Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthopedic rehabilitation technology, and in particular to an orthopedic arm rehabilitation device. Background Technology
[0002] Orthopedic rehabilitation is an important branch of rehabilitation and an indispensable part of the conservative treatment of various orthopedic diseases and injuries, as well as preoperative and postoperative management.
[0003] When a patient's arm is injured, the elbow joint may be unable to rotate for a prolonged period, leading to difficulty in arm movement and even muscle atrophy. Therefore, rehabilitation exercises for the arm are necessary.
[0004] A patent document with publication number CN222677126U discloses an orthopedic arm rehabilitation training device capable of providing active or passive rehabilitation exercises for the patient's arm. A bolt moves a push rod, causing an elastic block to move, which in turn rotates a second rotating plate. The width between the first slider and the side wall of the second frame gradually decreases from the rear end to the front end. Rotating the corresponding bolt controls the swing of the second rotating plate, adjusting the resistance encountered by the first slider during its sliding within the second frame. This facilitates active vertical movement of the patient's arm, accelerating rehabilitation and achieving better and more effective training results. The device allows for horizontal movement of the patient's arm, enabling multi-angle rotation and overcoming the limitation of existing training devices that only achieve single-plane rotation. Furthermore, the first and second massage balls on the first and second protective garments ensure compression of the patient's arm, enhancing the massage function and accelerating blood circulation, thus aiding in rehabilitation training.
[0005] Although the aforementioned orthopedic arm rehabilitation training device can solve the corresponding technical problems, it changes the resistance to the horizontal movement of the patient's arm by changing the amount of gas in the airbag. However, when the airbag is too full, it will block the arc-shaped groove, resulting in a reduction in the range of horizontal movement of the patient's arm, thereby reducing the arm rehabilitation effect.
[0006] Therefore, an orthopedic arm rehabilitation device is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-4This utility model provides an orthopedic arm rehabilitation device, including a support mechanism 100, a support mechanism 200, a rotation mechanism 300 for facilitating arm rotation training, and an adjustment mechanism 400 for adjusting rotation resistance. The support mechanism 100 is located above the support mechanism 200, the rotation mechanism 300 is located between the support mechanism 100 and the support mechanism 200, and the adjustment mechanism 400 is located on the rotation mechanism 300. The rotation mechanism 300 includes a rotating seat 310 located between the support mechanism 100 and the support mechanism 200 for adjusting the angle between the upper arm and the support mechanism 200, and a mechanism for enabling the patient's arm to rotate vertically. The driving component 340 for active exercise training, the supporting mechanism 100 is provided with a connecting component 320 that enables the patient's arm to perform active exercise training in the vertical direction, and a second rotating column 330 for enabling the patient's arm to perform active exercise training in the horizontal direction is provided between the rotating seat 310 and the supporting mechanism 200; the adjusting mechanism 400 is provided on the connecting component 320 and the second rotating column 330 respectively; the adjusting mechanism 400 includes symmetrically arranged squeezing blocks 410, the inner wall surface of the squeezing blocks 410 is fixedly connected to a damping plate 420, and the connecting component 320 and the supporting mechanism 200 are respectively provided with adjusting components for adjusting the distance between the corresponding two squeezing blocks 410.
[0032] It should be noted that the working principle of the aforementioned drive component 340 is consistent with the principle of the second frame internal structure disclosed in CN222677126U, which has the existing publication number CN222677126U. Starting the motor facilitates the patient to perform passive rehabilitation exercises. This is existing technology, so it will not be described in detail in this technical solution.
[0033] The support mechanism 100 includes a first brace 110 for supporting the patient's upper arm and movably connected to one side of the top of the support mechanism 200 via a rotating seat 310. A second brace 120 for supporting the patient's forearm is rotatably connected to one side of the first brace 110 via a connector 320. Multiple equidistant straps 130 are fixedly connected to both the first brace 110 and the second brace 120. The side of the second brace 120 away from the first brace 110 is connected to the fixed seat of the drive component 340. The straps 130 can firmly fix the patient's upper arm and forearm in the first brace 110 and the second brace 120 respectively, which facilitates subsequent rehabilitation training using the rotating mechanism 300.
[0034] The support mechanism 200 includes a base plate 210 located below the first guard 110 and the second guard 120. The top of the base plate 210 is rotatably connected to the first guard 110 via a rotating seat 310. A drive member 340 is movably located on the top of the base plate 210. A second rotating column 330 is fixedly connected to the bottom of the rotating seat 310, and the bottom end of the second rotating column 330 extends movably through to the bottom of the base plate 210. Two pressing blocks 410 are located on both sides of the surface of the second rotating column 330, and one adjusting member is located at the bottom of the base plate 210. The support mechanism 200 provides an installation base for the support mechanism 100, the rotating mechanism 300, and the adjusting mechanism 400.
[0035] The support mechanism 200 also includes support legs 220. Each of the four corners of the bottom of the base plate 210 is fixedly connected to a support leg 220. The height of the support leg 220 is greater than the height of the second rotating column 330. The support legs 220 can support and raise the base plate 210, so that the base plate 210 can be stably placed in the required position and the second rotating column 330 can rotate normally.
[0036] The connector 320 includes a first support 321 fixedly connected to the first protective gear 110, and a second support 322 fixedly connected to the second protective gear 120 for use with the first support 321. A first rotating column 323 passes through both the first support 321 and the second support 322. The surface of the first rotating column 323 is fixedly connected to the through-hole of the first support 321, and the surface of the first rotating column 323 is rotatably connected to the through-hole of the second support 322. Two other compression blocks 410 are located on both sides of the surface of the first rotating column 323, and another adjusting member is located on one side of the first support 321. The connector 320 enables the rotatable connection between the first protective gear 110 and the second protective gear 120, so that the patient's upper arm and forearm can perform rehabilitation movements in the vertical direction.
[0037] The adjusting component includes a threaded sleeve 430 fixedly connected to one side of the extrusion block 410. A bidirectional bolt 440 is threaded through two adjacent threaded sleeves 430. One end of the bidirectional bolt 440 is rotatably connected to a convex plate 450 via a bearing. The two convex plates 450 are respectively fixedly connected to one side of the first support 321 and the bottom of the base plate 210. One side of the first support 321 and the bottom of the base plate 210 respectively contact one side of the corresponding threaded sleeve 430. By rotating the bidirectional bolt 440, under the action of the thread, the bidirectional bolt 440 can drive the two threaded sleeves 430 on its surface to move towards each other, which can drive the damping plate 420 to move, so that the first rotating column 323 or the second rotating column 330 respectively contact the corresponding damping plate 420 to increase the resistance, thereby achieving the effect of adjusting the rotation damping of the first rotating column 323 and the second rotating column 330.
[0038] The base plate 210 has a side groove 211 on its surface. The side groove 211 is aligned with the position of the bidirectional bolt 440 at the bottom of the base plate 210. The bidirectional bolt 440 at the bottom of the base plate 210 can be easily rotated through the side groove 211.
[0039] The base plate 210 has a groove 230 on its top, and a slider 240 is slidably connected to the inner cavity of the groove 230. The top of the slider 240 is fixedly connected to the bottom of the drive member 340. When the patient's arm is actively moving in the horizontal direction, the support mechanism 100 can drive the drive member 340 and the slider 240 to move synchronously, so that the slider 240 can move in the groove 230, thereby guiding the drive member 340 and improving the stability of the support mechanism 100 when it rotates horizontally around the second rotating column 330.
[0040] The cross-sections of the groove 230 and the slider 240 are inverted T-shaped, which can effectively prevent the slider 240 from slipping out of the inner cavity of the groove 230.
[0041] The drive component 340 and the second protective gear 120 are connected to a fixed base via a bearing via an adjusting bolt 342. A U-shaped block 341 is threaded onto the surface of the adjusting bolt 342 and slidably connected to the surface of the fixed base. A slot 121 is provided on the side of the second protective gear 120 away from the first protective gear 110. One side of the U-shaped block 341 is inserted into the inner cavity of the slot 121. By rotating the adjusting bolt 342, the U-shaped block 341 can slide on the fixed base of the drive component 340 under the action of the thread, so that the U-shaped block 341 can be disengaged from or inserted into the slot 121. This allows for the disassembly or connection of the drive component 340 and the second protective gear 120. This enables the disassembly of the drive component 340 and the second protective gear 120 during active exercise training in the vertical direction, reducing the need for additional structures during arm exercise training. Connecting the drive component 340 and the second protective gear 120 facilitates passive exercise training of the patient's arm in the vertical direction or active exercise training in the horizontal direction.
[0042] The slide groove 230 and the damping plate 420 are both arc-shaped structures, and the slide groove 230 and the second rotating column 330 are coaxially arranged.
[0043] The working principle of this utility model is as follows: the patient's upper arm and forearm are fixed in the first protective gear 110 and the second protective gear 120 respectively by the strap 130; when the patient's arm is passively exercised in the vertical direction, the driving component 340 can drive the second protective gear 120 and the second support 322 to swing vertically around the first rotating column 323, which facilitates the patient's passive rehabilitation exercise; when the patient's arm is actively exercised in the horizontal direction, the patient's arm can drive the support mechanism 100, the rotating mechanism 300 and the slider 240 to swing horizontally synchronously around the second rotating column 330, and the slider 240 slides in the inner cavity of the groove 230; when the patient's arm is actively exercised in the vertical direction, the adjusting bolt 342 is rotated, and the adjusting bolt 342 drives the U-shaped block 341 to slide on the fixed seat surface of the driving component 340 until... U-shaped block 341 disengages from the inner cavity of slot 121, thereby separating the second protective gear 120 from the driving component 340. At this time, the patient's forearm can drive the second protective gear 120 and the second support 322 to swing vertically around the first rotating column 323, which facilitates the patient's active rehabilitation exercise. By rotating the bidirectional bolt 440 at the bottom of the base plate 210, the two threaded sleeves 430 on its surface move towards each other under the action of the thread. The threaded sleeves 430 drive the compression block 410 and the damping plate 420 to move synchronously, so that the first rotating column 323 and the second rotating column 330 contact and compress with the corresponding damping plate 420. By controlling the force applied to the first rotating column 323 and the second rotating column 330, the rotational resistance of the first rotating column 323 and the second rotating column 330 can be controlled, thereby meeting the arm rehabilitation exercise needs of different patients.
[0044] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
