Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an upper limb rehabilitation training device. Background Technology

[0002] In daily life, the forearms, wrists, and finger joints of the human upper limbs frequently undergo extensive bending activities. Due to prolonged physical labor, the joints are subjected to excessive loads for extended periods, which can lead to joint damage. Furthermore, with age, degenerative changes can occur in the joints. Severe wear and tear on the wrist joint, coupled with insufficient calcium intake, can cause decreased bone density in the joints, resulting in joint damage during friction. Additionally, external impacts to the joints can also cause soft tissue damage. Wrist or finger joint injuries can cause significant inconvenience to daily life.

[0003] The initial treatment for joint injuries usually involves applying or taking medication externally or internally, or resting and recovering. Later, auxiliary rehabilitation training for the joint is required. There are some medical devices on the market that are designed for rehabilitation training of the wrist or finger joints of the upper limbs, but these devices are often not comprehensive enough or have a complex structure that makes them inconvenient to use. Summary of the Invention

[0004] To address the aforementioned problems, this utility model aims to provide an upper limb recovery training device. By designing a forearm rotation component, the device assists in the recovery and obstacle training of the forearm as a whole by rotating the forearm. By designing a wrist training component, the device assists in the recovery and obstacle training of the wrist joint. It has the advantages of comprehensive functions, simple structure, good flexibility, and ease of use.

[0005] The main idea of ​​the technical solution adopted by this utility model is as follows: a forearm rotation component is designed, which uses a synchronously rotating dual-axis motor to cooperate with the rack at the bottom of the forearm carrier sleeve to drive the forearm carrier sleeve to rotate, thereby assisting in the recovery training of the forearm. A wrist training component is designed, which uses a rotating motor located on the rotating ring to drive the handle to rotate, thereby driving the wrist to perform bending training.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An upper limb rehabilitation training device includes a base plate, on which a fixed seat and a support frame are slidably disposed. The fixed seat is provided with a forearm rotation component for assisting forearm rehabilitation, and the support frame is provided with a wrist training component for assisting wrist joint rehabilitation.

[0008] The forearm rotation assembly includes a forearm carrier sleeve rotatably mounted above a fixed base. The fixed base contains a dual-axis motor, and the power output shafts at both ends of the dual-axis motor are rotatably connected to racks on both sides of the bottom of the forearm carrier sleeve.

[0009] The wrist training component includes a rotating ring rotatably mounted on a support frame, a grip connecting frame rotatably mounted on one side of the rotating ring, a grip rotatably mounted on the grip connecting frame, and a rotating motor mounted on the rotating ring. The power output shaft of the rotating motor is rotatably connected to the bottom end of the drive grip connecting frame.

[0010] The handle is also elastically connected with multiple loops to assist finger recovery.

[0011] The base plate is provided with guide slides, and the bottom of the fixed seat and the support frame are provided with guide slide grooves that fit tightly with the guide slides.

[0012] The forearm carrier sheath is also equipped with elastic straps to enhance the forearm fixation effect.

[0013] The beneficial effects of this utility model are:

[0014] 1. By designing a forearm rotation component and a wrist training component, the dual-axis motor rotates synchronously at both ends, driving the rack to rotate the forearm carrier sleeve, and driving the forearm and wrist to rotate as a whole. The rotating motor also drives the handle held by the hand to rotate, thereby assisting the wrist in bending training. This makes the present invention convenient to use.

[0015] 2. By designing a forearm rotation component and a wrist training component, the forearm can undergo rotational recovery training and wrist flexion training. An elastic connecting collar is set on the handle to assist the fingers in muscle and joint recovery training, making the functions of this utility model more comprehensive.

[0016] 3. By sliding the fixed base and support frame onto the base plate, this device can be adjusted according to the upper limb length of different users, and by setting elastic straps, the forearm carrier sleeve can be adjusted according to the user's forearm size, thereby improving the flexibility of this utility model.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] The inventors discovered that the human upper limbs, especially the wrist joints, are prone to injury due to long-term physical labor, excessive load on the joints, aging, insufficient nutrient intake, or external impact. Existing devices for post-operative rehabilitation training of the upper limbs and wrist joints often have shortcomings such as insufficient functionality, complex structure, and inconvenience in use.

[0031] Based on the above findings, this application proposes an upper limb rehabilitation training device. By designing a forearm rotation component, a synchronously rotating dual-axis motor engages with a rack at the bottom of the forearm carrier sleeve to drive the forearm carrier sleeve to rotate, thereby assisting in forearm rehabilitation training. A wrist training component is also designed, in which a rotating motor located on a rotating ring drives the handle to rotate, thereby driving the wrist to perform flexion training. It has the advantages of comprehensive functions, simple structure, good flexibility, and ease of use.

[0032] See Figures 1-4 This application discloses an upper limb rehabilitation training device, including a base plate 1. A fixed seat 2 and a support frame 3 are slidably disposed on the base plate 1. Specifically, the base plate 1 can be made of a metal or plastic material with good strength. A guide slide 101 is disposed in the middle of the base plate 1. A guide groove 8 is provided at the middle of the bottom surface of the fixed seat 2 and the support frame 3, which is in close contact with the guide slide 101. By setting the guide slide 101 and the guide groove 8 in close contact, the device can be flexibly adjusted according to the different overall lengths of the user's upper limb arm. At the same time, it is not easy to slip when performing auxiliary training on the forearm or wrist joint, which improves the flexibility of the present invention and thus expands its applicability. It should be noted that the cross-sectional shape of the guide groove 8 and the guide slide 101 should avoid being a regular shape with the upper dimension smaller than the lower dimension, so as to prevent the fixed seat 2 or the support frame 3 from falling off the base plate 1.

[0033] See Figure 9 The fixed base 2 is rectangular in shape and is made of high-strength metal or plastic. A semi-cylindrical cavity is provided at the top of the fixed base 2. Multiple rack grooves 201 for mounting rack 404 are provided in the semi-cylindrical cavity. Rack limiting grooves 202 are also provided on both sides of the rack grooves 201 to guide the rotation direction of rack 404 and prevent damage to the arm due to excessive rotation of rack 404.

[0034] The fixed base 2 is equipped with a forearm rotation assembly 4 for assisting forearm recovery, see reference. Figure 5 as well as Figure 6 The forearm rotation assembly 4 includes a forearm carrier sleeve 401 rotatably mounted above the fixed base 2. (See reference...) Figure 8 The forearm carrier sleeve 401 is a horizontally placed annular cylindrical structure with a break at its upper end. The forearm carrier sleeve 401 is made of a plastic material with a certain degree of elasticity. Multiple elastic straps 9 are provided at the break at the upper part of the forearm carrier sleeve 401, which allows the forearm carrier sleeve 401 to be adjusted according to the different arm thicknesses of different users and to improve the fixation effect of the forearm carrier sleeve 401 on the forearm.

[0035] A number of racks 404 are fixed at the bottom of the forearm carrier sleeve 401, which cooperate with the rack grooves 201 on the fixed base 2. On both sides of the rack 404 near the top, rack limit blocks 405 are provided to cooperate with the rack limit grooves 202. Through the action of the rack limit blocks 405 and the rack limit grooves 202, the rack 404 is prevented from rotating too much and causing damage to the arm. At the same time, in some embodiments, the overall length of the rack 404 or the number of teeth can be reduced to allow the forearm carrier sleeve 401 to rotate at a smaller angle.

[0036] The lower end of the fixed base 2 has a cavity, and a dual-axis motor 402 is located in the middle of the cavity. Dual-axis motor gears 403 are fixed on the power output shafts at both ends of the dual-axis motor 402. The dual-axis motor gears 403 and rack 404 cooperate with each other and are meshed and rotated. In some embodiments, a switch for controlling the forward or reverse rotation of the dual-axis motor 402 can be added to the outer surface of the fixed base 2. It should be noted that the power output shafts at both ends of the dual-axis motor 402 described in this utility model can rotate synchronously, or in some embodiments, multiple motors of the same specification can be set to drive the rack 404. When the dual-axis motor 402 is started, it can drive the dual-axis motor gears 403 at both ends to rotate, and drive the rack 404 to rotate, thereby causing the forearm carrier sleeve 401 to drive the user's forearm to rotate as a whole.

[0037] The support frame 3 is equipped with a wrist training component 5 for assisting wrist joint recovery. The wrist training component 5 includes a rotating ring 501 rotatably mounted on the support frame 3. Specifically, see [reference needed]. Figure 10 The support frame 3 has an overall shape that is wider at the bottom, narrower in the middle, and has a semi-circular ring structure at the top. A rotating ring groove 301 that matches the semi-circular ring structure is provided at the top. It should be noted that in some embodiments, the support frame 3 is made of plastic material that has good strength and a certain degree of elasticity. In addition, the cross-sectional shape of the semi-circular ring structure at the top of the support frame 3 should be no less than 1 / 2 of a circle to prevent the rotating ring 501 from falling off.

[0038] The rotating ring 501 is a hollow cylindrical structure with a circular cross-section. One end of the rotating ring 501 is provided with a circular plane for installing other structures, and the middle part of the rotating ring 501 is provided with a circular protrusion that cooperates with the rotating ring groove 301.

[0039] See Figure 7On one side of the rotating ring 501, specifically on one side of the annular plane of the rotating ring 501, and on both sides of the hollow part in the middle, there are connecting bracket mounting seats 503. The bottom end of the handle connecting bracket 502 is rotatably mounted on the connecting bracket mounting seat 503 by means of a rotating shaft connection. The top end of the handle connecting bracket 502 is rotatably mounted on the handle 504 by means of a rotating shaft connection.

[0040] A rotating motor 505 is located on the rotating ring 501 and on one side of the connecting frame mounting base 503. A rotating motor gear 506 is fixed on the power output shaft of the rotating motor 505, and a tooth groove is opened on the rotating shaft at the bottom of the grip connecting frame 502 to match the rotating motor gear 506. In some embodiments, a switch that can drive the rotating motor 505 to rotate in the forward or reverse direction can be set on the rotating ring 501. When the rotating motor 505 is started, it can drive the grip connecting frame 502 to rotate in the forward or reverse direction through the rotating motor gear 506, thereby driving the grip 504 to rotate. When the user holds the grip 504, it can assist the user's wrist joint in bending training. In addition, while bending the wrist joint, forearm rotation training can also be performed simultaneously, thereby improving the overall recovery effect of the upper limb.

[0041] In addition, for users whose forearms and wrists have already recovered to a certain extent, they can independently perform forearm rotation and wrist flexion movements without starting the dual-axis motor 402 or the rotary motor 505. By overcoming the resistance of the motor torque, they can further strengthen the upper limbs as a whole.

[0042] The handle 504 is also elastically connected to a plurality of loops 6 for assisting finger recovery. Each loop 6 is connected to the surface of the handle 504 by an elastic cord 7 with good elasticity. The loops 6 and the elastic cord 7 can be made of materials such as rubber with good elasticity. Users can insert their five fingers into the loops 6 and stretch their five fingers to resist the elastic force generated by the elastic cord 7, so as to comprehensively exercise the muscles and joints of the fingers.

[0043] By combining the forearm rotation component 4 with the wrist training component 5, the user's arm and wrist joints can undergo assisted recovery training. The ring 6 is used to train the overall muscles and joints of the fingers, which helps to improve the overall recovery effect of the upper limbs and makes the function of this utility model more comprehensive.

[0044] The user inserts his upper limb into the forearm carrier sleeve 401 until his fingers pass through the collar 6 and he holds the handle 504. He adjusts the position between the fixing seat 2 and the support frame 3 and tightens the elastic strap 9 so that the forearm fits tightly against the forearm carrier sleeve 401.

[0045] Start the dual-axis motor 402, and through the rotation of the dual-axis motor gear 403 and rack 404, drive the forearm carrier sleeve 401 to rotate, thereby driving the user's forearm to rotate at a small angle; start the rotation motor 505, and through the rotation of the rotation motor gear 506 and handle connecting frame 502, drive the handle 504 to rotate, thereby driving the user's wrist joint to rotate.

[0046] When the dual-axis motor gear 403 or the rotating motor 505 is not started, the forearm or wrist joint can be exercised by autonomously rotating the forearm or wrist joint and overcoming the resistance of the motor torque.

[0047] When the user holds the handle 504, they can extend their fingers and strengthen the muscles and joints of the fingers by resisting the elasticity of the elastic rope 7.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
