Description

Technical Field

[0001] This invention relates to the field of infusion set technology, specifically an infusion set with a heating function. Background Technology

[0002] Infusion sets are among the most commonly used and basic medical devices in clinical medicine. They are widely used for fluid replenishment, drug therapy, and nutritional support for various patients. With the advancement of medical technology, modern infusion sets have evolved from simple gravity-feed infusions to intelligent infusion pumps with precise flow control, playing an important role in improving drug administration accuracy and ensuring medication safety.

[0003] However, conventional infusion sets still have the following technical shortcomings when dealing with complex environments, special patient groups, and extreme usage scenarios: 1. In cold regions, during winter outdoor emergency rescue, disaster sites, or ambulance transport, low temperatures pose a severe challenge to the normal operation of infusion sets. Low temperatures can cause infusion tubing to harden and lose elasticity, affecting the stability of gravity infusion or pump flow rate. Secondly, some drugs may crystallize or increase in viscosity at low temperatures, affecting their efficacy. Thirdly, direct administration of low-temperature fluids into the patient's body can cause adverse reactions such as vasoconstriction and chills, exacerbating patient discomfort and even inducing complications. 2. Conventional infusion pumps are based on a static planar design, and their flow rate control algorithm assumes that the equipment is in a stable state. However, when infusion is performed in mobile vehicles such as ambulances, helicopters, and ships, the dynamic attitude changes of the equipment, such as tilting, bumping, acceleration and deceleration, will generate additional inertial forces and pressure fluctuations in the liquid in the infusion tube, causing the actual flow rate to deviate from the set value, and even causing safety hazards such as air bubbles mixing in, tube blockage, and false alarms. In summary, existing infusion sets have significant shortcomings in dealing with low-temperature environments and mobile transport, and there is an urgent need for an infusion set with posture self-adaptation and heating functions. Summary of the Invention

[0004] The purpose of this invention is to provide an infusion set with a heating function in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an infusion set with a heating function, comprising: Energy Module: The energy module integrates a solar power supply unit, a hand-cranked power generation unit, and a pluggable universal battery module, and includes an intelligent power management unit for automatically or manually selecting the power source, and prioritizing power supply to preset core functions when the battery is low. Sensing and Execution Module: The sensing and execution module includes an infusion execution unit, a physiological monitoring unit, an environmental and posture sensing unit, and a heating and temperature control unit; The infusion execution unit includes an infusion pump and its drive motor, used to precisely control the infusion flow rate; The physiological monitoring unit includes at least one set of vital sign sensor interfaces for connecting to heart rate, blood oxygen, and blood pressure sensors to obtain the physiological indices of the injured person. The environment and attitude sensing unit includes an inertial measurement unit (IMU) for real-time sensing of the device's motion attitude and bump status. The heating temperature control unit includes a heating element and a temperature sensor embedded in the outer casing, used to maintain the outer casing temperature at a preset value; Information processing and communication module: The information processing and communication module includes a central processing unit (CPU), a local storage unit, a casualty information identification unit, a satellite positioning unit, and a wireless communication unit; Central Control Unit: The central control unit is electrically connected to the energy module, infusion execution unit, physiological monitoring unit, environmental and attitude sensing unit, heating temperature control unit, and information processing and communication module, and is configured as follows: Based on the data from the environment and attitude sensing unit, the driving parameters of the infusion execution unit are dynamically adjusted; Based on the data from the physiological monitoring unit, when it is determined that the patient has signs of shock, the infusion rate of the infusion execution unit is automatically adjusted. The heating temperature control unit is controlled to perform closed-loop regulation of the shell temperature, and the information processing and communication module is coordinated to perform wounded personnel information binding, data encryption storage, location tracking and wireless data transmission.

[0006] As a further aspect of the present invention, the central control unit is further configured to: when the wireless communication unit detects a network interruption, automatically store the data temporarily in the local storage unit, and resume transmission after the network is restored.

[0007] As a further aspect of the present invention: the outer shell of the infusion set is made of a smooth material that is resistant to salt spray, moisture, and corrosion, and the interfaces of the infusion execution unit and the energy module are designed as modular structures that can be quickly disassembled and assembled without tools.

[0008] As a further aspect of the present invention, the infusion set also includes a human-computer interaction module, which has a silent operation mode in which all sound prompts are disabled and all visible light sources are switched to a low visibility state compatible with night vision devices.

[0009] As a further aspect of the present invention, the human-computer interaction module also includes a vibration motor, which provides information prompts through vibration in silent operation mode.

[0010] As a further aspect of the present invention: when the central control unit determines that the device is in a bumpy state based on the data from the inertial measurement unit, it automatically increases the sensitivity thresholds for bubble detection and pipeline blockage detection.

[0011] As a further aspect of the present invention: the casualty information identification unit is an RFID reader or a QR code scanning module, used to read and associate electronic casualty ticket information.

[0012] As a further aspect of the present invention: the satellite positioning unit is a GPS or Beidou positioning module, used to record the location and time information of key treatment nodes, and stored together with physiological data in the local storage unit.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating a sensing and execution module that includes an infusion execution unit, a physiological monitoring unit, an environmental and posture sensing unit, and a heating and temperature control unit, the system achieves active heating in low-temperature environments and precise infusion control during movement. Heating elements and temperature sensors are embedded in the outer casing, and closed-loop control maintains the casing temperature at a constant 37°C. This offers significant advantages in cold regions, winter outdoor emergency care, and ambulance transport scenarios. A high-precision inertial measurement unit continuously senses the device's tilt, bumps, acceleration, and deceleration. When the system detects severe bumps or tilting, it dynamically adjusts the infusion pump's drive control parameters and simultaneously increases the sensitivity thresholds for bubble detection and tubing blockage detection. This effectively compensates for the additional inertial forces and pressure fluctuations in the infusion tubing caused by changes in posture, ensuring the actual flow rate remains stable near the set value and preventing false alarms caused by changes in body position. 2. Through a closed-loop response mechanism for vital signs, intelligent linkage between infusion rate and patient physiological state is achieved, transforming the infusion set from a passive execution device into an intelligent terminal that actively participates in treatment. The physiological monitoring unit receives real-time vital sign data such as heart rate, blood oxygen, and blood pressure, and runs a preset shock judgment model in the central control unit. When the comprehensive judgment result reaches the shock warning threshold (such as low heart rate, decreased blood oxygen saturation, and sudden drop in blood pressure at the same time), the system automatically generates a control command to adjust the infusion pump flow rate to the preset emergency mode flow rate, achieving a second-level response of "perception-decision-execution". This buys golden time for the rescue of critical situations such as hemorrhagic shock and significantly improves treatment efficiency. 3. By integrating a solar power supply unit, a hand-cranked power generation unit, and a pluggable universal battery module, and dynamically scheduling them through an intelligent power management unit, the system offers several advantages. First, in remote areas or disaster zones without grid coverage, it can utilize solar energy or manual hand-cranking for emergency charging, preventing equipment failure due to battery depletion. Second, when the total power level falls below a preset threshold, the system automatically cuts off power to non-core functions (such as data upload and high-brightness display), prioritizing the operation of the infusion pump, vital sign monitoring, and alarm modules. This effectively solves the problems of single energy supply and insufficient battery life in traditional portable infusion devices, providing reliable support for long-distance transport and continuous treatment in extreme environments. 4. By setting up a wounded information identification unit (RFID / QR code scanning), a satellite positioning unit (GPS / BeiDou), and a wireless communication module (Mesh self-organizing network), the entire medical data chain from the scene to the hospital is ensured to be complete and traceable, providing continuous and accurate decision-making basis for subsequent diagnosis and treatment, which is in line with the modern medical concept of "information accompaniment". 5. Through the silent operation mode setting of the human-computer interaction module, the system turns off all sound prompts and adjusts all visible light sources to low illumination or infrared spectrum compatible with night vision equipment. At the same time, the vibration motor is used as the main feedback means. It has obvious advantages in night wards, home night care or rescue sites that need to be quiet: it does not affect the patient's rest or interfere with the order of the scene, while meeting the requirements of low detectability of the equipment in special scenarios.

[0017] Please see Figures 1 to 4 In this embodiment of the invention, an infusion set with a heating function includes: Energy Module: The energy module integrates a solar power supply unit, a hand-cranked generator unit, and a pluggable universal battery module, and includes an intelligent power management unit for automatically or manually selecting the power source, and prioritizing power supply to preset core functions when the battery is low.

The environment and attitude sensing unit includes an inertial measurement unit (IMU) for real-time sensing of the device's motion attitude and turbulence status. The heating temperature control unit includes a heating element and a temperature sensor embedded in the housing, used to maintain the housing temperature at a preset value; Information processing and communication module: The information processing and communication module includes a central processing unit (CPU), a local storage unit, a casualty information identification unit, a satellite positioning unit, and a wireless communication unit; Central Control Unit: The central control unit is electrically connected to the energy module, infusion execution unit, physiological monitoring unit, environmental and attitude sensing unit, heating and temperature control unit, and information processing and communication module, and is configured as follows: Based on data from the environment and attitude sensing unit, the driving parameters of the infusion execution unit are dynamically adjusted; Based on data from the physiological monitoring unit, when the patient is judged to have signs of shock, the infusion rate of the infusion execution unit is automatically adjusted. The heating temperature control unit is used to perform closed-loop regulation of the shell temperature, and the information processing and communication module is coordinated to bind casualty information, encrypt and store data, locate and track locations, and transmit wireless data. The central control unit is also configured to automatically store data in the local storage unit when the wireless communication unit detects a network interruption, and resume transmission after the network is restored. When the central control unit determines that the equipment is in a bumpy state based on the data from the inertial measurement unit, it automatically increases the sensitivity threshold for bubble detection and pipeline blockage detection. The infusion set also includes a human-machine interface module with a silent operation mode in which all sound prompts are disabled and all visible light sources are switched to a low visibility state compatible with night vision devices. The human-computer interaction module also includes a vibration motor, which provides information prompts through vibration in silent operation mode; The casualty information identification unit is an RFID reader or a QR code scanning module, used to read and associate electronic casualty ticket information; The satellite positioning unit is a GPS or BeiDou positioning module, used to record the location and time information of key treatment nodes, and stored together with physiological data in the local storage unit.

[0018] In this embodiment, the control method and steps for this infusion set are as follows: Step S1, Intelligent Energy Scheduling: The intelligent power management unit (PMU) monitors the energy status of the solar power supply unit, the hand-cranked generator unit, and the replaceable universal battery module in real time. Based on preset priority rules or external commands, it automatically switches and allocates power supply paths. At the same time, it monitors the total power of the system. When the power is lower than the first threshold, it cuts off the power supply to non-core functional modules and only maintains the operation of the infusion actuator, core sensors, and alarm modules. Step S2, Environmental and Attitude Adaptive Adjustment: The attitude and motion data of the infusion set device are acquired in real time through the inertial measurement unit (IMU), and the data is processed and analyzed. If it is determined that the device is in a state of severe shaking or tilting, the drive control parameters of the infusion pump are dynamically adjusted, and the sensitivity thresholds of bubble detection and tubing blockage detection are increased simultaneously. The temperature of the infusion set device is fed back in real time by the outer shell temperature sensor. When the outer shell temperature is detected to be lower than 37°C, the heating element is activated to perform closed-loop control to keep the outer shell temperature constant at 37°C. Step S3: Closed-loop response of vital signs: Receive vital sign data such as heart rate, blood oxygen saturation, and blood pressure in real time through the physiological monitoring unit, and run the preset shock judgment model; When the comprehensive judgment results reach the shock warning threshold, a control command is automatically generated to adjust the flow rate of the infusion pump to the preset emergency mode flow rate. Step S4: Information Accompaniment and Adaptive Transmission: Read and bind the patient's electronic injury ticket information via RFID or barcode scanning module; It periodically records vital signs data, infusion parameters, and alarm events, and associates them with the location and timestamp obtained by the satellite positioning unit. The data is then encrypted and stored in the local memory. At the same time, it attempts to connect to the network via the wireless communication module. If the network is available, it uploads the data to the remote terminal in real time. If the network is interrupted, the data is temporarily stored and automatically resumed after the network is restored. Step S5: Switching between Human-Computer Interaction and Stealth Mode: Upon receiving the mode switching command, when switching to silent operation mode, all sound prompts are turned off, and all visible light sources are adjusted to low illumination or infrared spectrum compatible with night vision equipment. At the same time, the vibration motor is enabled as the main feedback means.

[0019] Please refer to this carefully. Figure 1 The infusion set's outer shell is made of a smooth material that is resistant to salt spray, moisture, and corrosion. The interfaces of the infusion execution unit and the energy module are designed as modular structures that allow for quick assembly and disassembly without tools.

[0020] In this embodiment, the outer shell, made of salt spray-resistant, moisture-resistant, and corrosion-resistant materials, can adapt to complex outdoor environments. The modular design allows for quick assembly and disassembly, facilitating rapid maintenance or component replacement during outdoor rescue operations, reducing the total life-cycle cost of the equipment, and meeting hygiene requirements after intensive use.
