Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a wearable intelligent emergency rescue device. Background Technology

[0002] With the accelerating aging of society and the rising incidence of acute illnesses such as cardiovascular diseases, traditional emergency care models are struggling to fully cover sudden health risks. Against this backdrop, wearable smart emergency devices have emerged, aiming to continuously monitor users' vital signs, automatically identify dangers and initiate emergency responses in the event of sudden illness or accident, transforming the traditional passive approach to help into proactive and rapid intelligent life protection.

[0003] The existing product, the ZOLL LifeVest wearable defibrillator, is used for the prevention of out-of-hospital cardiac arrest in high-risk patients. Patients wear a vest-style fabric vest with sensing electrodes close to their body, and the treatment module (containing the battery and defibrillator) is connected via wires and placed in a waist pack. The device continuously monitors ECG signals. When it detects a life-threatening arrhythmia that meets the treatment criteria, it first issues an alarm. If the patient does not respond and press the button to stop within a specified time, the device will automatically deliver an electric shock to the patient's chest to defibrillate.

[0004] However, the aforementioned products use limited preset sizes, and their fit relies on traditional Velcro or elastic bands for rough manual adjustment. For patients whose body shape is on the edge of the standard range or with special body postures, it is difficult to achieve a stable and comfortable personalized close fit. This imperfect fit can lead to increased motion artifacts and drift or errors in vital sign data. Therefore, it is necessary to propose a wearable intelligent emergency rescue device to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a wearable intelligent emergency rescue device that dynamically adjusts the fit and pressure of the monitoring component based on the patient's real-time body shape data. This ensures stable and uniform electrical contact between the monitoring component and the skin surface, reduces electrode displacement caused by changes in body position, and ensures that the device can be stably fixed to the patient's body surface after dynamic adjustment, forming a reliable monitoring interface.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A wearable intelligent emergency rescue device includes a controller and an open ring-shaped main body, the ring-shaped main body being composed of a support area, several adjustment areas and a monitoring area; wherein, both sides of the support area are fixedly connected to the adjustment area, and the side of the adjustment area away from the support area is fixedly connected to the monitoring area.

[0007] The ring-shaped body is equipped with a fastening assembly for quickly fixing the sides of the ring-shaped body, and the fastening assembly is connected to the controller signal.

[0008] The ring-shaped main body is equipped with a body shape recognition module for identifying the patient's body shape, and the body shape recognition module is connected to the controller signal.

[0009] A support frame is fixedly connected to the inner wall of the adjustment area near the support area. Several staggered first rods are hinged to one side wall of the support frame. Second rods are hinged to both ends of each first rod, with adjacent second rods being staggered. Third rods are hinged to the ends of each second rod furthest from the first rod, with adjacent third rods furthest from the second rods hinged to each other. The first, second, and third rods all rotate with the inner wall of the adjustment area. A drive assembly is provided on the support frame to drive the first, second, and third rods to move closer or wider, and this drive assembly is connected to the controller. A monitoring assembly is provided in the monitoring area to monitor the patient's vital signs, and this monitoring assembly is also connected to the controller.

[0010] The technical principles of the above solution are as follows:

[0011] The body shape recognition module acquires the patient's body shape data. Based on the body shape data, the controller controls the drive components to work, causing the first, second, and third hinged rods to extend or contract in unison, which in turn causes the adjustment area and the monitoring area to expand or contract as a whole, thereby automatically adapting to the torso contours of different patients. After the monitoring components are tightly fitted to the ring-shaped main body, they collect vital sign data in real time. The fastening components ensure that the device can be stably fixed to the patient's body surface after dynamic adjustment, forming a reliable monitoring interface.

[0012] The above approach has the following beneficial effects:

[0013] 1. This solution, through the synergistic action of the body shape recognition module and the driving components, can automatically identify the patient's body contour and drive the adjustment area to undergo three-dimensional deformation, enabling the monitoring components within the monitoring area to form a uniform, tight, and comfortable personalized fit with the body surface. This dynamically adaptive tight fit significantly reduces motion artifacts caused by device displacement or loosening, and lowers signal drift or errors due to uneven contact pressure.

[0014] 2. Traditional fixed-size and manual adjustment methods can easily cause local pressure or loosening in patients with special body types. However, the adaptive adjustment in this solution uses the coordinated deformation of distributed hinge rods to evenly distribute the pressure of the ring body on the body surface, avoiding excessive pressure at a single point. Moreover, it can provide a stable and personalized fit for patients of different body types, including standard borderline body types and special body postures, without the need for repeated manual adjustments.

[0015] 3. This solution achieves rapid personalized adaptation through an adaptive process, reducing adjustment time caused by improper wearing. The continuously optimized fit also ensures the long-term stability of monitoring data, providing clinicians with continuous and reliable vital sign records and assisting doctors in more accurately assessing changes in patients' conditions and treatment effectiveness.

[0016] Furthermore, the fastening assembly includes a magnet and a magnetic induction unit that are fixedly connected to both ends of the ring-shaped body and cooperate with each other; the magnetic induction unit is signal-connected to the controller and is used to generate an electrical signal of the fastening state when the magnet and the magnetic induction unit are aligned and attracted, and the controller activates the body shape recognition module based on the electrical signal.

[0017] Beneficial effects: The magnetic alignment enables rapid closure and automatically triggers subsequent processes. When the magnet and the magnetic induction unit are accurately attracted, the controller generates an immediate confirmation signal and activates the body shape recognition module based on the signal, ensuring that the device starts the adaptive adjustment process the moment it is put on. This eliminates the alignment and operation steps of traditional mechanical fasteners, improving the ease of wearing, and the electrical confirmation mechanism ensures the reliability of the device's initial state, laying the foundation for subsequent accurate monitoring and adjustment.

[0018] Furthermore, the body shape recognition module includes a pressure sensor array fixedly connected to the monitoring area and a distance sensor array fixedly connected to the support area and the monitoring area. Both the pressure sensor array and the distance sensor array are connected to the controller signal.

[0019] The system includes a distance sensor array for measuring the distance between the ring-shaped main body and the patient's body surface; a pressure sensor array for monitoring the contact pressure distribution between the inner wall of the ring-shaped main body and the patient's body surface; a body shape recognition module for fusing distance information and contact pressure distribution information to generate the patient's body shape parameters and assess fit; and a controller for issuing adjustment commands to the drive components based on the body shape parameters and fit assessment results.

[0020] Beneficial effects: By fusing distance information from the range sensor array with contact pressure distribution information from the pressure sensor array, the body shape recognition module can construct a three-dimensional contour and pressure map of the patient's body surface, thereby generating quantified body shape parameters and evaluating fit quality in real time.

[0021] Furthermore, the drive assembly includes a sprocket with a conveyor chain meshing at its bottom; a guide rail that mates with the sprocket is provided at the top of the support frame, and the sprocket slides along the guide rail; the conveyor chain is located on the inner side wall of the support frame and slides with the support frame; a motor for driving the conveyor chain to rotate is fixedly connected to the side wall of the support frame; a connecting rod is coaxially fixedly connected to the sprocket, and the other end of the connecting rod passes through the intersection with the adjacent second rod and rotates with the second rod.

[0022] Beneficial effects: The motor drives the transmission chain to drive the sprocket to move synchronously. The sprocket converts the rotation into the pushing and pulling action of the second rod through the connecting rod, which in turn links the multi-level hinge structure formed by the first and third rods to achieve synchronous and proportionally coordinated deformation of the adjustment area. This allows the ring body to quickly adapt to the body contours of different patients and ensures that the monitoring area and the treatment electrode always maintain the preset orientation and pressure distribution during the adjustment process.

[0023] Furthermore, the monitoring components include a temperature sensor, a bioimpedance sensor, and several photoelectric sensors. The temperature sensor is fixedly connected to the outer wall of the monitoring area and is used to acquire the patient's axillary temperature data and transmit the temperature data to the controller. The bioimpedance sensor includes several pairs of excitation electrodes and measuring electrodes. The excitation electrodes are fixedly connected to the left anterior side of one monitoring area and the right posterior side of another monitoring area, and the measuring electrodes are fixedly connected to the right anterior side of one monitoring area and the left posterior side of another monitoring area. The bioimpedance sensor is used to acquire the impedance of the patient's pleural cavity, and obtains the patient's respiratory rate data and pleural effusion data through impedance changes, transmitting the respiratory rate data and pleural effusion data to the controller. The photoelectric sensors are symmetrically fixedly connected to the inner wall of the monitoring area near the adjustment area. The photoelectric sensors are used to acquire the patient's heart rate data and blood oxygen saturation data, transmitting the heart rate data and blood oxygen saturation data to the controller.

[0024] Beneficial effects: The monitoring component achieves continuous acquisition of vital signs through distributed multi-sensor fusion; the temperature sensor locates the axillary region to obtain stable body temperature data; the photoelectric sensor captures heart rate and blood oxygen saturation parameters in real time; the bioimpedance sensor adopts a diagonal electrode layout across the thoracic cavity to simultaneously extract the periodic changes in pleural impedance caused by respiratory rhythm and the impedance baseline shift caused by pathological effusion, integrating respiratory rate monitoring and early warning functions for pleural effusion.

[0025] Furthermore, it also includes a hospital information system; the hospital information system includes: an electronic health record module, which stores patients' historical medical records; an emergency plan database, which stores multiple emergency plans; and a monitoring module, which receives and displays real-time vital signs data and emergency plans.

[0026] Beneficial effects: The hospital information system can automatically compare the patient's historical medical records with the current data in the electronic health record module, quickly retrieve the most suitable individualized treatment plan from the emergency plan database, realize an integrated closed loop from on-site monitoring, data transmission, historical review to plan guidance, shorten the information gap between inside and outside the hospital and decision-making delay, and improve emergency efficiency and treatment accuracy.

[0027] Furthermore, it also includes a communication early warning system integrated within the ring-shaped main body; wherein, the communication early warning system includes: a hospital intranet communication module, used to establish a data connection with the hospital information system; and an early warning module, used to analyze the vital sign data collected by the monitoring components and determine whether any abnormalities have occurred.

[0028] Beneficial effects: The hospital intranet communication module enables real-time synchronization of monitoring data with the hospital information system, allowing the hospital's medical team to remotely and continuously track patients' vital signs and establish a direct link between pre-hospital early warning and in-hospital response; the early warning module, based on real-time data analysis, can automatically trigger graded early warning prompts when it detects data patterns that meet clinical abnormality criteria, thereby transforming the traditional passive response into early proactive intervention, shortening clinical decision-making time, and securing more timely professional treatment opportunities for high-risk patients.

[0029] Furthermore, when the early warning module determines that an abnormality has occurred, it generates an alarm message and simultaneously initiates a query to the electronic health record module to obtain the patient's allergy history and key past medical history information. The obtained allergy history and key past medical history information are included in the alarm message and sent to the hospital information system through the hospital intranet communication module. The emergency plan database in the hospital information system receives the alarm message, matches and retrieves the corresponding emergency plan, and sends the emergency plan to the monitoring module.

[0030] Beneficial effects: When the early warning module determines that a patient is abnormal, it automatically triggers an alarm and immediately links with the electronic health record module to obtain the patient's allergy history and key past medical history information. This information is integrated into the alarm content and transmitted to the hospital information system through the hospital intranet communication module. The system then matches and calls up the corresponding emergency plan and sends it directly to the monitoring module. This achieves an automated closed loop from risk identification and key information integration to emergency plan scheduling, shortening clinical response time, avoiding delays or omissions that may occur due to manual inquiries, and ensuring that the emergency team has a grasp of the patient's core medical background before intervention, thereby improving the accuracy and safety of emergency care.

[0031] Furthermore, the hospital intranet communication module supports at least one of the protocols including Wi-Fi, Bluetooth, or Zigbee, and interacts with the hospital information system for data exchange.

[0032] Beneficial effects: The hospital intranet communication module supports multiple wireless protocols, enabling stable data interaction between the hospital information system and ensuring that patients' vital signs data are synchronized to the hospital information system in real time and automatically, providing continuous and reliable monitoring data for clinical decision-making.

[0033] Furthermore, a function button is fixedly connected to the ring-shaped main body. The function button is connected to the controller signal, and the controller signal is connected to a high-voltage isolation protection circuit. The high-voltage isolation protection circuit includes an electrical isolation switch connected in series with the magnetic induction unit, temperature sensor, bioimpedance sensor, and several photoelectric sensors. When entering the emergency mode, the controller controls the electrical isolation switch to open, so that the patient's skin is electrically isolated from the magnetic induction unit, temperature sensor, bioimpedance sensor, and several photoelectric sensors.

[0034] Beneficial effects: When the device enters emergency defibrillation mode, the controller disconnects the electrical isolation switch, electrically isolating the magnetic induction unit, temperature sensor, bioimpedance sensor, and photoelectric sensor from the patient's skin. This prevents the therapeutic high-voltage shock energy from flowing back into the precision sensors and main control circuit, avoiding damage to sensitive components from high-voltage pulses. At the same time, it eliminates the instantaneous impact of common-mode interference on vital sign monitoring signals, ensuring that the monitoring components can quickly resume stable operation after defibrillation treatment, and guaranteeing safety and data continuity throughout the entire emergency process.

[0044] The following detailed description illustrates the specific implementation method:

[0045] Example 1:

[0046] As attached Figure 1 As shown: A wearable intelligent emergency rescue device includes a controller and an open ring-shaped body 1. The ring-shaped body 1 is composed of a support area 4, several adjustment areas 3 and a monitoring area 2. The two sides of the support area 4 are fixedly connected to the adjustment areas 3, and the side of the adjustment area 3 away from the support area 4 is fixedly connected to the monitoring area 2.

[0047] The annular body 1 is provided with a fastening assembly for quickly fixing the side of the annular body 1, and the fastening assembly is connected to the controller signal.

[0048] The ring-shaped main body 1 is equipped with a body shape recognition module for recognizing the patient's body shape, and the body shape recognition module is connected to the controller signal.

[0049] like Figure 3 and Figure 4 As shown, a support frame 10 is fixedly connected to the inner wall of the adjustment area 3 near the support area 4, as follows: Figure 2As shown, a number of staggered first rods 15 are hinged to one side wall of the support frame 10; each end of the first rod 15 is hinged to a second rod 16, and adjacent second rods 16 are staggered; each end of the second rod 16 away from the first rod 15 is hinged to a third rod 17, and adjacent third rods 17 are hinged to each other at the ends away from the second rod 16; the first rod 15, the second rod 16 and the third rod 17 are all rotatably engaged with the inner side wall of the adjustment area 3; the support frame 10 is provided with a drive assembly for driving the first rod 15, the second rod 16 and the third rod 17 to move closer or expand, and the drive assembly is signal-connected to the controller.

[0050] The fastening assembly includes a magnet and a magnetic sensing unit that are fixedly connected to both ends of the annular body 1 and cooperate with each other. The magnetic sensing unit is signal-connected to the controller and is used to generate an electrical signal indicating the fastening state when the magnet and the magnetic sensing unit are aligned and attracted. The controller then activates the body shape recognition module based on this electrical signal. In this embodiment, the magnet is a neodymium iron boron magnetic ring, and the magnetic sensing unit is a Hall sensor.

[0051] Specifically, medical staff wear the ring-shaped main body 1 on the patient's chest and abdomen. The neodymium iron boron magnetic rings at both ends automatically attract and align with the Hall sensor under the action of magnetic force. The Hall sensor senses the magnetic field strength and outputs an electrical signal. This electrical signal is sent to the controller as a digital instruction that the device has been correctly worn. After receiving the electrical signal, the controller sends an initialization command to the body shape recognition module, starts its workflow, and begins to automatically collect the patient's body shape parameters.

[0052] like Figure 1 As shown, the body shape recognition module includes a pressure sensor array 9 fixedly connected to the monitoring area 2 and a distance sensor array fixedly connected to the support area 4 and the monitoring area 2. Both the pressure sensor array 9 and the distance sensor array are connected to the controller signal.

[0053] Among them, the distance sensor array is used to measure the distance between the ring body 1 and the patient's body surface; the pressure sensor array 9 is used to monitor the contact pressure distribution between the inner wall of the ring body 1 and the patient's body surface; the body shape recognition module is used to fuse distance information and contact pressure distribution information to generate the patient's body shape parameters and evaluate the fit; the controller sends adjustment commands to the drive components based on the body shape parameters and fit evaluation results.

[0054] Specifically, after the garment is fastened, the range sensor array distributed in the support area 4 and monitoring area 2 is activated first, emitting infrared laser signals to measure the distances from the inner wall of the annular body 1 to multiple points on the patient's back, side chest, and anterior chest surface, outlining the initial body contour. Simultaneously, the pressure sensor array 9 synchronously collects the initial contact pressure distribution between each contact point and the skin. The controller receives and integrates these two sets of information in real time, calculates key parameters such as the circumference and curvature that characterize the body shape, and assesses the current fit based on the pressure distribution, identifying areas of excessive pressure or poor contact. Based on the generated body shape parameters and fit assessment results, the controller determines the areas and magnitudes requiring adjustment and sends instructions to the drive component. The drive component changes the tension and local curvature of the annular body 1 through extension and contraction, achieving three-dimensional fit adjustment, continuously fine-tuning until the pressure distribution is uniform and stable within the ideal range, thus providing a contact basis for subsequent vital sign monitoring.

[0055] like Figure 4 As shown, the drive assembly includes a sprocket 11, with a conveyor chain 13 meshing at its bottom; a guide rail is provided at the top of the support frame 10 to cooperate with the sprocket 11, and the sprocket 11 slides along the guide rail; the conveyor chain 13 is located on the inner wall of the support frame 10 and slides with the support frame 10; a motor 14 for driving the conveyor chain 13 to rotate is fixedly connected to the side wall of the support frame 10; as shown Figure 2 As shown, a connecting rod 12 is coaxially fixedly connected to the sprocket 11. The other end of the connecting rod 12 passes through the intersection with the adjacent second rod 16 and is rotatably engaged with the second rod 16. In this embodiment, the transmission chain 13 consists of two drive wheels and a chain, and the output shaft of the motor 14 is coaxially fixed with one of the drive wheels.

[0056] Specifically, when the controller issues an adjustment command, the motor 14 starts, and its output shaft drives the drive wheel to rotate, causing the chain meshed with it to slide along the inner wall of the support frame 10. For example, as Figure 4 As shown, when the output shaft of motor 14 rotates clockwise, the transmission chain 13 consisting of the drive wheel and the chain rotates clockwise as a whole. Since the bottom of the sprocket 11 only engages with the chain, when the chain rotates clockwise, its lower part moves to the left. Under this leftward trend, the sprocket 11 rotates clockwise and moves to the right (the first rod 15, the second rod 16 and the third rod 17 are all made of lightweight materials, and their weight will not affect the movement of the sprocket 11).

[0057] like Figure 2As shown, since the sprocket 11 and the connecting rod 12 are coaxially fixedly connected, the connecting rod 12 rotates with the sprocket 11 and pushes the second rod 16, which is in tandem with it, to move in the same direction. For example, when the second rod 16 moves to the right, the first rod 15 and the third rod 17, which are interlocked with it, move in tandem. The entire mesh support, consisting of the interlocked first rod 15, the second rod 16, and the third rod 17, begins to deform. The hinge points between the rods move outward, causing the inner wall of the entire adjustment area 3 to expand outward, thereby relaxing the restraint on the patient's body. During this process, since the top of the support frame 10 is provided with a guide rail that mates with the sprocket 11, the sprocket 11 slides along the guide rail. Therefore, when the sprocket 11 moves, the guide rail can limit and guide the movement of the sprocket 11.

[0058] When tightening is required, the controller instructs motor 14 to rotate in the opposite direction, causing the chain to slide in the opposite direction. This pulls the second rod 16 in the opposite direction via sprocket 11 and connecting rod 12. The movement of the second rod 16 then drives the first rod 15 and the third rod 17 in the opposite direction, causing the entire mesh support to contract inward. This pulls the inner wall of the adjustment area 3 inward, increasing the pressure on the body. After motor 14 stops rotating, the self-locking effect of the drive wheel and chain locks the adjustment state, maintaining the current tension until the next adjustment command is received.

[0059] Monitoring area 2 is equipped with a monitoring component for monitoring the patient's vital signs, and the monitoring component is connected to the controller signal. For example... Figure 1 As shown, the monitoring component includes a temperature sensor 8, a bioimpedance sensor, and several photoelectric sensors 5. The temperature sensor 8 is fixedly connected to the outer wall of the monitoring area 2 and is used to acquire the patient's axillary temperature data and transmit the temperature data to the controller. The bioimpedance sensor includes several pairs of excitation electrodes 6 and measuring electrodes 7. The excitation electrodes 6 are fixedly connected to the left anterior side of one monitoring area 2 and the right posterior side of another monitoring area 2, and the measuring electrodes 7 are fixedly connected to the right anterior side of one monitoring area 2 and the left posterior side of another monitoring area 2. The bioimpedance sensor is used to acquire the impedance of the patient's pleural cavity, and by measuring the impedance changes, acquire the patient's respiratory rate data and pleural effusion data, transmitting these data to the controller. The photoelectric sensors 5 are symmetrically fixedly connected to the inner wall of the monitoring area 2 near the adjustment area 3. The photoelectric sensors 5 are used to acquire the patient's heart rate data and blood oxygen saturation data, transmitting these data to the controller.

[0060] Specifically, after the adaptive adjustment is completed, all sensors in monitoring area 2 start working synchronously.

[0061] Among them, the symmetrically arranged photoelectric sensors 5 emit light of specific wavelengths, such as red light and infrared light, to irradiate subcutaneous capillaries. By detecting the periodic changes in the intensity of reflected light, the raw waveform data of heart rate and blood oxygen saturation are acquired in real time. The purpose of symmetrically fixing the photoelectric sensors 5 to the inner wall of the monitoring area 2 near the adjustment area 3 is that this area corresponds to the two sides of the thorax, near the mid-axillary line. The chest wall is thinner here and it is close to the branches of the axillary artery, with abundant arteries. With the heartbeat, the arterial blood volume changes periodically, making it easier to obtain the periodic changes in light absorption.

[0062] Meanwhile, the temperature sensor 8, fixed to the outer wall of the monitoring area 2, is closely attached to the armpit area to continuously measure the body surface temperature.

[0063] A pair of excitation electrodes 6 of the bioimpedance sensor injects a safe high-frequency microcurrent into the pleural cavity, and a pair of measuring electrodes 7 detect the voltage difference, thereby obtaining the original impedance signal reflecting the change in pleural cavity volume.

[0064] The raw data collected by each sensor is transmitted to the controller in real time. The controller processes the raw data; extracts the peak interval and amplitude ratio of the pulse wave from the signal transmitted by photoelectric sensor 5, and calculates the heart rate and blood oxygen saturation percentage; filters the bioimpedance signal and extracts its periodic low-frequency component, which is the respiratory rate, and analyzes the baseline value or trend of impedance to assess the risk of pleural effusion; the data from temperature sensor 8 is converted into body temperature readings after calibration.

[0065] like Figure 5 As shown, it also includes a hospital information system; wherein, the hospital information system includes;

[0066] The electronic health record module stores patients' historical medical records.

[0067] Emergency response plan database, storing multiple emergency response plans.

[0068] The monitoring module receives and displays real-time vital signs data and emergency response plans.

[0069] like Figure 5 As shown, it also includes a communication early warning system integrated within the ring-shaped main body 1; wherein, the communication early warning system includes:

[0070] The hospital intranet communication module is used to establish a data connection with the hospital information system. The module supports at least one of the following protocols: Wi-Fi, Bluetooth, or Zigbee, and interacts with the hospital information system.

[0071] The warning module is used to analyze the vital sign data collected by the monitoring component and determine whether an abnormality occurs. When the warning module determines that an abnormality has occurred, it generates an alarm message and simultaneously initiates a query to the electronic health record module to obtain the patient's allergy history and key past medical history information. The obtained allergy history and key past medical history information are included in the alarm message and sent to the hospital information system through the hospital intranet communication module; the emergency plan library in the hospital information system receives the alarm message, matches and retrieves the corresponding emergency plan, and sends the emergency plan to the monitoring module.

[0072] Specifically, the warning module analyzes the real-time vital sign data uploaded by the monitoring component to determine whether an abnormality occurs. When an abnormality occurs, the warning module immediately starts a composite response: on the one hand, it generates an alarm message containing the type of abnormality, time, and real-time data; on the other hand, through the hospital intranet communication module, it automatically initiates a targeted query to the electronic health record module to obtain the patient's drug allergy history, key past medical history such as heart failure, COPD and other background information, and integrates these key medical histories into the alarm message.

[0073] The alarm message is simultaneously pushed to the hospital information system through the hospital intranet communication module; the hospital information system triggers a two-level linkage: the emergency plan library intelligently matches the most relevant standardized emergency procedure from the emergency plan library according to the type of abnormality in the alarm message such as ventricular fibrillation, and the patient medical history label such as coronary heart disease; the monitoring module then receives and highlights the alarm message, the integrated vital sign trend chart, and the matched emergency plan in real time. Finally, the decision-making information integrating the alarm message, the vital sign trend chart, and the emergency plan is synchronously pushed to the nurse station, the doctor's mobile terminal, and the central monitoring large screen.

[0074] In this embodiment, the magnetic snap is used to trigger body shape recognition and adaptive adjustment. The driving component is used to continuously adjust the three-dimensional fitting degree of the annular main body 1 to the patient's chest and abdomen, and at the same time, the vital signs are collected by the monitoring component. When an abnormality is detected, the communication warning system automatically associates the patient's historical medical records and retrieves the standardized emergency plan, forming a complete closed-loop first aid from intelligent wearing, continuous monitoring to warning.

[0075] Embodiment 2:

[0076] The difference from Embodiment 1 is that a function button (not shown in the figure) is fixedly connected to the annular main body 1, and the function button is signal-connected to the controller; the controller is also signal-connected to a high-voltage isolation protection circuit, and the high-voltage isolation protection circuit includes an electrical isolation switch connected in series with the magnetic induction unit, the temperature sensor 8, the bio-impedance sensor, and several photoelectric sensors 5. When entering the first aid mode, the controller controls the electrical isolation switch to disconnect, so that the patient's skin is electrically isolated from the magnetic induction unit, the temperature sensor 8, the bio-impedance sensor, and several photoelectric sensors 5.

[0077] Specifically, when entering emergency mode, for example, when preparing for defibrillation, medical personnel press and hold the function button for more than 3 seconds. The controller recognizes this as a command to trigger emergency isolation and immediately sends a command to the high-voltage isolation protection circuit. The electrical isolation switch disconnects the electrical connection between the magnetic induction unit, temperature sensor 8, bioimpedance sensor, and photoelectric sensor 5, which are in contact with the patient's skin. When the magnetic induction unit is disconnected, the two ends of the ring body 1 are released, exposing the patient's chest and abdomen for subsequent defibrillation. All the aforementioned sensors are also disconnected to ensure that during high-energy electric shock treatments such as defibrillation, strong instantaneous currents cannot pass through the sensor circuits, preventing abnormal shunting or damage to precision electronic components. Simultaneously, the controller's own circuit remains powered and operational to maintain critical safety functions such as communication until the emergency mode is deactivated. Afterward, the controller will re-close the electrical isolation switch, and medical personnel can then re-close the two ends of the ring body 1, restoring the normal monitoring function of all the aforementioned sensors without further adjustment.

[0078] Example 3:

[0079] The difference from Embodiment 1 is that this embodiment provides another driving component. The driving component adopts a linear driver, such as a linear motor or electric cylinder. By directly pushing the intersection of the adjacent second rods 16, the multi-level hinge structure formed by the first rod 15 and the third rod 17 is linked to achieve synchronous and proportionally coordinated deformation of the adjustment area 3, so that the ring body 1 can quickly adapt to the body contours of different patients.

[0080] 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.
