Technical Field

[0001] This invention relates to the field of somatosensory intervention devices, specifically a closed-loop somatosensory intervention device for restless legs syndrome. Background Technology

[0002] Restless legs syndrome (RLS) is a common neurosensory-motor disorder characterized by an inexplicable and abnormal discomfort in the lower limbs during rest or sleep at night, accompanied by a strong and irresistible urge to move the legs. While moving the legs can temporarily relieve symptoms, it severely interferes with falling asleep and maintaining sleep, leading to chronic sleep deprivation, daytime fatigue, decreased quality of life, and mental health problems.

[0003] Most devices offer only a single modality, such as vibrational stimulation, and the stimulation parameters—intensity, frequency, and mode—are fixed or have a limited adjustable range, making it impossible to personalize and adaptively adjust to individual differences and dynamic changes in symptoms. Different patients, or even the same patient at different times, may have different symptom triggers and effective relief methods. Fixed modes are unlikely to achieve optimal intervention results and can only treat a single area of ​​the patient. Summary of the Invention

[0018] This invention provides a closed-loop somatosensory intervention device for restless legs syndrome, such as... Figure 1-5 As shown, the device includes a main control unit housing 101, which extends outwards from the top to both sides. A main controller 122 is fixedly mounted on one side of the top of the main control unit housing 101. A disc-shaped vibration motor housing 121 is fixedly mounted on the back of the main control unit housing 101. A vortex-shaped massage groove 120 is provided inside the vibration motor housing 121. Two semiconductor temperature control chips 119 are fixedly mounted on the back of the main control unit housing 101 and on both sides of the vibration motor housing 121. The semiconductor temperature control chips 119 on both sides are symmetrically arranged. Both ends of the main control unit housing 101 have through-holes 102 for wearing. The through-holes 102 are symmetrically arranged. Adjustable straps 103 are inserted into the through-holes 102. Connecting straps 117 are respectively installed and connected to the adjustable straps 103 on both sides. A strap tension adjuster 113 is installed between the connecting straps 117 on both sides. The strap tension adjuster 113 adjusts the tightness of the connecting straps 117.

[0019] It should be further explained that a vortex-shaped enclosed plate is installed inside the massage groove 120, and the semiconductor temperature control chip 119 plays a role in temperature regulation. An electromyography sensor and an inertial measurement unit are provided inside the connecting strap 117.

[0020] Furthermore, a lifting execution module 112 capable of lifting and moving is provided below the main control unit housing 101, and two telescopic brackets 109 are fixedly provided at the bottom of the main control unit housing 101. The telescopic brackets 109 on both sides are symmetrically arranged, and the lifting execution module 112 is connected to the telescopic brackets 109 for lifting and moving.

[0021] Furthermore, a motor drive module 111 is installed at one end of the lifting execution module 112. The motor drive module 111 is used to control the height adjustment between the lifting execution module 112 and the telescopic bracket 109.

[0022] Furthermore, a signal transmission cable 110 of sufficient length is electrically connected between the motor drive module 111 and the main controller 122. A control knob 107 is installed on one side of the main controller 122. The control knob 107 is used to transmit signals through the signal transmission cable 110 and control the motor drive module 111 to start, thereby achieving the effect of adjusting the lifting execution module 112 and the height.

[0023] Furthermore, a microcurrent stimulation electrode array 118 is installed on the back of the lifting execution module 112, and a haptic feedback start / stop button 108 is installed on one side of the main controller 122. The haptic feedback start / stop button 108 is used to control the start / stop effect of the microcurrent stimulation electrode array 118.

[0024] Furthermore, the main control unit housing 101 has two outward-facing temperature control unit interface slots 104 on one side, the positions of the temperature control unit interface slots 104 correspond to the positions of the semiconductor temperature control chip 119, and the positions of the temperature control unit interface slots 104 are symmetrically arranged.

[0025] Furthermore, two temperature control panels 106 are installed on one side of the main control unit housing 101 and on both sides of the main controller 122. One end of the temperature control panel 106 is electrically connected to the temperature control unit power line 105. The temperature control unit power line 105 passes through the temperature control unit interface slot 104 and is electrically connected to the semiconductor temperature control chip 119.

[0026] It should be further explained that the temperature control panel 106 is equipped with a human-machine interface, which can control and display the temperature, and adjust the temperature of the semiconductor temperature control chip 119 through the power connection of the temperature control unit power line 105.

[0027] Furthermore, a knob mounting bracket 116 is fixedly provided on the top of the main control unit housing 101, a vibration adjustment knob 115 is rotatably provided inside the knob mounting bracket 116, and a knob encoder 114 is fixedly provided at one end of the knob mounting bracket 116.

[0028] It should be further explained that the knob encoder 114 is connected to the vibration motor housing 121 for control. The operator can control the vibration massage effect of the vibration motor housing 121 by rotating the vibration adjustment knob 115 and through the knob encoder 114.

[0029] When using this solution: S1. The user first attaches the main control unit housing 101 and the modules integrated thereon to the back of the calf or the area with obvious symptoms. Then, the user passes the two adjustable straps 103 through the wearing holes 102 on both sides and wraps them around the calf. The user uses the connecting straps 117 and the strap tension adjuster 113 to comfortably and securely bind the device. The user then adjusts the tightness to ensure that the microcurrent stimulation electrode array 118, semiconductor temperature control plate 119 and vibration motor housing 121 on the back maintain good contact with the skin. This is the basis for ensuring signal acquisition and intervention effects. After wearing the device, the user can preset the preferred heat therapy temperature through the human-computer interaction interface on the temperature control panel 106 and select the initial vibration mode and intensity level by rotating the vibration adjustment knob 115. S2. After the device is powered on, the closed-loop system starts to work. The physiological signal acquisition module integrated inside the connecting strap 117 starts to continuously and in real time monitor the electromyographic activity and movement status of the user's calf. The acquired raw signals are transmitted to the main controller 122 for processing. The symptom recognition model pre-stored in the main controller 122 or generated by the learning algorithm performs feature analysis on the input signal. When the analysis results exceed the preset asymptomatic resting threshold, the system determines that the user may have entered the pre-symptom or attack phase. S3. Once the main controller 122 identifies potential symptoms, it will automatically make a decision and trigger one or more combined intervention modes based on preset algorithms or historical valid data. This process does not require manual operation by the user. S3.1 Vibration Intervention: The main controller 122 drives the eccentric rotor motor inside the vibration motor housing 121 to work, generating tactile vibrations of specific patterns and intensities; The vibration mode can be overridden or fine-tuned by receiving the manual adjustment signal from the vibration adjustment knob 115 via the knob encoder 114.

[0030] S3.2, Thermotherapy Intervention: The main controller 122 sends a command to the designated semiconductor temperature control chip 119 through the power line 105 of the temperature control unit, so that it starts to heat up to the set temperature and provides gentle heat to the local skin and deep tissues.

[0031] S3.3 Microcurrent stimulation intervention: The main controller 122 starts the microcurrent stimulation electrode array 118 through the circuit of the somatosensory feedback start / stop button 108, so that it outputs a safe, low-frequency microcurrent to gently stimulate the subcutaneous nerves. The above interventions can be performed individually or in combination to achieve the best sensory distraction and neuromodulation effects; S4. During and after the intervention, the physiological signal acquisition module continues to monitor the user's electromyography and motor signals and feeds the data back to the main controller 122 in real time. The algorithm within the main controller 122 will evaluate the intervention effect, such as comparing whether the electromyographic activity level before and after the intervention has decreased significantly and whether involuntary movements have stopped. S4.1 If the feedback signal indicates that the symptoms have been effectively relieved, the main controller 122 can instruct the intervention module to gradually reduce the intensity or switch to maintenance mode in order to save power and avoid overstimulation. S4.2 If the feedback signal shows that the symptoms have not been relieved or have even worsened, the main controller 122 will start the adaptive adjustment program and command the motor drive module 111 to drive the lifting execution module 112 to make a slight downward adjustment along the telescopic bracket 109 through the instructions received by the control knob 107 or autonomous decision, so as to increase the contact pressure between the electrodes and the temperature control pad and the skin. At the same time, it automatically increases the vibration intensity, microcurrent intensity, or thermotherapy temperature until a positive physiological feedback signal is detected.

[0032] S5. Throughout the process, users can view and adjust the heat therapy temperature at any time via the temperature control panel 106; Switch the massage rhythm by rotating the vibration adjustment knob 115; All stimulation can be paused with a single click using the haptic feedback start / stop button 108; In addition, the control knob 107 allows users to manually adjust the height of the lifting actuator module 112 to change the pressure sensation or the degree of stimulation, giving the device flexible operability.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
