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] Transcutaneous electrical stimulation (TES) is a technique that uses the theory of meridians in traditional Chinese medicine to deliver specific pulsed currents to different acupoints in different parts of the body to prevent and treat diseases. It is a new therapy that combines transcutaneous electrical nerve stimulation with acupuncture.

[0003] Existing transcutaneous auricular electrical stimulation (TENS) devices suffer from poor integration. Patients must manually connect the power cord and the wires between the controller and the ear stimulator, making operation inconvenient, time-consuming, and laborious. Furthermore, movement of the head or body during use can easily cause the wires to snag or the ear stimulator to fall off. Some devices only allow single-ear operation, requiring sequential stimulation of the left and right ears, which not only affects the effectiveness but also results in longer stimulation times, hindering long-term use. In addition, the fit and stability of the ear stimulators in existing devices are generally poor, affecting the intensity of electrical stimulation and the accuracy of acupoint correspondence. Utility Model Content

[0004] 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:

[0005] A transcutaneous auricular acupoint electrostimulation device includes a left control unit, a right control unit, and a connecting unit. The left and right control units are respectively connected to the two ends of the connecting unit. The connecting unit can be hung on the neck of the human body so that the left and right control units are respectively positioned on the left and right front sides of the human body. The left ear stimulator is connected to the left control unit through the left connector and is equipped with electrodes to provide electrical stimulation to acupoints on the left ear. The right ear stimulator is connected to the right control unit through the right connector and is equipped with electrodes to provide electrical stimulation to acupoints on the right ear.

[0006] Furthermore, it also includes a control circuit for controlling the electrical stimulator and a power supply component for providing electrical energy. The control circuit is located in one of the control units, the left control unit and the right control unit, and the power supply component is located in the other control unit. The connection unit is provided with wires for electrically connecting the control circuit and the power supply component.

[0007] Furthermore, the left control unit is equipped with a left control circuit for controlling the left ear stimulator and a left power supply component for providing power to the left ear stimulator, and the right control unit is equipped with a right control circuit for controlling the right ear stimulator and a right power supply component for providing power to the right ear stimulator. The left control unit and the right control unit are electrically isolated so that the stimulation currents in the left ear stimulator and the right ear stimulator are independent of each other.

[0008] Furthermore, the left ear stimulator and the left connector are detachably connected via a quick-plug structure, and the right ear stimulator and the right connector are detachably connected via a quick-plug structure.

[0009] Furthermore, the left connector is detachably connected to the left control unit via a quick-plug structure, and the right connector is detachably connected to the right control unit via a quick-plug structure.

[0010] Furthermore, the left ear stimulator is fixedly connected to the left connector, the left connector is fixedly connected to the left control unit, the right ear stimulator is fixedly connected to the right connector, and the right connector is fixedly connected to the right control unit.

[0011] Furthermore, both the left and right control units are equipped with a fixing structure, which is used to stably fix the left and right control units to the left or right front side of the human body.

[0012] Furthermore, the left and right control units are basically the same in weight, volume, and shape, and are arranged symmetrically on the left and right front sides of the human body.

[0013] Furthermore, both the left and right ear stimulators include an in-ear portion, which includes a main body and a first extension portion connected to each other. 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 portion extends from above the main body towards the position of the human cymba concha to fit the first extension portion against the cymba concha. Electrodes are disposed on the main body and / or the first extension portion.

[0014] 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 concha cymba, forming a conical structure. The first extension can elastically deform relative to the main body in the vertical direction so that the upper surface of the first extension fits tightly against the upper wall of the concha cymba. 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.

[0015] Furthermore, an ear hook is connected to the in-ear part, and the left connector and the right connector are respectively connected to the ear hooks of the left ear stimulator and the right ear stimulator. The ear hook can be hung on the outer contour of the ear to enhance the wearing stability of the left and right ear stimulators.

[0016] Furthermore, a clamping component is connected to the ear inlet. One end of the clamping component is connected to the ear inlet, and the other end can be attached to the back of the ear so that the left and right ear stimulators are clamped on the ear.

[0017] Furthermore, the left and right ear stimulators are equipped with music playback modules, which enable the left and right ear stimulators to play music.

[0018] The transcutaneous auricular acupoint electrostimulation device of this invention has the following advantages:

[0019] 1. By coordinating the left control unit, right control unit, and connecting unit, the transcutaneous auricular electrical stimulator can be worn on the neck. This not only greatly improves the integration and miniaturization of the stimulator, but also makes it more convenient to use without needing to hold the device. In addition, the stimulator is more stable to wear and less likely to fall off.

[0020] 2. The design of the in-ear part 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. The left and right ears can be stimulated at the same time, which makes the effect better and can shorten the usage time, which is conducive to long-term use.

[0021] 3. When the left and right ear stimulators are detachably connected to the left and right control units or left and right connectors via a quick-plug structure, it is 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.

[0022] 4. By setting a fixing structure on the left and right control units and setting ear hooks or clamping structures on the left and right ear stimulators, the overall wearing stability of the electrical stimulator is further improved.

[0023] 5. When the left and right control units are set up with electrical isolation, it can ensure that the stimulation current in the left ear stimulator and the right ear stimulator are independent of each other, avoiding crosstalk between currents and the risk of use.

[0028] Figure 5 Schematic diagram of the structure of Example 2 of the ear stimulator Figure 2 . Detailed Implementation

[0029] 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.

[0030] like Figure 1 and Figure 2 As shown, the transcutaneous auricular acupoint electrostimulation device of this utility model includes a left control unit 1, a right control unit 2, and a connecting unit 3. The left control unit 1 and the right control unit 2 are respectively connected to the two ends of the connecting unit 3. The connecting unit 3 can be hung on the neck of the human body so that the left control unit 1 and the right control unit 2 are respectively placed on the left front side and the right front side of the human body. The left ear stimulator 4 is connected to the left control unit 1 through the left connector 5. The left ear stimulator 4 is provided with electrodes 9, which can provide electrical stimulation to acupoints on the left ear of the human body. The right ear stimulator 6 is connected to the right control unit 2 through the right connector 7. The right ear stimulator 6 is provided with electrodes 9, which can provide electrical stimulation to acupoints on the right ear of the human body.

[0031] The connecting unit 3, left connector 5, and right connector 7 can be made of soft materials to better adapt the transcutaneous auricular acupoint stimulator to users of different body types. The connecting unit 3 can also be made of a material with a certain degree of rigidity and pre-designed into a U-shape to improve the wearing stability of the connecting unit 3 when it is hung on the neck.

[0032] The left and right anterior sides of the human body are preferably located below the left and right clavicles. When the left and right control units are positioned in this area, they not only provide stable wear but also facilitate operation of the control buttons and viewing of the display screen. Furthermore, the left and right control units are less likely to directly contact the clavicles, improving wearing comfort. In addition, when the left and right control units are located in the aforementioned areas, the connecting unit 3, left connector 5, and right connector 7 all have suitable lengths, which helps simplify the instrument structure, reduce its size, and decrease the risk of wire snagging.

[0033] Of course, the left and right front sides of the human body also include the left and right sides of the front of the upper body other than the areas mentioned above, such as the left and right clavicles and the area above the clavicles, the left and right chest areas, the left and right rib areas, etc., all of which can achieve stable wearing of the left control unit 1, the right control unit 2 and the connecting unit 3.

[0034] In a preferred embodiment of this invention, the transcutaneous auricular acupoint electrostimulator further includes a control circuit for controlling the electrostimulator and a power supply component for providing electrical energy. The control circuit is disposed in one of the left control unit 1 and the right control unit 2, and the power supply component is disposed in the other control unit. The connecting unit 3 is also provided with wires for electrically connecting the control circuit and the power supply component. The control circuit can control the electrostimulator as a whole, and the power supply component can supply power to the electrostimulator as a whole.

[0035] In another preferred embodiment of this utility model, the left control unit 1 is provided with a left control circuit for controlling the left ear stimulator 4 and a left power supply component for providing power to the left ear stimulator 4, and the right control unit 2 is provided with a right control circuit for controlling the right ear stimulator 6 and a right power supply component for providing power to the right ear stimulator 6. The left control unit 1 and the right control unit 2 are electrically isolated, thereby ensuring that the stimulation currents in the left ear stimulator 4 and the right ear stimulator 6 are independent of each other, avoiding crosstalk between currents and the risk of use.

[0036] Preferably, the left control unit 1 and right control unit 2 of the present invention described above are basically the same in weight, volume, and shape, and are arranged symmetrically on the left and right front sides of the human body. This arrangement allows the left and right control units to have a very symmetrical effect in terms of wearing comfort, which is beneficial for the overall stability of the device on the human body. Specifically, "basically the same" means that the left control unit 1 and right control unit 2 are completely identical in weight, volume, and shape, or have only slight differences. These differences will not cause the left and right control units located on both sides of the human body to have a noticeable sense of sag or asymmetry when the electrical stimulator is worn. "Basically symmetrical" means that the left control unit 1 and right control unit 2 are completely symmetrical on the left and right sides of the human body, or have only a slight positional offset. This offset will not cause the left and right control units located on both sides of the human body to have a noticeable sense of sag or asymmetry when the electrical stimulator is worn.

[0037] Preferably, both the left control unit 1 and the right control unit 2 are provided with a fixing structure (not shown in the figure). The fixing structure can be a clip, pin or magnetic buckle set on the left control unit 1 or the right control unit 2, which is used to stably fix the left control unit 1 and the right control unit 2 to the left front side and the right front side of the human body, thereby further enhancing the stability of the instrument when worn.

[0038] Furthermore, in another preferred embodiment of this invention, the left ear stimulator 4 and the left connector 5 are detachably connected via a quick-connect structure, and the right ear stimulator 6 and the right connector 7 are detachably connected via a quick-connect structure. Alternatively, in another preferred embodiment of this invention, the left connector 5 and the left control unit 1 are detachably connected via a quick-connect structure, and the right connector 7 and the right control unit 2 are detachably connected via a quick-connect structure. This detachable connection configuration allows for easy replacement of different ear stimulators and different acupoint combinations, and also facilitates the replacement of ear stimulators of different sizes to accommodate different ear sizes, thus broadening its applicability.

[0039] Furthermore, in another preferred embodiment of this utility model, the left ear stimulator 4 is fixedly connected to the left connector 5, the left connector 5 is fixedly connected to the left control unit 1, the right ear stimulator 6 is fixedly connected to the right connector 7, and the right connector 7 is fixedly connected to the right control unit 2. This arrangement makes the connection between the ear stimulator and the control unit more stable, resulting in a more stable stimulation effect.

[0040] Furthermore, such as Figures 3 to 5 As shown, in the transcutaneous auricular acupoint electrostimulation device of this utility model, both the left ear stimulator 4 and the right ear stimulator 6 include an ear insertion portion 8. The ear insertion portion 8 includes a connected main body portion 81 and a first extension portion 82. The shape of the main body portion 81 matches the shape of the concha cavity. The side of the main body portion 81 that fits against the human ear is protruding to ensure that the main body portion 81 fits fully against the concha cavity. The first extension portion 82 extends from above the main body portion 81 toward the position of the cymba conchae to ensure that the first extension portion 82 fits against the cymba conchae. Electrodes 9 can be disposed on the main body portion 81 and / or the first extension portion 82.

[0041] When the in-ear part 8 is worn on the left and right ears, the electrodes 9 on the main body 81 can fully conform to the acupoints in the concha cavity, and the electrodes 9 on the first extension 82 can fully conform to the acupoints in the cymba conchae, thereby transmitting the electrical stimulation generated by the electrodes 9 to the corresponding acupoints on the ear. Preferably, the electrodes 9 are corresponding to at least one of the acupoints of the heart, liver, kidney, and spleen on the ear.

[0042] The overall shape of the earpiece 8 not only facilitates the electrode 9's full fit with the concha and cymba conchae, but also allows the main body 81 and the first extension 82 to work together to ensure a more accurate and fixed position of the earpiece 8 relative to the ear. This means the main body 81 and the first extension 82 are less likely to shift or become misaligned inside the ear, ensuring that the electrode 9 on the earpiece 8 accurately corresponds to its designated acupoint. Furthermore, the cooperation between the main body 81 and the first extension 82 enhances the earpiece 8's secure fit, preventing it from easily detaching from the ear and further guaranteeing the effectiveness of acupoint stimulation.

[0043] Furthermore, such as Figure 4 and Figure 5 As shown, in a preferred embodiment of the ear inlet 8, the first extension 82 and the main body 81 are integrally formed and both are made of elastic material. The first extension 82 gradually narrows from the main body 81 toward the concha cymba, forming a conical structure. The first extension 82 can elastically deform relative to the main body 81 in the vertical direction so that the upper surface of the first extension 82 fits tightly against the upper wall of the concha cymba. The ear inlet 8 includes a second extension 83 connected to the main body 81. The second extension 83 is columnar and extends from the main body 81 toward the ear canal of the human ear. The second extension 83 can elastically deform along its own radial direction.

[0044] This design enhances both the secure fit between the earpiece 8 and the ear, and the tightness of the fit between the electrode 9 on the first extension 82 and the cymba conchae. The first extension 82 possesses superior structural strength and resilience, allowing it to better conform to the cymba conchae under elastic pressure, while also reducing the risk of damage from repeated elastic deformation. The second extension 83 provides a positioning and guiding function. When the earpiece 8 is worn, the protruding second extension 83 preferentially contacts the ear, aligning and inserting it into the ear canal. Then, the main body 81 and the first extension 82 smoothly embed into the conchae and cymba conchae, facilitating wear and further enhancing the positioning accuracy and secure fit of the main body 81 and the first extension 82 within the ear. This ensures a more precise and stable fit of the electrode 9 on the earpiece 8 to the ear acupoints.

[0045] Preferably, the main body 81 and the first extension 82 of the ear inlet 8 are both made of elastic materials, such as elastic silicone or an inflatable airbag, so as to make the ear inlet 8 fit better and be more comfortable to wear.

[0046] Furthermore, such as Figure 3As shown, in a preferred embodiment of the ear stimulator, an ear hook 84 is connected to the ear insertion part 8. The ear hook 84 is arc-shaped. The left connector 5 and the right connector 7 are respectively connected to the ear hook 84 of the left ear stimulator 4 and the right ear stimulator 6. The ear hook 84 can be hung on the outer contour of the ear to enhance the wearing stability of the left and right ear stimulators 6.

[0047] Furthermore, such as Figure 4 and Figure 5 As shown, in another preferred embodiment of the ear stimulator, a clamping component 85 is connected to the ear inlet 8. One end of the clamping component 85 is connected to the ear inlet 8, and the other end can be attached to the back of the ear so that the left ear stimulator 4 or the right ear stimulator 6 is clamped on the ear.

[0048] Furthermore, the left ear stimulator 4 and the right ear stimulator 6 are also equipped with music playback modules, which enable the left ear stimulator 4 and the right ear stimulator 6 to play music. For example, a mini-program can be used to control the music playback module via Bluetooth communication to play music while performing electrical stimulation, or a control and storage module for controlling music playback can be set in the left and right control units.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the left control unit 1 and the right control unit 2 are also equipped with a display screen 86 and operation buttons 87. The operation buttons 87 can perform operations such as powering on, powering off, switching stimulation modes, and adjusting stimulation intensity. The display screen 86 can be used to display information such as stimulation mode, stimulation intensity, and stimulation time. It is understandable that setting up a display screen 86 is a preferred setting, as it helps users observe the working status of the instrument.

[0050] The transcutaneous auricular acupoint electrostimulation device of this invention has the following advantages:

[0051] 1. By coordinating the left control unit, right control unit, and connecting unit, the transcutaneous auricular electrical stimulator can be worn on the neck. This not only greatly improves the integration and miniaturization of the stimulator, but also makes it more convenient to use without needing to hold the device. In addition, the stimulator is more stable to wear and less likely to fall off.

[0052] 2. The design of the in-ear part 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. The left and right ears can be stimulated at the same time, which makes the effect better and can shorten the usage time, which is conducive to long-term use.

[0053] 3. When the left and right ear stimulators are detachably connected to the left and right control units or left and right connectors via a quick-plug structure, it is 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.

[0054] 4. By setting a fixing structure on the left and right control units and setting ear hooks or clamping components on the left and right ear stimulators, the overall wearing stability of the electrical stimulator is further improved.

[0055] 5. When the left and right control units are set up with electrical isolation, it can ensure that the stimulation current in the left ear stimulator and the right ear stimulator are independent of each other, avoiding crosstalk between currents and the risk of use.

[0056] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.

[0057] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
