Description

Technical Field

[0001] The present invention belongs to the field of medical technology, and in particular relates to an efficient obstetric midwifery technical method and system. Background Art

[0002] Existing midwifery methods often rely too much on the experience and techniques of midwives, lacking in systematicness and scientificity. For example, the assessment of the maternal physical condition is not comprehensive and accurate enough, and may not fully combine advanced imaging technology and psychological scale assessments, making it difficult to accurately grasp key factors such as pelvic morphology, fetal size and fetal position, and maternal psychological state, resulting in inaccurate predictions of the difficulty of delivery. At the same time, during the delivery process, there is a lack of scientific basis for monitoring and guiding the maternal force, and it is impossible to accurately analyze the force pattern in real time, which can easily lead to maternal physical waste and low delivery efficiency. In addition, fetal monitoring is not comprehensive and real-time enough, and there may be omissions in the monitoring of important indicators such as fetal heart rate, fetal movement, amniotic fluid volume, and umbilical cord blood flow, and targeted intervention measures cannot be taken in a timely and effective manner when abnormalities are found. Moreover, the existing midwifery system has defects in information integration and interaction, and cannot provide comprehensive, accurate, and real-time decision-making support for medical staff, affecting the quality of midwifery and maternal and child safety.

[0003] In order to solve the above problems, the present invention provides an efficient obstetric midwifery technical method and system. The method and system are intended to improve the efficiency and quality of obstetric midwifery and ensure the safety of mother and baby through comprehensive and accurate maternal physical condition assessment, scientific labor force monitoring and guidance, real-time and comprehensive fetal monitoring and effective intervention, and a complete information integration and interactive system.

Based on the comprehensive physical condition assessment results, medical staff can adjust the midwifery strategy in a timely manner according to the actual situation of the parturient. For example, when it is found that the parturient is under too much psychological pressure, psychological counseling measures such as music therapy and breathing relaxation training are used to help the parturient relieve tension and improve her cooperation in delivery, which is conducive to the smooth progress of the delivery process.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] The present invention provides the following technical solutions:

[0028] An efficient obstetric midwifery technical method, characterized by comprising the following steps:

[0029] S1. Conduct a comprehensive physical assessment of the mother, including assessment of factors such as pelvic morphology, fetal size, and fetal position, using a combination of imaging technology and physical examination; at the same time, monitor the mother's physiological indicators and psychological state in real time, and adjust the midwifery strategy based on the monitoring results.

[0030] S2. Based on the principles of biomechanics, sensors are used to collect real-time data on the force applied by mothers during childbirth, including the direction, strength, duration, etc. of the force applied. The force pattern of the mothers is analyzed based on the collected data, and real-time feedback and guidance are provided to the mothers and midwives through a visual interface. The force pattern analysis can be carried out using the following formula: F=ma (where F represents force, m represents a quality parameter related to the force applied by the mother, and a represents acceleration, which is calculated using data collected by sensors and is used to evaluate the effectiveness and rationality of the force applied).

[0031] S3. Use continuous fetal heart rate monitoring technology and fetal ultrasound examination to monitor the fetal condition in real time. When fetal abnormalities are found, the early warning mechanism is automatically activated and treatment suggestions are provided according to the preset intervention plan.

[0032] In a specific embodiment of the present invention, step S1: comprehensive physical condition assessment of the parturient and adjustment of the midwifery strategy:

[0033] Physical condition assessment: Using advanced imaging technology (such as 3D ultrasound) combined with physical examination, a comprehensive assessment of the mother's pelvic shape, fetal size, fetal position and other factors is conducted. For example, 3D ultrasound can be used to accurately measure the diameters of the pelvis to determine whether it is suitable for normal delivery; at the same time, the position and posture of the fetus in the uterus can be determined to estimate the difficulties that may be encountered during delivery.

[0034] Real-time monitoring of the mother's physiological indicators, including heart rate, blood pressure, respiratory rate, etc., as well as psychological state (assessed with the help of psychological scales). For example, during the delivery process, the mother's heart rate changes are continuously monitored to understand her physical tolerance; the mother's psychological stress level is regularly assessed through psychological scales.

[0035] Adjustment of midwifery strategy: According to the above physical condition assessment and monitoring results, the midwifery strategy should be adjusted in time. For example, if the psychological pressure of the parturient is too great, such as anxiety that obviously affects her cooperation, psychological counseling measures should be taken. For example, music therapy can be implemented to play soothing music for the parturient to help her relax her body and mind; or breathing relaxation training can be carried out to guide the parturient to breathe correctly and relieve tension to maintain a good delivery state.

[0036] Step S2: Monitoring and guidance of labor force based on biomechanical principles:

[0037] Force data collection:

[0038] Based on the principles of biomechanics, sensors (such as pressure sensors, electromyographic sensors, etc.) are used to collect real-time force data of mothers during childbirth. These data cover multiple aspects such as force direction, force, and duration. For example, when a mother exerts force, the pressure sensor accurately measures the pressure and distribution on the delivery bed, while the electromyographic sensor monitors the contraction force and frequency of the relevant muscles, thereby obtaining comprehensive force information.

[0039] Force mode analysis and feedback:

[0040] Based on the collected data, the force pattern of the parturient is analyzed using the formula F=ma (where F represents force, m represents the mass parameter related to the parturient's force, and a represents acceleration, which is calculated from the data collected by the sensor). For example, by processing the data of the pressure sensor and the electromyography sensor, the value of acceleration is calculated, and combined with the pre-set mass parameter related to the parturient's force, the magnitude and direction of the force are obtained.

[0041] Real-time feedback and guidance are provided to mothers and midwives through a visual interface (such as a display screen). If the analysis results show that the mother's force direction is deviated, the visual interface will promptly issue a prompt signal, such as displaying an arrow to indicate the correct force direction, to guide the mother to adjust the force direction, so as to improve delivery efficiency and reduce physical exertion of the mother.

[0042] Step S3: Fetal monitoring and abnormal intervention:

[0043] Fetal status monitoring:

[0044] Continuous fetal heart rate monitoring technology is used to monitor the fetal heart rate changes in real time. At the same time, combined with fetal ultrasound examination, the fetal movement, amniotic fluid volume, umbilical cord blood flow, etc. are observed to comprehensively evaluate the health of the fetus. For example, during delivery, the fetal heart rate curve is continuously recorded to observe whether there are abnormal conditions such as fetal heart rate deceleration; through ultrasound examination, check whether the amniotic fluid volume is normal and whether the umbilical cord blood flow is smooth.

[0045] Unusual interventions:

[0046] When an abnormal condition is found in the fetus (such as fetal heart rate deceleration, decreased fetal movement, etc.), the system automatically activates the early warning mechanism and provides corresponding treatment suggestions according to the preset intervention plan. For example, if the fetal heart rate deceleration is mild and lasts for a short time, the system will prompt and guide the mother to change her body position, such as lying on the left side, to improve fetal blood circulation; if the situation is more serious, such as the fetal heart rate deceleration lasts for a long time and the amplitude is large, the doctor will be notified in time for further examination and treatment, such as taking measures such as oxygen inhalation and intravenous infusion, and emergency cesarean section if necessary.

[0047] Specifically, this plan includes the midwifery system:

[0048] A data collection module is used to collect maternal physiological data, fetal monitoring data, and labor force data;

[0049] The data analysis and processing module cleans, analyzes and mines the collected data to extract valuable information;

[0050] The decision support module provides medical staff with personalized midwifery plans and decision-making suggestions based on the analysis results;

[0051] The user interaction module provides a friendly operating interface, making it convenient for medical staff and mothers to input and query information, and receive feedback and prompts from the system.

[0052] In this embodiment: Data acquisition module:

[0053] Maternal physiological data parameters: Vital signs parameters:

[0054] Heart rate: The normal range is generally 60-100 beats / minute, which is collected by a heart rate monitor and used to assess the mother's heart function and physical stress state.

[0055] Blood pressure: includes systolic pressure and diastolic pressure. The normal systolic pressure range is 90-140 mmHg, and the diastolic pressure range is 60-90 mmHg. It is measured with an electronic sphygmomanometer and reflects the condition of the mother's cardiovascular system.

[0056] Respiratory rate: The normal respiratory rate of an adult is 12-20 times / minute. By collecting data through a respiratory sensor, we can understand the respiratory function and body metabolism of the mother.

[0057] Other physiological parameters: Body temperature: The normal body temperature range is around 36-37.2℃, measured with a thermometer. Abnormal body temperature may indicate infection and other problems.

[0058] Blood oxygen saturation: It should generally be maintained at 95%-100%. It is collected through a blood oximeter and reflects the oxygen content in the mother's blood. It is crucial for evaluating the mother's respiratory and circulatory function.

[0059] Fetal monitoring data parameters:

[0060] Fetal heart parameters: Fetal heart rate: The normal range is 110-160 beats / minute. It is continuously monitored by a fetal heart monitor. Changes in fetal heart rate can reflect the fetal heart function and intrauterine condition.

[0061] Fetal heart rate variability: including short-term variability and long-term variability, is an important indicator for evaluating the function of the fetal autonomic nervous system and intrauterine reserve capacity. Normal short-term variability is generally between 6-25 times / minute, and long-term variability uses a specific algorithm to analyze the fluctuation of fetal heart rate.

[0062] Ultrasound examination parameters:

[0063] Fetal biparietal diameter: refers to the length of the widest part between the left and right sides of the fetal head. It is measured by ultrasound and can be used to assess whether the size of the fetal head is consistent with the gestational age and predict the mode of delivery. The fetal biparietal diameter has a corresponding normal range value at different gestational ages.

[0064] Fetal femur length: It is the length of the fetal thigh bone and is also one of the important indicators of ultrasound examination. It is used to evaluate the growth and development of the fetus. Its normal range increases with the increase of gestational age.

[0065] Amniotic fluid volume: measured by ultrasound assessment of the amniotic fluid index (AFI) or the maximum amniotic fluid depth. The normal range of the amniotic fluid index is between 5-25cm, and the maximum amniotic fluid depth is between 2-8cm. Too much or too little amniotic fluid may affect fetal development and the delivery process.

[0066] Umbilical cord blood flow parameters: including the ratio of the peak systolic velocity to the end-diastolic velocity of the umbilical artery blood flow (S / D ratio). In normal late pregnancy, the S / D ratio should be less than 3. It reflects the blood perfusion of the placenta and is of great significance for determining whether the fetus is at risk of hypoxia.

[0067] Labor force data parameters:

[0068] Force direction parameter: The force direction information collected by sensors (such as pressure sensors, electromyography sensors, etc.) is expressed in angles or three-dimensional coordinate directions and is used to determine whether the force applied by the mother meets the mechanical requirements of delivery.

[0069] Force parameter: The force generated by the force, the unit can be Newton (N). The pressure is measured by a pressure sensor and converted into the corresponding force to understand the intensity of the force applied by the mother.

[0070] Strain duration parameter: The duration of each strain exerted by the mother is recorded in seconds, which helps analyze the mother's physical exertion and strain rhythm.

[0071] Data analysis and processing module: Data cleaning parameters and indicators: Noise threshold: Set a reasonable noise threshold to identify and remove noise components in the collected data. For example, for small fluctuations or interferences that may occur during the collection of physiological data, if their amplitude is less than the set noise threshold, they are regarded as noise and removed.

[0072] Data analysis indicators:

[0073] Correlation analysis indicators: Calculate the correlation coefficients between different data parameters, such as the Pearson correlation coefficient, to determine which physiological data, fetal data, and labor force data are associated with each other, so as to better understand the interaction of various factors in the labor process.

[0074] Trend analysis indicators: Analyze the changing trends of maternal physiological data, fetal monitoring data and labor exertion data over time, such as observing the rising or falling trend of the maternal heart rate during labor, the changing trend of the fetal heart rate, and the changing trend of the maternal force and frequency, to provide a basis for midwifery decisions.

[0075] Data mining indicators:

[0076] Frequent pattern mining indicators: Algorithms are used to mine frequently occurring patterns in data. For example, in the maternal pushing data, is there a certain pushing pattern (such as a combination of pushing intensity and duration) that frequently appears during multiple births? This may suggest an effective way of pushing during childbirth.

[0077] Abnormal pattern recognition indicators: Set the recognition standards for abnormal patterns to detect abnormal patterns in fetal monitoring data, such as a sudden drop in fetal heart rate that lasts for a long time, or maternal physiological data that exceeds the normal range and persists abnormally, so as to issue early warnings in a timely manner.

[0078] Decision support module:

[0079] Midwifery program decision indicators:

[0080] Delivery risk assessment indicators: Comprehensively consider the results of the mother's physical condition assessment (such as pelvic shape, fetal size and fetal position), physiological data monitoring (such as whether the heart rate and blood pressure are stable) and fetal monitoring data (such as whether the fetal heart rate is normal, whether the amount of amniotic fluid is appropriate, etc.), and make a quantitative assessment of the delivery risk. For example, a delivery risk index is set, and the higher the value, the greater the delivery risk.

[0081] Indicators for selecting midwifery methods: Determine the appropriate midwifery method based on the results of the birth risk assessment and the specific conditions of the mother and fetus. For example, for low-risk mothers with good fetal conditions, natural delivery can be given priority; for mothers with certain risks but still with the possibility of natural delivery, assisted midwifery methods (such as the use of midwifery instruments, etc.) may be selected; for high-risk mothers or fetuses with serious abnormalities, cesarean section may be considered.

[0082] Decision suggestion generation indicators:

[0083] Intervention timing indicators: Determine when intervention measures are needed based on fetal monitoring data and maternal physical condition. For example, when the fetal heart rate drops abnormally and reaches a certain level, or when the maternal blood pressure fluctuates abnormally and lasts for a certain period of time, timely intervention suggestions are given, such as changing the maternal position, oxygen inhalation, etc.

[0084] Intervention intensity index: The intensity of intervention measures is determined according to the specific conditions of the fetus and the mother. For example, for mild fetal hypoxia, the mother may be advised to perform simple position changes and oxygen inhalation; for severe hypoxia, more intensive intervention measures may be required, such as intravenous infusion, emergency cesarean section, etc.

[0085] User interaction module:

[0086] Information display indicators:

[0087] Data update frequency: Set the update frequency of the data on the user interface. For example, physiological data is updated every 1-5 minutes, and fetal monitoring data may be updated every 1 minute depending on the performance of the monitoring equipment and actual needs.

[0088] - Updated every 2 minutes, labor force data is updated in real time to ensure that medical staff and mothers can obtain the latest information in a timely manner.

[0089] Information presentation method: Determine how data is presented on the interactive interface, such as displaying the changing trend of maternal physiological data in the form of charts (bar charts, line charts, etc.), displaying changes in fetal heart rate in the form of waveform charts, and displaying labor force data and system prompts and suggestions in a combination of numbers and text descriptions to facilitate users' intuitive understanding.

[0090] Operational convenience index:

[0091] Interface response time: measures the time it takes for the system to respond after the user performs an operation on the interactive interface (such as inputting information, clicking a button, etc.). Generally, the response time is required to be within 1-2 seconds to ensure smooth operation.

[0092] Degree of simplification of operation steps: Try to simplify the steps for users to perform various operations on the interactive interface (such as querying data, adjusting system settings, etc.), reduce unnecessary operation processes and menu levels, and improve the convenience and efficiency of user operations.

[0093] Specifically in this plan, during the comprehensive assessment before delivery, three-dimensional ultrasound is used to accurately measure the diameters of the pelvis, and a psychological scale is used to assess the psychological state of the mother.

[0094] In this embodiment: Three-dimensional ultrasound measurement of various pelvic diameters: Through three-dimensional ultrasound technology, the morphological and structural information of the pelvis can be clearly and accurately obtained, and the length of each pelvic diameter can be measured. These diameters include the anterior-posterior diameter and transverse diameter of the pelvic inlet, the anterior-posterior diameter and transverse diameter of the mid-pelvis, and the anterior-posterior diameter and transverse diameter of the pelvic outlet. The measurement results of the pelvic diameter are crucial for assessing whether the parturient has the conditions for natural childbirth. It can help medical staff understand whether the size and shape of the pelvis are suitable for the passage of the fetus, and predict possible difficulties during delivery, such as cephalopelvic disproportion. If the pelvic diameter is too small, other delivery methods such as cesarean section may need to be considered to ensure the safety of mother and child.

[0095] Specifically in this plan, when it is found that the mother is under too much psychological pressure, psychological counseling measures such as music therapy and breathing relaxation training are used to help her relieve tension.

[0096] In this embodiment: understanding the psychological state of the parturient helps medical staff to take targeted measures. The psychological state of the parturient during childbirth will directly affect the physiological response of her body and the degree of cooperation in childbirth. For example, excessive anxiety and fear may cause hormone imbalance in the parturient, affect uterine contraction, prolong the childbirth process, and even increase the risk of dystocia. Through psychological scale assessment, medical staff can promptly discover the psychological problems of the parturient and take corresponding psychological counseling measures before childbirth.

[0097] Specifically in this plan, during the fetal monitoring and intervention process, different treatment measures are taken according to the degree and duration of fetal heart rate deceleration, including guiding the mother to change body position, oxygen inhalation, intravenous infusion, and emergency cesarean section.

[0098] In this embodiment: music can stimulate the nervous system of the human body and regulate the endocrine system, thereby affecting the emotional state of the parturient. Soothing music can reduce the level of stress hormones in the parturient, such as adrenaline and cortisol, so that the parturient feels relaxed and calm. This relaxed state helps the parturient to better cope with the pain and discomfort during childbirth, improves her confidence and cooperation in childbirth, and the correct breathing method can regulate the body functions of the parturient. During childbirth, deep breathing and abdominal breathing can increase oxygen supply, reduce muscle tension, and relieve pain. At the same time, breathing relaxation training can help the parturient divert attention, reduce fear and concern about labor pain, make the parturient more focused on her own breathing and physical feelings, and improve her psychological and physiological tolerance.

[0099] Specifically in this solution, the sensor in the data acquisition module sends the collected data to the data analysis and processing module through wireless transmission technology.

[0100] In this embodiment: by improving the placental blood circulation, it is helpful to restore the normal heart rate of the fetus. This simple change of body position is usually the first measure to be taken when the fetus has an early mild abnormality. It can quickly relieve the hypoxia of the fetus without using drugs or performing invasive operations, and buy time for subsequent monitoring and treatment. Oxygen inhalation can increase the oxygen content in the mother's blood, thereby increasing the oxygen supply of the placenta and improving the hypoxia of the fetus. It is a common auxiliary treatment measure, which plays an important role in alleviating the abnormal heart rate of the fetus. Intravenous infusion can replenish the water and nutrients in the parturient's body, maintain the blood volume and blood pressure of the parturient, and also help to improve the blood circulation of the placenta, providing a better living environment for the fetus. In addition, for certain drug treatments (such as the use of tocolytics or drugs that promote fetal lung maturity, etc.), intravenous infusion is also a commonly used route of administration, and emergency cesarean section is a measure taken in an emergency to save the life of the fetus. Rapidly removing the fetus through surgery can avoid serious complications caused by long-term hypoxia in the fetus, such as brain damage, fetal distress, etc., to ensure the life safety of the fetus. At the same time, for mothers, possible life-threatening situations such as placental abruption can be dealt with in a timely manner.

[0101] Specifically in this solution, the decision support module generates midwifery plans and decision recommendations based on the knowledge base and clinical experience model.

[0102] In this embodiment: the knowledge base provides basic data support for the decision support module. After receiving the maternal and fetal related data from the data analysis and processing module, the information in the knowledge base can help the system quickly locate similar case situations and provide a reference for generating reasonable midwifery plans and decision-making recommendations. For example, if the maternal pelvic morphology data shows a flat pelvis, the relevant knowledge in the knowledge base about the delivery risks and treatment recommendations of a flat pelvis will be called to assist in subsequent decision-making;

[0103] The clinical experience model plays a core role in the decision support module. It evaluates and compares various possible midwifery plans based on the actual monitoring data of the current mother and fetus, combined with relevant knowledge in the knowledge base, using specific algorithms. For example, when a mother has fetal heart rate deceleration and mild hypertension, the clinical experience model will comprehensively consider these factors, weigh the risks and benefits of different delivery methods such as natural delivery, assisted delivery and cesarean section, and finally generate the most suitable midwifery plan and corresponding decision-making recommendations for the mother, such as recommending taking measures such as oxygen inhalation and changing the mother's position to observe for a period of time. If the situation does not improve, consider other delivery methods;

[0104] The touch screen design allows medical staff and mothers to easily interact with the midwifery system. Medical staff can quickly view the mother's basic information, physiological indicator monitoring data, fetal monitoring data, and system prompts and suggestions through the touch screen. At the same time, they can also easily set up and adjust the system, such as modifying the threshold of monitoring indicators and inputting special situation instructions for mothers. For mothers, the touch screen can display relevant information in a simple and easy-to-understand way, such as displaying the fetal heartbeat through a graphical interface, so that mothers can intuitively understand the status of the fetus and reduce psychological anxiety.

[0105] In this specific solution, the user interaction module adopts a touch screen design to display the basic information of the mother, physiological indicator monitoring data, fetal monitoring data, and system prompts and suggestions.

[0106] In this embodiment: This basic information is a very important reference for medical staff. It can help medical staff quickly understand the basic situation of the parturient and comprehensively consider these factors when formulating midwifery plans and making clinical decisions. For example, the age and parity of the parturient may affect the process and risks of delivery. Medical staff can prepare for possible problems in advance based on this information;

[0107] Medical staff can promptly discover abnormalities in the mother's body by observing the changing trends of these data. For example, if the mother's heart rate suddenly rises and does not drop, medical staff can immediately take appropriate measures, such as checking whether the mother has increased pain, excessive psychological pressure, etc., and take appropriate measures. At the same time, the mother herself can also understand her own physical condition by checking these data and enhance her self-care awareness;

[0108] These data are crucial for assessing the health of the fetus. By observing changes in the fetal heart rate, medical staff can promptly detect whether the fetus is suffering from hypoxia, distress, etc.; through data such as the fetal biparietal diameter and femur length, they can understand whether the fetus is growing and developing normally; and through data such as the amniotic fluid volume and umbilical cord blood flow, they can determine whether the placenta is functioning normally. Based on these data, medical staff can promptly adjust the midwifery plan and take appropriate measures to ensure the health of the fetus;

[0109] Medical staff and mothers can take timely actions based on these prompts and suggestions. For example, when the system prompts mothers to adjust the direction of force, they can follow the prompts to improve the efficiency of delivery; when the system recommends oxygen therapy for the fetus, medical staff can provide oxygen therapy for mothers in time and operate it to ensure the health of the fetus.

[0110] Working principle and use process of the present invention: Assessment of maternal physical condition and adjustment of midwifery strategy:

[0111] Physical condition assessment: A combination of three-dimensional ultrasound and physical examination is used to conduct a comprehensive assessment of the mother's pelvic shape, fetal size, fetal position and other factors.

[0112] Three-dimensional ultrasound is used to accurately measure the various diameters of the pelvis, including the anteroposterior diameter and transverse diameter of the pelvic inlet, the anteroposterior diameter and transverse diameter of the mid-pelvis, and the anteroposterior diameter and transverse diameter of the pelvic outlet, to determine whether the pelvis is suitable for normal delivery and to estimate the difficulties that may be encountered during delivery.

[0113] Determine the position and posture of the fetus in the uterus.

[0114] Real-time monitoring of the mother's physiological indicators and psychological state.

[0115] Physiological indicators monitored include heart rate (normal range 60-100 beats / minute, collected by heart rate monitor), blood pressure (systolic pressure 90-140 mmHg, diastolic pressure 60-90 mmHg, measured by electronic sphygmomanometer), respiratory rate (normal adult 12-20 times / minute, collected by respiratory sensor), body temperature (normal range 36-37.2℃, measured by thermometer) and blood oxygen saturation (should be maintained at 95%-100%, collected by oximeter).

[0116] The psychological state is assessed by psychological scales, and the psychological stress level of the mother is regularly understood.

[0117] Adjustment of midwifery strategy: Adjustment based on physical condition assessment and monitoring results.

[0118] If the mother is under too much psychological pressure, such as anxiety that significantly affects her cooperation, psychological counseling measures should be taken.

[0119] Implement music therapy and play soothing music for the mother to stimulate the nervous system, regulate the endocrine system, reduce the level of stress hormones (such as adrenaline and cortisol, etc.), and make the mother feel relaxed and calm.

[0120] Conduct breathing relaxation training to guide mothers to use correct breathing methods (such as deep breathing and abdominal breathing) to increase oxygen supply, reduce muscle tension, relieve pain, and at the same time help mothers divert their attention and improve psychological and physiological tolerance.

[0121] Labor force monitoring and guidance:

[0122] Force data collection: Based on the principles of biomechanics, sensors (such as pressure sensors, electromyography sensors, etc.) are used to collect real-time force data during the delivery process of the mother, including force direction (expressed in angle or three-dimensional coordinate direction), force size (in Newtons, pressure is measured and converted by pressure sensors), and force duration (recorded in seconds).

[0123] Force pattern analysis and feedback: Based on the collected data, the force pattern of the parturient is analyzed using the formula F=ma (where F represents force, m represents the mass parameter related to the parturient's force, and a represents acceleration, which is calculated using the data collected by the sensor).

[0124] By processing the data from the pressure sensor and the electromyography sensor, the value of acceleration is calculated, and combined with the pre-set quality parameters related to the force exerted by the parturient, the magnitude and direction of the force are obtained.

[0125] Provide real-time feedback and guidance to mothers and midwives through a visual interface (such as a display screen).

[0126] If the analysis results show that the direction of the mother's force is deviated, the visual interface will promptly send out a prompt signal (such as displaying an arrow indicating the correct direction of force) to guide the mother to adjust the direction of force to improve delivery efficiency and reduce physical exertion of the mother.

[0127] Fetal monitoring and intervention:

[0128] Fetal status monitoring: using a combination of continuous fetal heart rate monitoring technology and fetal ultrasound examination.

[0129] The fetal heart rate (normal range: 110-160 beats / minute) and its variations (including short-term variations of 6-25 beats / minute, and long-term variations analyzed by a specific algorithm) are continuously monitored by a fetal heart monitor to understand the fetal heart function and intrauterine condition in real time.

[0130] Ultrasound examination is used to observe fetal movement, amniotic fluid volume (ultrasound-assessed amniotic fluid index AFI is between 5-25cm or maximum amniotic fluid depth is between 2-8cm), umbilical cord blood flow (the ratio of the peak systolic to end-diastolic flow velocity S / D of the umbilical artery blood flow should be less than 3 in the normal late pregnancy), etc., to comprehensively assess the health of the fetus.

[0131] Abnormal intervention measures: When abnormal conditions are detected in the fetus (such as fetal heart rate deceleration, decreased fetal movement, etc.), the system automatically activates the early warning mechanism and takes different measures according to the preset intervention plan.

[0132] If the fetal heart rate deceleration is mild and of short duration, the system will prompt and guide the mother to change her body position (such as lying on the left side) to improve placental blood circulation and restore the fetus's normal heart rate.

[0133] If the fetal heart rate deceleration is more serious (such as lasting longer and with a larger amplitude), notify the doctor promptly for further examination and treatment.

[0134] Take oxygen inhalation measures to increase the oxygen content in the mother's blood, thereby increasing the oxygen supply to the placenta and improving the fetus's hypoxia.

[0135] Depending on the specific conditions of the mother and fetus, intravenous infusion may be needed to replenish the mother's body with water and nutrients, maintain blood volume and blood pressure stability, improve placental blood circulation, and can also be used as a route of administration for certain drug treatments.

[0136] In emergency situations (such as severe fetal heart rate abnormalities, prolonged fetal heart rate deceleration that cannot be improved by other measures, or other life-threatening conditions for the fetus, such as umbilical cord prolapse, placental abruption, etc.), emergency cesarean section is performed to quickly remove the fetus to avoid serious complications caused by prolonged hypoxia, ensure the safety of the fetus, and at the same time deal with possible life-threatening conditions of the mother.

[0137] Information integration and interaction of midwifery system:

[0138] Data acquisition module:

[0139] Comprehensively collect maternal physiological data, fetal monitoring data, and labor force data to provide a basis for subsequent analysis.

[0140] Data analysis and processing module:

[0141] Clean, analyze and mine the collected data.

[0142] Set the noise threshold to identify and remove noise components in the collected data.

[0143] Determine the relationship between different data parameters by calculating correlation coefficients (such as Pearson correlation coefficient); analyze the changing trends of data over time (such as the changing trends of maternal heart rate, fetal heart rate, maternal force and frequency, etc.); mine frequently occurring patterns in the data (such as maternal force patterns) and identify abnormal patterns (such as abnormal patterns in fetal monitoring data).

[0144] Decision support module:

[0145] Provide personalized midwifery plans and decision-making recommendations to medical staff based on the analysis results.

[0146] Comprehensively consider the results of the maternal physical condition assessment, physiological data monitoring and fetal monitoring data, quantitatively assess the delivery risk (such as setting a delivery risk index), and choose the appropriate delivery method (such as natural delivery, assisted delivery or cesarean section) according to the degree of risk and the specific situation of the mother and fetus.

[0147] The timing of intervention (such as when the fetal heart rate drops abnormally and reaches a certain degree or the maternal blood pressure fluctuates abnormally and lasts for a certain period of time) and the intensity of intervention measures (such as changing body position and oxygen inhalation for mild hypoxia, and intravenous infusion or emergency cesarean section for severe hypoxia) are determined based on fetal monitoring data and the maternal physical condition.

[0148] User interaction module:

[0149] The touch screen design provides a friendly operation interface.

[0150] Set the data update frequency (physiological data is updated every 1-5 minutes, fetal monitoring data is updated every 1-2 minutes, and labor force data is updated in real time) to ensure that medical staff and mothers can obtain the latest information in a timely manner.

[0151] Determine how the data is presented on the interactive interface (such as using charts to show the changing trends of the mother's physiological data, waveform charts to show changes in fetal heart rate, and a combination of numbers and text descriptions to show labor effort data and system prompts and suggestions, etc.) to facilitate users' intuitive understanding.

[0152] Ensure that the interface response time is within 1-2 seconds, simplify the operation steps, and improve the convenience and efficiency of user operation. At the same time, it displays the basic information of the mother, physiological index monitoring data, fetal monitoring data, and system prompts and suggestions, which is convenient for medical staff to formulate midwifery plans and make clinical decisions, and also convenient for mothers to understand their own and fetal conditions, and take timely actions according to prompts and suggestions.
