Description

Technical Field

[0001] This invention relates to the field of health assessment technology, and more specifically, to a knowledge graph-driven health assessment and training simulation system in a postpartum meta-environment. Background Technology

[0002] The Postpartum Meta-Context Knowledge Graph-Driven Health Assessment and Training Simulation System is a comprehensive system that utilizes meta-context technology and knowledge graphs to simulate postpartum health assessment and nursing training. It boasts advantages such as high scene fidelity, strong assessment systematization, and excellent training interactivity, and is widely used in postpartum nursing education and training.

[0003] The accuracy of assessments and the effectiveness of training in postpartum care are crucial factors influencing teaching outcomes. However, traditional postpartum care training often struggles to guarantee the comprehensiveness of health assessments. Insufficiently diverse assessment dimensions lead to biases in judging the mother's physical condition and the newborn's health status, affecting the relevance and applicability of nursing plans. It also fails to address comprehensive assessment issues in complex scenarios, resulting in a disconnect between training and actual needs and reducing its practical value. Furthermore, the lack of dynamic feedback mechanisms during training hinders timely understanding of operational problems, preventing adjustments to training strategies and further impacting the quality and efficiency of the training.

[0004] Therefore, it is necessary to design a knowledge graph-driven health assessment and training simulation system in the postpartum meta-context to solve the problems of lack of comprehensiveness in assessment, disconnect between training and actual needs, and lack of dynamic feedback in traditional postpartum nursing training. Summary of the Invention

[0005] In view of this, the present invention proposes a knowledge graph-driven health assessment and training simulation system in the postpartum meta-context, which aims to solve the problems of lack of comprehensiveness in assessment, disconnect between training and actual needs, and lack of dynamic feedback in traditional postpartum nursing training.

[0006] This invention proposes a knowledge graph-driven health assessment and training simulation system in the postpartum meta-context, including: a milk generation module for generating simulated milk; The newborn simulation module is used to simulate the crying state of a newborn. When the newborn is crying, the sucking action triggers the milk intake process, and the crying stops after sucking the milk. The milk-to-urine conversion module is used to simulate the metabolic process of milk in a newborn's body. When milk enters the newborn's simulated stomach, it mixes the simulated milk with simulated digestive juices to generate simulated urine, which is then transported through a pipe to the simulated urethra for discharge. The milk-urine conversion module is also used to monitor the cumulative amount of simulated urine in the diaper and to preset a urine volume threshold. When the simulated urine volume is less than or equal to the urine volume threshold, keep the newborn calm. When the simulated urine volume exceeds the urine volume threshold, the newborn simulation module is triggered to enter the second crying state, and the simulated process of newborn diaper changing care, umbilical cord care or bathing care is started. The uterine involution simulation module is used to simulate the postpartum uterine involution process. When the newborn simulation module performs a sucking action, it triggers the uterine contraction simulation mechanism. Part of the simulated urine is injected into the simulated uterine cavity through the channel. The uterine cavity is equipped with an inverted container filled with red liquid. When the simulated urine flows in, the red liquid channel is opened, so that the red liquid mixes with the simulated urine to form simulated lochia and flows out of the body. The central control module is electrically connected to each module and is used to receive status signals from each module and send control commands to each module according to the preset newborn care process logic. The central control module is also used to monitor the operation status of each module in real time during the training process. When the operation does not meet the preset standards, it sends prompt information and guides the correct operation process.

[0007] Furthermore, it also includes: a breast simulation module, which is equipped with simulated mammary ducts and milk troughs, the breast simulation module being used for breast unblocking training, and releasing a portion of simulated milk after unblocking is completed; The breast simulation module is also used to simulate pathological conditions, including nipple retraction and nipple fissures, for corresponding nipple care training.

[0008] Furthermore, it also includes: a system repair module, used to clean and maintain the pipes of each module, the system repair module being electrically connected to the central control module, and initiating the cleaning process after receiving a pipe cleaning command; The cleaning process includes: first, flushing all pipes of the milk production module, milk-urine conversion module, uterine involution simulation module and breast simulation module with a clean water delivery device for a preset flushing time; When the rinsing time reaches the preset rinsing time, the central control module sends a command to start the gas drying device, which uses high-pressure gas to dry the inside of the pipeline for the preset drying time. The system repair module is also used to monitor the cleanliness status of the pipeline and preset a cleanliness threshold. When the cleanliness of the pipeline is detected to be greater than or equal to the cleanliness threshold, the cleaning is determined to be completed and feedback is sent to the central control module. When the cleanliness is less than the cleanliness threshold, the clean water flushing process is restarted.

[0009] Furthermore, the breast module, during the unblocking training, includes: The breast simulation module is equipped with several simulated mammary ducts and milk pools, and a pressure sensor is also installed inside the breast simulation module. A first preset intensity and a second preset intensity are preset, with the first preset intensity being less than the second preset intensity; When the force of the unblocking operation is within the range of the first and second preset forces, the mammary ducts gradually open, the milk ducts release simulated milk, and the flow rate increases with the increase of force. When the force applied during the unblocking operation is less than the first preset force, it is determined that the unblocking force is insufficient, and feedback is given to increase the first force value. When the force applied during the unblocking operation exceeds the second preset force, it is determined that the unblocking force is too large, and feedback is given to reduce the first force value. A preset flow threshold is set, and when all of the mammary ducts are open and the amount of milk flowing out is greater than or equal to the preset flow, the unblocking is deemed successful. When all of the aforementioned mammary ducts are open but the milk flow is less than the preset flow rate, the flow rate is deemed unqualified. In this case: A first flow rate difference and a second flow rate difference are preset, and the first flow rate difference is less than the second flow rate difference; Calculate the difference between the actual flow rate and the preset flow rate; When the difference is less than or equal to the first flow difference, it indicates that the mammary duct is partially blocked, and the current force should be maintained to continue clearing for 3 seconds. When the difference is greater than the first flow difference and less than or equal to the second flow difference, it indicates that the mammary duct is moderately blocked. It is necessary to increase the second force value within the range of the first and second preset forces to clear the blockage for 5 seconds. When the difference is greater than the second flow difference, it indicates that the mammary ducts are severely blocked, and the entire process of unblocking must be repeated.

[0010] Furthermore, the nipple care training of the breast module includes: simulation of nipple inversion and simulation of nipple fissures; When simulating nipple retraction, a first retraction depth and a second retraction depth are preset, and the first retraction depth is less than the second retraction depth. When simulating a mild indentation, the depth is the first indentation depth. If the depth after the nursing operation is less than or equal to half of the first indentation depth, it is considered qualified. When simulating severe indentation, the depth is the second indentation depth. If the depth after nursing operation is less than or equal to half of the second indentation depth, it is considered qualified. When simulating nipple fissures, a first number of fissures and a second number of fissures are preset, with the first number of fissures being less than the second number of fissures; When simulating mild cracking, the number of cracks is the first crack count. After treatment, the number of cracks equals 0, which is considered acceptable. When simulating severe cracking, the number of cracks is the second number of cracks. If the number of cracks after treatment is less than or equal to half of the second number of cracks, it is considered qualified.

[0011] Furthermore, the water rinsing process of the system repair module includes: A first preset total pipe length and a second preset total pipe length are preset, wherein the first preset total pipe length is less than the second preset total pipe length; A first preset rinsing time, a second preset rinsing time, and a third preset rinsing time are preset, wherein the first preset rinsing time is less than the second preset rinsing time and the third preset rinsing time is less than the third preset rinsing time; When the total length of the system pipeline is less than or equal to the first preset total pipeline length, the first preset flushing time is selected; When the total length of the system pipeline is greater than the first preset total pipeline length and less than or equal to the second preset total pipeline length, the second preset flushing time shall be selected. When the total length of the system pipeline is greater than the second preset total pipeline length, the third preset flushing time is selected. During the flushing process, the turbidity of the pipeline is monitored in real time, and a preset standard turbidity is used. When the turbidity of the pipeline is less than or equal to the standard turbidity, the flushing is terminated in advance.

[0012] Furthermore, the gas drying process of the system repair module includes: The preset pipe diameter, the first preset drying time, and the second preset drying time are preset, and the first preset drying time is less than the second preset drying time. When the average diameter of the pipe is less than or equal to the preset pipe diameter, the first preset drying time is selected; When the average diameter of the pipe is greater than the preset pipe diameter, select the second preset drying time; After drying is completed, the humidity of the pipeline is checked and a preset standard humidity is set. When the humidity of the pipeline exceeds the standard humidity, the drying process is restarted.

[0013] Furthermore, the urine monitoring of the milk-to-urine conversion module includes: A first urine volume threshold and a second urine volume threshold are preset, and the first urine volume threshold is less than the second urine volume threshold; The newborn should remain calm when the amount of urine in the diaper is between 0 and the first urine volume threshold. When the amount of urine in the diaper falls within the range of the first urine volume threshold to the second urine volume threshold, the first crying warning is triggered; When the amount of urine in the diaper exceeds the second urine volume threshold, a second crying is triggered, forcibly initiating diaper changing care; If umbilical cord care or bathing procedures were not performed after changing diapers, urine output should be monitored again after 10 minutes.

[0014] Furthermore, the lochia control of the uterine involution care module includes: A manual switch is installed in the passage between the newborn's urine and the uterus, which can be closed as needed for teaching purposes; Pre-set the first, second, and third postpartum time nodes; The lochia is bright red at the first time point, light red at the second time point, and light yellow at the third time point; When the amount of lochia discharged exceeds the preset total amount, the red liquid bottle inside the uterus stops flowing out. If the vulvar care procedure is performed in accordance with the standards and the amount of lochia discharge is less than or equal to the preset total amount, the care is deemed satisfactory.

[0015] Furthermore, the central control module also performs psychological care assessment and uterine contraction assessment, including: When conducting psychological nursing assessments, a threshold for the newborn's sucking time is preset. When the actual sucking time is greater than or equal to the sucking time threshold, the effectiveness of the mother-child emotional promotion is recorded. When the actual sucking time is less than the sucking time threshold, it indicates that the sucking time needs to be extended to enhance the mother-child bond; When assessing uterine contraction, a preset threshold for the number of sucking times is set. When the number of sucking times is greater than or equal to the threshold, the central control module determines that the effect of promoting uterine contraction is significant. When the number of suctioning sessions is less than the threshold, the central control module prompts that increasing the number of suctioning sessions can accelerate the discharge of lochia. All evaluation results generate training reports in real time, and mark the operation items that did not meet the standards.

[0016] Furthermore, the system also includes a postpartum psychological care module, which is used to pay attention to the psychological changes of postpartum women during postpartum care, and to provide postpartum psychological care through care, sympathy, understanding and encouragement, so as to reduce the occurrence of postpartum depression.

[0017] Furthermore, the postpartum psychological care module includes the following aspects when conducting psychological state assessment and intervention: The postpartum psychological care module has a built-in simulated dialogue library and psychological state assessment scale. By simulating the dialogue interaction between the mother and the caregiver, it extracts emotional keywords in the dialogue and assesses the psychological state in combination with the assessment scale score. Pre-set thresholds for normal emotion, mild emotion, moderate emotion, and high emotion, with the normal emotion threshold lower than the mild emotion threshold, the mild emotion threshold lower than the moderate emotion threshold, and the moderate emotion threshold lower than the high emotion threshold. The psychological state level is determined based on the relationship between the assessment score and each threshold: When the assessment score is less than or equal to the mild emotional threshold, it is determined that the psychological state is good, and the module triggers a positive incentive dialogue. When the assessment score is greater than the mild emotional threshold and less than or equal to the moderate emotional threshold, it is judged as mild emotional fluctuation. The module initiates a guided care process, which combines simulated listening feedback with relaxation training guidance. When the assessment score is greater than the moderate emotion threshold and less than or equal to the high emotion threshold, it is judged as a moderate anxiety tendency. The module calls the professional psychological counseling simulation module to generate a targeted intervention plan, which includes cognitive restructuring guidance and family support simulation scenarios. When the assessment score exceeds the high emotional threshold, it is judged as a high-risk depressive tendency. The module links with the central control module to trigger a multi-dimensional intervention mechanism: simultaneously pushes a psychological crisis warning to the training guidance terminal, generates a comprehensive intervention report including family support, social support, and professional medical intervention suggestions, and starts a simulated group psychological counseling scenario. Thirty minutes after the intervention, the module re-obtained scores through dialogue interaction and scale assessment. If the retest score was less than or equal to the moderate emotion threshold, the intervention was deemed effective. If the retest score was greater than the moderate emotion threshold, the intervention process for the corresponding level was repeated until the retest score did not exceed the moderate emotion threshold.

[0018] Furthermore, the system also includes a uterine and pelvic floor muscle involution simulation module, which is used to simulate the postpartum pelvic floor muscle involution process. When lochia is discharged, it guides the mother to do basic postpartum pelvic floor muscle involution training, mainly including Kegel exercises and abdominal breathing exercises. Compared with existing technologies, the beneficial effects of this invention are as follows: This system, through the coordinated operation of its various modules, can accurately simulate a series of postpartum maternal and infant physiological and nursing scenarios, including newborns suckling milk, metabolizing it into urine, crying due to excessive urine triggering nursing care, and postpartum uterine involution producing lochia. It has advantages such as realistic simulation scenarios, strong process linkage, and timely operational feedback, effectively improving the scientific rigor, feasibility, professionalism, and interdisciplinary relevance of knowledge and skills in comprehensive postpartum nursing training, showcasing the authenticity and extended connections of clinical cases. During training, the central control module's real-time monitoring and standardized guidance of operations help trainees quickly master key skills such as breast care, newborn feeding, newborn umbilical cord care, diaper changing, uterine involution care, and extended postpartum rehabilitation care. This solves the problems of single scenarios and difficulty in controlling operational standards in traditional training, significantly improving the interdisciplinary and comprehensive effects of training skills and the quality of nursing skills training, achieving a deep integration of immersive learning, high-quality teaching management, comprehensive nursing skills, and health assessment for students.

[0021] Reference Figure 1 As shown in some embodiments of this application, a knowledge graph-driven health assessment and training simulation system in a postpartum meta-environment includes: a milk production module, a newborn simulation module, a milk-urine conversion module, a uterine involution simulation module, and a central control module. Specifically, the milk generation module is used to generate simulated milk; The newborn simulation module is used to simulate the crying state of a newborn. When the newborn is crying, the sucking action triggers the milk intake process, and the crying stops after sucking the milk. The milk-to-urine conversion module is used to simulate the metabolic process of milk in a newborn's body. When milk enters the newborn's simulated stomach, it mixes the simulated milk with simulated digestive juices to generate simulated urine, which is then transported through a pipe to the simulated urethra for discharge. The milk-to-urine conversion module is also used to monitor the amount of simulated urine accumulated in the diaper and to preset a urine volume threshold.

When the simulated urine volume exceeds the urine volume threshold, the newborn simulation module is triggered to enter the second crying state, and the simulated process of newborn diaper changing care, umbilical cord care or bathing care is started. The uterine involution simulation module is used to simulate the postpartum uterine involution process. When the newborn simulation module performs a sucking action, it triggers the uterine contraction simulation mechanism. Some simulated urine is injected into the simulated uterine cavity through the channel. The uterine cavity is equipped with an inverted container filled with red liquid. When the simulated urine flows in, the red liquid channel is opened, allowing the red liquid to mix with the simulated urine to form simulated lochia and flow out of the body. The postpartum psychological care module is used to focus on the psychological changes of postpartum women during the postpartum period. It provides postpartum psychological care through care, empathy, understanding, and encouragement to reduce the incidence of postpartum depression.

[0022] The postpartum psychological care module includes psychological status assessment and intervention, including: The postpartum psychological care module has a built-in simulated dialogue library and psychological state assessment scale. It extracts emotional keywords from the dialogue by simulating the dialogue between the mother and the caregiver, and assesses the psychological state by combining the scores of the assessment scale. Pre-set thresholds for mild, moderate, and high emotions, with the mild emotion threshold lower than the moderate emotion threshold, and the moderate emotion threshold lower than the high emotion threshold. The psychological state level is determined based on the relationship between the assessment score and each threshold: When the assessment score is less than or equal to the mild emotional threshold, it is determined that the psychological state is good, and the module triggers a positive incentive dialogue. When the assessment score is greater than the mild emotional threshold and less than or equal to the moderate emotional threshold, it is judged as mild emotional fluctuation. The module initiates a guided care process, which combines simulated listening feedback with relaxation training guidance. When the assessment score is greater than the moderate emotion threshold and less than or equal to the high emotion threshold, it is judged as a moderate anxiety tendency. The module calls the professional psychological counseling simulation module to generate a targeted intervention plan, which includes cognitive restructuring guidance and family support simulation scenarios. When the assessment score exceeds the high emotional threshold, it is judged as a high-risk depressive tendency. The module links with the central control module to trigger a multi-dimensional intervention mechanism: simultaneously pushes a psychological crisis warning to the training guidance terminal, generates a comprehensive intervention report including family support and professional medical intervention suggestions, and starts a simulated group psychological counseling scenario. Thirty minutes after the intervention, the module re-obtained scores through dialogue interaction and scale assessment. If the retest score was less than or equal to the moderate emotion threshold, the intervention was deemed effective. If the retest score was greater than the moderate emotion threshold, the intervention process for the corresponding level was repeated until the retest score did not exceed the moderate emotion threshold.

[0023] The uterine and pelvic floor muscle recovery simulation module is used to simulate the postpartum pelvic floor muscle recovery process. When lochia is flowing, it guides postpartum women to do basic pelvic floor muscle recovery training, mainly including Kegel exercises and abdominal breathing exercises. The central control module is electrically connected to each module and is used to receive status signals from each module and send control commands to each module according to the preset newborn care process logic. The central control module is also used to monitor the operation status of each module in real time during the training process. When the operation does not meet the preset standards, it sends prompt information and guides the correct operation process.

[0024] The above embodiments, through the coordinated operation of various modules, can accurately simulate a series of postpartum maternal and infant physiological and nursing scenarios, including newborns suckling milk, metabolizing it into urine, crying due to excessive urine triggering nursing care, and postpartum uterine involution producing lochia. It has advantages such as realistic simulation scenarios, strong process linkage, and timely operational feedback, effectively improving the authenticity and professionalism of postpartum nursing training. During training, the central control module's real-time monitoring and standardized guidance of operations help trainees quickly master key skills such as newborn feeding, diaper changing, and uterine involution care, solving the problems of monotonous scenarios and difficulty in controlling operational standards in traditional training, significantly improving training effectiveness and the quality of nursing skills development.

[0025] Reference Figure 2 As shown, it also includes: a breast simulation module, which is equipped with simulated mammary ducts and milk cistern structures. The breast simulation module is used for breast unblocking training and releases some simulated milk after unblocking is completed. The breast simulation module is also used to simulate pathological conditions, including poor milk flow, inverted nipples, and cracked nipples, to conduct corresponding nipple care training. This can be extended to the prevention, care, and health assessment of mastitis.

[0026] Specifically, the breast module, during the dredging training, includes: The breast simulation module is equipped with several simulated mammary ducts and milk cisterns, and also contains pressure sensors. A first preset intensity and a second preset intensity are preset, with the first preset intensity being less than the second preset intensity; When the force of the unblocking operation is within the range of the first and second preset forces, the mammary ducts gradually open, the milk ducts release simulated milk, and the flow rate increases with the increase of force. When the force applied during the unblocking operation is less than the first preset force, it is determined that the unblocking force is insufficient, and feedback is given to increase the first force value. When the force applied during the unblocking operation exceeds the second preset force, it is determined that the unblocking force is too large, and feedback is given to reduce the first force value. A preset flow threshold is set. When all the mammary ducts are open and the milk flow is greater than or equal to the preset flow, the unblocking is deemed successful. When all mammary ducts are open but the milk flow is less than the preset flow rate, the flow rate is deemed unqualified. In this case: A first flow rate difference and a second flow rate difference are preset, and the first flow rate difference is less than the second flow rate difference; Calculate the difference between the actual flow rate and the preset flow rate; When the difference is less than or equal to the first flow difference, it indicates that the mammary duct is partially blocked, and the current force should be maintained to continue clearing for 3 seconds. When the difference is greater than the first flow difference and less than or equal to the second flow difference, it indicates that the mammary duct is moderately blocked. It is necessary to increase the second force value within the range of the first and second preset forces to clear the blockage for 5 seconds. When the difference is greater than the second flow difference, it indicates that the mammary ducts are severely blocked, and the entire process of unblocking must be repeated.

[0027] Specifically, the nipple care training in the breast module includes: simulation of nipple inversion and simulation of nipple fissures; When simulating nipple retraction, a first retraction depth and a second retraction depth are preset, and the first retraction depth is less than the second retraction depth. When simulating a mild indentation, the depth is the first indentation depth. If the depth after the nursing operation is less than or equal to half of the first indentation depth, it is considered qualified. When simulating severe indentation, the depth is the second indentation depth. If the depth after nursing operation is less than or equal to half of the second indentation depth, it is considered qualified. When simulating nipple fissures, a first number of fissures and a second number of fissures are preset, with the first number of fissures being less than the second number of fissures; When simulating mild cracking, the number of cracks is the first crack count. After treatment, the number of cracks equals 0, which is considered acceptable. When simulating severe cracking, the number of cracks is the second number of cracks. If the number of cracks after treatment is less than or equal to half of the second number of cracks, it is considered qualified.

[0028] Specifically, during the breast module's unblocking training, there are 15 simulated mammary ducts and milk troughs, with built-in pressure sensors and two preset force thresholds of 1N and 3N. Within this range, the mammary ducts gradually open, and the milk flow increases with the increase of force. At the same time, there are preset flow thresholds of 5ml / min and flow difference standards of 1ml / min and 3ml / min, which are used to determine whether the unblocking is qualified and the degree of blockage.

[0029] Specifically, in the nipple care training, the simulated nipple inversion has two depths: 2mm (mild) and 5mm (severe). After care, the inversion depth must be less than or equal to 1mm and 2.5mm respectively to pass. The simulated nipple fissure has two crack counts: 2 (mild) and 5 (severe). After care, the crack count must be 0 and less than or equal to 2 respectively to pass. The operation of each module is monitored and regulated by the central control module.

[0030] Understandably, the breast simulation module, by setting up 15 simulated mammary ducts and milk troughs, combined with pressure sensors and preset parameters such as force and flow, can accurately simulate breast unblocking operations, providing real-time feedback on whether the force is appropriate and the degree of blockage, helping trainees master correct unblocking techniques. It also simulates pathological conditions such as nipple retraction and fissures, setting clear qualification standards, which can effectively conduct targeted nursing training and improve trainees' ability to deal with breast-related problems. Simultaneously, this module works in conjunction with the central control module and system repair module to ensure standardized and orderly training, significantly improving the professionalism and effectiveness of postpartum breast care training.

[0031] Reference Figure 2 As shown, it also includes: a system repair module, which is used to clean and maintain the pipes of each module. The system repair module is electrically connected to the central control module and starts the cleaning process after receiving the pipe cleaning command. The cleaning process includes: first, flushing all pipes of the milk production module, milk-urine conversion module, uterine involution simulation module, and breast simulation module with a clean water delivery device, with a preset flushing time; When the rinsing time reaches the preset rinsing time, the central control module sends a command to start the gas drying device, which uses high-pressure gas to dry the inside of the pipeline for the preset drying time. The system repair module is also used to monitor the cleanliness status of the pipeline and preset a cleanliness threshold. When the cleanliness of the pipeline is detected to be greater than or equal to the cleanliness threshold, the cleaning is determined to be completed and feedback is sent to the central control module. When the cleanliness is less than the cleanliness threshold, the clean water flushing process is restarted.

[0032] Specifically, the water rinsing process for the system repair module includes: A first preset total pipe length and a second preset total pipe length are preset, wherein the first preset total pipe length is less than the second preset total pipe length; A first preset rinsing time, a second preset rinsing time, and a third preset rinsing time are preset, wherein the first preset rinsing time is less than the second preset rinsing time and the third preset rinsing time is less than the third preset rinsing time; When the total length of the system pipeline is less than or equal to the first preset total pipeline length, the first preset flushing time is selected; When the total length of the system pipeline is greater than the first preset total pipeline length and less than or equal to the second preset total pipeline length, the second preset flushing time shall be selected. When the total length of the system pipeline is greater than the second preset total pipeline length, the third preset flushing time is selected. During the flushing process, the turbidity of the pipeline is monitored in real time, and a preset standard turbidity is used. When the turbidity of the pipeline is less than or equal to the standard turbidity, the flushing is terminated in advance.

[0033] Specifically, the gas drying process of the system repair module includes: The preset pipe diameter, the first preset drying time, and the second preset drying time are preset, and the first preset drying time is less than the second preset drying time. When the average diameter of the pipe is less than or equal to the preset pipe diameter, the first preset drying time is selected; When the average diameter of the pipe is greater than the preset pipe diameter, select the second preset drying time; After drying is completed, the humidity of the pipeline is checked and a preset standard humidity is set. When the humidity of the pipeline exceeds the standard humidity, the drying process is restarted.

[0034] Specifically, the clean water rinsing process is preset with different total pipe lengths and corresponding rinsing times: 30 seconds for a total length ≤10m, 60 seconds for 10-20m, and 90 seconds for >20m. Turbidity is monitored during rinsing, and the process ends early if the standard is met.

[0035] Specifically, the gas drying process is preset to a pipe diameter of 5mm. For pipes with an average diameter ≤5mm, the drying time is 20 seconds, and for pipes with an average diameter >5mm, the drying time is 40 seconds. After the process is completed, the humidity is checked. If the humidity exceeds the standard, the process is repeated to ensure that the pipes are clean and maintained in accordance with regulations.

[0036] Understandably, the system repair module, in collaboration with the central control module, performs water flushing and gas drying on the pipelines of each module according to a preset procedure, which can effectively clean and maintain the pipelines and ensure their smooth flow. It sets different flushing and drying times according to the total length and diameter of the pipelines, and flexibly adjusts the process in combination with turbidity and humidity monitoring to ensure the cleaning effect. At the same time, it ensures that the pipelines are clean enough by monitoring the cleanliness threshold, which supports the stable operation of each module of the system and improves the reliability and continuity of the training simulation.

[0037] Specifically, urine monitoring in the milk-to-urine conversion module includes: A first urine volume threshold and a second urine volume threshold are preset, and the first urine volume threshold is less than the second urine volume threshold; The newborn should remain calm when the amount of urine in the diaper is between 0 and the first urine volume threshold. When the amount of urine in the diaper falls within the range of the first urine volume threshold to the second urine volume threshold, the first crying warning is triggered; When the amount of urine in the diaper exceeds the second urine volume threshold, a second crying is triggered, forcibly initiating diaper changing care; If umbilical cord care or bathing procedures were not performed after changing diapers, urine output should be monitored again after 10 minutes.

[0038] Specifically, the milk-to-urine conversion module has a preset first urine volume threshold of 5ml and a second urine volume threshold of 10ml. When the urine volume is 0 to 5ml, the newborn is quiet. When the urine volume is 5 to 10ml, the first crying warning is triggered. When the urine volume is greater than 10ml, the second crying is triggered and diaper changing care is forcibly started. If umbilical cord or bath care is not performed after diaper changing, the urine volume is re-monitored after 10 minutes.

[0039] Understandably, the milk-to-urine conversion module, by presetting a first and a second urine volume threshold, triggers different states for newborns, such as quietness, crying, and forced diaper changing, and re-monitors urine volume after diaper changing. It can accurately simulate the different reactions and corresponding care needs of newborns caused by changes in urine volume, enabling trainees to clearly grasp the timing and procedures of urine volume-related care, improving the authenticity and standardization of newborn care training, and helping trainees to efficiently master relevant skills.

[0040] Specifically, the lochia control component of the uterine involution care module includes: A manual switch is installed in the passage between the newborn's urine and the uterus, which can be closed as needed for teaching purposes; Pre-set the first, second, and third postpartum time nodes; The lochia is bright red at the first time point, light red at the second time point, and light yellow at the third time point; When the amount of lochia discharged exceeds the preset total amount, the red liquid bottle inside the uterus stops flowing out. If the vulvar care procedure is performed in accordance with the standards and the amount of lochia discharge is less than or equal to the preset total amount, the care is deemed satisfactory.

[0041] Specifically, in the lochia control section of the uterine involution nursing module, a manual switch is provided between the newborn's urine and the uterus, which can be closed as needed for teaching. The preset first postpartum time point is within 24 hours (bright red lochia indicates bloody lochia), the second time point is 2-10 days (pale red lochia indicates serous lochia), and the third time point is after 10 days (pale yellow lochia indicates white lochia). The preset total lochia volume is 50ml. When the outflow exceeds 50ml, the red liquid bottle in the uterus stops flowing. If the vulvar care operation is standardized and the outflow is ≤50ml, the care is considered qualified. This setting is linked with the central control module to ensure the authenticity and standardization of lochia changes and nursing training.

[0042] Understandably, the lochia control function of the uterine involution nursing module can meet different teaching needs by setting a manual switch. It displays changes in lochia color according to preset time nodes. Combined with the outflow threshold control and nursing qualification judgment standards, it can realistically simulate postpartum lochia changes and nursing scenarios, helping trainees master the key points of lochia observation and vulvar care, improve their practical ability to care for the uterine involution process, and ensure that the training is standardized and effective in conjunction with the central control module.

[0043] Specifically, the central control module also performs psychological care assessments and uterine contraction assessments, including: When conducting psychological nursing assessments, a threshold for the newborn's sucking time is preset. When the actual sucking time is greater than or equal to the sucking time threshold, the effectiveness of the mother-child emotional promotion is recorded. When the actual sucking time is less than the sucking time threshold, it indicates that the sucking time needs to be extended to enhance the mother-child bond; When assessing uterine contraction, a preset threshold for the number of sucking times is set. When the number of sucking times is greater than or equal to the threshold, the central control module determines that the effect of promoting uterine contraction is significant. When the number of suctioning sessions is less than the threshold, the central control module prompts that increasing the number of suctioning sessions can accelerate the discharge of lochia. All evaluation results generate training reports in real time, and mark the operation items that did not meet the standards.

[0044] Specifically, in the psychological nursing assessment, the central control module presets a threshold of 10 minutes for newborn sucking time. If the actual sucking time is ≥10 minutes, it is recorded as effective in promoting mother-child emotional bonding; if it is <10 minutes, it is suggested that the sucking time should be extended. In the uterine contraction assessment, the preset threshold for the number of suckings is 8 times. If the number of suckings is ≥8 times, it is determined that the effect of promoting uterine contraction is significant; if it is <8 times, it is suggested that increasing the number of suckings can accelerate the discharge of lochia. All assessment results generate training reports in real time and mark the operation items that have not met the standards. The module works in conjunction with other modules to ensure the standardization of postpartum psychological and uterine contraction nursing assessments.

[0045] Understandably, the central control module assesses psychological care and uterine contraction by setting preset thresholds for sucking duration and number of suckings. When the actual sucking duration is greater than or equal to the threshold, it records that the promotion of maternal and infant emotional bond is effective; otherwise, it prompts to extend the time. When the number of suckings is greater than or equal to the threshold, it determines that the uterine contraction effect is significant; otherwise, it prompts to increase the number of suckings. It also generates a training report in real time, including items that did not meet the standards, which can accurately reflect the effect of relevant care during training, guide trainees to optimize their operations, and effectively improve the pertinence and effectiveness of postpartum psychological care and uterine contraction care training.
