Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation and nutritional intervention, and specifically to a monitoring and nutritional intervention system for children during postoperative intestinal function recovery, which belongs to a cross-application system of intelligent medical care and health management. Background Art

[0002] After abdominal surgery, children often experience postoperative reactions such as intestinal dysfunction and decreased digestion and absorption capacity. Management during the recovery period requires a balance between physiological status monitoring and nutritional support. However, existing clinical management methods mostly rely on manual observation and experience to formulate recipes, lacking personalized nutritional intervention plans based on systematic data support, making it difficult to respond to changes in children's physical signs in a timely manner. In addition, during postoperative care, the implementation of nutritional intake and children's reactions are difficult to quantify and record, and the feedback mechanism is imperfect, resulting in variability and uncertainty in the effectiveness of interventions.

[0003] Although some hospitals have introduced intelligent health management platforms in recent years, specialized monitoring and nutritional optimization mechanisms for postoperative intestinal function recovery in children remain incomplete, particularly with regard to the comprehensiveness of data collection, the adaptability of evaluation mechanisms, and the intelligence of feedback loops. Therefore, there is an urgent need to develop a system specifically for postoperative children that integrates multidimensional data analysis and nutritional intervention implementation support to achieve intelligent management and optimization of postoperative intestinal function recovery.

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0047] refer to Figures 1-6 The embodiment of the present invention provides a system for monitoring and nutritional intervention of postoperative intestinal function in children, including the following modules:

[0048] The data collection module is used to collect physiological data, symptom manifestations and dietary intake records related to children's postoperative intestinal function.

[0049] The data collection module includes a physiological data collection unit, a dietary record unit, and a symptom feedback unit. These three work together to comprehensively collect and record the child's postoperative recovery status. This module is used to comprehensively obtain multi-dimensional data related to the child's postoperative intestinal function recovery and upload it wirelessly and in real time to the system's central database to support subsequent status assessment and intervention decisions.

[0050] The physiological data collection unit integrates wearable sensor devices and bedside monitoring equipment to collect children's key physiological indicators in real time or at regular intervals. The collected indicators include:

[0051] (1) Bowel sound frequency: The number of bowel sounds per unit time is automatically detected using an electronic stethoscope module or micro-vibration detection module placed on the surface of the abdomen;

[0052] (2) Defecation frequency: combining toilet sensor equipment and manual input from family members to record the number and time of daily defecation;

[0053] (3) Abdominal distension and abdominal tenderness data: The abdominal distension status is monitored by a surface impedance change monitor, and the local tenderness response area and sensitivity are obtained in combination with a soft pressure feedback pad;

[0054] (4) Changes in body temperature and weight: Use a Bluetooth thermometer and an electronic scale to record body temperature and weight fluctuations daily to facilitate the judgment of postoperative recovery trends.

[0055] The diet record unit provides an interactive recording interface based on the mobile app for recording children's daily diet intake information. This includes the types of nutrients contained in each meal (such as the intake of protein, fat, carbohydrates, etc.), the number of meals, the type of food (such as liquid food, solid food, etc.) and the total daily water intake. The system has a built-in nutrient database. After the user enters the food, the ingredient recognition and nutrient calculation are automatically completed, improving the entry efficiency and accuracy.

[0056] The symptom feedback unit is open to children and their guardians. It uses a combination of graphical questionnaires and text descriptions to facilitate children's description of their subjective postoperative discomfort. Typical postoperative symptoms such as nausea, vomiting, abdominal pain, loss of appetite, and bloating can be entered. Each record is timestamped to facilitate subsequent comparison and analysis with physiological data.

[0057] All collected data is automatically transmitted to a central database via Wi-Fi or ZigBee modules, along with a high-precision timestamp. The system standardizes the data into a structured dataset, supporting subsequent recovery modeling and personalized intervention recommendations, while also meeting the needs of long-term follow-up and trend prediction.

[0058] The status assessment module is used to comprehensively assess the recovery of children's intestinal function based on the collected data.

[0059] In the status assessment module, this module includes a data standardization processing unit, a status scoring unit, and a graded diagnosis unit. This module is used to uniformly process, objectively quantify, and comprehensively grade the collected multi-source heterogeneous health data, thereby providing a scientific and real-time basis for the subsequent generation of nutritional intervention strategies.

[0060] First, the data standardization processing unit receives the raw data uploaded from the data acquisition module, including physiological parameters (such as bowel sound frequency, body temperature, weight changes, etc.), dietary records (such as nutrient intake, water intake, etc.) and subjective symptom feedback (such as nausea, bloating, vomiting, etc.). For different data types, the unit uses a preset standardized template to unify all data into a comparable format. For example, the bowel sound frequency is converted into times per minute, the dietary intake information is converted into daily total calories and nutrient ratios, and the missing data is filled in using time series interpolation or average substitution to ensure data integrity and consistency.

[0061] Afterwards, the status scoring unit quantifies and scores the standardized key data based on the clinically defined postoperative recovery evaluation scale. Scoring indicators cover the core characteristics of intestinal function recovery, such as whether bowel sounds have returned to baseline levels, whether bowel movements are regular, and the presence and frequency of typical discomfort symptoms. Each indicator corresponds to a clear scoring level, and the system automatically generates a comprehensive scoring report based on the latest round of collected data. This score not only reflects the current recovery status, but can also be compared with previous data to generate trend judgments.

[0062] Finally, the graded diagnosis unit uses the comprehensive score output by the scoring unit and the association rules of multiple indicators to grade the child's current intestinal function status. The system has three grading standards: good recovery (score meets the standard, symptoms are mild), delayed recovery (slightly low score, mild to moderate symptoms), and intervention required (low score, obvious symptoms or stagnant recovery). Each assessment result will serve as an input trigger condition for the nutritional intervention module, directly used to generate corresponding nutritional adjustment recommendations and intervention paths.

[0063] Nutrition intervention module, used to generate personalized nutrition intervention plans based on the assessment results.

[0064] In the nutritional intervention module, this module includes an intervention plan generation unit, a recipe recommendation unit and a metabolic adjustment suggestion unit. This module is used to intelligently formulate personalized, dynamically adjustable postoperative nutritional support strategies based on the recovery level output by the status assessment module, and push them to medical staff and guardians through mobile terminals to assist in precise intervention.

[0065] After receiving the assessment results from the status assessment module, the intervention plan generation unit first generates a recommended daily intake range of core nutrients based on the child's current status (e.g., good recovery, delayed recovery, intervention required) and the basal metabolic needs of the child's age group. This recommended plan covers five major categories of nutrients: protein, carbohydrates, fat, dietary fiber, and probiotics. The system automatically adjusts the proportions of each ingredient based on past dietary records and recovery trends to ensure that postoperative recovery needs are met while avoiding excessive intestinal burden.

[0066] The recipe recommendation unit further decomposes the generated nutritional recommendations into a structured manner, and combines the child's preset individual information in the system (such as age, height, weight), taste preferences (such as avoid spicy food, prefer sweet food), and previously entered allergies and taboo ingredients (such as lactose intolerance, nut allergy) to generate three-meal recipe recommendations. Each recipe includes a combination of staple food, complementary food, vegetables and drinks, and displays the nutritional content label in a graphical interface, so that guardians can clearly understand the nutritional ratio and total calories of each meal when preparing meals. It also supports substitution and recommendation functions for easy personalized adjustments.

[0067] When the system identifies symptoms such as decreased appetite, frequent bloating, or diarrhea in a child, the metabolic adjustment suggestion unit automatically triggers an intervention mechanism. Based on the child's current digestion and absorption capacity and symptom records, it outputs structured dietary adjustment suggestions, including whether to temporarily adopt a liquid diet, introduce more easily digestible high-energy foods (such as rice soup and vegetable puree), or implement a separate dining system (such as eating every two hours to reduce gastrointestinal burden). The unit can also dynamically modify intervention suggestions based on guardian feedback to ensure the effectiveness and individual adaptability of the intervention.

[0068] The intervention execution and recording module is used to assist medical staff in implementing the intervention plan and recording the intervention process and children's responses.

[0069] In the intervention execution and recording module, this module consists of three parts: execution guidance unit, intervention feedback recording unit and automatic comparison and analysis unit, which work together to complete the closed-loop management process from execution to feedback.

[0070] First, the execution guidance unit pushes the personalized dietary recommendations pushed by the nutritional intervention module and pushes the detailed implementation steps of three meals a day to the guardian or caregiver in the form of a calendar plan. The steps include a list of required ingredients, recommended eating order (for example, eating staple food first and then supplementing with vegetables and protein foods), and meal time recommendations (such as recommending that each meal take no less than 20 minutes to facilitate digestion), etc., aiming to standardize postoperative dietary behavior and improve the operability of the intervention plan.

[0071] During implementation, the intervention feedback recording unit receives real-time information from guardians via a mobile device or medical workstation interface, including the child's actual food ingredients and quantity, appetite, any negative reactions such as vomiting and diarrhea, and changes in vital signs such as temperature, pulse, and mental state. The unit supports voice input and image-assisted recognition, lowering the threshold for family record keeping and improving the completeness and accuracy of data collection.

[0072] Subsequently, the automatic comparison and analysis unit compares and analyzes the collected actual eating data with the system's recommended intake plan, and quantifies the child's current diet implementation using a preset eating suitability scoring formula, which is as follows:

[0073]

[0074] Among them, A i represents the actual intake value of the ith nutrient, T i is the recommended intake value for item i, W i is the importance weight coefficient of the i-th nutrient, n is the total number of nutrients, and S is the final suitability score. This score ranges from 0 to 1, with higher values indicating a greater match between actual intake and the recommended plan. The system can set thresholds based on the score, providing prompts such as "met," "almost met," or "needs adjustment," to guide medical staff in fine-tuning the intervention plan.

[0075] Feedback optimization module, used to continuously optimize nutritional intervention strategies and intestinal function recovery paths based on intervention results.

[0076] In the feedback optimization module, this module includes three functional units: response analysis unit, strategy evaluation unit and solution fine-tuning unit. The units form a sequentially connected and logically closed processing flow.

[0077] First, the Response Analysis Unit receives data from the Intervention Execution and Recording Module and focuses on analyzing physiological monitoring data and subjective symptom feedback collected within 72 hours of the intervention. Key analysis indicators include whether changes in bowel sound frequency have stabilized, whether bowel movement frequency has returned to its preoperative rhythm, whether abdominal distension has decreased, and whether body temperature remains within a normal range. This unit also assesses early signs of intervention response, combining subjective feedback from children or guardians regarding nausea, abdominal pain, and vomiting.

[0078] Next, the strategy evaluation unit summarizes and determines the above analysis results to determine whether the current nutritional intervention strategy has achieved the expected goals. If the system detects that the eating adaptability score is continuously low, the bowel movements are abnormal, the abdominal distension is aggravated, or the subjective symptoms are not significantly relieved, the system will determine that the current strategy is not effective. In particular, when the intestinal function score shows a downward trend compared to the previous period, the system will trigger a strategy reassessment prompt to provide basic support for the adjustment of the plan.

[0079] Finally, the plan fine-tuning unit will make parameter-level adjustments based on existing dietary intervention recommendations. For example, based on the child's response to dietary fiber intake, it may moderately reduce crude fiber intake and increase the proportion of soft vegetables. If symptoms suggest indigestion, it may also recommend the supplementation of specific probiotics or adjust the proportion of lactose-rich foods. The fine-tuning plan will be pushed to the guardian and medical staff's terminals in the form of structured data, and a new three-day recommended diet and precautions will be provided, enabling the system to individualize and dynamically manage the child's postoperative intestinal function recovery.
