The invention concerns a compression garment for a limb of a person, comprising a flexible body portion having a first, limbward side and a second side opposing the first side, and at least one band extending from a lateral side of the body portion for wrapping around the limb, wherein the band comprises a fastener such that the end of the band is removably attachable onto the compression garment when wrapped around the limb. The invention further concerns a method for donning such a compression garment.
Compression garments for limbs of a person are generally known in the state of the art. Such compression garments have multiple applications, for example therapeutical applications, prophylactic applications and the like. They are also used to improve the general well-being of healthy persons. Compression garments usually comprise a body portion for at least partly wrapping around a limb and one or more bands for wrapping around the limb, in particular together with the body portion, for fastening the compression garment to the limb. Compression exerted onto the limb may, for example, be adjusted using the one or more bands.
However, an effect of the compression garment, be it a therapeutical effect or simply an improvement of the general well-being of a healthy person, sometimes depends on the correct use and placement of the bands. Since bands are usually elongate structures having a length which may even exceed the circumference of the limb, correct manual placement of the bands may be complicated, in particular leading to oblique positioning and/or confusion regarding fastening positions for the bands.
Regarding applications of compression garments, massage, acupressure, and reflexology treatments are well-accepted examples of a pressure treatment, which may be used for therapy as well as the improvement of the general well-being of healthy persons. For example, these treatments may be applied to relieve symptoms such as pain and stress. Usually, such pressure treatments require active physical energy input from a practitioner or are self-administered by the person seeking relief from symptoms or a general improvement of the well-being. Given the strenuous physical exertion required to deliver these treatments, many types of massage devices have been developed to reduce the burden of therapy, or, in general, treatment.
Examples for actively powered pressure treatment devices include massage chairs, leg and foot massagers, vibrators, vibrating pads, inflatable pressure cuffs, and similar devices that require an electrical energy source. Examples for passive pressure treatment devices include rollers, foam mats, support pads, and similar devices that either require the user to continually exert energy to deliver effective pressure or to bear weight on the device to receive counter pressure through gravity.
WO 2017/165678 A1 discloses a compression garment for neurological and circulatory disorders, which includes a body portion and a pad. The body portion may be operable to wrap around a foot and the pad can be attached to an inner surface of the body portion. The pad can include an outward protrusion and/or an inward recess, wherein the pad is applied to exert pressure on the abductor hallucis and flexor hallucis brevis muscles of the foot. That is, this device has in particular been specifically designed to provide pressure to predetermined, concrete anatomical features, in this example in particular for the treatment of the restless leg syndrome. Applying pressure to the abductor hallucis and flexor hallucis brevis muscles on the bottom and medial side of the foot helps alleviate the impulses and urges to move the legs while at rest.
While this exemplary device also uses tensioning bands, it is directed to only the treatment of defined anatomical features of the foot and does not provide adjustability, additionally suffering from the drawbacks regarding usage of bands laid out above.
It is thus an object of the current invention to provide a pressure garment providing improved handling of the bands, in particular regarding accurate placement and comfort, while still providing adjustability and, in particular, also various adjustments regarding the application area and type.
This object is achieved by providing a compression garment according to claim 1. Advantageous embodiments are described in the dependent claims.
In a compression garment for a limb of a person according to the current invention, the compression garment comprising a flexible body portion having a first, limbward side and a second side opposing the first side, and at least one band extending from the lateral side of the body portion for wrapping around the limb, wherein the limb comprises a fastener such that the end of the band is removably attachable onto the compression garment when wrapped around the limb, the body portion further comprises at least one guiding element providing a channel for receiving the band and guiding the band back over itself when the band spans over the first side to provide an opening for receiving the limb.
In particular, using the fastener, the band may be attached onto itself, while, in embodiments, it may also be possible to attach the band to the body portion. Preferably, the band may be optionally attached to one of itself and the body portion. If the band is fastenable on itself, the band may be guided back onto itself using the guiding element.
When the compression garment according to the invention is in use, the band extends from one lateral side of the body portion, in particular a lateral side edge, spans over the first side to the opposing lateral side to create the opening and is guided through the channel back over itself for fastening the end to the outside of the garment, in particular the band itself and/or the body portion. In this context, extending from a lateral side edge means that the band is fastened or fixed to the body portion at or near the lateral side edge.
The invention thus proposes a unique closure system, where the at least one band is fed through a channel to guide the tensioning, direction, and placement of the at least one band. In this manner, for example, the person may pull the band fed through the channel of the guiding element to adjust tension without the risk of displacing the band, in particular misplacing it such that a treatment effect is mitigated or even negated.
The choice of fastening position on the garment, in particular on the band itself, determines pressure exerted by the band and also the body portion, since, after wrapping around the limb/creating the opening for the limb, the band is again guided, using the guiding element, over a defined area of the body portion, providing compression there. Preferably, the channel is provided at the second side of the body portion, as is the guide element.
In a particularly preferred embodiment, the length of the band is dimensioned such that, for a defined limb circumference range, the band, in use, completely circumnavigates the limb and thus the remaining garment including the body portion, such that the tension distribution around the whole compression garment, is improved and, due to guidance through the channel, also locally clearly defined.
In preferred embodiments, the compression garment may be a wrap, which is donned by wrapping the compression garment around the limb. However, the current invention may also be applied to non-wrap garments, like, for example, compression stockings and the like, where accurate placement, uniform distribution of compression and easy handling for bands can be achieved.
The invention is especially advantageously applicable to applications where local pressure treatment is to be applied, for example when using body portions not completely wrapping around the limb for a treatment of arms, legs, hands and/or feet. In particularly preferred embodiments, the body portion may be configured to press a pad or the like onto certain predefined areas of the limb, as further explained below.
It can generally be said that, in particular for a wrap as compression garment, the body portion and the band may together wrap around the limb when in use.
Preferably, the fastener comprises a hook-and-loop fastener. Hook-and-loop fasteners are particularly preferred, since many, in particular textile, materials have been developed and proposed which may be used as a loop portion, to which the hook portion of the fastener may engage. In particular, the bands and/or the body portion may comprise on their outer surface a material comprising loops suitable for engagement with the hook portion of the fastener. In this manner, the hook portion, which is preferably provided at the end of the band, may be attached anywhere onto the band and/or the body portion where the material, in particular the loop material, is present. In preferred embodiments, velour may be used as loop material.
Thus, in preferred embodiments, the body portion and/or the at least one band may comprise a cushioning layer and/or structural layer, in particular a velour layer. Of course, also other types of composite materials for the body portion and/or the bands are conceivable.
Alternatives for using a hook-and-loop fastener in the current invention comprise snap fasteners, magnetic fasteners, latches and the like, but are less preferred.
The at least one band and/or the body portion may be at least partly inelastic and/or at least partly elastic, but are usually both flexible. At least section-wise provided elasticity of the band and/or the body portion, may, in particular be provided to implement a compression measurement system, as will be further described below.
In embodiments, the at least one band and/or the body portion may be trimmable, in particular to customize the garment to a specific limb of a person. For example, the at least one band may be trim mable to be able to shorten the band for smaller circumferences and the like, where it is preferred to have the hook portion of a hook-and-loop fastener removably attachable to the end of the band. Of course, it is also possible to have a trimmable body portion, for example, if the concrete treatment requires smaller areas to be covered, or the like. To facilitate trimming of the at least one band and/or the body portion, indicia may be provided on the at least one band and/or the body portion, for example marking trimming lines for certain circumferences of the limb and/or modes of treatment.
It is generally noted that the guiding element is preferably positioned and/or formed on the second side of the body portion, such that the end of the band extending from the lateral side naturally juts out of the channel on the outer side of its beginning, and not on its limbward side.
In especially preferred embodiments, the guiding element is elongate and/or at least one guiding sleeve, and/or the channel is segmented, wherein the guiding element comprises multiple guiding segments, in particular belt loops. If the guiding element is a guiding sleeve, the guiding sleeve may extend in a longitudinal direction, corresponding to the longitudinal direction of the channel, and may have openings in peripheral directions, in particular having a partial sleeve design with periodically repeated peripheral openings. However, it is also possible to use, for example, equally spaced belt loops which are pointwise or sectionwise defining the channel. In both cases, advantageously, the band is guided over a greater longitudinal extent, thus providing improved and robust guidance on the body portion, in particular the second side of the body portion.
A guiding sleeve, however, may of course also be continuous, that is, without peripheral openings, which is in particular preferred if the guiding sleeve is to be manufactured from a one-piece basic element with the body portion, for example, by folding a section of the basic element over itself to form the channel and thus the guiding element.
Also, generally and preferably, the guiding element and/or the at least one band are formed integrally with the body portion. In particular, the body portion and the band and/or the guiding element can be formed from one piece. Preferably, however, the bands are attached to a one-piece element for the body portion and the guiding element to improve material yield in production. For example, the combined body portion-guiding element piece and the bands may be cut separately from a basic material, whereafter the bands may be sewed to the other piece to obtain a basic element from which the compression garment can be formed.
In preferred embodiments, the guiding element may comprise a folded-over section of the body portion fastened back onto the body portion to form the channel. For example, a one-piece element for forming the body portion and two guiding elements may have double the size of the body portion to be formed such that two opposing sections of the one-piece element may be folded over to meet in the middle, where they are sewed onto the lower section of the one-piece element, which forms the body portion, such that the two guiding elements, each defining a separate channel, are created.
Preferably, the body portion may be three-dimensionally pre-shaped to conform to the limb, in particular by using darts, for example diamond darts. In concrete embodiments, the body portion may be laterally raised to provide a seating for the limb. In such an embodiment, the body portion does not fully wrap around the limb, but only partially, in particular around less than 50% of the limb. For example, the at least one lateral side edge from which the at least one band extends and its opposing lateral side edge may be raised. This indicates correct positioning for the limb and thus guides the person to correct donning of the compression garment. The limb may be inserted in its longitudinal direction between the raised lateral side edges into the opening for receiving the limb.
In a concrete, preferred embodiment, the body portion, two bands and two guiding elements can be formed from one basic element by sewing. The basic element may be one piece, i.e. have the bands integrally formed, or may have the bands sewed to it. The basic element comprises a central area designed to form the body portion, wherein the central area comprises two diamond darts adjacent to the lateral side edges, wherein the portions at the outer side of the diamond are not connected, such that two diamond wings are formed for each diamond dart. The bands are formed at or attached to diagonally opposite diamond wings, such that, when the diamond darts are sewed together, the bands extend from the so-formed lateral side edges of the so-formed body portion, in particular perpendicularly, wherein the lateral side edges are preferably slightly raised to conform to the shape of the limb The basic element further comprises two side flaps or side sections along the sides perpendicular to the lateral side edges, wherein the flaps can be folded to the second side of the so-formed body portion to create the channels for the bands and thus the guiding elements, which are preferably guiding sleeves. Preferably, both flaps may be attached in the middle of the central portion in one seam to provide both guiding elements.
In an especially preferred embodiment, the compression garment may comprise multiple bands extending laterally from the body portion to wrap around the limb, wherein a channel for each band is provided by the at least one guiding element, in particular and preferably a separate channel for each band. In this manner, bands can be provided across multiple sections of the body portion and/or the limb. For each of these bands, compression may be separately adjustable in a simple, guided and efficient manner. Providing separate channels for each band provides accurate guidance for each of these bands and thus for the whole donning process.
Preferably, for at least one pair of bands, the bands extend from opposing lateral sides, in particular lateral side edges, of the body portion to wrap around the limb side-by-side. In this manner, opposingly oriented bands may be used which, however, are parallel and adjacent in use. Such an opposing band design provides tensioning balance hand helps prevent the compression garment, in particular in case of a wrap, from migrating in one specific direction of applied tension.
In preferred embodiments, at least one of the at least one band and/or the body portion may comprise a measuring system, in particular for measuring elongation and/or tension, and/or for determining a compression level applied to the limb by the garment. Using such a measuring system further simplifies purposefully choosing a specific compression. For example, the measuring system may use indicia positioned on an elastic section of the body portion and/or at least one of the at least one band and an associated measurement device, such that the distance between the indicia can be measured. Hence, an elongation and/or tension is measured, which may then be correlated to a certain compression level. Such compression level measuring systems may, for example, be termed built-in pressure system (BPS). Of course, other types of measuring systems known from the art may also be employed, for example those using attachable indicia and/or magnetic interactions. In any case, preferably, a compression level applied to the limb is determined as a result of the measurement.
In especially preferred embodiments, the compression garment further comprises a pad, in particular an acupressure pad, to exert pressure to the limb under the first side of the body portion. Such a pad may have a characteristic shape to exert pressure on specific anatomical features, for example muscles. The pad is placed under the first side under the body portion in use, such that it is pressed against the limb by the first side of the body portion.
Preferably, the pad is a multi-dimensional topographical pad that provides areas of high and low pressure. In this manner, a certain, predefined pressure distribution can be achieved. In concrete, preferred embodiments, the pad may have at least one outward protrusion on its limbward surface, wherein the protrusion may have a T-shape and/or the protrusion may be dimensioned and/or positioned to contact predetermined regions of the limb in a given orientation of the pad. In other words, the topography may be chosen such that, due to the protrusions, higher pressure is exerted to certain anatomical features, while lower pressure is applied in other regions. A T-shape has been shown to be particularly advantageous for the foot, where, in different orientations, as further described below, different anatomical features may be pressurized, leading to an individually customizable acupressure effect.
Thus, it is generally preferred that the pad is an acupressure pad. Acupressure is a technique in which physical pressure is applied to acupuncture points, i.e., certain anatomical features, with the aim of providing comfort, in particular clearing blockages and the like.
In concrete embodiments, the pad may comprise a foam base layer and a topography layer having the protrusions. That is, the pad may comprise multiple layers, wherein the topography or, more concretely, the protrusions, are defined by at least one topography layer.
In especially preferred embodiments, the pad may be positionable under the body portion in multiple orientations. In this context, the pad may be held in place by the compressions garment in use, while it is also possible to use means for fastening the pad to or in the body portion.
Preferably, the pad may be removably attachable to the first side of the body portion by a fastening means and/or the body portion may comprise a pocket on its first side for receiving the pad. Preferably, the fastening means may comprise a hook-and-loop fastener for easy attaching and removing, in particular in different orientations.
To facilitate positionability in multiple different orientations, the pad, in particular the acupressure pad, may have the shape of a disk or square.
In such embodiments a topographical and/or geometric pad design, in particular an acupressure pad, is combined with an adjustable wrap such that sustained adjustable passive pressure is applied to acupressure and/or reflexology points on the body while at rest. This completely new approach allows acupressure and/or reflexology treatment, in particular for the foot and the hand, that no longer require the user to continually exert a force or bear weight to sustain the pressure effect. As explained, the pad, in particular the acupressure pad, may be designed to provide acupressure to multiple locations of the limb, while, in the preferred embodiment, the pad is designed to be releasably attached, for example via hook-and-loop fastening means, and be freely rotatable in the compression garment, in this case preferably a wrap. By using a pad geometry further comprising a base layer of foam, the conversion of pressure provided by the body portion into the topography layer of the pad is improved. In summary, a compression garment, in particular a wrap, may be provided which is intended to massage and stimulate acupressure point on a limb, for example the soles of a foot, during periods of rest and relaxation to help relieve tired, achy feet and legs. In particular, stress, pain and anxiety relief, calm feet and legs, improved circulation and improved sleep quality may be provided as benefits. Due to the preferably freely orientable pad, in particular acupressure pad, the person may choose which acupressure points are to be stimulated. If, for example, a T-shaped protrusion is used, four different orientations of the T may be proposed which can be chosen as suitable. Of course, other shapes departing from the T-shape are also envisioned, depending on the limb and the area where the pad shall be applied.
The guiding elements for the bands have proven to be very advantageous in combination with such a pressure pad, in particular acupressure pad, since adjustable, well-placed compression may be easily and intuitively be applied. When using a pair of juxtaposed bands extending from opposing lateral sides, even the risk of unintentional movement of the already positioned pad is minimized. However, it has been shown that a freely orientable acupressure pad itself, even without guiding elements for bands, is already advantageous.
Thus, in a second aspect, the invention also concerns a compression garment for providing acupressure to a limb of a person, comprising
Thus, an adjustable compression garment, in particular wrap, is provided to deliver passive treatment pressure to relieve stress and pain at the limb. The compression garment, in particular the wrap, having the pad can be configured to target different areas of the limb and/or use different pressure profiles, such that the person may choose orientation of the acupressure pad and compression to feel most comfortable and obtain the best therapeutic treatment effect and/or general improvement of well-being. The compression garment requires only the initial application energy to don the compression garment to provide sustained treatment pressure. It does not require an electrical energy source, gravity, or further energy from the person wearing the compression garment to provide the treatment effect. This allows the person to be at complete rest and, in particular, non-ambulatory while using the compression garment.
As already explained above regarding the first aspect of the invention, it is preferred that the compression garment comprises at least two bands extending from opposing lateral sides of the body portion for wrapping side-by-side around the limb. Tension balance and displacement protection are provided in this manner, as well as, as generally the case when using more than one band, the option of applying locally varied compression, that is, compression profiles.
While it is in principle possible to hold the acupressure pad under the body portion by the compression exerted by the body portion, in preferred embodiments, the acupressure pad may be removably attachable to the first side of the body portion by a fastening means, for example, as already discussed, a hook-and-loop fastening means.
Of course, as laid out above, it is also preferable to provide the guiding elements for the bands to gain the respective advantages. Thus, also for the compression garment of the second aspect, the body portion may further comprise at least one guiding element providing a channel for receiving the band and guiding the band back over the garment, in particular over itself, when the band spans over the first side to provide an opening for receiving the limb. All remarks regarding the guiding element and the compression garment of the first aspect of the invention also apply here, such that the same advantages can be achieved.
In a third aspect, the invention also concerns a method for donning a compression garment of the second aspect of the invention, wherein the acupressure pad is attached to the first side or placed into the pocket in a chosen orientation, and, after or while donning the compression garment, compression is adjusted using the bands. These steps can also characterize a method for providing acupressure to a limb, in particular a foot, of a person using a compression garment according to the second aspect of the invention.
In this manner, general acupressure relief can be provided on the limb in an adjustable manner, since the compression and the choice of acupressure or reflexology points on the limb are both adjustable. Sustained adjustable passive pressure can be applied to acupressure or reflexology points on the body while addressed.
Further details and advantages become apparent from the following description of concrete embodiments taken in conjunction with the drawings, in which:
In this case, the loop material 12 is a velour material, and, at least in the section of the band 6 covered by the loop material 12, the band 6 thus comprises a structural layer 15, namely the loop material 12, and a cushioning layer 16 for comfortable contact with the skin of the person wearing the compression garment 1. The body portion 2 may also have the cushioning layer 16 on its first side 3.
In the embodiment shown in
It is noted that in the embodiment of
In use, the limb extends through the opening 8, such that, by pulling the band end 11, a desired tension level for the band 6 can be chosen. As the band 6 also acts onto the second side of the body portion 2, the body portion 2 is also pressurized against the limb. Multiple bands 6 also allow choosing certain compression profiles along the length of the limb covered by the compression garment 1.
However, it is also possible to apply other types of measurement systems 20 in compression garments 1 according to the invention.
It is noted at this point that the band 6 and the body portion 2 may also be trimmable to customize the compression garment 1. For example, further indicia may be provided associated with certain limb circumferences.
The central area 27 comprises two diamond darts 29 al lateral sides 30 of the central area 27. The portions at the outer side of the diamond darts 29 are not connected and form diamond wings 31, wherein the bands 6 extend from diagonally opposing diamond wings 31.
As shown in
In the next step, two side flaps 33 are folded inwards back onto the second side 4 of the body portion 2 to meet in the middle at a central seam line 34 already indicated in
As shown in
To place the so-formed compression garment 1, still with loose bands 6, into a state ready-to-use, as illustrated in
Using two opposing bands 6 not only allows to adjust to different tension levels for each of the bands 6, but also provides tensioning balance and helps prevent the compression garment 1 from migrating in one specific direction of applied tension.
As can be seen, the bands 6 completely circumnavigate the compression garment 1 to improve tension distribution throughout the compression garment 1.
In preferred embodiments, the compression garment 1 additionally comprises an acupressure pad 37 as exemplarily shown in
In this embodiment, the pad 37, see
