[0021] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] The present invention provides a nasoenteric tube placement qualification certification and review system, which consists of five core modules: an adaptive virtual reality training module, a multimodal artificial intelligence evaluation module, a quantum encryption biometric module, a distributed ledger recording module, and an artificial intelligence-assisted decision-making and risk warning module. These modules are interconnected through a secure communication network to form a complete closed-loop system, thereby realizing the full-process intelligent certification and review of nasoenteric tube placement qualifications. In this system, the adaptive virtual reality training module provides an immersive training environment for medical staff, the multimodal artificial intelligence evaluation module evaluates the training and actual operation process in real time, the quantum encryption biometric module ensures the security of system access and the reliability of identity authentication, the distributed ledger recording module securely stores all training, evaluation and certification data, and the artificial intelligence-assisted decision-making and risk warning module provides decision support and risk warnings based on the collected data. The collaborative work of these five modules constitutes a complete, secure, and intelligent nasoenteric tube placement qualification certification and review system. The overall architecture of the system is as follows Figure 1 shown.

[0023] The adaptive virtual reality training module is the basis of this system, which includes a scene construction unit, an interaction design unit, and an adaptive learning algorithm unit. The scene construction unit uses the Artec Leo high-precision 3D scanner to capture the real medical environment with a resolution of 0.2mm. The collected 3D data is processed and rendered through the Unity 2022.3LTS engine. At the same time, the unit uses procedural generation technology to dynamically create diverse ward scenes to provide a more realistic and varied training environment. The interaction design unit integrates the Leap Motion Controller to achieve hand tracking with an accuracy of 0.1mm, and uses the HaptXGloves DK2 tactile feedback gloves to provide 16 touch points and finger resistance feedback to enhance the realism of the operation. The adaptive learning algorithm unit realizes intelligent training content adjustment, the core of which is the Upper Confidence Bound (UCB) algorithm, the formula is as follows:

[0024]

[0025] Among them, a t represents the action (training content) selected at time step t, is the estimated value of action a, c is the exploration parameter that controls the balance between exploration and exploitation, t is the current time step, and N t (a) is the number of times action a is selected. This algorithm can effectively balance known high-value content and under-explored content, thereby optimizing the learning experience.

[0026] The multimodal artificial intelligence evaluation module is the core evaluation component of the system, which includes a visual analysis unit, a speech analysis unit, and a motion analysis unit. The visual analysis unit uses the YOLOv5s model for real-time object detection with a processing speed of 30FPS, and uses ResNet152 for posture estimation with an accuracy of 95%. The speech analysis unit uses the Wav2Vec 2.0 model for speech recognition with an error rate of less than 5%, and implements a BERT-based Chinese medical field fine-tuning model to accurately understand medical terminology. The motion analysis unit uses the OpenPose framework for skeleton point tracking and supports real-time detection of 25 key points. The motion similarity calculation uses the Dynamic Time Warping (DTW) algorithm, and its core recursive formula is as follows:

[0027]

[0028] In this formula, DTW(i,j) represents the DTW distance between the first i elements of sequence X and the first j elements of sequence Y, d(x i ,y j ) is an element x i andj The distance metric between i is the i-th element in the student's action sequence, y j is the jth element in the canonical action sequence. This algorithm can effectively compare action sequences of different lengths and provide accurate similarity assessment.

[0029] The quantum encryption biometric module ensures the security of the system. It includes a quantum key distribution unit, a multimodal biometric unit and an anti-spoofing mechanism unit. The quantum key distribution unit implements a continuous variable quantum key distribution (CV-QKD) protocol, using Gaussian modulated coherent states, with a transmission distance of 100km. The multimodal biometric unit uses a deep learning model based on the ResNet-50 architecture to fuse fingerprints, irises, facial features, electrocardiogram (ECG) and electroencephalogram (EEG) data to provide multi-dimensional identity authentication. The anti-spoofing mechanism unit uses deep pixel-level depth map reconstruction technology, based on the U-Net++ architecture to prevent flat photo attacks, and implements a liveness detection system based on the FLIRRepton3.5 thermal imaging sensor to effectively prevent various deception methods.

[0030] The distributed ledger record module ensures the reliable storage and management of data. It includes a directed acyclic graph structure optimization unit, a smart contract unit, and a data management unit. The directed acyclic graph structure optimization unit is based on the improved IOTATangle2.0 protocol and uses the MCMC (MarkovChainMonte Carlo) random walk algorithm for node selection. The transfer probability formula is as follows:

[0031]

[0032] In this formula, P(i→j) represents the probability of transferring from node i to node j, and W ij is the weight of node i to node j (usually based on the number of transaction confirmations and age), is the weight sum of all outgoing edges of node i. This algorithm selects nodes by random walk, which helps to achieve fast and decentralized consensus. The smart contract unit uses the WebAssembly (Wasm) virtual machine, supports multi-language smart contract development, and improves execution efficiency by 30%. The data management unit uses a star topology to store relevant research and case data, and the central node uses high-performance SSD storage to ensure efficient access and management of data.

[0033] The AI-assisted decision-making and risk warning module is the intelligent decision-making center of the system, which includes a causal reasoning engine unit, a federated learning framework unit, and a real-time monitoring unit. The causal reasoning engine unit uses the PC algorithm for structural learning, automatically discovers the causal relationship between variables, and implements causal effect estimation based on double machine learning, providing reliable theoretical support for decision-making. The federated learning framework unit adopts the FATE (Federated AI Technology Enabler) framework, supports horizontal and vertical federated learning, and uses homomorphic encryption technology to protect the model parameter transmission process, realizing model optimization under the premise of protecting privacy. The real-time monitoring unit uses the Farneback optical flow estimation algorithm to analyze the hand movement trajectory with sub-pixel accuracy, and implements abnormal behavior detection based on the behavior tree to provide real-time risk warnings.

[0034] This nasoenteric tube placement qualification certification and review system has built a comprehensive, intelligent and secure medical training and certification platform by integrating advanced virtual reality, artificial intelligence, quantum encryption, distributed ledger and real-time monitoring technology. The main innovations and advantages of the system are reflected in the highly personalized adaptive learning system, all-round objective multimodal AI evaluation, theoretically absolutely safe quantum encryption technology, DAG structure distributed ledger that supports high concurrent operations, and reliable risk assessment based on causal reasoning. Through the synergy of these innovative technologies, this system can comprehensively improve the quality of medical training, certification reliability and operational safety, and provide better medical protection for patients. At the same time, the modular design of the system also facilitates future expansion and upgrading, and can be continuously optimized and improved according to the development of medical technology and new needs.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
