Abstract
Description
Technical Field
[0001] This disclosure relates to hand rehabilitation training, and more particularly to a hand rehabilitation device worn on the wearer's hand for stretching the wearer's fingers by pulling force on the back of the hand. Background Technology
[0002] Spasticity is a condition caused by various neurological disorders (cerebral palsy, multiple sclerosis, stroke, traumatic brain injury, etc.). In cases of upper limb spasticity, the fingers and wrists are in a state of persistent, involuntary flexion. Due to damage to the central nervous system, information transmitted to the muscles via motor neurons causes muscle contraction, thus hindering the voluntary extension of the fingers and wrists. In addition to the loss of motor control, sensory information sent back to the central nervous system is also frequently interrupted.
[0003] In view of this, a variety of rehabilitation devices have been proposed. For example, US Patent 9,387,110 B2 discloses a variable tension rehabilitation glove, which includes a glove body configured to accommodate the user's hand, a wristband around the wrist portion, and a plurality of tension bands that connect the distal portions of the finger portion to a movable tension device for changing the tension of the tension bands.
[0004] US Patent 5,538,488 A discloses a glove for exercising human fingers. The device includes an inner glove that houses a human hand. Finger sleeves are fixed to the inner glove to accommodate the outermost portion of each finger. Multiple spring-loaded tension cords extend along the back of the glove and are used to resist movement of the glove during hand closure (gripping). An adjustment assembly applies tension to the cords to achieve the desired resistance.
[0005] In addition, similar devices are also disclosed in the following patent documents: Chinese patents CN 110433462, CN 113975747, CN 210872803U, CN 211095754U, CN 211794500U, CN 213965028U, CN 214388673U; US patents US 5,373,585, US 5,697,103, US 7,001,352, US 7,601,130, US 8,328,744, US 8,677,514, US 9,764,190; US patent applications US 2003 / 0195093, US 2004 / 0049141, US 2022 / 0218507; and international patent application publication WO 2022 / 094736.
[0006] However, further improvements are still needed, particularly in one or more aspects such as effectiveness, ease of use, user comfort, cost, and appearance. Summary of the Invention
[0007] In view of the foregoing, the following solution is proposed in one aspect of this disclosure: A hand rehabilitation training device, comprising: The wrist component includes a wrist sleeve and one or more finger components removably connected to the wrist component. The wrist component includes a hand sleeve and one or more back-of-hand bridges, the back-of-hand bridges being movably connected to the hand sleeve via an adjustment mechanism for reversibly adjusting and fixing the proximal-distal position of the back-of-hand bridges relative to the hand sleeve. The device includes one or more flexible members that removably connect each finger component to one or more of the back-of-hand bridging members, such that the flexible members apply a pulling force to the one or more connected finger components, for example, by pulling the one or more connected finger components via the respective flexible member(s). The hand sleeve accommodates the wearer's hand and wrist, and may accommodate a portion of the wearer's forearm, exposing the wearer's fingers. It includes a reversibly openable portion for opening and closing the hand sleeve around the wearer's wrist. The openable portion has a reversible closure, specifically a zipper, for opening and closing the hand sleeve around the wearer's wrist in a distal-proximal direction. The closure is preferably located on the back of the hand side of the wrist sleeve, preferably in the dorsal-radial quadrant, which facilitates operation with the wearer's other hand.
[0008] The pulling force can be located generally in the proximal direction. Preferably, the pulling force is along one or more tendons and / or the anatomical course of these tendons(s) associated with the extension of the corresponding finger. Thus, the pulling force can assist and / or correct the extension (direction) of the finger.
[0009] Flexible components can be attached to finger parts.
[0010] The hand sleeve may include multiple finger openings to individually expose fingers, for example, protruding from the hand sleeve opening. Preferably, the hand sleeve includes a single finger opening for accommodating and exposing all fingers and, possibly, portions of the palm of the hand, for example, protruding from the hand sleeve opening. The sleeve includes a separate thumb segment, which may be used to completely enclose the thumb, but preferably includes a thumb opening to expose the wearer's thumb, for example, protruding from the thumb opening.
[0011] Exposing the wearer's fingers facilitates the wearing of finger components on the fingers, without a glove layer between them. This additionally or alternatively enhances tactile contact. It also makes wearing the hand sleeves and the entire device easier, as the hand sleeves and finger components can be worn separately. The number of finger components to be connected can be selected as needed.
[0012] The hand sleeve and finger components can be sized separately. The hand sleeve can be used as a hand and / or wrist support without finger components.
[0013] For four fingers on one hand, a single bridge is sufficient. The thumb can be considered separately.
[0014] The device allows for closure by moving from the distal to the proximal end of the hand wearing the sleeve towards the wearer's body (e.g., pulling a zipper pull or another closure element), which aligns with the natural movement of wearing the device, allowing the wearer to at least wear the sleeve without assistance. This also applies to reverse operation and adjustments to open the closure and remove the sleeve.
[0015] The hand sleeve may have reversibly closable or non-openable portions for encircling the hand, such as one or more finger openings with a closing perimeter and / or a thumb opening with a closing perimeter, which may be permanently closed. Additionally or alternatively, the hand sleeve may include a blind end (preferably a distal blind end) relative to the reversible closure, such as the end of a zipper, which may be closed or even permanently closed.
[0016] This device allows the hand sleeve to open and close in the proximal-distal direction.
[0017] The device can be opened and closed by allowing movement from proximal to distal and / or from distal to proximal, thereby allowing the hand sleeve to open and close in the proximal-distal direction. The device can also allow closure, for example by means of a zipper, in the same and / or opposite direction to the opening direction.
[0018] The device allows the opening and closing of the hand sleeve by including an opening oriented in a proximal-distal direction, and can be reversibly closed by one or more closing members. The closing members can be oriented relative to the opening such that the closing members allow the opening to be reversibly closed and opened by closing and / or opening actions. The closing and / or opening actions can be parallel to the opening itself, thus proceeding in a proximal-distal direction.
[0019] Additionally or alternatively, the device may include a closure member oriented relative to the opening, such that the closure member allows the opening to reversibly close and / or open in a direction transverse to the opening direction (and thus in a direction transverse to the proximal-distal direction).
[0020] Alternatively or additionally, the closing member may be oriented in a different direction relative to the opening.
[0021] The device may include two or more closing members for reversibly closing and opening the hand sleeve. At least two closing members may be oriented relative to each other in a proximal-distal direction. This allows the device to be opened and closed in the proximal-distal direction by subsequently opening and / or closing the hand sleeve using at least two closing members.
[0022] This can aid in wearing the sleeve, for example, reducing the risk of slippage and / or rotation around the hand, and / or preventing such risks. It has been found that the combination of a closure portion for encircling the hand and an openable portion for encircling the wrist and possibly the thumb greatly facilitates the wearer's use of the device without assistance. Furthermore, a closure with a blind end can provide a starting point for the closure and / or requires less force to pull the two sides of the opening together and / or attach them compared to a structure where two free ends must pull against each other to close.
[0023] Additionally or alternatively, in connection with the foregoing disclosure, a hand rehabilitation training device is also provided, comprising a wrist component and one or more finger components removably connected to the wrist component. The wrist component includes a hand sleeve and one or more back-of-hand bridging members, the back-of-hand bridging members being movably connected to the hand sleeve via an adjustment mechanism for reversibly adjusting and fixing the proximal-distal position of the bridging members relative to the hand sleeve. The hand sleeve accommodates the wearer's hand and wrist, exposing the wearer's fingers. The device includes one or more flexible members that removably connect each finger component to one or more of the back-of-hand bridging members, such that the flexible members apply tension to the one or more connected finger components. In particular, hand rehabilitation training devices according to any embodiment of the device disclosed herein, wherein a hand sleeve accommodates the wearer's hand and wrist, exposing the wearer's fingers, and wherein one or more finger components each include a fingertip portion (distal phalanx) attached around the fingertip and a finger root segment for attachment around the finger root portion (proximal phalanx), wherein at least one of the fingertip portion and the finger root portion is relatively soft and bendable, and may be relatively elastic, for example, typically made of one or more padded or unpadded textile fabrics, and wherein one or more finger components each include a relatively rigid support ridge connected to the fingertip portion and the finger root portion and configured to be placed on the middle phalanx of the wearer's finger and along the middle phalanx in a back-of-hand position.
[0024] The fingertip and the base of the finger can be one piece, for example, at least partially formed from a single piece of fabric.
[0025] The relatively soft and flexible portions, as well as potentially relatively elastic portions, may be made, for example, typically of textile fabrics (e.g., at least partially knitted and / or crocheted fabrics), although woven and / or nonwoven fabrics (including leather) may also be used. The finger components may comprise different portions of (mostly) different materials, such as different fabrics. An elastic sheet may be used additionally or alternatively. This material may be at least partially "breathable" and / or water-permeable, and preferably designed for prolonged contact with the skin. The finger components may include padding in one or more portions. The relatively soft, flexible, and potentially elastic portions(one or more) of the finger components allow free movement of the hand and / or wrist, preferably with minimal obstruction, such as very soft clothing or knitted gloves.
[0026] The functions of a relatively rigid support ridge include, but are not limited to: attaching one or more flexible elements associated with the finger portion, guiding the flexible elements to the finger and / or palm, distributing tension and / or pressure on the finger and / or finger components, and assisting in the fixation of the finger components on the finger.
[0027] The support ridge can typically be flexural or allow a certain degree of flexure, and its flexibility can be selected based on the length of the support ridge relative to the middle phalanx. The support ridge can be formed from any suitable material (e.g., plastic, metal, leather, rubber, etc.). The support ridge preferably comprises a thermoplastic material designed to deform when heated above ambient temperature to conform to the wearer's anatomy, and to maintain its deformed shape when cooled to ambient temperature, thus facilitating at least a portion of the support ridge to conform to the wearer's anatomy and / or defining a specific range of motion for the finger.
[0028] The flexible component can be attached (e.g., removably attached) to a support ridge, preferably at a position corresponding to the middle of the middle phalanx of the wearer's finger or proximal to the support ridge. The support ridge can help guide the direction of tension. This can achieve one or more of the following effects: facilitating the connection, positioning, and / or orientation of the flexible component to the finger components, and improving wearer comfort.
[0029] The support ridge may include one or more openings for accommodating one or more interphalangeal joints. Preferably, the support ridge includes a distal opening and a proximal opening, respectively associated with the distal and proximal interphalangeal joints. This can facilitate finger flexion, which can achieve one or more of the following effects: positioning and / or orienting the support ridge and any attached parts (e.g., flexible members, soft and bendable parts) and the finger components as a whole, improving wearer comfort.
[0030] Additionally or alternatively, in connection with the foregoing disclosure, a hand rehabilitation training device is also provided, comprising a wrist component and one or more finger components removably connected to the wrist component. The wrist component includes a hand sleeve and one or more back-of-the-hand bridging members, the back-of-the-hand bridging members being movably connected to the hand sleeve via an adjustment mechanism for reversibly adjusting and fixing the proximal-distal position of the bridging members relative to the hand sleeve. The hand sleeve accommodates the wearer's hand and wrist, exposing the wearer's fingers. The device includes a flexible member that removably connects each finger component to the one or more back-of-the-hand bridging members, such that the flexible member applies tension to the one or more connected finger components. The device is particularly rooted in… The hand rehabilitation training device according to any embodiment of the device disclosed herein, wherein the hand sleeve accommodates the wearer's hand and wrist, exposes the wearer's fingers, and wherein one or more finger components may include a fingertip portion and / or a finger root portion, the fingertip portion including a sleeve and / or annular portion for accommodating, for example, the fingertip (distal phalanx) surrounding the wearer's finger, and the finger root portion including an annular portion for surrounding the base segment of the wearer's finger (proximal phalanx), wherein the fingertip portion and the finger root portion are separate and spaced apart from each other on the palm side of the device, for example leaving space for exposing at least a portion of the middle phalanx of the wearer's finger, so that tactile sensation is minimally or unimpaired, thereby facilitating use and possible rehabilitation training.
[0031] In any embodiment, one or more of the following schemes may be advantageously employed.
[0032] At least a portion of the hand sleeve may be relatively soft and flexible, and may be relatively elastic, for example, typically made of textile fabric (e.g., at least partially knitted and / or crocheted fabric), although woven and / or nonwoven fabrics (including leather) may also be used. The hand sleeve may include different portions of (mostly) different materials, such as different fabrics. An elastic sheet may be used additionally or alternatively. This material may be at least partially "breathable" and / or water-permeable, and preferably in long-term contact with the skin. The hand sleeve may include one or more padded portions. The relatively soft, flexible, and possibly elastic portions (one or more) of the hand sleeve allow free movement of the hand and / or wrist, preferably with substantially no obstruction, for example, very similar to clothing. The same materials and related considerations also apply to one or more of the finger components, see also below.
[0033] The hand sleeve may include a relatively rigid support. The support is configured to generally impede or even prevent wrist and / or hand movement. The support may include palm support legs and / or back support legs for extending across the wrist in a proximal-distal direction (e.g., across the carpal bones), for example, from the overlap with the arm bones (radius, ulna) to the overlap with the palm of the hand (preferably: most or all of the metacarpal bones). Thus, it may, for example, support and / or stabilize the position and / or range of motion of the wearer's hand, and / or provide a basis for applying tension to the fingers.
[0034] The hand sleeve and the support may be integrated, or may be non-detachable, but preferably the support is removably attached to the hand sleeve, for example, the hand sleeve may include a pocket that accommodates at least part of the support.
[0035] The support may include palm support legs and back support legs connected by a back, which stabilizes the palm support legs and back support legs. The support preferably does not have another back, which can facilitate adjustment of the size of the hand sleeve and / or the support and / or facilitate wearing the support and / or the hand sleeve. The back may be a ulnar back, extending beyond the ulnar back of the hand, and particularly and preferably without radial connection between the palm support legs and the back support legs. This facilitates free movement of the thumb and / or prevents a feeling of bulkiness and / or pressure on the hand between the thumb and index finger. The back may include a distal groove that is associated with the lateral abduction of the wearer's fingers adjacent to the back (e.g., ulnar abduction of the little finger where the ulnar back allows finger spread). The support may be M-shaped, at least in the spread configuration, to facilitate lateral abduction while maintaining the rigidity of the support, for example, by keeping the dimensions (e.g., width and thickness) constant along the shape of the support.
[0036] The stent can be formed to conform to the wearer's body structure, for example, based on fingerprints, models, and / or (3D) scans of the wearer's hand. At least a portion of the stent can be manufactured using additive manufacturing processes. At least a portion can be made of metal and / or plastic materials. The device can be configured to be adjustable to conform the stent to the wearer's body structure, for example, to optimize operability and / or wearer comfort, which contributes to one or more of usability, therapeutic effectiveness, and acceptability. In particular, the stent may include a thermoplastic material for deforming the stent to conform to the wearer's body structure when heated to above ambient temperature, and retaining the deformed shape when cooled to ambient temperature, facilitating conformation to the wearer's body structure and / or facilitating the determination of a predetermined range of motion for the hand and / or wrist.
[0037] Additionally or alternatively, the device may also include a releaseable and / or openable wristband for reversibly tightening and loosening a loop around the wearer's wrist and / or forearm, and / or for reversibly wrapping and closing the loop around the wearer's wrist and / or forearm from an open position, and reversibly opening the loop from a closed position and releasing the loop from the wearer's wrist and / or forearm, respectively. The wristband may assist in holding a wrist sleeve and / or support (if provided) in a desired position relative to one or more of the wearer's wrist, forearm, and hand. Additionally or alternatively, for example, the location and / or range of motion and / or base for applying tension to the fingers may be provided. Additionally or alternatively, the wristband may secure a reversible closure, and the wristband may cross and / or overlap.
[0038] The adjustment mechanism of at least one back-of-hand bridging member may include a rotary adjustment handle, such as a rotary button. Rotation may allow (continuous or stepwise) adjustment and / or locking of the rotary button to define continuous and / or stepwise positional adjustment of the bridging member. The rotary button may have a fastening mechanism by rotation, such as for winding a flexible adjustment member (e.g., a cord or strap) through which the bridging member can be connected to the adjustment handle. The adjustment mechanism may have a release mechanism. The release mechanism may preferably be operated by a movement other than rotation, such as by axially moving at least a portion of the handle (e.g., the button) relative to the axis of rotation of the rotary adjustment handle, which facilitates the operation and / or construction of the adjustment mechanism and / or can prevent maloperation of the adjustment mechanism. Such rotary adjustment mechanisms and buttons are well known and have been widely commercialized, and therefore will not be described further herein.
[0039] Rotation facilitates one-handed operation, and / or facilitates the retraction of the flexible adjustment member, and / or facilitates maintaining substantially the dimensions associated with the adjustment mechanism, and / or facilitates providing a relatively large stroke for the bridging member without disassembly. Reasonable and predictable dimensions can be provided.
[0040] The flexible member can be elastic and / or allow for reversible length adjustment between the finger component and the bridging member, preferably at least at the distal end of the bridging member. This can help regulate the tension between the bridging member and the finger component connected by the flexible member.
[0041] The device may include a thumb segment removably attached to a hand sleeve. The thumb segment and hand sleeve can be configured to reversibly adjust and fix the proximal-distal position of the thumb relative to the hand sleeve, applying a pull force to provide an adjustable pull (e.g., pulling the thumb segment). The thumb segment preferably may have a flexible component, like a finger / finger component. Regarding the finger, the pull force may be set along the anatomical course of one or more tendons and / or tendons associated with thumb extension. Therefore, the pull force can assist and / or correct thumb extension (direction).
[0042] Therefore, the thumb can also be pulled, possibly not connected to the bridging element and / or by providing a separate bridging element and / or a separate adjustment device. Thus, the direction of pull on the thumb can differ from the overall direction of pull on the fingers; the flexible components of the fingers can be arranged on at least a portion of the back of the hand, generally parallel to the respective fingers, while for the thumb, the direction of pull is preferably radial, rather than generally back-of-the-hand.
[0043] One or more finger components may include a loop portion that accommodates (e.g., wraps around) the wearer's finger. This loop is operable for reversibly wrapping and closing the loop around the wearer's finger, and for opening and unwrapping the loop from the wearer's finger, respectively. For example, one or more finger components may include a fingertip portion and / or a base portion. The fingertip portion includes a sleeve and / or loop portion that accommodates, for example, the fingertip of the wearer's finger, and the base portion includes a loop portion that wraps around the base segment (proximal phalanx) of the wearer's finger. One or each of the loops may be operable for reversibly wrapping and closing the loop around the wearer's finger, and for opening and unwrapping the loop from the wearer's finger, respectively.
[0044] This can facilitate wearing the finger component, and thus the entire device. The opening and closing of the rings avoids the need to insert the finger into the finger component (which can be painful or virtually impossible for spastic or curled fingers).
[0045] At least a portion of the finger component (particularly the fingertip) can be formed of a touchscreen-sensitive material. Therefore, the wearer can operate the touchscreen while wearing the device (the finger component). It should be noted that the exposed finger portion can also allow or assist in touchscreen operation.
[0046] Therefore, as will be further explained below, the hand rehabilitation training device provided in this disclosure can simultaneously function as a dynamic splint and a pressure wrist sleeve. The dynamic splint may be responsible for counteracting wrist and finger contractions while still allowing a certain degree of movement. The function of the pressure wrist sleeve, combined with the open design of the device, can be used to promote blood flow, thereby improving sensory feedback. Attached Figure Description

[0057] It should be noted that the accompanying drawings are schematic and not necessarily drawn to scale, and unnecessary details have been omitted for ease of understanding of the invention. Unless otherwise stated, terms such as "up," "down," "below," and "above" refer to the orientation of the embodiments shown in the accompanying drawings. Furthermore, elements that are at least substantially the same or perform at least substantially the same function are labeled with the same reference numerals; for ease of distinction, letter suffixes may be used in different embodiments and / or the reference numerals may be increased by values such as 100 or 200.
[0058] [Furthermore, unless otherwise stated, terms such as "openable," "detachable," and "removably connected" refer to the ability of the corresponding parts to be opened and / or disconnected individually without substantially causing damage or destruction to one or more of the related parts; for example, such terms do not include structures where the parts are integral (such as continuous segments of the same component, welded together, or molded together), but do include structures where the parts are connected by mating connectors, fasteners, releasable self-fastening structures, etc. The verb "to cause" means "to make easier and / or simpler," not "to make possible."]
[0059] Figures 1-2 An embodiment of a hand rehabilitation training device 1 (of its components) is shown, comprising a wrist component 3 and one or more finger components 5 removably connected to the wrist component 3. The wrist component 3 includes a hand sleeve 7 and a back-of-hand bridging member 9. The device 1 also includes flexible members 11, each flexible member 11 removably connecting a finger component 5 to the back-of-hand bridging member 9 via a hook 10 or other connector. In other embodiments, one or more bridging members may be provided, and / or one or more bridging members may be formed differently, for example, molded as a single unit. In this document, the flexible members 11 associated with all four finger components 5 / all four fingers are attached to the same bridging member 9; however, one or more finger components 5 may be omitted.
[0060] The back-of-hand bridging member 9 is movably connected to the hand sleeve 7 via an adjustment mechanism 13, which includes one or more flexible adjustment members 15 (e.g., one or more straps or cords) and an adjustment handle 17 (in the form of a rotary button herein). The adjustment mechanism 13 is configured to reversibly adjust and fix the proximal-distal position of the bridging member 9 relative to the hand sleeve 7 by rolling up / rewinding a portion of the flexible adjustment member 15. Thus, when the device 1 is worn on the hand and arm of a wearer (not shown), a reversible tightening mechanism is provided to apply tension to one or more connected finger parts 5 worn on the wearer's fingers (not shown) by the flexible member(s) 11. The adjustment member 15 may be held by an optional ring 19 or other structure to prevent it from being caught on an object. The bridging member can attach a single adjustment member 17 to one adjustment handle 17, or multiple adjustment mechanisms 13 to multiple adjustment handles 17.
[0061] The hand sleeve 7 accommodates the wearer's hand and wrist (not shown), exposing the wearer's fingers (not shown). The distal end 7D of the hand sleeve 7 includes a non-openable sleeve portion that provides an opening 21 for encircling the hand. In another embodiment, the distal end 7D may be reversibly openable (not shown). The hand sleeve 7 also includes an optional thumb sleeve 23 and a thumb component 25 (only when...). Figure 1As shown in the figure, the thumb component 25 (hereinafter referred to by a flexible member 27) is removably connected to the hand sleeve 7, the flexible member 27 being connected by a hook 29 to a ring 31 disposed on the hand sleeve 7. The distal end of the thumb sleeve 23 includes a non-openable portion having an opening 33 surrounding the thumb.
[0062] The hand sleeve 7 includes a zipper 35 in the proximal-distal direction, the zipper 35 having a reversibly openable portion for opening and closing the proximal end 7P of the hand sleeve 7 surrounding the wearer's wrist. The zipper 35 has a blind end that closes at the distal end 33D.
[0063] At least a portion of the hand sleeve 7 is relatively soft and flexible, and may be relatively elastic, for example, typically made of one or more padded or unpadded textile fabrics, and the hand sleeve 7 includes a relatively rigid support 36 (discussed further below). The hand sleeve 7 may be configured to fit snugly around the wearer's hand, wrist, and forearm (distal portion) (not shown); the hand sleeve 7 may generally be elastic to engage with the wearer's body with a substantially constant local pressure along and substantially through the sleeve 7, thereby preventing localized stress and / or obstruction of blood flow.
[0064] Device 1 also includes one or more optional openable wristbands 37 for reversibly wrapping and closing the loop around the wearer's wrist and / or forearm, and for opening and unwrapping the loop from the wearer's wrist and / or forearm, respectively. The wristband 37 is preferably positioned proximally on the wrist component, configured to attach below the wearer's wrist bone for maximum support. The wristband 37 is preferably secured to a wrist sleeve (not shown) and includes optional eyelets 39 through which the free front end of the wristband 37 passes and folds back to the tail end of the wristband 37. This can facilitate tightening the band 37. The band 37 may have a releasable closure, such as a buckle and / or hook-and-loop fabric fastening system (e.g., Velcro is preferably preferred). The wristband 37 can be tightened by the adjusting member 15 to prevent interference with the adjusting member 15 (tension control adjusting member 15). The wristband 37 is also preferably configured to be detachable from the adjusting handle 17.
[0065] Each finger component 5 (as shown) includes a relatively soft and flexible portion 41, which may be relatively elastic, for example, typically made of one or more padded or unpadded textile fabrics, for attachment around the wearer's finger (not shown). The soft finger component portion 41 includes a fingertip portion 43 for attachment around the fingertip (including a sleeve) of the wearer's finger (not shown), and a finger base portion 45 for attachment around the base segment of the wearer's finger. The finger base portion 45 includes a band 47 for reversibly wrapping around the wearer's finger base (proximal) segment to form a closed loop, and for opening and unwinding the loop from the wearer's finger.
[0066] Each finger component 5 (as shown) includes a relatively rigid support ridge 49 attached to the back-of-hand side of the flexible finger component portion 41. The support ridge 49 is configured to lie on and along the middle phalanx of the corresponding wearer's finger (not shown) in a back-of-hand position. The support ridge 49 includes an opening 51 accommodating the flexion and extension of the corresponding interphalangeal joint, which may be formed in and / or through a rigid material (as shown) of the support ridge 49. One or more of these openings 51 may expose the flexible finger component portion 41 beneath the support ridge 49, or may be open and expose the finger. The support ridge 49 may be formed of any suitable material (e.g., plastic, metal, rubber, hard leather, etc.). In another embodiment (not shown), one or more support ridges 49 may be covered by, integrally formed with, and at least partially accommodated within the flexible finger component portion 41.
[0067] In each finger component 5 (as shown), the fingertip portion 43 and the finger root portion 45 (47) are separated and spaced apart from each other on the palm side of the device, leaving space S to expose at least a portion of the middle phalanx of the wearer's finger.
[0068] Figure 2 , Figures 4-5 Embodiments of brackets 36 and 236 are shown. Figure 5 It shows the unfolded state. Figure 2 The support 36 is generally M-shaped. In its unfolded state, the support can be flat; for example, it can be cut from metal or thermoplastic sheet. Other manufacturing methods are also available. Figure 2 and Figure 4 The brackets 36 and 236 in use are shown, configured to operatively fit around the wearer's hand, such that the brackets include palmar support legs 53 and 253 and dorsum support legs 55 and 255 connected via ulnar dorsal sides 57 and 257, to fit around the ulnar side of the wearer's hand (not shown). Because bracket 36 is M-shaped, Figure 2 and Figure 5 The back 57 is typically V-shaped and provides a distal groove 59 for the wearer's fingers (in this context, the little finger) adjacent to the back to extend laterally outward. Figure 5 As shown, the distal portions of the back-of-hand side (DD) and the palm-side (DP) can be the same or different to accommodate the movements shown; the support (as shown) can be bent and deformed from... Figure 5 As shown in the unfolded geometry, the support legs 53 and 55 appear to bend "towards the observer".
[0069] Figure 4 The support 236 can be roughly U-shaped (not shown) in its unfolded form, so that the ulnar back can unfold laterally outward as shown in the figure when it is formed to fit the wearer's hand operablely.
[0070] Figure 3 (= Figure 3 A- Figure 3 E) is a schematic diagram of the finger component 105 of the hand rehabilitation training device described herein in different directions. In this embodiment, the support ridge 149 has a distal extension 49D that provides a cap 43 on the soft fingertip portion 141. A flexible member 111 is attached to the middle portion of the support ridge 149.
[0071] Different embodiments of finger components 5, 105 and / or other components (not shown) can be combined with a wrist component (e.g. Figures 1-2 Used together with wrist parts, for example, in connection with different (degrees) of injury to different fingers.
[0072] The preferred embodiment of the provided device features a combination of soft and hard materials in the finger and wrist components. The finger components can be clipped / sleeved individually, allowing for independent use. Simultaneously, the finger components have (elastic) tensioners (e.g., at their proximal end) and can be largely positionally adjustable via continuous tensioners. The wrist component comprises a rigid support and can be slidably fitted. Unlike conventional rehabilitation devices, this device can be easily personalized through the number of tensioners, wrist sleeves, and fingers. Furthermore, the device is lightweight, compact, and can be used independently in a home environment.
[0073] The device provided includes several individual components that work together to open the wearer's wrist and fingers into a functional position.
[0074] The wrist brace can be made of a thermoplastic material that can be molded (e.g., shaped) to conform to the wearer's body structure. Furthermore, the thickness of the component can be selected based on the required strength (e.g., related to the severity of the wearer's spasticity). This brace can be configured to hold the wrist in a neutral position, thereby helping to relieve spasticity and involuntary movements. An optional adjustable wristband can be wrapped around the forearm to stabilize the wrist component. The band can be closed with any suitable closure device; as noted, a hook-and-loop fabric fastening system (such as Velcro) may be preferred; when closed, the front end of the preferred band is preferably passed through the eyelet and folded back (e.g., closed to the end of the band), pulling the eyelet to reduce the force required for closure and / or provide an anchoring point for the closure.
[0075] The device also includes one or more individual finger components. These components are preferably made of semi-rigid plastic on the back of the finger and attached to an elastic material. Each finger component can be individual to make it easier for the wearer (potentially the wearer themselves without assistance) to put one or more finger components on the finger. Furthermore, the number of fingers affected by spasticity may vary, and therefore the number of finger components used may also vary, thus constituting another layer of personalization.
[0076] The finger components help extend the fingers while still allowing for grasping, picking up, everyday activities, and other finger movements. This is achieved through the flexible materials of the finger components and the rigid materials that conform to the finger bones.
[0077] The finger and wrist components are preferably attached together via two adjustable mechanisms (e.g., hooks). These mechanisms can be continuously adjustable. The first adjustable mechanism is attached to the finger component (e.g., its proximal end and / or rigid portion (also referred to as the "support ridge")) and is made of a flexible material (possibly elastic) with an adjusting member. The adjusting member may include a slider that allows continuous sliding and / or can be configured to adjust to discrete positions. A connector (preferably a hook, which attaches to a bridging member in use) may be provided at one end of this member. The second adjusting mechanism may also be continuously adjustable or adjustable to discrete increments, and / or this mechanism may include a rotary button or "wheel" attached to the wrist component (particularly to the support). This wheel is also attached to the bridging member, preferably connected via a flexible adjusting element (e.g., a cord), more preferably having much lower elasticity than a flexible band, such as very little or virtually no elasticity. This wheel can be easily adjusted with one hand and can withstand a greater tightening range than a flexible band. It should be noted that more or fewer mechanisms can be provided.
[0078] The device can also provide compression feedback. Compression provided by the wrist component (particularly the wrist sleeve) (potentially assisted by an optional brace) can stabilize the hand and reduce tremors and involuntary movements. In this respect, the wrist component can also be used by people with Parkinson's disease or arthritis. In this case, the wrist component can be provided separately rather than as part of the device, and the back-of-hand bridging and adjustment mechanisms can be optionally omitted.
[0079] In a preferred embodiment, the flexible wrist sleeve covers a portion of the palm and back of the hand, a portion of the wrist and forearm (e.g., extending downwards approximately halfway down the forearm), and also includes an optional thumb sleeve. An optional pocket may be provided within the flexible compression wrist sleeve to accommodate (e.g., slide in) at least a portion of the wrist support (if provided). The flexible compression wrist sleeve can be closed, for example, by zipping it up with one hand; the hand and thumb sleeves can hold the sleeve in place against pull on the zipper and facilitate closure.
[0080] The preferred finger components are also made of a soft, compressible material with a semi-rigid plastic support ridge attached. The finger components may include small fingertip components into which the fingers are inserted. The fingertip components may be made of a touchscreen-sensitive material. A strap is provided at the proximal end of the finger component (e.g., at the proximal segment of the finger), which can be adjusted to the size of the finger and allows the finger component to be easily and individually worn. Except for the fingertips and base, most of the palm base of the hand is preferably open to allow for maximum sensory feedback. Parts exposing the palm and fingers, as well as optional textured surfaces on the wrist components, enhance grip and dexterity, making it easier to grasp objects and perform fine motor tasks.
[0081] Figure 6 An alternative embodiment of the hand rehabilitation training device 1 is shown, including a wrist component 3, with one or more finger components 5 removably connected to the wrist component 3. Figure 1 The parts in the illustrated embodiment have the same reference numerals. The wrist component 3 includes a hand sleeve 7 and a back-of-hand bridging member 9. The hand sleeve 7 includes a multi-layered component that is generally concave to accommodate the hand and wrist. It can also be a single-layered component.
[0082] Multi-layer components comprise multiple layers and can be formed from semi-rigid materials such as TPU or another type of semi-rigid material, maintaining their general shape during normal use while allowing the wearer's hand to bend. The layers on the palm surface of the multi-layer component, facing the back of the wearer's hand, can have properties that prevent sweating and irritation, and prevent slippage. The stiffness and shape of the multi-layer component depend on the specific application. For example, if wrist support or stabilization is required, the multi-layer component can be more rigid. Multiple layers can improve wearer comfort; for example, the layer in contact with the skin can be made of a soft material that transfers sweat and heat, and this layer can provide a grip that helps the hand sleeve 7 stay in place.
[0083] The back-of-hand bridging member 9 is movably connected to the hand sleeve 7 via an adjustment mechanism 13, which includes one or more flexible adjustment members 15 (e.g., one or more straps or cords) and an adjustment handle 17 (in the form of a rotary button herein). The adjustment mechanism 13 is configured to reversibly adjust and fix the proximal-distal position of the bridging member 9 relative to the hand sleeve 7 by rolling up / rewinding into part of the flexible adjustment member 15.
[0084] The hand sleeve 7 includes two reversibly closable wristbands 37. Each wristband 37 may have a permanent connection end and a loose end, the permanent connection end being directly or indirectly connected to the multi-layer component and reversibly closing in two steps.
[0085] In the first closing step, the movable end of the wristband 37 can be removably connected to the multi-layer component via the first fastening member 67, surrounding the wearer's hand, wrist, and / or forearm. Figure 6 In this process, the first fastening member 67 may include a hook-and-loop fastener, but may also be made of other types of fasteners.
[0086] The two first fastening members 67 of the corresponding wristband 37 are located in the proximal-distal direction relative to each other.
[0087] In the second step, the wristbands 37 can be tightened. In this embodiment, each wristband 37 includes a second fastening member ( Figure 6 (Not shown in the image). The wristband 37 includes a section made of a flexible material having a hook-and-loop fastener. The flexible material is received through a groove in the wristband 37 and folds back onto itself, such that the hook-shaped section of the fastener on the wristband 37 connects to the annular section of the fastener on the wristband 37, or vice versa.
[0088] The wristband 37 can be positioned around the wearer's hand, wrist, and / or forearm.
[0089] The wristband 37 may include sections of a material with elastic properties (such as elastic fabric) to enhance wearer comfort. The elastic material can prevent or limit high forces on the wearer's hands, arms, and / or wrists.
[0090] The two-step method is advantageous for those who lack sufficient strength to position the wristband 37 as desired and tighten it simultaneously. The wearer can first easily position and attach the wristband 37 to the multi-layer component via the first fastening member 67 in the first step, and then tighten the wristband 37 via the second fastening member 67.
[0091] The hand sleeve 7 can be opened by releasing the first and / or second fastening member.
[0092] The hand sleeve 7 includes guide members 38 located on the back side of the hand sleeve 7. The guide members 38 can guide the finger parts 5 and / or flexible members 11 in the longitudinal direction of the wearer's fingers. The guide members 38 can help retain the finger parts 5 around the fingers during use. They can also help guide tension in the finger parts 5. The guide members 38 can be made of plastic, metal, wood, or other suitable materials. In this case, the finger parts 5 are flexible, elongated elements, but in alternative embodiments, they can have different properties and dimensions.
[0093] A strip 40 is provided on the back side of the hand sleeve 7. The strip 40 can be made of a flexible material and allows the guide component 38 to be (re)positioned in the lateral direction of the fingers. This makes the device customizable to suit, for example, different hand sizes, various usage situations, and various diseases or injuries.
[0094] Similar to Figures 1-2 In one embodiment, the back-of-hand bridging member 9 and the adjustment mechanism 13 are configured to provide an adjustable pulling force to one or more of the finger components 5. Figure 9 Different sides of an alternative embodiment of the back-of-hand bridging member 9 are shown. It includes a slot 41 for receiving a flexible member 11. The slot 41 has a toothed inner surface to secure the flexible member 11 to the back-of-hand bridging member 9. A tiltable closure member 42 can close the slot 41.
[0095] The finger component 5 is connected to the back-of-hand bridge component 9 via a corresponding flexible member 11. The finger component 5 may be at least partially made of a soft and flexible material (e.g., fabric). The finger component 5 allows the finger to bend through elastic deformation.
[0096] The finger component 5 includes a section 60 with increased stiffness. Figure 6In the middle section, the increased stiffness of segment 60 extends along the anatomical course of the flexor tendons of the fingers, as they begin in the center of the finger and extend distally, thus reducing pressure on the proximal interphalangeal joints when the finger is in a flexed position. In such a case... Figure 6 In the illustrated embodiment, each finger component 60 has two segments 60 forming a V-shape. The segments 60 are more rigid than the finger component 5. They can be fixed to the finger component 5 by sewing, gluing, or the like. The outward expansion of the rigid segments 60 can advantageously influence the direction of the pulling force because it can provide a centering effect on the force, which can help keep the finger straight and limit lateral movement of the finger.
[0097] The thumb component 25 is attached to one of the wristbands 37. Alternatively or additionally, the thumb component 25 may be removably attached to the multi-layered components of the hand sleeve 7. The device can also be used without the thumb component 25.
[0098] The thumb component 25 has a separate tension system. Figure 6 In one embodiment, the tension system is a trapezoidal (H-shaped) latch 62. Similar to the finger component 5, the thumb component 25 also includes a section 60 with increased stiffness.
[0099] Figure 7 One of a finger component 5 including segment 60 and a thumb component 25 including segment 60 is shown. In this case, the thumb component 25 is also an elongated element, but in alternative embodiments it may have different sizes and shapes.
[0100] The hand sleeve 7 may have a palm portion 63, such as Figure 8 As shown. In this configuration, each wristband 37 is indirectly connected to the multi-layered components of the hand sleeve 7 via a palm portion 63. The palm portion 63 is movably connected to the hand sleeve 7 via flexible connectors in the form of three straps 64, which fold around the wearer's hand so that the palm portion 63 is positioned within the wearer's palm. The palm portion 63 can support the wrist to hold it at a desired angle. The palm portion 63 can be slightly curved and can be formed of a semi-rigid material. The palm portion 63 connects the wristband 37 to the hand sleeve 7 via the three straps 64 and wraps around the hand, wrist, and / or forearm.
[0101] The palm portion 63 can be configured to facilitate the movement of the wearer's fingers. The palm portion 63 can provide support and grip to hold the hand sleeve 7 in the desired position.
[0102] Figure 8The wristband 37 is shown passing through a corresponding elongated through-hole 65 in the palm portion 63. The end of each wristband 37 passing through the corresponding through-hole can be secured to the remainder of the wristband 37 by folding it back over, for example, by a well-known hook-and-loop attachment. This can be considered the second fastening member 66 mentioned above. The other end of the wristband 37 can be considered the first fastening member 67, see [link to previous section]. Figure 6 The wristband 37 is configured to close the hand sleeve 7 around the wearer's wrist in two steps. The multi-layered components of the wristband 37 and hand sleeve 7 have a first fastening member 67 and a second fastening member 66. The first fastening member 67 is used to fasten the wristband to the hand sleeve 7 in a first relative position (mutual position) in the first step, and the second fastening member 66 is used to fasten the wristband 37 to the multi-layered components of the hand sleeve 7 in a second step. The hand sleeve 7 wraps around the wearer's wrist more tightly in the second relative position than in the first relative position.
[0103] With the palm portion 63 omitted, the wristband 37 is directly connected to the multi-layered component of the hand sleeve 7. If a two-step fastening is required, a through hole similar to the through hole in the palm portion 63 can be provided in the multi-layered component of the hand sleeve 7.
[0104] Furthermore, the wrist component's hand sleeve applies gentle pressure to the affected hand, promoting muscle relaxation and reducing spasms. Therefore, the device facilitates a more comfortable hand and wrist position, thereby improving functional abilities, encouraging independence, and enhancing the quality of life for individuals with neurological disorders.
[0105] This disclosure is not limited to the embodiments described above, which may be varied in many ways within the scope of the claims. For example, in at least some embodiments: a. The device is designed to be available in various sizes and adjustable to fit each wearer's body individually, allowing for near-complete personalization and optimal comfort. Soft wrist and finger components can be in standard sizes. At least a portion of the wrist component (particularly the support) can be molded / adjusted to fit the precise dimensions of an individual's hand; b. The device may be available in several different sizes and multiple size options (e.g., for wrist and finger components); and may have one or more adjustable components that are attached to the wrist component and configured to adjust the size of one or more of the components to fit each patient’s body.
[0106] c. Several adjustable components are attached to the wrist component and configured to secure the device to the patient's body. The device can be designed to allow the patient to wear and use it independently without assistance.
[0107] d. Provides soft, flexible sleeves or gloves (i.e., fingerless gloves) that cover the hand (excluding most of the palm), wrist, and half of the forearm.
[0108] i. The soft parts may be made of elastic materials, such as spandex, neoprene, Lycra, polyurethane, nylon, polyester or similar materials.
[0109] ii. The soft part has a closure mechanism, which may be in the form of a zipper, button, tightening wheel, shoelace, Velcro, or hook.
[0110] e. A support made of moldable semi-rigid plastic that can slide into an optional pocket of a soft component molded by a therapist or end-user. Such a moldable support can also be made of metal or other types of plastic.
[0111] f. Optional reversibly openable and closed strap for wrapping around the wrist and preventing movement of the brace or other rigid components, including one or more of buttons, buckles, ties, hook-and-loop fasteners (e.g., Velcro).
[0112] g. Individual finger components may be at least partially formed as sleeves that cover the back side of the finger but not the entire palm side of the finger.
[0113] i. Finger components can be hooked or slipped onto each individual finger.
[0114] ii. The finger component may allow the fingertip to be completely exposed, or have a small cover on the fingertip made of touch-friendly and / or non-slip material.
[0115] iii. The finger component may include a (semi-)rigid component or support ridge on the back side of the component for additional support. The bending of the (semi-)rigid component may be attributed to the stiffness of the material, the bending mechanism, and the opening and closing of the (semi-)rigid component.
[0116] h. Individual finger components can be removed independently from the finger and / or device. This can be achieved, for example, by clips, by opening rings, or by sliding from the fingertip.
[0117] i. The thumb component can be part of the finger sleeve or, like other finger sleeves, can be movable. The thumb can be secured / stabilized by a support ridge in the sleeve and / or additional rigid components (the material specified in e). Alternatively, it can be pulled to a neutral position via an elastic tensioner from the thumb component to the glove using suitable connectors such as hook / fastener / loop fasteners (e.g., Velcro).
[0118] j. The elastic tensioner can be attached to the proximal portion of the bridge and finger components and / or the support ridge (if provided). It can be attached to the bridge via a button, hook, buckle, strap, or other releasable connector.
[0119] k. The flexible component (such as an elastic tensioner) can be adjusted (preferably continuously) via a sliding buckle or other adjusting element. Such a component can be made of plastic, metal, or other suitable material.
[0120] 1. The back-of-hand bridge can be adjusted by an additional tensioner placed on the wrist or forearm, which allows for continuous adjustment. At least a portion of the tensioner can be connected to a support (if provided). For example, a fixed or removable connection to at least a portion of the support can be provided, such as via mating connectors and docking devices.
[0121] i. Bridging components may include hooks, snaps, and hook-and-loop fasteners (such as Velcro).
[0122] ii. If no additional tensioner is available, the bridging piece can be attached to the back of the hand sleeve.
[0123] iii. Additional tensioners may take the form of one (or more) tensioning wheels or other tensioning mechanisms.
[0124] iv. The adjustment button can be located at the proximal end of the hand sleeve to allow for maximum finger adjustment.
[0125] At least a portion of the thumb component may be formed as a fabric sleeve, and / or may include a fixed support structure, and / or have an adjustable support structure.
[0126] The thumb is preferably not adjusted by a bridging element and / or an adjusting handle (e.g., a center wheel), because positioning may only have a stretching effect without a functional effect. Therefore, the thumb is designed independently from the other fingers.
[0127] The wrist component can be made of plastic and fabric and includes an adjustment wheel, bridge, and zipper.
[0128] Hand sleeves made of soft material may include a hole and a thumb sleeve, the hole allowing all fingers to pass through together.
[0129] If minimal adjustment is required, the bridging member can be attached to the back of the glove, possibly removably in discontinuous locations, eliminating the need for an adjustment handle. Rotating the adjustment handle allows for very precise adjustment (which can be associated with controlled finger opening). The adjustment mechanism can provide a quick-release mechanism to release tension in the adjustment member 15 and / or unlock it.
[0130] o. Finger components can be primarily made of plastic and fabric, along with elastic bands. The palmar side (or: inner side) of the finger can be largely exposed (not covered by material). Supporting ridges can terminate before the nail or extend into cap-like structures covering the fingertip for additional support.
[0131] Unless otherwise expressly stated, elements and aspects discussed with respect to a particular embodiment or with respect to a particular embodiment may be appropriately combined with elements and aspects of other embodiments.
