Description

Technical Field

[0001] This utility model relates to the field of transcutaneous acupoint electrical stimulation instruments, and in particular to a transcutaneous ear acupoint electrical stimulation instrument. Background Technology

[0002] In Traditional Chinese Medicine (TCM) theory, the human body is an organic whole, and meridians are the channels through which Qi and blood circulate. The ear is closely connected to the meridians of the internal organs. The *Ling Shu* (Spiritual Pivot) states, "The ear is where all the meridians converge," meaning that the ear is connected to the internal organs through meridians. By stimulating acupoints on the ear, the functions of Qi and blood in the internal organs can be regulated, influencing the body's immune function and thus achieving the purpose of preventing and treating diseases. In current clinical applications, auricular acupuncture has a good analgesic effect on some common painful conditions, such as headaches, trigeminal neuralgia, sciatica, and joint pain. For nervous system disorders such as insomnia, anxiety, and neurasthenia, auricular acupuncture can regulate nerve function and improve symptoms. For some digestive system disorders, such as stomach pain, bloating, indigestion, constipation, and diarrhea, auricular acupuncture can also regulate gastrointestinal function. Therefore, the clinical applications of auricular acupuncture are very broad.

[0003] While acupuncture has a good safety and effectiveness in clinical applications, some patients may experience fainting during the procedure. Furthermore, acupuncture requires inserting needles into the skin, which can cause pain and affect patients' willingness to undergo treatment. In addition, acupuncture must be performed by professionals, limiting flexibility in terms of treatment location and time, making it inconvenient and difficult for patients to adhere to the treatment regimen.

[0004] Transcutaneous electrical stimulation (TES) is a technique guided by Traditional Chinese Medicine (TCM) meridian theory. It involves delivering specific pulsed currents to different acupoints on different parts of the body to prevent and treat diseases. It is a novel therapy combining transcutaneous electrical nerve stimulation with acupuncture. Existing transcutaneous auricular electrical stimulation devices have poor integration. Patients need to connect the power cord and the wires between the controller and the ear stimulator themselves, which is inconvenient, time-consuming, and laborious. Furthermore, if the patient moves their head or body during use, the wires can easily get caught, or the ear stimulator can fall off. Some devices can only operate on one ear at a time, requiring sequential stimulation of the left and right ears. This not only affects the effectiveness but also results in longer stimulation times, making long-term use difficult. In addition, the fit and stability of the ear stimulators in existing devices are generally poor, affecting the intensity of the electrical stimulation and the accuracy of acupoint targeting. Utility Model Content

[0005] The purpose of this invention is to provide a miniaturized, integrated transcutaneous auricular acupoint electrostimulation device that can be directly worn on the head and neck to simultaneously provide electrical stimulation to both ears. The specific technical solution is as follows:

[0006] A transcutaneous auricular acupoint electrical stimulator includes a left ear stimulator, a right ear stimulator, and a controller. The left ear stimulator is connected to the controller via a left connector, and the right ear stimulator is connected to the controller via a right connector. The controller is positioned corresponding to the back of the head and neck of the human body and can control the left and right ear stimulators to provide electrical stimulation to the left and right ears of the human body, respectively.

[0007] Furthermore, the controller includes a front shell, a rear shell, and circuit boards and power supply components disposed within the front and rear shells. The rear shell corresponds to the back of the human head and neck, while the front shell is located on the side of the controller away from the human body. The front shell is equipped with a display screen and operation buttons.

[0008] Furthermore, the controller's rear shell has an arc-shaped concave structure in the middle, and protrusions on the left and right sides of the rear shell to match the shape of the back of the human head and neck. The surface of the rear shell that contacts the back of the human head and neck is designed as an anti-slip surface.

[0009] Furthermore, the left connector and / or right connector include connecting wires, which are positioned corresponding to the left or right posterior side of the human head and neck, and the connecting wires are equipped with adjustment buttons for adjusting the intensity of electrical stimulation.

[0010] Furthermore, the connecting cable is made of rigid material and is designed to fit the head and neck area of ​​the human body.

[0011] Furthermore, the left ear stimulator and / or right ear stimulator includes an in-ear portion, which includes a connected main body and a first extension. The shape of the main body matches the shape of the concha cavity. The side of the main body that fits against the human ear is protruded to fit the main body against the concha cavity. The first extension extends from above the main body toward the position of the human cymba concha to fit the first extension against the cymba concha.

[0012] Furthermore, the first extension is integrally formed with the main body and is made of elastic material. The first extension gradually narrows from the main body toward the ear armor, forming a conical structure.

[0013] Furthermore, the first extension can undergo elastic deformation in the vertical direction relative to the main body, so that the upper surface of the first extension fits tightly against the upper wall of the ear armor boat.

[0014] Furthermore, stimulation electrodes are provided on the main body and / or the first extension of the ear-entry part, and the electrodes correspond to acupoints on the ear.

[0015] Furthermore, the electrodes are set to correspond to at least one of the acupoints on the ear, namely the heart acupoint, liver acupoint, kidney acupoint, and spleen acupoint.

[0016] Furthermore, the ear canal includes a second extension connected to the main body. The second extension is columnar and extends from the main body toward the ear canal of the human ear. The second extension can elastically deform along its own radial direction.

[0017] Furthermore, the left ear stimulator and / or right ear stimulator also include a clamping part, which is positioned corresponding to the back of the human ear. The clamping part is connected to the ear insertion part through a connecting part, which is an elastically deformable curved arc structure. Under the elastic action of the connecting part, a clamping force can be generated between the clamping part and the ear insertion part to clamp the human ear.

[0018] Furthermore, the clamping part is provided with a first arc surface and a second arc surface. The first arc surface is provided corresponding to the rear surface of the human ear, and the second arc surface is provided corresponding to the head surface behind the human ear.

[0019] Furthermore, the connecting part includes a connecting rod and a connecting head. The connecting head is connected to the side of the ear inlet away from the human ear via a connecting post. The outer diameter of the connecting post is smaller than the outer diameter of the ear inlet and the connecting head, so that an annular groove is formed between the connecting head and the ear inlet. The two ends of the connecting rod are connected to the clamping part and the connecting head, respectively.

[0020] Furthermore, the left ear stimulator and / or right ear stimulator are connected to the controller via a quick-plug assembly.

[0021] Furthermore, the left ear stimulator and / or right ear stimulator includes an in-ear portion and a clamping portion, the clamping portion being connected to the in-ear portion via a connecting portion, one end of the quick-release assembly being disposed on the clamping portion, and the other end being disposed on the left or right connector.

[0022] The transcutaneous auricular acupoint electrostimulation device of this invention has the following advantages:

[0023] 1. By integrating and miniaturizing the controller with the left and right ear stimulators, the electrical stimulator can be worn as a whole on the head and neck, eliminating the need to hold the controller by hand, reducing wiring connections, and greatly improving the convenience of using the instrument.

[0024] 2. Acupoints can be stimulated on both ears simultaneously, resulting in better effects and shorter usage time, which is conducive to long-term use.

[0025] 3. The design of the earpiece makes the left and right ear stimulators comfortable and secure to wear, and the acupoints are accurately located, which helps to ensure the stability and effectiveness of electrical stimulation.

[0026] 4. The design of the clamping part can further improve the wearing stability of the ear stimulator, making it less likely to shift or fall off. The shape of the clamping part can make the clamping feel more comfortable and reduce the discomfort caused by wearing it for a long time.

[0027] 5. The left and right ear stimulators are connected to the controller via a quick-plug structure, which makes it easy to replace different ear stimulators and perform different combinations of acupoint stimulation. It is also easy to replace ear stimulators of different sizes to adapt to different ear sizes, making it widely applicable. Attached Figure Description

[0041] To better understand the purpose, structure, and function of this utility model, the transcutaneous auricular acupoint electrostimulation device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] like Figures 1 to 5 As shown, the transcutaneous auricular acupoint electrostimulation device of this invention includes a left ear stimulator 1, a right ear stimulator 2, and a controller 3. The left ear stimulator 1 is connected to the controller 3 via a left connector 4, and the right ear stimulator 2 is connected to the controller 3 via a right connector 5. The controller 3 is positioned corresponding to the back of the head and neck of the human body, and can control the left ear stimulator 1 and the right ear stimulator 2 to provide electrical stimulation to the left and right ears of the human body respectively. When using the transcutaneous auricular acupoint electrostimulation device of this invention, the controller 3 is worn on the back of the head and neck of the human body, so that it fits and is fixed to the human body. The left ear stimulator 1 is worn on the left ear, fitting snugly against the left ear, and the right ear stimulator 2 is worn on the right ear, fitting snugly against the right ear. By operating the controller 3, the left ear stimulator 1 and the right ear stimulator 2 operate in a certain mode to simultaneously provide electrical stimulation to the acupoints on the left and right ears.

[0043] The term "back of the head and neck" is preferably the transitional position between the head and neck on the side of the back of the body. It can also refer to the back of the head or the back of the neck. By wearing the controller 3 on the above-mentioned position, the controller 3 can be integrated and miniaturized with the left and right ear stimulators. When using the instrument, there is no need to hold the controller 3, and the number of wires is reduced, which greatly improves the convenience of using the instrument.

[0044] Specifically, such as Figure 2 and Figure 3 As shown, the outer shell of the controller 3 includes a front shell and a rear shell 31 that interlock with each other. The rear shell 31 corresponds to the back of the human head and neck, while the front shell is located on the side of the controller away from the human body. The center of the rear shell 31 has an arc-shaped concave structure, and the left and right sides of the rear shell 31 are convex to match the shape of the back of the human head and neck. With the above-mentioned arrangement, when the controller 3 is worn on the human body, it can fit more closely to the back of the head and neck area and increase the surface area of ​​the controller 3 in contact with the human body, thereby improving the stability of wearing and making the controller 3 less likely to fall off. Preferably, the surface of the rear shell 31 that contacts the back of the human head and neck is a non-slip surface. For example, the surface of the rear shell 31 can be a frosted silicone surface or have a non-slip pattern.

[0045] It should be noted that in this preferred embodiment, the front shell and rear shell 31 of the controller 3 are divided into two relatively independent parts, which are joined together to form the whole shell. This is to facilitate production and assembly, and at the same time save costs. It can be understood that, under the premise of meeting the production and assembly requirements, the shell of the controller 3 can be a single integral part, or it can be set as three or more parts that can be combined with each other to form the shell of the controller 3.

[0046] Furthermore, such as Figure 1 As shown, the back shell of the controller 3 fits snugly against the human body, while the front shell of the controller 3 is equipped with operation buttons 32 and a display screen 33. The operation buttons 32 can perform functions such as powering on / off, switching stimulation modes, and adjusting stimulation intensity. The display screen 33 can display information such as stimulation mode, stimulation intensity, and stimulation time. It is understood that providing the display screen 33 is a preferred configuration, helping the user observe the instrument's working status. However, the controller 3 may also be equipped without the display screen 33, without affecting the instrument's basic functions.

[0047] The controller 3 also includes a connected circuit board and a power supply component, which are located inside the front and rear shells. The power supply component can be a battery, preferably a rechargeable battery, to further improve the ease of use of the instrument. The circuit board is equipped with a wireless communication unit, a sound unit, and a light unit. Through the wireless communication unit, the controller 3 can be controlled by other wireless communication methods besides buttons, such as a remote control, a mobile app, or an APP. The sound unit can provide sound or voice prompts, such as power on / off prompts, and prompts for the start and end of electrical stimulation. The light unit can provide light indicators, such as low battery prompts and charging prompts.

[0048] Furthermore, in this invention, the left ear stimulator 1 and the right ear stimulator 2 have essentially the same structure, as described below. Figures 6 to 10 Taking the right ear stimulator 2 as an example, the specific structure of the left / right ear stimulator in this utility model will be described in detail.

[0049] like Figure 6 and Figure 7 As shown, the right ear stimulator 2 includes an ear inlet, which comprises a main body 21 and a first extension 22 connected to each other. The shape of the main body 21 matches the shape of the concha cavity of the human ear, and the side of the main body 21 that fits against the human ear protrudes, so that the main body 21 can fit fully against the concha cavity. The first extension 22 extends from above the main body 21 toward the cymba concha of the human ear, so that the first extension 22 fits against the cymba concha. Stimulation electrodes 6 are provided on the surface of the ear inlet that fits against the human ear, and the electrodes correspond to acupoints on the ear.

[0050] Specifically, electrodes 6 can be disposed on the main body 21 and / or the first extension 22. When the earpiece is worn on the left or right ear, the electrodes 6 disposed on the main body 21 can fully conform to the acupoints in the concha cavity, and the electrodes 6 disposed on the first extension 22 can fully conform to the acupoints in the cymba conchae, thereby allowing the electrical stimulation generated by the electrodes 6 to be transmitted to the corresponding acupoints on the ear. Preferably, the electrodes 6 are disposed corresponding to at least one of the acupoints of the heart, liver, kidney, and spleen in the ear.

[0051] The overall shape of the aforementioned earpiece not only facilitates a close fit between the electrode 6 and the conchae and cymba conchae, but also ensures that the structure of the main body 21 and the first extension 22 works in harmony, allowing for a more accurate and fixed position of the entire earpiece relative to the ear. This means that the main body 21 and the first extension 22 are less likely to shift or become misaligned inside the ear during wear, thus guaranteeing that the electrode 6 accurately corresponds to its designated acupoint. Simultaneously, the cooperation between the main body 21 and the first extension 22 also enhances the overall stability of the earpiece, preventing it from easily detaching from the ear and further ensuring the effectiveness of acupoint stimulation.

[0052] Furthermore, the first extension 22 can elastically deform in the vertical direction relative to the main body 21. That is, the first extension 22 can elastically deform in the vertical direction relative to the cymba conchae of the human ear, so that the upper surface of the first extension 22 can fit tightly against the upper wall of the cymba conchae. This arrangement not only enhances the wearing stability between the in-ear portion and the human ear, but also enhances the tightness of the fit between the electrode 6 on the first extension 22 and the cymba conchae.

[0053] Preferably, the end of the first extension 22 that connects to the main body 21 is wider and gradually narrows from the main body 21 toward the cymba conchae, forming a conical structure. The first extension 22 and the main body 21 are integrally formed, with a smooth transition at the connection. This design not only makes the appearance more aesthetically pleasing and more comfortable to wear, but also helps to strengthen the structural strength and resilience of the first extension 22, allowing it to better conform to the cymba conchae under elastic action, while being less prone to damage due to repeated elastic deformation.

[0054] Preferably, both the main body 21 and the first extension 22 of the earpiece are made of elastic materials, such as elastic silicone or an inflatable airbag, to improve the fit of the earpiece and make it more comfortable to wear.

[0055] Furthermore, the earpiece also includes a second extension 23 connected to the main body 21. The second extension 23 is columnar and extends from the main body 21 toward the ear canal. The second extension 23 has a positioning and guiding function. When wearing the earpiece, the protruding second extension 23 can preferentially contact the ear. First, the second extension 23 is aligned and inserted into the ear canal. Then, the main body 21 and the first extension 22 can be inserted into the concha and cymba conchae of the ear. This not only makes it easy to wear, but also further enhances the positioning accuracy and wearing stability of the main body 21 and the first extension 22 in the ear, making the electrode 6 on the earpiece fit the ear acupoints more accurately and stably.

[0056] Preferably, the second extension 23 can elastically deform along its own radial direction. For example, the second extension 23 is made entirely of elastic silicone or other elastic materials, or the second extension 23 can be configured as a hollow columnar structure. The above configuration allows the second extension 23 to elastically deform to a certain extent when squeezed by the ear canal sidewall, fully conforming to the ear canal, thereby improving the positioning effect of the second extension 23 and the wearing comfort.

[0057] Furthermore, such as Figures 6 to 9 As shown, the right ear stimulator 2 also includes a clamping part 24, which is disposed on the back side of the human ear. The clamping part 24 is connected to the ear insertion part through a connecting part 25. The connecting part 25 is a flexible curved structure. Under the elastic action of the connecting part 25, a clamping force can be generated between the clamping part 24 and the ear insertion part to clamp the human ear, so that the right ear stimulator 2 can be worn more stably and comfortably on the human ear.

[0058] Preferably, the clamping part 24 is provided with a first arc surface and a second arc surface. The first arc surface is corresponding to the posterior surface of the human ear, and the second arc surface is corresponding to the surface of the head behind the human ear. When wearing the right ear stimulator 2, since the first arc surface on the clamping part 24 is approximately the same curvature as the posterior surface of the human ear, and the second arc surface is approximately the same curvature as the surface of the head behind the human ear, the foreign body sensation of the clamping part 24 can be reduced, and the wearing comfort can be improved.

[0059] Furthermore, such as Figure 9 and Figure 10As shown, the connecting part 25 includes a connecting rod 251 and a connecting head 252. The connecting head 252 is connected to the side of the earpiece away from the ear via a connecting post 253. The outer diameter of the connecting post 253 is smaller than the outer diameter of the earpiece and the connecting head 252, so that an annular groove 254 is formed between the connecting head 252 and the earpiece. The two ends of the connecting rod 251 are connected to the clamping part 24 and the connecting head 252, respectively. When wearing the earpiece, the connecting head 252 can be easily held. By pinching the connecting head 252, force is applied to insert the earpiece into the ear, and the position of the earpiece in the ear is adjusted. After the earpiece is properly worn, it can be basically embedded in the inside of the ear. At this time, the annular groove 254 can be locked onto the cartilage on the outer edge of the concha. This design makes it easier to wear or remove the earpiece and also makes it easier to adjust the position of the earpiece in the ear.

[0060] Furthermore, the electrodes 6 on the ear can be set to one, two, or more, with different electrodes 6 corresponding to different acupoints on the ear. The specific number and placement of the electrodes 6 can be combined according to different corresponding symptoms. Specifically, for example... Figure 8 The first embodiment of the right ear stimulator 2 shown includes two electrodes 6, both disposed on the main body 21 of the ear canal, corresponding to the heart and liver acupoints in the human ear, respectively. Figure 11 In the second embodiment of the right ear stimulator 2 shown, there are two electrodes 6, both disposed on the main body 21 of the ear insertion portion, corresponding to the heart and spleen acupoints in the human ear, respectively. Figure 12 In the third embodiment of the right ear stimulator 2 shown, the electrodes 6 include two, one disposed on the main body 21 and the other on the first extension 22, corresponding to the heart and kidney acupoints in the human ear, respectively. Furthermore, as... Figure 13 In the fourth embodiment of the right ear stimulator 2 shown, the electrode 6 can be configured as a perfect circle or as a circular shape. Figure 8 , Figure 11 and Figure 12 The oblong shape shown can, of course, be set to other forms such as ellipse, rectangle, or ring according to design needs.

[0061] Preferably, the electrode 6 may protrude from the surface of the ear canal to enhance the fit between the electrode 6 and the ear skin. Preferably, the electrode 6 may be configured with an elastic structure, such as a spring-loaded retractable electrode 6, or a metal electrode 6 covered with elastic conductive silicone.

[0062] Furthermore, such as Figures 1 to 4As shown, the left ear stimulator 1 in this invention has a basically the same structure as the right ear stimulator 2 described above, and the two are symmetrically arranged on the left and right sides of the controller 3. Of course, it is a preferred embodiment that the left ear stimulator 1 and the right ear stimulator 2 are symmetrically arranged on both sides of the controller 3 with basically the same structure. The ear stimulator structure described above can also be provided only on the left ear stimulator 1 or only on the right ear stimulator 2.

[0063] Furthermore, the left ear stimulator 1 and / or the right ear stimulator 2 are detachably connected to the controller 3 via a quick-release assembly. Specifically, the quick-release assembly is located at the connection point between the left connector 4 and the left ear stimulator 1 and / or the right connector 5 and the right ear stimulator 2; or, the quick-release assembly is located at the connection point between the left connector 4 and the controller 3 and / or the right connector 5 and the controller 3; or, the quick-release assembly is located in the middle of the left connector 4 and / or the right connector 5. As a preferred embodiment, one end of the quick-release assembly is located on the clamping part 24 of the left / right ear stimulator, and the other end is located on the left / right connector. Based on the above configuration, different users can conveniently replace left / right ear stimulators of different sizes according to their own ear size, or conveniently replace left / right ear stimulators with different acupoint combinations according to different treatment needs.

[0064] Preferred, such as Figures 7 to 9 As shown, the right ear stimulator 2 is provided with a quick-connect interface 7. Specifically, the quick-connect interface 7 is located on the clamping part 24 of the right ear stimulator 2, near the lower part of the clamping part 24. Placing the quick-connect interface 7 here makes it easier to insert and remove the connector, and also helps to reduce the pulling of the quick-connect structure and the left / right connector on the ear canal.

[0065] Furthermore, such as Figures 1 to 4 As shown, the left connector 4 and the right connector 5 have essentially the same structure and are symmetrically arranged on the left and right sides of the controller 3. Specifically, the left connector 4 includes a connecting wire, which is positioned corresponding to the left rear side of the human head and neck, and the right connector 5 includes a connecting wire, which is positioned corresponding to the right rear side of the human head and neck. Preferably, the connecting wire is made of a rigid material so that it can fit more closely to the human head and neck, reducing the risk of the wire getting caught.

[0066] Furthermore, the connecting line is equipped with adjustment buttons for adjusting the intensity of electrical stimulation. Preferably, the adjustment buttons include a raised or recessed boost button and a debuff button, which are arranged adjacent to each other. The raised or recessed area of ​​the boost button is larger than that of the debuff button, so that the boost button and debuff button can be identified by touch, facilitating adjustment.

[0067] Of course, it is a preferred embodiment that the left connector 4 and the right connector 5 are symmetrically arranged on both sides of the controller 3 with basically the same structure. The above-mentioned connector structure can also be arranged only on the left connector 4 or only on the right connector 5.

[0068] In this invention, the left ear stimulator 1 and the right ear stimulator 2 preferably adopt the above-described combination structure of the ear inlet, the clamping part 24, and the connecting part 25, which can achieve a comfortable, stable, and accurate acupoint-corresponding wearing effect. Of course, the left ear stimulator 1 and the right ear stimulator 2 can also only have the above-described ear inlet, with the left connecting part 4 and the right connecting part 5 respectively connected to the ear inlet of the left and right ears; or, the clamping part 24 and the connecting part 25 on the left ear stimulator 1 and the right ear stimulator 2 can also be configured as ear hooks, that is, the connecting part 25 hangs above the ear, and the clamping part 24 is located at the end of the connecting part 25, abutting against the posterior surface of the ear or the surface of the head behind the ear.

[0069] The transcutaneous auricular acupoint electrostimulation device of this invention has the following advantages:

[0070] 1. By integrating and miniaturizing the controller with the left and right ear stimulators, the electrical stimulator can be worn as a whole on the head and neck, eliminating the need to hold the controller by hand, reducing wiring connections, and greatly improving the convenience of using the instrument.

[0071] 2. Acupoints can be stimulated on both ears simultaneously, resulting in better effects and shorter usage time, which is conducive to long-term use.

[0072] 3. The design of the earpiece ensures that the left and right ear stimulators are comfortable and secure to wear, and the acupoints are accurately located, which helps to ensure the stability and effectiveness of electrical stimulation.

[0073] 4. The design of the clamping part can further improve the wearing stability of the ear stimulator, making it less likely to shift or fall off. The shape of the clamping part can make the clamping feel more comfortable and reduce the discomfort caused by wearing it for a long time.

[0074] 5. The left and right ear stimulators are connected to the controller via a quick-plug structure, which makes it easy to replace different ear stimulators and perform different combinations of acupoint stimulation. It is also easy to replace ear stimulators of different sizes to adapt to different ear sizes, making it widely applicable.

[0075] The present invention has been further described above with reference to specific embodiments.
