[0025] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0026] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 8 The upper limb rehabilitation training device according to a preferred embodiment of this application will be described in detail below.

[0029] The upper limb rehabilitation training equipment includes a first carrier 10, a second carrier 20, and at least one operating component 30.

[0030] The first carrier 10 includes a first device body 11 and a first light generator 12. The first light generator 12 is mounted on the first device body 11 and is configured to form a visible light spot at any position on the surface of the first device body 11.

[0031] The second carrier 20 includes a second device body 21 and at least one mounting member 22, which is pivotally mounted to the second device body 21. The operating member 30 is connected to the mounting member 22. When the first light generator 12 forms a subsequent visible light spot on the surface of the first device body 11 at a position different from the previous visible light spot, the operating member 30 is manipulated by the patient's upper limb to drive the mounting member 22 to pivot in a direction parallel to the position of the previous visible light spot and extending towards the position of the subsequent visible light spot.

[0032] When the second carrier 20 is placed horizontally, the operating component 30 is vertically assembled to the mounting member 22. With the operating component 30 initially positioned vertically, the first light generator 12 forms a first visible light spot at any position on the surface of the first device body 11. Then, the first light generator 12 forms a second visible light spot at the remaining positions on the surface of the first device body 11, with the first visible light spot as the origin. The patient can determine the correct swing direction of the operating component 30 based on the positions of the two visible light spots. The patient then uses their upper limbs to manipulate the operating component 30, causing the mounting member 22 to swing in a direction parallel to the first visible light spot and extending towards the second visible light spot. For example, the first light generator 12 forms a second visible light spot on the surface of the first device body 11 to the left of the first visible light spot, with the first visible light spot as the origin. The patient then knows the correct swing direction and uses their upper limbs to manipulate the operating component 30, causing the mounting member 22 to swing to the left. During this process, the patient uses the fingers of the upper limb requiring rehabilitation training to grasp the operating component 30, and then uses wrist twisting to move the operating component 30, causing the connecting component 22 to swing, thereby achieving rehabilitation training for the patient's upper limb. In this way, the first light generator 12 continuously forms multiple visible light spots on the surface of the first device body 11 to form a light path. Guided by the light path, the patient uses the wrist of the upper limb to bend in a preset direction at a preset angle to perform different degrees of exercise on the patient's upper limb. It can also be used by patients with different injuries.

[0033] In one embodiment, the second device body 21 forms a spherical groove 2101 and a communication port 2102 communicating with the spherical groove 2101. The mounting member 22 has a mounting portion 2111 and a direction adjustment portion 2112. One end of the mounting portion 2111 is connected to the direction adjustment portion 2112, wherein the direction adjustment portion 2112 is rotatably mounted in the spherical groove 2101, and the mounting portion 2111 extends out of the spherical groove 2101 through the communication port 2102. One end of the mounting portion 2111 extending out of the spherical groove 2101 is assembled with the operating member 30. When the patient holds and moves the operating member 30, the operating member 30 drives the direction adjustment portion 2112 to rotate in any direction within the spherical groove 2101 via the mounting portion 2111, causing the operating member 30 to swing relative to the second device body 21.

[0034] It is understood that the orientation adjustment part 2112 is implemented as a sphere or a hemisphere, and the size of the connecting port 2102 is smaller than the cross-sectional size of the orientation adjustment part 2112 through the center of the sphere. In this way, the edge of the connecting port 2102 can prevent the mounting member 22 from being pulled out of the spherical groove 2101.

[0035] Preferably, the second device body 21 forms a recessed groove 2103 with its opening facing the same direction as the communication port 2102. The bottom wall of the recessed groove 2103 formed by the second device body 21 is recessed downward to form the spherical groove 2101. The assembly part 2111 extends into the recessed groove 2103 from the communication port 2102. The operating member 30 extends into the recessed groove 2103 through an opening communicating with the recessed groove 2103 and is assembled with the assembly part 2111. The edge of the opening communicating with the recessed groove 2103 limits the swing range of the operating member 30 to prevent secondary injury caused by excessive wrist twisting angle during rehabilitation training.

[0036] Furthermore, the upper limb rehabilitation training device is provided with multiple operating components 30. The second carrier 20 is provided with multiple mounting components 22, and the second device body 21 forms multiple sinkholes 2103 and spherical grooves 2101, the number of which is the same as the number of mounting components 22. The multiple operating components 30 are respectively assembled with the multiple mounting components 22.

[0037] In a preferred embodiment, the opening diameters of the plurality of sinking troughs 2103 that are connected to each other gradually increase, such as... Figure 7 and Figure 8As shown. In this way, the edges of the openings of the multiple sinking grooves 2103 can limit the swing range of each of the operating elements 30 to be different. The operating element 30 with the corresponding swing range can be selected according to the patient's condition, so that the upper limb rehabilitation training device can be used by patients with different conditions.

[0038] Preferably, the mounting member 22 is implemented as a damping ball head to increase the resistance when the patient uses the upper limb that needs rehabilitation training to manipulate the movement of the operating member 30, so as to facilitate strength training of the upper limb that needs rehabilitation training.

[0039] As another preferred embodiment, the plurality of mounting members 22 are each configured with a damping ball head with different resistance, so that the resistance to be overcome when manipulating each of the operating members 30 is different. The operating member 30 is selected according to the patient's condition and fitted with the corresponding mounting member 22, allowing the upper limb rehabilitation training device to be used by patients with different conditions.

[0040] Furthermore, the upper limb rehabilitation training device also includes a posture detection component 40, a controller 50, a feedback mechanism 60, and a position detection mechanism 70.

[0041] The first light generator 12 is controllably connected to the controller 50. The posture detection component 40 is mounted on the operating element 30 or the mounting component 22, and the posture detection component 40 is communicatively connected to the controller 50 to monitor whether the operating element 30 is manipulated by the patient to swing in the correct direction. The feedback mechanism 60 includes a first feedback component 61, which is controllably connected to the controller 50. The controller 50 controls the first feedback component 61 to issue corresponding feedback information based on the monitoring results of the posture detection component 40, so as to inform the patient whether the training action is correct.

[0042] In other words, after the patient manipulates the operating component 30 to move according to the two visible light spots emitted by the first light generator 12, the posture detection component 40 transmits the movement direction of the operating component 30 to the controller 50. If the patient manipulates the operating component 30 in the wrong direction, the controller 50 controls the first feedback component 61 to generate a feedback signal indicating an incorrect action, informing the patient. Preferably, if the patient manipulates the operating component 30 in the correct direction, the controller 50 controls the first feedback component 61 to generate a feedback signal indicating a correct action, informing the patient.

[0043] As an example, the first feedback component 61 may be implemented as a light generator or a sound generator. Alternatively, the first feedback component 61 may also be implemented as a vibrator. The first feedback component 61 is mounted on the second device body 21. It is understood that when the patient performs upper limb rehabilitation training, the upper limb will contact the second device body 21, allowing the patient to perceive the correctness of the rehabilitation training movements through touch.

[0044] Preferably, the first light generator 12 can be controlled by the controller 50 to form visible light spots of different colors at any position on the surface of the first device body 11.

[0045] Furthermore, the second carrier 20 also includes a second light generator 23, which is mounted on the second device body 21, and the second light generator 23 can be controlled by the controller 50 to form visible light spots of different colors on the surface of the second device body 21 at positions corresponding to each of the mounting members 22.

[0046] When the first light generator 12 forms a visible light spot of a certain color at any position on the surface of the first device body 11, at least one of the multiple visible light spots of different colors formed by the second light generator 23 on the surface of the second device body 21 is the same color as the visible light spot formed on the surface of the first device body 11.

[0047] The patient selects the operating component 30 connected to the mounting bracket 22 with the same color as the visible light spot formed by the first light generator 12 on the surface of the first device body 11. When the first light generator 12 forms a subsequent visible light spot on the surface of the first device body 11 at a different position than the previous visible light spot, the patient manipulates the operating component 30 to drive the mounting bracket 22 to swing in a direction parallel to the position of the previous visible light spot towards the position of the subsequent visible light spot. When the color of the visible light spot formed by the first light generator 12 on the surface of the first device body 11 changes, the patient changes the corresponding operating component 30 according to the changed color. During the above process, the patient needs to use rehabilitation training for the fingers, wrists, and arms of the upper limbs, which trains the upper limb coordination and limb reaction ability while exercising the upper limb strength, so that the patient's upper limbs can receive comprehensive training.

[0048] In a preferred embodiment, the operating element 30 is detachably plugged into the mounting element 22.

[0049] Specifically, the assembly part 2111 forms an assembly structure 21111, and the operating member 30 forms a mounting structure 31. Either the assembly structure 21111 or the mounting structure 31 is implemented as a groove, and the other as a protrusion. The assembly structure 21111 is inserted into the mounting structure 31. The operating member 30 is assembled to the assembly part 2111 in such a way that the mounting structure 31 is inserted into the assembly structure 21111.

[0050] Preferably, the first device body 11 forms a plurality of placement structures 1101 arranged in an array, and the first light generator 12 is configured to form visible light spots on the surface of the first device body 11 at corresponding positions of each of the placement structures 1101. The operating member 30 is detachably plugged into the placement structure 1101 formed by the first device body 11, and the operating member 30 can be manipulated by the patient to be moved back and forth between the placement structure 1101 formed by the first device body 11 and the assembly structure 21111.

[0051] In one embodiment, the patient selects and removes the operating member 30, which is inserted into the mounting member 22 of the same color, based on the color of the visible light spot formed by the first light generator 12 on the surface of the first device body 11. The operating member 30 is then moved to the placement structure 1101 corresponding to the position of the visible light spot. During this process, the operating member 30 remains grasped by the patient's upper limb and is controlled to move between the first carrier 10 and the second carrier 20. Therefore, the range of motion of the patient's upper limb and the angles of motion between the joints are increased, allowing the upper limb rehabilitation training device to be used by patients with different conditions.

[0052] As an example, the placement structure 1101 is implemented as a groove or a protrusion.

[0053] Preferably, the first device body 11 includes an upper housing 111 and a lower housing 112, with the first device body 111 being coveredly mounted on the lower housing 112. The placement structure 1101 is formed on the upper housing 111.

[0054] It is worth mentioning that the position detection mechanism 70 includes a first position detection component 71, which is communicatively connected to the controller 50. The first position detection component 71 is mounted on the second device body 21 and is used to detect whether the patient has correctly removed the operating component 30. The controller 50 can control the first feedback component 61 to issue corresponding feedback information based on the detection result of the first position detection component 71, so as to inform the patient whether the training action is correct.

[0055] Preferably, the position detection mechanism 70 further includes a second position detection component 72, which is communicatively connected to the controller 50. The second position detection component 72 is mounted on the first device body 11 and is used to detect whether the position of the operating member 30 inserted into the placement structure 1101 is correct.

[0056] The feedback mechanism 60 further includes a second feedback component 62, which is controllably connected to the controller 50. The controller 50 controls the second feedback component 62 to issue corresponding feedback information based on the detection result of the second position detection component 72, so as to inform the patient whether the training action is correct.

[0057] In other words, after the patient inserts the operating component 30 into the placement structure 1101, the second position detection component 72 transmits the insertion position of the operating component 30 to the controller 50. If the patient manipulates the operating component 30 to the incorrect insertion position, the controller 50 controls the second feedback component 62 to generate a feedback signal indicating an incorrect action, thereby informing the patient. Preferably, if the patient manipulates the operating component 30 to the correct insertion position, the controller 50 controls the second feedback component 62 to generate a feedback signal indicating a correct action, thereby informing the patient.

[0058] As an example, the second feedback component 62 can be implemented as a light generator or a sound generator. Alternatively, the second feedback component 62 can also be implemented as a vibrator. The second feedback component 62 is mounted on the first device body 11. It is understood that when the patient performs upper limb rehabilitation training, the upper limb will come into contact with the first device body 11 and the operating element 30, allowing the patient to perceive the correctness of the rehabilitation training movements through touch.

[0059] It is worth mentioning that when the first feedback component 61 and / or the second feedback component 62 are implemented as a voice announcer in a sound generator, the voice announcer can guide the patient through training via voice, which will not be described in detail here.

[0060] Preferably, the first position detection component 71 and the second position detection component 72 can be implemented as a weight sensor, a proximity sensor, etc.

[0061] Furthermore, the upper limb rehabilitation training device also includes a power supply component 80, wherein the first light generator 12 and the second light generator 23 are both electrically connected to the power supply component 80 to provide power to the first light generator 12 and the second light generator 23.

[0062] As an example, the power supply component 80 is implemented as a storage battery.

The advantages of this application have been fully and effectively implemented.
