Abstract
Description
[0001] The present invention relates to a textile planar material for application to the human or animal body and for receiving electrical and / or electronic components for measurement and / or control purposes in medical technology.
[0002] A multilayered textile planar material is known from US 2021 / 0118427 A1, which has a cavity for receiving an electronic control unit, wherein the electronic control unit is embedded in the fabric and includes contact points that interact with conductive yarns disposed in the cavity and incorporated into the fabric to transmit electrical signals.
[0003] The basic objective of this invention is to provide a textile planar material of the type described above, which can be manufactured using a single weaving process and is suitable for reliably accommodating electrical and / or electronic components. Electrical and / or electronic components are particularly understood to include microcontrollers, rechargeable batteries, batteries, sensors for acquiring body and motion signals, and actuators acting on the body.
[0004] Textile flat materials should be preferably suitable for long-term and repeated use. In particular, textile flat materials may also be used to assist and monitor wound treatment and / or wound care, especially as wound dressings or integrated into wound dressings or wound bandages in a broad sense.
[0005] "Measurement for medical purposes" is particularly understood to be the recording of (biological) physiological signals or potentials, such as skin resistance, heart rate, and body movement.
[0006] "Medical technology control purposes" are particularly understood as the control and / or action on the body within the scope of diagnosis, treatment, rehabilitation and / or self-tracking, such as inducing body movement, electrical stimulation of muscles and / or nerves.
[0007] To achieve this objective, a textile planar material with the following features is proposed according to the present invention.
[0008] Therefore, a textile planar material is proposed, designed as follows. The textile planar material includes: a longitudinal direction; a transverse direction extending laterally to the longitudinal direction; an extending plane; a thickness direction orthogonal to the extending plane; at least one carrier segment extending in the longitudinal direction and having a carrier layer; at least one pocket segment extending in the longitudinal direction and adjacent to the carrier segment in the longitudinal direction and having at least one pocket for receiving electrical and / or electronic components, wherein the at least one pocket includes a first pocket layer facing the body and a second pocket layer facing away from the body, defining a pocket space between the first pocket layer and the second pocket layer, wherein the at least one pocket has at least one pocket opening accessible in the transverse direction, wherein the textile planar material includes warp yarns arranged in the longitudinal direction and weft yarns arranged in the transverse direction, the warp and weft yarns constituting the carrier layer, the first pocket layer and the second pocket layer, wherein at least one flexible electrical conductor extending in the longitudinal direction and arranged at least partially in a floating manner is provided in the thickness direction, between the first pocket layer and the second pocket layer.
[0009] Manufacturing textile planar materials using weaving processes allows for the continuous production of both the planar material and pockets disposed therein or on it. Arranging pockets within pocket sections of the textile planar material enables the targeted positioning of electrical and / or electronic components that can be accommodated therein. The pockets are accessible on both sides, or preferably on one side. Furthermore, within the pocket sections, improved and more reliable electrical connections can be achieved between electrical and / or electronic components and conductors by incorporating flexible electrical conductors arranged in a floating manner between the pocket layers. Because the conductors are arranged in a floating manner, a larger area of connection can be achieved compared to point-like connections known from the prior art between components and conductors.
[0010] In addition, the first pocket layer facing the body protects the skin from unintended contact with the contained electrical and / or electronic components. The second pocket layer facing away from the body at least partially covers the electrical and / or electronic components and prevents unintended external contact and / or action on the electrical and / or electronic components contained in the pocket.
[0011] Advantageously, the floating electrical conductor can be composed of conductive filaments, conductive wires, or conductive copper wires. The conductor is preferably braidable and capable of elastic deformation, particularly bending and / or stretching, along and / or orthogonal to the longitudinal direction. Furthermore, it is conceivable that the conductor comprises multiple filaments (especially fiber bundles) or multiple copper wires (especially copper strands composed of multiple copper wires) arranged parallel to each other in the longitudinal direction.
[0012] When referring to electrical conductors here, it means that such electrical conductors include conductive materials, especially those coated with or formed of conductive materials. Here, a conductor considered to be conductive has a resistivity of at most 2000 Ohm / m, preferably at most 1000 Ohm / m, and more preferably at most 500 Ohm / m. This means that, in conventional resistance measurements, a conductor segment of 1 m in length has a resistance of at most 2000 Ohm, or at most 1000 Ohm, or at most 500 Ohm.
[0013] In principle, in a fabric, warp and weft yarns are interwoven. For example, in a plain weave, the weft yarns alternately pass over and under the warp yarns, and the warp yarns alternately pass over and under the weft yarns. In contrast to a plain weave, when the conductors are arranged in a floating manner, the conductors are not alternately arranged over and under the weft yarns, but rather extend in a floating manner over several, preferably multiple, weft yarns.
[0014] In the following text, the distance between two consecutive connection points is referred to as the floating distance. It has proven advantageous that the floating distance of the electrical conductor in the pocket section is between 5 mm and 100 mm, especially between 5 mm and 50 mm, preferably between 5 mm and 30 mm, and most preferably between 10 mm and 20 mm.
[0015] Because the conductor extends in a floating manner within the pocket section, the electrical conductor is easily accessible within the pocket, making it possible, for example, to cut the electrical conductor with scissors, to adjust its insulation or coating, and / or to provide a plug.
[0016] It is also conceivable that the electrical conductors are arranged entirely in a floating manner within the pocket segment, i.e., without any connection points to the pocket segment. These connection points may exist within the carrier segment and / or in the transition between the carrier segment and the pocket segment. Arranging the electrical conductors entirely in a floating manner within the carrier segment provides a high degree of flexibility when connecting them to the components to be placed, as the electrical conductors can move or shift within the pocket segment due to the lack of connections.
[0017] In an alternating design scheme for the textile planar material, opposite to the carrier sections in the longitudinal direction, another carrier section is adjacent to a pocket section, wherein the pocket sections are arranged between these carrier sections in the longitudinal direction. Therefore, in this embodiment, the textile planar material is arranged in a "carrier section-pocket section-carrier section" pattern in the longitudinal direction.
[0018] It can also be shown to be advantageous that, in the longitudinal direction opposite to the pocket sections, there are additional pocket sections adjacent to the carrier sections, wherein the carrier sections are arranged between these pocket sections in the longitudinal direction. Thus, in this additional embodiment, the textile planar material is arranged in a "pocket section-carrier section-pocket section" configuration in the longitudinal direction.
[0019] What can prove particularly advantageous is that the textile planar material is formed generally continuously in the longitudinal direction, with carrier sections and pocket sections alternating accordingly. This allows for full utilization of the advantages of continuous manufacturing using weaving techniques.
[0020] What has proven particularly advantageous in accommodating electrical and / or electronic components is that the first and second pocket layers are at least partially placed loosely against each other or one above the other in the pocket section. Thus, components can be easily introduced into the pocket.
[0021] Furthermore, in terms of continuous manufacturing, it is advantageous that the warp yarns extending in the longitudinal direction are merged at the transition point from the pocket section to the carrier section to form a carrier layer. If the woven planar material has pocket sections and carrier sections formed sequentially in the longitudinal direction, then multiple layers of pocket sections and single layers of carrier sections alternate. This has the advantage that the same warp yarn can be used to form both the carrier layer and the pocket layer simultaneously, and that a stable carrier layer can be formed within the carrier section.
[0022] Furthermore, advantageously, the at least one electrical conductor is arranged on the carrier layer, particularly partially surrounded by the carrier layer or otherwise held thereon. This restricts the movement of the conductor in the transverse direction by the warp yarns. For further securing the conductor, it has proven advantageous that the conductor is connected at least in a point-like manner to the carrier layer. For this purpose, the electrical conductor can be woven into the carrier layer, or the electrical conductor can be secured to the carrier layer by means of retaining devices.
[0023] In a further improvement of the planar material according to the invention, a plurality of electrical conductors extending substantially parallel to each other in the longitudinal direction may be provided, wherein these electrical conductors are spaced apart from each other in the transverse direction, such that there is no direct contact between two or more electrical conductors when the textile planar material is used as intended. Therefore, different signals can be transmitted in and along the textile planar material. Furthermore, reliable connections between the conductors and the different contacts of the received electrical and / or electronic components can be ensured accordingly.
[0024] Furthermore, it is advantageous that the electrical conductor is at least partially insulated within the carrier section. This prevents unintended contact or touch of the electrical conductor by nearby skin or from the outside.
[0025] It can also prove particularly advantageous that the at least one electrical conductor is at least partially uninsulated or has its insulation removed in the pocket section, thereby enabling the establishment of electrical contact between the at least one electrical conductor and the received electrical and / or electronic components. The electrical conductor may be provided with exposed, uninsulated areas before being woven into the fabric. Alternatively, the electrical conductor may be introduced into the fabric material completely insulated, and the insulation may subsequently be removed in the pocket section as needed. Contact between the electrical conductor and the received component preferably occurs on the side of the component away from the body, so that the electrical conductor does not form a raised profile on the side facing the body.
[0026] An improved embodiment of the planar material according to the invention proposes that at least one electrical conductor is cut in a pocket segment, thereby giving the electrical conductor two free conductor ends, particularly for contact with electrical and / or electronic components. Since the electrical conductor is floating in the pocket segment, it can be easily cut (e.g., with scissors) after being introduced into the planar material.
[0027] Now, at least one plug can be provided at the free conductor end of the cut electrical conductor, thereby enabling electrical contact to be established with the received electrical and / or electronic components via a plug-in connection. For this purpose, the plug and the component each have corresponding connection ends. Therefore, components can be easily connected and removed by establishing and disconnecting the plug-in connection.
[0028] According to another embodiment, it has proven advantageous that at least one pocket is closed by merging the first pocket layer and the second pocket layer in the lateral direction opposite to the pocket opening. Thus, in a continuous manufacturing process, a textile flat material can be woven with pockets that have a pocket opening on one side and are closed on the other side in the lateral direction.
[0029] Opposite to the pocket opening in the transverse direction, a side region is adjacent to the at least one pocket, wherein the first pocket layer and the second pocket layer are connected to each other in a planar manner in the side region, and in particular, the weft yarns of the first pocket layer and the second pocket layer extending in the transverse direction are interwoven with the warp yarns of the first pocket layer and the second pocket layer extending in the longitudinal direction in the side region. Furthermore, in terms of the continuous manufacturability of the planar material, it is conceivable that the transverse extension dimension of the pocket section generally corresponds to the transverse extension dimension of the carrier section.
[0030] Furthermore, advantageously, a positioning device is provided in or within the pocket for positioning and / or locking electrical and / or electronic components that can be placed in the pocket. Accordingly, the components can be reliably held in the pocket and preferably fixed in a defined position, such that the contacts and conductors of the electrical and / or electronic components are abutted or interconnected. In particular, hooks on the components and corresponding undercuts in the pocket section may be provided as positioning devices. Magnets on the components and ferromagnetic materials in the pocket section are also conceivable.
[0031] In another particularly advantageous embodiment, the carrier section and / or pocket section are provided with longitudinally extending, elastically stretchable warp yarns and / or transversely extending, elastically stretchable weft yarns. This ensures a good fit of the textile material to the body. Furthermore, the elastic yarns in the pocket section can be designed to keep introduced electrical and / or electronic components enclosed, thereby preventing the components from falling out of the pocket. Additionally, yarns with different elasticities can be provided in the first and second pocket layers. In particular, it is conceivable that the second pocket layer provides yarns with greater elasticity than the first pocket layer. This ensures that, when components are introduced, the second pocket layer, away from the body, yields more than the first pocket layer, pushing the components away from the skin and thus reducing pressure on the patient's skin.
[0032] The elasticity of the aforementioned elastic yarn can be simulated and determined according to DIN EN ISO 13934-1. Here, yarn sections of 80 mm in length are used instead of the planar specimens mentioned in the standard. The elasticity of the yarn is determined based on the maximum tensile elongation of the yarn used.
[0033] It has proven advantageous that the maximum tensile elongation of the elastic yarn is at least 1.10 times, particularly at least 2.0 times, and further particularly at least 5.0 times, particularly at least 10 times, and particularly at least 20 times that of the other yarns used. Furthermore, it has proven advantageous that the maximum tensile elongation of the elastic yarn is in the range of 10% to 300%, particularly in the range of 10% to 200%, advantageously in the range of 10% to 100%, and preferably in the range of 10% to 20%.
[0034] The subject of this invention is also a holding or supporting device for electrical and / or electronic components, comprising a textile planar material according to the invention. Here, the textile planar material is preferably pre-assembled as a neck strap, wristband, forehead band, chest strap, or kinesio-tape.
[0035] It is also conceivable that the flat material is designed as a bandage or dressing, wherein the continuously manufactured flat material is cut to a defined length. Thus, the flat material forms end regions with free ends in the longitudinal direction. These end regions can then be joined together, particularly sewn, welded, and / or glued, to form a loop-shaped bandage or dressing. Alternatively, carrier sections can be provided in the end regions in the longitudinal direction, where Velcro or adhesive can be used, in particular. Velcro allows the dressing to be specifically matched to adjacent body parts. Adhesive allows the flat material to be used as a patch.
[0036] Furthermore, protection is claimed for a medical-technical measuring and / or control device used on a human or animal body, comprising a holding or supporting device according to the invention and electrical and / or electronic components held thereon and in electrical contact therewith, particularly a microcontroller, battery, accumulator, sensor for acquiring body signals and / or motion signals, and / or components for generating and / or outputting electrical signals to the body. Here, it is conceivable that the components are connected to the at least one electrical conductor via a plug-in connection. In the case of a rectangular component, this plug-in connection can be provided on the side of the component facing the carrier section, the side facing or away from the through-opening, and / or the side facing the pocket layer.
[0037] Other features, details and advantages of the invention will become apparent from the accompanying drawings and the following description of preferred embodiments of the textile planar material according to the invention.
[0038] In the attached diagram:

[0044] Figure 5b A schematic diagram of a bandage in use on a person's upper arm is shown, wherein electronic components are incorporated within the bandage.
[0045] These accompanying drawings illustrate the textile planar material 2 according to the invention and partially indicate its structure in a highly schematic manner. The planar material 2 is provided for attachment to a human or animal body 4 and for receiving at least one electrical and / or electronic component 6. The textile planar material 2 extends along a longitudinal direction 8, a transverse direction 10, and is in contact with... Figure 1 The extension extends on the plane 12 that coincides with the plane of the diagram. Furthermore, a thickness direction 13, extending orthogonally to the extension plane 12, is introduced, which can extend from... Figure 3 To be seen.
[0046] Figure 1 A top view of the section 18 of the textile planar material 2, represented by a rectangular frame 16, facing the body side 14 is shown. Figure 2 A three-dimensional illustration of the textile planar material 2 is shown, wherein the side facing the body 14 is oriented upwards, while the side away from the body 20 (not visible) is oriented downwards.
[0047] Section 18 of the textile flat material 2 includes two pockets 22, which are exemplary designed as rectangles in the case shown here. Figure 1 (Represented by frame 24), for receiving electrical and / or electronic components 6. Pocket 22 extends in the longitudinal direction 8 over a pocket length 26 and in the transverse direction 10 over a pocket width 28. Pocket 22 is accessible in the transverse direction 10 via pocket openings 30 provided at the lateral edges of segment 18. Opposite to the pocket openings 30 in the transverse direction 10, a side region 32 of segment 18 is adjacent to pocket 22. Side region 32 extends in the longitudinal direction 8 over a pocket length 26 and in the transverse direction 10 between pocket 22 and the lateral edges of segment 18.
[0048] The corresponding pocket 22 area, together with the adjacent side area 32, constitutes a pocket section 34 of the textile planar material 2 or section 18. A carrier section 36 is provided or arranged between these two pocket sections 34 in the longitudinal direction 8.
[0049] As will be further elaborated below, the textile planar material 2 according to the invention can be continuously manufactured in the longitudinal direction 8, thus enabling the obtaining of the section 18 of the planar material 2 shown in the drawings as a continuous longitudinal section of the planar material 2 by means of the continuously manufactured strip or belt of the textile planar material 2 according to the invention. Therefore, it is conceivable that the section 18 may have one or more pockets 22, between which carrier sections 36 are correspondingly arranged in the longitudinal direction 8 (as shown).
[0050] exist Figure 2 The same can also be seen in section 18 of the textile flat material 2, where it can be seen that the textile flat material 2 includes a first pocket layer 38 facing the body and a second pocket layer 40 facing away from the body in the corresponding pocket section 34. In the preferred embodiment, the first pocket layer 38 facing the body and the second pocket layer 40 facing away from the body can be loosely attached to each other and / or can be unfolded in such a way that the pocket space 42 is defined by the first pocket layer 38 and the second pocket layer 40. Thus, electrical and / or electronic components 6 can be accommodated in the pocket space 42.
[0051] With the help of Figures 2 to 4 As can be seen, the first pocket layer 38 facing the body and the second pocket layer 40 facing away from the body are combined to form the carrier layer 44 of the textile provided in the carrier section 36. The carrier layer 44 extends in the transverse direction 10 between the lateral edges of the section 18 of the planar material 2, that is, it extends over the entire width of the planar material. In the longitudinal direction 8, the carrier layer 44 extends between the two pockets 22.
[0052] Preferably, in addition to the function of receiving electrical and / or electronic components 6, the textile planar material 2 also serves to electrically connect the received components 6 to other electrical and / or electronic components located outside the pocket 22. For example, these components may be arranged in another pocket 22 of the same textile planar material 2, or, for example, may be formed as electrodes and arranged on another functional section of the electrode section of the textile planar material 2.
[0053] In this embodiment, for example, three electrical conductors 46 are provided for connection or contact with electrical and / or electronic components 6, which are introduced into the textile planar material 2. Figure 1In Figure 5, the electrical conductor 46 is indicated by a dashed line. The electrical conductor 46 is used to transmit signals away from the body, towards the body, and / or between two electrical and / or electronic components 6, wherein each electrical conductor 46 can transmit different signals. The electrical conductors 46 are arranged along the longitudinal direction 8 and are arranged to extend parallel to each other. In the carrier section 36, the electrical conductors 46 are connected to the carrier layer 44 in such a way that undesirable slippage of the electrical conductors 46 in the longitudinal direction 8 and / or the lateral direction 10 is prevented. Furthermore, the electrical conductors 46 are incorporated into the carrier layer 44 in such a way that contact between the electrical conductors 46 during normal use is prevented. Furthermore, in the pocket section 34, the electrical conductors 46 are not connected to the first pocket layer 38 and not connected to the second pocket layer 40. Therefore, the electrical conductors 46 are substantially exposed between the first pocket layer 38 and the second pocket layer 40 in the pocket 22, wherein the electrical conductors can be loosely attached to the first pocket layer 38 and / or the second pocket layer 40 from the inside.
[0054] The composition of the layers, pockets, regions, and sections of the textile planar material according to the present invention will be described below.
[0055] The first pocket layer 38, the second pocket layer 40, and the carrier layer 44 include warp yarns 48 extending in the longitudinal direction 8 and weft yarns 50 extending in the transverse direction 10, which are specifically designed to be non-conductive yarns.
[0056] exist Figure 2 The diagram schematically illustrates the direction of a single warp yarn 48 and a single weft yarn 50. The warp yarn 48 and weft yarn 50 are lowered from their zero positions and interwoven to form a second pocket layer 40 in the pocket section 34. Similarly, another warp yarn 48 and weft yarn 50 are raised from their zero positions and interwoven to form a first pocket layer 38. In the transition to the pocket section, the warp yarn 48 and weft yarn 50 are raised or lowered back to their zero positions. Thus, the warp yarn 48 extending in the longitudinal direction 8 that constitutes the first pocket layer 38 and the warp yarn 48 extending in the longitudinal direction 8 that constitutes the second pocket layer 40 are merged in the carrier section 36 to form a warp-knitted carrier layer 44. Correspondingly, the stable carrier layer 44 is formed by the warp yarn 48 and weft yarn 50 at their zero positions.
[0057] Correspondingly, side region 32 is formed. The weft yarns 50 that correspondingly form the first pocket layer 38 and the second pocket layer 40 are raised or lowered in the region of pocket 22. In the transition from pocket 22 to side region 32, the corresponding weft yarns 50 are lowered or raised back to zero and interlaced with additional warp yarns 48, thereby allowing a single textile layer equivalent to the carrier layer 44 to be formed in side region 32. However, alternatively, the two pocket layers 38, 40 may subsequently be connected to each other in any manner.
[0058] Especially from Figure 2 and Figure 3 The orientation of the conductor 46 can be observed. In the carrier section 36, the conductor 46 is almost completely covered by the warp yarns 48 and weft yarns 50. In the pocket section 34, the conductor 46 is arranged, for example, entirely in a floating manner. Therefore, the conductor 46 is not connected to the first pocket layer 38 or the second pocket layer 40 in the pocket section 34. Within the range of gaps and elasticity, the conductor 46 can move freely within the pocket 22, wherein the conductor 46 has two corresponding connection points in the transition between the pocket section 34 and the carrier section 36. Therefore, the floating distance 47 of the conductor 46 in the pocket section 34 approximately corresponds to the pocket length 26. It is conceivable, by way of example, that the conductor 46 is arranged floatingly at the first pocket layer 38 and / or the second pocket layer 40 with a floating distance 47 between 5 mm and 30 mm. In the exemplary case where the pocket length 26 is 30 mm and the floating distance 47 is 5 mm, the electrical conductor 46 is connected in the transition between the pocket section 34 and the carrier section 36, and also at five other connection points. In this case, six floating regions of the electrical conductor 46 are formed in the pocket section 34. Furthermore, in the case of multiple electrical conductors 46, each electrical conductor 46 can be arranged in different ways in the pocket section 34 and / or the carrier section 36, especially in different floating ways. In the pocket section, the floating distance of the electrical conductor 46 can preferably be between 5 mm and 100 mm, especially between 5 mm and 50 mm, preferably between 5 mm and 30 mm, and preferably between 10 mm and 20 mm.
[0059] exist Figure 3In the diagram, the floating arrangement of the electrical conductor 46 is represented by wavy dashed lines. In the left pocket 22, the electrical conductor 46 is continuous, into which electrical and / or electronic components 6, for example, with open contacts, can be placed, allowing a close-fitting connection between the component 6 and the electrical conductor 46 by aligning the component 6 within the pocket 22. Correspondingly, it is meaningful that the electrical conductor 46 can make electrical contact in the pocket section 34. The electrical conductor 46 can be introduced into the textile planar material 2 along with an insulating layer. Therefore, the insulating layer of the electrical conductor 46 must be removed in the pocket section 34. Furthermore, it is conceivable that the electrical conductor 46 is partially without an insulating layer, and that the non-insulated areas are aligned with the pocket section 34 during the introduction of the electrical conductor 46 into the planar material 2. In the right pocket 22, the electrical conductor 46 is cut using scissors. Thus, the electrical conductor 46 has two free conductor ends 52. Depending on the conductor type, the free conductor ends 52 can be connected to the component 6 to be placed inside. For example, the free conductor end 52 on the left can be attached (especially glued or soldered) to the contacts of the component 6 to be inserted. A plug 54 is provided at the conductor end 52 on the right, by which a plug-in connection can be established with the component 6 to be inserted. The electrical and / or electronic component 6 correspondingly has a slot corresponding to the plug 54.
[0060] exist Figure 4 The diagram illustrates a pocket 22 of a planar material 2 according to the invention. An electronic component 6, comprising four slots for a plug 54, is placed in the pocket 22. In this case, the planar material 2 comprises two electrical conductors 46, each equipped with a plug 54 at its free conductor end 52. The plug 54 is inserted into the electronic component 6 along the longitudinal direction 8 or the thickness direction 13. To simplify and improve the alignment of electrical and / or electronic components, positioning devices 55 are provided at the component 6 and the pocket 22. These positioning devices work together during the insertion of the component 6, causing the component 6 and the pocket 22 to engage and / or providing resistance to the user. For example, magnets, hooks with undercuts, and / or adhesives can be envisioned as positioning devices 55.
[0061] Figure 5a and Figure 5bAn exemplary illustration is shown of a textile planar material 2 according to the invention, assembled into a bandage 60 for placement on an arm. The bandage 60 includes a pocket 22 and two carrier layers 44 adjacent to the pocket 22 in the longitudinal direction 8. The bandage 60 and electronic components 6 received in the pocket 22 constitute a device 62 for medical-technical measurement and / or control purposes. In the case of the bandage 60, each carrier layer 44 terminates in the longitudinal direction 8 at a free carrier end 56. A retaining device 58 may be provided at the free carrier end 56 of the carrier layer 44 to create adhesion or fixation on the arm. For example, the retaining device 58 may be designed as an adhesive point so that the planar material 2 can be adhered to the skin as a patch. Figure 5b Alternatively shown is a bandage 60 having Velcro fasteners at the free carrier ends 56 of the carrier layer 44. Thus, the free carrier ends 56 can be overlapped, allowing the planar material 2 to be individually secured to the arm. Furthermore, it is conceivable that the free carrier ends 56 are sewn together, enabling the production of a bandage 60 with a defined circumference using the planar material 2. In this case, it is particularly advantageous that the planar material 2 has elastic yarns 48, 50, allowing for the production of a stretchable, skin-conforming bandage 60. The elastic yarns 48, 50 can also be advantageously used in other embodiments.
[0062] Therefore, it is advantageous even when the elastic yarns 48, 50 are located in the area of the pocket layers 38, 40, so that the element 6 received therein is surrounded by one or two pocket layers 38, 40 and thus cannot fall out of the pocket 22.
