Description

  The present invention relates to compression devices, specifically the treatment and / or management of limb edema and other venous and lymphatic disorders, more specifically limb ulcers and limb lymphedema. The present invention relates to a compression device for applying compression to a part of a user's limb.

  Compression therapy is generally prescribed to support the insufficient venous or lymphatic system that returns blood or lymph to the heart. Thus, compression is generally regarded as a standard treatment for use in the treatment of edema and other venous and lymphatic disorders, such as lower limb venous ulcers and lymphedema. The positive effect of compression treatment on venous lymphatic reflux and healing of chronic venous (lower limb) ulcers is well documented in medical literature.

  Compression bandages and stockings are the most common compression systems used for compression treatment. However, compression stockings generally do not provide the desired therapeutic compression pressure because they typically need to be very elastic to allow attachment and detachment. A compression bandage is made of a material with much lower elastic (or in some cases nearly inelastic) properties, and is typically much more than a compression stocking to support a muscle pump that circulates venous blood to the heart. And thus much more effective in compression therapy. However, compression bandages typically need to be applied by well-trained professionals to achieve the desired and / or required pressure profile, and such bandages typically (e.g., for reducing edema). The resulting limb volume change (eg, a decrease) requires frequent reapplication.

  Many other compression systems have been proposed. Many of these can generally be described as including a fabric that wraps around the limb and a closure mechanism for securing the fabric around the limb (see, eg, US Pat. No. 3,538,194, ibid.). 3,856,008, 3,845,769, 5,653,244, International Patent WO 01/72250, US 2002/0062096, 2003/195449, 2005/0192524, International Patent WO 2006/048619). A large number of non-bandage and non-stocking type compression systems have been proposed, but only a few have been commercialized. And products available on the market. In particular, these commercial products offered as an alternative to typical compression bandage systems include a plurality of band-like elements for wrapping and covering (eg, overlapping and / or cross-wrapping / covering). .

  Easy to use and apply, preferably applicable to untrained personnel or even patients, at the same time whether the desired and / or required appropriate fit is achieved and / or maintained There is a continuing need for non-bandage and non-stocking type compression devices that promotes recognition and thereby facilitates the provision of desirable compression uniformity.

In one aspect of the invention, a compression device is provided for applying compression to a user's limb, which includes a sleeve for substantially covering a portion of the user's limb, the sleeve comprising an outer The sleeve has a surface, an upper edge, a lower edge, and two side edges, and in a transverse direction from the first side edge to the second side edge, the sleeve has a first side area, a central area, and a second side edge. Having a side region, the second side region of the sleeve comprising a series of a plurality of rings between the upper and lower edges of the sleeve, each ring being a substantial portion of the sleeve. Removably or fixedly attached by a strap extending between the sleeve and the ring in a transverse direction, at least a portion of the strap being extensible at least in the transverse direction, the extensible portion being , At least how to cross the sleeve When the stretchable portion is in an unstretched state, the outer raised material loop is on the outer surface and in use is tensioned in the transverse direction of the sleeve When the extensible portion extends and extends in the transverse direction and the loop is flattened,

Extending in a direction, the distal end portion is disposed oppositely from the central portion of the sleeve, and each tab is a first major surface disposed toward the outer surface of the sleeve, and the sleeve A second major surface disposed oppositely from the outer surface of the tab, wherein the second major surface at the distal end portion of the tab includes a portion of a mechanical fastening system and The second major surface at the proximal end portion of the tab is the mechanical fastener A complementary portion of the stem, wherein the tab and the ring are in use, the tab passes through the ring and folds, and the first side edge of the sleeve is pulled toward the ring and fastened Thus, the sleeve is constructed and arranged to be clamped and restrained around the limb of the user.

In another aspect of the invention, a compression device is provided for applying compression to a user's limb, which includes a sleeve for substantially covering a portion of the user's limb, the sleeve The sleeve has an outer surface, an upper edge, a lower edge, and two side edges, and in the transverse direction from the first side edge to the second side edge, the sleeve has a first side area, a central area, and a second side edge. The second side region of the sleeve includes a series of eyelets or a plurality of rings between the upper edge and the lower edge of the sleeve, the sleeve comprising: An elongate stretchable fold extending substantially longitudinally between the upper edge and the lower edge of the sleeve, the fold fold extending at least in a transverse direction of the sleeve The extensible scissor fold comprises at least a transversely elastic material And when the extensible scissor fold is in an unstretched state, an outwardly raised loop of material is on the outer surface, and when in use, the stretchable fold is stretchable in a transverse direction of the sleeve The fold-fold extends and extends in the transverse direction and is configured and arranged so that the loop is flat;
The device further includes a plurality of strip-shaped mechanical fastening tabs, each eyelet or ring (if applicable) being provided with a single tab, each tab connected by a proximal end portion and an inner tab portion. The proximal end portion is removably or fixedly attached to the first side region of the sleeve so that the tab can be an eyelet or a ring (if applicable) ) And extending in a substantially transverse direction of the sleeve, the distal end portion being disposed oppositely from the central portion of the sleeve, and each tab being disposed on the sleeve The second main surface at the distal end portion of the tab having a first main surface disposed toward the outer surface and a second main surface disposed opposite the outer surface of the sleeve. The surface includes a portion of a mechanical fastening system and the tab The second major surface at the proximal end portion includes a complementary portion of the mechanical fastening system, and the tab and the eyelet or ring (if applicable) Passing through the ring (if applicable) and turning back, the first side edge of the sleeve is pulled and fastened towards the eyelet or ring (if applicable) so that the sleeve Constructed and arranged to be clamped and restrained around the limb.

  For clarity, it will be appreciated that after the compression device is applied to the user's limb, the transverse direction of the sleeve is also circumferential. In accordance with ASTM D 4848-98 (2012) and BS EN 14704-1: 2005, elasticity is a material that provides a tendency to regain its original dimensions and shape immediately after the deforming force is removed. It is a characteristic.

  Surprisingly, a sleeve-like fabric product that is opened and closed by a releasable mechanical fastening system including a fastening tab comprises an extensible part of a strap or an extensible folding fold comprising a material that is elastic at least in the transverse direction. Provided with respective complementary portions of a mechanical fastening system associated with opposing rings or eyelets when the extensible strap portions or fold folds are each in an unstretched state (eg, the compression device is not in use) Sometimes, when there is a loop of outwardly raised material on the outer surface and the strap is stretched in tension in the transverse direction of the sleeve, the stretchable portion or the fold-fold portion of the strap, respectively, stretches in the transverse direction. And is simple to use and apply by constructing and arranging the loop to be flat (eventually disappear), and It has been found that it is possible to provide a compression device that advantageously provides a visual indicator that facilitates assessment of the degree of stretch for the person applying the device and that provides a good anatomical fit. Has been. Furthermore, when the stretchable part or fold of the strap is not stretched or only partially stretched, the outwardly facing loop is fully raised or only partially flat. So that it can be seen and when the extensible part of the strap or the fold fold is fully extended, this outwardly facing loop disappears (ie the material loop is outside) To the extent that it no longer rises). Such visual indicators are advantageous when applied. This is because once the loop is completely flat (and thus disappears), it is fully stretched and thus an indication of a sufficient anatomical fit. Further, a plurality of ring straps provided side by side between the upper and lower edges of the sleeve, or an elongate that extends substantially longitudinally between the upper and lower edges of the sleeve. By providing such a loop indicator configuration for the stretchable folds, it is possible to have a visual indicator for the degree of extension, and thus the respective height of the sleeve between the upper and lower edges. Fit, so that, if desired and / or necessary, the degree of tightening of the individual fastening tabs passed through the opposing rings or eyelets is relative to above the limb portion of the user covered by the sleeve Adjustments can be made to facilitate the provision of the desired anatomical fit and thereby promote uniform compression. This loop index configuration is also preferably useful when the user is wearing a compression device. For example, as desired, if the volume of the limb is reduced, for example as a result of reduced edema due to effective compression treatment, the degree of tension in the device and the degree of tension in the extensible part of the strap or in the fold-fold The loop that has been lowered and flattened is visibly outwardly crumpled, forming a fully raised or somewhat flat loop (depending on the degree of reduced tension), thereby An indication is provided that the device should be retightened or reapplied.

  Desirably, the extensible part of the strap or the fold (if applicable) comprises two layers, an outer layer (facing outward) material and an inner layer (facing inward) material, the inner layer The product of the modulus of elasticity of the material and the thickness of the inner layer is less than the product of the modulus of elasticity of the outer layer material and the thickness of the outer layer, the outer layer material being a loop material, and the inner layer Material is secured to the outer layer material, thereby providing a loop of the outer layer material above the inner layer when the extensible portion or fold-fold of the strap is each in an unstretched state, Can be flat when tensioned in use, whereby the extensible portion or folds of the strap are each stretched transversely. In the loop index configuration, the product of the elastic modulus of the inner layer material and the thickness of the inner layer material is at least 1/2 or less than the product of the elastic modulus of the outer layer material and the thickness of the outer layer. It has been found that it is desirable, in particular, to be at least ¼ or less, so that a transition from an apparent loop to a completely flat loop does not require a very long stretch. Preferably, at least one of the outer layer material and the inner layer material is elastic at least in the transverse direction, and more preferably each of these materials is elastic at least in the transverse direction.

  The modulus of elasticity (also referred to as the modulus of elasticity) can be measured according to ASTM D 882-09 “Standard Test Method for Tensile Procedure of Thin Plastic Sheeting”. It should be noted that although this standard method covers the measurement of the tensile properties of thin sheet plastics, the described test method and measurement of elastic modulus are described herein. It has been found that it can be suitably used in connection with materials suitable for the compression device described in.

  The sleeve, in particular at least the central region of the sleeve, preferably comprises a material suitable for use in applying compression, more preferably, at least the central region of the sleeve is elastic and measured, for example according to DIN 61632: 2009 And includes a material having a maximum elongation of more than 0% and a maximum of 60% in at least the transverse direction of the sleeve under a load of 10 N per cm width. Such materials are referred to herein as “short stretchable materials”. Referring to the textbook "Foldi's Textbook of Lymology" 2nd edition, the compression bandage stretchability, in other words, elasticity is short stretch (up to 60% under a load of 10N / cm, ie 0% Super, those having maximum elongation of 60% at maximum), medium stretchability (60-140%), and long stretchability (above 140%). Therefore, non-stretch bandages have no stretch amount ( That is, 0%).

  To further enhance the index effect of the loop index configuration and / or further facilitate the provision of uniform compression, the elastic modulus of the loop material (e.g., the extensible portion of the two-layer strap / outer layer material of the folded embodiment) And the thickness of the loop material is preferably at least 90% of the product of the elastic modulus of the short stretch material and the thickness of the short stretch material, in particular the loop material (e.g. stretchable of a two-layer strap) The product of the modulus of elasticity of the partial layer / outer layer material of the folded embodiment) and the thickness of the loop material is greater than or equal to the product of the modulus of elasticity of such a short stretch material and the thickness of the short stretch material.

  For ease of viewing the loop index configuration, the strap or foldable stretchable portion preferably has a width in the transverse direction of the sleeve of at least 0.1 cm, specifically 0.5 cm when unstretched. To facilitate the sleeve construction, for example with respect to component dimensions and material usage, preferably the strap or foldable stretchable portion has a maximum width of 4 cm in the transverse direction of the sleeve when unstretched. The maximum is 3 cm.

  Preferably, particularly with respect to facilitating viewing the loop change and flattening, the strap or the foldable stretchable portion has a width relative to the transverse direction of the sleeve when the loop is in the flattened stretched state. Is at least 1 cm. In order to facilitate viewing and / or to facilitate cross / circumferential compression uniformity, the strap or the foldable stretchable portion is preferably sleeved when the loop is in a flattened stretched state. The maximum width in the transverse direction is 8 cm, specifically 6 cm.

  To further emphasize the index effect of the extensible strap portion or the fold-fold in the two-layer extensible strap portion / fold-fold embodiment, the inner layer material and the outer layer material are the stretchable portion / fold-fold of the strap. Provides a loop of at least one outer layer material above the inner layer when the is in an unstretched state, which is tensioned during use, thereby allowing the stretchable portion / folding of the strap to be transverse When stretched, it can flatten and, in addition, provides an area of at least one outer layer material above the inner layer, the outer layer material being against the upper and lower edges of the sleeve. Includes a slit (eg, an opening) that extends substantially longitudinally (hereinafter referred to as a “slit region”), whereby the stretchable / folded strap portion is unstretched. When in the state, the outer layer material in the at least one slit region is substantially flat and the side edges of the slit approach or overlap each other while being tensioned during use thereby When the stretchable portion / folder of the slit is stretched in the transverse direction, the side edges of the slit can be spaced apart to be preferably configured and arranged to expose the underlying inner layer. This slit area acts like a window or eye and is “closed” when the strap's extensible / folded fold is unstretched and covers the underlying inner layer, and the strap's extensible / folded fold "Opens" when is stretched in the transverse direction, thereby providing a second indication for proper stretching and tension of the sleeve. This indicator effect is also an indication that the inner layer (especially at least its upper surface) becomes visible when the edges of the slit are separated and / or a color different from the outer layer color, in particular the outer layer slit. It can be enhanced by providing an indicator with a color different from the color of the region. Desirably, the at least one outer layer material loop and the at least one slit region are provided longitudinally along the upper and lower edges of the sleeve, and more desirably, at least two outer layers. A material loop is provided, wherein the at least two outer layer material loops and the at least one slit region are provided alternately along the length of the upper and lower edges of the sleeve.

  With respect to the first aspect (ie, an embodiment including an extensible portion of the strap), providing an indication and provision of a preferred anatomical fit to the user's limb (eg, the lower leg including the calf) that is covered by the sleeve during use. To further facilitate, preferably a plurality of rings or straps (each including a gap between the rings or straps) extend over a height corresponding to at least 70% of the height from the upper edge to the lower edge of the sleeve. Exists. In general, the plurality of rings or straps (including the gaps between the rings or straps, respectively) correspond to 70% to 100% and in some cases more than 100% of the height from the upper edge to the lower edge of the sleeve. Extending over height.

It can be in the range of ~ 2 cm.

  With respect to the second aspect (ie, the embodiment including the fold-folded portion), it further facilitates the indication and provision of a favorable anatomical fit to the user's limb (eg, the lower leg including the calf) that is covered by the sleeve during use. For this purpose, preferably the folds extend over a height corresponding to 70% to 100% of the height from the upper edge to the lower edge of the sleeve. To further facilitate the provision of a preferred anatomical fit, a plurality of eyelets or rings (if applicable) (including gaps between each eyelet or ring) are provided at a height from the upper edge to the lower edge of the sleeve. It is desirable to extend over a height corresponding to at least 70%.

  In the following description, unless explicitly stated otherwise, terms such as “upper”, “lower”, “upper”, and “lower” refer only to the features shown in the figure and limit the direction of use etc. Not intended. Not all figures are drawn to the same scale.

  It is to be understood that the present invention covers all combinations of the unique, preferred, desirable, advantageous, advantageous and preferred aspects of the present invention described herein.

  FIG. 1 shows an outer plan view of an exemplary embodiment of a compression device (100) for use in applying compression to a user's limb, and FIG. 2 is an illustration of this exemplary embodiment. A cross-sectional view is shown. The device includes a sleeve (1) for substantially covering a portion of the user's limb. The sleeve includes an outer surface (3), an inner surface (4), an upper edge (7) and a lower edge (8). When the device is being used against the limb, typically the inner surface (4) is oriented towards the wearer / user (in the following, the term "inner" typically refers to the wearer / user The term "outside" refers to the one facing away from the wearer / user), the upper edge is facing the user's torso and the lower edge The edge is the side away from the user's torso, and both the upper and lower edges are essentially transverse and are placed essentially circumferentially around the limb after wearing. As can be seen from FIG. 1, the sleeve includes two side edges (9, 10) extending from the upper edge to the lower edge. In the transverse direction from the first side edge (9) to the second side edge (10), the sleeve has a first side area (13), a central area (14) and a second side area (15). Including. The second side region of the sleeve includes a plurality of rows of rings (16) between the upper and lower edges of the sleeve. Each ring is attached between the sleeves, in particular between the second side region and the ring, by a strap (17) extending in a substantially transverse direction of the sleeve, this particular representative In the embodiment, it is fixedly attached. As described above, it will be appreciated that after the compression device is applied to the user's limb, the transverse direction of the sleeve is also circumferential. Referring to the cross-sectional view of FIG. 2, the strap (17) is attached to the second side region (15) of the sleeve (1), specifically the outer surface (3) of the sleeve in the second side region. It can be seen that is attached to. In this exemplary embodiment, the strap is fixedly attached, but in other embodiments (such as those shown illustratively in FIGS. 4 and 5), the strap is removably attached. It will be understood that this can be done.

  The strap includes an extensible portion of the strap, which includes at least a transversely elastic material, such as when the extensible portion of the strap is in an unstretched state (eg, when the compression device is not in use). The loop of material bulges outward on the outer surface, and when used under tension in the transverse direction of the sleeve, the extensible portion of this strap stretches in the transverse direction and the loop becomes flat ( It will be constructed and arranged so that it will eventually disappear.

  Returning to the exemplary embodiment shown in FIGS. 1 and 2, each strap (17) may include an extensible portion (21), which comprises a loop (20) that projects outwardly outward. Configured. As can be seen in the cross-sectional view of FIG. 2, this shows the stretchable portion of the strap in an unstretched state, similar to FIG. The stretchable portion of the strap also preferably includes two layers, an outer layer material (18) and an inner layer material (19), where the inner layer material is a loop of outer layer material (ie, loop (20)). It can also be seen from the figure that it is secured to the outer layer material as provided above the inner layer. At least one (preferably both) of the inner layer material and the outer layer material has elasticity in at least the transverse direction. As a result of the properties of the inner layer material and / or outer layer material, the configuration of attaching the inner layer material and the outer layer material to each other, and the configuration of attaching the strap to the ring and sleeve, the loop containing portion (21) of the strap is at least It is extensible in the transverse direction. When the stretchable portion of the strap is not stretched, i.e., in an unstretched state, the loop (20) appears as an elongated bulge or hump, as shown in FIGS. In use, if the device is applied to the user's limb, tension is applied, which causes the stretchable portion (21) of the strap to extend in the transverse direction, and the loop can and is flattened. .

  In embodiments where the stretchable portion of the strap includes two layers as described above, preferably the product of the inner layer material's (transverse) modulus and the inner layer material's thickness is the outer layer material's (transverse Smaller than the product of the elastic modulus (in the direction) and the thickness of the outer layer material. More preferably, the product of the modulus of elasticity of the inner layer material and the thickness of the inner layer material is at least one half or less of the product of the modulus of elasticity of the outer layer material and the thickness of the outer layer material, more preferably at least 1 / 4 or less.

  In the exemplary embodiment of FIGS. 1 and 2, when the stretchable portion of the strap is in an unstretched state, the ring is opposite the second side edge portion and along the second side edge of the sleeve; And it arrange | positions away from here. Specifically, the side edge of each ring on the side close to the second side edge of the sleeve is arranged at a distance of up to 4 cm from the second side edge, specifically, a distance of up to 3 cm. Is done. Alternatively, when the extensible portion of the strap is in an unstretched state, the ring may be placed directly adjacent to the second side edge, specifically the side edge near the second side edge of the sleeve. Can be placed directly adjacent to the second side edge of the sleeve.

  The sleeve may be substantially rectangular, trapezoidal, or irregularly shaped when flattened as shown in FIG. For example, the sleeve in many exemplary embodiments shown herein (eg, FIG. 1) is substantially trapezoidal. To facilitate an optimal fit to the user's limb site, the upper and / or lower edge of the sleeve may preferably be slightly curved, in particular the upper edge may be slightly convex. And / or the lower edge (usually located on the side away from the user's torso) may be slightly concave or convex. Alternatively or in addition, one or both of the side edges may be slightly curved, and in particular may be slightly convex. Thereby, the fitting with respect to the developed calf part may be promoted. In use, when the compression device is applied to the user's limb, preferably the sleeve is substantially cylindrical, barrel, or frustoconical.

  The compression device further includes a plurality of strip-shaped mechanical fastening tabs (2). One tab is provided for each ring (16). Each tab includes a proximal end portion (22) and a distal end portion (24) connected by an inner tab portion (23). In the exemplary embodiment shown in FIGS. 1 and 2, and other exemplary embodiments described herein, the proximal end portion (22) is the first side region ( 13) is detachably attached. It will be appreciated that this proximal end portion may alternatively be fixedly attached (eg, by adhesive, bonding, or stitching) to the first side region of the sleeve. The fastening tab (2) has tabs disposed on opposite sides of the ring, with the distal end portion (24) disposed away from the central portion of the sleeve, and each tab is substantially transverse to the sleeve. It is attached to the sleeve so as to extend. According to FIG. 2, each tab has a first main surface (ie, inner surface (34)) disposed toward the outer surface (3) of the sleeve and a second main surface disposed on the side away from the outer surface of the sleeve. It can be seen that it has a surface (ie, outer surface (33)). The second major surface (33) of the distal end portion (24) of the tab includes a portion (25) of the mechanical fastening system, and this second major surface of the proximal end portion of the tab is of the mechanical fastening system. Complementary portion (26) is included. As seen in the exemplary embodiment of FIGS. 1 and 2, and other exemplary embodiments described herein, the second major surface of the inner tab portion of the fastening tab is also a mechanical fastening system. Of the complementary portion (26).

  Generally, the fastening tab has a second major surface of the distal end portion of the fastening tab comprising a hook, stem, and / or cup-type fastener (first tab fastener), the proximal end portion of the fastening tab. The second major surface has or is provided with a structure adapted to engage these first tab fasteners. The second major surface of the inner portion of the fastening tab may further have or comprise a structure adapted to engage the first tab fastener.

  As mentioned above, the fastening tab can be detachably or fixedly attached to the sleeve. Preferably, the fastening tab is attached so as to extend across the first side edge. Specifically, this tab generally extends at least 2 cm outward from the first side edge. For those embodiments in which the fastening tab is removably attached, preferably the first major surface of the proximal end portion of the fastening tab is a hook, stem, and / or cup-type fastener (second tab fastener). ) And the outer surface of the first side region of the sleeve has or is provided with a structure adapted to engage these second tab fasteners. Here, the first major surface of the proximal end portion of the fastening tab can be removably attached to the outer surface of the first side region of the sleeve. The second tab fastener may be the same as or different from the first tab fastener. Where the second tab fastener and the first tab fastener are different, preferably the outer surface of the first side region of the sleeve is adapted to engage both the first and second fasteners. It has or has a structure. Preferably, the second tab fastener and its complementary engagement structure are selected to provide a stronger fastening than the first tab fastener and its complementary engagement structure. The use of a detachably attached fastening tab can be particularly useful because it allows to provide a compression device with adjustable width.

  The compression devices described herein, in particular their sleeves, are available in a variety of sizes to accommodate limb size differences (eg, arm and leg differences) and general differences in the size of a particular limb. Can be offered at. The compression device described herein is particularly suitable for use on the lower leg, including the calf. With regard to the latter, for example, considering the dimensions of the adult human lower leg, including patients with lymphopenia, this size can range from about 130-420 mm around the ankle and 280-650 mm at the thickest point, for example 7 It is possible to provide a compression device in a standard (thickness) size, for example XS, S, M, L, XL, XXL, XXXL, which is 80 % And the remaining 20% can be covered by special order. In addition, given the length of the lower leg of an adult human, this size can range from about 20 cm to 40 cm, which can be provided in relation to the standard (thickness) sizes described above, For example, it can be provided in three length sizes, short, standard and long, which can also cover 80% of the potential length of potential users. With regard to the standard thickness size, the number of standard sizes that cover 80% of the potential size of a potential user's perceived part is determined by the user or caregiver, for example, when applying a compression device to the user's limb. This can be reduced by providing a compression device configured to easily adjust the thickness of the sleeve. In particular, as described herein, the fastening tab is configured to be removably attachable to the first side region of the sleeve and configured so that the first side region of the sleeve is trimmable. It may be advantageous to provide a compression device.

  Returning to the exemplary embodiment shown in FIGS. 1 and 2, the second major surface (outer surface) (33) of the distal end portion (24) of each fastening tab (2) is a hook, stem. And / or a cup-shaped fastener (25), wherein the proximal end portion (22) of the fastening tab and the second major surface (outer surface) of the inner tab portion (22) are such that these tab fasteners are It has or comprises a structure (26) adapted to engage. In addition, the first major surface (inner surface) (34) of the proximal end portion (22) of each fastening tab (2) is provided with a hook, stem and / or cup-shaped fastener (27). (These second tab fasteners may be the same as or different from the first tab fastener (25)), the outer surface (3) of the first side region (13) of the sleeve (1). Has or comprises a structure (28) adapted to engage the second tab fastener (27).
