Description

Technical Field

[0001] This invention belongs to the field of smart medical technology, specifically relating to a monitoring and individualized energy demand management system for energy consumption during childbirth. Background Technology

[0002] In current clinical delivery management scenarios, the monitoring of maternal energy consumption and the management of energy replenishment during labor face many key challenges, seriously affecting delivery quality and maternal and infant safety:

[0003] 1. Insufficient monitoring accuracy: Current clinical practice mainly relies on the experience of medical staff to estimate the energy consumption of postpartum women. There is a lack of accurate monitoring equipment that can capture the dynamic changes in the labor process in real time, which leads to a significant deviation between energy consumption assessment and actual needs, and cannot provide a scientific basis for nutritional intervention.

[0004] 2. Individual differences are ignored: There are significant individual differences in basal metabolic rate, labor progress speed, physical strength reserve level and stress response among different mothers. However, existing technologies mostly adopt standardized assessment models, making it difficult to develop appropriate energy demand plans based on individual characteristics, resulting in frequent problems of insufficient or excessive supplementation.

[0005] 3. Delayed and rigid nutritional supplementation: Traditional nutritional supplementation plans are mostly fixed templates that cannot be dynamically adjusted according to the mother's real-time energy consumption data and the stage of labor. This often results in a disconnect between energy supplementation and actual needs, making it difficult to effectively support the mother's physical exertion during childbirth.

[0006] 4. Difficulty in integrating multi-dimensional data: Energy consumption during childbirth is closely related to multiple physiological parameters such as heart rate, respiration, uterine contraction intensity, body temperature, and activity level. Existing technologies lack the ability to efficiently integrate and analyze multi-source data in real time, making it impossible to comprehensively and systematically assess energy consumption status.

[0007] 5. Lack of risk warning mechanism: When the mother experiences risks such as insufficient energy reserves, excessive consumption or metabolic disorders, the existing system cannot identify and issue warnings in a timely manner, nor can it conduct scientific risk level assessments. This may lead to increased maternal fatigue, prolonged labor, or even affect maternal and infant safety. To address this, we propose an energy consumption monitoring and individualized energy demand management system for the childbirth process. Summary of the Invention

[0008] The purpose of this invention is to provide a monitoring and individualized energy demand management system for energy consumption during childbirth, enabling real-time and accurate monitoring of energy consumption during childbirth, prediction of individualized energy demand, and dynamic nutritional supplementation. At the same time, it constructs a multi-level early warning mechanism to effectively solve problems such as insufficient accuracy, poor individual adaptability, and delayed supplementation in traditional management.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a monitoring and individualized energy demand management system for labor process energy consumption, comprising a multimodal perception layer, a transmission layer, a computing layer, and an application decision layer. The multimodal perception layer includes a multimodal data acquisition module and a non-invasive metabolic monitoring module. The multimodal data acquisition module uses a wearable sensor array to collect various physiological parameters of the pregnant woman. The non-invasive metabolic monitoring module collects tissue oxygenation data, body fluid distribution and metabolic data, and oxygen consumption and carbon dioxide production data. The transmission layer integrates the data collected by the multimodal perception layer through a gateway device and encrypts and transmits the integrated data to the computing layer. The computing layer establishes an individual basal metabolic rate (BMR) model through an intelligent computing module and calculates the total energy consumption during labor. Then, it calculates the balance state through a dynamic energy demand prediction model. The application decision layer generates individualized nutritional supplementation plans based on the data from the computing layer, triggers multi-level early warnings, and pushes clinical decision suggestions. Data visualization, operation feedback, and collaborative management of the labor process are achieved through medical / nursing / partner terminals.

[0010] Preferably, the wearable sensor array includes a heart rate variability sensor (HRV), a respiratory rate and depth sensor, a skin temperature and core body temperature sensor, an electromyography (EMG) sensor, and a motion acceleration sensor.

[0011] Preferably, the non-invasive metabolic monitoring module includes a near-infrared spectroscopy sensor, an impedance analyzer, and a micro gas exchange sensor.

[0012] Preferably, the steps for establishing the individual basal metabolic rate (BMR) model are as follows:

[0013] S1. Input parameters: Mother's height, age, current weight, pre-pregnancy BMI, gestational weight gain, and fetal ultrasound development parameters;

[0014] S2. Substitute the base value into the BMR formula and dynamically adjust it through the individual correction coefficient K to obtain the personalized BMR value;

[0015] S3. Calculate the total energy consumption during labor. .

[0016] Preferably, the BMR formula is:

[0017] ;

[0018] In the formula: W is the mother's current weight, H is the mother's height, A is the mother's age, and K is the individual correction coefficient.

[0019] Preferably, the total energy consumption of the production process The calculation formula is as follows:

[0020] ;

[0021] In the formula: Basic metabolic energy consumption, Energy consumption for uterine contractions Energy consumption for breathing For thermal regulation energy consumption, For activity energy consumption, This is for stress-related energy consumption.

[0022] Preferably, the dynamic energy demand prediction model is as follows:

[0023] Total energy consumption during labor Input is fed into an LSTM neural network model, which outputs a predicted energy demand value for the next 1-2 hours. The formula is as follows:

[0024]

[0025] In the formula: For long short-term memory neural network models, This is a historical energy consumption sequence for the production process. This is the feature vector of labor progress. It is an individual physiological characteristic vector (including personalized BMR, energy reserve rate, and fatigue risk level). This is a feature fusion operation (concatenating multi-dimensional data into an LSTM input vector). The correction factor for the labor stage is 1.0 for the first stage of labor, 1.2 for the second stage, and 0.8 for the third stage, to adapt to the differences in energy consumption intensity at different stages of labor.

[0026] Preferably, the application decision layer calculates cumulative energy consumption based on real-time statistics. With cumulative energy intake Calculate the energy gap Assess energy reserve rate (energy converted from glycogen and fat), and determine fatigue risk level based on energy deficit and reserve rate; optimize nutrient ratio based on predicted energy demand, maternal digestive and absorptive capacity (medical history collection), dietary preferences, and stage of labor progress, and based on predicted energy demand. The infusion system automatically adjusts the infusion rate.

[0027] Preferably, the energy gap The calculation formula is:

[0028] .

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) Through the wearable sensor array and non-invasive metabolic monitoring module of the multimodal perception layer, the data of the parturient physiological signs, tissue oxygenation, body fluid metabolism and gas exchange are collected in a comprehensive manner. Combined with the data cleaning and standardization processing of the transmission layer, the limitations of traditional experience estimation are broken through, and the real-time and accurate quantification of energy consumption during labor is realized, providing reliable data support for subsequent energy management.

[0031] (2) Based on individual parameters such as the mother's height, age, weight, and pre-pregnancy BMI, a personalized basal metabolic rate (BMR) model is established through an intelligent computing module. Combined with the characteristics of labor progress and individual physiological reserves, the predicted energy demand value is dynamically generated. At the same time, taking into full account the mother's digestive and absorption capacity, dietary preferences, and other factors, a differentiated nutritional supplementation plan is formulated, which completely solves the problem of neglecting individual differences in traditional standardized plans.

[0032] (3) Based on the LSTM neural network model, the energy demand for the next 1-2 hours is predicted. The decision-making layer is linked with the precision infusion system and the postpartum terminal to realize the automatic adjustment of the intravenous infusion rate and the intelligent reminder of oral nutritional supplementation. Through real-time calculation of energy deficit and assessment of reserve rate, the nutrient ratio (precise proportion of carbohydrates, protein and fat) is dynamically optimized to ensure that energy supplementation is dynamically matched with the energy consumption of labor and effectively maintain the postpartum woman's physical strength.

[0033] (4) Establish an energy balance monitoring mechanism and a multi-level early warning system. Through comprehensive assessment of energy deficit, reserve rate and metabolic indicators, accurately determine the fatigue risk level, trigger yellow, orange and red three-level early warnings and push targeted decision-making suggestions. At the same time, through the visual interaction between medical staff terminals and maternal terminals, realize the real-time sharing of physiological data, energy consumption status, nutrition plan and early warning information, help medical staff and maternal patients to jointly manage the labor process, and reduce problems such as prolonged labor and maternal and infant risks caused by insufficient energy.

[0034] (5) Integrating physiological parameters, energy consumption data, nutritional program implementation status, and early warning records throughout the entire labor process forms a traceable and complete data chain. This not only provides closed-loop support for individual childbirth management but also accumulates rich data for clinical research, promoting the transformation of labor energy management from experience-based to scientific and intelligent.
