Abstract
Description
Technical Field
[0001] This invention relates to the field of traditional Chinese medicine acupuncture equipment technology, specifically to a multifunctional acupuncture needle. Background Technology
[0002] Traditional Chinese medicine acupuncture is a therapy guided by TCM theory. It involves inserting specially made metal needles into specific acupoints on the human body (needling) or using the heat generated by burning materials such as moxa wool to fumigate and warm acupoints (moxibustion). This stimulates the meridians and acupoints to unblock the meridians, harmonize qi and blood, balance yin and yang, and strengthen the body's resistance to disease and eliminate pathogens. As a result, it is a traditional Chinese medicine therapy that can prevent and treat diseases and regulate bodily functions. It is an important part of TCM, with a unique theoretical system and rich clinical experience, and is widely used in the prevention, treatment, and health maintenance of various diseases.
[0003] Traditional Chinese medicine acupressure therapy stimulates the meridians to activate the body's self-healing abilities. Acupressure can harmonize Qi and blood, relieve pain (such as headaches and muscle aches), and regulate organ function (such as promoting digestion and improving sleep). It is convenient, immediate, non-invasive, and safe. However, relying solely on hand pressure results in a large application area, making it difficult to accurately target acupoints and affecting the efficiency of Qi conduction. It also has insufficient penetration into deep acupoints or dense tissues (such as the lumbosacral region). To address this issue, the existing Yunlong brand YL-09 needle consists of three parts: a needle head, a needle handle, and a needle tail, which gradually thicken. The needle head is designed with a hemispherical, slightly convex curved surface. By aligning the needle head with the acupoint to be pressed and applying pressure to the needle tail, the acupoint can be accurately pressed, thereby improving the therapeutic effect.
[0004] In practice, although the acupressure can accurately press the acupoints, the low ambient temperature in winter can cause poor blood circulation at the acupoints when in contact with the skin, affecting the therapeutic effect of warming the meridians and promoting blood circulation, reducing the effect of acupressure on pain relief and meridian unblocking, and thus reducing the effectiveness of acupressure therapy.
[0005] Therefore, the present invention proposes a multifunctional needle to solve the above problems. Summary of the Invention
[0006] To address the aforementioned problems, this invention provides a multifunctional moxibustion needle that utilizes the medicinal properties of mugwort and controls the needle tip temperature through telescopic and heat dissipation components to improve therapeutic efficacy.
[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A multifunctional needle includes a syringe, a handle detachably connected to the top of the syringe, a needle fixedly connected to the bottom of the syringe, a first spring fixedly connected to the top of the handle, a push rod fixedly connected to the bottom of the first spring, a pressure ring fixedly connected to the middle of the push rod, a cap fixedly connected to the bottom of the push rod, an moxa stick detachably connected inside the cap, first toothed racks fixedly connected to both sides of the cap, a ring fixedly connected to the inner wall of the needle, symmetrically arranged connecting rods fixedly connected to the top of the ring, second toothed racks fixedly connected to the inner sides of the connecting rods respectively, and the second toothed racks respectively meshing with the corresponding first toothed racks, and support rods slidably fitted to the outer walls of the connecting rods, with the other ends of the support rods respectively... The needle is fixedly connected to the inner wall of the syringe. The syringe contains a telescopic component to assist the extension and retraction of the moxa stick. The middle of the syringe contains a heat dissipation component for ventilation at high temperatures. The moxa stick is lit and the handle is installed on the top of the syringe. The handle is held and pressed down to make the needle press the acupoint. The pressure on the needle causes the ring to move upward, which in turn causes the second rack to move upward. Through the meshing of the first rack and the second rack, the push rod, pressure ring, cap and moxa stick are moved vertically downward, bringing the moxa stick closer to the needle. At this time, the pressure ring applies pressure to the telescopic component to compress it. When the handle is released, the pressure on the push rod disappears, and the rebound force of the telescopic component causes the push rod, pressure ring, cap and moxa stick to move vertically upward and reset, moving the moxa stick away from the needle.
[0008] The technical principle of the above scheme is as follows: When the acupoint is pressed by pressing the handle, the needle is pressed and the ring moves upward, which in turn moves the connecting rod and the second rack upward. Through the meshing of the first rack and the second rack, the push rod, pressure ring, cap and moxa stick move vertically downward, so that the moxa stick is close to the needle. At this time, the pressure ring compresses the telescopic component to store energy. After releasing, the telescopic component rebounds and pushes the pressure ring upward. The pressure ring drives the push rod to move upward to reset, and at the same time the moxa stick moves away from the needle.
[0009] The above-mentioned solution has the following beneficial effects: Compared with the existing technology, this solution uses the heat of burning moxa sticks and acupressure at the same time, which avoids the obstruction of qi and blood caused by low needle temperature, improves the efficacy of warming the meridians and promoting blood circulation, and prevents burns through the automatic reset structure.
[0010] Furthermore, the telescopic assembly includes a fixed ring, the outer wall of which is fixedly connected to the inner wall of the syringe, a second spring is fixedly connected to the top of the fixed ring, a support ring is fixedly connected to the top of the second spring, and the support ring slides with the inner wall of the syringe. When the support plate is not compressed, the top wall of the support ring and the top wall of the syringe are on the same horizontal plane, and the top wall of the support ring is in contact with the bottom wall of the pressure ring.
[0011] Beneficial effects: The pressure ring moves vertically downward to apply pressure to the support ring, which in turn compresses and stores energy in the second spring. After the pressure ring is released, the second spring rebounds and pushes the support ring back to its original position. At the same time, the sliding cooperation between the support ring and the inner wall of the syringe ensures the vertical movement of the moxa stick and prevents the moxa from shifting.
[0012] Furthermore, the heat dissipation component includes several vent holes, all of which are located on the middle side wall of the syringe. Several metal plates corresponding to the vent holes are fixedly connected to the outer wall of the middle part of the syringe, and the metal plates are fixedly connected to the syringe through both sides.
[0013] Beneficial effect: The metal sheet covering the vent hole helps to keep the syringe warm.
[0014] Furthermore, a pressure sensor is embedded in the bottom of the needle, and the pressure sensor signal is connected to a controller. The controller signal is connected to a warning light and a display screen, and both the warning light and the display screen are fixedly connected to the outer wall of the syringe.
[0015] Beneficial effects: The pressure sensor monitors the pressing force in real time, and the controller analyzes the pressure data. The pressure value is then fed back through warning lights and a display screen, preventing excessive pressing force from damaging deep tissues.
[0016] Furthermore, a silicone layer is fixedly connected to the inner wall of the cap.
[0017] Beneficial effects: The silicone layer increases the friction between the cap and the moxa stick, aiding in fixation and ensuring the stability of the moxa stick during movement, while also achieving elastic clamping.
[0018] Furthermore, the bottom sidewall of the handle has anti-slip texture.
[0019] Beneficial effect: The anti-slip texture increases the roughness of the handle surface, preventing it from slipping off due to wet hands during operation.
[0020] Furthermore, the needle tip has several ventilation holes.
[0021] Beneficial effects: The ventilation holes allow airflow inside and outside the syringe to pass through, while also facilitating the application of moxa smoke to acupoints.
[0022] Furthermore, the handle is made of heat-insulating resin.
[0023] Beneficial effects: The heat-insulating resin material blocks heat transfer to the handle, protecting the operator's hands while preventing ineffective heat loss.
[0024] Furthermore, the metal sheets are all made of bimetal, with the inner side of the metal sheets being made of iron and the outer side being made of copper.
[0025] Beneficial effects: At room temperature, the metal sheet covers the exhaust vent for heat preservation. At high temperatures, because the expansion coefficient of copper is higher than that of iron, copper expands more. The metal sheet bends inward, opening the exhaust vent and allowing cold air to enter for cooling.
[0026] Furthermore, the needle tip has a hemispherical convex curved surface structure.
[0027] Beneficial effects: The hemispherical convex surface fits the surface of the acupoint, while avoiding scratching the skin.
[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0036] The following detailed description illustrates the specific implementation method:
[0037] Example 1:
[0038] As attached Figure 1 As shown: A multifunctional acupuncture needle includes a syringe 1, with a handle 2 detachably connected to the top of the syringe 1. The bottom side wall of the handle 2 has anti-slip texture to prevent the handle 2 from falling off when the hands are wet. A needle 3 is welded to the bottom of the syringe 1. The needle 3 has a hemispherical convex curved surface structure, which allows the needle 3 to accurately press acupoints without scratching the skin. Since low-temperature acupressure can cause poor blood circulation at the acupoints, significantly reducing the therapeutic effect, heating is provided during acupressure to ensure blood flow at the acupoint. (See attached image) Figure 2As shown, a first spring 13 is fixedly connected to the top of the handle 2 by adhesive. A push rod 4 is welded to the bottom of the first spring 13. The other end of the push rod 4 extends into the syringe 1. A pressure ring 5 is welded to the middle of the push rod 4. A cap 6 is welded to the bottom of the push rod 4. An moxa stick 7 is detachably connected inside the cap 6. First toothed racks 21 are welded to both sides of the cap 6. A ring 18 is fixedly connected to the inner wall of the needle 3 by adhesive. A symmetrically arranged connecting rod 19 is welded to the top of the ring 18. Second toothed racks 20 are welded to the inner side of the connecting rods 19, and the second toothed racks 20 respectively mesh with the corresponding first toothed racks 21. Support rods 22 are slidably fitted to the outer wall of the connecting rods 19. The other end of the support rods 22 is fixedly connected to the inner wall of the syringe 1. The support rods 22 restrict the connecting rods 19 to slide in a vertical plane. To prevent heat loss through the handle 2, which is made of heat-insulating resin, and to ensure the moxa stick 7 is securely fixed, the inner wall of the cap 6 is glued with a silicone layer 16. The syringe 1 is equipped with a telescopic component to assist the extension and retraction of the moxa stick 7. The telescopic component includes a fixing ring 8, the outer wall of the fixing ring 8 is welded to the inner wall of the syringe 1, a second spring 9 is welded to the top of the fixing ring 8, and a support ring 10 is welded to the top of the second spring 9. The support ring 10 slides with the inner wall of the syringe 1. When the support ring 10 is not compressed, the top wall of the support ring 10 is on the same horizontal plane as the top wall of the syringe 1, and the top wall of the support ring 10 is in contact with the bottom wall of the pressure ring 5. The needle 3 has several vent holes 17 so that the smoke from the combustion of the groove can act on the acupoint through the vent holes 17.
[0039] Because the continuous burning of the moxa stick 7 may cause the internal temperature of the syringe 1 to rise continuously, potentially causing burns to the patient's skin, to avoid excessively high temperatures in the syringe 1, as shown in the attached... Figure 2 As shown, the syringe 1 has a heat dissipation component in the middle for ventilation at high temperatures. The heat dissipation component includes several vent holes 11. Several metal plates 12 corresponding to the vent holes 11 are welded to the outer wall of the middle part of the syringe 1. The metal plates 12 are all welded to the syringe 1 through both sides. The metal plates 12 are all made of bimetal, with the inner side of the metal plate 12 being made of iron and the outer side being made of copper. Since the coefficient of thermal expansion of copper is significantly higher than that of iron, the expansion of copper is greater when the temperature rises, forcing the metal plates 12 to bend towards the iron layer. At room temperature, the metal plates 12 are flat and cover and close the vent holes. When the temperature is higher than 55°C, the metal plates 12 are heated and bend towards the iron layer. The bending of the metal plates 12 creates openings on both sides, allowing the vent holes 11 to communicate with the outside. At this time, the vent holes open, and cold air enters the syringe 1 for cooling. When the temperature drops below 45°C, both the copper layer and the iron layer contract and return to their original position, causing the metal plates 12 to return to their flat position and re-close the vent holes to keep the syringe 1 warm.
[0040] The specific implementation process is as follows: Before pressing the acupoints for the patient, first, install the lit moxa stick 7 inside the cap 6, then install the handle 2 onto the syringe 1. After installation, hold the handle 2 and press down, simultaneously driving the needle 3 to press the acupoints. The downward pressing of the needle 3 drives the ring 18 to move upward, and the ring 18 drives the connecting rod 19 and the second rack 20 to move upward simultaneously. Through the meshing of the first rack 21 and the second rack 20, the cap 6 moves downward, simultaneously driving the moxa stick, the push rod 4, and the pressure... The force ring 5 moves downward, bringing the moxa stick 7 closer to the needle 3. This increases the temperature at the needle 3 while the moxa smoke acts on the acupoint skin through the vent hole 17. By pushing the moxa stick 7 closer to the vent hole 17, it not only facilitates the moxa smoke passing through the vent hole 17 to act on the skin, but also pushes the moxa smoke in the syringe 1 to the needle 3, improving the therapeutic effect and utilization rate of the moxa. The pressure ring 5 applies pressure to the support ring 10 and the second spring 9, causing the second spring 9 to compress and store energy.
[0041] When the mugwort continues to burn and the temperature inside the syringe 1 exceeds 55°C, the metal plate 12 bends to open the exhaust port, allowing cold air to enter the syringe 1 for cooling. When the temperature drops below 45°C, the metal plate 12 contracts and straightens, resealing the exhaust port, and the eczema tube enters a heat preservation state. Through the cooperation of the metal plate 12 and the exhaust port, the temperature inside the syringe 1 is maintained between 45°C and 55°C, ensuring that the blood at the acupoints can flow normally while preventing the patient from being burned due to excessively high temperature.
[0042] When the acupoint pressing is completed and the acupoint pressing needs to be changed, the pressing force of the handle 2 is released, which releases the pressure on the needle 3 and the ring 18. At this time, the stored energy of the compressed second spring 9 is released, and the elastic force of the second spring 9 drives the support ring 10 to rebound. At the same time, the support ring 10 pushes the pressure ring 5 upward, which in turn drives the push rod 4 and the cap 6 to reset. The moxa stick 7 gradually moves away from the needle 3.
[0043] By applying pressure to the acupoint by holding the handle 2, the pressure ring 5, cap 6, and moxa stick 7 are simultaneously pushed downwards, causing the moxa stick 7 to actively approach the needle tip 3. The heat from the burning moxa stick 7 eliminates local blood and qi stagnation caused by the low temperature of the metal. At the same time, the moxa smoke penetrates the acupoint through the vent 17 of the needle tip 3, enhancing the efficacy of the medicine. Meanwhile, the pressure ring 5 compresses the second spring 9 to store energy, and the support ring 10 moves vertically downwards along the inner wall of the syringe 1 to ensure the stability of the operation. When the moxa stick 7 continues to burn and the temperature inside the syringe 1 exceeds 55°C, the copper-iron composite metal sheet 12 bends inwards due to the higher expansion rate of the copper layer, automatically opening. Cool air is introduced through the vent 11 to lower the temperature. Once the temperature drops below 45°C, the metal plate 12 contracts and resets to seal the vent 11, maintaining a constant temperature treatment range of 45–55°C within the syringe 1. This avoids burns while ensuring continuous warming and unblocking of the meridians. After releasing the pressure, the second spring 9 releases its stored energy, pushing the support ring 10 upwards to reset. This causes the pressure ring 5, push rod 4, and moxa stick 7 to move upwards and away from the needle 3, blocking residual heat transfer and preventing burns, thus completing one pressing cycle. The entire process achieves a closed-loop treatment with simultaneous heating during pressing and automatic separation upon release, significantly enhancing the efficacy of warming and unblocking the meridians.
[0044] The multifunctional needle from Example 1 was compared with the traditional Yunlong brand YL-09 needle. The specific experiment is as follows:
[0045] Experimental objective:
[0046] Thermal effect maintenance capability: Test the temperature stability of the needle and its impact on blood flow at acupoints;
[0047] Treatment efficacy: Comparison of the immediate effects of warming the meridians and relieving pain;
[0048] Safety: Evaluate the scald prevention performance of the automatic temperature control system and the safety of the press-to-reset mechanism.
[0049] Experimental steps:
[0050] 1. Equipment Preparation
[0051] Experimental group: Assemble the multifunctional needle (syringe + handle + moxa stick + bimetallic heat dissipation assembly) of Example 1.
[0052] Control group: Yunlong brand YL-09 needle (hemispherical convex needle head, no heating function).
[0053] Auxiliary tools: Infrared thermal imager (for measuring needle temperature); Laser Doppler flowmeter (for monitoring microcirculation blood flow velocity at acupoints); Pressure sensor pad (calibrated to a pressure of 0.5±0.1 kg / cm²). 2 Pain rating scale (VAS visual analog scale, 0-10 points)
[0054] 2. Experimental Procedure
[0055] Temperature control test:
[0056] Light the multi-functional moxa stick and fix it on the stand, with the needle tip suspended in the air.
[0057] The temperature change of the needle tip was continuously recorded over 30 minutes using a thermal imager, and the deformation of the bimetallic strip at 55℃ and the opening and closing status of the vent were observed.
[0058] The control group was placed under the same conditions, and the temperature of the metal needle at room temperature was recorded.
[0059] Comparison of acupoint therapy:
[0060] Thirty volunteers with lumbar muscle strain were recruited and randomly divided into two groups. Each group underwent testing at the bilateral Zusanli acupoints.
[0061] Group A: Press the left side with a traditional moxa needle for 3 minutes; press the right side with a multi-functional moxa needle (without burning the moxa stick) for 3 minutes.
[0062] Group B: Press the left side with a traditional moxa needle for 3 minutes; press the right side with a multi-functional moxa needle (with a lit moxa stick) for 3 minutes.
[0063] Measure the blood flow velocity at the acupoint before and after each press, and record the pain score immediately after pressing.
[0064] Security verification:
[0065] Continuously heat the multi-functional needle until the temperature inside the syringe reaches 60°C, and observe the response time of the heat dissipation component and the temperature drop curve.
[0066] Test the speed at which the moxa stick returns to its original position after being released (high-speed photography records displacement time).

[0072] 3. Security
[0073] To prevent burns: When the temperature inside the syringe reaches 58°C, the metal plate opens the vent within 8 seconds and cools down to 51°C within 12 seconds.
[0074] Reset performance: After releasing the hand, the second spring pushes the moxa stick up 5mm within 0.3±0.05 seconds, and the needle temperature drops 8℃ within 10 seconds.
[0075] Experimental conclusion:
[0076] Significantly enhanced by heat therapy: The multifunctional acupuncture needle is heated by moxa sticks to stabilize the needle tip at 45-55℃ (traditional acupuncture needles only require room temperature), increasing the blood flow speed at acupoints to 3 times that of traditional needles, and improving pain relief by 127%, confirming its synergistic effect of "warming the meridians and promoting blood circulation".
[0077] Intelligent temperature control reliability: The bimetallic heat dissipation component is precisely triggered at 54-55℃, keeping the syringe temperature fluctuation within 10℃ to avoid the risk of burns (traditional needles do not have this risk but do not provide heat therapy benefits).
[0078] Effective safety reset mechanism: The second spring reset system ensures that the moxa stick moves away from the needle instantly after release (displacement response time ≤ 0.3 seconds), eliminating the risk of burns from residual heat.
[0079] Example 2:
[0080] As attached Figure 2 As shown, the difference from Example 1 is that since acupressure relies entirely on the experience of traditional Chinese medicine practitioners, uneven pressure or excessive pressure can easily lead to damage to deep tissues. In order to monitor the pressure in real time and make adjustments accordingly to achieve better therapeutic effects, a pressure sensor 13 is embedded in the bottom of the needle 3. The preferred model of the pressure sensor 13 is Honeywell FSS005WNG. The pressure sensor 13 is connected to a controller, which is preferably STMicroelectronics STM32F030K6T6. The controller is connected to an alarm light 14 and a display screen 15. The preferred model of the alarm light 14 is OSRAM SFH 4715AS. The preferred model of the display screen 15 is SOLOMON SYSTECH SSD1306 driver chip + 0.96" OLED. Both the alarm light 14 and the display screen 15 are fixedly connected to the outer wall of the syringe 1.
[0081] The specific implementation process is as follows: After the operator lights the moxa stick 7 and installs the handle 2 on the top of the syringe 1, they hold the handle 2 and press the acupoint. At this time, the pressure sensor 13 embedded in the bottom of the needle 3 monitors the pressure data in real time and transmits the data to the controller. The controller analyzes and processes the pressure data. On the one hand, it displays the real-time pressure value on the display screen 15 on the outer wall of the syringe 1 for the operator's reference. On the other hand, it compares the pressure with the preset safety threshold. If the pressure exceeds the threshold, the warning light 14 is immediately triggered to emit a red light alarm, prompting the operator to reduce the pressure to avoid damaging deep tissues. The operator dynamically adjusts the pressure according to the pressure value feedback on the display screen 15 and the status of the warning light 14 to achieve precise and controllable acupoint stimulation.
[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
