Description

Technical Field

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

[0002] Acupuncture therapy has good safety and effectiveness in clinical applications. In traditional Chinese medicine theory, the human body is an organic whole, and the meridians are the channels for the circulation of qi and blood. Among them, the head is the "meeting place of all yang" and the ear is the "gathering place of all meridians". By synergistically stimulating the acupoints on the head and ears, the qi and blood of the whole body can be regulated in combination, thereby enhancing the therapeutic effect of acupuncture.

[0003] However, some patients may experience fainting during acupuncture, and the need to insert needles into the skin can cause pain, which may affect their willingness to undergo treatment. Furthermore, acupuncture requires professional personnel to perform the procedure, 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 (TENS) 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 instruments for electrical stimulation of acupoints on the head and ears are often poorly integrated. Patients need to connect the power cord and the wires between the controller and the acupoint stimulator themselves, making operation inconvenient, time-consuming, and laborious. Furthermore, if the patient moves their head or body during use, problems such as wire snagging or the acupoint stimulator detaching can easily occur.

[0005] In addition, when wearing the device, users need to adjust the relative position of the stimulator to the head or ear to ensure that the stimulator corresponds to each acupoint. Due to the large individual differences in the human head, existing electrical stimulation devices are difficult to adjust conveniently and quickly, and to ensure the accurate correspondence between the stimulator and the acupoints, which in turn affects the intensity of electrical stimulation and the stability of electrical stimulation output. Utility Model Content

[0006] The purpose of this invention is to provide a miniaturized, integrated transcutaneous transauricular acupoint electrostimulation device that can be directly worn on the head to simultaneously provide electrical stimulation to the head and both ears. The specific technical solution is as follows:

[0007] A percutaneous cranioauricular acupoint electrostimulation device includes a main body of the device positioned opposite to the circumference of the human head. The main body includes a forehead stimulator and a first adjustment component. The forehead stimulator can electrically stimulate acupoints on the forehead. The first adjustment component can adjust the circumference of the main body. A craniotop stimulator is provided on the main body, which can electrically stimulate acupoints on the top of the skull. The craniotop stimulator includes a second adjustment component, which can adjust the circumference of the craniotop stimulator. An ear stimulator is provided at a position close to both ears of the main body, which can electrically stimulate acupoints on the ears.

[0008] Furthermore, the forehead stimulator is positioned opposite the front of the human head, and the first adjustment component is positioned opposite the back of the human head. The two ends of the forehead stimulator are rotatably connected to the two ends of the first adjustment component, and the first adjustment component can be extended or shortened.

[0009] Furthermore, the forehead stimulator includes a front shell and a rear shell that interlock with each other. The rear shell is located near the forehead and has a first electrode assembly that can fit against acupoints on the forehead. A receiving space is formed between the front shell and the rear shell, and a controller and a power supply assembly are installed within the receiving space.

[0010] Furthermore, the two ends of the second adjustment component are rotatably connected to the main body of the instrument. The second adjustment component is equipped with a second electrode group that can fit with the acupoints near the top of the human skull. The second adjustment component can be extended or shortened.

[0011] Furthermore, the second adjustment component includes a top shell and an adjustment band. The first end of the adjustment band is rotatably connected to the forehead stimulator, and the second end is retractably connected to the top shell. The second electrode group is located on the side of the top shell opposite to the top of the human skull.

[0012] Furthermore, the ear stimulator is connected to the main body of the instrument via a quick-plug assembly.

[0013] Furthermore, the ear stimulator includes an ear inlet, which includes a main body and a first extension 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 extends from above the main body toward the position of the human cymba concha to fit the first extension against the cymba concha.

[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 ear armor, forming a conical structure. 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.

[0015] 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.

[0016] Furthermore, the ear stimulator also includes a clamping part, which is positioned on the back side 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.

[0017] The transcutaneous cranial auricular acupoint electrical stimulator of this invention has the following advantages:

[0018] 1. By integrating and miniaturizing the forehead stimulator, cranial stimulator, and ear stimulators for both ears, the electrical stimulator can be worn as a whole on the head, reducing wiring connections and greatly improving the ease of use of the instrument.

[0019] 2. By setting the first adjustment component and the second adjustment component to a rotating connection, the instrument as a whole can not only adjust the size of the head circumference and the top of the skull, but also adjust the engagement position of the instrument body with the head and the position of the electrodes at the top of the skull by rotation, making the instrument more comfortable to wear and more accurate in corresponding with acupoints.

[0020] 3. The design of the ear stimulator's insertion 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 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 feeling more comfortable and reduce the discomfort caused by wearing it for a long time.

[0021] 4. The ear stimulator is connected to the instrument body 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

[0035] To better understand the purpose, structure, and function of this utility model, the transcutaneous cranial auricular acupoint electrostimulation device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 5 As shown, the percutaneous cranioauricular acupoint electrostimulation device of this utility model includes an instrument body 1 positioned opposite to the circumference of the human head. The instrument body 1 includes a forehead stimulator 2 and a first adjustment component 3. The forehead stimulator 2 can electrically stimulate acupoints on the forehead, and the first adjustment component 3 can adjust the circumference of the instrument body 1. When the user wears the electrostimulation device, adjusting the first adjustment component 3 can adjust the instrument body 1 to approximately the same size as the user's head circumference, achieving stable wearing, and simultaneously ensuring that the electrodes on the forehead stimulator 2 fit the acupoints on the forehead.

[0037] The main body 1 of the instrument is also equipped with a cranial stimulator 4, which can electrically stimulate acupoints on the top of the human skull. The cranial stimulator 4 includes a second adjustment component 5, which can adjust the size of the cranial stimulator 4. When the user wears the electrical stimulator, the cranial stimulator 4 is clipped above the human head. By adjusting the second adjustment component 5, the cranial stimulator 4 can be adjusted to approximately the same height as the top of the user's skull to achieve stable wearing and ensure that the electrodes on the cranial stimulator 4 can fit in contact with the acupoints on the top of the human head.

[0038] An ear stimulator 6 is installed at a position close to the human ear on the main body 1. The ear stimulator 6 can be worn on the human ear to electrically stimulate acupoints on the human ear.

[0039] The percutaneous cranial auricular acupoint electrostimulation device of this utility model integrates and miniaturizes the forehead stimulator 2, the cranial vertex stimulator 4, and the ear stimulators 6 of the left and right ears, so that the electrostimulation device can be worn on the head as a whole, reducing the number of wires and greatly improving the convenience of the instrument.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the forehead stimulator 2 is semi-circular in shape and is positioned opposite the front of the human head. The first adjustment component 3 is also semi-circular in shape and is positioned opposite the back of the human head. The two ends of the forehead stimulator 2 are rotatably connected to the two ends of the first adjustment component 3, and the first adjustment component 3 can be extended or shortened. When the user wears the electrical stimulator, they can adjust the relative position of the first adjustment component 3 to the back of the head by slightly rotating it, and adjust the extension and retraction length of the first adjustment component 3 to position it in a comfortable and stable position.

[0041] Specifically, such as Figure 5 As shown, the first adjustment component 3 includes a first strap 31, a second strap 32, a cylindrical gear 33, and a knob 34. One end of the first strap 31 and the second strap 32 are rotatably connected to both ends of the forehead stimulator 2, and the other ends overlap each other. A rack structure is provided at the overlapping end of the first strap 31 and the second strap 32. The cylindrical gear 33 meshes with the rack structure. The knob 34 is connected to the cylindrical gear 33. By rotating the knob 34, the cylindrical gear 33 can be rotated, thereby causing relative displacement of the rack structure, making the first strap 31 and the second strap 32 relatively tighten or relatively separate, achieving the effect of adjusting the circumference of the instrument body 1. Of course, the first adjustment component 3 can also be configured as other retractable structures, such as an adjustable telescopic strap.

[0042] Furthermore, such as Figure 3 and Figure 4As shown, the forehead stimulator 2 includes a front shell 21 and a rear shell 22 that interlock with each other. The rear shell 22 is located near the forehead and has a first electrode assembly 7 that fits snugly against acupoints on the forehead. A receiving space is formed between the front shell 21 and the rear shell 22, within which a controller and a power supply assembly are housed. The front shell 21 may also have operation buttons and a display screen. The operation buttons can be used to turn the device on / off, switch stimulation modes, and adjust stimulation intensity. The display screen can show information such as stimulation mode, stimulation intensity, and stimulation time. It is understood that having a display screen is a preferred option, helping the user observe the device's operating status; however, the display screen can also be omitted without affecting the device's basic functions.

[0043] The controller includes a circuit board on which wireless communication units, sound units, and lighting units can be installed. Through the wireless communication unit, the controller can be controlled via wireless communication methods other than buttons, such as a remote control, a mobile app, or a mobile application. The sound unit provides audio or voice prompts, such as power on / off prompts, and indications of the start and end of electrical stimulation. The lighting unit provides light indicators, such as low battery warnings and charging status. The power supply component can be a battery, preferably a rechargeable battery, to further improve the ease of use of the instrument.

[0044] Furthermore, such as Figure 1 As shown, the two ends of the second adjustment component 5 are rotatably connected to the main body 1 of the instrument. A second electrode group 8, which can conform to acupoints, is positioned near the top of the human skull on the second adjustment component 5. The second adjustment component 5 can be extended or shortened. When the user wears the electrical stimulator, they can adjust the relative position of the second electrode group 8 on the second adjustment component 5 to the top of the human skull by rotating the second adjustment component 5. By adjusting the extension / retraction length of the second adjustment component 5, the second electrode group 8 can be accurately aligned with and stably fitted to the acupoints on the top of the skull.

[0045] Specifically, such as Figure 5 As shown, the second adjustment component 5 includes a top shell 51 and an adjustment band 52. The second electrode group 8 is disposed on the side of the top shell 51 opposite to the top of the human skull. Preferably, there are two adjustment bands 52. The first end of the two adjustment bands 52 is rotatably connected to the forehead stimulator 2, and the second end is telescopically connected to the top shell 51. A spring piece 53 is provided on the second end of the adjustment band 52. The spring piece 53 is provided with a protrusion 54. Multiple grooves are provided in parallel at the position where the top shell 51 connects with the adjustment band 52. The protrusion 54 on the spring piece 53 can be embedded into the groove in the top shell 51. By pulling or pushing the adjustment band 52, the protrusion 54 on the spring piece 53 can be engaged with different grooves, thereby achieving the effect of adjusting the telescopic length of the second adjustment component 5.

[0046] Preferably, the first electrode group 7 on the forehead stimulator 2 corresponds to the Yintang acupoint on the human body, and the second electrode group 8 on the cranial stimulator 4 corresponds to the Baihui acupoint on the human body.

[0047] Furthermore, such as Figures 1 to 3 As shown in the figure, in this utility model, the ear stimulators 6 corresponding to the left and right ears of the human body have basically the same structure. The following description, in conjunction with... Figures 6 to 10 Taking the right ear stimulator as an example, the specific structure of the ear stimulator 6 in this utility model will be described in detail.

[0048] like Figure 6 and Figure 7 As shown, the right ear stimulator includes an ear inlet, which comprises a main body 61 and a first extension 62 connected to each other. The shape of the main body 61 matches the shape of the concha cavity of the human ear, and the side of the main body 61 that fits against the human ear protrudes to ensure that the main body 61 fits fully against the concha cavity. The first extension 62 extends from above the main body 61 toward the cymba concha of the human ear, so that the first extension 62 fits against the cymba concha. Stimulation electrodes 9 are provided on the surface of the ear inlet that fits against the human ear, and the electrodes correspond to acupoints on the ear.

[0049] Specifically, electrodes 9 can be disposed on the main body 61 and / or the first extension 62. When the earpiece is worn on the left or right ear, the electrodes 9 disposed on the main body 61 can fully conform to the acupoints in the concha cavity, and the electrodes 9 disposed on the first extension 62 can fully conform to the acupoints in the cymba conchae, thereby allowing the electrical stimulation generated by the electrodes 9 to be transmitted to the corresponding acupoints in the ear. Preferably, the electrodes 9 are disposed corresponding to at least one of the acupoints of the heart, liver, kidney, and spleen in the ear.

[0050] The overall shape of the aforementioned earpiece not only facilitates a close fit between the electrode 9 and the conchae and cymba conchae, but also ensures that the structure of the main body 61 and the first extension 62 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 61 and the first extension 62 are less likely to shift or displace inside the ear during wear, guaranteeing that the electrode 9 accurately corresponds to its designated acupoint. Furthermore, the cooperation between the main body 61 and the first extension 62 enhances the overall stability of the earpiece, preventing it from easily detaching from the ear and further ensuring the effectiveness of acupoint stimulation.

[0051] Furthermore, the first extension 62 can elastically deform in the vertical direction relative to the main body 61, that is, the first extension 62 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 62 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 9 on the first extension 62 and the cymba conchae.

[0052] Preferably, the end of the first extension 62 that connects to the main body 61 is wider and gradually narrows from the main body 61 toward the cymba conchae, forming a conical structure. The first extension 62 and the main body 61 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 62, allowing it to better conform to the cymba conchae under elastic action, while being less prone to damage due to repeated elastic deformation.

[0053] Preferably, both the main body 61 and the first extension 62 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.

[0054] Furthermore, the earpiece also includes a second extension 63 connected to the main body 61. The second extension 63 is columnar and extends from the main body 61 toward the ear canal. The second extension 63 has a positioning and guiding function. When wearing the earpiece, the protruding second extension 63 can preferentially contact the ear. First, the second extension 63 is aligned and inserted into the ear canal. Then, the main body 61 and the first extension 62 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 61 and the first extension 62 in the ear, making the electrodes 9 on the earpiece fit the acupoints of the ear more accurately and stably.

[0055] Preferably, the second extension 63 can elastically deform along its own radial direction. For example, the second extension 63 is made entirely of elastic silicone or other elastic materials, or the second extension 63 can be configured as a hollow columnar structure. The above configuration allows the second extension 63 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 and wearing comfort of the second extension 63.

[0056] Furthermore, such as Figures 6 to 9As shown, the right ear stimulator also includes a clamping part 64, which is disposed on the back side of the human ear. The clamping part 64 is connected to the ear insertion part through a connecting part 65. The connecting part 65 is a flexible curved structure. Under the elastic action of the connecting part 65, a clamping force can be generated between the clamping part 64 and the ear insertion part to clamp the human ear, so that the right ear stimulator can be worn more stably and comfortably on the human ear.

[0057] Preferably, the clamping part 64 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, since the first arc surface on the clamping part 64 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 64 can be reduced, and the wearing comfort can be improved.

[0058] Furthermore, such as Figure 9 and Figure 10 As shown, the connecting part 65 includes a connecting rod 651 and a connecting head 652. The connecting head 652 is connected to the side of the earpiece away from the ear via a connecting post 653. The outer diameter of the connecting post 653 is smaller than the outer diameter of the earpiece and the connecting head 652, so that an annular groove 654 is formed between the connecting head 652 and the earpiece. The two ends of the connecting rod 651 are connected to the clamping part 64 and the connecting head 652, respectively. When wearing the earpiece, the connecting head 652 can be easily held. By pinching the connecting head 652, 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 654 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.

[0059] Furthermore, the electrodes 9 on the ear can be set to one, two, or more, with different electrodes 9 corresponding to different acupoints on the ear. The specific number and placement of the electrodes 9 can be combined according to different corresponding symptoms. Specifically, for example... Figure 8 The first embodiment of the right ear stimulator shown includes two electrodes 9, both disposed on the main body 61 of the ear canal, corresponding to the heart and liver acupoints in the human ear, respectively. Figure 11 The second embodiment of the right ear stimulator shown includes two electrodes 9, both disposed on the main body 61 of the ear canal, corresponding to the heart and spleen acupoints in the human ear, respectively. Figure 12 In the third embodiment of the right ear stimulator shown, the electrodes 9 include two, one disposed on the main body 61 and the other on the first extension 62, 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 shown, electrode 9 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.

[0060] Preferably, the electrode 9 may protrude from the surface of the ear canal to enhance the fit between the electrode 9 and the ear skin. Preferably, the electrode 9 may be configured with an elastic structure, such as a spring-loaded retractable electrode 9, or a metal electrode 9 covered with elastic conductive silicone.

[0061] Furthermore, such as Figures 1 to 3 As shown, the left ear stimulator in this invention has a structure that is basically the same as the right ear stimulator described above, and the two are symmetrically arranged on the left and right sides of the instrument body 1. Of course, it is a preferred embodiment that the left ear stimulator and the right ear stimulator are symmetrically arranged on the two sides of the instrument body 1 with basically the same structure. The ear stimulator 6 structure described above can also be arranged only on the left ear stimulator or only on the right ear stimulator.

[0062] Furthermore, the left ear stimulator and / or right ear stimulator are detachably connected to the instrument body 1 via a quick-connect assembly. Specifically, the ear stimulator 6 is connected to the instrument body 1 via a connecting cable, and the quick-connect assembly can be located at the connection point between the instrument body 1 and the connecting cable, or at the connection point between the ear stimulator 6 and the connecting cable. Based on the above configuration, different users can easily replace the left / right ear stimulators of different sizes according to their own ear size, or conveniently replace the left / right ear stimulators with different acupoint combinations according to different treatment needs.

[0063] Preferred, such as Figures 7 to 9 As shown, the right ear stimulator is provided with a quick-connect interface 66. Specifically, the quick-connect interface 66 is located on the clamping part 64 of the right ear stimulator, near the lower part of the clamping part 64. Placing the quick-connect interface 66 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.

[0064] In this invention, the left and right ear stimulators preferably employ the aforementioned combination structure of the ear inlet, clamping part 64, and connecting part 65, which achieves a comfortable, stable, and accurately acupoint-corresponding wearing effect. Of course, the left and right ear stimulators may also only have the aforementioned ear inlet.

[0065] The transcutaneous cranial auricular acupoint electrical stimulator of this invention has the following advantages:

[0066] 1. By integrating and miniaturizing the forehead stimulator, cranial stimulator, and ear stimulators for both ears, the electrical stimulator can be worn as a whole on the head, reducing wiring connections and greatly improving the ease of use of the instrument.

[0067] 2. By setting the first adjustment component and the second adjustment component to a rotating connection, the instrument as a whole can not only adjust the size of the head circumference and the top of the skull, but also adjust the engagement position of the instrument body with the head and the position of the electrodes at the top of the skull by rotation, making the instrument more comfortable to wear and more accurate in corresponding with acupoints.

[0068] 3. The design of the ear stimulator's insertion 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 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 feeling more comfortable and reduce the discomfort caused by wearing it for a long time.

[0069] 4. The ear stimulator is connected to the instrument body 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.

[0070] 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. The various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.

[0071] 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.
