Description

Technical Field

[0001] The present invention relates to the technical field of upper limb training, and in particular to an upper limb-based active and passive training device and method. Background Art

[0002] After treatment, patients generally experience limb dysfunction and need to rest in bed. However, long-term rest will also bring certain adverse reactions to the body, leading to physical weakness, which is not conducive to future recovery and a certain sub-health state. At the same time, for patients with minor injuries or who have recovered to a certain extent and do not need rest, a certain intensity of strength training is necessary. Otherwise, long-term bed rest will lead to muscle atrophy, joint stiffness, and even disuse paralysis of the patient's limbs, affecting the patient's health and not conducive to the patient's later recovery.

[0003] Rehabilitation training theory shows that the motor nerve and muscle function of the human body can be enhanced through exercise training, and for people with damaged motor nerves and muscles, they can gradually restore normal function through targeted exercise training. Rehabilitation training can be divided into passive training and active training. Passive training refers to the patient's exercise of the part to be rehabilitated under the traction of external force, and active training refers to the patient's independent exercise training of the part to be rehabilitated. The body parts for exercise rehabilitation training mainly include the upper limbs and lower limbs, and the upper limb motor function is most closely related to people's daily life activities.

[0004] In the field of upper limb motor rehabilitation training, there are currently three main types: physical equipment training, traction-type rehabilitation training robotic arms, and wearable traction robotic arms. However, the above devices are large in size and inconvenient to move, so the use scenarios of the rehabilitation devices are limited and their practicality is low. Summary of the invention

DETAILED DESCRIPTION Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figures 1 to 7 As shown, the active and passive training device based on upper limbs of the present invention includes a training device body 10, and an adjustment component 20 is arranged on the training device body 10. The functions of the adjustment component 20 include: selecting a training mode according to the patient's muscle strength evaluation result, and then adjusting to the corresponding training mode according to the adjustment component 20 to train the patient's upper limbs, thereby improving the efficiency and effect of the patient's upper limb training.

[0025] The training device body 10 includes a first shell 11, a second protective member 12 and a third protective member 13. The first shell 11 has an inner cavity 111. In one embodiment, the first shell 11, the second protective member 12 and the third protective member 13 are all circular, and the second protective member 12 is sleeved on the outer surface of the first shell 11, and the third protective member 13 is sleeved on the outer surface of the second protective member 12. It should be noted that the material of the second protective member 12 is made of sponge. In other embodiments, the second protective member 12 can also be made of a rubber pad to increase the softness of the training device body 10, avoid the user's hand discomfort caused by the hard shell when using the training device body 10, and increase the user's comfort during use. The material of the third protective member 13 is leather, and the third protective member 13 is sleeved on the outer surface of the second protective member 12, which is convenient for the removal of the third protective member 13, and the leather material has good wear resistance, which improves the service life of the training device body 10. In addition, a switch 14 and a charging port 15 are also provided at one end of the first shell 11.

[0026] The training device body 10 is provided with an adjustment component 20, which is installed inside the inner cavity 111. The adjustment component 20 includes a mounting plate 21 fixed to the inner surface of the inner cavity 111, and a controller 22, a stepper motor 23 and a circuit board 24 are installed on one side of the mounting plate 21. Specifically, the circuit board 24, the stepper motor 23 and the controller 22 are arranged in sequence from top to bottom, and the controller 22 can be used to control the stepper motor 23. The main shaft of the stepper motor 23 passes through one side of the mounting plate 21 and is fixedly connected with an eccentric component 25. The eccentric component 25 is in an arc shape, and the eccentric component 25 can be driven to rotate by the stepper motor 23. According to the position of the eccentric component 25, the training device body 10 is assisted or increased in resistance to assist the patient in exercising. In addition, a six-dimensional sensor 26 is also provided on one side of the eccentric component 25, and the six-dimensional sensor 26 is used to detect the relative position of the eccentric mechanism relative to the platform base.

[0027] It should be noted that when using the device, the user places the wrist on the outer surface of the third protective member 13 and then uses the strength of the wrist to push the device, thereby training the user's upper limbs.

[0028] like Figure 8 As shown, in a second aspect, the present invention further provides an active and passive training method based on upper limbs, comprising: S101: Obtain the patient's muscle strength level.

[0029] In one embodiment, before the patient uses the device, the patient's muscle strength needs to be tested first. Specifically, the doctor or rehabilitation expert uses a standard strength testing device, such as a manual dynamometer or an electronic dynamometer, to perform a series of strength tests on the patient's arm. The manual dynamometer is a traditional strength testing tool that measures the grip strength of the hand muscles through mechanical principles. It usually consists of a grippable handle and a meter that displays strength; the electronic dynamometer is a modern strength testing device that uses electronic sensors and a display screen to accurately measure and display strength data. Compared with the manual dynamometer, the electronic dynamometer has higher accuracy and convenience. For example, in the arm flexion test, the patient is asked to flex his arm, and the doctor applies resistance at the wrist until the patient can no longer flex it. By recording the maximum resistance value applied, the patient's arm flexion strength level can be evaluated, thereby obtaining the patient's current muscle strength level.

[0030] In one embodiment, a corresponding evaluation level can be obtained according to the patient's current muscle strength level, which can be divided into three levels: high, low and medium. Specifically, when the patient's muscle strength level is within the first threshold range, it is a high level; when the patient's muscle strength level is within the second threshold range, it is a low level; when the patient's muscle strength level is within the third threshold range, it is a medium level.

[0031] S102: Setting a training mode according to the patient's muscle strength level.

[0032] In one embodiment, the training mode includes a power-assist mode, a resistance mode and a normal mode. When the patient's current muscle strength level is at a high level, the resistance mode training is selected. When the patient's current muscle strength level is at a low level, the power-assist mode training is selected; when the patient's current muscle strength level is at a medium level, the normal mode training is selected. When the training mode is the power-assist mode, it means that the current patient's muscle strength cannot push the training device body 10 or push the training device body 10 at a slower speed, and the effect of training the patient's upper limbs cannot be achieved. When the training mode is the power-assist mode, it means that the current patient's muscle strength can push the training device body 10 to push the training device body 10 at a faster speed. At this time, the resistance to the training device body 10 should be increased to improve the effect of training the patient's upper limbs.

[0033] S103: Training the patient's upper limbs according to a training mode.

[0034] In one embodiment, during training, the patient places both arms on the top of the training device body 10, applies force F to the training device body 10, and causes the training device body 10 to generate a torque Mr, Mr=FR, so that the training device body 10 rolls. When the patient selects power training, the stepper motor drives the eccentric component 25 to rotate by an angle A (such as Figure 5As shown in FIG. 1 ), the eccentric component 25 generates a torque M1 on the training device body 10, and the sum of the torques received by the training device body 10 is equal to Mr + M1. At this time, a smaller force can be used to push the training device body 10 to rotate, thereby achieving training in the power-assisted mode.

[0035] It should be noted that when the training device body 10 rolls, the stepper motor 23 drives the eccentric component 25 to rotate synchronously, so that the eccentric component 25 maintains an unchanged angle A, thereby always achieving power training. At the same time, in the resistance mode and the normal mode, the eccentric component 25 rotates synchronously with the training device body 10.

[0036] In one embodiment, when the patient selects resistance training, the stepper motor drives the eccentric component 25 in the normal mode to rotate by an angle B (eg, Figure 6 As shown in FIG. 1 ), the eccentric component 25 generates a torque M2 on the training device body 10, and the sum of the torques received by the training device body 10 is equal to Mr-M2. At this time, a larger force is required to push the training device body 10 to rotate, thereby achieving resistance mode training.

[0037] In one embodiment, when the patient selects the normal mode training, the stepper motor drives the eccentric component 25 back to the initial position (eg Figure 7 As shown in FIG. 1 ), when the eccentric component 25 is in the initial position, the symmetry axis of the eccentric component 25 is vertically downward. At this time, the eccentric component 25 generates a torque M3 on the training device body 10, and M3=0, then the sum of the torques received by the training device body 10 is equal to Mr. At this time, the patient can push the training device body 10 to rotate, thereby achieving normal mode training.

[0038] Through the above steps, the corresponding training mode can be selected according to the patient's muscle strength level, thereby improving the training efficiency and training effect for the patient.

[0039] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
