[0044] Among them, the data acquisition module is mainly used to collect real-time data of the stoma; the intelligent analysis module is used to analyze the user's care habits and real-time data through machine learning algorithms; the VR guidance module is used to provide step-by-step virtual visualization guidance for stoma care through virtual reality technology; the voice interaction module is used to guide the user to replace the stoma bag and handle abnormal conditions of the stoma and the surrounding skin through voice commands; the personalized care module is used to provide targeted care suggestions according to individual differences and save the care suggestions to the personalized care knowledge base; the remote care module is used to connect the mobile phone client to the hospital medical record system and send and receive remote consultation instructions from stoma care experts.

[0045] The functions of each module are introduced in sequence as follows:

[0046] The data acquisition module is used to collect real-time data of the stoma and transmit the real-time data to the intelligent analysis module. The real-time data includes stoma status and environmental data.

[0047] Among them, the stoma status includes stoma shape, stoma size, stoma color, and excrement characteristics (such as shape, quantity, etc.). In this embodiment, the stoma status is collected by the camera 1 and analyzed using image processing technology; the environmental data includes temperature, humidity, and pH value. In this embodiment, the environmental data is collected by means of a sensor array.

[0048] The intelligent analysis module is used to obtain real-time data, connect to the mobile phone client, analyze the user's nursing habits and real-time data through machine learning algorithms, generate an intelligent reminder for changing the ostomy bag, and use the buzzer 4 for intelligent reminder in this embodiment; output the analysis results of ostomy care.

[0049] Specifically, the intelligent analysis module establishes a patient individual baseline model and an anomaly detection and recognition model through machine learning algorithms. In this embodiment, the machine learning algorithm is trained using a decision tree model; the individual baseline model includes identifying the nursing processes for different stoma treatments, dynamically adjusting suggestions (such as for ileostomy with high-frequency excretion, the replacement cycle needs to be shortened), processing keyword suggestions, and a risk prediction model; predicting the best practices for stoma care or identifying potential risk factors (such as dermatitis or leakage probability) based on the patient's historical data (such as pH value fluctuations or excrement quantity, excretion frequency, etc.). The anomaly detection and recognition model includes quantitative analysis of excrement color and quantity, and changes in the morphology of the skin around the stoma (such as protrusions or depressions, etc.).

[0050] The VR guidance module is used to provide step-by-step (such as operations like stoma baseplate cutting, pasting, and cleaning, etc.) virtual visualization guidance for stoma care according to the analysis results output by the intelligent analysis module; in this embodiment, the virtual visualization guidance is provided using the VR glasses 2, and the VR glasses 2 are used to be worn on the user's head; the indicator light 3 is integrated on the VR glasses 2 to facilitate indication during virtual training; and provide light-assisted indication for virtual training; obtain the virtual training results.

[0060] The personalized care module is used to provide targeted care suggestions based on individual differences according to the ostomy bag replacement and abnormal condition processing results of the voice interaction module. The care suggestions include ostomy care plans (such as "the humidity is relatively high today, it is recommended to check the tightness of the ostomy chassis"), abnormal condition suggestions, and daily life precautions for ostomy care (such as a low-fiber diet or avoiding exercises that increase abdominal pressure); and save the care suggestions to the personalized care knowledge base.

[0061] Among them, the personalized care module includes the following units:

[0062] The dynamic update unit is used to dynamically update the personalized care knowledge base, and associate the keywords for abnormal condition handling (such as "redness", "odor", or "high discharge", etc.) with the corresponding care suggestions (such as home treatment, pressing, or emergency medical treatment, etc.).

[0063] The personalized suggestion unit is used to provide a personalized guidance plan based on individual differences; the individual differences include stoma type (such as temporary, permanent, location, or shape, etc.), body shape, living habits, and the ostomy products used.

[0064] The environmental advice unit is used to provide environmental adaptability advice, and the environmental adaptability advice includes recommending the ostomy chassis material and the pasting duration of the ostomy chassis according to temperature and humidity.

[0065] The remote care module is used to connect the mobile phone client to the hospital database and send and receive remote consultation instructions from ostomy care experts.
