Band for enclosing a leg or arm region of a living being

Description

[0001] The invention relates to a bandage, in particular a ready-to-use secondary bandage for enclosing a leg or arm area of ​​a living being.

[0002] The use of secondary dressings to secure and protect primary wound dressings during medical treatments, such as wound care, is well-established. These types of dressings are used in inpatient settings, such as hospitals, nursing homes, and other facilities, as well as in outpatient settings, such as home care for the elderly. Products such as wrap dressings, tubular bandages, and padding dressings are frequently used, some of which require multiple layers. This necessitates trained, professional expertise and precludes use by laypersons. An example of such a dressing is a wrap dressing for wound care on body parts like legs or arms. When applying the dressing, it is crucial to prevent the primary wound dressing from slipping and to avoid the formation of wrinkles to prevent pressure sores.Furthermore, the bandage must be applied snugly and evenly to the body part without exerting dangerous overcompression. Subsequent readjustment is difficult because it requires re-wrapping or completely cutting the bandage. This can cause the primary wound dressing to slip or be damaged, resulting in increased time and costs. DE202012102576 discloses a veterinary bandage that can be applied to the limb as easily as possible and ensures a secure fit and defined compression pressure.

[0003] The object of the present invention is therefore to provide a ready-to-use dressing, in particular a ready-to-use secondary dressing, which combines the advantages of padding dressings, tubular dressings and elastic bandages in one product, is easy to handle without requiring specially trained expertise when applying the dressing, and at the same time provides an improved fit and avoids wrinkling.

[0004] This problem is solved by a device according to claim 1. Advantageous embodiments and further developments of the invention are described in the dependent claims.

[0005] In particular, this task is solved by a bandage for enclosing a leg or arm area of ​​a living being, comprising: an elongated, tubular bandage section, which is at least partially simply slit lengthwise and which is adapted to elastically enclose the leg or arm area when applied; and a closure section with closure elements, which is firmly connected to one end of the slit area of ​​the bandage section in order to detachably close the slit area by means of the overlapping connection of the adjacent ends of the slit area using the closure elements. It is provided that the bandage section has different compression zones in the longitudinal direction, each with different radial compression strengths transverse to the longitudinal direction or different elastic moduli of the bandage material. The bandage component is made from at least one section (Z) of a stretch material. The stretch material comprises either elastomeric threads of different thicknesses, which create different compression strengths in the respective compression zones, or elastomeric threads with different pretensions, which create different compression strengths in the respective compression zones (K1, K2).

[0006] It is therefore intended to be an adaptable, ready-to-use calf, lower leg or forearm bandage that covers the calf area or lower leg from the ankle to the knee, or the forearm from the elbow to the hand.

[0007] The different compression zones ensure a good fit of the bandage to a leg or arm area, without requiring any special expertise when applying the bandage.

[0008] The different compression zones can be assigned to predetermined areas of a thigh, especially a lower leg, or an arm, especially a forearm.

[0009] In this context, a first compression zone in the bandage can be assigned to the waist area at the knee and / or ankle of the lower leg, and a second compression zone can be assigned to the calf area of ​​the lower leg. The first compression zone can have a higher compression level than the second. This further reduces the risk of the bandage slipping, as it applies greater compression to the knee and / or ankle. At the same time, the second compression zone prevents the bandage from being too tight or exerting excessive pressure, for example, on a wound.

[0010] The bandage component can be made from at least one cut piece of a flat material comprising a nonwoven material.

[0011] The bandage part is made from at least one piece of stretch material.

[0012] The stretch material can have an elongation of at least 50% and a recovery capacity of 30% to 100%.

[0013] In one embodiment, the stretch material can have a 2-way stretch fabric, wherein one stretch direction extends in the transverse direction of the bandage.

[0014] In another embodiment, the stretch material can be a 4-way stretch fabric, with one stretch direction extending transversely and another longitudinally along the bandage. This provides additional flexibility. Depending on the bandage requirements, either the 2-way stretch fabric or the 4-way stretch fabric can be used.

[0015] The stretch material includes eitherElastomer threads or elastane fibers of varying thicknesses create different compression strengths in the respective compression zones. By using elastomer threads of different thicknesses, zones can be formed where the thicker thread diameters result in a higher compression strength than zones with thinner thread diameters.

[0016] Additionally or alternatively includes The stretch material consists of elastomer threads or elastane fibers with different pretensions, creating different compression strengths in the respective compression zones.

[0017] The bandage may include, in addition to the slit section, a tubular, closed distal section which, when applying the bandage, is pulled over a foot or hand of the animal and, when the bandage is in place, lies adjacent to the foot or hand. This can facilitate handling the bandage. For example, the closed distal section prevents the bandage from slipping over an ankle or wrist, allowing it to be closed quickly and easily.

[0018] In its applied state, the bandage section can compressively enclose the ankle area of ​​a foot in its tubular, closed distal area and the calf area of ​​a lower leg in its slit area.

[0019] The closure element can consist of individual hook-and-loop fastener pieces punched out of a hook-and-loop strip, each individually attached to the bandage. These hook-and-loop fastener pieces allow for easy and secure closure of the bandage ends in the slotted area.

[0020] In another embodiment, the closure part can also be designed as a one-piece multi-hook closure part, which is connected to the bandage part on one side in its non-hook area and has protruding closure elements on its opposite side in its hook area, which are formed by punching the hook and loop fastener tape.

[0021] Furthermore, the bandage part can be made from two identical cut pieces that are joined together by means of a seam that is elastic in the seam direction.

[0022] The bandage section can have a shape adapted to the calf area of ​​a lower leg, making it an even more precise fit.

[0023] Furthermore, the bandage can be designed as a hygienic disposable product.

[0024] The invention will be explained in more detail below, for example, with reference to the drawings. The drawings show: Fig. 1A a schematic perspective view of a assemblage according to an embodiment of the invention; Fig. 1B a schematic perspective view of the assembly according to an embodiment of the invention in the closed state; Fig. 1C a schematic side view of a ligament part of the ligament according to an embodiment of the invention; Fig. 1D a schematic side view of the ligament part of the ligament according to an embodiment of the invention; Fig. 1Ea schematic exploded view of the assembly according to an embodiment of the invention; Fig. 1F a schematic perspective view of the assembly according to a further embodiment of the invention in the closed state; Fig. 2 a schematic side view of the assembly according to several embodiments of the invention; Fig. 3 Schematic cutting patterns for the production of the bandage according to several embodiments of the invention; and Fig. 4 a schematic representation of the production of the bandage according to an embodiment of the invention.

[0025] In the following, the same reference symbols are used for identical and equivalent components.

[0026] Fig. 1AFigure 1 shows a schematic perspective view of a bandage 100 for enclosing a leg or arm area of ​​a living being. The living being can be a human or an animal. The bandage 100 comprises an elongated, tubular bandage part 10, which is at least partially simply slit in the longitudinal direction LR. This is shown in Fig. 1A simplified by an arrow pointing to the slotted area B1. When applied, the bandage part 10 elastically encloses the leg or arm area. In this context, it shows Fig. 1B The bandage 100 is shown in its closed state, with a leg area illustrated as an example. An arm area is also possible.

[0027] The bandage 100 further comprises a closure part 20 with closure elements 22, 22'. The closure part 20 is firmly connected to one end of the slotted area B1 of the bandage part 10 in order to detachably close the slotted area B1 by means of the overlapping connection of the adjacent ends of the slotted area B1 by means of the closure elements 22, 22'. This is shown in Fig. 1A and Fig. 1B Simplified illustration.

[0028] The length of the slit can vary depending on the requirements of the dressing 100. For example, it can be greater than 10%, or greater than 20%, or greater than 30%, or greater than 40%, or greater than 50%, or greater than 60%, or greater than 70%, or greater than 80%, or greater than 90%, or greater than up to 100% of the total length L of the dressing part 10. It is also possible that the length of the slit is 100% of the total length L, meaning that the length of the slit area B1 is equal to the length LR, and the tubular dressing part 10 is completely slit or cut lengthwise L.

[0029] The locking part 20 can be formed from several elements 22A, 22B, 24, 26, which in Fig. 1C is shown. Fig. 1CFigure 1 shows a schematic side view of the bandage part 10, wherein a closure element 22 can be made from a handle part 22A and a hook part 22B, such as a hook and loop fastener. The handle part 22A allows a user to grasp the closure element 22. In this context, another embodiment of a closure element 22' is shown on the right side in the figure. Fig. 1C shown, which is designed as a closure flap with a hole or recess in the hook part 22B. The recess can be circular, oval, or elliptical in shape. This enhances grip and provides better control for a user's finger. The hole acts as a fingertip grip. This design allows for a flat, wrinkle-free fit on curved surfaces, which in turn can result in improved adhesion and reduced wrinkling. In addition to the Fig. 1CFurther configurations are possible beyond the illustrated closure flap with hole or oval recess. The closure part 20 can also include an elastic part 24 and a connecting part 26. The connecting part 26 can, for example, connect the closure part 20 to the bandage part 10 by gluing or welding.

[0030] Furthermore, the bandage part 10 has different compression zones K1, K2 in the longitudinal direction LR, each with different radial compression strengths transverse to the longitudinal direction LR (i.e. in the transverse direction QR).

[0031] This ensures an optimally fitted application of the bandage 100 at the appropriate points on the leg or arm. Compression zones K1 and K2 simplify handling, as no special prior knowledge is required and the appropriate compression is pre-defined at each point. Furthermore, this reduces wrinkling.

[0032] The different compression zones K1, K2 can, for example, be assigned to predetermined areas of a thigh, in particular a lower leg, or of an arm, in particular a forearm. Fig. 1D Figure 1 shows a schematic side view of bandage part 10, illustrating compression zones K1 and K2. As shown in Figure 10, the compression zones K1 and K2 are shown in Figure 1. Fig. 1D in connection with the Figures 1A and 1B As can be seen, a first compression zone K1 in bandage part 10 can be assigned to a waist area at the knee and / or ankle of the lower leg. Furthermore, a second compression zone K2 in bandage part 10 can be assigned to a calf area of ​​the lower leg. The first compression zone K1 can have a higher compression strength than the second compression zone K2, which is simplified by the horizontal lines in Fig. 1DThe diagrams shown are representative of the corresponding material threads and their spacing. The elastic threads, elastane threads, elastane fibers, or elastomeric threads will be discussed in detail later with reference to... Fig. 2 described.

[0033] The dimensions of the in Fig. 1D The dimensions of the dressing component 10 shown can vary. For example, the upper diameter D1 can range from 50 mm to 150 mm. The middle diameter D2 can range from 100 mm to 200 mm. And the lower diameter D3 can range from 50 mm to 150 mm. The length L of the dressing component 10 can range from 100 mm to 400 mm. The length ratio of a compression zone K1, K2 to the total length L can range from 10% to 70%, or from 10% to 50%, or from 20% to 40%, or from 25% to 35%.

[0034] Fig. 1EFigure 1 shows a schematic exploded view of the bandage 100, showing that the bandage part 10 can be formed from two uniform blanks Z to be joined together, as well as the closure part 20 described above. Both blanks Z comprise the different compression zones K1 and K2, which can be simplified to Fig. 1E as indicated by arrows. The blanks Z can be joined together, for example, by ultrasonic welding at the corresponding cut edge sections A1, A1'. The cut edge sections A1, A1' of the respective blanks Z have a bent or curved shape, which is shown in the Fig. 1EThe example shown corresponds to a calf area or lower leg and results from a predefined cutting pattern. Here, the cut edge sections are S-shaped, with an upper convex curvature section having a radius of curvature between 300 mm and 450 mm in the calf area and a lower concave curvature section having a radius of curvature between 250 mm and 350 mm. The lower curvature section then transitions into a straight cuff section in the ankle area. Cut edge sections A2 and A2' are straight and are not connected to each other. They form the slit section B1 or an opening. In the upper cut Z, however, cut edge section A1 is connected to a similarly straight cut edge section C1 of the closure part 20. This can be done, for example, using the connecting part 26 described above.The cut edge sections A3, A3' are also joined together to form a closed, distal area B2, which will be described in detail later. As shown in... Fig. 1E As can be seen, the cut edge sections A3, A3' also have a curved or bent shape derived from the pattern, which, when connected, encloses an ankle. It is also possible to form the bandage part 10 in one piece. The production of the bandage 100 is described with reference to the Figures 3 and 4This will be explained in more detail later. The ratio of the lengths of the slit section B1 to the closed section B2 can be between 5% and 40%, or between 10% and 30%, or between 15% and 25%. In these cases, the closed section B2 can be easily pulled over the foot or hand, while at least more than half of the bandage 100 can still be closed by means of the closure element 20 with variable compression. Theoretically, the bandage section 10 can also have closed sections at both ends in the longitudinal direction L, with the slit section B1 then running between these sections. Since a closed section in the cuff area of ​​the knee makes applying the bandage rather difficult (and it has to be pulled over the wound area), this embodiment is included in the invention, but not considered the preferred embodiment.

[0035] The ratio of the first compression strength of the first compression zone K1 to the second compression strength of the second compression zone K2 can be greater than 1.5, or greater than 2, or greater than 3, or greater than 3.5, or greater than 4, or greater than 4.5. The compression strength of the first compression zone K1 at a waistband area, such as the one in Fig. 1A The knee and ankle areas shown may be the same. However, they can also differ. The number of compression zones in the Figures 1D, 1E , 2 , and 4The examples shown are illustrative, and further compression zones with different compression strengths are possible. While it is preferred that the compression strength of the first compression zone K1 be the same at both the waistband at the knee and at the ankle, a third compression zone can be provided at the waistband at the ankle instead of the first compression zone K1. This third compression zone's compression strength would differ from, or even deviate from, the compression strength of the compression zone at the knee. However, in this case, the compression strength of this third compression zone would also be greater than the compression strength of the second compression zone K2.The term compression strength is understood to mean a force or pressure that, when the bandage is applied, acts radially inwards on the body part enclosed by the bandage due to circumferential elasticity or restoring force within the bandage (for example, through incorporated elastane fibers or elastomeric threads in the circumferential direction transverse to the longitudinal direction L). In the area of ​​compression stockings, the following compression classes are used for the compression strength according to the invention: CCL1 (moderate compression with a compression pressure of 2.4 kPa to 2.8 kPa), CCL2 (medium compression with a compression pressure of 3.1 kPa to 4.3 kPa), CCL3 (strong compression with a compression pressure of 4.5 kPa to 6.1 kPa), and CCL4 (extra strong compression with a compression pressure greater than 6.5 kPa).In the field of compression stockings, compression classes CCL1 (moderate compression with a compression pressure of 2.4 kPa to 2.8 kPa), CCL2 (medium compression with a compression pressure of 3.1 kPa to 4.3 kPa), CCL3 (strong compression with a compression pressure of 4.5 kPa to 6.1 kPa), and CCL4 (extra-strong compression with a compression pressure greater than 6.5 kPa) are used for the compression strength according to the invention. The compression strength of the compression zones K1 and K2 of the bandage 100 according to the invention is preferably in the range of compression class CCL1, or in the range of compression class CCL2, or in the range of compression class CCL3, or in the range of compression class CCL4, depending on the application and intended use of the bandage 100.The term compression strength always refers to the compression strength of a bandage applied to a normally shaped lower leg or forearm. This compression strength results from an elasticity or tensile stiffness in the circumferential direction of the closed bandage 100 corresponding to the compression strength, due to the deflection and elongation of the bandage material. Thus, the term compression strength is to be considered equivalent to the elastic modulus of the bandage material (or the elastic support structure made of elastomeric threads) of a compression zone K1, K2 in the transverse direction QR or circumferential direction of the bandage 100.

[0036] In another embodiment, the bandage 100 can also be combined with additional products for medical treatment, such as a foot bandage. Fig. 1FAn example is shown in which the bandage 100 is formed with a sock S or footie. Such a sock is described, for example, in patent application DE 10 2016 104 206 A1.

[0037] In Fig. 3Schematic patterns for the production of the bandage 100 according to several embodiments are shown. On the left is a pattern for a calf area or a lower leg. The respective resulting cut edge sections A1, A2, A3 are indicated by arrows. However, the calf or lower leg pattern is only an example. The course of the cut edge sections A1, A2, A3 can vary depending on the pattern. On the right is a pattern for a calf area or a lower leg with a sock S. Here, another cut edge section A4 associated with the sock S is shown. The dashed line in both figures also indicates a resulting seam N, which is created when two identical or two similarly shaped cut pieces Z obtained from the pattern are joined together by ultrasonic welding.

[0038] The dressing component 10 can be made from at least one section Z of a flat material comprising a nonwoven fabric. Preferably, a nonwoven fabric intended for use in hospitals and nursing homes is used.

[0039] A nonwoven material is a structure made of fibers of limited length, continuous fibers (filaments) or cut yarns of any kind and origin, which have been joined and bonded together in some way to form a nonwoven (a layer of fibers, a nap of fibers).

[0040] Nonwoven fabrics can be made from synthetic and / or natural fibers. Synthetic nonwovens or blends of natural and synthetic fibers exhibit increased elasticity. For ecological reasons, the nonwoven fabric can consist almost entirely of natural fibers to ensure biodegradability. Examples of suitable fibers include modal or viscose. Furthermore, natural fibers offer superior absorption compared to synthetic fibers.

[0041] According to the invention, the nonwoven material can be provided on a roll and / or bale in such a way that at least two cutting patterns with corresponding blanks can be processed in parallel. Such a blank Z is in Fig. 2 and Fig. 4 shown. Corresponding patterns are included in Fig. 3As illustrated. For example, the nonwoven material can be supplied by the manufacturer on a roll, bale, or similar. By processing several patterns simultaneously, the number of bandage components produced increases significantly without any increase in costs.

[0042] The in Fig. 3 The schematic patterns shown, as described above, have a calf or lower leg shape. However, the illustrated patterns are only examples and other shapes can be provided, in particular with differently shaped cutting edge sections A1, A1', A2, A2', A3, A3'.

[0043] It is also possible that the bandage part 10 may be made from at least one cut Z of a stretch material.

[0044] The stretch material can have an elasticity of at least 50% and a recovery capacity of 30% to 100%.

[0045] Recovery describes the extent to which a material returns to its original shape after being stretched. The term "extensibility" here corresponds to the English term "stretch." A material is of interest if it is both stretchable and partially resilient. For the use of the bandage 100 as a disposable product, full recovery, i.e., perfectly elastic behavior, is not necessary. The material does not need to completely return to its original shape after stretching, but can remain in a stretched form after an initial contraction. Thus, the recovery can be less than 100%, with 100% representing perfectly elastic behavior. According to the invention, a recovery of 100% to 30%, or 100% to 50%, or 100% to 70% is preferred. Extensibility corresponds to the ability to withstand stretching without damage such as tearing.The higher the elasticity, the more the material can be stretched as a percentage.

[0046] The stretch material can be a 2-way stretch fabric, with one stretch direction extending in the transverse direction QR of the bandage 100, i.e., in only one direction QR. The transverse direction QR is perpendicular to the longitudinal direction L or runs perpendicular to the cut edge section A2, and runs parallel to the cut edge section of the upper and lower cuff area at the knee or ankle when applied.

[0047] It is also possible to use a 4-way stretch fabric, where one stretch direction extends transversely (QR) and another longitudinally (LR) of the bandage 100. Depending on the requirements of the bandage 100, either a 2-way stretch fabric or a 4-way stretch fabric can be used. However, using a 2-way stretch or single-stretch material, whose stretch direction extends only transversely (QR), is cheaper to produce and has only minor disadvantages compared to a 4-way stretch material.

[0048] The in Fig. 2 The cut pieces Z shown, and the bandage components 10 produced from them, are designed for one leg area. Bandage components 10 with different dimensions are schematically illustrated. The lower illustration shows the bandage component 10 obtained from cut piece Z, along with the sock S. The respective compression zones K1 and K2 are highlighted by the shaded areas.

[0049] As mentioned above, the stretch material can comprise elastomer or elastane threads of varying thicknesses, creating different compression strengths in the respective compression zones K1 and K2. Furthermore, the stretch material can comprise elastomer threads with varying pretension, also creating different compression strengths in the respective compression zones K1 and K2.

[0050] Elastane fibers or elastane threads are synthetic filament yarns (yarn count 11-2600 dtex) and consist of at least 85% by weight of segmented polyurethane. They are characterized by their particularly high elastic elongation. Under tensile stress, they can be stretched to 6-8 times their original length and immediately and completely return to their original length after the tension is released. Elastane fibers are easily dyed, oxidation-resistant, and more lightfast, and can be produced in significantly thinner versions than rubber threads, allowing for the production of finer and lighter woven and knitted fabrics. Common manufacturing methods include dry spinning (80% of global capacity), wet spinning, and reactive spinning.They are resistant to perspiration and cosmetic oils with proper care, easily washable, possess moderate abrasion resistance, a density of 1.15 g / cm³; a moisture absorption of 1.0–1.3%; a melting point of approximately 250 °C; a softening point of 175 °C; above 150 °C they yellow and degrade. The maximum tensile strength relative to the initial fineness is 4.5 cN / tex–12 cN / tex, the maximum tensile elongation is 420%–800%, the residual elongation after 300% elongation is 10%–30%, and the bonding temperature is above 170 °C. Brand names for elastomeric or elastane threads include Lycra (Invista), Dorlastan (Asahi), Creora (Hyosung), and Linel (Fillatice). Although the use of elastane threads is particularly preferred, other elastomeric threads with comparable properties can of course also be used. The elastic modulus of elastane threads can range between 0.01 GPa and 0.1 GPa.The elastic modulus of the dressing material is understood to be a local elastic modulus with respect to the transverse direction QR, which is generated locally (i.e. within an area or zone K1, K2 in the longitudinal direction L) in the carrier material by elastomeric threads introduced into the carrier material such as nonwoven fabric.

[0051] For example, a thread thickness in the first compression zone K1 can be in a range of 500 dtex to 1000 dtex, or in a range of 500 dtex to 900 dtex, or in a range of 500 dtex to 800 dtex, or in a range of 500 to 700 dtex, or in a range of 500 to 600 dtex, or in a range of 600 dtex to 800 dtex. In the second compression zone K2, the yarn thickness can be in the range of 100 dtex to 200 dtex, or in the range of 100 dtex to 300 dtex, or in the range of 100 dtex to 400 dtex, or in the range of 100 dtex to 500 dtex, or in the range of 100 dtex to 600 dtex, or in the range of 300 dtex to 600 dtex. Furthermore, the yarn spacing in the first compression zone can be in the range of 0.5 mm to 1 mm, or in the range of 0.1 mm to 10 mm, or in a range of 0.5 mm to 8 mm, or in a range of 1 mm to 7 mm, or in a range of 1 mm to 6 mm, or in a range of 1 mm to 5 mm, or in a range of 1 mm to 4 mm, or in a range of 1 mm to 3 mm, or in a range of 1 mm to 2 mm. In the second compression zone K2, this can be in a range of 4 mm to 4.5 mm, or in a range of 3 mm to 5 mm, or in a range of 3 mm to 5.5 mm, or in a range of 2 mm to 6 mm, or in a range of 1 mm to 15 mm, or in a range of 2 mm to 12 mm, or in a range of 3 mm to 10 mm, or in a range of 4 mm to 8 mm, or in a range of 5 mm to 8 mm, or in a range of 6 mm to 8 mm. However, this is only an example and other thread thicknesses and spacings are possible.Furthermore, the threads can have a thread tension greater than 50%, or greater than 100%, or greater than 150%, or greater than 200%, or greater than 250%, or greater than 300%, or greater than 350%, or greater than 400%, or greater than 450%, or greater than 500% and / or less than 600%.

[0052] As from Fig. 1A As can be seen, the bandage part 10, in addition to the slit area B1, can include the tubular, closed distal area B2, which, when the bandage 100 is applied, is pulled over a foot or hand of the living being and, in the applied state of the bandage 100, is adjacent to the foot or hand. The distal area B2 is in Fig. 1A also simplified by a corresponding arrow.

[0053] The closed section B2 allows the bandage 100 to be applied easily and conveniently and closed using the corresponding fastening elements 22, 22'. The closed section is first positioned at a suitable location (not a wound), for example, on an ankle or wrist. Then, the loosely slit part or flap of the slit section B1 of the bandage part 10 can be easily and releasably closed using the fastening elements 22, 22'. This further simplifies the application of the bandage 100.

[0054] The bandage section 10, when applied, can compressively enclose the ankle area of ​​a foot in its tubular, closed distal section B2 and the calf area of ​​a lower leg in its slit section B1. For example, the bandage 100 can function as a biocompatible physical dressing layer that protects and supports the skin of a living being.

[0055] As described above, the closure part 20 can comprise closure elements 22, 22' individual hook and loop fastener parts punched out from a hook and loop fastener strip, which are individually connected to the bandage part 10.

[0056] In a further embodiment, the closure part 20 can also be designed as a one-piece multi-hook closure part, which is connected on one side in its non-hook area to the bandage part 10 and has protruding closure elements 22, 22' on its opposite side in its hook area, which are formed by punching the hook closure tape.

[0057] The releasable closure elements 22, 22' allow the dressing 100 to be opened as needed, for example to monitor the healing process of a wound or to easily replace a wound dressing, such as a plaster or pad. This eliminates the need for unnecessary wrapping as with conventional dressings.

[0058] The closure elements 22, 22' described above can have hook closure elements or adhesive tape closure elements (for example with a release liner) instead of or in addition to the hook and loop closure elements described above.

[0059] One such multi-purpose Velcro fastener is, for example, in Fig. 4 shown, with the punching out of the closure elements 22 being simplified. In Fig. 4 Two superimposed cut pieces Z are shown, which are taken from a non-woven material or stretch material and then processed step by step.

[0060] According to a method for manufacturing the dressing 100, the nonwoven material or the stretch material can be provided on a roll and / or bale as described above, wherein two sections of the nonwoven material or the stretch material are cut according to a predetermined pattern, as described in the Fig. 3As described, the sections can be removed. The removal of the sections from the nonwoven material or the stretch material can be done by cutting or punching. The resulting uniform cut pieces Z can be joined together at corresponding end areas by ultrasonic welding. For example, the cut pieces Z can be joined together by means of a seam that is elastic in the seam direction N. The seam direction N is in Fig. 1A, 1B , 1F and Fig. 3 illustrated as a dotted line.

[0061] The cut pieces Z can then be further processed, whereby in a subsequent processing step nonwoven material or stretch material is left out at the end areas. For example, at a Fig. 4On the upper side of the blank Z shown, instead of the recessed material, a material associated with the closure part 20 is connected to the blank Z. The closure elements 22 can then be punched out from this to form the bandage part 10.

[0062] In another embodiment, a blank Z can also be removed and processed in one piece. For example, the closure part 20 can be attached to one side end. The bandage part 100 can then be formed by folding the blank Z. Here, the slotted area B1 extends along the entire longitudinal direction LR. A resulting fold line extends longitudinally LR on the side opposite the closure part 20. In this case, however, this side is not curved and adapted to a calf shape, but is ideally straight to ensure easy folding.

[0063] As with reference to Fig. 3As described, the bandage component 10 can have a shape adapted to the calf area of ​​a lower leg. This allows the bandage 100 to provide an optimal fit from the outset. Other shapes are possible. Similarly, the footie or sock S of the further embodiment can also provide a shape adapted to a foot.

[0064] As already described, the bandage can be designed as a hygienic disposable product.

[0065] The inventive bandage 100 provides an adaptable, ready-to-use lower leg bandage (for single use) that covers the lower leg from the ankle to below the knee. One purpose of the inventive bandage 100 is to act as a biocompatible physical layer to protect and support the skin. The bandage 100 is intended to be used alone or in conjunction with other products for medical treatment. When applied to injured skin, it serves as a secondary or tertiary dressing layer around the lower leg. The bandage 100 has cushioning properties, can contribute to the protection of underlying layers (e.g., wound dressings), and can absorb excess fluid to a limited extent. The bandage 100 is a non-sterile, inactive, non-invasive product.

[0066] The bandage 100 according to the invention is also suitable for use under compression and can be easily combined with a ready-to-use foot bandage.

[0067] For example, the bandage 100 can be used on patients who are receiving short- or long-term medical treatment of the lower leg, or who are bedridden or have limited mobility.

[0068] The following is an application example of the inventive bandage 100 for the right or left lower leg.

[0069] First, select the correct size 100 bandage using a size chart. When selecting the size, please consider the following points: The thickness of the wound dressing must be taken into account. Changes in lower leg circumference due to swelling (edema) are also possible throughout the day. During the healing process or if the type of treatment changes, a different product size may be necessary. Any existing wounds must be properly treated before application. Carefully pre-stretch the lower band of the 100 bandage (holding it at the seams to prevent tearing). The 100 bandage must be applied so that the opening with the hook-and-loop fasteners faces forward. Carefully pull the lower band over the foot and up to the ankle. Grasp the flaps of the opening close to the seam. If necessary, the bandage can be spread open from the inside by hand to reduce friction on the foot.The fasteners should be pre-attached in sequence, working from the bottom up. Ensure that the two sides of the opening overlap sufficiently. Then readjust the fasteners. The bandage 100 should lie flat and without wrinkles. Remove and dispose of after use. The hook-and-loop fasteners should also be readjusted (loosened / widened) if (a) there is a feeling of constriction, (b) the bandage 100 loses its elasticity in one area or is stretched too tightly, (c) the bandage 100 slips. Use of the bandage 100 as a primary layer: On intact, unbroken skin. Use of the bandage 100 as a secondary layer: On injured skin or open wounds with an underlying primary layer (wound dressing).
