Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an integrated electrostimulation therapy device, particularly an integrated meridian electrostimulation therapy device. Background Technology

[0002] Meridian electrostimulation therapy is a medical method that combines traditional Chinese medicine meridian theory with modern electronic technology. It uses low-frequency pulse waveforms to electrically stimulate the diseased meridians and the muscles they control. This can cause rhythmic muscle contractions, improve blood circulation, promote venous and lymphatic return, delay muscle atrophy, help compensate for the proliferation of muscle fibers, promote the recovery of nerve excitation and conduction functions, calm excited meridian nerves, and naturally relieve pain caused by muscle stiffness, thus achieving the purpose of treatment and massage.

[0003] The electrical stimulation device generates a low-frequency current that contacts the skin through connecting electrodes, allowing the current to act on the skin and meridians. Electrode patches are attached to the corresponding treatment areas on the body, connecting the positive and negative terminals of the electrical stimulation device. The pulses generated by the device pass through the patches, mimicking acupuncture and massage treatments like countless electric needles.

[0004] Currently, electrostimulation devices and meridian electrode massagers on the market are all separate from the electrodes, requiring connecting wires to connect them. The separate structure is complex, inconvenient to use, and has high production costs. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing an integrated electrostimulation therapy device, comprising a silicone protective cover, a flexible circuit board, and a conductive gel layer. It is an integrated meridian electrostimulation gel electrode therapy device, featuring a compact, easy-to-operate, and convenient structure, while also being more energy-efficient and cost-effective.

[0006] The integrated electrical stimulation therapy device is achieved through the following technical solutions: The integrated electrostimulation therapy device includes a silicone protective cover 1, a flexible circuit board 2, a conductive gel layer 3, and an insulating layer 4. The silicone protective cover 1 is mounted on the upper part of the flexible circuit board 2. The front side of the flexible circuit board 2 is equipped with a contact switch 2-1, a main control chip (CPU) 2-2, a drive module 2-3, a communication module 2-7, a power management circuit 2-8, and a button battery 2-4. The button battery 2-4 supplies power to the flexible circuit board. The back side of the flexible circuit board 2 has 2-10 electrode patches, divided into positive electrode patches 2-5 and negative electrode patches 2-6, arranged separately. The conductive gel layer 3 has a positive conductive gel layer 3-1 and a negative conductive gel layer 3-2. The positive conductive gel layer 3-1 and the negative conductive gel layer 3-2 are respectively attached to the outside of the positive electrode patches 2-5 and the negative electrode patches 2-6. An insulating area is formed between the positive conductive gel layer 3-1 and the negative conductive gel layer 3-2, and the insulating layer 4 is attached to this insulating area.

[0007] The drive module 2-3 is equipped with a low-frequency pulse current generation circuit and an H-bridge drive circuit.

[0008] The positive electrode patch 2-5 is connected to the positive terminal of the low-frequency pulse current output of the flexible circuit board. The negative electrode patch 2-6 is connected to the negative terminal of the low-frequency pulse current output of the flexible circuit board. Both the positive electrode patch 2-5 and the negative electrode patch 2-6 are made of conductive metal.

[0009] The core hardware components of the flexible circuit board 2 are as follows: 1. The main control chip CPU 2-2 adopts a domestic 32-bit ultra-low power MCU (RISC-V core), which is used for PWM generation, communication protocol processing and mode control, and outputs pulse voltage to the H-bridge circuit to control the stimulation intensity.

[0010] 2. Driver Module Low-frequency pulse current generation circuit for high voltage generation: Uses a Boost DC boost circuit to control the PWM pulse width and boost the voltage to 20-60V; The H-bridge driver circuit uses four MOSFETs, with precise timing control via the CPU. Multiple output channels of the CPU's high-precision timer are combined to control the MOSFETs of the H-bridge to turn on and off according to a strict timing sequence, generating low-frequency pulse waveforms. The pulse voltage on the sampling resistor is detected synchronously in real time, thereby calculating the actual output current. A PID algorithm is used to track load changes at high speed, ensuring a constant output current.

[0011] 3. Communication Module Bluetooth chip used: domestic BT01 (integrated 2.4GHz dual-mode), supports BLE 5.0 protocol, and enables bidirectional communication with mobile APP.

[0012] 4. The power management circuit uses the CPU's timer to work with the ADC to precisely monitor the battery voltage and control the BOOST pulse width of the MOS in real time to ensure stable power supply under different loads. The ultra-low power CPU's power management circuit ensures standby power consumption of less than 0.2uA, and with a small 32mAh battery, it can effectively standby for 2 years.

[0013] The insulation layer 4 is made of EVA foam material, which is soft and elastic, wear-resistant, pressure-resistant, waterproof, shockproof, has good anti-slip properties, is environmentally friendly, and has good insulation properties.

[0014] When using the integrated electrostimulation therapy device, the gel electrode patches are applied to the skin, meridians, and acupoints. Turning on the contact switch activates the flexible circuit board, where the positive and negative electrode areas are used to conduct micro-stimulation currents through the skin and meridians. To enhance the pain relief effect on the meridians, this therapy device uses electrode pairs—each pair consisting of one positive and one negative electrode—to provide transdermal stimulation to the skin, meridians, and acupoints through the microcurrent generated by the positive and negative electrode patches.

[0015] The integrated electrostimulation therapy device allows users to adjust the current stimulation intensity, duration, and stimulation interval mode via a mobile app.

[0016] Mobile APP control implementation method: 1. Communication Protocol Based on the Bluetooth GATT protocol, a custom UUID service is used to define characteristic values ​​such as current intensity (0x01), stimulation time (0x02), and interval mode (0x03).

[0017] 2. Control Logic Parameter adjustment: The APP slider sends hexadecimal commands to the MCU, which then parses them and dynamically adjusts the PWM duty cycle or DAC output. (Adjustments can be made to time, current stimulation magnitude, etc.).

[0018] Preset modes: Built-in "acupuncture mode" and "massage mode", etc. After selection via APP, the MCU calls the preset waveform parameters (such as 10Hz / 200μs intermittent pulse).

[0019] 3. Data Feedback The electrode impedance and remaining power are transmitted back to the APP interface in real time, and an alarm is triggered in abnormal conditions (such as poor contact).

[0020] According to the communication protocol, the APP client can establish a communication connection with the Bluetooth communication module. The digital signal output from the APP client can be transmitted to the control device through the Bluetooth communication module. Then, the control logic controls the operation of the pulse and can provide timely feedback on the treatment effect and abnormal prompts.

[0021] The integrated electrostimulation therapy device is reasonably designed, compact in structure, and easy to use. It features a silicone protective cover, flexible circuit board, conductive gel layer, and insulating layer. It is an integrated meridian electrostimulation gel electrode therapy device with a small size, convenient operation, and is more energy-efficient and cost-effective.

[0022] The integrated meridian stimulation therapy device has the following advantages: 1. Highly integrated design By integrating the pulse generator, electrode pads, and battery into a single flexible structure, it supports self-adhesive patch wear, making it far more portable than traditional separate devices.

[0023] 2. Intelligent adjustment Stimulation parameters can be dynamically optimized through AI algorithm models (such as adaptive adjustment based on impedance feedback) to avoid errors from manual parameter tuning.

[0024] 3. Multimodal therapy It integrates TENS (Transcutaneous Electrical Nerve Stimulation) and EMS (Electrical Muscle Stimulation) technologies, covering scenarios such as pain relief and muscle rehabilitation, and supports 6 preset schemes for traditional Chinese medicine meridians and acupoints.

[0025] 4. Security and Compliance It complies with the IEC 60601-2-10 standard for medical electrical equipment, has passed BF type insulation certification, and has a leakage current of <10μA, ensuring home medical-grade safety. Attached Figure Description
