DETAILED DESCRIPTION OF THE INVENTION
(36) The present invention is directed to a device having a bridge portion adapted for releasable adherence to a patch of skin so as to lift the patch of skin above a sensitive underlying treatment site in reducing discomfort or pain associated with tissue compression at the treatment site. The device is positioned on the patient such that the bridge portion is elevated above the treatment site in a direction generally perpendicular to the patch of skin with an exposed adhesive facing the patch of skin to be lifted and/or stretched outwardly. With the application of pressure to elastically deform the device from its original neutral configuration, the bridge portion is brought into contact with the patch of skin, adhering the skin to the adhesive. When the pressure is removed, the device rebounds and generally reassumes its original configuration with the bridge portion lifting the attached patch of skin as it returns to an elevation at or near its original elevation.
(37) With reference to
(38) Suitable materials for the body 102 include materials that are biocompatible or FDA-approved plastics, acrylate, polymers, metal, such as aluminum or stainless steel, or even wood or wood composites. A presently preferred material is polyethylene terephthalate (PET).
(39) For use of the device 200 to treat the symptoms of CTS, the thin sheet body 202 of the device has a “butterfly” configuration adapted affixation to a palm 113 of a user, as illustrated in
(40) In other embodiments, the body 202 has a thickness T ranging between about 0.012 and 0.016 inches (about 0.030 cm and 0.040 cm), and spans between about 1 inch and 1⅓ inches (about 0.0047 cm and 0.0063 cm), and preferably about 1⅕ (1.235) inches (about 0.486 cm) in the direction of the shorter/width dimension or axis W, and about 1⅘ inches and 2.0 inches (about 0.71 cm and 0.79 cm), and preferably 1 9/10 (1.900) inches (about 0.75 cm) in the direction of the longer/length dimension or axis L.
(41) The bridge portion 208 is rectangular, being elongated along the axis W and spanning about ⅜ inch (about 0.15 cm) in the L axis. Each of the side portions 220 has a rounded “petal” shape with a greater outer width 221 that tapers slightly to a lesser inner width 122 adjacent the body 208.
(42) Moreover, the body 202 is provided with at least one predetermined curvature relative to an axis to conform to contours of the palm 113 near the wrist and location of the carpal tunnel (
(43) The inner surface 206 of the bridge portion 208 is provided with an adhesion member or adhesive 226, for example, a coating or layer of adhesive for releasably affixing the device 200 to the palm. The adhesive 226 is covered and protected by a release liner 228 that is removed prior to use of the device 200 and application onto the user's skin.
(44) With reference to
(45) When the pressure P is removed and the body 202 is released, the elastically deformable body 202 generally returns to its original neutral state in reassuming the predetermined concavity and the linearity between the bridge portion 208 and the wing portions 220, with at least a portion of the skin of the recess 112 adhering to the adhesive 226, as shown in
(46) In the disclosed embodiment, the bridge portion 208 is adhered to the skin, whereas the wing portions 220 are without adhesive and are not attached but are free to move and slide relative to the skin. This freedom of movement increases comfort to the user of the device by minimizing pinching or poking that may otherwise resulting discomfort if the wing portions (or any portions thereof) were also adhered to the skin. In that regard, a layer of fabric or liner or a coating of friction reducing gel may be provided on the inner surface of the wing portions 220 to prevent chafing. However, it is understood that the adhesive and adhesion member may be applied to one or more regions on the inner surface of the body and configured to cover beyond the bridge portion, for example, all or portion(s) of each or both wing portions 220.
(47) It is understood that the bridge portion 208 need not be centered between the wing portions 220. That is, the size and/or shape of each wing portion 220 need not be equal or matching to the other. One wing may be larger, wider and/or longer than the other, as need or appropriate. There need not be symmetry about the axis L or W.
(48) In an alternative embodiment of the present invention, a device 300 to treat the symptoms of a migraine headache is illustrated in
(49) The body 302 has at least two predetermined curvatures (same or different degree of curvatures), one in the axis W (
(50) In another embodiment of the present invention for treatment of migraine symptoms, especially in the center of the forehead above the nose as illustrated in
(51) For either device 300 or 300′, inner surface 206 of the bridge portion 208 is provided with adhesion member or adhesive, which may include one or more suction cups 330 (
(52) Moreover, for either device 300 or 300′, on the inner surface 306 at or near lateral edges 344, each side support portion 320 includes a projection, such as a raised ridge 346 with a height H (
(53) It is noted that the concavity/ies of the bodies (actual or as effectuated by the ridges 346) should be of a sufficient degree such that peripheral edges, including longitudinal edges 340 and lateral edges 344 extend beyond the adhesive (e.g., adhesive coating, adhesive tape, suction cups, or micro-suction cup tape) so as to elevate the adhesive from skin and provide an initial air gap before the skin is adhered to the device (as shown in
(54) In use, the adhesive 326 is exposed and the device 300′ is placed over the target skin site with the inner surface 306 and the adhesive 326 facing the skin. The device 300 is oriented with the ridges 346 straddling the skin site so that the bridge portion 308 and the adhesive 326 is directly over the sensitive skin site. Elevated by the ridges 346, the bridge portion 308 is situated above the skin, separated by an air gap. With the device so positioned, pressure is then applied by the user (or an assistant) to the outer surface 304 of the bridge portion 208 directly above the adhesive 326 toward the skin so as to deform the bridge portion 308 (and any other portions of the body 302), bring it into contact with the skin and allow the adhesive 326 to adhere to the skin.
(55) When the pressure is removed and the body 302 is released, the elastically deformable body 302 generally returns to its original neutral state in reassuming the linearity between the bridge portion 308 and the side portions 320, thereby lifting the adhered skin and tissue and reducing compression at the site. The device can be situated around the eyes, near a temple, or above the nose on the forehead, as facilitated by the arcuate longitudinal edges 240, as shown in
(56) With reference to
(57) 1. Providing a single flat sheet 150 of suitable material;
(58) 2. Heating the sheet to smooth the sheet 150 and remove wrinkles and bends;
(59) 3. Stamping, die-cutting or otherwise cutting the sheet 150 to form the device.
(60) 4. Applying the adhesive to the inner surface of the bridge portion.
(61) The method may include forming the sheet 270 with at least one predetermined curvature.
(62) Heating the sheet may include passing the sheet 170 through a heat tunnel 151, and/or under or between heated roller(s) 152. Forming the sheet 150 with at least one predetermined curvature may include passing the sheet through heated roller(s) 154. Stamping, die-cutting or otherwise cutting the sheet into device bodies may be performed by a die set including roller 154 and a movable punch 156. The movable punch 156 may be curved to conform to the curvature of the roller 154 to simultaneously form the device body with at least one or more predetermined curvature. Applying the adhesive 326 may occur at any stage, including before, during or after stamping, die-cutting or otherwise cutting the sheet. As mentioned, the adhesive may be medical grade adhesive suitable for topical use. It may take the form of a solid coating or layer (or a plurality of adhesive lines), double-sided adhesive tape, suction cup(s) or micro-suction cup tape. Any release liner may be applied simultaneously with the application of the adhesive or afterwards.
(63) Where the device has ridges 246, the die set may have formations to stamp the ridges into the sheet, or they may be mounted after stamping. Alternatively, the method of manufacture may include applying or adhering the ridges 246 to the inner surface of the bridge portion before, during or after application of the adhesive to the inner surface.
(64) An embodiment of a machine system 160 implementing a method of manufacture and packaging of the device is illustrated in
(65) Downstream of the dispenser roller 166 is a smooth roller 168 positioned to flatten the sheet material and remove wrinkles or bumps. Downstream of the smooth roller 168 is an adhesive tape applicator roller 172 which applies double-sided adhesive tape strips 174 onto an upward surface 175 of the sheet material (which becomes the inner/skin-facing surface of the device). The tape strips 174 are mounted on the applicator roller 172 with an exposed adhesive surface 171 facing outwardly so that it contacts and affixes to the upward surface 175 of the sheet material 167 upon pressure applied by the roller 172. Release liner strips 173 are affixed to the opposing surface of the applied tape strips 174 for subsequent removal by users when applying the devices.
(66) Downstream of the applicator roller 172 is a die press 179 with upper platen 176 and lower platens 178A and 178B driven by air hydraulics assembly 180. The upper platen 176 is driven toward first lower platen 178A in a first stage operation of the die press and toward the second lower platen 178B in a second stage operation of the die press, as described below, to die cut a plurality of individual devices 10A and 10B from the sheet material 167 and the tape strips 174 affixed thereon.
(67) The lower platens 178A and 178B are supported on a carrier 182 that is adapted for translational movement in opposition directions T1 and T2 along a pathway generally transverse to the conveying pathway P. In a first stage operation (
(68) In addition to driving the die press 179 and the carrier 182, the hydraulics assembly 180 also drives support arms 185 to move the transport members 184A and 184B between at least three positions: a wait position, a load position, and an off-load position. The transport members are adapted to secure a load of devices and transport the devices from the lower platens 178A and 178B to packaging or dispensers 183 arranged on tray members 186A and 186B arranged below the lower platens in their exposed positions. As shown in
(69) The tray member 186B is supported on carrier 188B which translates the tray member 186B along direction C parallel with the conveying pathway P so that the tray member 186B can shift between different positions for efficient loading of the dispensers 184. In the illustrated embodiment, the tray member is translated between two positions: a proximal position and a distal position.
(70) It is understood that the actuation and movement of the die press 179, the carrier 182, the transport members 184A and 184B and the carriers 188 may be coordinated and synchronized with each other, as desired or appropriate for efficient operation of the machine system. For example, the upper platen 176 may be driven to engage lower platen 178A as the support arm 185B is driven to pick up devices 10B from the lower platen 178B, and as the support arm 185A is releasing devices into the dispensers 181A. A suitable system and machine for transporting work pieces is described in U.S. Pat. No. 8,230,989, entitled SHUTTLE MACHINE FOR MACHINE TOOL, the entire contents of which are hereby incorporated by reference.
(71) The spent sheet material 167 downstream of the die press 179 is drawn downstream by a servo drive rollers 190 and collected on a waste roller 192 at the second end 164 of the conveying platform 161.
(72) Another embodiment of the present invention is illustrated in
(73) With reference to
(74) In one embodiment, the outer radius r of the base 450 is 1.375 inches (about 3.50 cm), the radius R of the bridge portion 408 is 0.5 inch (about 1.27 cm), the width WA of the axial portion 462 is 0.625 inch (about 1.59 cm), and the width WB of the base 450 is 0.125 inch (about 0.32 cm). The height H of the bridge portion 408 from the base 450 is 0.1875 inch (about 0.48 cm) and the thickness of the body 402 throughout the device 10 is 0.015 inch (about 0.038 cm).
(75) The base 450 and the bridge portion 408 may each be any shape, for example, rectangular, polygonal, oval, or circular. In the illustrated embodiment, both the base and the bridge portion are circular.
(76) In use, the adhesive 426 is exposed and the device 400 is placed over the target skin site with the base generally surrounding the site and the adhesive 426 facing the skin and tissue, as shown in
(77) When the pressure is removed and the upper body 452 is released, the elastically deformable body 402 rebounds and generally returns to an elevation at or near its original elevation wherein the bridge portion 408 lifts the adhered skin and tissue and reducing compression at the site.
(78) As shown in
(79) The devices of the present invention may be worn at all times, or only a specified time periods, such as night time, during sleep. Each device may be reused so long as the adhesive is functional. If not, the device may be discarded, or new adhesive may be applied to the device over or in place of the spent adhesive. Due to the inexpensive cost of the device and its components, the device may be economically discarded as trash or for recycling.
