 3, 4 can have an exposed region outside the second carrier layer 5, wherein the length of the exposed region along the strand axis of the fiber can be 2 mm or more, in particular 4 mm or more, optionally 6 mm or more, but 20 mm or less, in particular 10 mm or less, optionally 8 mm or less.

[0052] The exposed area can be straight or curved and have a free or cantilevered end.

[0053] The exposed region can alternatively be designed in a loop-shaped manner and exit from the second carrier layer 5 at an exit point and re-enter the second carrier layer 5 at an entry point, wherein the distance between the exit point and the entry point is 2 mm or less, in particular 1 mm or less.

[0054] The density of the exposed areas, in particular the number of loop-shaped areas, per area of ​​the carrier layer 5 can be 10 / cm 2 or more, especially 20 / cm 2 or more, but less than 200 / cm 2 be.

[0055] The second carrier layer 5 may comprise a woven and / or knitted fabric made of mono- and / or multifilament fibers.

[0056] The carrier layer 5 in FIG. 3 is preferably the carrier layer 5 from FIGS. 1 and 2. The second fibers 1, 2, 3, 4 are preferably the cleaning elements 1, 2, 3, 4 from FIGS. 1 and 2.

[0057] The second fibers 1, 2, 3, 4 are then arranged in a strand-like manner, of which at least one second fiber 1, 2, 3, 4 extends along an optionally curved strand axis 1A, 2A, 3A, 4A, the cutting surface 1C, 2C, 3C, 4C of this at least one second fiber in one, preferably each, strand cutting plane 1B, 2B, 3B, 4B extending perpendicular to the strand axis 1A, 2A, 3A, 4A has an aspect ratio, that is to say a ratio of the greatest extent L to the extent W in a transverse direction running perpendicular thereto of 5 or more, in particular 10 or more, preferably 15 or more, but 100 or less, in particular 50 or less, preferably 30 or less.

[0058] At least one of the second fibers 1, 2, 3, 4 can preferably have an approximately trapezoidal, in particular rectangular, hollow, or trilobal cross-sectional area, preferably in a strand cutting plane 1B, 2B, 3B, 4B. These implementations are particularly effective with regard to wound and / or skin cleansing. However, other cutting surfaces or cross-sectional areas are conceivable.

[0059] As shown in FIG. 3, the first carrier layer 22 and the second carrier layer 5 together form a pocket 12 designed to receive a hand 23 of a user of the wound cleansing product between the two carrier layers 5, 22, which hand 12 the user inserts into the pocket 12 to clean the skin and / or wound using the second fibers 1, 2, 3, 4 or to clean the skin and / or wound using the first fibers 21. On the back of the carrier layer is a surface 9 (see FIG. 1), which can be the inside of the pocket 12.

[0060] The pocket 12 enables a user - after inserting a hand 23 into the pocket 12 - to easily rotate the wound cleansing product 100 around the longitudinal axis of the hand 12, preferably by 180° (e.g., by guiding a corner of the first and / or second carrier layer 5, 22 with the user's other hand) in order to switch between using the first fibers 21 and the second fibers 1, 2, 3, 4 on the wound or skin. This allows for quick and flexible, yet hygienic, use of the wound cleansing product. In addition, by directly acting on the first carrier layer 22 or the second carrier layer 5 (depending on the current orientation of the wound cleansing product), the dosage of manual pressure and rubbing speed on the wound or skin can be carried out particularly effectively and precisely.

[0061] In the textile industry, separation lanes are created by deliberately omitting individual threads in the spacing zone and in the two outer surfaces. These threads, such as elastane threads, hold the fabric web together until it has completed the finishing process. Afterward, the fabrics are separated by cutting and / or tearing the (elastane) threads in the separation lanes. Due to the elasticity of the material, the thread ends slide back into the mesh and are no longer visible.

[0062] During the manufacture of the wound cleansing device 10 according to the invention and the wound cleansing products 10, 100 according to the invention, a separation channel is incorporated into the web of the carrier layer from which the individual devices or products are cut. This separation channel, preferably with a width of approximately 3 to 8 mm, particularly preferably approximately 5 mm, serves to prevent fraying of the abrasive wound cleansing areas near the edges.

[0063] The description and figures describe preferred embodiments of the invention claimed by the following claims. The optional features disclosed in the above description, claims, and drawings can be used both individually and in any combination to implement the invention claimed here according to the appended claims in its various forms.

[0064] The various aspects and embodiments described above may be combined to create yet further embodiments. These and other changes may be made to the embodiments in light of the above detailed description. In general, the terms used in the following claims should not be construed to limit the claims to the specific aspects and embodiments disclosed in the description and claims, but rather to encompass all possible embodiments, along with the full scope of equivalents to which such claims are entitled.
