[0033] The utility model discloses a kind of stroke upper limb treatment devices based on task-oriented training, as shown in Figure 1As shown, the stroke upper limb treatment device of this utility model mainly includes a pair of bases 1, a pair of lower support rods 2 respectively disposed on the bases 1, a U-shaped support frame 3 disposed on the lower support rods 2, a lower connecting rod 4 transversely disposed between the two lower support rods 2, and an upper connecting rod 5 transversely disposed between the U-shaped support frames 3. The U-shaped support frame 3 is formed by connecting the upper rod and the two side rods. The lower ends of the two side rods are respectively connected to the upper ends of the two lower support rods 2 through rotating joints 6, so as to be able to rotate back and forth. The rotating joint 6 can be a rotating cylinder or a similar component. If a rotating cylinder is used, the angle range of the back and forth rotation can be set as needed. In this way, when the patient places or grasps the upper rod of the U-shaped support frame 3, he can push the U-shaped support frame 3 to rotate back and forth, thereby performing shoulder flexion and extension training treatment. The lower support rods 2, the upper connecting rods 5, the lower connecting rods 4, and the two side rods and the upper rod of the U-shaped support frame 3 can all adopt a telescopic adjustment structure, which can be adjusted in height and width. Of course, in order to better fix the patient's upper limb and to enable more targeted training, the treatment device also includes upper limb fixation accessories mounted on the U-shaped support frame 3.

[0034] Example 1

[0035] like Figures 2-4 As shown, the upper limb fixation accessory in this embodiment includes a supine position accessory, which includes arm supports 7 for fixing the upper arm and forearm respectively. The arm supports 7 are equipped with Velcro straps 8, and the back of the arm supports 7 is also equipped with locking clips 9 for fixing to the side rods of the U-shaped support frame 3, which can be locked in place with bolts. For patients requiring bed rest in the early stages of stroke and Brunnstrom's first-stage upper limb fixation, based on neurodevelopmental theory, limb recovery after stroke progresses from proximal to distal. Therefore, for patients in the flaccid paralysis stage, this accessory can be used as an auxiliary tool for training and treating shoulder muscle strength in a supine position. The treatment device is placed beside the bed and adjusted to a suitable height. The patient's affected upper arm and forearm are fixed to the side rods of the U-shaped support frame 3 using the two arm supports 7. Through training methods for the shoulder muscles within a set range, the muscle strength of the shoulder flexion and retraction-related muscles is induced or strengthened, thereby improving and strengthening shoulder function.

[0036] Example 2

[0037] like Figure 2 As shown, the upper limb fixation accessory in this embodiment is based on Embodiment 1, with the addition of a gripper 10. Specifically, a support plate 11 is connected to the front of the arm support 7 used to fix the forearm, and the gripper 10 is provided on the support plate 11. The difference from Embodiment 1 is that this embodiment is for patients with hand dysfunction who are unable to perform movements, allowing them to grasp the gripper 10 during shoulder flexion and extension training. Embodiment 1, on the other hand, adds some hand training movements while performing shoulder flexion and extension.

[0038] Example 3

[0039] like Figures 5-7 As shown, the upper limb fixation accessory in this embodiment includes a shoulder flexion and extension accessory, which includes a support plate 11, an arm rest 7 mounted on the support plate 11, a Velcro strap 8 on the arm rest 7, and a locking clip 9 on the back of the support plate 11 for fixing to the upper rod of the U-shaped support frame 3. For patients whose sitting balance is at level 2 and whose upper limb Brunnstrom has reached stage II, the effect of muscle strength training in the supine position is already poor. Therefore, with the patient in a sitting position, the affected forearm is fixed to the arm rest 7, and with the assistance of a therapist, a sitting shoulder flexion-elbow extension compound push-pull training movement is performed, which can improve the upper limb coordination of stroke patients, enhance shoulder and elbow muscle strength and stability, promote functional recovery, prevent shoulder dislocation and contracture, and activate the nerves on the paralyzed side.

[0040] Example 4

[0041] like Figure 8 As shown in Example 2, based on Example 3, a gripper 10 is added to the support plate 11 and in front of the arm support 7, which is also suitable for patients with hand dysfunction to grip when performing shoulder flexion-elbow extension training.

[0042] Example 5

[0043] like Figures 9-10 As shown, the upper limb fixation accessory in this embodiment includes a shoulder abduction and adduction accessory, which includes a panel 12 located in the middle of the U-shaped support frame 3, a movable groove 13 formed on the panel 12, an arm support 7, and a split plate 14 connected to the front of the arm support 7. The panel 12 is connected and fixed to the two side rods of the U-shaped support frame 3 by means of buckles on both sides. The back of the split plate 14 has a sliding structure that cooperates with the movable groove 13, such as using a magnetic suction type or a slider, pulley and groove cooperation. The arm support 7 and the split plate 14 are also provided with magic straps 8, which are used to fix the patient's forearm and hand on the affected side, respectively, and the finger spreader 14 can spread the patient's fingers. The movable groove 13 can usually be designed as a cross shape as shown in the figure. For patients with Brunnstrom stage 3 upper limb stroke, the bottleneck period often occurs in the transition from stage 3 to stage 4. By using the accessories in this embodiment, patients can perform small-range, high-frequency movements up, down, left, and right within a range that does not induce abnormal flexion patterns. This can activate the muscles around the shoulder joint, improve the range of motion of the shoulder joint, and prevent contractures. Furthermore, by maintaining a 90-degree shoulder flexion and elbow extension posture, patients can maintain static or dynamic stability, thereby enhancing control of the shoulder and elbow joints.

[0044] Example 6

[0045] like Figures 11-13As shown, the upper limb fixing accessory in the embodiment includes a shoulder abduction and external rotation accessory, which includes an I-shaped support 18 horizontally arranged on the H-shaped support frame 3 and fixed at both ends with the H-shaped support frame 3, an elbow support 15 arranged on the support, a suction cup 16 arranged at the bottom of one base 1, a pulley 17 arranged at the bottom of the other base 1, and a magic band 8 arranged on the elbow support 15. For the shoulder pain and limited movement function of the upper limb of the patient caused by insufficient shoulder abduction and external rotation muscle strength, the accessory of the embodiment can be used to fix the forearm and elbow of the affected side of the patient on the elbow support 15, then the function of one side fixed and the other side slidable of the H-shaped support frame 3 is used for left and right swinging, and the therapist can also use auxiliary tools or markers to accurately limit the range of motion to achieve the training and treatment of shoulder abduction and external rotation. If muscle strength or endurance needs to be increased, sandbags can be worn on the distal end of the upper limb to increase the difficulty of treatment.

[0046] Embodiment 7

[0047] As Figure 14 shown, the same as embodiment 2, on the basis of embodiment 6, a gripping member 10 is additionally arranged on the I-shaped support in front of the elbow support 15, which is also suitable for the gripping of the patient with hand dysfunction during training.

[0048] However, those skilled in the art in the technical field should realize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application, as long as the changes and modifications of the above described embodiments are within the scope of the essential spirit of the present application, which will fall within the scope of the claims of the present application.
