Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a multifunctional intelligent mobile infusion instrument, specifically a "Lingyetong" wristband infusion instrument. Background Art

[0002] Currently, in the field of medical infusion, both traditional infusion equipment and existing portable infusion devices have significant drawbacks. Traditional infusion methods rely on infusion bottles or bags combined with disposable infusion tubing, and deliver medication based on the principle of liquid weight and atmospheric pressure. In this method, infusion speed regulation relies on mechanical pulleys to compress the infusion tubing, which not only has limited adjustment accuracy but also poor reliability. Furthermore, long periods of accompanying care can easily lead to fatigue and negligence, requiring nurses to conduct frequent inspections to ensure infusion safety, which undoubtedly increases their workload and has a negative impact on the overall management of the ward.

[0003] Existing portable infusion sets also face significant challenges. In terms of infusion accuracy, they lag significantly behind traditional large-scale infusion devices. When administering specialized medications or targeting specific populations like children and the elderly, infusion rates can be unstable and subject to significant errors. This can lead to poor therapeutic efficacy and even serious adverse reactions, compromising the patient's treatment safety and recovery progress. Battery life is also unsatisfactory. During prolonged infusions or in environments where charging is unavailable, such as outdoors, the battery can easily run out, interrupting the infusion and causing significant inconvenience for the patient. In emergency situations, such as first aid, this can seriously impact treatment effectiveness. Furthermore, portable infusion sets have poor reliability and durability. After repeated use or minor impact or vibration, they are prone to malfunctions such as clogged infusion lines, leaks, and electronic component damage. This not only reduces the product's lifespan and cost-effectiveness, increases patient costs and medical burdens, but also undermines patient trust and hinders market adoption and development. Regarding user experience, some portable infusion sets are complex to operate. For elderly patients, those with limited education, or in emergency situations, it can be difficult to quickly master correct usage, increasing the difficulty and psychological burden of use, potentially leading to incorrect operation and compromising treatment effectiveness. Furthermore, during prolonged infusions, some product designs fail to fully consider ergonomic principles, resulting in discomfort. These issues, such as infusion lines pressing against the skin and fixtures being too tight or too loose, reduce the patient experience, potentially causing resistance and impacting treatment compliance. Balancing portability with functional integrity also struggles to meet diverse user needs. Some products sacrifice functionality or reduce infusion capacity in pursuit of compactness and lightness, while some powerful products are bulky and heavy, making them difficult to carry. In terms of market and regulation, portable infusion sets are relatively expensive, limiting their market penetration and patient accessibility. Furthermore, market awareness is insufficient, leaving many patients and healthcare professionals with limited understanding of their advantages and applicable scenarios. Medical institutions harbor concerns about the safety and effectiveness of new products and are reluctant to easily try and promote them. Furthermore, incomplete regulatory standards have led to uneven product quality on the market, posing safety risks and creating uncertainty for companies' R&D, production, and sales.

[0004] After searching, the application publication number CN115137908A is an intelligent infusion device installed in the emergency transfer and treatment equipment for the wounded. The intelligent infusion device includes a main body, on which an infusion unit, an injection unit, a heating unit, a vital sign monitoring unit, a control unit and a network communication unit are integrated. Among them, the control unit is electrically connected to the infusion unit, the injection unit, the heating unit, the vital sign monitoring unit and the network communication unit respectively. Among them, the vital sign monitoring unit is used to connect each vital sign monitoring sensor, and collect and analyze the monitored vital sign information, and feed back the monitored vital sign information to the control unit to control the infusion unit and the injection unit to guide the use of medicines based on the monitored vital sign information. Among them, the main body is provided with a communication interface, a control interface, an ECG lead interface and a blood pressure cuff interface. By this means, the intelligent infusion device of the present invention has a high degree of integration and is easy to carry. It can meet the needs of liquid medicine infusion treatment and management for patients under extreme natural disaster conditions, and improves the efficiency of treatment for critically ill patients.

[0005] Compared with the intelligent infusion device of application publication number CN115137908A, the present invention has significant differences and optimizations in terms of technical integration, precise control, user experience and data security. First, although CN115137908A integrates multiple units, it does not mention the infusion precision control technology. The present invention innovatively develops an adjustable infusion control system with an accuracy of 0.01ml. It uses the ESP32 main control chip combined with an intelligent algorithm to achieve dynamic adjustment of the infusion speed, which is more than 50 times more accurate than the traditional mechanical adjustment method, especially meeting the needs of children and elderly patients for precise drug delivery. Secondly, the patented vital sign monitoring unit is only for information collection and feedback, and does not achieve deep fusion of multimodal data. The present invention uses a self-developed integrated three-light source LED and a wide-spectrum optical sensor to integrate multi-dimensional data such as pulse waveform, blood oxygen value, and vascular microcirculation parameters. It outputs more accurate vital sign monitoring results through advanced data fusion algorithms, which is 30% more accurate than single sensor monitoring. In terms of user experience, CN115137908A does not involve improvements to puncture technology. The present invention uses nano-needle dermal puncture technology, with the needle diameter controlled at 100 nanometers to several microns, which is more than 80% smaller than the cross-sectional area of traditional needles. Combined with the angle-depth intelligent control algorithm, it achieves painless puncture and reduces tissue damage by 75%, significantly improving patient comfort. In addition, the patent does not mention the heating function and interactive design. The present invention integrates a liquid heating module, stabilizes the liquid temperature at 37±0.5℃ through a PID temperature control algorithm, and is equipped with a high-definition touch screen and a TTS neural network voice recognition system, which supports fault-tolerant processing of voice commands. Compared with traditional key operations, the efficiency is increased by 60%, which is particularly suitable for medical staff to operate quickly in extreme environments. In terms of data security and remote control, CN115137908A does not involve data encryption and redundant design. The present invention uses blockchain technology to decentralize the storage of infusion records and vital signs data to ensure that the data cannot be tampered with. At the same time, it builds a dual-wireless dual-channel backup communication system (including Huawei Star Flash technology) with a real-time communication distance of 1km, which is 40% more stable than the traditional single-channel network. It also uses the 777 permission management mechanism and SSL / TLS encryption technology to ensure remote control security and data transmission reliability. Summary of the Invention

[0006] The present invention aims to solve the above problems of the prior art. It proposes a multifunctional intelligent mobile infusion device and a control method thereof. The technical solution of the present invention is as follows:

[0007] A multifunctional intelligent mobile infusion instrument, which includes: a real-time monitoring system, which includes a pulse wave sensor, a blood oxygen sensor, and a heart rate sensor for real-time collection of patients' vital signs data; a precise infusion control pump, which is used to accurately control the infusion volume; a liquid heating module, which adjusts the temperature of the infusion liquid according to the patient's needs; a nanoneedle dermal puncture device and its control system, which ensure painless infusion; a spectral blood vessel recognition system, which automatically identifies the location of blood vessels; a wireless communication module, which supports remote data transmission and equipment control, allowing medical staff to monitor the patient's infusion status at different locations; a user interaction interface, including a touch screen and voice recognition control, which is used for device operation and status display, facilitating user operation and information acquisition.

[0008] Furthermore, the precise infusion control pump adopts a closed-loop control mechanism, and its core steps are as follows: first, the output flow rate of the infusion pump and the dynamic data of the patient's venous return are collected in real time through a high-precision flow sensor, and input into the ESP32 main control chip after analog-to-digital conversion; then the real-time flow rate data is calculated with the target flow rate of the preset treatment plan, and the fuzzy PID control algorithm is used to generate the adjustment instruction to drive the micro servo motor to adjust the opening degree of the infusion pipeline pressure valve; at the same time, the venous pressure data fed back by the pressure sensor is integrated, the noise interference is filtered through the adaptive filtering algorithm, and the control parameters are dynamically corrected to form a closed-loop adjustment circuit of "data acquisition-deviation calculation-instruction output-feedback correction" to ensure that the infusion speed error is controlled within ±0.01ml / h.

[0009] By real-time monitoring of the difference between the patient's venous return and the infusion pump output, the infusion speed is automatically adjusted to ensure precise control of the infusion volume.

[0010] Furthermore, the device also includes an integrated intelligent algorithm module. First, the vital sign data (blood pressure, blood oxygen, heart rate, body temperature, etc.) collected by multiple sensors are normalized and preprocessed, and high-frequency noise is removed through wavelet transform. This is then input into an LSTM-based time series prediction model, combined with static data such as the patient's age, weight, and medical history, to construct an individualized physiological state feature vector. A decision tree algorithm is then used to match the preset clinical medication guidelines to generate initial infusion rate, drug dosage, and heating temperature parameters. A reinforcement learning algorithm is then used to dynamically optimize the initial plan. Using the patient's real-time vital sign fluctuations as the reward function input, the control parameters are iteratively adjusted to maintain the drug solution temperature within the comfortable range of 37±0.5°C, while ensuring that the infusion rate matches the patient's cardiopulmonary function load. Finally, an adaptive threshold algorithm is used to set abnormal alarm boundaries. When the vital sign data deviates from the safe range, an audible and visual alarm and a remote communication module are triggered, realizing an intelligent process from data processing, plan generation, to dynamic control. This module can analyze the patient's vital sign data and automatically recommend a personalized infusion plan, including infusion rate, drug dosage, and heating temperature settings, to optimize the treatment effect.

[0011] Furthermore, in the nanoneedle dermal puncture technology, the nanoneedle array is designed as a replaceable module, allowing the needle to be replaced under sterile conditions, ensuring hygiene, safety and puncture effect during multiple uses.

[0012] Furthermore, the real-time monitoring system adopts multimodal biosignal analysis technology, which can simultaneously monitor and analyze multiple vital signs such as blood pressure, blood oxygen, heart rate, and body temperature, and provide a comprehensive patient health status report.

[0013] Furthermore, the device is equipped with an intelligent alarm system, which can not only monitor abnormalities during the infusion process, but also predict equipment failures, provide early warnings, and reduce the risk of infusion interruption.

[0014] Furthermore, the wireless communication module supports Bluetooth 5.0 and Wi-Fi dual-band, ensuring stable remote data transmission and device control both within hospitals and home environments.

[0015] Furthermore, the device has a built-in blockchain node and uses public-private key encryption technology to ensure the secure transmission and storage of every infusion record and vital signs data, in compliance with HIPAA medical privacy regulations.

[0016] Furthermore, the wristband part of the device is equipped with a pressure sensor, which can monitor the pressure of the infusion line on the skin in real time, and adjust the line fixing method in combination with an intelligent algorithm to reduce the possibility of local blood circulation obstruction and improve patient comfort.

[0017] A control method based on any of the multifunctional intelligent mobile infusion devices, comprising the following steps: S1, collecting the patient's vital sign data in real time, wherein the vital sign data includes blood pressure, blood oxygen, heart rate and respiration;

[0018] S2, dynamically adjusting the infusion speed of the precise infusion control pump according to the vital sign data to ensure precise control of the infusion process;

[0019] S3, automatically identifying the location of blood vessels using the spectral blood vessel recognition system;

[0020] S4, using the nanoneedle dermal puncture device to achieve painless infusion;

[0021] S5, adjusting the temperature of the infusion liquid by the liquid heating module according to the patient's needs to maintain a suitable infusion temperature;

[0022] S6, realizing data transmission and remote control with external devices through the wireless communication module, supporting remote monitoring by medical staff;

[0023] S7, device operation and status display are performed through the user interaction interface, and the user interaction interface supports touch screen operation and voice recognition control to simplify the operation process and enhance the user experience.

[0024] The advantages and beneficial effects of the present invention are as follows:

[0025] 1. Improve treatment safety and effectiveness: High-precision infusion control and real-time vital signs monitoring can promptly detect and address abnormal conditions during the infusion process, effectively ensuring patient treatment safety, reducing the occurrence of adverse reactions, and improving treatment outcomes.

[0026] 2. Improve patient experience: Features such as painless infusion, liquid heating, comfortable appearance design, and intelligent voice interaction fully consider the needs of patients, greatly improving the patient's infusion experience and enhancing patient treatment compliance.

This data includes physiological sensor data transmitted from interface 21 and infusion line data collected by flow or pressure sensors at interface 510. Based on the analysis results, the main control chip issues precise control commands to other functional modules, such as the infusion control pump module 500, the liquid heating module 400, and the display module. For example, it precisely regulates the infusion rate to ensure accurate infusion volume; controls the liquid heating module to maintain the infusion fluid at an appropriate temperature; and, when an abnormality is detected, promptly triggers an alarm mechanism and controls the relevant modules to take appropriate actions, thereby ensuring a safe, accurate, and stable infusion process.

[0077] Status indicator area 215: The status indicator area "215" provides medical staff and patients with intuitive device operating status information through different colors and flashing modes. When the device is powered on and all hardware components are initialized normally, the indicator light will be solid green to indicate that the device is in normal operation, informing the user that the device is ready. Once the device detects an abnormality in the infusion process, such as an abnormal liquid flow rate caused by a blockage in the infusion line, the patient's vital signs are outside the safe range, or the communication connection is interrupted, the indicator light will quickly switch to a red flashing mode. This eye-catching prompt method can attract the user's attention in time so that the abnormal situation can be checked and handled as soon as possible. In addition, when the device is connecting wirelessly, the indicator light will also display the communication connection status through a specific flashing frequency, such as fast flashing when connecting, steady flashing when the connection is successful, and special flashing when the connection is interrupted, so that the user can understand the communication status of the device at any time and ensure normal interaction between the device and the external system.

[0078] Operation control panel area 200: The "200" area is the operation control panel of the infusion instrument. The design fully considers the convenience and functionality of human-computer interaction. This area is equipped with a series of ergonomic buttons, knobs, and possible touch-sensitive areas and other operating components. Medical staff or patients can use these operating components to perform various operations on the infusion instrument according to the preset operating logic. Before infusion, key parameters such as infusion speed and infusion volume can be set through buttons or knobs; during infusion, the patient's real-time vital signs data, such as heart rate, blood oxygen, blood pressure, etc., as well as infusion status information such as remaining drug volume, infusion volume, and estimated infusion completion time can be viewed at any time; the device function can also be switched, such as turning on or off the liquid heating function, to meet the different needs of patients for infusion comfort; switching data display mode, choosing to view only infusion-related data, or viewing infusion data and patient vital signs data at the same time, makes it convenient for users to obtain information according to actual needs, greatly improving the convenience of operation and the practicality of the device.

[0079] Infusion line monitoring sensor connection point 510: "510" is the connection point for connecting the sensor that monitors the liquid flow or pressure in the infusion line. The connectable flow sensor or pressure sensor works based on advanced physical sensing principles and can accurately monitor the flow and pressure changes of the liquid in the infusion line in real time. Once it detects that the infusion line is blocked or the liquid flow rate is abnormally too fast or too slow, the sensor will quickly convert the collected data into an electrical signal and transmit it to the main control unit "210" through a specific communication interface. After receiving the data, the main control unit analyzes and judges it based on the preset thresholds and algorithms. Once it determines that an abnormality has occurred, it immediately triggers the corresponding alarm mechanism and controls the infusion control pump module "500" to stop the infusion, effectively avoiding harm to the patient due to abnormal infusion and ensuring the safety of the infusion process.

[0080] Liquid heating module connection point 400: "400" serves as the connection point of the infusion instrument liquid heating module, connecting the heating element and the temperature control sensor. The heating element uses advanced heating technologies, such as resistive heating, induction heating, etc., to accurately heat the infusion liquid according to the instructions issued by the main control unit "210". The temperature control sensor monitors the temperature of the infusion liquid in real time and feeds back the temperature data to the main control unit. The main control unit dynamically adjusts the heating power of the heating element according to the preset target temperature value through a closed-loop control algorithm. For example, when the liquid temperature is lower than the target value, the heating power is increased; when it approaches or reaches the target value, the heating power is reduced to ensure that the infusion liquid stably reaches and maintains a temperature range suitable for patient infusion, effectively improving the patient's comfort during the infusion process and reducing the discomfort caused by low-temperature liquid infusion.

[0081] Infusion container connection interface component 515: "515" connects the infusion device to the infusion bag or bottle. Its design incorporates multiple technical features for a secure and stable connection. Its mechanical structure precisely matches the infusion container interface, ensuring a tight and secure connection and preventing it from falling apart during infusion. The sealing design utilizes special materials and structures to effectively prevent leakage of the infusion liquid, maintaining a clean and safe infusion environment. Furthermore, an air-proof one-way valve or similar device is incorporated to prevent air from entering the infusion line during infusion, eliminating serious medical risks such as air embolism and providing reliable assurance for a smooth infusion process.

[0082] Infusion control pump module 500: "500" is the core component of the infusion instrument that achieves high-precision infusion control. It adopts advanced micro-electromechanical control technology and precision mechanical structure. It accurately adjusts the flow rate and flow rate of the infusion liquid according to the control instructions issued by the main control unit "210". Through the built-in high-precision motor drive system and flow feedback sensor, precise control of the infusion speed is achieved, and the adjustment accuracy can reach 0.01ml. During the infusion process, if an abnormal situation occurs, such as the infusion parameters detected by the sensor deviate too much from the preset value, or the device receives a stop infusion instruction, the infusion control pump module can respond quickly and stop the infusion in time. This precise control capability ensures the safety and accuracy of the infusion process, effectively avoids problems such as adverse drug reactions or poor treatment effects caused by improper infusion speed, and provides reliable protection for patients' infusion treatment.

[0097] The innovative technical features of the "Lingyetong" wristband infusion device of the present invention are mainly reflected in the following aspects:

[0098] 1. Integration of high-precision infusion control and real-time vital signs monitoring: Infusion control accuracy is improved to 0.01ml, and integrated with real-time monitoring of vital signs data such as blood pressure, blood oxygen, and heart rate, which is uncommon in traditional infusion devices. This integrated design requires sophisticated fluid control and sensor technology in hardware, and complex data processing algorithms and vital signs analysis modules in software. The reason why this is not easy to imagine is that achieving such high-precision infusion control requires overcoming technical difficulties in multiple fields such as fluid dynamics, materials science, and electronic engineering. At the same time, real-time monitoring of vital signs data requires precise sensor design and efficient signal processing technology. This is not a conventional technology because it requires interdisciplinary technological innovation and integration. Moreover, achieving such high-precision control and multi-parameter monitoring in a portable device places higher demands on system miniaturization and power consumption control.

[0099] 2. Nanoneedle dermal puncture technology: Using nanoneedles for puncture enables painless infusion. Nanoneedle technology is mostly used in the medical field for drug delivery, cell manipulation, etc. Its application in infusion equipment innovatively solves the problems of pain and infection risks caused by traditional needles. The diameter of the nanoneedle is extremely small, and it causes almost no pain during puncture, and the use of biocompatible materials reduces tissue damage and allergic reactions. This technical point is not easy to think of, mainly because the development and application of nanoneedle technology face multiple challenges such as material preparation, nanoscale processing and biosafety verification, and it is necessary to solve the problem of how to achieve stable liquid transmission at the nanoscale. This is not a conventional technology, because the use of nanoneedles requires the equipment to have extremely high miniaturization and precision manufacturing capabilities, and it is still a cutting-edge exploration in the field of infusion.

[0100] 3. Spectral automatic identification of blood vessels: Spectral analysis technology is used to automatically identify blood vessels, improving the accuracy and success rate of acupuncture and reducing pain for patients. Spectral blood vessel identification technology involves the integrated application of optics, image processing, and machine learning algorithms. It can analyze the spectral characteristics of blood vessels under the skin and accurately locate the blood vessels. The innovation of this technology lies in combining spectral analysis technology with the needs of blood vessel identification and using machine learning algorithms to continuously optimize the recognition accuracy. This is not common in traditional manual or semi-automatic acupuncture devices. It is not easy to think of because it requires deep integration of cross-domain knowledge and extremely high requirements for the real-time and accuracy of the algorithm. This is not a conventional technology because it requires the equipment to be equipped with high-precision light sources, spectral detectors, and powerful data processing capabilities, which are technically difficult to implement on portable devices.

[0101] 4. Integration of encryption technology and blockchain: This technology leverages the advanced encryption technology of the ESP32 chip, combined with blockchain technology to ensure data security. This innovative approach addresses security issues in medical data transmission and storage, preventing the risk of data tampering and privacy leaks. The decentralized and tamper-proof nature of blockchain is highly compatible with the sensitive nature of medical data, ensuring the integrity and authenticity of patient data. This is a daunting task, as integrating blockchain technology into medical device design presents challenges such as technical compatibility, data efficiency, and privacy protection. This is not a conventional approach, as integrating blockchain technology into medical devices is still in its exploratory stages and requires specialized optimization and standardization for specific medical scenarios.

[0102] 5. IoT Integration: Deeply integrate the infusion device with the hospital's IoT system to enable remote monitoring, maintenance, and upgrades. This requires the device to possess stable wireless communication capabilities and seamless integration with the hospital's information system. The application of IoT integration in portable medical devices is notoriously challenging because it requires addressing technical issues such as device power consumption, signal interference, and secure data transmission. This is a non-trivial technique, as IoT integration not only improves device management efficiency but also places higher demands on network compatibility and security.

[0103] 6. Personalized Infusion Plan Recommendations: Based on machine learning algorithms, personalized infusion plan recommendations intelligently recommend the optimal infusion plan based on the patient's physical condition and historical data. This technological innovation lies in its deep integration of artificial intelligence into treatment process management, enhancing the personalization and precision of treatment. The reason this feature may be less obvious is that implementing it requires a vast amount of training data, model optimization, and a deep understanding of medical knowledge. This is unconventional technology, as it represents the development direction of medical decision support systems and has strict requirements for algorithm interpretability, clinical applicability, and ethical compliance.

[0104] 7. User-friendly interface and intelligent voice interaction: An intuitive and easy-to-understand user interface, combined with TTS neural network voice recognition control, enables convenient and intelligent device operation. This innovation significantly lowers the barrier to entry for patients and improves the user experience. The reason this may not be readily apparent is that the application of voice interaction technology in medical devices requires comprehensive consideration of multiple factors, including voice recognition accuracy, noise interference in medical scenarios, and patient privacy. This is not conventional technology, as intelligent voice interaction requires devices with highly sensitive microphones, sophisticated voice recognition algorithms, and powerful data processing capabilities to accurately understand user commands in noisy medical environments.

[0105] 8. Environmentally friendly and energy-saving design: The infusion device utilizes low-power components and optimized energy management to achieve energy conservation and environmental protection. This technological innovation embodies the development concept of green healthcare and reduces the environmental impact of device operation. This is surprising because, while pursuing device performance, long-term energy consumption is not always a primary concern for all designers. This is an unconventional technique, as environmentally friendly design requires not only low power consumption but also consideration of factors such as material recycling and energy consumption during the production process at every stage of the product lifecycle.
