Description

Technical Field

[0001] The utility model relates to an upper limb rehabilitation training device, in particular to an upper limb multi-joint rehabilitation training device. Background Art

[0002] During the medical care process, we often encounter patients who have lost a lot of upper limb function due to injuries. During the patient's recovery process, they need to recover the upper limb muscles and nerves through exercise and neuromuscular electrical stimulation therapy.

[0003] Specific upper limb training mainly includes functional training of the shoulders, elbows, and wrists. Shoulder joint training includes abduction, adduction, and extension; elbow joint training includes flexion, extension, and internal and external rotation; wrist joint flexion in the palm direction and dorsiflexion in the palm-dorsal direction, as well as sagittal axis radial and ulnar lateral bending and rotation training.

[0004] However, existing upper limb rehabilitation devices mostly target a specific joint. For example, CN111110516B discloses a three-degree-of-freedom wrist joint rehabilitation training mechanism for upper limb rehabilitation. During use, it can only perform multi-degree-of-freedom training on the wrist joint, making it difficult to exercise the palm or other parts of the hand. For another example, utility model patent CN202222675847 discloses an upper limb rehabilitation auxiliary device for hemiplegic patients. When used, it fixes the forearm, palm, and fingers, and uses a pulley setting to exercise the muscles around the shoulder joint, but cannot exercise the elbow and wrist joints. In addition, the angle of the device is fixed, making it impossible to perform multi-degree-of-freedom training on the shoulder joint.

[0005] For neuromuscular electrical stimulation therapy, electrical stimulation must be able to act accurately and effectively on the target muscle groups. However, for patients with more upper limb function loss, they are unable to achieve and maintain a specific posture, which may easily lead to the electrical stimulation therapy being unable to effectively act on the target muscle groups.

[0006] How to provide a rehabilitation device that can realize multi-joint combined training of the upper limb shoulder, elbow and wrist joints and can assist in stimulating the muscles in specific parts has become an urgent problem to be solved.

[0007] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0023] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0024] Example 1

[0025] This embodiment provides an upper limb multi-joint rehabilitation training device, such as Figure 1 As shown, it includes a platform support 1, a column 2 arranged on the platform support 1, and a rehabilitation training component fixed on the column 2.

[0026] In one embodiment, the column 2 is L-shaped, the longitudinal rod of the L-shaped column 2 is fixed on the platform bracket 1, and the first connecting rod 3 is installed at the lower end of the transverse rod of the L-shaped column 2.

[0027] It can be understood that the arrangement of the upright column 2 facilitates the arrangement of the rehabilitation training component on the platform bracket 1 .

[0028] The rehabilitation training assembly includes a first connecting rod 3 arranged along a first direction, a second connecting rod 5 arranged along a second direction, and a third connecting rod 7 arranged along a third direction, wherein the first connecting rod 3 is connected to the column 2 via a first angle adjustment device 4; the second connecting rod 5 is connected to the first connecting rod 3 via a second angle adjustment device 6; and the third connecting rod 7 is connected to the second connecting rod 5 via a third angle adjustment device 8;

[0029] A forearm support ring 9 is installed at one end of the third connecting rod 7 away from the second connecting rod 5;

[0030] A fourth angle adjustment device 10 is installed on the side of the forearm support ring 9 away from the third connecting rod 7 , and a wrist support ring 11 is installed on the fourth angle adjustment device 10 .

[0031] The first angle adjustment device 4 is used to realize the rotation of the first connecting rod 3 relative to the column 2, thereby realizing the movement of the shoulder joint in horizontal abduction and horizontal adduction; wherein, horizontal abduction of the shoulder joint refers to the upper arm being lifted outward away from the side of the body, with a normal range of 0 to 30 degrees; horizontal adduction of the shoulder joint refers to the upper arm moving forward through the body toward the opposite limb, with a normal range of 0 to 130 degrees.

[0032] In one embodiment, the first angle adjustment device 4 includes a first adjustment knob, a threaded through-hole extending through the first connecting rod 3, and a rotating sleeve. The bottom of the first adjustment knob passes through the threaded through-hole via a screw, and the rotating sleeve is disposed within the interior of the column 2. Specifically, when the first adjustment knob is loosened, the column 2 and the first connecting rod 3 are flexibly connected, enabling the shoulder joint to move in horizontal abduction and horizontal adduction.

[0033] It can be understood that, during use, the first angle adjustment device 4 fixes the horizontal abduction and horizontal adduction range of the shoulder joint at a specific angle.

[0034] The second angle adjustment device 6 is used to realize the movement of the shoulder joint in flexion and extension; wherein, shoulder flexion refers to the upper arm extending and lifting forward of the body, with a normal range of 0 to 180 degrees; shoulder extension refers to the upper arm extending and lifting backward of the body, with a normal range of 0 to 60 degrees.

[0035] In one embodiment, the second angle adjustment device 6 includes a second adjustment knob, a connector disposed along a second direction at the movable end of the first connecting rod 3, and a clamp disposed at one end of the second connecting rod 5 for securing the connector. Both the clamp and the connector are provided with threaded holes. A screw at the bottom of the second adjustment knob passes through the threaded holes from one side of the clamp and is locked with a nut disposed on the other side of the clamp. Specifically, when the second adjustment knob is loosened, the second connecting rod 5 is movably connected to the first connecting rod 3, enabling movement of the shoulder joint in flexion and extension.

[0036] It can be understood that, during use, the shoulder joint is fixed at a specific angle in flexion and extension by the second angle adjustment device 6 .

[0037] The third angle adjustment device 8 is used to achieve elbow flexion and extension (flexion and extension) of the elbow joint; wherein the range of flexion and extension is from 0 to 150 degrees.

[0038] In one embodiment, the third angle adjustment device 8 includes a third adjusting knob and a mounting groove arranged at the other end of the second connecting rod 5 for placing the third connecting rod 7, and threaded holes are arranged on both sides of the mounting groove and on the third connecting rod 7; the screw at the bottom of the third adjusting knob passes through the threaded holes in sequence from one side of the mounting groove, and is locked with a nut arranged on the other side of the mounting groove.

[0039] Specifically, when the third adjusting knob is loosened, the third connecting rod 7 and the second connecting rod 5 are movably connected, and the flexion and extension (flexion and extension) of the elbow joint can be achieved.

[0040] The fourth angle adjustment device 10 is used to realize wrist joint flexion, extension, radial deviation and ulnar deviation.

[0041] In one embodiment, the fourth angle adjustment device 10 includes a fourth adjustment knob, a first connecting plate mounted on the forearm support ring 9, and a second connecting plate mounted on the bottom of the wrist support ring 11. The first connecting plate is provided with a threaded through-hole. The bottom of the fourth adjustment knob is disposed within the interior of the second connecting plate via a screw extending through the threaded through-hole. Specifically, when the fourth adjustment knob is loosened, the wrist support ring 11 and the forearm support ring 9 are flexibly connected, enabling flexion and extension (flexion and extension) or axial rotation (radial deviation and ulnar deviation) of the wrist joint.

[0042] Specifically, whether to realize flexion and extension or axial rotation movement of the wrist joint depends on the posture of the wrist joint placed on the wrist support ring 11. When the patient places the wrist joint with the back of the hand facing up, the radial deviation and ulnar deviation movement of the wrist joint are realized; when the patient places the wrist joint with the side of the hand facing up, the flexion and extension movement of the wrist joint are realized.

[0043] When using the upper limb multi-joint rehabilitation training device for functional electrical stimulation, the first angle adjustment device 4, the second angle adjustment device 6, the third angle adjustment device 8, and the fourth angle adjustment device 10 are set at specific angles based on the patient's actual condition. The patient's upper arm is secured to the second connecting rod 5 with a bandage to provide support for the patient's upper arm; the patient's forearm is secured to the forearm support ring 9 with a bandage to provide support for the patient's forearm; and the patient's wrist joint is secured to the wrist support ring 11 with a bandage to provide support for the patient's wrist joint. Functional electrical stimulation is then used to stimulate specific muscles, achieving the purpose of muscle rehabilitation training at specific angles and locations.

[0044] It is understandable that the forearm support ring and the wrist support ring are also provided with a fixing hole 18 for a strap to pass through. During use, the strap is utilized to pass through the fixing hole 18 to achieve the fixation of the forearm and wrist.

[0045] Of course, for patients whose upper limb functions are only partially impaired, the upper limb multi-joint rehabilitation training device can also be used for active training. During active training, the angle adjustment device corresponding to the joint that the patient wants to train is controlled to be in an active state.

[0046] For example, by fixing the third angle adjustment device 8 and the fourth angle adjustment device 10 and making the first angle adjustment device 4 and the second angle adjustment device 6 active, horizontal adduction, horizontal abduction, flexion and extension training of the shoulder joint can be achieved.

[0047] For another example, by fixing the first angle adjustment device 4, the second angle adjustment device 6, and the fourth angle adjustment device 10, and making the third angle adjustment device 8 active, the elbow joint can be trained.

[0048] For another example, by fixing the first angle adjustment device 4, the second angle adjustment device 6, and the third angle adjustment device 8, and making the fourth angle adjustment device 10 active, the wrist joint can be trained.

[0049] It is understandable that the above three examples are only for illustrating the usage of active training, and the actual active training types are not limited to the above three.

[0050] It can be understood that the first angle adjustment device 4, the second angle adjustment device 6, the third angle adjustment device 8 and the fourth angle adjustment device 10 are not limited to the above structures.

[0051] Furthermore, in order to improve the patient's comfort, the wrist support ring 11 and the forearm support ring 9 are both rubber rings.

[0052] In addition, the second connecting rod 5 and the third connecting rod 7 are both carbon fiber connecting rods; the first adjusting knob, the second adjusting knob, the third adjusting knob and the fourth adjusting knob are all carbon fiber adjusting knobs, thereby reducing the weight of the rehabilitation training component and alleviating the burden on the patient.

[0053] Furthermore, a length adjusting device 12 is provided at one end of the third connecting rod 7 away from the second connecting rod 5 , and the forearm supporting ring 9 is mounted on the length adjusting device 12 .

[0054] The position of the forearm support ring 9 is adjusted by the length adjustment device 12 to adapt to different patients and to fix the forearm support ring 9 .

[0055] In one embodiment, the length adjustment device 12 includes a fifth adjustment knob, the bottom of which is screwed inside the third connecting rod 7. During use, the fifth adjustment knob is screwed in and out to adjust the position of the screw inside the third connecting rod 7, thereby adjusting the distance between the forearm support ring 9 and the second connecting rod 5. Preferably, the fifth adjustment knob is a carbon fiber adjustment knob.

[0056] Example 2

[0057] The difference between this embodiment and embodiment 1 is that: Figure 2 As shown, the wrist support ring 11 is further provided with a finger support column 13.

[0058] When in use, the patient's fingers are fixed to the finger support column 13 in an extended state by a strap, thereby enhancing the patient's operating stability, allowing the patient to use the muscles of the entire upper limb to the greatest extent possible to complete rehabilitation training, and improving the patient's rehabilitation effect.

[0059] It is understandable that the finger support column 13 can be as follows Figure 2 As shown, it is arranged on the side of the wrist support ring 11, and can also be arranged in the middle part. The position of the finger support column 13 is not particularly limited.

[0060] Example 3

[0061] The difference between this embodiment and embodiment 1 is that: Figure 3-4 As shown, a screen placement slot 14 is also provided on the platform bracket 1, and the end of the screen bracket 15 close to the finger support column 13 is hinged to the screen placement slot 14, and the end of the screen bracket 15 away from the finger support column 13 is connected to the screen placement slot 14 through a screen angle adjustment device.

[0062] During use, the angle of the screen bracket 15 is adjusted by the screen angle adjustment device so that the patient can operate the screen more conveniently. After the angle adjustment is completed, the smart terminal is placed on the screen bracket 15 and rehabilitation training begins.

[0063] Of course, the smart terminal can also be placed on the screen bracket 15 first, and then the angle of the screen bracket 15 can be adjusted by the screen angle adjustment device; after the angle adjustment is completed, the rehabilitation training can be started.

[0064] In one embodiment, the screen angle adjustment device includes a plurality of angle adjustment holes 16 arranged in the screen placement groove 14 and a support column 17 adapted to the angle adjustment holes 16, and the distances between any two angle adjustment holes 16 and one end of the screen placement groove 14 and the screen bracket 15 are hinged are different; when in use, the angle of the screen bracket 15 is adjusted by placing the support column 17 in different angle adjustment holes 16.

[0065] In another embodiment, in one embodiment, the screen angle adjustment device includes a support column 17 hinged in the screen placement groove 14, and a plurality of angle adjustment holes 16 are provided on the back of the screen bracket 15 corresponding to the support column 17. When in use, the angle of the screen bracket 15 is adjusted by placing the support column 17 into different angle adjustment holes 16.

[0066] It is understandable that the screen angle adjustment device may also be in other forms.

[0067] In one embodiment, the smart terminal is an entertainment terminal, which facilitates entertainment activities during rehabilitation training and reduces the boredom of rehabilitation training.

[0068] In another embodiment, the smart terminal has built-in rehabilitation training software, and patients can independently select different rehabilitation training tasks according to their upper limb multi-joint rehabilitation exercise level, and control their fingers to slide on the smart terminal for training. At the same time, they can understand the degree and effect of rehabilitation training in real time, effectively improve the patient's enthusiasm for rehabilitation, and provide patients with a comfortable and efficient rehabilitation system.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
