DETAILED DESCRIPTION

[0016] The embodiments of the present application provide a foldable hydrogen peroxide sealed disinfection cabin based on the Internet of Things and its intelligent control system and method, thereby solving the technical problems of insufficient portability, poor disinfection accuracy and lack of intelligent management of traditional medical disinfection equipment in the disinfection scenario of non-movable equipment. The disinfection cabin is portable and quickly deployed, with precise disinfection and full-process data traceability, thereby improving the disinfection efficiency and safety of non-movable equipment in semi-open spaces.

[0017] Example 1, as Figure 1 As shown, the embodiment of the present application provides a foldable hydrogen peroxide sealed disinfection cabin based on the Internet of Things, and the disinfection cabin includes:

[0018] A foldable cabin module 1 includes a memory alloy support frame, an electric hydraulic folding mechanism and a folding state detection sensor.

[0019] Specifically, the structure utilizes a shape memory alloy support frame. Shape memory alloys possess shape memory properties, allowing them to automatically return to their preset configuration under temperature fluctuations. This ensures structural stability after the capsule is deployed, eliminating the need for manual calibration and providing a reliable physical space for disinfection. Secondly, an electro-hydraulic folding mechanism is installed, hydraulically actuated to deploy and fold the capsule. This optimized design allows the capsule to achieve a folding ratio of ≥1:8, reducing its volume in the stowed state to less than one-eighth of its deployed state. This significantly reduces the device's footprint when idle and enhances portability. For example, traditional fixed devices typically occupy >2 square meters, while this solution reduces its volume by over 75% after folding, making it easier to transfer between hospital departments or transport by vehicle. Furthermore, the placement of a folding state detection sensor is crucial. This sensor monitors the capsule's degree of deployment in real time. Upon receiving a remote control command to activate the electro-hydraulic folding mechanism to deploy the capsule, the sensor continuously provides feedback until the capsule reaches the preset deployed configuration. This ensures the capsule's structural integrity and sealing before disinfection, preventing incomplete deployment from compromising disinfection effectiveness.

[0020] The hydrogen peroxide atomization module 2 is disposed inside the foldable cabin module 1 .

[0021] Specifically, the hydrogen peroxide atomization module 2 includes an atomization nozzle and a concentration feedback control module, and achieves precise disinfection through the following steps:

[0022] First, the atomizing nozzle serves as the core execution unit, responsible for converting the hydrogen peroxide solution into droplets. By optimizing the nozzle design, droplets of appropriate particle size (such as 5-10μm dry mist) can be generated to ensure uniform diffusion in the cabin and effective penetration of the disinfection object. For example, for the hospital mattress disinfection scenario, 8% concentration of hydrogen peroxide dry mist (particle size 5μm) can fully penetrate a 15cm thick mattress within 60 minutes, with a killing rate of >99.9% (for pathogens such as MRSA and C.diff). The continuous working time and output of the atomizing nozzle are automatically adjusted according to the disinfection task data (such as the volume and material of the object to be disinfected) to achieve differentiated and precise spraying.

[0023] Secondly, the concentration feedback control module uses an integrated gas sensor to monitor the hydrogen peroxide concentration in the chamber in real time and transmits this data to the IoT management module. When the concentration falls below a preset threshold, the system automatically increases the atomization volume. If the concentration exceeds a safe range, the spraying is suspended and ventilation is initiated. This closed-loop control mechanism keeps concentration errors within ±5%, eliminating the dosage inaccuracies that arise from empirical judgment in traditional manual operations. For example, during the disinfection process, if changes in ambient temperature and humidity cause changes in the droplet evaporation rate, the concentration feedback control module can respond within 200ms and adjust the atomization parameters to ensure stable disinfection results.

[0024] A dedicated adapter interface module 3, wherein the dedicated adapter interface module 3 is used to connect to medical equipment.

[0025] Specifically, first, the dedicated adapter interface module 3 includes a pressure-sensing sealing device, whose core function is to form a local enclosed space between the disinfection cabin and the medical equipment. When the foldable cabin module 1 is unfolded to the preset shape, the operator aligns the interface module with the equipment to be disinfected (such as the head and foot brackets of the bed), and pushes the interface close to the surface of the equipment manually or electrically. At this time, the pressure sensor in the pressure-sensing sealing device monitors the contact pressure in real time. When the pressure reaches the preset threshold (such as 5-8kPa), it triggers the expansion or deformation of the sealing material, filling the gap between the interface and the equipment to form an airtight connection with a leakage rate of <0.05L / (m·s). For example, for the metal frame of a standard hospital bed, the device can complete the seal within 30 seconds, ensuring that the disinfection droplets cover the surface and bottom space of the equipment without dead angles.

[0026] Secondly, the geometric structure of the interface module is optimized based on the shape of common medical equipment and supports three-dimensional curved surface fitting. For example, for the curved edge of the operating table, the inner side of the interface is made of flexible silicone material, which can bend adaptively and fit tightly to avoid sealing failure caused by the irregular shape of the equipment. At the same time, the interface module reserves multiple atomizing nozzle connection ports, which are connected to the hydrogen peroxide atomizing module 2 in the cabin, so that the droplets can be sprayed directly through the interface to the gaps, bottom and other areas of the equipment that are traditionally difficult to reach, achieving a three-dimensional surround atomization effect. After adopting this interface module, the sterilization coverage rate has increased from 60-80% of traditional methods to 99.9%, significantly eliminating blind spots in disinfection.

[0027] The Internet of Things management module 4 is used to remotely control the foldable cabin module 1 , the hydrogen peroxide atomization module 2 and the dedicated adapter interface module 3 .

[0028] Specifically, first, the IoT management module 4 integrates a 5G communication module as a core component for remote interaction. When medical staff send remote control commands (such as unfolding the cabin, starting disinfection) through a mobile phone or PC, the 5G module receives the command with a response delay of <200ms and transmits the signal to the execution units such as the electric hydraulic folding mechanism and the hydrogen peroxide atomization module 2. For example, after the cabin unfolding command is remotely triggered, the electric hydraulic folding mechanism completes the unfolding action within 90 seconds, and the folding state detection sensor synchronously transmits the unfolding position signal back to the terminal through the 5G module, realizing real-time visualization of the operation process.

[0029] Secondly, the disinfection database serves as the data management hub, storing historical disinfection task data and preset plans. After the system obtains the target disinfection task data (including information on the object to be disinfected, ambient temperature and humidity, disinfectant reserves, etc.), the disinfection database matches the optimal plan through the AI algorithm. For example, for metal operating tables, the database automatically calls a plan with an 8% hydrogen peroxide concentration and a 45-minute action time; for fabric mattresses, it calls a plan with a 6% concentration and a 60-minute action time. At the same time, the database uses the AES-256 encryption algorithm to store data and supports blockchain evidence storage to ensure that disinfection records cannot be tampered with and meet the data traceability requirements of medical infection control (such as JCI certification standards).

[0030] In one possible implementation, the foldable cabin module 1 further includes:

[0031] The foldable cabin module 1 is made of multiple layers of nanofiber composite material, and the thickness of the multiple layers of nanofiber composite material is 0.5 mm to 1.2 mm.

[0032] Specifically, a multi-layer nanofiber composite material is prepared through an electrospinning process, spinning polymer materials such as polyvinylidene fluoride (PVDF) and polypropylene (PP) into nanofibers with a diameter of 50-200nm. These fibers are then stacked in layers to form a composite structure. The material is controlled to be 0.5-1.2mm thick, significantly thinner than traditional metal sheets (thickness > 3mm), reducing the overall weight of the cabin and improving handling efficiency.

[0033] Secondly, the high specific surface area of nanofibers imparts excellent mechanical properties to the material. The interlayer fibers physically entangle to form a mesh structure with a tensile strength of 15-20 MPa, sufficient to withstand the folding stress of the memory alloy frame. In folding tests, a 1.0 mm thick composite material experienced a breakage rate of less than 3% after 5,000 folding cycles, significantly outperforming traditional flexible plastics (breakage rate >15%).

[0034] By utilizing multi-layer nanofiber composite materials, the foldable cabin module 1 achieves breakthroughs in thickness, weight, sealing, and durability, meeting the requirements for rapid deployment in emergency disinfection scenarios. Furthermore, the material's high sealing properties ensure a stable hydrogen peroxide concentration during disinfection. Combined with the structural support of the memory alloy frame, this significantly improves portability and space efficiency while maintaining the cabin's sealing and durability.

[0035] In one possible implementation, the foldable cabin module 1 further includes:

[0036] The folding ratio of the electro-hydraulic folding mechanism is greater than or equal to 1:8.

[0037] Specifically, first of all, the electric hydraulic folding mechanism adopts a four-link linkage structure, and the joint hinge is driven by a hydraulic cylinder to realize the expansion and folding of the cabin. During the design stage, the finite element analysis (FEA) was used to optimize the length ratio of the connecting rod and the position of the hinge point, so that the cabin can achieve symmetrical contraction during the folding process and avoid structural deformation caused by stress concentration. When the working pressure of the hydraulic system is set to 8-12MPa, it can drive the memory alloy frame to complete the entire process from expansion to folding, and the folding ratio can be as high as 1:8 (for example, the size of the cabin in the expanded state is 2400mm×1200mm×2000mm, and it is compressed to 300mm×1200mm×2000mm after folding, and the volume is reduced by 7 / 8).

[0038] Secondly, the folding mechanism integrates a speed feedback sensor to monitor the folding rate in real time and dynamically adjust the hydraulic flow. When the cabin nears full fold, the system automatically reduces the hydraulic flow rate to avoid material damage caused by rigid collisions. The entire folding process takes less than 90 seconds (compared to traditional mechanical folding, which takes over 300 seconds).

[0039] Through the innovative design of the electric hydraulic folding mechanism, the foldable cabin module 1 achieves the dual goals of high folding ratio and rapid expansion and contraction, achieving the effect of greatly improving portability and space utilization efficiency while ensuring the structural strength of the cabin.

[0040] In one possible implementation, the hydrogen peroxide atomization module 2 further includes:

[0041] The hydrogen peroxide atomization module 2 includes an atomization nozzle and a concentration feedback control module.

[0042] Specifically, first, the atomizing nozzle uses ultrasonic vibration atomization technology to convert the hydrogen peroxide solution into dry mist particles with a particle size of 5-10μm. This particle size range not only ensures the stability of the aerodynamic characteristics of the droplets in the cabin (sedimentation velocity <0.05m / s), but also can fully diffuse to the surface of complex structures (such as instrument gaps, deep in the mattress fibers) through Brownian motion. Experimental data show that 8% concentration of hydrogen peroxide dry mist can fully penetrate a 15cm thick mattress within 60 minutes, and the killing rate for pathogens such as MRSA and C.diff is >99.9%. The flow rate of the nozzle can be automatically adjusted according to the volume of the disinfection object. For example, for a standard hospital bed (volume of about 2.5m 3 ), the nozzle sprays continuously at a flow rate of 10ml / min for 20 minutes to ensure that the dosage reaches 10-15ml / m 3 standard requirements.

[0043] Secondly, the concentration feedback control module uses a built-in electrochemical sensor to monitor the hydrogen peroxide concentration in the chamber in real time, with an accuracy of ±0.5ppm. The sensor collects data every 5 seconds and transmits it to the IoT management module 4. The system then uses a PID control algorithm to calculate the start and stop times and flow adjustment range of the atomizer nozzle. When the concentration detects that it is below a preset value (such as a ±5% threshold of a standard concentration of 6%), the module automatically increases the spray volume. If the concentration exceeds the safety limit (such as 10ppm), the spray is suspended and the ventilation fan in the chamber is activated. This closed-loop control mechanism keeps concentration fluctuations within ±5% during the disinfection process, reducing errors by over 80% compared to traditional manual operation. For example, in an environment with large temperature and humidity fluctuations (temperature 25±3°C, humidity 60±10%RH), the module can respond and adjust parameters within 200ms to ensure a stable kill rate of 99.9%.

[0044] Through the precise atomization of the atomizing nozzle and the dynamic adjustment of the concentration feedback control module, the hydrogen peroxide atomization module 2 realizes the automated process of spraying-monitoring-adjustment, achieving the effect of improving disinfection efficiency while ensuring precise controllable dosage and reducing residual risks.

[0045] In one possible implementation, the dedicated adaptation interface module 3 further includes:

[0046] The dedicated adapter interface module 3 includes a pressure-sensing sealing device.

[0047] Specifically, the pressure-sensing seal utilizes a flexible silicone material combined with a pressure sensor. When the interface module approaches the surface of the medical device, the operator pushes the module to bring the silicone seal into contact with the device. The pressure sensor then monitors the contact pressure in real time. When the pressure reaches a preset threshold of 5-8 kPa, the sensor triggers a pneumatic expansion mechanism within the seal, causing the silicone seal to expand and fill the gap, creating an airtight connection.

[0048] Secondly, the sealing device is connected to the hydrogen peroxide atomization module 2 inside the cabin, automatically activating the surround spray mode after sealing. For example, to address the complex structure at the bottom of a hospital bed, the interface module's reserved lateral nozzles can spray 5μm dry mist directly into the space below the device. This, combined with the vertical spray from the nozzles on the top of the cabin, creates a three-dimensional atomization field. Testing has shown that the use of this device has increased the sterilization coverage rate to 99.9% in traditionally blind spots such as the bed bottom and bracket gaps, and the kill rate for pathogens such as MRSA and C. diff meets the standards for terminal disinfection.

[0049] In addition, the pressure-sensing sealing device is linked to the IoT management module 4. After sealing is completed, the folding state detection sensor sends a feedback signal to the system, triggering the automatic start of the disinfection process. If the pressure sensor detects a sudden drop in sealing pressure (e.g., a drop of >2kPa) during the disinfection process, the system immediately pauses the spray and sends an alarm to avoid incomplete disinfection or gas leakage due to seal failure.

[0050] Through the dynamic pressure control and three-dimensional atomization design of the pressure-sensing sealing device, the dedicated adapter interface module 3 solves the sealing problem between traditional disinfection equipment and fixed medical devices. This device triggers automatic sealing based on a pressure threshold. Combined with the directional spray of the atomizing nozzle, this device reduces the number of blind spots in the disinfection of immovable equipment in semi-open spaces while ensuring that hydrogen peroxide gas is leak-free during the disinfection process. Ultimately, the synergy between pressure-sensing sealing technology and the atomization system achieves the goal of achieving precise disinfection without blind spots and improving the reliability of disinfection effects in complex medical scenarios.

[0051] In one possible implementation, the Internet of Things management module 4 further includes:

[0052] The Internet of Things management module 4 includes a 5G communication module and a disinfection database. The 5G communication module is used for remote interaction, and the disinfection database is used to encrypt and store disinfection data.

[0053] Specifically, first, the 5G communication module serves as the data transmission hub, supporting medical staff to remotely send instructions to the disinfection cabin through terminal devices (mobile phones / PCs). When the operator clicks the command to unfold the cabin on the terminal, the 5G module transmits the signal to the electric hydraulic folding mechanism with a delay of less than 200ms, driving the cabin to complete the unfolding action within 90 seconds. At the same time, real-time data such as the folding state detection sensor and the concentration feedback control module are transmitted back to the terminal via the 5G network, forming a dynamic monitoring screen, such as the temperature and humidity in the cabin, the hydrogen peroxide concentration curve, etc., so that the operator can grasp the status of the entire process without entering the disinfection area.

[0054] Secondly, the disinfection database uses the AES-256 encryption algorithm to store disinfection task data, including information about the object to be disinfected, environmental parameters, disinfection plans, and execution records. After each disinfection task is completed, the system automatically encrypts the data and uploads it to the database, with storage accuracy down to the second level (such as recording the start time of spraying, the moment of peak concentration, etc.). The database supports blockchain evidence storage to ensure that the data cannot be tampered with and meets the traceability requirements of international medical certifications such as JCI. For example, when it is necessary to trace the disinfection records of a certain bed, the full process parameters of the corresponding task can be quickly retrieved through the database.

[0055] In addition, the 5G communication module and the disinfection database work together to achieve intelligent solution matching. The Internet of Things management module 4 obtains the target disinfection task data (such as the material of the equipment to be disinfected is metal, the volume is 3m 3 ), the database matches the optimal solution (such as 8% hydrogen peroxide concentration and 45 minutes of action time) from the historical data and sends the parameters to the hydrogen peroxide atomization module 2 for execution.

[0056] Through the high-speed data transmission of the 5G communication module and the intelligent management of the disinfection database, the IoT Management Module 4 integrates remote control, real-time monitoring, and data traceability. 5G technology ensures low-latency interaction between commands and data, an encrypted database safeguards medical data security, and AI algorithms optimize the disinfection process. This approach not only enhances the intelligence of the disinfection process but also meets the multiple requirements of medical infection control for remote operation, data security, and process standardization.

[0057] In summary, the foldable, IoT-based, sealed hydrogen peroxide disinfection chamber provided in the embodiments of the present application has the following technical effects:

[0058] The embodiment of the present application comprehensively improves the disinfection efficiency and safety of immovable medical equipment through the innovative design of the foldable cabin module 1, the precise control of the hydrogen peroxide atomization module 2, the sealed connection of the dedicated adapter interface module 3 and the intelligent linkage of the Internet of Things management module 4. The high folding ratio (≥1:8) and rapid unfolding (<90 seconds) of the cabin are achieved through the memory alloy support frame and the electric hydraulic folding mechanism, and the sealing and portability are guaranteed by combining a multi-layer nanofiber composite material (thickness 0.5-1.2mm); the hydrogen peroxide concentration is dynamically adjusted by the atomizing nozzle and the concentration feedback control module, and a local enclosed space is formed with the pressure sensing sealing device, so that the sterilization coverage rate reaches 99.9%; remote control and data traceability are achieved through the 5G communication module (response delay <200ms) and the disinfection database (encrypted storage, blockchain evidence). The entire system can accurately capture the disinfection needs of immovable equipment in medical scenarios, dynamically adjust the disinfection parameters, and reduce the residual risk (<1ppm) while improving the disinfection effect, providing an intelligent and standardized solution for medical infection control and ensuring the safety and stability of the medical environment.

[0059] Example 2, as Figure 2 As shown, based on the same inventive concept as the above embodiment, the embodiment of the present application provides an Internet of Things-based foldable hydrogen peroxide sealed disinfection cabin intelligent control system, the system comprising:

[0060] The remote control instruction receiving unit 5 is used to receive the remote control instruction through the Internet of Things management module 4, and drive the electric hydraulic folding mechanism according to the remote control instruction to unfold the foldable cabin module 1 to a preset unfolding shape; the disinfection task data acquisition unit 6 is used to obtain the target disinfection task data according to the Internet of Things management module 4, and the target disinfection task data includes the information of the object to be disinfected, the ambient temperature and humidity information and the disinfectant reserve information; the disinfection task data input unit 7 is used to input the target disinfection task data into the disinfection database, obtain a matching disinfection plan, and perform disinfection in combination with the hydrogen peroxide atomization module 2; the disinfection record uploading unit 8 is used to control the foldable cabin module 1 to automatically fold to the storage state according to the electric hydraulic folding mechanism when the disinfection is completed, and upload the disinfection record to the disinfection database.

[0061] Specifically, the system first receives remote control commands (such as cabin deployment) through the 5G communication module of the IoT management module 4, with a response delay of less than 200ms. This command triggers the activation of the electro-hydraulic folding mechanism. Driven by 8-12MPa hydraulic pressure, the memory alloy support frame unfolds along a preset trajectory. The folding state detection sensor feeds back joint angle data at 100ms intervals until the cabin reaches the preset configuration (error less than 1.5°). The entire process takes less than 90 seconds.

[0062] After the cabin is deployed, the system collects targeted disinfection task data in real time through the IoT management module 4. Information about the object to be disinfected (such as bed material and volume) is acquired through infrared scanning via the adapter interface module. Ambient temperature and humidity are monitored by sensors within the cabin (with an accuracy of ±0.5°C / ±3%RH). The disinfectant level is read by the atomization module's liquid level sensor (with a resolution of 1ml). After preprocessing, the data is stored in a real-time database with an accuracy exceeding 99%.

[0063] The disinfection database matches the best solution from historical cases based on the input task data. For example, for a metal operating table (volume 4m 3 , 25°C / 40% RH), matching a protocol of 8% H2O2 concentration, 20ml / min flow rate, and 45 minutes of exposure time, with a parameter error of less than ±5%. This protocol drives the execution of the hydrogen peroxide atomization module 2, and the concentration feedback control module adjusts the spray volume in real time with an accuracy of ±0.5ppm, ensuring a kill rate greater than 99.9%.

[0064] Once disinfection is complete, the system automatically triggers the electric hydraulic folding mechanism to retract in reverse, completing the folding of the cabin within 90 seconds (folding ratio ≥ 1:8). Simultaneously, the IoT management module 4 uploads the entire disinfection process data (including object information, environmental parameters, dosage, residual values, etc.) to the disinfection database via AES-256 encryption, supporting blockchain-based evidence storage and meeting medical infection control traceability requirements (such as JCI standards).

[0065] Through the command transmission and data integration of the Internet of Things management module 4, the precise driving of the electric hydraulic mechanism, the intelligent matching of the disinfection database and the dynamic control of the atomization module, it is achieved that while improving the disinfection efficiency, it also realizes operation standardization, data traceability and unmanned management.

[0067] Step A100: receiving a remote control instruction through the Internet of Things management module 4, and driving the electric hydraulic folding mechanism according to the remote control instruction to unfold the foldable cabin module 1 to a preset unfolding configuration.

[0068] Step A200: Obtain target disinfection task data according to the Internet of Things management module 4, wherein the target disinfection task data includes information of the object to be disinfected, environmental temperature and humidity information, and disinfectant reserve information.

[0069] Step A300: Input the target disinfection task data into the disinfection database, obtain a matching disinfection plan, and perform disinfection in conjunction with the hydrogen peroxide atomization module 2.

[0070] Step A400: When the disinfection is completed, the foldable cabin module 1 is automatically folded to the storage state according to the control of the electric hydraulic folding mechanism, and the disinfection record is uploaded to the disinfection database.
