Description

Technical Field

[0001] The present application belongs to the field of vascular puncture technology, and more specifically, relates to a device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion. Background Art

[0002] The establishment of deep vascular access is the "first line of defense" for maintaining life and is widely used in high-risk scenarios such as intensive care, hemodialysis, central venous nutrition, and intraoperative high-flow infusion. Especially for critically ill patients with shock, massive blood loss, severe trauma, respiratory failure, and cardiopulmonary resuscitation, establishing access in seconds not only determines whether treatment can be quickly initiated, but also directly affects the patient's survival rate and prognosis. The establishment of deep vascular access (including deep vein artery puncture and catheterization) has the following characteristics:

[0003] 1. Clinical necessity: deep vascular access as a “lifeline”

[0004] In critical care, hemodialysis, central venous nutrition, and intraoperative high-flow infusions, deep venous or arterial access is the primary prerequisite for initiating various treatments. Especially in critically ill patients like shock, massive bleeding, severe trauma, respiratory failure, and cardiopulmonary resuscitation, every second counts: The speed of access establishment directly affects lifespan and the success of treatment.

[0005] 2. Current bottleneck: Traditional methods are inefficient and risky

[0006] Currently, puncture operations rely heavily on the doctor's anatomical experience, hand feel, and subjective judgment of blood color and flow rate. In conditions of hypotension, hypoxia, metabolic abnormalities, etc., blood color and flow rate characteristics are easily distorted, resulting in unstable catheterization success rates and frequent complications. Although ultrasound guidance can be used as an auxiliary tool, it is large in size, has a cumbersome process, and relies on professional training, making it difficult to meet the emergency and portability needs of primary hospitals and emergency transport.

[0007] 3. Technical Challenge: Difficulty Identifying Deep Arteries and Veins

[0008] Deep blood vessels are located deep, have complex anatomical courses, are invisible to the naked eye, and have a vague sense of touch. They differ significantly from superficial blood vessels in inner diameter, blood flow dynamics, and pulsation characteristics. The traditional judgment method relies on the color of the returning blood (bright red in the arteries, dark red in the veins) and pulsation, which is easily interfered by factors such as hypotension, hypoxia, and high bilirubin, and the risk of misjudgment is serious. Summary of the Invention

[0009] The purpose of the embodiments of the present application is to provide a device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion, so as to solve the technical problems existing in the prior art that traditional technologies cannot accurately identify deep arteries and veins, have high operational risks and low efficiency.

[0011] Furthermore, the sensing module includes a blood flow monitoring element, which is used to detect the direction, rate and inner diameter of blood vessels in real time and provide arteriovenous identification data.

[0012] Furthermore, the sensing module also includes a pressure monitoring element, which is used to continuously detect the pressure difference in the blood vessel, determine the artery and vein, and adjust the puncture position in real time.

[0013] Furthermore, the sensing module further includes a pulsation monitoring element, which is used to capture blood vessel pulsation signals to verify the properties of the target blood vessel.

[0014] Furthermore, the sensing module also includes an optical blood oxygen monitoring element, which uses near-infrared spectroscopy technology to detect the oxygen saturation in the blood.

Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0029] See also Figure 1 , the device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion provided in an embodiment of the present application is now described. The device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion includes a device body 100, a puncture needle 200, a guide wire tube 300 and a sensing module 400; the puncture needle 200 is arranged inside the device body 100; the guide wire tube 300 passes through the device body 100 and is connected to the puncture needle 200; the guide wire tube 300 is used for a guide wire (not shown) to pass through; the sensing module 400 is arranged outside the device body 100, and the sensing module 400 is used to monitor the state of the blood vessels.

[0030] Compared with the existing technology, the device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion provided in the present application can automatically identify arteries and veins and optimize the puncture path by setting a sensing module 400 in the embodiment of the present application, effectively solving the problems of easy misjudgment of arteries and veins, inability to quickly establish vascular access, and the risk of accidental puncture of arteries in traditional vascular puncture technology; ensuring the accuracy and safety of the entire catheterization operation and reducing complications and errors in clinical operations.

[0031] In one embodiment of the present application, the sensing module 400 includes a blood flow monitoring element (not shown), which is used to detect the direction, rate and inner diameter of blood vessels in real time and provide arteriovenous identification data.

[0032] In this embodiment, by providing a blood flow monitoring element, dynamic blood flow information can be acquired in real time, including important parameters such as blood flow direction, velocity, and vessel diameter. This information provides key data support for accurate identification of arteries and veins, thereby greatly improving puncture accuracy and reducing errors that rely on operator experience.

[0033] Furthermore, the use of a blood flow monitoring element enables the device to fully assess the target vessel before puncture, ensuring that the selected vessel is both suitable for puncture and meets the treatment requirements. During the puncture process, the blood flow monitoring element continuously monitors blood flow. If an abnormality is detected, such as a sudden drop in blood flow rate or an abnormal change in the vessel's inner diameter, the device will immediately sound an alarm, prompting the operator to take appropriate measures to avoid potential risks.

[0034] Specifically, blood flow monitoring components can use ultrasonic Doppler sensors. By emitting ultrasonic waves and receiving reflected signals, the Doppler effect allows accurate measurement of blood flow velocity and direction. Combined with measurements of the inner diameter of blood vessels, this provides precise data for arteriovenous identification. This non-invasive monitoring method not only improves measurement accuracy but also ensures patient comfort.

[0035] In one embodiment of the present application, the sensing module 400 further includes a pressure monitoring element (not shown), which is used to continuously detect the pressure difference within the blood vessel, determine the artery and vein, and adjust the puncture position in real time.

[0036] In this embodiment, the provision of a pressure monitoring element enables continuous monitoring of intravascular pressure differences, further enhancing the accuracy of arteriovenous identification. Because arteries and veins exhibit significant differences in pressure characteristics, the pressure monitoring element leverages this difference to accurately distinguish between arteries and veins by monitoring intravascular pressure changes in real time, thereby guiding puncture needle 200 for precise puncture. Furthermore, the pressure monitoring element can adjust the puncture position in real time based on changes in intravascular pressure, ensuring that puncture needle 200 remains on the optimal puncture path, further improving the success rate and safety of the puncture.

[0037] Specifically, the pressure monitoring element can use a pressure sensor that can accurately measure pressure changes within the blood vessel. During the puncture process, the pressure sensor can monitor and feedback the pressure data within the blood vessel in real time. The control system analyzes and judges based on this data, thereby achieving precise control of the puncture position. This real-time monitoring and control mechanism not only improves the accuracy of the puncture, but also ensures the safety of the puncture process and reduces the risk of accidentally puncturing an artery. At the same time, the use of a pressure sensor also enables the device to adapt to the vascular characteristics of different patients, improving the applicability and flexibility of the device.

[0038] In one embodiment of the present application, the sensing module 400 further includes a pulsation monitoring element (not shown), which is used to capture blood vessel pulsation signals to verify the properties of the target blood vessel.

[0039] In this embodiment, by providing a pulsation monitoring element, the pulsation of the blood vessel can be monitored in real time, further verifying the properties of the target blood vessel. By capturing the pulsation signal of the blood vessel, the pulsation monitoring element can determine the elasticity and vitality of the blood vessel, thereby assisting in confirming whether it is a target vessel suitable for puncture. This function is particularly important during the puncture operation because it can help the operator avoid selecting blood vessels with poor elasticity or lesions, reducing the risk of puncture failure and complications. In addition, the real-time monitoring capability of the pulsation monitoring element also enables the device to respond to changes in the blood vessel status in a timely manner during the puncture process, ensuring the safety and effectiveness of the puncture operation.

[0040] Specifically, the pulsation monitoring element can use a photoelectric sensor. This sensor accurately captures the vascular pulsation signal by emitting light and receiving the changes in reflected light caused by blood vessel pulsation. This non-contact monitoring method not only improves measurement accuracy but also avoids causing additional irritation or discomfort to the patient.

[0041] In one embodiment of the present application, the sensing module 400 also includes an optical blood oxygen monitoring element (not shown), which uses near-infrared spectroscopy technology to detect the oxygen saturation in the blood. Different wavelengths of light have different absorption characteristics in arterial blood and venous blood, which helps distinguish between arteries and veins.

[0042] In this embodiment, an optical blood oximetry element is provided to monitor the oxygen saturation in the patient's blood in real time, providing another important basis for distinguishing between arteries and veins. Near-infrared spectroscopy technology can penetrate skin and tissue to directly detect blood components. Different wavelengths of light are absorbed significantly differently in arterial and venous blood, and these differences are captured and analyzed by the optical blood oximetry element, allowing accurate determination of vessel type. The addition of this feature further enhances the accuracy and safety of the device, particularly when handling complex cases or emergency situations, by providing the operator with more comprehensive and reliable vascular information to ensure the successful execution of the puncture procedure.

[0043] Specifically, the optical blood oxygen monitoring element can be in the form of a combination of a light-emitting diode (LED) and a photodetector. The LED emits near-infrared light of different wavelengths, which penetrates the skin and tissues and is absorbed by the hemoglobin in the blood. The photodetector receives the unabsorbed light and converts it into an electrical signal. By analyzing the intensity changes of these electrical signals, the optical blood oxygen monitoring element can calculate the oxygen saturation in the blood and assist in distinguishing between arteries and veins. This non-invasive monitoring method not only improves the patient's comfort, but also ensures the accuracy and real-time nature of the monitoring results.

[0044] In one embodiment of the present application, the device further includes a control system (not shown), which is electrically connected to the sensing module 400 .

[0045] In this embodiment, a control system is provided to enable rapid processing and analysis of data acquired by the sensing module 400. As the core component of the device, the control system plays a crucial role. It not only receives real-time data from the sensing module 400 but also makes intelligent decisions based on this data to guide the puncture procedure.

[0046] In one embodiment of the present application, the control system includes a data processing module (not shown), which is used to comprehensively analyze various types of data acquired by the sensing module 400.

[0047] In this embodiment, a data processing module is also provided, which has powerful data processing and analysis capabilities. It can receive multi-source data from the sensing module 400, including blood flow direction, rate, blood vessel diameter, intravascular pressure, blood vessel pulsation signal, and oxygen saturation in the blood, and integrate, clean, and calibrate these data to ensure the accuracy and reliability of the data. Subsequently, the data processing module uses advanced algorithms and models to conduct in-depth analysis and mining of these data, extracting key information and providing strong support for subsequent decision-making and regulation. Through the precise analysis of the data processing module, the control system can evaluate the effect of the puncture operation in real time, promptly detect and correct possible deviations, and ensure the accuracy and safety of the entire puncture process.

[0048] Specifically, the data processing module can utilize a high-performance microprocessor or dedicated data processing chip. These processors or chips offer high-speed computing capabilities and low power consumption, enabling efficient processing of large amounts of data while ensuring real-time performance and accuracy. Furthermore, the data processing module possesses self-learning and optimization capabilities, continuously optimizing analysis algorithms and decision-making models based on historical data and operational experience to enhance the accuracy and safety of punctures. This intelligent data processing approach not only enhances device performance but also brings greater convenience and safety to clinical operations.

[0049] In an embodiment of the present application, the sensing module 400 integrates multiple sensing elements such as blood flow monitoring elements, pressure monitoring elements, pulsation monitoring elements, optical blood oxygen monitoring elements, etc., and performs comprehensive analysis through deep learning of the data processing module, which can achieve high-precision automatic classification of arteries and veins.

[0050] In one embodiment of the present application, the control system further includes an automatic positioning module (not shown), which is used to adjust the puncture angle and depth according to the analysis results of the data processing module.

[0051] In this embodiment, an automatic positioning module is provided to precisely control the puncture angle and depth. During the puncture process, the automatic positioning module receives analysis results from the data processing module and automatically adjusts the angle and depth of the puncture needle 200 based on the characteristics of the vessel and the puncture requirements, ensuring that the puncture needle 200 enters the vessel along the optimal path, reducing the risk of surrounding tissue damage and arterial puncture. This feature significantly reduces the operator's workload and improves the success rate and efficiency of punctures.

[0052] Specifically, the automatic positioning module can use advanced sensor fusion technology and intelligent algorithms in synergistic combination to achieve the purpose of accurately adjusting the puncture angle and depth according to the analysis results of the data processing module. Multivariate data such as blood vessel position, morphology, blood flow status, etc. collected by various sensors are deeply integrated and analyzed with the help of intelligent algorithms to accurately determine the most appropriate puncture angle and depth parameters. During the puncture operation, the angle and depth of the puncture needle 200 are automatically and finely adjusted according to the parameters obtained from these precise analyses, minimizing the possibility of damage to surrounding tissues and effectively avoiding the occurrence of risky situations such as accidental puncture of arteries. In this way, not only the accuracy and success rate of the puncture operation are greatly improved, but also the safety and comfort of the patient during the entire puncture process are further guaranteed.

[0053] In one embodiment of the present application, see Figure 1 The control system further includes an indication module 500 , which is mounted on the outside of the device body 100 and is used to display the puncture status.

[0054] In this embodiment, the indicator module 500 is provided to intuitively display key information during the puncture process to the operator. Using a clear display screen or indicator lights, the indicator module 500 displays important data such as the position of the puncture needle 200, the state of the blood vessel, and blood flow parameters in real time, allowing the operator to quickly understand the puncture progress and make appropriate adjustments. This feature not only improves the transparency of the puncture operation but also enhances the operator's control over the entire process, further improving the safety and success rate of the puncture.

[0055] In one embodiment of the present application, the indication module 500 includes a first indicator light, a second indicator light, a third indicator light and a fourth indicator light; the first indicator light is electrically connected to the blood flow monitoring element, the second indicator light is electrically connected to the pressure monitoring element, the third indicator light is electrically connected to the pulse monitoring element, and the fourth indicator light is electrically connected to the optical blood oxygen monitoring element.

[0056] Each indicator light displays the status information detected by its own monitoring element through different colors or flashing modes. For example, when the blood flow monitoring element detects that the blood flow direction is correct, the rate is moderate, and the inner diameter of the blood vessel is appropriate, the first indicator light lights up green; if an abnormality is detected, the red light lights up and flashes to alert the operator. Similarly, the second indicator light, the third indicator light, and the fourth indicator light also correspond to the detection results of the pressure monitoring element, the pulse monitoring element, and the optical blood oxygen monitoring element, respectively, providing the operator with comprehensive and intuitive puncture status feedback. The first indicator light, the second indicator light, the third indicator light, and the fourth indicator light all display green to indicate that it is safe to puncture. If one indicator light displays red, it means that it is not safe to puncture. This design allows the operator to quickly identify and respond to various status changes during the puncture process to ensure the smooth progress of the puncture operation.

[0057] In one embodiment of the present application, see Figure 1 A one-way valve 201 is provided in the puncture needle 200 to prevent blood from flowing back and air from entering.

[0058] In this embodiment, the provision of a one-way valve 201 effectively prevents blood from flowing back into the puncture needle 200, avoiding blood contamination and unnecessary blood loss. Furthermore, the one-way valve 201 effectively blocks outside air from entering the circulatory system, significantly reducing the risk of air embolism and providing a safer puncture treatment environment for patients. This design demonstrates a high level of concern for patient safety after surgery and a thorough consideration of reducing postoperative complications. The use of the one-way valve 201 not only enhances the functionality and safety of the device but also brings greater convenience and assurance to clinical procedures.

[0059] In one embodiment of the present application, see Figure 1 The device also includes a button 600, which is connected to the puncture needle 200 and is used to control the forward and backward movement of the puncture needle 200. The operator can easily achieve precise control of the puncture needle 200 by pressing or releasing the button 600. This user-friendly design makes operation simpler and more intuitive. Furthermore, the button 600 has a clear tactile feel and timely feedback, ensuring precise control during the puncture process, further improving the safety and success rate of the puncture.

[0060] The working process of the device for intelligent identification and positioning of deep arteries and veins based on multimodal fusion provided in the embodiment of the present application is as follows:

[0061] During the puncture preparation phase, the operator first observes and confirms the status of the target vessel using the indicator module 500 of the device body 100. When the first, second, third, and fourth indicators all illuminate green, it indicates that the puncture is safe to proceed. At this point, the operator presses button 600, slowly directing the puncture needle 200 toward the target vessel.

[0062] During the puncture process, the various monitoring elements of the sensing module 400 operate in real time, collecting key data such as blood flow direction, velocity, inner diameter, pressure, pulsation signal, and oxygen saturation in the blood. This data is rapidly transmitted to the control system for comprehensive analysis and processing by the data processing module. Based on the analysis results, the automatic positioning module automatically adjusts the angle and depth of the puncture needle 200 to ensure that the puncture needle 200 enters the blood vessel along the optimal path.

[0063] At the same time, the indicator module 500 continuously displays key information during the puncture process, such as the position of the puncture needle 200 and the status of the blood vessel, allowing the operator to understand the puncture progress in real time and make fine adjustments as needed. If any abnormality is detected, such as a sudden drop in blood flow rate or an abnormal change in the inner diameter of the blood vessel, the device will immediately sound an alarm, prompting the operator to stop the puncture and take appropriate measures.

[0064] During the entire puncture process, the device achieves precise control and safety assurance of the puncture operation through the integrated sensing module 400, advanced control system and humanized operation design, greatly improving the success rate of puncture and patient comfort.

[0065] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
