DETAILED DESCRIPTION OF THE INVENTION

[0014] A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. The present disclosure should in no way be limited to the exemplary implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of a, an, and the includes plural reference, the meaning of in includes in and on.

[0015] As shown in FIGS. 1A and 1B, one embodiment of a truncal compression garment 100 is adapted for use by a user having a torso. A body portion 110 has dimensions so as to be able to be wrapped at least partially around a length of the user's torso. A supporting band 130 is made of an elastic material and can be located under the channeling and around the torso so as to hold the garment in place. A front closure 132 secures the body portion to the user. An integrated structured portion 120 is disposed on an inside part of the body portion 110 and encourages direct flow of lymphatic fluid within the user's torso. The integrated structured portion 120 includes a plurality of protrusions 124 that define a corresponding plurality of channels 122. The protrusions 124 massage areas on the user where normal flow of lymphatic fluid is restricted and the channels 122 allow for flow of the lymphatic fluid that has been re-routed by the massaging action.

[0016] In certain embodiments, the integrated structure 120 includes structures such as: channeling, protrusions, chip bags, ridges, or ribbing specifically designed patterns known to benefit lymphedema. The integrated structure 120 can include materials such as: foam, quilted fabric, silicone, gel, air, gel-infused foam, polymer beads, foam rubber, fiberfill or combinations thereof. The front closure can include a mechanical connection such as: a hook and loop fastener, a zipper, a plurality of snap buttons, a plurality of hook-sand-eyes, a plurality of magnetic closures, a drawstring, a buckle, or a strap, and combinations thereof. The integrated structure 120 can include an adjustable strap made of a material such as: slide adjusters, hook and eye adjusters, hook and loop (such as Velcro) adjusters, tie adjusters, clastic stretch adjusters, or ladder adjusters.

[0017] As shown in FIG. 2, one embodiment of a compression garment 200 can include sloped straight protrusions 124 and channels 122 that are used to direct lymphatic fluid to available and undamaged lymph vessels on the user's sides. Also, protrusions 124 and channels 122 can be included on a back portion 210 of the garment 200.

[0018] The integrated structure portion 120 can cover both a left side of the user's torso and right side of the user's torso or, as shown in FIG. 3, only one side of the body portion of the garment 300. When the integrated structure portion 120 covers only one side the body portion the front closure can be reversible in one embodiment. An clastic bottom portion 130 for holding the garment in place can also be affixed to the bottom of the integrated structure portion 120.

[0019] In one embodiment, a truncal garment encircles the body and combines the benefits of the secure fit of a bra (at least one strap and supportive band) with the distinct structures for lymph drainage recommended for certain lymphedema drainage pathways in the truncal region for improved convenience and comfort while wearing. Applicant has discovered that combining the two above-described truncal garment technologies results in a truncal garment made with structures for durable and effective wearing.

[0020] In one representative embodiment, the garment has a shoulder strap adjustment to allow for a more appropriate fit to each wearer's torso. The front of the garment has a closure so the wearer can more easily wrap and secure the torso with the compression garment. In a typical embodiment, the garment does not provide levels of compression higher than 20 mmHg according to a garment compression test done in accordance to RAL-GZ 387/1:2008-01, so it has relatively mild compression compatible with lounging or nighttime use. This garment can eliminate the need to have both a truncal compression garment and a channeled pad.

[0021] In another representative embodiment, the garment has a shoulder strap adjustment to allow for a more appropriate fit to each wearer's torso. Additionally, it can have channeled padding on only one side of the garment. The front of the garment has a reversible closure so the garment can be flipped depending on which side of the body requires the channeled attention. In a unilateral partial mastectomy for example, this configuration would allow less padding on the side of the body that was not affected, thereby minimizing discomfort that can accompany layers of foam or fabric. This reversible closure ensures minimal inventory for retailers stocking and fitting these devices for various wearers. The reversible front closure allows the wearer to wrap and secure the torso with the compression garment more easily.

[0022] The garment can employ structures that are designed to encourage lymph drainage from the breast, axilla, and back, which can include the following: [0023] Foam: Foam padding, often made from materials like polyurethane foam, memory foam, or latex foam, is widely used in medically padded devices due to its ability to provide cushioning and support while conforming to the body's contours. [0024] Gel: Gel padding is another common option, particularly in devices intended to reduce pressure and prevent pressure sores. Gel padding distributes pressure evenly and can help dissipate heat. [0025] Air: Air-filled cushions or padding are used to provide adjustable support and pressure relief. These can be adjusted to accommodate individual comfort and pressure distribution needs. [0026] Silicone: Silicone padding is often used in medical braces and orthopedic devices due to its flexibility, durability, and hypoallergenic properties. Silicone padding can provide cushioning while allowing for a certain degree of compression and movement. [0027] Gel-infused foam: Combining the benefits of foam and gel, gel-infused foam padding offers both support and pressure relief. This type of padding is often used in mattresses, wheelchair cushions, and orthopedic braces. [0028] Fiberfill: Fiberfill padding, typically made from polyester fibers, is soft and lightweight, making it suitable for padding in medical braces, splints, and garments. It provides cushioning while allowing for breathability. [0029] Polymer beads: These small beads, often made from polystyrene or similar materials, can be used as fillings in cushions or pads to provide adjustable support and comfort. [0030] Foam rubber: Foam rubber, also known as latex foam or sponge rubber, is another option for padding in medically padded devices. It offers cushioning and support and is resistant to mildew and bacteria.

[0031] Front closures for the garment can include the following: [0032] Hook-and-Loop (e.g., Velcro: This closure system uses hook-and-loop fasteners, to secure the garment. It allows for adjustable fit and easy adjustment, making it suitable for individuals with varying body shapes and sizes. Hook-and-loop closures are often found on compression wraps, braces, and post-surgical garments. [0033] Zipper: Zippers provide a secure closure and are relatively easy to operate. They are commonly used on compression garments, post-surgical bras, and orthopedic braces. Some medical garments feature zipper closures with protective fabric flaps or backing to prevent skin irritation or chafing. [0034] Snap Buttons: Snap buttons offer a secure closure and can be easier to manipulate than zippers for some individuals. They are commonly used on compression vests, abdominal binders, and post-surgical garments. Snap buttons provide adjustable fit options and can withstand repeated use. [0035] Hook-and-Eye: Similar to the closures found on bras, hook-and-eye closures feature hooks on one side of the garment and fabric loops (eyes) on the other side. They provide a secure closure and are often used on compression bras, abdominal binders, and post-surgical garments. [0036] Magnetic Closures: Magnetic closures use magnets embedded in the fabric to fasten the garment together. They offer a convenient and easy-to-use closure option, particularly for individuals with limited dexterity or strength. Magnetic closures are commonly found on compression wraps, post-surgical garments, and adaptive clothing. [0037] Drawstrings: Drawstrings are used to tighten or loosen the garment around the body. They provide customizable fit options and are often found on compression garments, post-surgical vests, and orthopedic braces. Drawstrings may feature cord locks or toggles to secure the closure in place. [0038] Buckles: Buckles provide a secure closure and are commonly used on orthopedic braces, splints, and support belts. They offer adjustable fit options and are designed to withstand movement and tension without coming undone. [0039] Compression Straps: Some medical garments feature compression straps with hook-and-loop closures or buckle fasteners. These straps allow for adjustable compression and secure fit, making them suitable for compression wraps, braces, and support garments.

[0040] Shoulder adjustments for the garment can include the following: [0041] Slide Adjusters: Slide adjusters, also known as slide buckles or sliders, consist of two small pieces of metal or plastic that slide along the length of the bra strap. By moving the adjusters up or down, the wearer can increase or decrease the length of the straps to achieve the desired fit. Slide adjusters are widely used in compression bras and offer precise adjustment options. [0042] Hook-and-Eye Adjusters: Similar to the closures found on bras, hook-and-eye adjusters feature hooks on one end of the strap and fabric loops (eyes) on the other end. The wearer can adjust the length of the strap by attaching the hook to different eyelets, providing multiple fit options. Hook-and-eye adjusters offer versatility and are commonly found on compression bras. [0043] Hook-and-Loop Adjusters: Some compression bras feature hook-and-loop adjusters on the straps, allowing for easy and quick adjustment. The hook-and-loop strips adhere to each other to secure the strap at the desired length. Hook-and-loop adjusters are convenient for individuals with limited mobility or dexterity. [0044] Ribbon or Tie Adjusters: Some compression bras feature straps made of soft fabric ribbons or ties that can be tied or untied to adjust the length. This allows for customizable fit options and may be suitable for individuals who prefer a more adjustable and flexible design. [0045] Elastic Stretch Adjusters: Elastic stretch adjusters are built into the bra straps, allowing them to stretch and conform to the wearer's body while providing support. These adjusters offer flexibility and comfort, making them suitable for compression bras intended for active wear or everyday use. [0046] Ladder Strap: The shoulder strap of the bra is typically constructed with a strip of fabric that contains a series of evenly spaced slots or openings running vertically along its length. These slots resemble the rungs of a ladder, hence the name ladder adjustment. Attached to the end of the shoulder strap is a small plastic or metal device called a slider or adjuster. The slider has a protruding tab or bar that can be inserted into one of the slots on the ladder strap.

[0047] Fabrics used to make the torso encircling garment can include a stretchable material to provide compressive force against the torso. Other examples of such fabrics include flat knit fabrics, circular knit fabrics, antimicrobial fabrics, and moisture wicking fabrics.

[0048] Having the structures directly against the body without any barrier can allow the padding to be in full contact against the skin. Also, having only one unit to don and doff provides simplicity in many ways and convenience for the user.
