Description

Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation equipment, in particular to a vestibular utricle rehabilitation training device. Background Art

[0002] Vestibular rehabilitation utilizes the plasticity and compensatory functions of the cerebral cortex, cerebellum, and vestibular nuclei to promote gradual vestibular compensation through a series of exercises involving the eyes, neck, head, and trunk. This approach improves vertigo and dizziness in patients with impaired vestibular function, enhances visual clarity, improves balance, and prevents falls. The prevalence of vestibular system disorders increases with age, particularly in those over 60 years old. Consequently, the demand for vestibular rehabilitation is growing.

[0003] The vestibular system is an important component of the human body's ability to maintain balance and spatial orientation. The utricle is responsible for sensing linear acceleration and plays a vital role in maintaining balance, spatial orientation, and controlling eye movements. By sensing changes in the head's linear acceleration in three-dimensional space, it works in conjunction with the semicircular canals to ensure that the body can adapt to various motion states and prevent and alleviate symptoms such as motion sickness. When the utricle is damaged or dysfunctional, it can cause symptoms such as dizziness and balance disorders, seriously affecting the patient's quality of life. Traditional rehabilitation methods often rely on medication and physical therapy, but they are limited in terms of targeting, personalization, and rehabilitation efficiency. Utility Model Content

The upper surface of the slider 7 is fixed with a horizontal mounting base 13, and the upper surface of the horizontal mounting base 13 is fixed with two vertical support plates 14 set at intervals. A seat 15 is installed on the top of the two vertical support plates 14. The front end of the horizontal mounting base 13 is used as a place for human feet. A protective component 16 for protecting the human body is installed on the seat 15. The protective component 16 includes an armrest protection belt 17, a torso protection fixing belt 18 and an abdominal protection safety belt 19. The armrests on the left and right sides of the seat 15 are fixed with armrest protection belts 17, and an emergency stop button 20 is provided on the armrest. A torso protection fixing belt 18 is provided on the inner side of the backrest of the seat 15, and an abdominal protection safety belt 19 is provided at the bottom of the inner side of the backrest of the seat 15. A sensor component 21 is provided on the slider 7, and the sensor component 21 includes a displacement sensor 22, a speed sensor 23 and an acceleration sensor 24. The displacement sensor 22, the speed sensor 23 and the acceleration sensor 24 are all electrically connected to the controller 25. The drive component is electrically connected to the controller 25 so that the controller 25 controls the start and pause of the drive component to drive the seat 15 to move forward and backward.

[0014] Side guardrails 26 are fixed on both sides between the front guard frame 1 and the rear guard frame 2 , and the side guardrails 26 are located on the left and right sides of the seat 15 .

[0015] A power supply 27 is installed on the rear protective frame 2 , and the power supply 27 is used to supply power to the displacement sensor 22 , the velocity sensor 23 , the acceleration sensor 24 , the linear motor 12 and the controller 25 .

[0016] The controller 25 is a host computer including a single-chip microcomputer, which adopts an STM32 series single-chip microcomputer. According to the function of each port pin of the STM32 series single-chip microcomputer, it is a conventional setting for technicians in this field to determine which specific port pin of the STM32 series single-chip microcomputer is electrically connected to each electronic device (displacement sensor 22, velocity sensor 23, acceleration sensor 24, linear motor 12). It is a conventional setting for technicians in this field and is existing technology.

[0017] The displacement sensor 22, velocity sensor 23, acceleration sensor 24, drive motor 12 and controller 25 selected in this embodiment according to actual needs are all existing commercial products. No improvement has been made to their structures and they are all existing structures. Therefore, the specific structures, circuit designs and working principles of the displacement sensor 22, velocity sensor 23, acceleration sensor 24, drive motor 12 and controller 25 are all publicly available existing technologies. The specification only uses these electronic devices to achieve certain functions. There is no need to describe in detail the specific structures, circuit designs and working principles of these existing electronic devices, and the entire solution is also clear.

[0018] The process of using the vestibular utricle rehabilitation training device is as follows: first, the patient sits on the seat 15 of this device, and the medical staff fastens the armrest protection belt 17, the torso protection fixing belt 18, and the abdominal protection safety belt 19 for the patient. Then, the medical staff uses the controller 25 to set the movement speed and / or acceleration, and the drive component starts running according to the setting.

[0019] The controller 25 controls the start-up of the drive component based on the set translation speed, and the screw rod 28 drives the slider 7 to move horizontally on the guide rail 4, so that the target rehabilitation trainee on the seat 15 moves horizontally accordingly. During the movement, the current displacement detected in real time by the displacement sensor 22 and the current translation speed detected in real time by the speed sensor 23 are received, and the speed of the drive component is adjusted based on the current translation speed so that the detected current translation speed is equal to the target translation speed and maintained. When the current displacement reaches the set displacement, the control screw rod 28 drives the slider 7 to move horizontally in the opposite direction on the guide rail 4, so that the target rehabilitation trainee on the seat 15 moves horizontally in the opposite direction accordingly.

[0020] The controller 25 controls the start-up of the drive component based on the set translation acceleration, and the screw rod 28 drives the slider 7 to move horizontally with acceleration on the guide rail 4, so that the target rehabilitation trainee on the seat 15 moves horizontally with acceleration. During the movement, the current displacement detected in real time by the displacement sensor 22 and the current translation acceleration detected in real time by the acceleration sensor 24 are received, and the acceleration of the screw rod 28 is adjusted based on the current translation acceleration so that the detected current translation acceleration is equal to the target translation acceleration and maintained. When the current displacement reaches the set displacement, the control screw rod 28 drives the slider 7 to move horizontally with acceleration in the reverse direction on the guide rail 4, so that the target rehabilitation trainee on the seat 15 moves horizontally with acceleration in the reverse direction.

[0021] In this embodiment, after activation, the drive assembly drives seat 15 to move horizontally. During this movement, controller 25 collects signals detected by sensor assembly 21, dynamically adjusting the speed and acceleration of the movement to simulate various linear motion scenarios encountered in daily life. This controllable speed and acceleration directly stimulates the vestibular utricle, promoting the restoration and enhancement of its neurons' ability to process linear motion information.

[0022] During operation, the device avoids accidental injuries caused by the seat 15 detaching from the guide rail 4 during use through the front limit switch 5, the rear limit switch 6 and the anti-overshoot baffle 11, thereby ensuring the safety of the patient.

[0023] This embodiment enables the rehabilitation trainee to move horizontally forward and backward (with the rehabilitation trainee as a reference point). Example 2

[0024] On the basis of Example 1, Figure 2 As shown, the vestibular utricle rehabilitation training device of this embodiment also includes: a bearing is embedded in the slider 7, the inner shaft of the bearing is connected to a rotating shaft, a driven gear 29 is fixedly mounted on the rotating shaft, a horizontal mounting base 13 is fixed to the surface of the driven gear 20, a motor 30 is fixed on the slider 7, a driving gear 31 is fixed on the output shaft of the motor 30, and the driving gear 31 is meshed with the driven gear 20.

[0025] The controller 25 is also used to control the rotation of the motor 30, which drives the driving gear 31 to rotate, and the driven gear 29 and the rotating shaft to rotate accordingly, thereby driving the seat 15 to rotate the rehabilitation trainee in the seat 15 to any angle. For example, the motor 30 drives the seat 15 to rotate 90 degrees, allowing the rehabilitation trainee to move horizontally left and right (with the rehabilitation trainee as the reference point).
