Description

Technical Field

[0001] The present invention relates to the technical field of electro-acupuncture apparatuses, and particularly to a wearable electro-acupuncture apparatus. Background Art

[0002] An electro-acupuncture apparatus, also known as an electro-acupuncture device or electro-acupuncture machine, is an electrical energy output device specifically designed for electro-acupuncture therapy and acupuncture anesthesia. During the treatment process, when the acupuncture needle is inserted into a specific acupoint and a needle sensation is generated, the output circuit is connected to the needle, and the electro-acupuncture apparatus immediately releases an electric current with a specific waveform and frequency to simulate and replace traditional manual stimulation. Through the action of the meridians and acupoints, the electro-acupuncture apparatus can effectively treat diseases or relieve pain, and at the same time has the dual physiological effects of acupuncture and electrical stimulation. In addition, the electro-acupuncture apparatus has unique value in the adjuvant treatment of tumors with drugs, and can significantly prevent and treat side effects such as peripheral neuropathy and stomatitis. Its application can relieve the pain of patients, improve the treatment effect, and provide more comprehensive and effective medical services for patients.

[0003] The electro-acupuncture apparatuses currently on the market are mainly divided into two categories: traditional pulsed electro-acupuncture apparatuses and digital electro-acupuncture apparatuses. Traditional pulsed electro-acupuncture apparatuses are relatively large in size. For example, the size of the Xianhe brand HJ-200 electro-acupuncture apparatus is 230mm×160mm×60mm, and the size of the Yingdi brand KWD-808-I electro-acupuncture apparatus is 220mm×172mm×75mm. In addition, this type of device uses a wired connection method to connect the electro-acupuncture needles to the main unit, resulting in inconvenient operation for medical staff. Parameter adjustment usually relies on the knobs on the device and it is difficult to achieve precise settings. Digital electro-acupuncture apparatuses are mainly controlled by a single-chip microcomputer, and parameter adjustment is more precise, but the fixing method is relatively single, usually using acupuncture or sticking for fixation.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention provides a wearable electro-acupuncture instrument, which has the following beneficial effects:

[0018] 1. The wearable electro-acupuncture instrument adopts a compact integrated design and is equipped with a 110mAh polymer lithium battery, ensuring long-term battery life. The circuit board and the power supply system are highly integrated, reducing the use of external connection wires, making the wearing more convenient and comfortable. At the same time, the device supports Bluetooth data transmission, eliminating the need for additional connection wires or external controllers, further enhancing portability. Compared with traditional electro-acupuncture treatment devices, this device can be worn on the body at any time for treatment, especially suitable for people who work for a long time, athletes or patients with chronic diseases, enabling them to flexibly use electro-acupuncture therapy in daily life.

[0019] 2. This wearable electro-acupuncture device adopts high-precision current control and adjusts the current magnitude through PWM (Pulse Width Modulation) technology, making the stimulation current stable and controllable. The device supports the receptor resistance estimation function, detects the resistance of the patient's skin or muscle before treatment, and adjusts the output parameters accordingly to ensure a personalized stimulation plan. This precise control method not only improves the effectiveness of electro-acupuncture therapy but also reduces the stimulation discomfort caused by excessive or insufficient current, making the treatment safer and more efficient, especially suitable for users who require long-term low-intensity electro-acupuncture stimulation, such as those for nerve rehabilitation or chronic pain relief.

[0020] 3. This wearable electro-acupuncture device uses a Nordic nRF52840 MCU and supports Bluetooth 5.0 communication, enabling remote control through a mobile terminal (such as a mobile phone or tablet). Users can set electro-stimulation parameters, including pulse intensity, pulse period, etc., on the exclusive interactive interface and can remotely adjust or stop the treatment at any time. This remote control function not only improves the operation convenience but also enables doctors or rehabilitation experts to remotely monitor the patient's treatment situation, provide personalized adjustment suggestions, reduces the need for patients to frequently visit medical institutions, and improves the flexibility and adaptability of use.

[0021] 4. This wearable electro-acupuncture device has a heating element built into the strap mechanism and is equipped with a temperature sensor to continuously monitor and adjust the temperature, ensuring that the temperature of the skin contact area is always maintained within a comfortable range. The combination of warm stimulation and electro-acupuncture therapy can enhance local blood circulation, improve tissue metabolism, and accelerate the rehabilitation process. Compared with traditional electro-acupuncture therapy, this device provides an additional heat therapy effect, enabling users to obtain a more comfortable experience during treatment, while avoiding discomfort caused by a low-temperature environment or long-term wearing, making the device more suitable for patients in cold climates or those with poor blood circulation.

[0022] 5. This wearable electro-acupuncture device is equipped with a magnetic needle cap and a protection mechanism, which can effectively prevent accidental exposure or accidental touch of the electro-acupuncture needles and cause injury. The needle cap is firmly fixed by magnetic attraction and combined with a locking structure to prevent detachment due to external forces. When the user does not use the device, the electro-acupuncture needles can be protected by the needle cap to prevent dust or bacterial contamination, while reducing the risk of stabbing caused by accidental operation. This safety design improves the convenience of daily use of the device and ensures the safety of users when carrying or storing the device, especially suitable for elderly users or sports rehabilitation scenarios.

When the upper cover 1 is pushed into the inner wall of the device housing 4, at this time, the upper magnet block 24 in the upper cover 1 moves to the bottom of the upper magnet block 27, and the upper magnet block 27 is magnetically attracted by the upper magnet block 24 and moves downward, so that the upper magnet block 27 clamps the upper cover 1, locking the upper cover 1. When it is necessary to open the upper cover 1, press the upper pressing key 22. The upper pressing key 22 drives the first connecting member 23 and the upper magnet block 24 to move downward, so that the upper magnet block 24 no longer magnetically attracts the upper magnet block 27.

[0048] In summary, the steps for using the wearable electro-acupuncture device are as follows:

[0049] 1. Prepare the device: Ensure that the power supply battery 9 is charged or connected to the power supply, and the computer has been successfully connected to the control circuit core board 10 via Bluetooth to ensure sufficient battery power.

[0050] 2. Estimate the receptor resistance: Pierce the electro-acupuncture needles 7 of the wearable micro electro-acupuncture device into the receptor, and the binding mechanism 8 can be used for auxiliary fixation.

[0051] 3. Set the relevant parameters: After the resistance is estimated, drag the current control slider to set the current. The pulse intensity will automatically change with different current settings, and fill in the values of the pulse period, pulse width, and pulse number.

[0052] 4. Conduct electrical stimulation: Click the yellow lightning button of the data remote transmission start button, and the electroacupuncture instrument can transmit the relevant parameters of the input current to the receptor through the electroacupuncture needle 7.

[0053] 5. Stop electrical stimulation: Click the red rectangular button marked with "Stop" of the stop button, close the udp_ble_node.exe file and the terminal interface program of the wearable micro-electroacupuncture instrument, remove the wearable micro-electroacupuncture instrument from the receptor, and cover the electroacupuncture needle 7 with the needle cap 6.

[0054] Combined with Figure 1 - Figure 4 , the working principle of the electroacupuncture instrument is as follows: Run the Bluetooth-to-UDP communication program to establish communication between the terminal and the electroacupuncture instrument. Then, first estimate the receptor resistance R3 through two electroacupuncture needles 7. The estimation is controlled by the analog-to-digital converter of the chip. The function of the analog-to-digital converter combines the technology of adjusting the pulse width to control the analog signal and is realized in cooperation with the circuit. Specifically, the P0.03 (PWM0) pin of the core board emits a short pulse with a duty cycle of 100%. Before the pulse ends, measure the voltage of the P0.02 ADC0 pin. According to the polynomial fitting method, the fitting coefficient is obtained by fitting the measured resistance values and the corresponding pin voltage return values to estimate the resistance value. Then, set other parameters and execute. The corresponding equivalent voltage is sent to the electroacupuncture needle 7 through the P0.03 (PWM0) pin of the core board and is converted into the corresponding current. Here, the equivalent voltage is also realized through the PWM function, that is, by adjusting the duty cycle.

[0055] When not in use, dock the needle cap 6 with the fixed round block 59 magnetically. At this time, the needle cap 6 drives the cylindrical disk 55 and the positioning block 58 to move upward, so that the inclined surface of the positioning block 58 abuts against the end surface of the hollow ring 56, causing the positioning block 58 to compress the spring four 57. Then, under the action of the spring four 57, the positioning block 58 is clamped with the hollow ring 56 to realize the stable connection of the cap, avoid the exposure of the electroacupuncture needle 7, and improve safety. When it is necessary to release the fixation, push the arrow button 53. The arrow button 53 drives the connecting block 52, and the connecting block 52 drives the positioning block 58 to retract into the cylindrical disk 55 through the pull rope 54, so that the cylindrical disk 55 is no longer clamped with the fixed round block 59. A dual mechanism (magnetic attraction + mechanical locking) is adopted to ensure that the needle cap 6 will not fall off due to slight vibration or collision. Only by pressing the arrow button 53 can it be actively unlocked to prevent potential safety hazards caused by misoperation. Avoid misoperation during the carrying process.

[0056] Push the upper cover 1 onto the inner wall of the device housing 4. At this time, the first upper magnet block 24 in the upper cover 1 moves to the bottom of the second upper magnet block 27. The second upper magnet block 27 is magnetically attracted by the first upper magnet block 24 and moves downward, causing the second upper magnet block 27 to latch onto the upper cover 1, locking the upper cover 1. When it is necessary to open the upper cover 1, press the upper push button 22. The upper push button 22 drives the first connecting member 23 and the first upper magnet block 24 to move downward, so that the first upper magnet block 24 no longer magnetically attracts the second upper magnet block 27. The second upper magnet block 27 moves upward under the action of the second spring 26, so that the second upper magnet block 27 no longer latches onto the upper cover 1, achieving the effect of releasing the latching. The design of magnetic attraction plus mechanical pressing unlocking makes the operation more convenient, avoids the use of screws or other complex fixing structures, improves the usability and maintenance efficiency of the device, and avoids accidental operation during the carrying process.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
