[0026] This specific embodiment is an upper limb fixation treatment device for a rehabilitation therapy bed, and its structural schematic diagram is shown below. Figures 1-8 As shown.

[0027] The upper limb fixation treatment device includes a support plate 1, a hook 2 mounted on the support plate 1, a retractable upper arm support plate 3 mounted on the support plate 1, a retractable forearm support plate 4 mounted on the retractable end of the upper arm support plate 3, a first drive assembly 5 provided on both the support plate 1 and the upper arm support plate 3, the first drive assembly 5 being used to control the upper arm support plate 3 and the forearm support plate 4 to swing up and down, a connecting block 6 provided on the first drive assembly 5, a second drive assembly 7 provided inside the connecting block 6, the second drive assembly 7 being used to control the upper arm support plate 3 and the forearm support plate 4 to swing left and right, an arm support frame 8 fixedly connected to both the upper arm support plate 3 and the forearm support plate 4, and a strap (not shown in the figure) for fixing the arm is mounted on the arm support frame 8.

[0028] Two hooks 2 are provided, and the two hooks 2 are fixedly connected to the two ends of the support plate 1 respectively. A threaded rod 9 is threadedly connected to the hook 2. One end of the threaded rod 9 is rotatably connected to the connecting plate 10 through a bearing. The other end of the threaded rod 9 is fixedly connected to the handwheel 11. The hook 2 is suspended on the foot of the treatment bed. Then, the threaded rod 9 is rotated clockwise by the handwheel 1. Since the threaded rod 9 is threadedly connected to the hook 2, the threaded rod 9 can move towards the treatment bed during the rotation. During the movement, the threaded rod 9 can drive the connecting plate 10 to move closer to the foot of the bed until the connecting plate 10 is tightly abutted against the foot of the treatment bed. At this time, the position of the hook 2 can be limited.

[0029] The end of the forearm support plate 4 away from the upper arm support plate 3 can be equipped with a detachable hand-shaped accessory as needed, which facilitates stretching for patients with dystonia of the wrist and fingers.

[0030] Both the upper arm support plate 3 and the forearm support plate 4 are telescopic rods, and these telescopic rods include, but are not limited to, electrically operated telescopic rods. By setting the upper arm support plate 3 and the forearm support plate 4 as telescopic rods, the lengths of the upper arm support plate 3 and the forearm support plate 4 can be adjusted, thus making them suitable for different patients.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the first drive assembly 5 includes a housing 51, which can both prevent dust and provide protection. The side of the housing 51 away from the support plate 1 is an open structure. A U-shaped seat 52 is fixedly connected to the inner bottom wall of the housing 51. A first motor 53 is fixedly connected to the middle of the U-shaped seat 52. The output shaft of the first motor 53 passes through the U-shaped seat 52 and extends to the outside of the U-shaped seat 52. A first gear 54 is fixedly connected to the output shaft of the first motor 53. A second gear 55 is meshed above the first gear 54. A rotating shaft 56 is fixedly connected to the middle of the second gear 55. The rotating shaft 56 is rotatably connected to the U-shaped seat 52 through a bearing. A connecting shaft 57 is fixedly connected to the middle of the rotating shaft 56. The end of the connecting shaft 57 away from the rotating shaft 56 is fixedly connected to the connecting block 6.

[0032] When the first motor 53 is started and drives the first gear 54 to rotate clockwise, the first gear 54 can drive the second gear 55, which is meshed with it, to rotate during the rotation. The second gear 55 can drive the rotating shaft 56, which is fixedly connected to it, to rotate during the rotation. The rotating shaft 56 can drive the connecting shaft 57 to rotate downward during the rotation.

[0033] When the first motor 53 is started and drives the first gear 54 to rotate counterclockwise, the first gear 54 can drive the second gear 55, which is meshed with it, to rotate during the rotation. The second gear 55 can drive the rotating shaft 56, which is fixedly connected to it, to rotate during the rotation. The rotating shaft 56 can drive the connecting shaft 57 to rotate upward during the rotation.

[0034] Therefore, the first motor 53 can drive the connecting shaft 57 to rotate up or down.

[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the interior of the connecting block 6 is a hollow structure. The second drive assembly 7 includes a second motor 71 fixedly connected to the bottom wall of the connecting block 6. The output shaft of the second motor 71 is fixedly connected to a third gear 72, and the external of the third gear 72 is meshed with an internal gear 73.

[0036] Both the third gear 72 and the internal gear 73 extend to the outside of the connecting block 6. The top of the internal gear 73 is higher than the top of the third gear 72, and the top of the internal gear 73 is fixedly connected to the support plate 74. This arrangement allows for a gap between the top of the third gear 72 and the bottom of the support plate 74, which satisfies the rotation of the third gear 72.

[0037] When the second motor 71 is started and drives the third gear 72 to rotate clockwise, the third gear 72 can drive the internal gear 73 that meshes with it to rotate during the rotation process. The internal gear 73 can drive the support plate 74 to rotate to the left during the rotation process.

[0038] When the second motor 71 is started, it drives the third gear 72 to rotate counterclockwise. During the rotation, the third gear 72 can drive the internal gear 73 that meshes with it to rotate. During the rotation, the internal gear 73 can drive the support plate 74 to rotate to the right.

[0039] Therefore, the second motor 71 can drive the pallet 74 to rotate to the left or right.

[0040] An arc-shaped groove is provided on the side of the support plate 74 away from the internal gear 73. The arc-shaped groove facilitates the fixed installation of the support plate 74 with the upper arm support plate 3 and the forearm support plate 4.

[0041] The side of the housing 51 away from the support plate 1 is set as an open structure, which provides rotation space for the connecting shaft 57 to rotate up or down.

[0042] The housing 51 of the first drive assembly 5 on the support plate 1 is fixedly connected to the support plate 1, and the support plate 74 of the second drive assembly 7 on the connecting block 6 of the first drive assembly 5 is fixedly connected to the upper arm support plate 3. When the first motor 53 can drive the connecting shaft 57 to rotate upward or downward, the connecting shaft 57 can drive the connecting block 6 fixedly connected to it to rotate upward or downward. When the connecting block 6 can drive the upper arm support plate 3 to rotate upward or downward during the rotation, the upper arm support plate 3 can be driven to rotate left or right under the drive of the second motor 71. Therefore, the upper arm support plate 3 can rotate upward, downward, left, and right.

[0043] The housing 51 of the first drive assembly 5 on the upper arm support plate 3 is fixedly connected to the telescopic end of the upper arm support plate 3, and the support plate 74 of the second drive assembly 7 on the connecting block 6 on the first drive assembly 5 is fixedly connected to the telescopic end of the forearm support plate 4. When the first motor 53 can drive the connecting shaft 57 to rotate upward or downward, the connecting shaft 57 can drive the connecting block 6 fixedly connected to it to rotate upward or downward. When the connecting block 6 can drive the forearm support plate 4 to rotate upward or downward during the rotation, the forearm support plate 4 can be driven to rotate left or right under the drive of the second motor 71. Therefore, the forearm support plate 4 can rotate upward, downward, left, and right.

[0044] In summary: placing the patient's upper limb on the arm support frame 8 allows the upper limb fixation treatment device to provide fixation and support for the entire upper limb, reducing the impact of gravity on the upper limb and reducing the probability of shoulder dislocation on the affected shoulder.

[0045] This upper limb fixation treatment device allows both the upper arm support plate 3 and the forearm support plate 4 to move up and down and left and right. When the patient's upper limb is placed on the arm support frame 8, it can mimic the shoulder joint's abduction, flexion, and horizontal adduction, thereby effectively stretching the chest and shoulder muscles. At the same time, the position of the affected hand can be adjusted to effectively promote blood return.

[0046] The upper limb fixation treatment device allows both the upper arm support plate 3 and the forearm support plate 4 to move up and down and left and right. When the patient's upper limb is placed on the arm support frame 8, it can mimic the flexion and extension of the elbow joint, which can effectively pull the tension of the affected upper limb.

[0047] The support plate 1 can be suspended at the foot of the treatment bed by the hook 2. When the upper limb fixation treatment device is added to the rehabilitation treatment bed, multiple muscle and joint stretching can be performed at the same time, which can effectively reduce labor costs and alleviate the economic burden on patients.

[0048] The upper limb fixation treatment device allows both the upper arm support plate 3 and the forearm support plate 4 to move up and down and left and right, thereby allowing the upper limb fixation treatment device to be adjusted so that the upper limb distal position is high and the proximal position is low, promoting blood return in the upper limb.

[0049] Therefore, this utility model can control the upper arm support plate 3 and the forearm support plate 4 to move up and down and left and right through the first drive component 5 and the second drive component 7, which can drive the upper limbs to exercise.

[0050] All technical features in this embodiment can be freely combined according to actual needs.

[0051] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
