Description

Technical Field

[0001] This invention relates to the field of electrical stimulation and regulation of the nervous system, specifically to an intelligent ear vagus nerve stimulation weight loss device. Background Technology

[0002] In recent years, obesity has become a global health problem. Traditional weight loss methods, such as drug intervention and weight loss surgery, have problems such as significant side effects, high costs, and limited applicability. Non-invasive neuromodulation techniques, especially transcutaneous vagus nerve stimulation (taVNS), have gradually become a research hotspot due to their mechanisms of action, such as regulating the dynamic secretion of appetite-related hormones (e.g., Ghrelin and Leptin) by stimulating branches of the vagus nerve in the ear, and promoting the browning of white adipose tissue. However, existing taVNS devices still have some limitations.

[0003] First, traditional devices mostly use ear clips or adhesive electrodes, which can easily cause ear swelling and pain when worn for a long time, and are prone to falling off during exercise, affecting the treatment effect. In addition, there are great individual differences in acupoints in the concha (such as "stomach" and "endocrine"). Existing devices rely on fixed electrode positions and cannot adapt to different ear shapes, resulting in inconsistent stimulation effects. At the same time, medical-grade taVNS devices are usually bulky and require external power or frequent charging, which limits their use in daily life.

[0004] Secondly, most devices only provide electrical stimulation, resulting in a poor user experience and making it difficult for users to adhere to them in the long term. In addition, traditional methods mostly fail to dynamically optimize stimulation parameters by combining user physiological data (such as body fat percentage and meal times), making it difficult to objectively assess the therapeutic effect.

[0005] Therefore, there is an urgent need for a new type of taVNS weight reduction device that can provide an effective solution to the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent ear vagus nerve stimulation weight loss device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A smart ear vagus nerve stimulation weight loss device, characterized by comprising a pair of main units: each main unit integrates a microcurrent generator, a bioimpedance sensor, a microcontroller chip, a power module, and a wireless or Bluetooth transmission module; each main unit includes a V-shaped malleable gel stimulation head that conforms to the contour of the auricle, and the bioimpedance sensor monitors the degree of conformation between the malleable gel stimulation head and the auricle contour in real time; the microcurrent generator stimulates acupoints related to the secretion of ghrelin and leptin in the auricle region through the malleable gel stimulation head; the power module includes a charging compartment and a built-in rechargeable battery, the built-in rechargeable battery being housed inside the main unit; the charging compartment works with the main unit to charge the built-in rechargeable battery; the main unit transmits data to a mobile APP via the wireless or Bluetooth transmission module.

[0009] Furthermore, the main unit is an ear clip structure, and also includes a suspension bridge and a rear cavity, with the rear cavity connected to the plastic gel stimulation head via the suspension bridge.

[0010] Furthermore, the host unit also has a built-in music player.

[0011] Furthermore, it also includes a detachable rear hanger, which is detachably connected to the main unit. The detachable rear hanger includes an arc-shaped hoop with elbows at both ends. Each elbow on both sides is equipped with a connector. The outer wall of the main unit is provided with a plug interface, which is engaged with the connector.

[0012] Furthermore, the detachable rear mount has a built-in auxiliary battery, and the plug interface is electrically connected to the plug connector. The auxiliary battery and the built-in rechargeable battery together power the main unit.

[0013] Furthermore, a flexible silicone layer is provided on the inner surface of the arc-shaped band, and when worn, the flexible silicone layer fits tightly against the area below the occipital bone.

[0014] Furthermore, decorative flowers are provided on the outer side of the elbow.

[0015] Furthermore, the mobile app dynamically adjusts acupoint stimulation parameters using AI algorithms combined with the user's personal parameters.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention employs a synergistic design of a V-shaped malleable gel stimulation head and a bioimpedance sensor, combined with an AI algorithm to dynamically adjust stimulation parameters. It can precisely target key acupoints in the concha region, including those related to the "stomach" and "endocrine" systems. Furthermore, by stimulating the vagus nerve region, it inhibits Ghrelin secretion and increases leptin levels, promoting the browning of white fat, enhancing fat burning, and achieving appetite regulation and metabolic enhancement.

[0018] 2. The ear clip main unit and detachable back hook design of this invention form a dual fixation system of "ear + back of head" through the combination of suspension mechanical structure and arc-shaped hoop, which can maintain stable wearing in scenarios such as sports and sleep. At the same time, the flexible silicone layer and decorative flower design take into account both comfort and aesthetics.

[0019] 3. This invention integrates electrical stimulation with personalized Bluetooth five-tone therapy music playback, and can display the treatment effect in real time and dynamically adjust the plan, thereby improving user compliance and long-term use effect.

[0020] 4. This invention adopts a dual power supply design with a built-in battery in the main unit and a rear-mounted auxiliary battery, which can be used in conjunction with a wireless charging case to meet the power needs of different usage scenarios and maintain the portability and ease of use of the device.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 4-5A smart ear vagus nerve stimulation weight loss device is characterized by comprising a pair of main unit units 2: each main unit 2 has a built-in microcurrent generator, a bioimpedance sensor, a microcontroller chip, a power module, and a wireless or Bluetooth transmission module; the main unit 2 includes a V-shaped malleable gel stimulation head 201, which conforms to the contour of the auricle, and the bioimpedance sensor monitors the degree of conformation between the malleable gel stimulation head 201 and the auricle contour in real time; the microcurrent generator stimulates acupoints related to the secretion of ghrelin and leptin in the auricle area through the malleable gel stimulation head 201; the power module includes a charging compartment and a built-in rechargeable battery, which is housed inside the main unit 2; the charging compartment works with the main unit 2 to charge the built-in rechargeable battery; the main unit 2 transmits data to a mobile APP via the wireless or Bluetooth transmission module.

[0029] The main unit 2 is an ear clip structure and also includes a suspension bridge 202 and a rear cavity 203. The rear cavity 203 is connected to the plastic gel stimulation head 201 through the suspension bridge 202.

[0030] The main unit 2 also has a built-in music player.

[0031] The mobile app uses AI algorithms combined with the user's personal parameters to dynamically adjust the acupoint stimulation parameters.

[0032] Working principle of this embodiment:

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, the host unit 2 integrates a microcurrent generator, a bioimpedance sensor, a microcontroller chip, a Bluetooth 5.0 module, and a music player. The malleable gel stimulation head 201 features a V-shaped design that conforms to the contour of the auricular region. Through the conductive gel, it precisely stimulates acupoints related to appetite regulation (such as "stomach" and "endocrine") or the auricular vagus nerve area, thus achieving a weight-loss effect. In particular, transcutaneous auricular vagus nerve stimulation (taVNS) regulates appetite-related hormones (such as ghrelin and leptin) and promotes the browning of white adipose tissue by stimulating branches of the vagus nerve in the ear, thereby controlling appetite and improving fat metabolism to achieve weight loss. The bioimpedance sensor monitors the contact impedance between the gel and the skin in real time, and the microcontroller chip provides feedback on the fit to the mobile app, ensuring accurate stimulation positioning. The microcurrent generator uses AI algorithms to dynamically adjust stimulation parameters (frequency and intensity) to inhibit ghrelin secretion and increase leptin levels. A built-in rechargeable battery supports wireless charging, enhancing portability.

[0034] In this embodiment, the rear cavity 203, the suspension bridge 202, and the malleable gel stimulation head 201 form the same ear clip wearing structure as the ear clip earphone, which is firmly fixed to the outer ear when worn.

[0035] In this embodiment, the mobile APP can identify key acupoints ("stomach" and "endocrine") in the concha region through AI algorithm (CNN auricular acupoint positioning model) and dynamically adjust stimulation parameters (based on user body fat percentage, eating time, and other data).

[0036] In this embodiment, the Bluetooth 5.0 module supports personalized Bluetooth five-tone therapy music playback function and synchronous operation with electrical stimulation, improving user compliance.

[0037] The specific working steps of this embodiment are as follows: the user scans the code to enter the App → AI identifies ear acupoints → the gel is applied to the concha area → the user selects the weight reduction mode (music / intensity adjustable) → real-time impedance monitoring and optimization of the stimulation program.

[0038] Example 2: Please refer to Figures 1-3 A smart ear vagus nerve stimulation weight loss device, which differs from Embodiment 1 in that it also includes a detachable back hanger 1, which is detachably connected to the main unit 2. The detachable back hanger 1 includes an arc-shaped hoop 101, with elbows 102 at both ends of the arc-shaped hoop 101. Each elbow 102 on both sides is provided with a connector 103. An interface 204 is provided on the outer wall of the main unit 2, and the interface 204 is plugged into the connector 103.

[0039] The detachable rear mount 1 has a built-in auxiliary battery. The plug interface 204 is electrically connected to the plug connector 103. The auxiliary battery and the built-in rechargeable battery together power the main unit 2.

[0040] The inner surface of the arc-shaped hoop 101 is provided with a flexible silicone layer, which fits tightly against the underside of the occipital bone when worn.

[0041] Working principle of this embodiment:

[0042] like Figure 1-3 As shown, the arc-shaped band 101 can be made of lightweight elastic material, with a flexible silicone layer on the inside, fitting snugly under the user's occipital bone when worn, avoiding slippage or pressure discomfort. The connector 103 at the end of the elbow 102 plugs into the connector 204 of the main unit 2 to achieve mechanical fixation and electrical connection. The auxiliary battery is integrated in the rear hanger, and is connected in parallel with the built-in rechargeable battery of the main unit 2 via the connector 103 to extend the single-use time. The elbow 102 combined with the decorative flower 104 enhances the aesthetics, balancing functionality and fashion needs. The mobile APP can display the power of both batteries (main unit + rear hanger) in real time, reminding the user to charge or remove the rear hanger for separate use.

[0043] Traditional taVNS devices rely on ear clips or adhesive pads for fixation, which can easily loosen during exercise. This embodiment addresses this by using a detachable back hook 1 with an arc-shaped band 101 that fits snugly against the occipital bone, creating a dual fixation of the ear and the back of the head, significantly improving stability and preventing slippage during activities such as running and sleeping. Traditional devices have limited battery capacity due to size constraints; this embodiment expands the battery capacity using an auxiliary battery, and the electrical connection between the connector 103 and the interface 204 enables intelligent charging and discharging management, meeting the needs of extended use. Users can choose whether to install the back hook 1 based on their needs. For daily office work or short-term wear, only the main unit 2 is used, maintaining concealment; during exercise, the back hook 1 can be added for enhanced fixation and to prevent slippage.

[0044] The decorative flower 104 on the outside of the elbow 102 enhances the aesthetics of the device and alleviates user anxiety.
