[0003] Traditional fixation methods used in clinical practice (such as suture fixation and dressing adhesion) have significant shortcomings, leading to frequent unplanned extubation incidents of chest tubes. The main causes include: suture dislodgement, loosening of fixation dressings, and excessive external traction. Unplanned extubation not only causes serious clinical consequences for patients (such as affecting treatment, prolonging hospital stays, increasing financial burden, and causing physical and psychological suffering), but also increases the workload of medical staff and raises nursing risks. Therefore, there is an urgent need to improve the safety and reliability of tube fixation through intelligent technologies. Summary of the Invention

[0005] Preferably, the automatic clamping device includes a toothed latch and a miniature servo motor; The toothed buckle has an open ring structure, and its port is connected to the output end of the micro servo motor. The micro servo motor is connected to the control chip and drives the toothed buckle to tighten after receiving a control command to clamp the chest tube.

[0006] Preferably, the clip further includes a support ring, which is a rigid hollow structure and is fixed to the surface of the fixing base; The toothed buckle is installed on the inner side of the support ring, and the micro servo motor is fixed to the top of the support ring.

[0007] Preferably, the inner surface of the toothed buckle is provided with an adhesive material layer.

[0008] Preferably, the small intelligent alarm device also includes a display screen for displaying patient information and the working status of the chest tube.

[0009] Preferably, the communication module is at least one of a WiFi module, a Bluetooth module, or a 4G / 5G communication module, used for communicating with the nursing backend or a mobile terminal.

[0010] On the other hand, an application control method for an intelligent anti-pulling vest is provided, including the following steps: The tension on the chest tube is monitored in real time by the aforementioned tension sensor; If the detected tension exceeds the preset threshold, an alarm signal will be triggered; The automatic clamping device is activated to tighten and clamp the chest tube. The small intelligent alarm device emits a local audible and visual alarm and sends alarm information to the nursing back office or mobile terminal via the communication module.

[0011] Preferably, it further includes: Establish a digital twin model corresponding to the smart anti-extraction vest on a mobile terminal or nursing backend; The digital twin model establishes a mapping relationship between the positions of each clip and the actual positions of the clips on the vest; When an alarm message is received, the alarm status and pipeline information are displayed at the corresponding location on the digital twin model.

[0012] Preferably, it further includes: Configuration information, including patient information, tube type, drainage warning parameters, or bed binding information, is sent to the smart anti-extubation vest via a mobile terminal APP or nursing backend. The configuration information is displayed on the screen of the small intelligent alarm device and is used to adjust the tension threshold or alarm strategy.

[0013] On the other hand, an electronic device is provided, comprising: a processor; and a memory storing computer-readable instructions, which, when executed by the processor, implement the method described above.

[0014] On the other hand, a computer-readable storage medium is provided, wherein at least one instruction is stored therein, the at least one instruction being loaded and executed by a processor to implement the above method.

[0015] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: I. Active anti-tear tube mechanism to improve fixing reliability This invention achieves active protection through a closed-loop control system of "real-time monitoring - automatic clamping - multi-level alarm": Real-time monitoring by tension sensor: The tension sensor built into the clip can detect changes in the force on the chest tube in real time with an accuracy of ±0.3%FS and a response time of <10ms, solving the problem that traditional methods cannot predict the risk of tube removal.

[0016] Automatic clamping device intervenes immediately: When the tension exceeds the preset threshold, the control chip drives the micro servo motor to tighten the toothed buckle, and the mechanical locking prevents the pipe from falling off, which is superior to the passive protection of traditional fixing.

[0017] II. Intelligent alarm and remote collaboration shorten response time This invention improves emergency response efficiency through multi-dimensional alarms and data interoperability: Local + Remote Dual Alarm: The small intelligent alarm device integrates a buzzer and LED indicator, and pushes alarm information to the nursing back office and nurse PDA through a communication module, which reduces the response time by more than 80% compared with traditional manual inspection.

[0018] Precise digital twin positioning: A 1:1 digital twin model is built in the nursing backend, and the position and tension data of the card holder are mapped in real time through WebSocket. Nurses can directly locate abnormal tubes through the 3D model, solving the inefficiency of traditional methods that require checking one by one.

[0019] III. Modular design and dynamic adaptation to optimize clinical usability To address the problems of poor adaptability and low patient comfort associated with traditional fixation methods, this invention innovates in both structure and function: Flexible and adjustable structure: The main body of the vest is made of medical-grade mesh cotton fabric, and the side waist Velcro buckles support ±15cm circumference adjustment to fit patients with a BMI of 18-30; the clips are equipped with 360° rotating joints to adapt to changes in the angle of the tubes during patient movement, solving the problem of limited movement caused by traditional dressings.

[0020] Personalized parameter configuration: Configuration information is sent through a mobile terminal APP, and parameters such as tension threshold and alarm volume can be adjusted according to the patient's condition (such as children, adults, and agitated patients). For example, a 5N alarm threshold can be set for pediatric patients, and a 15N threshold can be set for critically ill adult patients, so as to achieve precise protection with "one policy for one person".

[0021] IV. Data integration and process optimization to reduce nursing burden Unplanned extubation currently increases the workload for medical staff. This invention optimizes the nursing process through digital management and automated recording. Full-process data traceability: Alarm events are automatically recorded with information such as time, location, and peak tension, and synchronized to the hospital's HIS system to generate a "Pipeline Safety Incident Report," reducing manual recording errors and workload.

[0022] Remote monitoring and intervention: The 3D model in the nursing backend supports rotation and zoom. By clicking on the clips, you can view the type of tube (such as chest drainage tube, mediastinal drainage tube) and real-time tension curves. You can make a preliminary judgment without on-site inspection, which improves the efficiency of multi-patient nursing management. Attached Figure Description

Detailed Implementation

[0025] The technical solution of the present invention will now be described with reference to the accompanying drawings.

[0026] In embodiments of the present invention, words such as "exemplarily," "for example," etc., are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in embodiments of the present invention, the meaning expressed by "and / or" can be both, or either one.

[0027] In the embodiments of this invention, the terms "image" and "picture" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning. Similarly, the terms "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning.

[0028] In this embodiment of the invention, sometimes a subscript such as W1 may be mistakenly written as a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0029] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example 1 1. A smart anti-pulling vest Combined with appendix Figure 1 The diagram shows the structure of the vest: (1) Material: The main body of the vest is made of soft, breathable, and elastic medical-grade mesh cotton fabric, which is skin-friendly and comfortable.

[0031] (2) Style: The main body of the vest 1 is a headgear vest with side openings (left and right waist sides). The openings are designed with Velcro buckles 6 (which can be adjusted in size to suit patients of different body types), making it easy to put on and take off and to observe, and it is not easy to come off on its own.

[0032] (3) Color: The main body of the vest uses a gentle light blue and white stripe pattern to reduce the patient's resistance.

[0033] 2. Pipeline fixing clip design on both sides (1) Multiple fixing bases 3 are provided on the outer side of the vest body 1 (mainly the back strap area) (which can be fixed to the body by knitting or pasting). A clip 4 is fixed on the surface of the fixing base 3 (for example, a nylon cable tie with a snap fastener, whose back is fixed to the base by heat fusion). The clip 4 can fix the tube according to the actual position of the chest tube. The clip 4 can be flexibly installed on the corresponding base and fix the tube - chest tube 5. (2) Combined with the appendix Figure 2 and attached Figure 3 As shown, in this case, to achieve immediate and automatic clamping of the chest tube 5 after the tube removal sensor is activated, the clamp 4 is designed as an automatic clamping device (such as a toothed buckle) to ensure a firm fit and prevent loosening. (See attached diagram.) Figure 2 The illustrated clip 4 application example structure uses a toothed buckle 9 (a flexible material with a toothed inner surface; it is not a closed loop when bent, but its port is connected to the output of a micro servo motor 7, similar to the structure of a "stainless steel cable tie," but here it is not manually tightened; instead, the servo motor 7 tightens the port to achieve automatic clamping). The toothed buckle 9 is an open ring with its port connected to the output of a micro servo motor 7. To maintain its stability, it can be mounted on a support ring 8 (hard plastic). See attached... Figure 2As shown, the support ring 8 features a hollow design (to reduce weight). Its bottom can be fixed to the surface of the base 3 via heat fusion or other methods. A toothed clip 9 is fitted onto the inner side of the support ring 8. The inner side of the support ring 8 can have a pre-drilled groove (similar to the fitting structure of a bearing ball bearing outer ring) to accommodate the toothed clip 9 and prevent it from falling off. Alternatively, the back of the toothed clip 9 can be integrally formed with an open groove, allowing the support ring 8 to fit within the groove. A micro servo motor 7 is fixedly mounted (via heat fusion or screws) on the top surface of the support ring 8. The output end can be positioned parallel to the tube and wound around the end of the toothed clip 9 using a gear set design, or the end of the toothed clip 9 can be directly wound and fixed to the output end using a flexible material. The micro servo motor 7 is connected to the control chip MCU in the small intelligent alarm device 2 via concealed wiring and is started by the MCU controller. When the MCU in the small intelligent alarm device 2 receives the tension sensing signal from the tension sensor, it immediately sends a command to the micro servo motor 7 to control its rotation and tighten the toothed buckle 9 to clamp the chest tube 5.

[0034] (3) The inside of the toothed buckle 9 can also be fitted with an adhesive material (such as double-sided tape) to enhance the pipe fixing effect.

[0035] Intelligent alarm solution for intelligent anti-pulling vest (core - application control method) (1) Each clamp 4 has a miniature tension sensor and an automatic clamping device. When the pipe is subjected to abnormal external force (the force can be set to a threshold, such as greater than the force generated by normal activity), the tension sensor can be triggered to start the automatic clamping system, and the clamp will completely clamp the pipe.

[0036] (2) The vest has a small intelligent alarm device 2. The outer shell is square and fixed to the main body. The outer shell integrates a display screen (displaying basic patient information, chest tube working information, medical orders, etc.). The inner shell integrates an MCU, a buzzer, a power supply, a tension sensor, and a communication module (wifi / Bluetooth or 4 / 5G communication module, etc., which can communicate with the nursing backend and report tension alarm information). The tension sensor is connected to the clips on both sides. When the miniature tension sensor detects abnormal external force (patient tube removal), it can trigger the intelligent alarm device, which will emit a clear buzzer sound and prompt, reminding the patient, family members, and medical staff to pay attention to tube safety.

[0037] (3) Visualized Tube Alarm Reminder: The small intelligent alarm device has communication function. Each fixed clamp base has a chip setting. There is a terminal APP on the mobile phone / PDA. The mobile terminal can input the corresponding configuration information (such as the name of the patient's chest tube 5, drainage warning information (drainage duration or drainage fluid threshold, etc.), the patient's bound bed information, etc.) and send it to the small intelligent alarm device 2 through the nursing backend. The communication module of the small intelligent alarm device 2 receives it and forwards it to the MCU. The MCU sends the configuration information and displays it on the display screen. When the intelligent alarm device is triggered, the alarm information is sent to the mobile phone or PDA of medical staff in real time. The APP displays the tube distribution image (if the patient has multiple chest tubes 5, each chest tube 5 can be simulated and displayed on the digital twin vest model of the APP. Each point of the model corresponds to the sensor at the corresponding position. The tube at the position of the sensor information received is displayed on the vest model. Here, the APP can build a twin model of the corresponding intelligent anti-pulling vest based on digital twin technology and establish the mapping relationship between each model point and the corresponding clamp position, as well as the relationship between each The binding relationship between position tension sensors allows for the subsequent removal of the chest tube 5 at position A (where tension sensor A is located). If this tube is pulled out, an alarm will be triggered, and the corresponding information, along with the sensor number, will be reported to the backend. The backend will then know that the tube has become loose at position A and can send a control command to the automatic clamping device at that position, causing its servo motor to start, rotate, and retract the toothed latch 9. Therefore, the chip indicator signal can clearly indicate which tube on the patient is alarmed and the type of alarm, enabling precise location and timely intervention. It also allows nurses and family members to visually see the tube removal position.

[0038] If there are pipes of different properties, the corresponding pipe type can be written in the corresponding position of the model. This makes it easier to understand the working status of each pipe when displayed in the app. An example image of the app display interface is attached (this is just an example; page rendering needs optimization and adjustments). Figure 4 As shown.

[0039] Application examples are as follows: Measuring range: 0-200N (accuracy ±0.3%FS).

[0040] Power supply voltage: 5V DC.

[0041] Output signal: 2mV / V.

[0042] Response time: <10ms.

[0043] Protection rating: IP64.

[0044] The automatic clamping device uses a Cangxingda 10**M5 micro servo motor (10mm in diameter, 43mm in length) and a toothed snap-lock structure. Rated voltage: 12V DC.

[0045] Rated speed: 3000 rpm.

[0046] Output torque: 0.5 Nm.

[0047] Control accuracy: ±1°.

[0048] Operating temperature: -20~65℃.

[0049] Usage procedure: The nurse selects the corresponding fixing base according to the patient's chest tube position, puts the tube into the toothed buckle (with 3M medical pressure-sensitive adhesive on the inside), and fixes it with the support ring (ABS material, hollow design). During system initialization, the nurse sets the tube type (such as chest drainage tube, mediastinal drainage tube) and sets the tension threshold (15N for normal, 8N for agitated patients) through the PDA terminal.

[0050] 2. Application control logic The system uses the STM32L476RG control chip (MCU) as its core and integrates the following modules: Signal acquisition layer: 8-channel tension sensors convert signals through the HX711AD module, with a sampling frequency of 100Hz, and use an IIR low-pass filter (cutoff frequency 5Hz) to remove motion interference.

[0051] Decision-making level: Implementing a three-level judgment logic: Level 1 Warning (1-5N): Local LED indicator flashes (green). Level 2 warning (5-15N): The buzzer emits an intermittent warning tone (1kHz, 0.5s interval). Level 3 alarm (>15N): The servo motor is activated to clamp (clamping force 30N, lasting 2 seconds), the buzzer sounds continuously (2kHz), and alarm information is sent simultaneously. Execution layer: The servo motor drive adopts PID control to ensure that the clamping force error is less than 5%, and the current is reduced to 30% of the rated value after clamping (energy saving mode).

[0052] The power management system employs a dual-battery design: the main battery (3.7V / 2000mAh lithium polymer battery) supports 12 hours of continuous operation, while the backup battery (CR2032) ensures that the alarm function can still operate for 4 hours in the event of main battery failure. The charging port features a MagSafe magnetic design to prevent accidental pulling by patients.

[0053] 3. Digital Twin Model Construction and Data Mapping The backend system uses Three.js to build a 1:1 scale digital twin vest model. The modeling process includes: Geometric modeling: Use Blender to create a 3D mesh for the vest (approximately 5000 faces) and accurately locate the coordinates of the 8 clip positions (error <0.5mm).

[0054] Material mapping: The texture of light blue striped fabric is reproduced using PBR material, with a metallicity of 0.2 and a roughness of 0.6.

[0055] Skeletal rigging: 12 control points were established to simulate the patient's breathing movements and achieve dynamic deformation of the model.

[0056] The data mapping uses WebSocket real-time communication (30fps) to achieve the following functions: Sensor data visualization: The tensile force value is displayed using color coding (green 0-5N, yellow 5-15N, red >15N).

[0057] Pipeline status simulation: Render the corresponding pipe model on the model according to the actual pipe diameter (8-12Fr).

[0058] Historical data review: Supports viewing the tensile force change curve over the past 24 hours (sampling interval 1 second).

[0059] The developed nursing backend interface includes the information in the following table: Module Function Description Real-time monitoring panel Displays the vest status of all patients; patients with abnormalities are highlighted in red. 3D model view It can be rotated and scaled; click on the card slot to view detailed parameters. Alarm Log Record alarm time, location, peak tension, and processing result. Parameter configuration Remotely adjust the tension threshold of each pipe, alarm volume, etc. 4. Alarm Nursing Procedure When the system triggers a Level 3 alarm, the following nursing procedure will be executed: Alarm Trigger: The local device emits an audible and visual alarm, and simultaneously sends the alarm information to the nursing back office and the responsible nurse's PDA via the 4G module (Quectel EC20) (delay <3 seconds).

[0060] Information presentation: The PDA displays the patient's bed number, tube location (e.g., "right 3rd intercostal chest tube"), real-time tension curve, and suggested treatment plan.

[0061] On-site handling: After the nurse arrives, she will deactivate the alarm using an NFC card reader, check the position of the tube, and after confirming that there is no dislocation, send a "processed" command via PDA, and the system will resume monitoring status.

[0062] Data logging: All alarm events are automatically written into the hospital's HIS system, generating a "Pipeline Safety Incident Report".

[0063] Clinical trials have shown that this system can reduce the rate of unplanned extubation in scenarios such as the ICU, shorten nurse response time to an average of 1-3 minutes, and keep the false alarm rate below 3%.

[0064] Example 2 A pediatric patient-specific anti-extubation vest system based on the technical principles of Embodiment 1. 1. Vest's specific structure and usage. Designed for children aged 3-12, this vest uses Jinlei 71 series four-way stretch fabric (N / SP 90 / 10, 120GSM), which has passed the GB / T 21196.2-2007 abrasion resistance test of 40,000 cycles and has a 150% tensile recovery rate. The main body of the vest features cartoon animal designs (such as bears and rabbits), with a sky blue main color (Pantone 15-4120) and fluorescent yellow stripes (Pantone 13-0840) to increase visual appeal.

[0065] The product comes in three sizes: S (3-6 years old, chest circumference 50-65cm), M (7-9 years old, chest circumference 65-80cm), and L (10-12 years old, chest circumference 80-95cm). The Velcro closures feature rounded corners (5mm radius) and a width reduced to 1.5cm to avoid pressing on children's delicate skin.

[0066] The sensing system employs a miniaturized design: Tension sensor: FL25-50N (range 0-50N, size 25×15×8mm, weight 8g).

[0067] Servo motor: Cangxingda 08**M5 (diameter 8mm, length 38mm, weight 12g, output torque 0.1Nm).

[0068] Alarm device: Integrated into the animal ear design, using a 12mm diameter passive buzzer (65dB volume, to avoid startling children).

[0069] Optimized usage: Donning and doffing design: It adopts a front-opening zipper and Velcro double fixation, which reduces the donning and doffing time by 60% compared with traditional restraint belts.

[0070] Pipe securing: The clip is equipped with a rotatable joint (360° rotation, ±45° tilt) to accommodate changes in pipe angle during children's activities.

[0071] Soothing function: The vest has a built-in detachable plush toy pendant to reduce the child's anxiety through tactile stimulation.

[0072] 2. Application control logic The pediatric system employs a graded response control strategy, with core parameters shown in the table below: parameter Baby mode (3-6 years old) School-aged children (7-12 years old) Tensile threshold 5N (Alarm) 8N (Alarm) Clamping force 15N (lasts for 1 second) 20N (lasts 1.5 seconds) Alarm volume 55dB (soft music) 65dB (beep tone) Battery life 16 hours 14 hours Specially designed anti-accidental touch logic: Dynamic threshold adjustment: The threshold is automatically adjusted according to the child's activity status (determined by a triaxial accelerometer), decreasing to 3N during sleep and increasing to 10N during activity.

[0073] Dual confirmation mechanism: The alarm is triggered 0.5 seconds after the pulling force exceeds the threshold to avoid false alarms caused by instantaneous pulling.

[0074] Parental authorization function: The alarm can be temporarily deactivated (up to 10 minutes) via a dedicated APP, making it convenient for feeding, diaper changing and other care operations.

[0075] 3. Digital Twin Model Construction and Data Mapping The pediatric digital twin system is developed using the Unity3D engine and has the following features: Cartoonized models: combine vest models with animal images (such as digital twin models of bear-shaped vests), and use colored flexible tubes to represent pipes (red - artery tube, blue - vein tube, yellow - drainage tube).

[0076] Interactive features: Parents can interact with the model by touching the screen and click on the clips to view tube information (such as "This is a drainage tube to help drain pleural effusion from the baby").

[0077] Education module: Includes simple medical knowledge animations (such as "Why does your baby need this tube") to help parents understand the treatment process.

[0078] Data visualization uses child-friendly presentation methods: The tension value is expressed as the degree of balloon inflation (the greater the tension, the larger the balloon).

[0079] Alarm status is indicated by changes in animal facial expressions (normal - smiling, warning - surprised, alarm - crying).

[0080] Historical data is presented in the form of growth curves, which helps doctors assess the child's compliance.

[0081] 4. Alarm Nursing Procedure Pediatric emergency response emphasizes gentle intervention: Alarm classification: Level 1 (3-5N): Vest animal ear LED lights flash (blue).

[0082] Level 2 (5-8N): Play soothing music (a segment from "Twinkle Twinkle Little Star").

[0083] Level 3 (>8N): Music + Vibration (50Hz, 0.5s interval) + Remote Alarm.

[0084] Parental collaboration: The alarm information is sent to both the nurses' station and the parents' mobile phones. Parents can check the real-time situation through the APP and provide initial reassurance before the nurse arrives.

[0085] Procedure: The nurse uses a special key card to deactivate the alarm, and records the child's reaction (calm / crying / struggling) via PDA while checking the tubing. The system automatically associates the pain score (FLACC scale).

[0086] Psychological intervention: After each alarm is handled, the system prompts the nurse to take comforting measures (such as telling stories or using toys to distract attention) and records the intervention effect.

[0087] During a three-month trial at a children's hospital, the system reduced the rate of unplanned tube removal in pediatric patients from 28% to 9%, and improved the patients' compliance score (0-10 points) with treatment to 7.6 points.

[0088] Example 3: Home Care Scenario Anti-removal System 1.

[0097] Gateway: Uploads data to the cloud via home WiFi, supporting remote configuration of parameters and firmware upgrades.

[0098] In the cloud: The AWS IoT platform provides data storage, analysis, and alerting services.

[0099] Core control strategy: Adaptive threshold: The alarm threshold is dynamically adjusted based on the patient's daily activity patterns (through machine learning algorithms), such as automatically reducing sensitivity when the patient is asleep.

[0100] Tiered alarm: Light tension (<10N): Local LED indicator only.

[0101] Moderate tension (10-20N): Local audible and visual alarm.

[0102] Severe traction (>20N): Local alarm + family member's mobile phone push + community nurse notification.

[0103] Energy-saving mode: The sampling frequency is 1Hz under normal conditions, and automatically increases to 100Hz when a change in tension is detected, with the average power consumption controlled at 50mW.

[0104] 3. Digital Twin Model Construction and Data Mapping The home version of the digital twin system is developed based on WebGL technology and can be accessed through a regular browser. Its main functions include: Simplified model: A low-poly model (approximately 1000 faces) is used to ensure smooth operation on mobile devices.

[0105] Real-time status display: Pipe tension: indicated by line color and thickness (green for normal, red for abnormal).

[0106] Device status: battery level, signal strength, sensor operating status.
