Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an acupuncture needle insertion device with disinfection function. Background Technology

[0002] Acupuncture, as a treatment method that combines traditional medicine with modern clinical practice, is widely used in medical institutions at all levels. Its operational efficiency, disinfection safety, and cost control directly affect the smoothness of the diagnosis and treatment process and the patient's medical experience. Therefore, there is an urgent need for an integrated device that combines disinfection and needle insertion functions.

[0003] Most existing acupuncture needle insertion devices are manually operated in steps, requiring separate disinfection spraying and manual control of needle insertion timing. The operation time is long and the needle insertion error is easily caused by hand switching or hand tremors. The disinfection process often uses manual press spraying, which makes it difficult to control the amount of alcohol used and it is easy to drip and splash. It may also accidentally spray on clothing or operating table. Residual alcohol can easily irritate the skin and increase the risk of cross-infection. At the same time, there is a lack of operation data recording function, which makes it difficult to meet the hospital's quality control and digital operation needs. In addition, some devices have short battery life and require frequent charging when used at high frequency, increasing operating costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an acupuncture needle insertion device with disinfection function, which solves the problems of low efficiency, poor safety, high cost, and lack of record keeping in existing acupuncture needle insertion devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an acupuncture needle insertion device with disinfection function, comprising a housing, an alcohol storage chamber on the top side of the housing, a residual alcohol adsorption ring at the front end of the housing, a miniature electromagnetic push rod on the inner wall of the housing, an infrared distance sensor on the rear side of the miniature electromagnetic push rod, a needle holder body on the rear side of the infrared distance sensor, a piezoelectric micropump on the rear side of the needle holder body, a solenoid valve on the rear side of the piezoelectric micropump, an MCU board on the rear side of the solenoid valve, a power supply on the rear inner wall of the housing, a capacitive skin sensor on the front side of the miniature electromagnetic push rod, an annular atomizing nozzle on the front side of the capacitive skin sensor, a disposable sterile acupuncture needle at the front end of the needle holder body, and a handle on the bottom rear side of the housing.

[0006] Preferably, the shell is injection molded from medical-grade PC / ABS blend material, and has a cylindrical pen body with a diameter of 15mm and a length of 120mm, with a fine frosted anti-slip texture on the surface; the alcohol storage compartment is a 2mL cartridge-type disposable storage compartment made of food-grade PP material, with a silicone one-way valve on the top, and capacity markings printed on the side wall of the compartment.

[0007] Preferably, the piezoelectric micropump has a rated flow rate of 0.05 mL / cycle, a flow error of ±5%, an operating voltage of 3.3V, a single drive pulse width of 100ms, and a service life of ≥100,000 cycles; the solenoid valve is a 2-way 2-position micro solenoid valve with a diameter of 1.2mm, an opening time of ≤15ms, a closing time of ≤10ms, and a valve body made of PEEK material.

[0008] Preferably, the infrared distance sensor has a detection distance of 0-5mm and a resolution of 0.5mm, and is used to detect the distance between the needle insertion device and the skin; the TOF + capacitive dual sensing achieves anti-mistouch, with a false trigger rate of <0.1%.

[0009] Preferably, the annular atomizing nozzle has six laser micro-holes with a diameter of 0.3 mm evenly distributed around its front circumference. The hole axis is inclined inward at a 30° angle to the center line of the housing, and the spray is in the shape of a hollow cone, which can cover an area with a diameter of 10 mm and a spray angle of 120°. The outer edge of the nozzle is provided with a detachable medical silicone splash shield to adapt to the disinfection needs of complex curved surfaces such as the auricle, between the fingers, and joint folds.

[0010] Preferably, the needle holder body fixes disposable sterile acupuncture needles through a Luer interface. The needle holder body is driven by a miniature electromagnetic push rod with an adjustable stroke of 2-6mm and a step accuracy of 0.1mm. The return spring is made of medical-grade stainless steel with a fatigue life of ≥50,000 cycles. The MCU board is a 32-bit MCU with a main frequency of 48MHz, integrating a 12-bit ADC, Bluetooth 5.0LE protocol stack, low-power RTC, and a standby current of <5μA.

[0011] Preferably, the power supply is a 3.7V 120mAh lithium polymer battery with a Type-C interface at the bottom, supporting 5V / 1A charging. A full charge allows for ≥300 continuous spraying and needle insertions. The MCU has a built-in 3.5V low voltage alarm. The residual alcohol adsorption ring is made of medical-grade porous PVA foam with a thickness of 3mm. It is connected to the front end of the housing via a buckle, has an adsorption capacity of ≥0.05mL, and can be replaced by pressing it out.

[0012] An acupuncture needle insertion control system with disinfection function includes, The user interface module collects and visualizes current operating parameters in real time, including the remaining power of the 3.7V lithium polymer battery, the remaining liquid level of the 2mL cartridge-type alcohol storage tank, and the Bluetooth connection status. It also provides an entry point for acupoint classification selection and supports quick selection of acupoints by region: "head-neck-chest-back-hand-foot". The intelligent needle insertion depth matching module has a built-in database of 93 national standard acupoints. The database pre-stores the clinically recommended needle insertion depth range for each acupoint. When the user selects the target acupoint, the intelligent needle insertion depth matching module automatically calls up the database data and outputs the recommended needle insertion depth to the 32-bit MCU of the acupuncture needle insertion device. It also provides a customizable input interface, allowing users to manually set the needle insertion depth value with a precision of 0.1mm according to clinical needs. The set data is synchronized to the device in real time via Bluetooth. The operation log management module receives data from each uploaded operation via Bluetooth, including timestamps, alcohol spray volume of 0.05 mL / time, and actual needle insertion depth, and stores the most recent 100 operation records in timeline format; it provides log query and export functions, and supports exporting records in CSV format for use in hospital quality control statistics or scientific research data organization.

[0013] Preferably, it also includes a linkage control module. When the infrared distance sensor detects a signal that "the distance to the object is ≤5mm and lasts for more than 50ms", the MCU uploads the trigger signal to the linkage control module via Bluetooth. The module displays a pop-up window on the user interface indicating "Disinfection is starting". After 0.05mL of alcohol spray is completed and the timer is set for 300ms, the MCU uploads a "disinfection complete" signal to the linkage control module. The linkage control module then controls the mobile terminal to emit a beeping sound and displays a "needle insertion ready" indicator on the interface. When the user clicks the "Needle Insertion" button, the MCU uploads the operating status of the electromagnetic push rod to the module. The linkage control module updates the "Needle Insertion Progress" display in real time until the needle holder completes the retraction action. Then, the linkage control module automatically marks this operation as "completed" and updates the log.

[0014] Preferably, it also includes low-power adaptation and anomaly warning functions; Low power consumption adaptation: When the MCU enters STOP mode, the system automatically reduces the Bluetooth connection frequency, switching from real-time communication to status inspection every 10 seconds, reducing power consumption on the mobile terminal side by ≥60%; when the device is woken up, the system synchronously resumes real-time communication mode. Abnormal warning: The system monitors battery voltage data in real time. When the voltage is ≤3.5V, a red "low battery" warning will pop up on the user interface, along with an "estimated number of remaining operations". When the alcohol storage tank is ≤0.2mL, a yellow "low alcohol" warning will pop up on the interface, along with a "Storage tank replacement guide" pop-up window to instruct the user to replace the 2mL cartridge-type alcohol storage tank.

[0015] Operating Principle: The 32-bit MCU is in STOP mode, the LED indicator is off, and the total power consumption is <10μW. Only a 3.7V 120mAh lithium polymer battery provides a small amount of power to ensure battery life. The Type-C interface can be connected to a 5V / 1A power supply for charging at any time. The MCU board has a built-in voltage detection module that triggers a low-voltage alarm when the battery voltage is ≤3.5V. When the operator presses the power button, the MCU is activated, the Bluetooth 5.0 LE protocol stack starts, and it connects to the accompanying Android / iOS mobile terminal's interactive software. The user interface displays the battery level, remaining alcohol storage capacity, and Bluetooth connectivity in real time. The user then holds the handle and aligns the front of the device with the intended acupuncture site, hovering the tip of the disposable sterile acupuncture needle approximately 5mm from the skin. An infrared distance sensor detects that the object is ≤5mm away and remains suspended for more than 50ms. Simultaneously, a capacitive skin sensor confirms that the object is human skin. This TOF + capacitive dual-sensor system controls the false trigger rate to <0.1%, preventing accidental spraying. Upon receiving the dual-sensor confirmation signal, the MCU outputs a 100ms pulse to drive the piezoelectric micro-pump and simultaneously activates a 2-way 2-position micro-solenoid valve. Alcohol in the alcohol storage tank is atomized through an annular nozzle, forming a hollow cone-shaped mist that evenly covers the area. A 10mm diameter area can form a drip-free film even on complex curved surfaces. Residual alcohol adsorption rings absorb unevaporated alcohol, preventing spillage, irritation, or cross-infection. After alcohol spraying, the MCU times the process for 300ms to ensure disinfection effectiveness. After the timer expires, an LED flashes, a buzzer sounds, and the interactive software's control module pops up a "needle insertion ready" message. The operator selects acupoints using the software's intelligent needle depth matching module, which automatically matches a recommended depth of 2-6mm or allows manual customization to a depth of 0.1mm. Data is synchronized to the MCU via Bluetooth. The operator presses the needle insertion button, and the MCU drives the micro-needle... The electromagnetic pusher extends the needle holder body to a preset depth, completing precise acupuncture without contact with the needle body, thus avoiding secondary contamination. 6. After acupuncture, the operator lifts the device, the infrared distance sensor loses its target, the MCU shuts off the electromagnetic pusher, and the needle holder body retracts into the housing under the action of the medical stainless steel return spring. At the same time, the MCU uploads the operation timestamp, 0.05mL spray volume, and actual needle insertion depth to the software via Bluetooth. The operation log management module stores the most recent 100 records in a timeline and supports CSV export. If the alcohol storage tank has a remaining volume of ≤0.2mL, the software will pop up an "Insufficient Alcohol" warning and provide replacement instructions.

[0016] This invention provides an acupuncture needle insertion device with a disinfection function. It has the following beneficial effects: 1. This invention completes the spraying, delay, and needle insertion actions in an integrated manner within 0.4 seconds. Combined with a one-handed grip design, it significantly shortens operation time and reduces needle insertion errors. The 30° angled microporous design forms a uniform film on complex curved surfaces such as the auricle and between the fingers, preventing dripping and splashing. Simultaneously, the TOF + capacitive dual-sensor system controls the false trigger rate to below 0.1%, preventing accidental spraying onto clothing or the operating table. The PVA adsorption ring also recovers residual alcohol, reducing the risk of skin irritation and cross-infection for patients, balancing operational efficiency and safety.

[0017] 2. This invention, with its piezoelectric micro-pump achieving an error margin of ±5%, is far superior to manual press-type sprayers, saving ≥60% of alcohol consumption and significantly reducing hospital operating costs. The 120mAh battery supports ≥300 complete operations, with standby power consumption <10µW, meeting the demands of high-frequency use. Furthermore, the device automatically records the time, dosage, and depth of each operation, providing traceable data for hospital quality control management and research statistics, thus facilitating digital operations.

The device includes an annular atomizing nozzle 7, a disposable sterile acupuncture needle 14 at the front end of the needle holder body 10, a handle 15 at the rear bottom of the housing 1, and the housing 1 is injection molded from medical-grade PC / ABS blend material, with a cylindrical shape of 15mm in diameter and 120mm in length, and a finely frosted anti-slip texture on the surface. The alcohol storage tank 2 is a 2mL cartridge-type disposable storage tank made of food-grade PP material, with a silicone one-way valve on the top and volume markings printed on the side wall. The piezoelectric micropump 3 has a rated flow rate of 0.05mL / cycle, a flow error of ±5%, an operating voltage of 3.3V, a single drive pulse width of 100ms, and a service life ≥100,000 cycles. The solenoid valve 4 is a 2-way 2-position miniature solenoid valve with a diameter of 1.2mm. The valve opening time is ≤15ms, and the valve closing time is ≤10ms. The valve body is made of PEEK material. The infrared distance sensor 5 has a detection distance of 0-5mm and a resolution of 0.5mm, used to detect the distance between the needle insertion device and the skin. Accidental touch prevention is achieved through TOF + capacitive dual sensing, with a false trigger rate of <0.1%. The annular atomizing nozzle 7 has six 0.3mm diameter laser micro-holes evenly distributed around its front circumference. The hole axis is inclined inward at a 30° angle to the center line of the housing, creating a hollow cone-shaped spray that can cover an area with a diameter of 10mm and a spray angle of 120°. The outer edge of the nozzle is equipped with a detachable medical silicone splash guard to accommodate the disinfection needs of complex curved surfaces such as the auricle, finger gaps, and joint folds. The needle holder body 10 fixes the disposable sterile acupuncture needle 14 through a Luer interface. The base body 10 is driven by a miniature electromagnetic push rod 9, with an adjustable stroke of 2-6mm and a step accuracy of 0.1mm. The return spring is made of medical-grade stainless steel with a fatigue life of ≥50,000 cycles. The MCU board 11 is a 32-bit MCU with a main frequency of 48MHz, integrating a 12-bit ADC, Bluetooth 5.0LE protocol stack, and low-power RTC, with a standby current of <5μA. The power supply 12 is a 3.7V 120mAh lithium polymer battery with a Type-C interface 13 at the bottom, supporting 5V / 1A charging. A full charge allows for ≥300 continuous spraying and needle insertions. The MCU has a built-in 3.5V low voltage alarm. The residual alcohol adsorption ring 8 is made of medical-grade porous PVA foam with a thickness of 3mm, connected to the front end of the housing 1 via a snap-fit, and has an adsorption capacity of ≥0.0.5mL, press to pop out for replacement; Specifically, before clinical acupuncture, the operator first holds the device through the handle 15 on the bottom rear of the housing 1, checks the remaining power of the power supply 12 and the remaining liquid in the alcohol storage tank 2 displayed on the user interface module, and after confirming that the Bluetooth connection is normal, selects the "head-neck-chest-back-hand-foot" area to which the target acupoint belongs. The intelligent needle depth matching module automatically calls the recommended needle depth (2-6mm adjustable) of the corresponding acupoint from the built-in database of 93 national standard acupoints. If adjustment is required, the needle depth value with a precision of 0.1mm can be set through the custom input interface. The data is synchronized to the device via the Bluetooth 5.0LE protocol stack of the MCU board 11. Subsequently, the operator aligns the front end of the housing 1 with the intended acupuncture site, suspending the tip of the disposable sterile acupuncture needle 14 at approximately 5mm from the skin. At this point, the infrared distance sensor 5 detects a signal indicating that the object is ≤5mm away and remains so for more than 50ms. Simultaneously, the capacitive skin sensor 6 assists in confirming that the object in contact is human skin. Through TOF + capacitive dual sensing, the false trigger rate is controlled to <0.1%, preventing accidental spraying. After receiving the dual sensor confirmation signal, the MCU board 11 outputs a 100ms pulse to drive the piezoelectric... Micropump 3 simultaneously opens a 2-way 2-position micro solenoid valve 4. The alcohol in the alcohol storage tank 2 is atomized by an annular atomizing nozzle 7 (with 6 laser micro-holes of 0.3mm diameter evenly distributed around the front circumference, and the hole axis is inclined inward at 30° with the center line of the shell) to form a hollow cone-shaped mist screen, which evenly covers an area with a diameter of 10mm. The detachable medical silicone splash shield on the outer edge of the nozzle can adapt to the disinfection needs of complex curved surfaces such as the auricle and between the fingers. The residual alcohol adsorption ring 8 (medical-grade porous PVA foam, 3mm thick) adsorbs the unevaporated alcohol to prevent spillage, irritation, or cross-infection.

[0022] Please see the appendix Figure 1 and attached Figure 2 An acupuncture needle insertion control system with disinfection function includes, The user interface module collects and visualizes the current operating parameters in real time, including the remaining power of the 3.7V lithium polymer battery, the remaining liquid level of the 2mL cartridge-type alcohol storage tank 2, and the Bluetooth connection status.

Abnormal warning: The system monitors battery voltage data in real time. When the voltage is ≤3.5V, a red "low power" warning will pop up on the user interface, and "estimated remaining number of operations" will be displayed. When the alcohol storage tank is ≤0.2mL, a yellow "low alcohol" warning will pop up on the interface, and a "storage tank replacement guide" pop-up window will be provided to guide the user to replace the 2mL cartridge-type alcohol storage tank. Specifically, after the alcohol spraying is completed (0.05mL per spray, meeting the rated flow rate of the piezoelectric micropump 3), the MCU board 11 times the timer for 300ms to ensure the disinfection effect. After the timer expires, the linkage control module controls the mobile terminal to emit a buzzer prompt, and the interface displays the "Needle insertion can proceed" indicator, while the LED flashes as a reminder. The operator presses the needle insertion button, and the MCU board 11 drives the micro electromagnetic push rod 9 to push the needle holder body 10 out to the preset depth. The needle holder body 10 is fixed to the disposable sterile acupuncture needle 14 through the Luer interface. The micro electromagnetic push rod 9 has a stepping accuracy of 0.1mm, ensuring the accuracy of acupuncture, and the entire process does not require contact with the needle body, avoiding secondary contamination. After the acupuncture is completed, the operator lifts the device, the infrared distance sensor 5 loses the target signal, the MCU board 11 shuts down the miniature electromagnetic push rod 9, and the needle holder body 10 retracts into the housing 1 under the action of the medical stainless steel return spring (fatigue life ≥50,000 times). At the same time, the MCU board 11 uploads the timestamp of this operation, the 0.05mL alcohol spray volume, and the actual needle insertion depth to the operation log management module via Bluetooth. The module stores this record in timeline format (it can store the most recent 100 records) and supports subsequent export in CSV format for hospital quality control statistics. If the voltage of the power supply 12 (3.7V 120mAh lithium polymer battery) is ≤3.5V during the process, a red "low battery" warning pops up on the interface and indicates the remaining number of operations; if the remaining alcohol in the alcohol storage tank 2 is ≤0.2mL, a yellow "low alcohol" warning pops up on the interface and provides instructions for replacing the storage tank. The operator can press the buckle structure to pop out the residual alcohol adsorption ring 8 for replacement, and at the same time replace the 2mL cartridge-type alcohol storage tank 2.

Then, the linkage control module automatically marks this operation as "completed" and updates the log.

10. An acupuncture needle insertion device with disinfection function according to claim 1, characterized in that, It also includes low-power adaptation and anomaly warning functions; Low power consumption adaptation: When the MCU enters STOP mode, the system automatically reduces the Bluetooth connection frequency, switching from real-time communication to status inspection every 10 seconds, reducing power consumption on the mobile terminal side by ≥60%; when the device is woken up, the system synchronously resumes real-time communication mode. Abnormal warning: The system monitors battery voltage data in real time. When the voltage is ≤3.5V, a red "low battery" warning will pop up on the user interface, along with an "estimated number of remaining operations" message. When the alcohol storage tank is ≤0.2mL, a yellow "low alcohol" warning will pop up on the interface, along with a "Storage tank replacement guide" pop-up window to instruct the user to replace the 2mL cartridge-type alcohol storage tank.
