Description

Technical Field

[0001] This invention relates to the field of rehabilitation exercise equipment technology, and in particular to a multifunctional exercise and rehabilitation device that prevents tipping. Background Technology

[0002] With the development of rehabilitation medicine, upright exercise equipment for patients with lower limb dysfunction has become a core component of rehabilitation institutions and home-based rehabilitation. However, existing rehabilitation exercise equipment generally suffers from several shortcomings: First, it is inconvenient for patients to operate the equipment. For patients with lower limb mobility issues, there is a lack of dedicated assistive structures, requiring staff assistance to complete the movements. This not only increases the workload of medical staff but also reduces the patient's autonomy in rehabilitation exercises. Second, the equipment lacks sufficient anti-tipping protection. During exercise, patients must rely on their upper limb strength to hold onto the handrails or grip the exercise components to maintain balance. When patients lack sufficient muscle strength and cannot maintain balance independently, they are prone to tilting, swaying, or even causing the entire equipment to tip over, leading to falls, collisions, and other safety accidents, seriously affecting the safety of rehabilitation exercises. Third, rehabilitation exercises are disconnected from effect assessment. The equipment can only provide basic limb exercise functions and cannot collect physiological signals from patients during exercise in real time, making it difficult to accurately judge the rehabilitation effect and providing data support for adjusting personalized rehabilitation plans. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional exercise and rehabilitation device that prevents tipping, thereby solving the problems mentioned in the background art.

[0014] Therefore, the present invention employs the above-mentioned anti-tipping multifunctional exercise and rehabilitation device, which has the following beneficial effects: (1) This device provides a special assistive structure for patients with lower limb mobility difficulties by setting an inclined auxiliary step on one side of the rehabilitation table and opening anti-slip texture on the surface of the step. Patients can complete the machine operation independently with the help of the step without the need for staff to help them throughout the process.

Two weight plates 91 are provided, symmetrically arranged on both sides of the bottom of the rehabilitation platform 2, increasing the weight of the bottom of the rehabilitation platform 2, lowering the center of gravity of the equipment, and preventing the rehabilitation platform 2 from tipping over.

[0031] The exercise stand 7 is also equipped with an installation unit, on which a display screen 71 is installed. The display screen 71 is electrically connected to the rehabilitation assessment system. The rehabilitation assessment system realizes the assessment of rehabilitation effect based on electromyography signal acquisition and analysis. The rehabilitation assessment system includes an electromyography signal acquisition module, a signal preprocessing module, a feature extraction module, a rehabilitation assessment module, a data storage module, and a human-computer interaction module. All modules are electrically connected.

[0032] The electromyography (EMG) signal acquisition module is used to collect EMG signals during a patient's exercise. The module includes several EMG acquisition electrodes, signal transmission lines, and a signal amplification unit. The EMG acquisition electrodes are disposable medical electrode pads, which are attached to the patient's forearm, thigh, lower back, and other muscle activity areas to collect EMG signals generated by muscle contraction. The EMG acquisition electrodes are electrically connected to the signal amplification unit via the signal transmission lines. The signal amplification unit amplifies the weak EMG signals by a factor of 1000-5000 to facilitate subsequent signal processing.

[0033] The signal preprocessing module is used to perform noise reduction and filtering on electromyography (EMG) signals. The signal preprocessing module includes a filtering unit and an analog-to-digital conversion unit. The filtering unit uses a second-order Butterworth filter to filter noise signals such as power frequency interference and equipment vibration interference in the EMG signals. The filtering frequency is 5-500Hz. The analog-to-digital conversion unit is used to convert the filtered analog EMG signals into digital signals with a conversion accuracy of 16 bits, which meets the accuracy requirements of signal processing.

[0034] The feature extraction module is used to extract the feature parameters of the processed electromyographic signal. The feature extraction module has a built-in signal processing algorithm to extract the feature parameters of the digital electromyographic signal. The feature parameters include integrated electromyographic value, root mean square value, peak value of electromyographic signal and muscle contraction frequency. The integrated electromyographic value reflects the total energy of muscle contraction, the root mean square value reflects the intensity of muscle contraction, the peak value of electromyographic signal reflects the maximum contractile capacity of muscle, and the muscle contraction frequency reflects the rhythmicity of muscle contraction.

[0035] The rehabilitation assessment module compares feature parameters with preset thresholds to achieve graded assessment of rehabilitation effectiveness. The module has a built-in rehabilitation assessment model, which is constructed based on the standard values ​​of normal human electromyography (EMG) signals and the EMG signal thresholds of patients at different rehabilitation stages. The feature parameters extracted by the feature extraction module are compared with the preset thresholds to classify the patient's rehabilitation effectiveness into four levels: Level 1 rehabilitation (extremely weak muscle contraction ability, all feature parameters are below 30% of the preset threshold), Level 2 rehabilitation (relatively weak muscle contraction ability, feature parameters are 30%-60% of the preset threshold), Level 3 rehabilitation (good muscle contraction ability, feature parameters are 60%-90% of the preset threshold), and Level 4 rehabilitation (muscle contraction ability is close to normal, feature parameters are above 90% of the preset threshold).

[0036] The data storage module is used to store raw electromyographic signal data, characteristic parameters, and evaluation results. The data storage module uses a high-capacity flash memory chip, which can store at least one year's worth of raw electromyographic signal data, characteristic parameters, and rehabilitation evaluation results. It supports local storage and export of data. The data storage module is also electrically connected to a Bluetooth / USB transmission unit to enable wireless / wired data transmission with terminal devices such as computers and mobile phones, making it convenient for medical staff to track the patient's rehabilitation process.

[0037] The human-computer interaction module uses a display screen 71 to visualize assessment results and input operation commands. The module includes a display screen 71 and operation buttons. The display screen 71 is a touch-screen LCD that can display electromyographic signal waveforms, characteristic parameters, rehabilitation assessment levels, exercise duration, and other information in real time. The operation buttons are located on the exercise base 7 and are used to input exercise parameters (such as the height, speed, and duration of upright exercises) and operation commands from the rehabilitation assessment system (such as data query, export, and parameter setting).

[0038] The above-mentioned rehabilitation assessment system adopts conventional existing technology in this field, and its principles and connection diagrams will not be elaborated here.

[0039] When using it, the steps are as follows: S1. Set the exercise parameters using the operation buttons, and set the exercise duration to 20 minutes.

[0040] S2. Assist the patient onto the rehabilitation wheelchair 1, fasten the straps 114 on the rehabilitation wheelchair 1, and secure the patient's thighs and calves. The medical staff then pushes the rehabilitation wheelchair 1 along the pusher track to the front of the exercise platform 7. At this time, the first and second curved rods 411 and 412 of the locking assembly 4 slide along the straight track 341 and oblique track 342 of the locking track 33 to the L-shaped track 343 and lock in place, achieving front positioning of the rehabilitation wheelchair 1. Figure 5 As shown.

[0041] S3. Start the second power element 53, which drives the stop block 52 to slide inward along the outer groove 51. The arc-shaped surface of the stop block 52 abuts against the rear wheel of the rehabilitation wheelchair 1. Figure 8 As shown, the rear of the rehabilitation wheelchair 1 is blocked, and the locking component 1 4 and the locking component 2 5 are locked in both directions.

[0042] S4. Rotate the rotating rod 113 to move the footboard 112 inward to avoid affecting the patient's feet on the rehabilitation part 23 for rehabilitation. At this time, start the power element 109. The output end of the power element 109 slowly extends, driving the connecting base plate 103 and the back plate 105 to rotate synchronously, assisting the patient to gradually transition from a sitting position to an upright position. The patient holds the exercise armrest 86 with their hands, steps on the rehabilitation part 23 with their feet, and fastens the buttock support strap 82 around the patient's buttocks with buckle two, and fastens the back support strap 81 around the patient's waist and back with buckle one, completing the support and fixation of the patient. Loosen the straps 114 of the rehabilitation wheelchair 1.

[0043] S5. Place the electromyography (EMG) electrodes on the patient's forearm flexors, quadriceps femoris, erector spinae muscles in the lower back, and other muscle activity areas, ensuring that the electrode pads are in close contact with the skin without loosening or falling off.

[0044] S6. During the exercise, the electromyography signal acquisition module collects the patient's electromyography signals in real time. After noise reduction and analog-to-digital conversion by the signal preprocessing module, the feature extraction module extracts feature parameters such as integral electromyography value and root mean square value. The rehabilitation assessment module compares the feature parameters with preset thresholds to achieve graded assessment of rehabilitation effect. The assessment results, electromyography signal waveforms and other information are displayed in real time on the display screen 71.

[0045] S7. After the exercise duration reaches the preset value, the power element 109 slowly retracts, driving the connecting base plate 103 and back plate 105 back to the sitting position. The back support strap 81 and hip support strap 82 are then released in sequence, and the patient is helped onto the rehabilitation wheelchair 1 and the straps 114 are fastened. The power element 253 is then activated, causing the stop block 52 to slide downwards, unlocking the locking component 25. The medical staff steps on the pressing plate 416, and the traction line 415 pulls the first link 44 and the second link 45 to slide towards each other, simultaneously pulling the rehabilitation wheelchair 1. The curved rod 1 411 and the curved rod 2 412 slide out from the L-shaped channel 343, unlocking the locking component 14, and pushing the rehabilitation wheelchair 1 along the push track to complete this exercise.

[0046] Medical staff can query and export the electromyographic signal data and rehabilitation assessment results of this exercise through the display screen 71 or Bluetooth / USB transmission unit, record the patient's rehabilitation status, and provide a basis for adjusting the subsequent rehabilitation plan.

[0047] Therefore, the present invention adopts the above-mentioned anti-tipping multifunctional exercise and rehabilitation device. Through the multi-level locking structure of locking component one and locking component two, the rehabilitation wheelchair and rehabilitation platform are accurately positioned. Locking component one can slide along the locking channel and lock in position. Locking component two uses a stop block to achieve a hard block at the rear of the rehabilitation wheelchair. The two-way locking prevents the wheelchair from shifting forward or backward during exercise. Combined with the anti-tipping component, it achieves anti-tipping protection from the overall device and local parts, greatly improving the safety of rehabilitation exercise.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
