Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and specifically relates to a wrist stabilizer for rehabilitation. Background Art

[0002] In the field of rehabilitation medicine, wrist injuries are common conditions, and usually, wearing a stabilizer is required to assist in rehabilitation treatment. Most of the existing wrist stabilizers support and protect the wrist by means of a fixed bracket and an elastic band to limit excessive movement and posture deviation of the wrist. However, these traditional designs have the following problems:

[0003] Complex structure and large weight:

[0004] Most traditional wrist stabilizers use metal brackets or heavy materials to ensure their supporting force, which not only increases the overall weight of the device but also makes the wearing and adjustment processes cumbersome, causing inconvenience to users during daily use.

[0005] The overly complex structure makes users spend more time and effort when wearing and adjusting the posture. Especially for users lacking flexibility or suffering from wrist pain, the operation process becomes difficult.

[0006] Inflexible adjustment and inability to meet personalized needs:

[0007] Some existing stabilizers are adjusted by fixed angles or elastic bands, but they often only provide a limited adjustment range and cannot flexibly meet the needs of different users for wrist postures during the rehabilitation process.

[0008] In addition, these devices usually require repeated disassembly or refixing during adjustment, lacking a quick and simple adjustment mechanism, which is extremely inconvenient during daily use or rehabilitation training.

[0009] Uncomfortable to wear and affecting daily life:

[0010] Many stabilizers lack consideration for the wearing comfort of users in their designs. The rigid structure or tight wrapping will cause a sense of compression on the wrist and arm, making users feel uncomfortable when wearing for a long time.

[0011] Due to the lack of an adaptable structure in existing products, users may be restricted in their activities when wearing these devices and it is difficult to perform basic operations in daily life, such as typing and picking up items, which limits their actual use scenarios. Summary of the Invention

[0012] The objective of the present invention is as follows: The present invention aims to provide a wrist stabilizer for rehabilitation. Through a lightweight and flexible design, the present invention not only ensures the comfort of wearing and the stability of the wrist posture, but also provides a convenient adjustment mechanism, enabling users to easily adjust the posture and the supporting force according to their rehabilitation needs and daily life requirements. This design aims to make up for the deficiencies of the prior art and provide users with a more efficient and comfortable rehabilitation experience.

[0013] The technical solution adopted by the present invention is as follows:

[0015] Among them, the arc convex part is located in the middle of one end of the chain block monomer, and the diameter of the arc convex part is smaller than the width and height of the chain block monomer; the arc concave part is located in the middle of the other end of the chain block monomer, and the diameter of the arc concave part is larger than the diameter of the arc convex part.

[0016] Among them, an air cushion layer is arranged on the inner surface of the wearing sleeve; the air cushion layer is communicated with a pressing air bag through an air inlet pipe, and the air cushion layer is inflated by pressing the pressing air bag; a first one-way air valve for unidirectional air intake towards the air cushion layer is arranged on the air inlet pipe; a second one-way air valve for unidirectional air intake towards the pressing air bag is arranged on the pressing air bag; an openable and closable exhaust port is arranged on the air cushion layer.

[0017] Among them, the wearing sleeve is integrally formed of an elastic material.

[0018] Wherein, the wearable sleeve includes a palm part, a wrist part and an arm part; the palm part and the arm part are made of rigid plastic; the wrist part includes a plurality of rigid ring monomers; both ends of the rigid ring monomer are spirally bent into interlocking parts; adjacent two rigid ring monomers are interlocked through the interlocking parts and can rotate relative to each other.

[0019] Wherein, at least one guiding block is arranged on the wrist part.

[0020] Wherein, the front end of the arc convex part is an elastic layer; the pyramid protrusions of the arc convex part are fixed on the elastic layer.

[0021] Wherein, permanent magnets are respectively embedded in the arc convex part and the arc concave part, and the opposite surfaces of the arc convex part and the arc concave part repel each other with the same polarity.

[0022] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0025] The design structure of the posture fixing chain is simple and concise. Through the smooth guidance of the guiding block, it is ensured that the chain will not get stuck during adjustment. The entire adjustment process is simple and easy to perform, and users can quickly complete the posture adjustment.

[0026] 2. Flexible adjustment function:

[0027] By rotating the adjusting block to tighten or loosen the wire rope, users can conveniently adjust the tightness between the chain block monomers, realizing flexible adjustment of the wrist posture. This adjustment design is both simple and efficient, and users can adjust the wrist posture at any time under different circumstances.

[0028] The pyramid protrusions between the arc convex part and the concave part provide a stable clamping effect when the wire rope is tightened; when the wire rope is loosened, the repulsive force of the permanent magnet ensures the free separation of the chain block monomers, enabling users to perform flexible and convenient adjustment without complex operations.

[0029] 3. Stable effect on wrist posture:

[0030] Through the precise design and clamping structure of the chain block monomers, the present invention can firmly fix the user's wrist in the set position, ensuring stable posture. This stable effect is crucial for the rehabilitation process, and it can help users maintain the correct posture and prevent the wrist from bending excessively.

[0031] The fitting support provided by the air cushion layer further enhances stability, enabling users to obtain sufficient support and enjoy comfort during use.

[0032] In summary, through its simple and lightweight structural design, the present invention successfully realizes the flexible adjustment and stable fixation of the wrist posture, ensuring that users can obtain the best support and protection effects during rehabilitation and daily use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Embodiment 1: Refer to Figures 1 to 4The present invention relates to a wrist stabilizer for rehabilitation, including a wearing sleeve 1, which is put from the front of the palm to the back of the wrist; finger holes are opened at the front end of the wearing sleeve 1 corresponding to the five fingers; the front end of the wearing sleeve 1 is put to the base of the fingers so that most of the fingers are exposed; the specific wearing sleeve 1 is integrally formed of a high-elastic TPU (thermoplastic polyurethane) material, which has high strength, wear resistance and good elasticity to ensure that the user can obtain sufficient support when using it without causing pressure on the skin.

[0042] A plurality of guide blocks 3 are respectively arranged on the side of the wearable sleeve 1 corresponding to the back of the hand, along the back of the palm, and from the wrist to the back of the wrist; the guide blocks 3 are made of light metal (such as aluminum alloy) and have high strength and corrosion resistance. Each guide block is fixed to the wearable sleeve 1 by screws and arranged according to the shape of the wrist and palm to ensure that the posture fixing chain 4 will not get stuck when sliding at different angles.

[0043] A posture fixing chain 4 passes through each guide block 3 in sequence; an elastic jacket 41 is provided on the outer cover of the posture fixing chain 4; the posture fixing chain 4 includes a plurality of chain block monomers 42 which are opposite to each other in sequence and a pull wire 43 which slides axially through the center of each chain block monomer 42 at the same time; these chain block monomers are injection molded by engineering plastics, which are light and wear-resistant. The size of each chain block monomer is precisely calculated to ensure that the chain block monomer 42 can form a stable posture fixing effect when in contact. The jacket is made of silicone material, which has good softness, ensuring that the chain will not directly contact the skin during use and cause discomfort, while limiting the relative position of each chain block monomer 42 in the posture fixing chain 4 to avoid excessive misalignment and inability to engage in a fixed posture.

[0044] One end of the pull wire 43 is fixed on a chain block monomer 42 located at the outermost end, and the other end passes through each chain block monomer 42 in turn and is fixed to an adjustment block 44. The pull wire is made of high-strength steel wire rope and can withstand high tension. The adjustment block 44 is threadedly matched with the guide block 3 located at the other outermost end. The adjustment block 44 is rotated to adjust the tightness of the contact of each chain block monomer 42 through the pull wire 43 to fix or loosen the relative posture between each chain block monomer 42; a curved convex portion 421 is set at one end of the chain block monomer 42, and a curved concave portion 422 is set at the other end. The curved convex portion 421 and the curved concave portion 422 are in contact and matched between adjacent chain block monomers 42; the curved convex portion 421 and the curved concave portion 422 are evenly provided with polygonal pyramidal protrusions 423 respectively; when the curved convex portion 421 and the curved concave portion 422 are in contact and pre-tightened, the polygonal pyramidal protrusions 423 of the two are engaged with each other to fix the relative posture of the two.

[0045] The arc-shaped convex part 421 is located in the middle of one end of the chain block unit 42, and the diameter of the arc-shaped convex part 421 is smaller than the width and height of the chain block unit 42; the arc-shaped concave part 422 is located in the middle of the other end of the chain block unit 42, and the diameter of the arc-shaped concave part 422 is larger than the diameter of the arc-shaped convex part 421. In this way, it not only ensures a good clamping and fixing posture effect when two adjacent chain block units 42 rotate relative to each other, but also avoids interference and blockage at the periphery of the ends of adjacent chain block units 42. The front end of the arc-shaped convex part 421 is an elastic layer 424; the pyramid protrusions 423 of the arc-shaped convex part 421 are fixed on the elastic layer 424. The elastic layer 424 is made of flexible rubber material. By using its ability to adaptively deform under extrusion, the pyramid protrusions 423 of the arc-shaped convex part 421 and the arc-shaped concave part 422 can adaptively engage more, thereby improving the posture fixing effect and stability.

[0046] Neodymium iron boron permanent magnets are respectively embedded in the arc-shaped convex part 421 and the arc-shaped concave part 422, and the opposite surfaces of the arc-shaped convex part 421 and the arc-shaped concave part 422 repel each other with the same polarity. The magnetism of the permanent magnet does not need to be very strong, as long as it ensures that in the static state, the adjacent arc-shaped convex part 421 and arc-shaped concave part 422 are separated from each other and do not contact; in this way, when the pull wire 43 is loosened, the adjacent arc-shaped convex part 421 and arc-shaped concave part 422 are separated from each other and do not engage, so that the angle of passing through the wrist can be freely adjusted. After the wrist angle is adjusted in place, then tighten the pull wire 43 to make the adjacent arc-shaped convex part 421 and arc-shaped concave part 422 overcome the repulsive force of the permanent magnet and engage, thereby fixing the wrist bending angle and posture.

[0047] An air cushion layer 2 is provided on the inner surface of the wearing sleeve 1; the air cushion layer is made of flexible silica gel material and can be precisely fitted according to the curve of the wrist. The first one-way air valve 23 provided on the air inlet pipe 21 is a low-pressure check valve, which can ensure that gas enters the air cushion layer 2 unidirectionally and avoid backflow. Pressing the second one-way air valve 24 of the air bag 22 ensures that gas can smoothly enter the air inlet pipe 21 when pressed. A manual exhaust port is also provided on the air cushion layer 2, and the exhaust port adopts a rotary opening and closing design for easy adjustment of air pressure.

[0048] The method for a user to use the wrist stabilizer for rehabilitation of the present invention is as follows:

[0049] 1. Wear the wearing sleeve 1:

[0050] The user wears the wearing sleeve 1 starting from the front of the palm and then puts it on the back of the wrist, ensuring that the palm and wrist parts are covered.

[0051] Pass the five fingers through the finger holes at the front end of the wearing sleeve 1 in sequence, and adjust until the finger holes of the wearing sleeve are fixed at the roots of the fingers, so that most of the fingers are exposed to maintain the freedom of movement of the fingers.

[0052] 2. Adjust the pressure of the air cushion layer 2:

[0053] According to the comfort level of the wrist, the user presses the airbag 22 to inflate the air cushion layer 2. When pressing, the gas enters the air cushion layer 2 through the air inlet pipe 21. The first one-way air valve 23 on the air inlet pipe 21 ensures that the gas can only enter unidirectionally, preventing backflow.

[0054] When the air pressure in the air cushion layer 2 reaches a comfortable and stable state, the user stops pressing. Through the buffering effect of the air cushion layer 2, the user can feel appropriate support and comfort on the palm, wrist, and arm.

[0055] If it is necessary to release gas or adjust the air pressure, the exhaust port on the air cushion layer 2 can be manually opened, and the air pressure in the air cushion layer can be adjusted through a rotary opening and closing design to reach a suitable support state.

[0056] 3. Adjust the tightness of the posture fixing chain 4:

[0057] The user first bends the wrist to the posture to be maintained, and then rotates the adjustment block 44 to adjust the tension of the pull wire 43, thereby adjusting the relative posture between the chain block monomers 42. When rotating the adjustment block 44, the pull wire 43 tightens or relaxes the chain block monomer 42 through the guiding block 3.

[0058] When the pull wire 43 is tightened, the arc convex parts 421 and concave parts 422 between the chain block monomers 42 approach each other and are engaged through the multi-pyramid protrusions 423, thereby fixing the angle and posture of the wrist.

[0059] If it is necessary to adjust the wrist angle, the user can rotate the adjustment block 44 counterclockwise to relax the pull wire 43, and by means of the repulsive force of the permanent magnets in the arc convex part 421 and the concave part 422, separate the adjacent chain block monomers 42, thereby allowing free adjustment of the wrist angle.

[0060] After the user adjusts the wrist to a suitable angle according to the rehabilitation needs, rotate the adjustment block 44 clockwise again to tighten the pull wire 43, so that the arc convex part 421 and the concave part 422 between the chain block monomers 42 overcome the repulsive force of the permanent magnets and are tightly engaged, fixing the bent angle and posture of the wrist.

[0061] In the present invention, the support and buffering principle of the wearing sleeve 1:

[0062] The wearing sleeve 1 is made of high-elastic TPU material, with high strength, wear resistance, and good elasticity, and can provide sufficient support without causing a sense of compression on the skin. After the air cushion layer 2 is filled with gas, it will fit precisely according to the curve of the wrist to form a stable buffer zone. This buffer zone not only disperses the external pressure but also provides a certain amount of support force, enhancing the comfort and support of the wearing sleeve.

[0063] The structure and engagement principle of the guiding block 3 and the posture fixing chain 4:

[0064] The guiding block 3 is made of lightweight aluminum alloy and is arranged along the back of the palm and the wrist, used to guide and fix the posture fixing chain 4 to ensure smooth sliding of the chain during use without jamming.

[0065] The posture fixing chain 4 is composed of multiple chain block monomers 42, and these chain blocks are connected to each other through the arc convex part 421 and the concave part 422. The multi-pyramid protrusions 423 between the chain blocks engage and fix the posture when the pulling wire 43 is tightened. When the pulling wire 43 is loosened, the chain block monomers are separated due to the same-sex repulsive force of the permanent magnets, enabling the chain blocks to move freely.

[0066] The magnetic-assisted separation and fixation principle of the posture fixing chain:

[0067] Neodymium iron boron permanent magnets are embedded in the arc convex part 421 and the concave part 422. When the pulling wire 43 is loosened, the same-sex repulsive force generated by the permanent magnets automatically separates the adjacent chain block monomers 42 to prevent unnecessary engagement. This design ensures that users can freely rotate the chain block monomers when adjusting the wrist angle without manual disassembly.

[0068] When the user adjusts the wrist angle and tightens the pulling wire 43, the tension of the pulling wire overcomes the repulsive force of the permanent magnets, causing the multi-pyramid protrusions 423 of the arc convex part 421 and the concave part 422 to engage tightly, thus stably fixing the wrist posture.

[0069] The protection and restriction function of the elastic outer sleeve 41:

[0070] The outside of the posture fixing chain 4 is wrapped with an elastic outer sleeve 41 made of silica gel. It not only protects the chain from direct contact with the skin, avoiding abrasion and discomfort, but also restricts the relative positions of the chain block monomers 42 through the soft material, preventing them from being misaligned or disengaged during the adjustment process.

[0071] The pressure control principle of the adjustable air cushion 2:

[0072] The pressure inside the air cushion 2 is controlled by pressing the airbag 22. When pressing, gas is transported to the air cushion 2 through the air inlet pipe 21. The first one-way air valve 23 ensures that the gas can only enter the air cushion unidirectionally, preventing gas from flowing back. The air pressure inside the air cushion 2 is adjusted through the rotary exhaust port to ensure that users can freely control the strength of wrist support at different rehabilitation stages. Embodiment

[0073] Please refer to Figure 5 and 6, The difference between this embodiment and the first embodiment is that the wearing sleeve 1 includes a palm part 11, a wrist part 12, and an arm part 13; the palm part 11 and the arm part 13 are made of rigid plastic to ensure sufficient support and stability while remaining lightweight. The rigid structure of these parts helps to stabilize the wrist and arm, preventing excessive bending or incorrect postures, while providing free space for finger movement. The palm part 11 is provided with finger holes and has enough space for the fingers to be exposed, facilitating the user's activities.

[0074] The wrist part 12 includes a plurality of rigid ring monomers 121; these monomers are made of aluminum alloy material and are formed into spiral interlocking parts 122 after bending. Adjacent ring monomers are connected to each other through the interlocking parts 122 and can rotate relatively freely to a certain extent to adapt to different postures of the wrist. This design enables the wrist part 12 to be finely adjusted according to the user's wrist posture, ensuring that the wrist can move within a certain range during wearing. However, when exceeding this range, the supporting force provided by the rigid ring monomers 121 limits the excessive rotation or bending of the wrist, thereby protecting the wrist from injury.

[0075] Among them, at least one guiding block 3 is provided on the wrist part 12. At least one guiding block 3 is provided on the wrist part 12 for guiding the posture fixing chain 4. The function of this guiding block is to ensure that the chain can slide stably along the wrist area, so that when adjusting the chain block monomer 42, the chain can run smoothly without jamming.

[0076] Through this guiding design, the posture fixing chain 4 can precisely adjust the bending and supporting angles of the wrist, enabling the user to adjust the tightness of the chain to achieve wrist posture fixing and support adjustment.

[0077] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
