Description

IMPROVED COMPRESSION GARMENTS FOR EASE OF USETechnical Field

[0001] The embodiments disclosed herein relate to compression garments, and, in particular, to pants which provide compression.Background

[0002] Medical compression garments are commonly used to offer compression therapy for improved venous return. By providing a gradually decreasing compressive force starting from the lower end of an extremity, often a leg, they assist the wearer’s venous return system by promoting the blood flow back to the heart. Such garments are often made from elastic knitted fabric, and are conventionally designed as hosiery stockings, socks, sleeves, bandages, etc.

[0003] However, traditional medical compression garments are generally not well tolerated by wearers nor are they used as frequently as needed to benefit from their therapeutic advantage. Wearers find them extremely difficult to put on, uncomfortable with a slippery and unstable waist band, hot and impractical due to the need to layer up the see-through hosiery, and limited in fashionable style. Although below-the-knee compression socks and sleeves are generally well tolerated by wearers, patients with conditions that require full-leg compression therapy are currently limited to hosiery stockings as their main therapeutic compression solution. There is a strong need for compression garments at the therapeutic level with a design that encourages sufficient use and user compliance.

[0004] While therapeutic compression garments are often developed for patients with a range of diagnoses, compression garments at an appropriate compression grade are also beneficial for athletes and for those with a lifestyle having long hours of sitting or standing who, as a result, frequently experience tired and aching legs. However, the aforementioned limiting factors of current medical compression garments discourage these populations from the use and benefits of therapeutic compression garments.

[0005] Accordingly, there is a need for compression garments which are easy to use, comfortable, and fashionable while still providing the benefits of compression.Summary

[0006] Provided herein are systems and methods for a compression garment comprising of 4-200 denier knit or woven fabric configured to cover a mid-torso to lower limb area of a wearer when the garment is worn, wherein the fabric has a compression grade of 10-50 mmHg, and wherein the fabric supports garment donning and / or functional features comprising at least one of: at least one zipper, at least one button, at least one pocket, belt loops, reinforced stitching, a fly, magnetic closure, hook and loop fasteners, hooks, and strings.

[0007] The threads of the knit or woven fabric may be interlaced with variable tension to provide variable levels of elasticity in a single piece of fabric.

[0008] The compression of the garment may have greater mmHg at a distal end of the lower limb than at a proximal end of the lower limb.

[0009] The mmHg of the garment may gradually decrease from the distal end to the proximal end and wherein a single piece of fabric provides the compression for the length of the lower limb,

[0010] The compression garment may comprise at least two different pieces of fabric along the length of the lower limb providing variable compression to the lower limb.

[0011] The compression may be suitable for medical compression, sport or fitness applications, bodyshaping applications, and / or wellness and comfort applications and casual daily use.

[0012] The compression garment may comprise one of: compression leggings, pants, shorts, tights, trousers, denims, scrubs, socks, underwear, a compression sleeve for just one leg, and undergarment base-layers.

[0013] The compression garment may be comprised of at least an elastic yarn.

[0014] The elastic yarn may be selected from the group comprising of a synthetic or natural elastane and elastodiene yarn.

[0015] The elastic yarn may be present with a filament yarn selected from a group comprising of polyester, polyamide, polypropylene, polyacrylonitrile, polyisoprene, nylon, cotton, hemp, wool, linen, silk, viscose, Tencel, lyocell, bamboo, modal, and micro modal.

[0016] At least one compression portion of the garment may be removable from the rest of the garment.

[0017] At least one sleeve of non-compression fabric may be removably attachable to the garment.

[0018] At least one electronic monitoring device may be embedded in the fabric to monitor at least one health metric. The at least one electronic monitoring device may be sewn into the garment to monitor at least one health metric. At least one electronic monitoring device may be attached or otherwise communicatively coupled to the fabric.

[0019] The compression garment may be treated with at least one of an antimicrobial agent, an anti-pilling agent, and anti-snagging agent, a UV protection agent, a moisture wicking agent, a cooling agent, a thermoregulating agent, and a color fastness agent.

[0020] The compression garment may be custom-fitted for the wearer.

[0021] Other aspects and features will become apparent to those ordinarily skilled in the art, upon review of the following description of some exemplary embodiments.Brief Description of the Drawings

[0030] Various apparatuses or processes will be described below to provide an example of each claimed embodiment. No embodiment described below limits any claimed embodiment and any claimed embodiment may cover processes or apparatuses that differ from those described below. The claimed embodiments are not limited to apparatuses or processes having all of the features of any one apparatus or process described below or to features common to multiple or all of the apparatuses described below.

[0031] The present invention provides systems and methods for medical, athletic, or lifestyle compression garments, with improved features. Herein, the compression garments are pants, to be worn on the legs, but the features described may be applied to tops as well. The compression pants combine therapeutic advantages of existing medical compression stockings with the design and functionality of a pair of slim fitting pants (i.e., with some of the features ofconventional non-compression pants). A garment designed for partial or complete coverage of the legs, such as trousers, shorts, leggings, tights, denim, etc., the compression pants can sit above the ankles and terminate at the waist region. Compression pants are developed with opaque knitted or woven fabric that is not hosiery or see-through, and comprise of an elastic material composition that can provide variable ranges of compression, preferably between 10 to 50 mmHg.

[0032] Compression garments may be prescribed or recommended as a venous health management treatment for any number of conditions, such as diabetes, lymphedema, lipedema, postural tachycardia syndrome (POTS), deep vein thrombosis (DVT), and varicose veins, as well as for people who are pregnant or post-partum, have a sedentary lifestyle, are engaging in fitness activities or recovery, or are taking a flight.

[0033] The above groups cover a large percentage of the population, as many as one third of the population, however, most of these people (up to 90%) do not wear compression garments as they are impractical for daily wear. As described above, traditional medical compression garments are generally not well tolerated by wearers and poor compliance results in a loss of effective therapeutic advantage. Current compression garments most often comprise thin and sheer material which cannot support features of conventional garments (e.g. pockets, zippers, loops, other donning features, etc.) and require other layers of garments to be worn. Wearers find compression garments difficult to put on, uncomfortable, inconvenient to layer, impractical due to the see-through nature of the hosiery, and limited in fashionable style.

[0034] Improved compression garments which address the gaps and pain points of current compression garments will encourage compression garment use and enhance the experience of users. The addition of features of conventional garments, such as buttons, zippers, belt loops, and pockets, to compression garments, as described herein, provides a more functional, comfortable, and aesthetically pleasing garment for daily wear, to improve the compliance rate for compression therapy.

[0035] The design of the compression pants described herein addresses the limitations of existing compression garments to encourage adequate use. For example, the pants may comprise an opaque fabric of an appropriate thickness to provide a sturdy surface area for the wearer to grab on to when pulling up the tight compression garment, and therefore offer greater safety and ease for putting on the garment without ripping. As another example, a defined waistband to which belt loops and / or zippers could be added would alleviate any challenges with donning and a slippery waist portion of the garment.

[0036] The compression pants discussed herein offer the opportunity for introducing variable design features such as zippers, buttons, pockets, stitches, etc., that would not only bringversatility, but contribute to the comfort and ease of putting on the garment. A further advantage of the compression pants is fashionable appeal so they can be worn alone, or layered if desired.

[0037] The compression pants may comprise any combination of the following features: 1) graduated compression with the highest level of compression at the distal end, and lowest level at the proximal end, with a compression range anywhere between 10-50 mmHg 2) opaque fabric throughout the garment that is not see-through so that it does not need to be layered, 3) seamless construction and / or use of flat stitches and adhesives to minimize skin irritation, 4) garment construction that allows for the use of features that alleviate the difficulty of donning or inserting a limb into the tight fitting compression garment such as zippers, belt loops, etc., 5) the garment may be of any length where the proximal end terminates at the waist, and the distal end may terminate anywhere on the lower limb, 6) the garment may be constructed with multiple panels of fabric joined together or constructed as a single tubular garment, 7) may be referred to as pants, trousers, shorts, leggings, tights, scrubs, stockings, jeans, denim, sleeve, etc. 8) Can be constructed as a knit or woven fabric.

[0038] As described above, provided is a compression garment of a knitted or woven fabric of appropriate thickness that can be worn as a fashionable everyday garment, which has the appearance of a normal garment and allows for integration of fashion design and functional features such as pockets, zippers, patterns, etc. An example of such a compression garment is shown in Figure 1.

[0039] Figure 1 is a schematic diagram of a front view of an example pair of compression pants 100 having features which provide ease of use as well as visual appeal to the compression garment to enable greater uptake and use of the garment.

[0040] Compression pants 100 have legs 110 which provide compression due to the tightness of the leg and the material used to create the pants. The legs have a seam 115 along the front to add visual appeal.

[0041] Compression pants 100 have a defined waistband 120 which is separate from the rest of the garment wherein the waist is closable by a zipper 130 with a button closure 135. The defined waistband 120 adds visual appeal as well as enabling the addition of the zipper 130. The zipper 130 allows for ease in putting on and removing the compression pant 100.

[0042] The defined waistband 120 sits in the waist region, is connected with a hip portion of the garment, and offers shaping or control characteristics.

[0043] Figure 1 shows a pair of compression pants, however, in other embodiments of the compression garment may advantageously be any of a pair of trousers, leggings, tights, or shorts, which lay directly on the skin of the wearer as a slim-fitting compression garment.

[0044] The material or materials used for the compression garment may be any appropriate material and thickness that allows for addition of functional features such as zippers, buttons, belt loops, etc. to prevent undue difficulty of donning or inserting a limb into the tight fitting compression garment, and introduce stylish designs to encourage more frequent use by the wearer.

[0045] The compression garment is formed of a stretchable fabric. The stretchable fabric may be made of any variety and combination of natural or synthetic elastic fibers, including but not limited to polyester, polyamide, polypropylene, polyacrylonitrile, polyisoprene, nylon, cotton, hemp, wool, linen, silk, viscose, Tencel, lyocell, bamboo, modal, and micro modal.

[0046] The compression pants comprise a fabric and material that offers sufficient opacity and thickness for the garment to be worn alone, without any sheer effects and without the need for additional covering layers. As such, the weight of the fabric may vary from 4 to 200 denier.

[0047] The compression garment may be made with variable amounts and combinations of elastic and strength fibers to achieve the desired compression.

[0048] Compression is exerted upon the leg when the garment is worn by the wearer, which results in circumferential portions of the compression garment being stretched. The degree of elasticity of the fabric as a given location as well as the circumference of the leg at the same location determines the amount of compression force which is applied to at a given location on the leg.

[0049] In some embodiments, the compressive force exerted by regions of the compression pants may vary quite gradually along the garment, without sudden and significant changes from one region to the next. In some embodiments, the level of compression may vary uniformly along the axial direction, while in other embodiments, the circumferential compression may increase and / or decrease as desired along the axial direction, offering a variable compressive force along the garment.

[0050] In a preferred embodiment, the circumferential compressive force decreases gradually along the axial direction, with the highest compressive force applied at the distal end. In some embodiments, the proximal end including the hip and waist region may comprise zero or considerably low compressive force to offer maximal comfort to the wearer.

[0051] In one embodiment, as shown in Figure 2, the elasticity of the garment changes throughout the length of the fabric to accommodate different compression zones due to the need for different levels of compression at different locations on the leg, and to minimize excessive restriction on the wearer’s skin. That is, the compression garment has different degrees of circumferential compression at a plurality of different axial locations of the circumferential portioncontinuously and without using different and separate sections of fabric in order to provide different compression forces.

[0052] Figure 2 shows a schematic diagram of pair of compression pants 200 with graduated compression. The schematic diagram of Figure 2 is simplified compared to the compression pants of Figure 1 , however, the compression pants 200 of Figure 2 may include any of the features of compression pants 100 (e.g., defined waist, zipper, etc.).

[0053] The compression pants 200 may be any length which covers a portion of the legs of the wearer.

[0054] The compression pants 200 has a graduated compression along the length of the leg. The arrow shows the direction in which compression is increasing, with compression being less at a first end 211 which is closer to the waist of the compression pants 200 and gradually increasing to have the most compression at the second end 212 which is closer to the ankle of the compression pants 200.

[0055] In an embodiment, the compression pants may comprise a single piece of seamless fabric (herein “seamless compression pants”) or a single piece of seamless compression fabric joined to a waistband.

[0056] In other embodiments two or more pieces of fabric may be joined to form a seam (i.e., a line where two or more pieces of fabric are joined together by stitches or other means) and attached to a waistband to form the compression pants.

[0057] In one embodiment with multiple pieces, a leg section may comprise a single piece of fabric and two leg sections may be sewn together to create the compression pants 200.

[0058] In another embodiment with multiple pieces, the compression pants 200 may comprise a single front piece which is the front of both legs and a single back piece which is the back of both legs, and the front piece and back piece may be sewn together to create the compression pants 200.

[0059] In an embodiment with two single leg pieces sewn (or otherwise joined) together, one of the legs may have different compression compared to the other leg.

[0060] In an embodiment with a back panel and front panel sewn (or otherwise joined) together, the fabric on the back of the compression pants may have a different elasticity than the fabric on the front.

[0061] In some embodiments, the compression pants 200 may be seamless. In other embodiments, the compression pants 200 may include fabric panels (as described above) connected by connection means such as glue or a flat stitch in order to reduce irritation or discomfort for the wearer.

[0062] Regardless of the construction of the compression pants 200 the fabric has a gradual decrease in elasticity from the first end 211 to the second end 212 to enable greater compression at the ankle than at the thigh.

[0063] In other embodiments, uniform compression along the length of the leg may be desired and the change in elasticity of the fabric from the ankle to the waist may be designed to maintain the uniform level of compression.

[0064] In other embodiments, the change in elasticity of the fabric may not be gradual along a length of the compression pants but instead there may be sections of the compression pants with provide no compression. For example, the fabric may have an elasticity at the calf and the thigh that enables compression but may not have any compression around the knee.

[0065] For the various embodiments of compression along the length of the leg, the fabric is manufactured to have the desired variable elasticity along an axis that will be along the length of the leg. Any desired order of elasticity, whether gradual changes or abrupt changes, may be manufactured.

[0066] In a preferred embodiment, the compression garment exhibits sufficient stretch recovery to maintain its intended compression grade for prolonged periods of wear.

[0067] The compression pants described above may be used for the management and prevention of venous insufficiency commonly known as poor blood circulation, lymphedema, thrombosis, diabetes, or other venous and lymphatic system dysfunctions. The compression pants may also be used as a compression garment for fitness and bodyshaping purposes, as well as use for an enhanced blood circulation or casual wear without necessarily a diagnosis or health dysfunction.

[0068] The proximal end of the compression pants can be adapted to terminate in the hip or waist region of the wearer, and as high as the rib region. At the distal end, the compression pants can be adapted to end around the ankles or cover the feet and toes for full leg coverage, or terminate anywhere on the thighs or below the knees for a partial coverage, referred to as “shorts”. Some patients require full-leg compression therapy that covers the legs distally at least as far as the ankles, and may therefore require full coverage compression pants. Higher compression levels are often most applicable for full-leg coverage compression pants, as opposed to partial coverage, to minimize any restrictions imposed on the wearer’s blood flow. Any length between the aforementioned “full coverage” and “shorts” may also be contemplated.

[0069] Figure 3 is a schematic diagram of a pair of compression pants 300 with removable compression portions 310 and 320.

[0070] The compression pants 300 provide compression along a length of the leg of a wearer but also comprise removable portions 310 and 320 which are connected to a top portion 330 by connections 311 and 321 , respectively. The connections may be provided by zippers, hook and loop fasteners (e.g., Velcro™), buttons, etc. Removing the removable portions 310 and 320 changes the compression pants 300 from full coverage compression pants to compression shorts.

[0071] Figure 4 is a schematic diagram of a pair of compression pants 400 with removable non-compression portions 410 and 420.

[0072] The compression pants 400 include full coverage compression pants 405 and removable non-compression portions 410 and 420 which are attached to full coverage compression pants 405 at connections 411 and 421 .

[0073] The removable non-compression portions 410 and 420 comprise fabric which does not fully contact the skin and which does not provide any compression for the wearer. Attachment of the non-compression portions 410 and 420 to the full coverage compression pants 405 provides a visual that the pants are not compression pants by hiding the lower part of the full coverage compression pants 405 under looser fabric.

[0074] In other embodiments, the removable non-compression portions may be attachable to short compression pants, for example top portion 330 of Figure 3, to convert short compression pants into full length pants which do not look like conventional compression pants.

[0075] In further embodiments a compression garment may be modular and may comprise a top portion, for example top portion 330 of Figure 3, and both compression and noncompression portions that can be attached to the top portion as desired.

[0076] Further characteristics which are either desired or possible for compression garments (particularly pants), as well as various methods of manufacture, are discussed below.

[0077] Woven and Knit Fabric

[0078] Conventional woven garments typically offer no or little stretch, however, stretch woven fabric can be used for compression garments. Manufacturing stretch woven fabric involves the use of a substantial amount of elastic yarn to provide elasticity. As described above the amount of elastic yarn at a specific location within stretch woven fabric and subsequently at a specific location within a compression garment can provide areas of high compression where desired. An advantage of a woven stretch construction is that woven fabrics are more enduring and resistant to tearing. In woven textiles, the strands are intertwined to form a sturdy structure that can endure frequent usage and washing. A challenge for wearers of conventional knit compression garments is that said garments may have the user replace the product every 3-6months depending on frequency of use, due to the interlocking loops stretching out. Compression garments can only offer the intended health benefits if the fabric effectively maintains tension throughout the garment. Frequent replacements result in higher amounts of textile waste in the environment, as well as frequent purchases and spending for the user.

[0079] Knit compression garments are the conventional type of compression, and have been shown to be an effective and harmless compression for the wearer. Knit fabric is also typically softer and offers a greater amount of stretch.

[0080] The compression garments (e.g., pants) described herein may use woven or knit fabrics to achieve compression. When the garment includes multiple panels woven and knit fabrics may be used in the same garment.

[0081] Graduated Compression and Targeted Compression

[0082] For the compression garment / pants described herein, there are a few different methods of construction that can be used alone or in combination for developing this garment. Some possible patterns of compression were described above. Methods of achieving the various patterns of compression are described below.

[0083] 1) Cut & Sew: using one or multiple panels of fabric, with each panel woven or knit with a consistent level of tension. To create a graduated compression effect with a cut and sew method, several factors are considered including the sizing of different parts of the garment and the design and shape of each fabric panel. For example, a garment with graduated compression may use different panels of fabric each with a different elasticity level for an overall graduated compression effect. Printed fabric or adding print onto fabric may serve to reinforce areas of compression.

[0084] Generally, graduated compression refers to 100% compression at the ankles or the lowest point of the garment, with a gradual decrease in the level of compression towards the upper point of the garment, such as the hips and waist in full-length pants. However, any amount of compression may be present at the ankle and decrease upwards.

[0085] 2) Variable tension: constructing fabric with varying levels of compression within a single or multiple pieces of fabric. To create a piece of fabric with variable compression the yarn tension and / or elastic composition is manipulated as the fabric is being woven or knit. This can result in a large dimension of fabric to be used for bulk manufacturing or a small area of fabric to be used for made-to-order garments.

[0086] Generally, targeted compression involves variable levels of compression that accommodate for areas of muscle groups in the body. For example, the garment may use the variable tension constructions methods to create a 100% compression around the calves, andvariable compression gradients in other parts of the garment depending on the use-case of the garment.

[0087] 3) Circular / seamless weaving or knitting: constructing garments with no or few seams. Seamless garments may combine the cut and sew and variable tension methods as described above to create a garment which has either no seams or very few seams which use connection means and / or are positioned to minimize irritation to the wearer.

[0088] Opacity

[0089] Fully opaque: the garment / pants may be constructed using a sufficiently dense and thick-diameter fabric, or construction techniques such as tightly knit / woven fabric for a fully- opaque and non-see-through appearance. This provides a more versatile and user-friendly garment since the user does not need to layer up the garment for modesty or warmth.

[0090] A challenge for wearers of conventional hosiery compression stockings experience is the thin and weak structure of the hosiery fabric. Donning compression apparel takes considerable effort and continuous pulling of the garment to pass the tight fitting fabric against the skin. This may result in the hosiery fabric being ripped, or the wearer facing difficulties putting on the garment while trying to avoid rips. Therefore, the compression pants as described herein comprise a sturdy fabric of considerable thickness, strong tension, and weaving or knitting structure to offer sufficient strength that allows the wearer to grab and pull on the fabric when donning.

[0091] Sheer: the garment / pants may be constructed of a light and thin layer fabric, using delicate micro-yarns. The garment can have variable amounts of sheer and see-through appearance, with a weight 4-200 denier. This provides individuals living in warm climates, or wearers such as physicians that desire compression therapy during work hours due to prolonged standing, with light and thin garments that offer compression benefits that can be worn in warm weather and / or under uniforms, dresses, etc. However, the sheer material stills needs to be sturdy for the wearer to grip and pull on the fabric when donning and therefore have a strong tension and woven or knit structure which offers sufficient strength.

[0092] Elastic And Filament Yams

[0093] The compression garment described herein may be made with variable amounts and combinations of elastic and strength fibers, made of a variety of natural or synthetic elastic fibers, including but not limited to polyester, polyamide, polypropylene, polyacrylonitrile, polyisoprene, nylon, cotton, hemp, wool, linen, silk, viscose, Tencel, lyocell, bamboo, modal, and micro modal.

[0094] Flat Seams

[0095] Because compression garments are tight fitting garments, skin irritation can occur if the seams are not flat and minimal. However, not all stitching methods accommodate for any or sufficient stretch along with a stretch fabric. Methods which allow for stitching elastic material are discussed below.

[0096] Adhesive tape / bond: using thin adhesive or iron-on clothing tapes of appropriate stretch levels in place of seams for areas where the integrity of the seam can be maintained e.g. pockets, ankles, waist band.

[0097] Merrow stitching: a relatively flat stitching that does not result in a diameter of folded fabric on the skin. Merrow can involve a highly dense stitch, which allows for sufficient stretch.

[0098] Stitched on the outside: this can be an “inside-out-stitch”, or as an example, top stitching that maintains the aesthetics of the garment while posing minimal irritation to the skin. Stitching on the outside may be useful for outseam and inseam stitches. Fabric can be stretched while stitching to ensure that the stitch does not break on a stretchy fabric.

[0099] Serge / overlock stitching: this stitch allows for a great amount of stretch, and results in a relatively flat area of layers of fabric being joined together. However, serge / overlock stitching can result in a bulky seam if the fabric is relatively thick. Serge / overlock stitching is, therefore, best for pocket linings, gussets, and seams on a thin fabric.

[0100] Ultrasonic cuts instead of stitches: Ultrasonic cuts used instead of seams for the ends of a fabric provide an advantage because it can offer a clean look and not irritate the skin. Ultrasonic cuts are best used for hems, waist bands, and pockets.

[0101] Seamless: a seamless structure involves no or minimal seams throughout the garment. This can include knit or woven construction.

[0102] Fly At the Waist

[0103] Compression garments are tight fitting apparel to provide the intended benefits to the wearer. However, putting on a tight fitting garment can present a significant challenge for some users of conventional compression products. Whether it be due to limited mobility, pain and weakness in the limbs, or simply inconvenience, this challenge often deters people from wearing their compression garment and managing their health. Literature has shown about 80% treatment non-compliance with compression therapy due to factors including existing solutions being uncomfortable, impractical, and out of style.

[0104] As shown in Figure 1 , the compression pants described herein may include a fly at the waist of the garment. The fly may be in the form of a zipper opening, button(s), folded fabric, pin(s), hook and eye, hook and loop fasteners (e.g., Velcro™), etc. The fly at the waist creates alarger opening for the wearer to place their feet and subsequently their calves, knees, thighs, and hips through when donning the garment, hence reducing the restriction and effort for putting on the pants.

[0105] In some embodiments, in cases where a larger opening at the waist and hips would help wearers such as those with limited mobility and dexterity to put on the garment, various new designs of a fly may be used. For example, typical flies with zippers or buttons provide a circumferential area that is mostly limited to the circumferential width of the garment. A fly design to address this challenge may be made of a larger surface and circumferential area to begin with.

[0106] Figures 5A-5E are schematic diagrams illustrating an example of a fly design with a larger circumferential width than rest of the garment.

[0107] Figure 5A shows a front view of a pair of compression shorts 500 with a waistband520 above the lower portion 510 which provides compression. A circumference 521 at the top of the waistband 520 is greater than a circumference 522 at the bottom of the waistband 520.

[0108] Figure 5B shows a close-up front view of the waistband 520 with circumference521 at the top and circumference 522 at the bottom. The waistband 520 is in an open position.

[0109] Figure 5C shows a close-up front view of the waistband 520 with circumference 521 at the top and circumference 522 at the bottom. The waistband 520 is in a closed position. Dotted line 525 represents a folded over portion of waistband 520 wherein the waistband 520 has been folded over and a fly has been closed by a button, hook, or other closure means (not shown). The width, as seen in the front view, of circumference 521 in the close position is less than the width of circumference 521 in the open position.

[0110] Figure 5D shows a close-up top-down view of the waistband 520 showing only circumference 521. The waistband 520 is in an open position.

[0111] Figure 5E shows a close-up top-down view of the waistband 520 showing only circumference 521 . The waistband 520 is in a closed position. Area 525 represents a folded over portion of waistband 520 wherein the waistband 520 has been folded over and a fly has been closed by a button 530. The width, as seen in the front view, of circumference 521 in the close position is less than the width of circumference 521 in the open position.

[0112] Figure 6A and 6B shows a garment with an upper portion that tapers out towards the waist to increase ease in putting on the garment.

[0113] Figures 6A and 6B show a front view of a pair of compression shorts 600 which have a larger circumference at the top than is necessary for the size of the wearer, which enables the wearer to more easily pull on or take off the garment.

[0114] Compression shorts 600 have a waistband 620 above the lower portion 610. The waistband 620 has thereon a button 630 and a fastening panel 635 with a buttonhole.

[0115] In Figure 6A the compression shorts 600 are in a relaxed or open state wherein the button 630 is not held within the fastening panel 635.

[0116] In Figure 6B the compression shorts are in a closed state wherein the fabric of the compression sorts is folded over (represented by dotted line 625) and the button 630 is held within the fastening panel 635.

[0117] Aesthetic And Functional Features

[0118] Fasteners And Notions

[0119] The garment may include zippers, buttons, hooks, strings, magnetic and hook and loop fasteners (e.g., Velcro™ ) enclosures, fusing and interfacing, belt loops, pockets, etc., which may serve several different purposes, including adding to the garment’s style, structure, and functionality. All of the mentioned elements are tested and studied for their compatibility with stretchy fabric, since they should not restrict the compression level or overall strength of the garment.

[0120] These features may increase functionality. For example, magnetic closures, hook and loop fasteners (e.g., Velcro™), and zippers may be placed vertically near the ankles to help with easier donning and doffing, as long as it does not compromise the compression integrity of the garment or irritate the skin. Additionally, waist drawstrings, belt loops, and pockets may enhance the usability and functionality of the garment for the wearer.

[0121] These features may increase structural integrity. For example, buttons, hooks, and zipper may be used as reinforcement throughout the garment such as the fly and waistband, and proper selection of fusing and interfacing is critical. Working with stretchy fabric can be challenging as the fasteners and notions also tolerate and accommodate for when the fabric is stretched, and not rip or lose their structural integrity due to the stress of elongation. Therefore, heat-activated fusible tape / adhesive and tricot fusible interfacing which match the stretchability of compression fabric and maintain structure when the garment is stretched, may be used in the waistband. Single or double-sided adhesive tapes that can be stretched can also be used for various purposes, such as the hems, lining the pocket openings, or the waistband.

[0122] The features may provide visual appeal or style. Features used in the compression pants are incorporated with the style of the garment in mind, to ensure that the wearer is not discouraged from wearing the pants, to therefore enhance user compliance.

[0123] Gusset And Inner Thigh Lining

[0124] Regular tight fitting pants often result in rips and tears near the inner thighs and the crotch, due to the surface tension along the layers of fabric that rub against each other with use. Solutions to prevent this wear and tear may include: i) Lining the gusset with an extra layer of breathable fabric, or ii) Lining inseam sections or not having an inseam stitch, as most thigh rubbing occurs through the inseams.

[0125] Construction Features for Size Variations

[0126] For most garments, different sizes are made based on a semi-consistent degree of length increase / decrease for each size. However, accommodating different sizes is challenging when the fabric is a stretch fabric and the level of compression that the garment is to be consistent for every size.

[0127] A size chart tailored for compression garments is used as a basis for manufacturing. The size chart can be adapted from online databases such as the Alvanon, or could be customized. Customization can be done by making a sample garment for a model leg with known measurements, and measuring the compression grade at every circumferential point using any compression testing device. From there, the circumferential width and degrees of curvature of the garment is decreased or increased to achieve the intended compression grade. It is ideal to use either an adaptive leg model with varying measurements, or multiple leg models to perform this process for every size in which the garment is made.

[0128] While the measurements of most sections of the garment will be different for every size, some sections will have the same measurement. For example, the fly, pockets, belt loops, and the waistband’s axial length will not change across different sizes.

[0129] In some embodiments, garments may be custom fitted or custom manufactured. In one example, a compression garment of a high compression grade that is used for the treatment and management of a health condition such as lymphedema, may be developed to match the particular sizing of a user or a demographic.

[0130] Interchangeable design

[0131] The compression garments described herein focus on design and style of the garment, and how confident and comfortable the wearer feels in the garment. With this approach, and the introduction of functional features, fasteners, and accessories in the making of the garment, including but not limited to zippers, buttons, hooks, strings, magnetic and hook and loop fasteners (e.g., Velcro™) enclosures, the garment can be made of multiple panels and layers that serve an aesthetic and functional purpose. As Shown in Figures 3 and 4, these panels and layers can be detachable and add-ons. Fabric layers and panels may have different weights, thicknesses, materials, and compression grades. The attachment points may also allow different garments to be attached and worn together, instead of being limited to just one set.

[0132] In various embodiments, the garment may be made of multiple individual garments, including a pair of shorts that extend anywhere below the hips, and a pair of sleeves that can be attached to the shorts using any form of fasteners to be worn as a pair of pants. In another example of a garment being made of multiple individual garments or pieces, a pair of tight fitting compression pants may have an attachment point to fasten another layer of loose fitting garment along the waist, fly, or at any point along the leg. This would be particularly useful in cases where the user prefers the use of pants with a relaxed style, while having to wear compression garments for their health and functional benefits.

[0133] Use Of Sensory Technology in The Garment

[0134] The compression garment may be made with or without sensory and computational textiles. This can be in the form of microchips embedded in the fabric, or a small monitoring device placed systematically in the garment. Figure 7 shows a piece of a compression garment 700 with a microchip 710 sewn into the fabric by stitching 720.

[0135] The compression garment may incorporate “smart” compression design, and data may be collected from the wearer through sensory touch that can inform the wearer or a designated healthcare provider of various health metrics. Knits as well as stretch woven textiles allow for the use of this technology due to the small gaps that exist in the constructional pattern of the textile.

[0136] Finishing And Treatments

[0137] The yarn, fabric, and / or finished compression garment can be treated with chemical agents for various purposes. Dyes can be used to change the color of the garment, and chemical treatments and coating may be done at different stages of the production process to introduce antimicrobial (e.g. copper, silver chitosan), anti-pilling, anti-snagging, UV protection, moisture wicking, cooling, thermoregulating, and greater color fastness.

[0138] While the above description provides examples of one or more apparatus, methods, or systems, it will be appreciated that other apparatus, methods, or systems may be within the scope of the claims as interpreted by one of skill in the art.
