Description

Technical Field

[0001] This invention relates to the field of neurostimulator technology, and particularly to a threadless, thread-controlled ear-hook vagus nerve stimulator. Background Technology

[0002] Vagus nerve stimulation (VNS), as an effective neuromodulation technique, has been widely used in the treatment of neurological disorders such as epilepsy and depression. Traditional VNS stimulation often uses implantable pulse generators, requiring surgical implantation of stimulating electrodes into the jugular groove and connection to a pulse generator buried under the chest wall. While this method has proven effective, it suffers from significant surgical trauma, high risk of infection, high treatment costs, and potential side effects such as hoarseness, coughing, and difficulty breathing, limiting its application to a wider range of patients. In recent years, percutaneous auricular VNS stimulation has gained widespread attention due to its non-invasive and safe characteristics. This technique utilizes the anatomical features of the auricle, particularly the cymba conchae and cavum conchae, where the auricular branch of the vagus nerve is distributed. Electrical stimulation is applied through surface electrodes to activate the vagus nerve and achieve therapeutic goals. Existing non-invasive ear-hook stimulators typically employ an integrated or semi-integrated design, with a fixed structure. However, existing devices of this type still have significant drawbacks: the shape of the human auricle varies greatly from person to person, and a fixed-shape stimulator cannot provide precise and stable electrode-skin contact for all users, resulting in uneven stimulation effects, and even falling off during daily activities due to poor fit; rigid or semi-rigid structures are difficult to wear comfortably for extended periods, easily creating pressure points on the auricle, causing pain or discomfort, and affecting patient compliance; most devices lack effective physiological signal feedback mechanisms, and cannot intelligently adjust stimulation parameters according to the patient's real-time physiological state, so the treatment effect needs to be optimized. At the same time, their interaction capabilities with mobile smart devices are weak, making it inconvenient for patients to conduct personalized management and remote medical monitoring; and the charging methods of the devices are often inconvenient, lacking dedicated charging and storage solutions, making it inconvenient for users to carry when going out, and easily lost or damaged due to improper storage.

[0003] Therefore, there is an urgent need in this field for a threadless, remotely controlled ear-hook vagus nerve stimulator that can overcome the aforementioned shortcomings. It should be able to flexibly conform to the shape of different users' auricles, ensuring stable contact between the stimulating electrodes and the target acupoints. Simultaneously, it should possess intelligent control capabilities and connect to the user's terminal wirelessly to achieve convenient personalized treatment and device management. Furthermore, an integrated charging and storage solution is needed to improve ease of use. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention adopts the following technical solution: a threadless, controllable ear-hook vagus nerve stimulator, comprising two wearing mechanisms for wearing and a charging mechanism for charging the wearing mechanisms. The wearing mechanism includes a coarse-plated copper tube and a stimulator, with a charging pad disposed on the stimulator. The coarse-plated copper tube is a bendable copper tube. The charging mechanism includes a charging box, with an upper placement slot for charging the stimulator disposed on the top of the charging box. During charging, the charging pad is in contact with the upper placement slot.

[0005] Furthermore, the wearing mechanism also includes a fine-plated copper tube, which is a bendable copper tube. Multiple silicone blocks are provided on the coarse-plated copper tube and the fine-plated copper tube. The silicone blocks are made of silicone. Large silicone blocks are also provided on the coarse-plated copper tube and the fine-plated copper tube. Silicone ear loops are fixedly installed on the large silicone blocks.

[0006] Furthermore, the surface contours of the silicone block and the large silicone block are elongated teardrop shapes, with a wide and arc-shaped upper part that gradually narrows downwards from the wide upper area, without sharp edges, making it easier to fit the human ear. The silicone block and the large silicone block are provided with two through holes for the coarse-plated copper tube and the fine-plated copper tube to pass through.

[0007] Furthermore, the coarse-plated copper tube and the fine-plated copper tube are rotatably mounted with elliptical contacts at their ends. An earpiece for playing music is installed inside the elliptical contacts. Acupoint contacts are installed on the elliptical contacts, and an inner wire is fixedly installed on the acupoint contacts. The coarse-plated copper tube has a hollow structure, and the inner wire passes through the hollow structure of the coarse-plated copper tube into the stimulator. A lower circuit board is installed inside the stimulator, and the inner wire is electrically connected to the lower circuit board.

[0008] Furthermore, the lower circuit board is provided with two supporting pillars, and an upper circuit board is fixedly installed on the supporting pillars. A signal chip is provided on the lower circuit board, and a Bluetooth module is provided on the upper circuit board. Multiple resistors are provided on the lower and upper circuit boards. A battery is placed inside the stimulator, and a removable battery cover is provided on the stimulator. The lower circuit board is electrically connected to the upper circuit board, the Bluetooth module is electrically connected to the upper circuit board, the signal chip is electrically connected to the lower circuit board, the resistors are electrically connected to the lower and upper circuit boards, the battery is electrically connected to the lower circuit board and the supporting pillars, and the battery is electrically connected to the charging pad.

[0009] Furthermore, the stimulator can be removed along the ends of the coarse-plated copper tube and the fine-plated copper tube. When using the wearing mechanism, the stimulator is inserted through the fine-plated copper tube and the coarse-plated copper tube, and the bottom of the coarse-plated copper tube and the fine-plated copper tube are bent to prevent the stimulator from falling out.

[0010] In use, the stimulator is first inserted through the thin and thick copper tubes. The bottoms of the thin and thick copper tubes are bent to prevent the stimulator from falling out. The thin and thick copper tubes are then bent into a shape that fits the auricle. Multiple silicone blocks and a large silicone block are then attached to the auricle. The flexibility of the silicone blocks helps to better adapt to the contour of the auricle. The silicone ear hooks secure the device to the auricle for a more stable and comfortable fit. After wearing, the acupoint contacts are attached to the acupoints next to the ear to measure the pulse rate. The stimulator's operating frequency is adjusted based on the pulse rate. Once the device is in place, it connects to the user's mobile phone via Bluetooth. The user can then control the stimulator to turn it on. The acupoint contacts transmit the pulse signal to the lower circuit board via internal wires. The signal chip controls the stimulator's operating frequency, stimulating the vagus nerve for epilepsy treatment. The stimulator is powered by a battery.

[0011] Furthermore, the charging mechanism also includes a magnet fixedly installed on the charging box. An upper switch plate and a side switch plate are rotatably installed on the charging box. The side switch plate and the upper switch plate are provided with patches that can be attracted by the magnet. When the side switch plate and the upper switch plate are closed, the magnet attracts the side switch plate and the upper switch plate.

[0012] Furthermore, the charging box is provided with two placement slots for placing the wearing mechanism, a power display screen is provided on the charging box, a main circuit board and a soft-pack battery are fixedly installed inside the charging box, a removable back cover is provided at the rear of the charging box, the soft-pack battery is electrically connected to the main circuit board, the main circuit board is electrically connected to the power display screen, the main circuit board is electrically connected to the upper placement slot, multiple limiting blocks are provided on the charging box, and a charging interface for charging the soft-pack battery is provided on the side of the charging box.

[0013] When the stimulator needs to be charged, turn on the upper and side switch plates. Bend the thin and thick plated copper tubes into the shape of a placement slot. Place the wearing mechanism (with the stimulator removed) into the placement slot, and then place the two stimulators between the four limit blocks. At this time, the charging pad is in contact with the upper placement slot, and the upper placement slot is powered by the soft-pack battery. The upper placement slot charges the stimulator through the charging pad. During charging, the power level of the stimulator is read through the upper placement slot and the data is transmitted to the main circuit board. The main circuit board then transmits the data to the power display screen, which displays the power level of the stimulator. After placing the stimulator and wearing mechanism into the charging box, the upper and side switch plates can be turned off. When the side and upper switch plates are closed, the magnets attract the patches inside the side and upper switch plates, keeping the side and upper switch plates closed and preventing the wearing mechanism and stimulator placed in the charging box from falling out.

[0014] The beneficial effects of this invention compared with the prior art are: (1) The wearing mechanism of this invention uses flexible thick and thin plated copper tubes as the main frame, combined with silicone blocks with elongated teardrop shape and no sharp edges and large silicone blocks, to achieve a high degree of personalized fit. Users can precisely bend the copper tubes according to their own ear shape, so that the silicone parts can fit the ear contour tightly with their flexibility, eliminating the pressure caused by the traditional fixed structure. At the same time, the silicone ear hook design further enhances the stability of wearing, ensuring that it is not easy to fall off in daily activities, which significantly improves the patient's willingness to use it for a long time and treatment compliance; (2) This invention integrates physiological signal detection and wireless thread control functions. The acupoint contact point can monitor the pulse rate next to the ear in real time and transmit the signal to the signal chip through the internal wire. The signal chip can dynamically adjust the operation of the stimulator according to the physiological indicator of pulse. The frequency makes the stimulation therapy no longer fixed and can be precisely and adaptively adjusted according to the user's real-time physiological state, thereby improving the treatment effect; (3) The charging mechanism set in this invention has a placement slot and a limiting block in the charging box to ensure that the stimulator and the wearing mechanism can be placed safely and neatly, and is firmly locked by the magnetic upper switch plate and side switch plate to prevent accidental opening and falling when carrying. When charging, the power display can intuitively display the remaining power of the stimulator, which is convenient for users to manage and greatly improves the portability and convenience of daily use of the device, ensuring seamless connection of treatment; (4) The stimulator set in this invention is a core functional module that can be inserted and removed along the copper tube, forming a modular structure. The stimulator integrates a Bluetooth module, which allows users to wirelessly control the switch and parameter settings of the stimulator through smart devices such as mobile phones, making the operation extremely convenient.

[0027] like Figures 3-6 As shown, the wearing mechanism also includes a fine-plated copper tube 102, which is a bendable copper tube. Multiple silicone blocks 105 are provided on the coarse-plated copper tube 101 and the fine-plated copper tube 102. The silicone blocks 105 are made of silicone.

[0028] like Figures 3-6As shown, the surface contours of silicone block 105 and large silicone block 106 are elongated teardrop shapes, with a wide and arc-shaped upper part that gradually narrows downwards from the wide upper area. They are without sharp edges, which makes it easier to fit the ear. Silicone block 105 and large silicone block 106 are provided with two through holes for the coarse-plated copper tube 101 and the fine-plated copper tube 102 to pass through.

[0029] like Figures 3-6 As shown, elliptical contacts 108 are rotatably mounted at the ends of the coarse-plated copper tube 101 and the fine-plated copper tube 102. An earphone for playing music is installed inside the elliptical contacts 108. An acupoint contact 109 is provided on the elliptical contacts 108. An inner wire 110 is fixedly installed on the acupoint contact 109. The coarse-plated copper tube 101 has a hollow structure. The inner wire 110 passes through the hollow structure of the coarse-plated copper tube 101 and enters the stimulator 103. A lower circuit board 113 is provided inside the stimulator 103. The inner wire 110 is electrically connected to the lower circuit board 113.

[0030] like Figures 3-6 As shown, the lower circuit board 113 has two supporting pillars 114, and the upper circuit board 115 is fixedly mounted on the supporting pillars 114. The lower circuit board 113 has a signal chip 118, and the upper circuit board 115 has a Bluetooth module 117. Multiple resistors 116 are provided on the lower circuit board 113 and the upper circuit board 115. A battery 112 is placed inside the stimulator 103, and the stimulator 103 has a removable battery cover 111. The lower circuit board 113 is electrically connected to the upper circuit board 115, the Bluetooth module 117 is electrically connected to the upper circuit board 115, the signal chip 118 is electrically connected to the lower circuit board 113, the resistors 116 are electrically connected to the lower circuit board 113 and the upper circuit board 115, the battery 112 is electrically connected to the lower circuit board 113 and the supporting pillars 114, and the battery 112 is electrically connected to the charging plate 104.

[0031] like Figures 3-6 As shown, the stimulator 103 can be removed along the ends of the coarse-plated copper tube 101 and the fine-plated copper tube 102. When using the wearing mechanism, the stimulator 103 is inserted through the fine-plated copper tube 102 and the coarse-plated copper tube 101, and the bottom of the coarse-plated copper tube 101 and the fine-plated copper tube 102 is bent to prevent the stimulator 103 from falling out.

[0032] In use, first insert the stimulator 103 through the thin-plated copper tube 102 and the coarse-plated copper tube 101. Bend the bottom of the coarse-plated copper tube 101 and the thin-plated copper tube 102 to prevent the stimulator 103 from falling out. First, bend the thin-plated copper tube 102 and the coarse-plated copper tube 101 into a shape that fits the auricle. Then, attach multiple silicone blocks 105 and a large silicone block 106 to the auricle. When fitting the auricle, the flexibility of the silicone blocks 105 and 106 better adapts to the contour of the auricle. The silicone ear hook 107 clips the ear to make the wearing more secure and comfortable. After wearing, The acupoint contact 109 is attached to the acupoint next to the ear to measure the pulse rate, thereby changing the working frequency of the stimulator 103 according to the pulse rate. After the wearing mechanism is worn, it is connected to the user's mobile phone via Bluetooth module 117. The user's mobile phone controls the stimulator 103 to turn on. The acupoint contact 109 transmits the pulse signal to the lower circuit board 113 through the internal wire 110. The signal chip 118 controls the working frequency of the stimulator 103. The stimulator 103 stimulates the vagus nerve to treat epilepsy. The stimulator 103 is powered by battery 112.

[0033] like Figure 2 , Figure 7 , Figure 8 As shown, the charging mechanism also includes a magnet 204 fixedly installed on the charging box 201. An upper switch plate 205 and a side switch plate 203 are rotatably installed on the charging box 201. The side switch plate 203 and the upper switch plate 205 are provided with patches that can be attracted by the magnet 204. When the side switch plate 203 and the upper switch plate 205 are closed, the magnet 204 attracts the side switch plate 203 and the upper switch plate 205.

[0034] like Figure 2 , Figure 7 , Figure 8 As shown, the charging case 201 has two placement slots 202 for placing the wearing mechanism. The charging case 201 has a power display screen 210. The main circuit board 207 and the soft-pack battery 208 are fixedly installed inside the charging case 201. The rear of the charging case 201 has a removable back cover 209. The soft-pack battery 208 is electrically connected to the main circuit board 207. The main circuit board 207 is electrically connected to the power display screen 210. The main circuit board 207 is electrically connected to the upper placement slot 206. The charging case 201 has multiple limiting blocks 211. The side of the charging case 201 has a charging interface for charging the soft-pack battery 208.

[0035] When it is necessary to charge the stimulator 103, turn on the upper switch plate 205 and the side switch plate 203, bend the thin-plated copper tube 102 and the coarse-plated copper tube 101 into the shape of the placement slot 202, place the wearing mechanism with the stimulator 103 removed into the placement slot 202, and then place the two stimulators 103 between the four limit blocks 211. At this time, the charging plate 104 is in contact with the upper placement slot 206, and the upper placement slot 206 is powered by the soft-pack battery 208. The upper placement slot 206 charges the stimulator 103 through the charging plate 104. During charging, the power level of the stimulator 103 is read through the upper placement slot 206, and... The data is transmitted to the main circuit board 207, which then transmits the data to the power display screen 210. The power display screen 210 shows the power level of the stimulator 103. After the stimulator 103 and the wearing mechanism are placed in the charging case 201, the upper switch plate 205 and the side switch plate 203 can be turned off. When the side switch plate 203 and the upper switch plate 205 are closed, the magnet 204 attracts the patches inside the side switch plate 203 and the upper switch plate 205, keeping the side switch plate 203 and the upper switch plate 205 in a closed state, so that the wearing mechanism and the stimulator 103 placed in the charging case 201 will not fall out.

[0036] The working principle of the threadless, remotely controlled ear-hook vagus nerve stimulator disclosed in this invention is as follows: In use, the upper switch plate 205 and the side switch plate 203 are opened, and the wearing mechanism and stimulator 103 are removed respectively. First, the stimulator 103 is inserted through the thin-plated copper tube 102 and the coarse-plated copper tube 101. The bottoms of the coarse-plated copper tube 101 and the thin-plated copper tube 102 are bent to prevent the stimulator 103 from falling out. The thin-plated copper tube 102 and the coarse-plated copper tube 101 are then bent into a shape that fits the auricle. Then, multiple silicone blocks 105 and a large silicone block 106 are attached to the auricle. When fitting the auricle, the flexibility of the silicone blocks 105 and 106 better adapts to the contour of the auricle. The silicone ear hook 107 clips onto the auricle, making the wearing more secure and comfortable. After wearing, the acupoint contact 109 is attached to the acupoints next to the ear to measure the pulse rate, thereby changing the working frequency of the stimulator 103 according to the pulse rate. After the wearing mechanism is worn, it connects to the user's mobile phone via Bluetooth module 117. The user's mobile phone controls the stimulator 103 to turn on. The acupoint contact 109 transmits the pulse signal to the lower circuit board 113 through the internal wire 110. The signal chip 118 controls the working frequency of the stimulator 103. The stimulator 103 stimulates the vagus nerve to treat epilepsy. The stimulator 103 is powered by battery 112. When it is necessary to charge the stimulator 103, turn on the upper switch plate 205 and the side switch plate 203, bend the thin-plated copper tube 102 and the coarse-plated copper tube 101 into the shape of the placement slot 202, place the wearing mechanism with the stimulator 103 removed into the placement slot 202, and then place the two stimulators 103 between the four limit blocks 211. At this time, the charging plate 104 is in contact with the upper placement slot 206, and the upper placement slot 206 is powered by the soft-pack battery 208. The upper placement slot 206 charges the stimulator 103 through the charging plate 104. During charging, the power level of the stimulator 103 is read through the upper placement slot 206, and... The data is transmitted to the main circuit board 207, which then transmits the data to the power display screen 210. The power display screen 210 shows the power level of the stimulator 103. After the stimulator 103 and the wearing mechanism are placed in the charging case 201, the upper switch plate 205 and the side switch plate 203 can be turned off. When the side switch plate 203 and the upper switch plate 205 are closed, the magnet 204 attracts the patches inside the side switch plate 203 and the upper switch plate 205, keeping the side switch plate 203 and the upper switch plate 205 in a closed state, so that the wearing mechanism and the stimulator 103 placed in the charging case 201 will not fall out.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
