Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a non-invasive bilateral vagus nerve electrical stimulation device. Background Technology

[0002] In the field of neuroscience, the vagus nerve, as one of the longest and most widely distributed autonomic nerves in the human body, plays a crucial role in maintaining homeostasis and responding to changes in the external environment. Vagus nerve stimulation (VNS) is a surgical method that treats epilepsy and other diseases by stimulating the vagus nerve in the neck. This procedure involves locating the vagus nerve in the neck, wrapping electrodes around it, connecting an external stimulator, and continuously releasing pulsed currents to stimulate the vagus nerve. The stimulation is then conducted to the brain, activating a wide range of brain regions to reduce seizures and improve symptoms such as intelligence, memory, language, or cognition. It is increasingly being applied to other neurological diseases and pain management. However, traditional VNS is an invasive procedure with high technical requirements, numerous complications, and limited clinical application. During treatment, transient hoarseness and coughing may occur due to the electrical stimulation; these are usually mild and tolerable, but may cause some discomfort for the patient. The equipment is also expensive, placing a financial burden on patients.

[0003] In recent years, with the continuous development of neuromodulation technology, a non-invasive neuromodulation technique has gradually attracted attention. This technique activates the auricular branch of the vagus nerve by stimulating the cymba conchae of the left ear with electrodes, thereby regulating brain physiological functions and preventing and treating neurological diseases, autoimmune-related diseases, and cardiovascular diseases. This invention provides a simple, portable, and trainable electromyographic signal-gated non-invasive bilateral vagus nerve stimulation device. Utility Model Content

Through simple operation, users can easily switch stimulation modes without complicated settings or adjustments, which also meets different treatment needs and provides greater flexibility.

[0017] 3. Beneficial Effects

[0018] Compared with existing technologies, this invention provides a non-invasive bilateral vagus nerve electrical stimulation device, which has the following beneficial effects:

[0019] This non-invasive bilateral vagus nerve electrical stimulation device achieves non-invasive bilateral vagus nerve electrical stimulation through a wireless electromyography (EMG) acquisition module. When it is not necessary to maintain synchronous stimulation of both ear conchae, the two jacks are used to connect to two electrode earplugs. The pulse generator inputs electrical pulses to the user's ear conchae through the two electrode earplugs to stimulate the vagus nerve. When it is necessary to maintain synchronous stimulation of both ear conchae, the sliding mounting block moves the control box, which in turn moves the pulse adapter to the jack for the corresponding frequency pulse. By controlling the rotation of the transmission threaded rod, the transmission block descends, allowing the plug at the bottom of the pulse adapter to be inserted into the corresponding jack. Then, the plugs corresponding to the two electrode earplugs are inserted into the two jacks at the top of the pulse adapter, thus achieving synchronous low-frequency electrical pulse output from both ears, achieving synchronous stimulation of both ear conchae and realizing synchronous intervention of the bilateral vagus nerve. Through simple operation, users can easily switch between open-loop, closed-loop, or unilateral and bilateral stimulation modes without complex settings or adjustments, meeting personalized treatment needs and providing greater flexibility.

A transmission block 12 is threadedly connected to the transmission threaded rod 10. A pulse adapter 9 is fixedly connected to one outer surface of the transmission block 12.

[0031] Two electrode earpieces 3 are connected to the top of the pulse generator 1 via wires and plugs.

[0032] In a specific embodiment of this utility model, the wireless electromyography (EMG) acquisition module 0 has two button-type EMG acquisition interface terminals 01. These two interface terminals can also be shared charging terminals, allowing charging when an external power adapter is connected to the interface terminal 01. When charging, the indicator light 02 of the wireless acquisition module 0 is red; green when fully charged; yellow when low on; and blue when powered on / working. Using the wireless acquisition module 0 requires operating the switch 03. The electrode earplugs 3 are connected to a wire, the other end of which is connected to a plug. The pulse generator 1 has two jacks on its top. When it is not necessary to maintain synchronous stimulation of both ear conchae, the two jacks are used to connect to the two electrode earplugs 3. The pulse generator 1 inputs electrical pulses to the user's ear conchae through the two electrode earplugs 3 for... When vagus nerve stimulation requires simultaneous stimulation of both cymba conchae, the control box 5 is moved by the sliding mounting block 6. The control box 5 moves the pulse adapter 9 to the corresponding frequency pulse socket. By controlling the rotation of the transmission threaded rod 10, the transmission block 12 is lowered, allowing the plug at the bottom of the pulse adapter 9 to be inserted into the corresponding socket. Then, the plugs corresponding to the two electrode earplugs 3 are inserted into the two sockets at the top of the pulse adapter 9, thus achieving simultaneous low-frequency electrical pulse output in both ears, achieving simultaneous stimulation of both cymba conchae, and realizing simultaneous intervention of the bilateral vagus nerve. Through simple operation, users can easily switch between open-loop, closed-loop, or unilateral and bilateral stimulation modes without complicated settings or adjustments, meeting different treatment needs and providing greater flexibility.

[0033] Specifically, each of the two electrode earpieces 3 has a hanging rod 4 rotatably connected to its top.

[0034] In this embodiment, the hanging rod 4 is used to hang on the user's ears, so that when the two electrode earplugs 3 are worn on the user's ears, they are more stable and less likely to fall off.

[0035] Specifically, two support rods 7 are fixedly connected to the rear side of the mounting plate 2, and the mounting block 6 is slidably sleeved on the two support rods 7.

[0036] In this embodiment, the two support rods 7 ensure that the mounting block 6 remains stable during movement.

[0037] Specifically, a micro motor 8 is fixedly installed on the top of the control box 5, and the output end of the micro motor 8 is fixedly connected to the transmission threaded rod 10.

[0038] In this embodiment, by controlling the micro motor 8 to start, the transmission threaded rod 10 can be driven to rotate.

[0039] Specifically, a limit rod 11 is fixedly connected between the upper and lower inner walls of the control box 5, and the transmission block 12 is slidably sleeved on the limit rod 11.

[0040] In this embodiment, the limiting rod 11 keeps the transmission block 12 stable during its up-and-down movement.

[0041] Specifically, the limit rod 11 is made of stainless steel.

[0042] In this embodiment, the surface of the limiting rod 11 is smooth with low friction, high strength and greater durability.

[0043] Working principle: When it is not necessary to keep both ear conchae cymbidiums stimulated synchronously, the two jacks are used to connect to the two electrode earplugs 3. The pulse generator 1 inputs electrical pulses into the user's ear conchae cymbidiums through the two electrode earplugs 3 to stimulate the vagus nerve. When it is necessary to keep both ear conchae cymbidiums stimulated synchronously, the sliding mounting block 6 drives the control box 5 to move. The control box 5 drives the pulse adapter 9 to move to the jack of the corresponding frequency pulse. By controlling the micro motor 8 to start, the transmission threaded rod 10 rotates, driving the transmission block 12 to descend, so that the plug at the bottom of the pulse adapter 9 is inserted into the corresponding jack. Then the plugs of the two electrode earplugs 3 are respectively... By inserting the two sockets at the top of the pulse adapter 9, low-frequency electrical pulses can be output synchronously to both ears, achieving synchronous stimulation of the concha and cymba in both ears and realizing synchronous intervention of the bilateral vagus nerve. Through simple operation, users can easily switch between open-loop, closed-loop, or unilateral and bilateral stimulation modes without complicated settings or adjustments, meeting different treatment needs and providing greater flexibility. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail.
