Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a painless meridian needle with multi-angle adjustable insertion based on traditional Chinese medicine meridians. Background Technology

[0002] The meridian theory in Traditional Chinese Medicine (TCM) is an important component of TCM theory. It posits the existence of invisible energy channels within the human body—the meridians. These meridians connect the various internal organs and limbs, responsible for circulating qi and blood, harmonizing yin and yang, and nourishing the entire body. The tendon meridians are a type of meridian system, primarily related to muscles, fascia, and other soft tissues, responsible for maintaining the body's motor functions and postural stability.

[0003] In the mid-1990s, Professor Dong Fuhui and other experts from the China Academy of Traditional Chinese Medicine, after long-term clinical and scientific research practice, proposed a new disease name and diagnostic criteria for cutaneous nerve entrapment syndrome. They discovered that many pains and discomforts without obvious causes, such as chronic soft tissue injuries and myofascitis, are actually caused by nerve dysfunction due to entrapment of cutaneous nerves during their course.

[0004] Based on the discovery of cutaneous nerve entrapment syndrome, Professor Dong Fuhui and other experts began to explore the potential of ancient beryllium needle therapy and, combined with modern medical technology and materials, developed modern beryllium needles. Modern beryllium needles are made of titanium alloy and have the advantages of small incisions, less pain, no need for anesthesia, accurate positioning, and more thorough release. They can reduce intrafascial pressure by cutting subcutaneous tissue and fascia, releasing adhesions, thereby eliminating tension stimulation and compression on sensory nerve endings and relieving pain.

[0005] In existing technologies, the practical application of beryllium needles often requires doctors to possess extensive experience and refined skills to ensure the accuracy and safety of treatment. Therefore, the promotion and application of this technology are somewhat limited. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a multi-angle adjustable painless meridian beryllium needle based on traditional Chinese medicine meridians. This reduces the difficulty of beryllium needle operation, automates needle insertion, improves the safety of beryllium needle technique, and reduces the time consumed during beryllium needle treatment.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A multi-angle adjustable painless meridian needle based on traditional Chinese medicine meridians, comprising a cannula, a needle body inside the cannula, the cannula being used to limit the insertion angle of the needle body, the needle body including a needle handle, a needle blade on the needle handle, an adjustment component on the needle handle, the adjustment component being used to adjust the angle between the axis of the needle handle and the axis of the needle blade, a driving component on the cannula, the driving component being used to change the air pressure inside the cannula to drive the needle body to move, a testing component at the output end of the cannula, the testing component being used to obtain the angular relationship between the needle body and the skin section at the insertion position, and several suction cups fixedly connected to the outer periphery of the bottom of the cannula, the bottom wall edge of the suction cups being covered with a skin-friendly adhesive layer;

[0008] It also includes a control system, which is used to determine whether the sleeve has reached the needle insertion position based on the change of air pressure in the sleeve, to determine the needle insertion displacement based on the change of magnetic field of the beryllium needle body, and to determine the angle relationship between the tangent plane of the needle insertion position and the axis of the needle blade based on the change of air pressure. Based on the angle relationship, it controls the adjustment component to work, and controls the drive component to work when the needle blade is adjusted to be perpendicular to the tangent plane of the needle insertion position.

[0009] Furthermore, the needle handle includes a fixed end, and a rotating end is ball-jointed to one end of the fixed end near the needle blade. The rotating end is fixedly connected to the needle blade. The adjustment component includes a first electromagnet, and a permanent magnet is provided inside the rotating end. The first electromagnet is used to drive the permanent magnet to move, and the permanent magnet is used to drive the rotating end to rotate. The control system controls the first electromagnet to work according to the angle relationship.

[0010] Furthermore, the drive assembly includes an adjusting plate with a fixing ring for fixing the fixed end. The adjusting plate is fixedly connected to the inner wall of the sleeve, and the adjusting plate divides the sleeve into a drive chamber and an adjusting chamber containing a rotating end. The drive chamber is connected to the pump assembly. The adjusting plate has several holes, and several elastic baffles are glued and fixed to the walls of the holes. A second electromagnet is fixedly connected to the side wall of each baffle. The second electromagnet is used to close the holes. The control system controls the operation of the pump assembly and the second solenoid valve according to the angle relationship.

[0011] Furthermore, the control system includes a barometric pressure sensor, a magnetostrictive displacement sensor, and a controller;

[0012] The pressure sensor is used to collect air pressure information inside the drive chamber;

[0013] The magnetostrictive displacement sensor is used to collect the needle insertion displacement information of the beryllium needle body. The magnetostrictive displacement sensor is fixedly connected to the bottom wall of the adjustment disk.

[0014] The controller is used to determine whether the cannula has reached the needle insertion position based on the air pressure information, and after the cannula is in place, it obtains the angular relationship between the tangent plane of the needle insertion position and the axis of the needle blade. It reads the needle insertion displacement information of the beryllium needle body based on the change of the permanent magnet magnetic field, controls the first electromagnet to work based on the angular relationship, and controls the pump assembly and the second electromagnet to work when the needle blade is adjusted to be perpendicular to the tangent plane of the needle insertion position.

[0015] Furthermore, the drive chamber is also equipped with a pressure accumulator, the pump assembly is connected to the pressure accumulator, and solenoid valves are provided at the connection points between the pressure accumulator and the drive chamber and the pump assembly. The pressure accumulator is connected to the drive chamber, and a pressure relief valve is provided at the connection point between the pressure accumulator and the drive chamber.

[0016] Furthermore, an electric heating wire is provided inside the drive cavity to heat the gas inside the drive cavity.

[0017] Furthermore, the control system also includes a temperature sensor, which is used to collect temperature information of the needle blade, and the controller controls the operation of the heating wire based on the temperature information.

[0018] Furthermore, the testing component includes a test ring, which is fixedly connected to the output end of the sleeve. The test ring is made of elastic material and has several strain gauges evenly arranged on it. The strain gauges are used to collect the strain information of the test ring. The controller determines the angle between the plane of the sleeve output end and the cut surface of the needle insertion skin based on the strain information, and controls the first electromagnet to work based on the angle between the plane of the sleeve output end and the cut surface of the needle insertion skin.

[0019] Furthermore, it also includes an alarm component, which is used to alert the user. The controller determines whether the cannula output end is in contact with and fully adheres to the patient's skin based on air pressure and strain information. If the cannula output end does not fully adhere to the patient's skin within a set time after contacting the patient's skin, the controller controls the alarm component to alert the user.

[0020] Furthermore, the controller is also used to control the alarm component to send an alarm to the user after the temperature information reaches the set temperature.

[0021] Furthermore, the controller is also used to detect changes in strain information, determine whether the beryllium needle body has been successfully inserted, and only control the alarm component to send an alarm to the user after successful insertion.

[0022] Furthermore, the regulating cavity is equipped with several elastic material partitions, which are evenly arranged.

[0023] The technical principles and beneficial effects of the above scheme are as follows:

[0024] In this solution, the angle of the beryllium needle is adjusted according to the angle between the beryllium needle and the patient's skin by using the adjustment component and the drive component together. This ensures that the position of the beryllium needle edge is always roughly perpendicular to the patient's skin before insertion, thereby reducing the pain during the insertion process. At the same time, this solution uses pressure accumulation to quickly push the beryllium needle into the patient's skin, further reducing the pain during the insertion process.

[0025] Compared to existing technologies, this solution reduces the number of steps required for needle insertion, simplifies the acupuncture process, and lowers the professional skill requirements for acupuncture practitioners, thus promoting the widespread application of beryllium needle technology. Furthermore, the adjustable disc design in this solution makes needle installation convenient and quick, helping to reduce patient anxiety during acupuncture preparation and thereby lessening patient resistance. The adjustable disc and other design features also prevent residual disinfectant on the beryllium needle from entering electrical components such as the pump assembly, thereby extending the lifespan of the device.

[0026] 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

[0038] The following detailed description illustrates the specific implementation method:

[0039] Example 1:

[0040] As attached Figure 1 - Appendix Figure 7As shown: A multi-angle adjustable painless meridian needle based on traditional Chinese medicine meridians includes a sleeve 1, inside which is a needle body 2. The sleeve 1 is used to limit the insertion angle of the needle body 2. The needle body 2 includes a needle handle with a needle blade 21. The needle handle includes a fixed end 23. The size of the fixed end 23 away from the needle blade 21 is slightly larger than the other parts. The fixed end 23 near the needle blade 21 is ball-hinged with a rotating end 22. The rotating end 22 is bonded and fixed to the needle blade 21. The needle handle is also provided with an adjustment component 3. The adjustment component 3 is used to adjust the angle between the axis of the needle handle and the axis of the needle blade 21. The adjustment component 3 includes a first electromagnet 32, and a permanent magnet 31 is embedded in the rotating end 22. The first electromagnet 32 ​​is used to guide the movement of the permanent magnet 31, and the permanent magnet 31 is used to drive the rotating end 22 to rotate.

[0041] The sleeve 1 is provided with a driving component 4, which is used to change the air pressure inside the sleeve 1 to drive the beryllium needle body 2 to move. The driving component 4 includes an adjusting plate 41. A retaining ring 44 of elastic material is bonded and fixed at the axial position of the adjusting plate 41. The retaining ring 44 is used to fix the fixed end 23. The adjusting plate 41 is bonded and fixed to the inner side wall of the sleeve 1. The adjusting plate divides the sleeve 1 into a driving cavity 5 and an adjusting cavity 7 containing a rotating end 22. The driving cavity 5 is connected to a pump component 42. In this embodiment, the pump component 42 is a miniature air pump. The adjusting plate 41 has several holes, and several baffles of elastic material are bonded and fixed to the walls of the holes. The elastic modulus of the baffles is much smaller than that of the retaining ring 44. A second electromagnet 43 is bonded and fixed to the side wall of the baffles. The second electromagnet 43 is used to close the holes.

[0042] The testing component is used to obtain the angular relationship between the beryllium needle body 2 and the skin section at the needle insertion position. The testing component includes a test ring 11, which is bonded and fixed to the output end of the sleeve 1. The test ring 11 is made of elastic material, and several strain gauges are bonded and fixed on the test ring 11. The strain gauges are evenly arranged and are used to collect the strain information generated by the deformation of the test ring 11.

[0043] Several suction cups 8 are fixedly connected to the bottom outer periphery of the sleeve 1, and the bottom edge of the suction cup 8 is covered with a skin-friendly adhesive layer.

[0044] It also includes a control system, which includes a pressure sensor, a magnetostrictive displacement sensor 9, and a controller. The pressure sensor is bonded and fixed to the side wall of the drive cavity 5, and the controller is bonded and fixed to the inner side wall of the sleeve 1. The strain gauge, pressure sensor, first solenoid valve, second electromagnet 43, and pump assembly 42 are all electrically connected to the controller. The pressure sensor is used to collect the pressure information in the drive cavity 5. The magnetostrictive displacement sensor 9 is used to obtain the needle insertion displacement information based on the change in the magnetic field of the permanent magnet 31 caused by the movement of the beryllium needle body 2. The magnetostrictive displacement sensor 9 is fixedly connected to the bottom wall of the adjustment plate 41. The controller is used to determine whether the sleeve 1 has reached the needle insertion position based on the pressure information, and after the sleeve 1 is in place, it obtains the angle relationship between the tangent of the needle insertion position and the axis of the needle blade 21. Based on the angle relationship, it controls the first electromagnet 32 ​​to work, and when it drives the needle blade 21 to be adjusted so that the axis is perpendicular to the tangent of the needle insertion position, it controls the pump assembly 42 and the second electromagnet 43 to work. The controller is also used to determine the angle between the output plane of the cannula 1 and the cut surface of the needle insertion skin based on the strain information, and to control the first electromagnet 32 ​​to work based on the angle between the output plane of the cannula 1 and the cut surface of the needle insertion skin.

[0045] The specific implementation process is as follows: During the use of this device, the fixed end 23 and the rotating end 22 are inserted into the sleeve 1 in a collinear state. The fixed end 23 drives the fixed ring 44 to deform. The fixed ring 44 restricts the position of the beryllium needle body 2 through its own elasticity and friction. Then, the device is started and the sleeve 1 is moved. The output end of the sleeve 1 is placed at the acupoint, and the suction cup 8 is adsorbed to the skin around the acupoint. The skin-friendly adhesive layer on the bottom wall of the suction cup 8 improves this fixing ability, so that the center of the plane of the output end of the sleeve 1 coincides with the selected needle insertion position.

[0046] At this time, due to the elasticity of human skin, as the output end of the cannula 1 is pressed against the patient's skin, more skin enters the cannula 1, compressing the gas inside and causing the internal air pressure to rise. Simultaneously, the air pressure sensor continuously collects air pressure information from the drive chamber 5. Since the second electromagnet 43 is not operating and its orifice is open, the drive chamber 5 is connected to the regulating chamber 7. Therefore, the air pressure information can reflect the air pressure within the regulating chamber 7 to a certain extent.

[0047] When the air pressure rises, the output end of cannula 1 contacts the patient's skin. If the air pressure fluctuates only within the set range within the set time (approximately 3 minutes), then the air pressure at this time is caused by the patient's skin entering cannula 1. That is, at this time, the output end of cannula 1 is completely in contact with the patient's skin, and the axis of cannula 1 is basically perpendicular to the skin section at the needle insertion point. If the air pressure drops rapidly within the set time and returns to the initial value, then the previous air pressure becomes caused by the patient's skin entering cannula 1. However, since cannula 1 is not completely in contact with the patient's skin, under the action of air pressure, the gas inside cannula 1 flows out from the gap between cannula 1 and the patient's skin, thereby causing the air pressure inside cannula 1 to drop to the initial value. At this time, there is a large angle between the axis of cannula 1 and the skin section at the needle insertion point.

[0048] Therefore, based on the change pattern of air pressure information within a set time, the angle between the axis of the cannula 1 and the skin section at the needle insertion position can be determined. Since the fixed end 23 and the rotating end 22 are collinear in the initial state, the angle between the axis of the beryllium needle body 2 and the skin section can be determined based on the angle between the axis of the cannula 1 and the front of the skin at the needle insertion position.

[0049] To reduce patient discomfort during needle insertion and to enhance the therapeutic effect of acupuncture, needles are inserted vertically.

[0050] When the angle between the beryllium needle body 2 and the patient's skin is nearly perpendicular, the controller activates the second electromagnet 43 to completely close the orifice. Then, the pump assembly 42 is activated to pump gas into the drive chamber 5 until the air pressure in the drive chamber 5 reaches the set value. Afterward, the power to all second electromagnets 43 is cut off. Under the influence of air pressure, the beryllium needle body 2 is pushed towards the patient's skin, completing the insertion. During the insertion process, the relative position of the permanent magnet 31 and the magnetostrictive displacement sensor 9 changes, causing a change in the magnetic field applied by the permanent magnet 31. The controller directly reads the insertion displacement of the beryllium needle body 2 through the magnetostrictive displacement sensor 9. Based on the controller's built-in clock and its control of the pump assembly 42, it ensures timed insertion after each installation, maintaining the insertion depth at 5 mm. This achieves automatic timing for insertion, improving the efficiency of nursing care and the safety of treatment.

[0051] When the beryllium needle body 2 is not perpendicular to the patient's skin, the controller controls the strain gauge to work. The strain gauge collects strain information at various positions of the test ring 11. During the process of the output end of the sleeve 1 contacting the patient's skin, the patient's skin pushes the test gauge to fold inward into the sleeve 1, generating strain information. When the axis of the beryllium needle body 2 is not perpendicular to the cut surface of the patient's skin, the strain information is uneven and shows a certain variation pattern. For example, when the cut surface of the patient's skin is parallel to the horizontal plane, the beryllium needle body 2 tilts to the left. At this time, the force applied to the patient's skin on the right side of the output end of the sleeve 1 is greater than that on the left. Correspondingly, the deformation of the skin near the right side of the patient is more intense than that on the left, resulting in more skin entering the sleeve 1 from the right side than from the left side, and the amount of deformation pushed by the test ring 11 is also greater. Therefore, the strain information collected by the strain gauge arranged on the right side of the test ring 11 is greater than that collected by the strain gauge arranged on the left side of the test ring 11.

[0052] Based on the distribution of strain information, after obtaining the angle between the beryllium needle body 2 and the patient's skin cut surface, the angle required to make the needle blade 21 perpendicular to the skin cut surface at the needle insertion position is determined according to the angle between the beryllium needle body 2 and the patient's skin. Based on this angle, the first electromagnet 32 ​​at the corresponding position is controlled to work. The first electromagnet 32 ​​generates magnetic force, which repels or attracts the permanent magnet 31, thereby pushing the rotating end 22 to rotate and adjusting the angle between the axis of the needle blade 21 and the skin cut surface at the needle insertion position until the axis of the needle blade 21 is perpendicular to the skin cut surface at the needle insertion position.

[0053] When the axis of the needle blade 21 is perpendicular to the cut surface of the skin at the insertion point, the controller controls the second electromagnet 43 to operate. The second electromagnets 43 generate magnetic force and attract each other, stretching the baffle and closing the hole. Then, the controller controls the pump assembly 42 to operate, pumping gas into the drive chamber 5. The gas pressure in the drive chamber 5 gradually rises. When it rises to the set value, the controller cuts off the power supply to the second electromagnet 43 at the corresponding position according to the tilt position of the beryllium needle body 2, so that the gas in the drive chamber 5 enters the adjustment chamber 7, pushing the beryllium needle body 2 to pierce the patient's skin. For example, when the beryllium needle body 2 tilts to the left, the power supply to the second electromagnet 43 located on the right side of the beryllium needle body 2 is cut off, the hole on the right side of the beryllium needle body 2 opens, and under the action of gas pressure, the gas in the drive chamber 5 quickly enters the adjustment chamber 7, acts on the needle handle, and pushes the beryllium needle body 2 towards the patient's skin, finally pushing the needle blade 21 into the patient's skin, completing the insertion to a depth of 5 mm.

[0054] To improve therapeutic efficacy and alleviate patient pain during needle insertion, 2-3 minutes after needle insertion, the controller-controlled pump assembly 42 applies negative pressure to draw in the fixed end 23 of the needle, releasing and springing the needle for treatment. After the treatment time is up, medical staff retrieve the cannula 1 and the needle body 2, automating the painless meridian beryllium needle therapy, thereby improving treatment efficiency and reducing the waste of medical staff's manpower. Compared to existing technologies, this solution, through the design of a pressure sensor and a test ring 11, determines the insertion angle of the beryllium needle body 2 by measuring the internal air pressure of the cannula 1 and the deformation state of the test ring 11, improving the accuracy of needle insertion. Simultaneously, if the insertion angle is inappropriate, the needle blade 21 is automatically adjusted, thereby reducing pain during the needle insertion process.

[0055] Example 2:

[0056] As attached Figure 3 As shown, the difference from Embodiment 1 is that the drive chamber 5 is also provided with a accumulator 6, the pump assembly 42 is connected to the accumulator 6, and both the accumulator 6 and the connection between the drive chamber 5 and the pump assembly 42 are provided with solenoid valves. The accumulator 6 is connected to the drive chamber 5, and a pressure relief valve is provided at the connection between the accumulator 6 and the drive chamber 5.

[0057] The specific implementation process is as follows: Before using this device, the operator can control the pump assembly 42 and the solenoid valve to operate, pumping gas into the accumulator chamber 6 through the pump assembly 42. As the gas pressure in the accumulator chamber 6 rises, it reaches the threshold of the pressure relief valve, which then opens, allowing gas to enter the drive chamber 5. Since the second solenoid valve is closed at this time, the orifice is open. After the gas enters the regulating chamber 7, it leaves the device through the output end of the sleeve 1. When the operator feels gas flow at the output end of the sleeve 1, the pump assembly 42 can be shut off. In subsequent use, when the controller controls the first electromagnet 3... 2. In operation, after adjusting the angle of the needle blade 21 to be perpendicular to the patient's skin, the controller first activates the solenoid valve at the corresponding position, so that the pressurized gas in the accumulator 6 enters the drive chamber 5. If the gas pressure information in the drive chamber 5 reaches a suitable value at this time, the power supply of the second electromagnet 43 at the corresponding position is cut off, and the beryllium needle body 2 is driven by the gas pressure to pierce the patient's skin. If the gas pressure information does not reach a suitable value at this time, the controller activates the pump assembly 42 and the solenoid valve at the corresponding position to pump gas into the drive chamber 5 again, continuing to increase the pressure in the drive chamber 5 until a suitable pressure is reached.

[0058] After the previous needle insertion is completed, the controller controls the pump assembly 42 and the corresponding solenoid valve to open, and the pump assembly 42 pumps gas into the accumulator chamber 6 for use in subsequent needle insertions.

[0059] Compared to existing technologies, this solution, through the design of the accumulator chamber 6, can significantly reduce the time required for the driving chamber to accumulate pressure during needle insertion by pre-accumulating pressure. This reduces the time required for needle insertion and alleviates patient fear and resistance. Furthermore, compared to the solution using the driving chamber 5 for pre-accumulation pressure, this solution avoids the second electromagnet 43 being in the open state for extended periods, preventing unnecessary energy loss. It also avoids fatigue fracture caused by prolonged stretching of the baffle under air pressure, thus reducing the lifespan of the device.

[0060] The design of the pressure relief valve in this solution, compared to the use of solenoid valves, can reduce the number of sensors used in the device, reduce the amount of calculation in the controller, and achieve the goal of reducing the cost of the device.

[0061] Example 3:

[0062] As attached Figure 1 As shown, the difference from Embodiment 2 is that a heating wire is welded and fixed inside the driving cavity 5. The heating wire is used to heat the gas inside the driving cavity 5. The control system also includes a temperature sensor. The temperature sensor is bonded and fixed to the side wall of the regulating cavity 7. Both the temperature sensor and the heating wire are electrically connected to the control system. The temperature sensor is used to collect the temperature information of the needle blade 21. The controller controls the operation of the heating wire according to the temperature information.

[0063] The specific implementation process is as follows: During the use of this device, the operator determines whether the patient is suitable for warm acupuncture based on the patient's actual condition. If the patient is suitable, the operator activates the heating wire before inserting the needle. The heating wire heats the gas in the drive chamber 5, and the heat is transferred to the beryllium needle body 2 through the regulating plate 41, causing the temperature of the beryllium needle body 2 to rise. At the same time, during the subsequent needle insertion process, the heated gas acts on the beryllium needle body 2 and transfers heat to the needle blade 21 and other positions, thereby achieving the heating treatment of the beryllium needle body 2.

[0064] Compared to existing technologies, this solution can independently heat the beryllium needle body 2, achieving the purpose of warming and unblocking the meridians and promoting blood circulation. Compared to solutions using external heat sources, this solution reduces acupuncture steps and avoids safety accidents such as fires caused by external heat sources, thus improving operational safety. Furthermore, by heating the driving cavity 5, compared to solutions that heat other areas, it promotes the expansion of air inside the driving cavity 5, further increasing the air pressure inside the driving cavity 5. This increases the force exerted by the gas inside the driving cavity 5 on the beryllium needle body 2, thereby reducing the likelihood of the beryllium needle body 2 being difficult to push out with air pressure, which could lead to needle insertion failure.

[0065] When using this device, the temperature sensor continuously collects the temperature information of the needle blade 21. When the heating wire is turned on, the controller determines whether the needle blade 21 has reached the appropriate temperature based on the temperature information. After the needle blade 21 reaches the appropriate temperature, the controller cuts off the power to the heating wire. Compared with the prior art, the design of the temperature sensor can reduce the risk of burns to patients caused by excessive temperature of the needle blade 21. At the same time, due to the design of the sleeve 1, there is a large temperature difference when the temperature of the needle blade 21 is transferred to the operator's hand. The design of the temperature sensor can avoid the judgment errors caused by this temperature difference and improve the safety of the device.

[0066] Example 4:

[0067] As attached Figure 1 As shown, the difference from Embodiment 3 is that an alarm component is also included. In this embodiment, the alarm component is an indicator light. The alarm component is used to alert the user. The alarm component is electrically connected to the controller. The controller determines whether the output end of the cannula 1 is in contact with and fully adheres to the patient's skin based on air pressure and strain information. If the output end of the cannula 1 does not fully adhere to the patient's skin within a set time after contact, the controller controls the alarm component to alert the user. The controller is also used to control the alarm component to alert the user after the temperature information reaches a set temperature. The controller determines whether the beryllium needle body 2 has been successfully inserted based on the strain information change trend, and only controls the alarm component to alert the user after successful insertion.

[0068] The specific implementation process is as follows: When using this device, the controller determines whether the output end of the cannula 1 is in contact with the patient's skin based on the air pressure information and strain information. When the air pressure information and strain information change synchronously, the output end of the cannula 1 is in contact with the patient's skin. When the output end of the cannula 1 is in complete contact with the patient's skin, the air pressure information no longer changes significantly, and the strain information collected by most strain gauges changes. If the output end of the cannula 1 still cannot make contact with the patient's skin within a set time after it has made contact, then the cannula 1 is in an unreasonable position, which may affect the quality of subsequent needle insertion. At this time, the controller activates the alarm to prompt the user to make adjustments to improve the accuracy of subsequent needle insertion.

[0069] Meanwhile, after the operator starts the heating wire, as the temperature of the beryllium needle body 2 rises to the set temperature, the controller controls the alarm component to work, prompting the user to proceed with the subsequent needle insertion operation. At this time, the set temperature is slightly lower than the temperature required by the beryllium needle body 2 when inserting the needle, so as to avoid damage to the patient caused by the heat brought by the heating gas on the beryllium needle body 2 during the needle insertion process.

[0070] During needle insertion, when the needle blade 21 successfully enters the skin, the skin and other structures possess a certain degree of elasticity, allowing the needle blade 21 to retract a certain distance after insertion. The skin then returns to its original position under its own elastic force. As the skin retracts, the test ring 11 gradually returns to its original position under its own elastic force, and the strain information gradually decreases. Once the skin returns to its original position, the strain information gradually recovers to near its original value. However, if the beryllium needle body 2 fails to insert successfully, the needle blade 21 does not enter the patient's skin. In this case, the changes in the patient's skin are caused by changes in the air pressure within the regulating chamber 7. The strain information will still decrease, but it will not recover to near its original value.

[0071] Therefore, the success of needle insertion is determined based on the pattern of strain information changes. The controller only activates the alarm component after successful needle insertion, alerting the user to remove the sleeve 1 and other structures. Compared with existing technologies, this solution can prevent users from removing the sleeve 1 and other structures during needle insertion, thus avoiding human-induced needle insertion failure. In addition, keeping the sleeve 1 stationary when needle insertion fails due to non-human factors also helps improve the accuracy of re-accumulating pressure and driving the beryllium needle body 2 for needle insertion.

[0072] Example 5:

[0073] As attached Figure 1 As shown, the difference from Embodiment 4 is that a number of elastic material spacers 12 are bonded and fixed inside the adjustment cavity 7, and the spacers 12 are evenly arranged.

[0074] The specific implementation process is as follows: When using this device, the partition 12 can isolate the regulating cavity 7 into several chambers, thereby adjusting the direction of the pressurized gas entering the regulating cavity 7 to a certain extent, and preventing it from entering the surrounding chambers under the action of air pressure, causing the pressurized gas pressure to drop and affecting the pushing effect on the beryllium needle body 2.

[0075] 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.
