Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to an acupuncture needle device with a micro-current stimulation function. Background Art

[0002] In traditional Chinese medicine, current therapy is a modern treatment method that is widely used in pain management, rehabilitation, and auxiliary treatment of various diseases. Traditional acupuncture current therapy usually relies on an external power source connected to the acupuncture needles through wires to achieve electrical stimulation of specific acupoints. However, this method has some shortcomings.

[0003] First, the timing of the application of the current is usually not synchronized with the acupuncture action, which may lead to unsatisfactory stimulation effects. Patients feel the current stimulation only after the acupuncture, resulting in a misalignment of the timing of the current and the acupuncture effect, which in turn affects the treatment effect.

[0004] Secondly, traditional electric current therapy often lacks flexibility in regulating the current intensity, and the operator is unable to adjust the current intensity in a timely manner according to the patient's specific response, which may result in insufficient or excessive stimulation, causing discomfort to the patient.

[0005] In addition, the depth of acupuncture has a significant impact on the conduction and stimulation of the current, and traditional methods fail to fully consider this factor. The physical differences between different patients and the changes in the depth of acupuncture make the transmission effect of the current vary greatly, resulting in insufficient individualization of the treatment effect.

[0006] In this context, it is particularly important to develop a new type of acupuncture needle device that can achieve a high degree of synchronization between current and acupuncture action, and has flexible current regulation and depth adaptability. This will bring higher therapeutic effects and patient comfort to acupuncture therapy, and promote the application and development of acupuncture in modern medicine. Summary of the invention

[0007] The purpose of the present invention is to provide an acupuncture needle device with a microcurrent stimulation function, which, through reasonable structural design and scientific logical analysis, achieves the improvement of the effectiveness, safety and patient experience of acupuncture therapy, and provides important support for the modernization of acupuncture technology.

[0008] The technical solution adopted by the present invention is as follows: An acupuncture needle device with a microcurrent stimulation function, for a single-handed needle insertion technique, comprises a positive finger sleeve and a negative finger sleeve; the positive finger sleeve is mounted on the index finger of an operator, and its length allows it to cover the base of the finger; the negative finger sleeve is mounted on the middle finger of the operator, and its length allows it to cover the base of the finger; a positive electrode sheet is embedded on the side of the positive finger sleeve close to the thumb; a negative electrode block is embedded at the position of the negative finger sleeve corresponding to the fingertip; the positive electrode sheet and the negative electrode block are electrically connected to the positive and negative electrodes of a portable power source respectively; during acupuncture using the single-handed needle insertion technique, the acupuncture needle device forms a current loop between the positive electrode of the portable power source, the acupuncture needle, the acupuncture point, the middle finger touch point and the negative electrode of the portable power source, so that the acupuncture points are synchronously stimulated by current during the acupuncture process.

[0009] Among them, an elastic band is connected to the opposite sides of the proximal intersegmental joint of the index finger corresponding to the positive finger sleeve and the proximal phalanx of the middle finger corresponding to the negative finger sleeve. During the one-handed needle insertion technique, the elastic band is stretched and the restoring force of the elastic band is used to increase the insertion speed of the acupuncture needle.

[0010] Among them, the negative electrode finger sleeve is embedded with a magnetic guide groove corresponding to the middle finger pulp; the diameters of the upper and lower ends of the guide groove are larger than the middle part, forming an expanded groove structure; the guide groove is used to guide and maintain the insertion direction of the acupuncture needle.

[0011] The voltage of the portable power source can be adjusted manually, and when not adjusted manually, the voltage is automatically kept constant.

[0012] Wherein, the main material of the positive electrode finger sleeve and the negative electrode finger sleeve is elastic insulating material.

[0013] Wherein, the main material of the positive electrode finger cover and the negative electrode finger cover is silicone or TPU.

[0014] The positive electrode sheet is made of a silver-plated polymer or a woven metal material, which has good conductivity and flexibility.

[0015] Wherein, the negative electrode block is made of copper or silver-plated material.

[0016] Wherein, the elastic band is made of chloroprene rubber or elastic fabric.

[0017] The portable power source is worn at the waist, and thin conductive wires are respectively connected to the positive electrode sheet and the negative electrode sheet, and then enter the sleeve from the back of the hand, and extend through the arm to the waist to connect the positive and negative electrodes of the portable power source.

[0018] Wherein, the outer surface of the negative electrode block is a curved surface.

[0019] An auxiliary acupuncture method, using the acupuncture needle device, comprises the following steps: ①Put the positive finger sleeve on the index finger and the negative finger sleeve on the middle finger, and the length of both reaches the base of the fingers; ②Pinch the handle of the acupuncture needle with the thumb and index finger, and the positive electrode on the positive finger sleeve will make electrical contact with the needle handle; move the middle finger downward, and press the lower part of the acupuncture needle from the side with the middle finger, so that the lower part of the acupuncture needle is embedded in the guide groove. Due to the magnetism of the guide groove, this process does not require deliberate alignment, and the lower part of the acupuncture needle can automatically slide into the guide groove; during the downward movement of the middle finger, the proximal intersegmental joint of the index finger moves away from and backwards relative to the proximal phalanx of the middle finger, driving the elastic band to stretch; ③ Use the strength of the index finger and middle finger to quickly insert the acupuncture needle downward into the skin of the acupuncture point; during this process, the middle finger is simultaneously moved downward to touch the patient's skin, so that the negative electrode block contacts the patient's skin; and during this process, the elastic band recovers, and the stretch recovery effect of the elastic band is used to apply appropriate force to increase the initial velocity of the acupuncture needle and reduce the patient's pain; at the moment the acupuncture needle penetrates the patient's acupuncture point, a current loop is formed between the positive electrode of the portable power supply, the acupuncture needle, the acupuncture point, the middle finger touch point and the negative electrode of the portable power supply, and the acupuncture point is stimulated synchronously with current during the acupuncture process; ④ When the acupuncture needle is kept in the acupuncture point, the middle finger is used as a fulcrum to perform the necessary lifting, pulling and twisting operations on the acupuncture needle. During this process, the circuit is not broken, and the current stimulation to the acupuncture point is maintained; during the lifting process, since the voltage of the portable power supply remains constant and the current is mainly conducted through the needle tip, the resistance varies with the depth of the acupuncture needle, resulting in a fitting effect that the current increases with the depth of the acupuncture needle; ⑤ After releasing the acupuncture needle, the current circuit is automatically disconnected and the next needle is applied.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Microcurrent stimulation enhances the therapeutic effect The positive and negative finger sleeves in the acupuncture needle device are connected to a portable power source, respectively, and a complete current loop is formed through the positive and negative blocks. When the acupuncture needle is inserted into the acupuncture point, microcurrent stimulation is provided through this loop. Microcurrent can stimulate nerve endings, promote local blood circulation and metabolism, and improve the overall efficacy of acupuncture. The presence of current stimulation makes the treatment process not limited to mechanical puncture, but also increases the intensity of physiological reactions.

[0021] 2. Reduce the pain of needle insertion An elastic band is used to connect the positive and negative finger sleeves, and the needle insertion speed is increased through stretching and recovery force. Since the pain nerves are mainly distributed in the epidermis and dermis of the skin, fast and smooth needle insertion can significantly reduce the patient's pain and reduce the psychological pressure on the patient. The design of the elastic band can achieve a more natural needle insertion action while applying force, avoiding pain caused by improper force application.

[0022] 3. Automatic alignment and guidance stability The guide groove built into the negative finger sleeve has a flared groove structure, with the diameter of the upper and lower ends larger than the middle. This design can automatically guide the insertion direction of the acupuncture needle and reduce the operator's errors in alignment. Through the use of magnetic materials, the guide groove can help the acupuncture needle slide in smoothly, avoiding unnecessary repeated attempts and additional discomfort to the patient.

[0023] In addition, the use of magnetic plastic in the guide groove has the following advantages: Integrity of the current loop: Magnetic plastics are non-conductive and therefore do not affect the formation of the current loop. This ensures that during acupuncture, the current between the positive and negative electrodes flows steadily without interruption or interference due to the conductivity of the material.

[0024] Lightness: The lightness of magnetic plastic makes the entire acupuncture device easier for the operator to operate, reducing the burden on the hands. The lightweight design allows the operator to apply the needle more flexibly, improving the comfort and efficiency of the operation.

[0025] Moderate magnetism: The magnetism of magnetic plastic is relatively small, so it will not drive the acupuncture needle too much when withdrawing the hand, avoiding the needle from tilting and the patient's pain. This is very important because after acupuncture, the operator needs to withdraw the needle quickly and steadily, and moderate magnetism can reduce this error.

[0026] Convenient and flexible operation: The design of the guide groove allows the acupuncture needle to slide in smoothly when inserted without the operator having to perform complex alignment. This allows the operator to focus on the acupuncture technique, improving the fluidity and flexibility of the entire process.

[0027] 4. Flexibility and adjustability of portable power The portable power supply is connected to the positive electrode and the negative electrode through a thin conductive wire, and the voltage can be adjusted manually. The design of the portable power supply allows it to be used in different occasions and meet a variety of clinical needs. At the same time, the adjustability of the voltage allows the operator to adjust the appropriate current intensity according to the specific situation of the patient to optimize the treatment effect.

[0028] 5. The fitting effect of current variation with depth During the acupuncture process, the depth of the acupuncture needle is different, and the resistance changes, resulting in changes in the current size. As the acupuncture needle goes deeper, the local resistance increases, and the current increases accordingly. This dynamically changing current stimulation can adapt to the depth of acupuncture, further improving the treatment effect. This design ensures that effective current stimulation can still be maintained when stimulating deep acupoints, which is in line with the conditioning principles of traditional Chinese medicine acupuncture.

[0029] The main differences between the current change of this patent application and traditional acupuncture current therapy are as follows: Synchronous current stimulation: This device instantly forms a current loop during acupuncture, achieving current stimulation synchronized with the acupuncture operation. Traditional therapies usually apply current after acupuncture, which may lead to inconsistent stimulation time and effect. This synchronization helps to enhance the treatment effect and improve the patient's comfort.

[0030] Current depth adaptability: Since the current changes with the change of acupuncture needle depth, this device can automatically adjust the current according to the different resistances. Traditional therapies often cannot adapt to different acupuncture depths, which may lead to insufficient or excessive stimulation. This design improves the adaptability of the current and helps to provide personalized treatment according to individual differences. Traditional electroacupuncture therapy cannot automatically achieve current changes with depth in operation, because the traditional method uses an electroacupuncture instrument with a fixed current output, and its current intensity is manually adjusted by the operator and will not automatically adjust according to the change of acupuncture depth. The principle is to connect the electrode to the needle handle of the acupuncture needle, use the electroacupuncture instrument to generate a current of constant frequency and intensity, and introduce it into the acupuncture point through the acupuncture needle. The current adjustment is usually manually set by the operator according to the patient's tolerance and treatment goals, including current intensity, waveform type (such as continuous wave, intermittent wave), frequency, etc. The current output by the electroacupuncture instrument is relatively constant and will not automatically adjust the intensity due to changes in the depth of acupuncture needle insertion.

[0031] 6. Simplify the operation process The device is designed for one-handed operation, and the structure of the positive and negative electrode finger sleeves simplifies the acupuncture process. This design makes acupuncture more efficient, and the operator can focus more on the treatment without having to worry too much about the complexity of the operation. This is especially important for rapid acupuncture in a clinical environment.

[0032] 7. Promote the modernization of acupuncture By combining modern technology with traditional techniques, more advanced acupuncture equipment has been created. This combination not only improves the scientificity and effectiveness of acupuncture, but also promotes the modernization and internationalization of traditional acupuncture skills, and provides new ideas for the application of acupuncture in modern medicine.

[0033] In summary, the acupuncture needle device with microcurrent stimulation function has achieved the improvement of the effectiveness, safety and patient experience of acupuncture therapy through reasonable structural design and scientific logical analysis, and has provided important support for the modernization of acupuncture technology.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] See also Figures 1 to 4 The present invention relates to an acupuncture needle device with a micro-current stimulation function, which is aimed at a single-handed needle insertion technique, and comprises a positive finger sleeve 1 and a negative finger sleeve 2; the positive finger sleeve 1 is sleeved on the index finger of the operator, and its length makes it sleeve to the base of the finger; the negative finger sleeve 2 is sleeved on the middle finger of the operator, and its length makes it sleeve to the base of the finger; a positive electrode sheet 11 is embedded on the side of the positive finger sleeve 1 close to the thumb; a negative electrode block 21 is embedded at the position corresponding to the fingertip of the negative finger sleeve 2; the positive electrode sheet 11 and the negative electrode block 21 are electrically connected to the positive and negative electrodes of a portable power source respectively; during acupuncture using the single-handed needle insertion technique, the acupuncture needle device forms a current loop between the positive electrode of the portable power source, the acupuncture needle, the acupuncture point, the middle finger touch point and the negative electrode of the portable power source, and performs synchronous current stimulation on the acupuncture points during the acupuncture process.

[0038] In this embodiment, an elastic band 3 is connected to the opposite sides of the positive finger sleeve 1 corresponding to the proximal intersegmental joint of the index finger and the negative finger sleeve 2 corresponding to the proximal phalanx of the middle finger. During the one-handed needle insertion technique, the elastic band 3 is stretched and the restoring force of the elastic band 3 is used to increase the insertion speed of the acupuncture needle.

[0039] In this embodiment, a magnetic guide groove 22 is embedded in the negative electrode finger sleeve 2 corresponding to the middle finger pulp; the diameters of the upper and lower ends of the guide groove 22 are larger than the middle part of this embodiment, forming an expanded groove structure; the guide groove 22 is used to guide and maintain the insertion direction of the acupuncture needle.

[0041] In this embodiment, the main material of the positive electrode finger cover 1 and the negative electrode finger cover 2 is silicone or TPU.

[0042] In this embodiment, the positive electrode sheet 11 is made of a silver-plated polymer or a woven metal material, which has good conductivity and flexibility.

[0043] In this embodiment, the negative electrode block 21 is made of copper or silver-plated material.

[0044] In this embodiment, the elastic band 3 is made of chloroprene rubber or elastic fabric.

[0045] In this embodiment, the guide groove 22 is made of magnetic plastic.

[0046] In this embodiment, the portable power supply is worn at the waist, and the thin conductive wires are respectively connected to the positive electrode sheet 11 and the negative electrode block 21, and then enter the sleeve from the back of the hand, and extend through the arm to the waist to connect the positive and negative electrodes of the portable power supply.

[0047] In this embodiment, the outer surface of the negative electrode block 21 is a curved surface.

[0048] In this embodiment, the voltage of the portable power source can be adjusted manually, and when not adjusted manually, the voltage is automatically kept constant.

[0049] When the acupuncture needle first penetrates the epidermis, the current path consists mainly of the skin's electrical resistance (which is high).

[0050] At this stage, the resistance is relatively high because the skin and superficial tissues have poor electrical conductivity.

[0051] As the acupuncture needle is inserted deeper into tissue, the needle tip comes closer to low-resistance tissue (eg, muscle, blood-rich tissue).

[0052] The deeper tissues are more conductive, so the resistance gradually decreases.

[0053] As the acupuncture needle is inserted deeper, the resistance gradually decreases, causing the current to increase, thereby increasing the stimulation effect of the current in the deep tissue. This current change is automatic and automatically adjusts with different depths, which is in line with the conditioning principles of traditional Chinese medicine acupuncture.
