Description

Technical Field

[0001] The present application relates to the field of smart medical technology, and in particular to a method and system for evaluating neurogenic intestinal dysfunction. Background Art

[0002] Neurogenic bowel dysfunction (NBD) refers to sensory and motor disorders, colon activity and anorectal dysfunction caused by the loss of central nervous system innervation in the intestine, which manifests as intestinal complications such as constipation, diarrhea, abdominal distension, fecal incontinence, etc., which seriously affect the quality of life and the prognosis of the primary disease. In addition, neurogenic bowel dysfunction lasts for a long time, is difficult to self-manage, and is prone to cause anxiety, which reduces the quality of life.

[0003] There are few applications in the nursing of neurogenic intestinal dysfunction after stroke. The clinical management or intervention measures for neurogenic intestinal dysfunction are mainly nursing experience for disease symptom management. There is a lack of corresponding standardized and integrated management measures through the classification and stage of neurogenic intestinal dysfunction. And according to a large number of literature reports, the research population is mostly concentrated in patients with spinal cord injury, and less attention is paid to the stroke population. However, the pain and distress caused by neurogenic intestinal dysfunction to stroke patients are very common in clinical practice. Therefore, it is crucial to provide standardized and effective intestinal management for patients with neurogenic intestinal dysfunction after stroke. There is evidence that intestinal management can avoid re-admission in the post-acute rehabilitation period.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] This example uses intestinal management in patients with neurogenic intestinal dysfunction after hemorrhagic stroke, in order to obtain a more comprehensive evaluation method and management process for neurogenic intestinal dysfunction, and improve the intestinal function of patients with neurogenic intestinal dysfunction after hemorrhagic stroke. In this way, an effective intestinal management method is explored to alleviate the impact of neurogenic intestinal dysfunction on patients with hemorrhagic stroke, and to provide a basis for self-management of patients with neurogenic intestinal dysfunction after hemorrhagic stroke after discharge.

[0021] See also Figure 1 , which shows a structural diagram of a neurogenic intestinal dysfunction assessment system provided by an embodiment of the present invention, including an information acquisition unit S101, a time series change processing unit S102, a space processing unit S103 and a state information feature feedback unit S104.

[0022] The information collection unit S101 is used to collect life fragments output by the patient to be evaluated in a preset period during daily activities, cluster and divide the life fragments based on the life fragment scenarios, obtain life fragment application scenarios, and randomly select one of the life fragment application scenarios as a candidate scenario.

[0023] With the development of neurogenic intestinal dysfunction assessment technology, the daily life recovery of patients is being intervened by more and more people, and people's requirements for daily life are also increasing. In daily activities, nursing staff can make multiple forms of temporal changes with patients to be evaluated. In order to achieve a higher quality of daily life, nursing staff usually adjust the content of daily life based on the goals of patients to be evaluated, so as to bring better daily life behavior effects, improve the behavioral fluency of patients to be evaluated, and create a better daily activity atmosphere. However, in daily activities, nursing staff can only collect the goals of patients to be evaluated in the form of life fragments. However, due to the large number of life fragments and the extremely fast change speed, it is difficult for nursing staff to distinguish the goals of different patients to be evaluated based on life fragments. Therefore, an information processing method for life fragment information is needed. Considering that only processing motion processing information cannot handle the real obstacle of patients to be evaluated, different sensory state information can be used to comprehensively process the characteristics of life fragments. Through cross-state information processing, the real goals of the current patients to be evaluated can be more accurately collected, and more appropriate life fragment warnings can be given to nursing staff, so as to achieve good temporal changes in daily activities and improve the recovery effect of patients to be evaluated.

[0024] Intestinal management is to promote the recovery of intestinal function and minimize the impact of intestinal dysfunction on patients' daily lives through measures such as diet management, defecation training, abdominal massage, defecation stimulation, increased activities and health education. Based on clinical evidence, a scientific and reasonable nursing plan is formulated; according to the specific development of the patient's condition, nursing intervention is implemented in stages and step by step to obtain patient cooperation, improve nursing compliance, and achieve the purpose of promoting recovery from the disease, while also effectively reducing the occurrence of complications.

[0025] In order to collect life segments that more accurately reflect the goals of the patients to be evaluated, the daily life platform is set to monitor at regular intervals, and the nursing staff is prompted once by processing the life segment target results. First, the life segment information output by the patients to be evaluated in the preset period of daily activities is collected. In the embodiment of the present invention, the preset period is set to 10 minutes, and the specific value can be adjusted by the implementer. However, not all of these collected life segments contain the target meaning.

[0026] Therefore, it is necessary to first cluster the life fragments based on the scenes of the life fragments, and divide the life fragments containing the target information. The life fragment scenes represent the meaning contained in a life fragment. The meaning expressed by each life fragment can be obtained by processing the life fragment scenes. The life fragment application scene is obtained by processing the scene. In the embodiment of the present invention, a neural network model is selected for identification clustering based on the life fragment scenes. All life fragments are clustered according to the type of target to obtain the life fragment application scene. Each life fragment application scene can represent a target. In other embodiments, the clustering can be completed by collecting keywords for the life fragments, and then matching the scene vocabulary. The matched words are used as the target of the application scene. The natural language processing model can also be used for clustering, which is not limited here. It should be noted that the neural network model and the natural language processing model are clustering technologies well known to those skilled in the art, and they will not be elaborated here.

[0027] The results of clustering life fragments into life fragments at least include nutritional status, psychological status, intestinal status and complication scenarios.

[0028] Life fragments are clustered and divided based on separate processing of the text status information of life fragments. Since the application scenarios of life fragments are diverse, in order to facilitate subsequent calculation and processing, a life fragment application scenario is randomly selected as a candidate scenario so that the subsequent processing of only the life fragment application scenario is clearer and more explicit. The processing process based on the candidate scenario can process all life fragment application scenarios.

[0029] The timing change processing unit S102 is used to obtain a monitoring period on a preset period based on the number change trend of all life segments in the life segment application scenario; in the monitoring period, the effective timing duration on the monitoring period is obtained based on the intervention status of all patients to be evaluated and the number of life segment outputs.

[0030] Before processing each type of life fragment application scenario, it is necessary to first process the changes in the number of life fragments of daily activities as a whole, obtain the effective time series duration under the overall processing, and first process the life fragment behavior state information separately. The behavior state refers to the time series change behavior of the patient to be evaluated, such as the life fragment output frequency, time length, POI category and intervention status of the patient to be evaluated. This information does not directly express the intention like text, but provides information such as the interest and participation of the patient to be evaluated. Since the number of life fragments output in daily activities can roughly reflect the attractiveness of daily life content to the patient to be evaluated, when the number of life fragments reaches a peak in a certain period of time, it means that a certain behavior of the nursing staff resonates with the patient to be evaluated, or brings excellent daily life effects, thereby causing more patients to be evaluated to output life fragments for time series changes. At this time, the quality of the life fragments is higher and the confidence weight is higher.

[0031] First, the preset period is divided into two or more monitoring periods, and the period with strong temporal variability is extracted by monitoring the changing trend of the number of life segments during the period. In the embodiment of the present invention, the monitoring period is 2 minutes, that is, the number of all life segments in daily activities is summarized every 2 minutes. The implementation can adjust the selection of the specific monitoring period based on the implementation situation.

[0032] Summarize the sum of the number of life fragments in all life fragment application scenarios in each monitoring cycle, and obtain a set of life fragment numbers based on the corresponding sum of each monitoring cycle. The set of life fragment numbers can reflect the changes in the number of life fragments. In order to further clearly reflect the changing trend of the number of life fragments, preferably, a visualization chart is drawn based on the set of life fragment numbers to obtain a fluctuation visualization chart. The fluctuation visualization chart can intuitively reflect the temporal changes of the daily activities of the patients to be evaluated and the caregivers. The vicinity of the maximum value of the fluctuation visualization chart, that is, the peak position, indicates that the temporal variability of the caregivers and the patients to be evaluated at this moment is relatively strong, while the vicinity of the minimum value, that is, the trough position, indicates that the daily life content at this moment is relatively stable and does not arouse the deterioration of the neurogenic intestinal dysfunction assessment of the patients to be evaluated. It should be noted that the drawing of visualization charts is a technical means well known to those skilled in the art and will not be elaborated here.

[0033] Therefore, the period corresponding to adjacent minimum values ​​can be regarded as a monitoring period, and one monitoring period corresponds to a single peak area. The preset period is divided by the monitoring period, and each monitoring period represents a more efficient time series change between the nursing staff and the patient to be evaluated during this period of time.

[0034] Through different intervention methods in the study group and the control group, the neurogenic intestinal dysfunction scores, nutritional status, psychological status, intestinal conditions and complications of the study group after intervention were better than those of the control group and had clinical significance. In this way, effective intestinal management methods can be explored to reduce the impact of neurogenic intestinal dysfunction on patients with hemorrhagic stroke, and provide a basis for self-management of patients with neurogenic intestinal dysfunction after hemorrhagic stroke after discharge.

[0035] The timing change effect and effective timing duration are different for different monitoring cycles. For monitoring cycles with larger effective timing duration, it means that the target intention of the patient to be evaluated may be more, and the credible change rate of the life fragment information is higher, which can better represent the target of the patient to be evaluated. The present invention collects more new patients to be evaluated for intervention on the premise of retaining the patients to be evaluated who have been intervened by the nursing staff. Therefore, when processing the effective timing duration, considering that the targets of the patients to be evaluated in different intervention states may not be certain, the effective timing duration of the monitoring cycle is obtained based on the intervention state of the patient to be evaluated, which specifically includes: Preferably, in the preset cycle, the patients to be evaluated are divided into intervened patients to be evaluated and non-interventional patients to be evaluated based on the intervention status. The intervened patients to be evaluated are old patients to be evaluated who engage in daily activities, and the non-interventional patients to be evaluated are new patients to be evaluated. By processing the intervention status, the effective time duration obtained can better meet the goals of daily activities, thereby increasing the recovery effect of the patients to be evaluated. In other embodiments, the intervention status of the patients to be evaluated can also be divided into ordinary intervention, special intervention, and non-intervention, etc., which are not limited here.

[0036] The number of cycles in which the output behavior of each patient to be evaluated appears in each monitoring cycle is summarized, and the number of cycles reflects the patient's desire for continuous neurogenic intestinal dysfunction evaluation. The larger the number of cycles, the better the effective time series duration of the patient to be evaluated. For example, in a total of 10 monitoring cycles, one patient to be evaluated has output life fragment behaviors in 3 of the monitoring cycles, with a cycle number of 3, and another patient to be evaluated has output life fragment behaviors in 7 of the monitoring cycles, with a cycle number of 7. It can be seen that the patient to be evaluated with a cycle number of 7 has a better effective time series duration and a greater willingness for time series change. The quotient of the number of cycles and the total number of monitoring cycles is further used as the time series change quotient. The time series change quotient is an influence coefficient based on the desire for continuous neurogenic intestinal dysfunction evaluation of each user. When the patient's willingness for time series change is higher, the greater its influence on the effective time series duration is considered. Since the continuous neurogenic intestinal dysfunction evaluation of some invalid life fragments is poor, the time series change quotient also reduces the influence of invalid life fragments at a certain rate of change.

[0037] The standardized value of the number of life segments output by each patient to be evaluated in each monitoring cycle is multiplied by the time series change quotient value to obtain the effective time series duration of each patient to be evaluated in each monitoring cycle. The effective time series duration is reflected by the number of life segments output by each patient to be evaluated, and is adjusted by the time series change quotient value to obtain the effective time series duration of each patient to be evaluated in each monitoring cycle. The effective time series duration of the patient to be evaluated reflects the time series change of each patient to be evaluated in each monitoring cycle.

[0038] In each monitoring cycle, the weighted sum of the effective time series durations of all patients to be evaluated who have not been evaluated and the effective time series durations of all patients to be evaluated who have been evaluated is used to obtain the effective time series duration of each monitoring cycle. The effective time series duration in the monitoring cycle reflects the different effective time series durations of each monitoring cycle. The larger the effective time series duration, the higher the willingness for temporal changes in the life segments in the corresponding monitoring cycle, and the stronger the confidence weight of the life segments expressing the target.

[0039] It should be noted that, since the purpose of considering the patients to be evaluated in daily activities is to expect more patients to be evaluated to intervene in daily activities, a larger weight is given to the effective time series duration of the patients to be evaluated who are not intervened, and the weight of the patients to be evaluated who are not intervened is greater than the weight of the patients to be evaluated who are intervened. In the embodiment of the present invention, for the accuracy of subsequent calculations, the specific expression of the effective time series duration of the monitoring period is: In the formula, Represented as monitoring cycle The effective timing duration of Expressed as The number of cycles for each intervention patient to be evaluated, Expressed as The standardized value of the number of life episodes emitted by the patient to be evaluated during the monitoring period, Expressed as The number of cycles of patients who were not evaluated for intervention, Expressed as The standardized value of the number of life episodes emitted by the unintervention patients during the monitoring period, Expressed as the total number of monitoring cycles, It is expressed as the number of patients to be evaluated for intervention during the monitoring period, It is expressed as the number of patients who were not evaluated during the monitoring period. and Represented as the preset weight in the weighted sum, Less than In the embodiment of the present invention, the preset weight is 0.3, It should be noted that standardization is a technical means well known to those skilled in the art and will not be described in detail here.

[0040] in, Expressed as The effective time series of the intervention for each patient to be evaluated, Expressed as The effective time series duration of the unassessed patients who have not been evaluated is comprehensively processed by weighted summation to deal with the impact of the intervention status of the patients to be evaluated on the effective time series duration, and more consideration is given to the goals of new patients to be evaluated. The impact of irrelevant life segments with low temporal variability is also minimized, making the processing of confidence weights of subsequent life segments more accurate.

[0041] The spatial processing unit S103 is used to obtain the spatial correction factor of the candidate scene in each monitoring cycle based on the POI change rate and the interactive population change rate of all life fragments in the candidate scene; and obtain the life fragment neurogenic intestinal dysfunction assessment parameters of the candidate scene in the monitoring cycle based on the spatial correction factor of the candidate scene and the effective time series duration in the corresponding monitoring cycle.

[0042] Based on the time series change processing unit S102, the life fragments of the overall daily activities are comprehensively processed to obtain the effective time series duration in each monitoring cycle, and the life fragments in the candidate scenes in each monitoring cycle are further processed in detail, that is, comprehensive information processing is performed across states, and the text scene and the rate of change of willingness reflected by the time series changes of the patient's behavior to be evaluated are combined to comprehensively judge the spatial situation of the patient to be evaluated in each life fragment. The present invention mainly takes into account that the patients to be evaluated who output life fragments have a certain degree of subjectivity, and different patients to be evaluated have different spatial tendencies for different life fragments. When the patients to be evaluated recognize the content of the life fragments, a good quality of daily activities can be maintained. Therefore, by processing the spatial tendencies of the life fragments of the candidate scenes in the monitoring cycle with efficient time series changes, the life fragment neurogenic intestinal dysfunction evaluation parameters of the life fragments of the candidate scenes can be obtained, which specifically include: The number of POIs of all life fragments in the candidate scenes in the monitoring period is summarized, and the number of POIs reflects the change rate of the patient's recognition of the candidate scene life fragments. The standardized average value of all POI numbers is calculated as the positive space correction factor. The positive space correction factor can be used to see the POI change rate of the candidate scene life fragments in the corresponding monitoring period. The higher the POI change rate, the higher the change rate of the candidate scene life fragments recognized, and the higher the text quality of the reference life fragments. In the embodiment of the present invention, the expression of the positive space correction factor is: In the formula, Representing candidate scenes In the monitoring cycle The positive spatial correction factor on Represented as a candidate scene Middle The number of POIs in the life clips, It is represented by the total number of life fragments in the candidate scene. Expressed as a natural constant, It is expressed as an adjustment constant. In the embodiment of the present invention, it is deployed as 0.1 for the purpose of adjusting the normalization range to prevent the normalization range from being too close to 0, resulting in inaccurate calculation results. The specific value can be adjusted by the implementer.

[0043] in, It is expressed as the sum of the standardized number of POIs to obtain the overall number of POIs in the candidate scene. The average number of POIs in the life fragments of the candidate scene is further calculated as the positive space adjustment coefficient. The positive space adjustment coefficient reflects the positive space change rate of the candidate scene during the monitoring period. If the positive space change rate is larger, it means that the life fragments of the candidate scene have better positivity.

[0044] At the same time, the change rate of the negative spatial impact of the life fragments in the candidate scenes is also taken into account. The number of alienated people in all life fragments in the candidate scenes during the monitoring period is summarized. The number of alienated people reflects the change rate of the emotions of the evaluated patients towards the life fragments in the candidate scenes. The negative spatial change rate of the candidate scenes is processed through the number of interacted people in the candidate scenes during the monitoring period.

[0045] The number of alienations is standardized to obtain the reverse space correction factor, which can reflect the rate of change of the emotion of the patient to be evaluated in daily activities to the candidate scene life fragment during the monitoring period. The greater the rate of change of the emotion of the candidate scene life fragment, the worse the quality of the candidate scene life fragment, and the less likely the life fragment target expressed therein is to be the real target of the patient to be evaluated, so the confidence weight is also lower. In the embodiment of the present invention, the specific expression of the reverse space adjustment coefficient is: In the formula, Represented as a candidate scene In the monitoring cycle The inverse spatial correction factor on Represented as candidate scene life segments in the monitoring cycle The number of alienations on It is expressed as the total number of alienated life segments in the candidate scenes, It is expressed as a constant coefficient. In the embodiment of the present invention, the value is set to 0.01, in order to prevent the denominator from being zero, which makes the formula meaningless.

[0046] By performing normalization in the form of the maximum value divided by the quotient, the inverse spatial adjustment coefficient is obtained to reflect the negative spatial change rate of the candidate scene life segment in the monitoring period. The more alienated the candidate scene is in each monitoring period, the worse the spatial information expressed by the candidate scene life segment in the corresponding monitoring period, and the confidence weight of the corresponding candidate scene life segment is also lower. In other embodiments, minimum value normalization or standard normalization methods may also be used, which are not limited here.

[0047] Finally, the space correction factor is determined based on the positive space correction factor and the reverse space correction factor. In one embodiment of the present invention, the reverse space correction factor after negative correlation mapping and normalization is multiplied by the normalized positive space correction factor to obtain the space correction factor, that is, the positive space correction factor is positively correlated with the space correction factor, and the reverse space correction factor is negatively correlated with the space correction factor. The space correction factor is obtained by comprehensively combining the positive space adjustment coefficient and the reverse space adjustment coefficient. The space correction factor comprehensively reflects the spatial tendency of the candidate scene life segment. In an embodiment of the present invention, the specific expression of the space correction factor is: In the formula, Represented as a candidate scene In the monitoring cycle The spatial correction factor on Represented as a candidate scene In the monitoring cycle The positive spatial correction factor on Represented as a candidate scene In the monitoring cycle The inverse spatial correction factor on It is expressed as a normalization function. It should be noted that normalization is a technical means well known to those skilled in the art. The normalization function can be linear normalization or standard normalization, etc. The specific normalization method is not limited here.

[0048] When the positive spatial correction factor is larger and the reverse spatial correction factor is smaller, the spatial correction factor is larger, which means that the spatial tendency of the candidate scene life fragment is positive, which is more conducive to the development of public opinion on daily activities. When the positive spatial correction factor is smaller and the reverse spatial correction factor is larger, the spatial correction factor is smaller, which means that the spatial tendency of the candidate scene life fragment is negative, which is not conducive to the development of public opinion on daily activities, and the confidence weight needs to be reduced. In other embodiments of the present invention, other basic mathematical operations can be selected to reflect that the positive spatial correction factor is positively correlated with the spatial correction factor, and the reverse spatial correction factor is negatively correlated with the spatial correction factor, which will not be elaborated here.

[0049] After obtaining the spatial correction factor, the candidate scene life fragment is processed in combination with the effective time series duration in the monitoring cycle, and the life fragment neurogenic intestinal dysfunction evaluation parameter of the candidate scene in the monitoring cycle is obtained based on the spatial correction factor of the candidate scene and the effective time series duration in the corresponding monitoring cycle. The life fragment neurogenic intestinal dysfunction evaluation parameter can reflect the wonderful change rate of the candidate scene life fragment in the monitoring cycle, and the product of the spatial correction factor of the candidate scene in the monitoring cycle and the effective time series duration in the corresponding monitoring cycle is calculated as the life fragment neurogenic intestinal dysfunction evaluation parameter. When the effective time series duration in the monitoring cycle is higher, the corresponding spatial correction factor of the candidate scene is higher, and the life fragment neurogenic intestinal dysfunction evaluation parameter is larger. In an embodiment of the present invention, the specific expression of the life fragment neurogenic intestinal dysfunction evaluation parameter is: In the formula, Represented as a candidate scene In the monitoring cycle Parameters for assessing neurogenic intestinal dysfunction in a life story, Represented as a candidate scene In the monitoring cycle The spatial correction factor on Represented as monitoring cycle The effective timing duration.

[0050] The effective time series duration is adjusted by the spatial correction factor in the form of multiplication to obtain the life segment neurogenic intestinal dysfunction assessment parameters. The larger the spatial correction factor and the effective time series duration, the higher the quality of the neurogenic intestinal dysfunction assessment of the candidate scene life segment, and the higher the confidence weight of the candidate scene life segment as the true target life segment of the patient to be assessed. In other embodiments of the present invention, other basic mathematical operations such as addition can be used to reflect that the spatial correction factor and the effective time series duration are positively correlated with the life segment neurogenic intestinal dysfunction assessment parameters, which is not limited here.

[0051] At this point, by processing the spatial tendency of life fragments in the candidate scenes and combining them with the effective time series duration in each monitoring cycle, the life fragment neurogenic intestinal dysfunction evaluation parameters of the candidate scenes in each monitoring cycle are obtained. The life fragment neurogenic intestinal dysfunction evaluation parameters can be used to show the wonderful change rate of the life fragments in the candidate scenes. When the effective time series duration of the cycle in which the life fragments in the candidate scenes are located is high and the change rate recognized by other patients to be evaluated is large, it means that the candidate scenes have strong ability to evaluate neurogenic intestinal dysfunction in life fragments and the confidence weight of life fragments is improved.

[0052] The state information feature feedback unit S104 is used to obtain the life segment confidence weight of the candidate scene based on the execution time length of all life segments in the candidate scene corresponding to the patient to be evaluated and the life segment neurogenic intestinal dysfunction assessment parameters; obtain the final target life segment scene on the preset cycle based on the life segment confidence weight of all life segment application scenarios, and warn the nursing staff through the final target life segment scene.

[0053] In order to more accurately process the confidence weights of life fragments in candidate scenarios, the confidence weights of single life fragments in candidate scenarios are further refined according to the differences in behavioral information under different text information of life fragments. The confidence weight of each life fragment is optimized by outputting the execution time of the patient to be evaluated in the life fragment, and the feature representation is further adjusted in combination with different behavioral state information. The longer the patient to be evaluated performs daily activities, the more the patient to be evaluated knows the caregiver. Therefore, the confidence weight of the issued life fragment is higher and more in line with the atmosphere of the caregiver's daily activities, thereby improving the reliability of the final life fragment target extraction.

[0054] First, the execution time length of each life segment in the candidate scene corresponding to the patient to be evaluated is obtained. In an embodiment of the present invention, the method for collecting the execution time length is to mark the time node of the life segment corresponding to the ID of the patient to be evaluated, and traverse in reverse chronological order to the time node when the ID of the patient to be evaluated disappears, and take the period between the two time nodes as the execution time length of the patient to be evaluated, and the execution time length reflects the stay of the patient to be evaluated in daily activities.

[0055] In other embodiments of the present invention, the time point at which the patient ID to be evaluated requests to enter daily activities can be directly collected, and the execution time length can be obtained based on the entry time point of the patient to be evaluated and the output life fragment time point. The historical execution time length record of the patient to be evaluated in the daily activities can also be collected, and the standardized historical execution time length is used as the execution time length of the patient to be evaluated for calculation, and there is no limitation here. It should be noted that the daily activities based on the existence time of the patient ID to be evaluated and the collection of relevant information requests for the patient ID to be evaluated are public technical means well known to those skilled in the art, and will not be elaborated here.

[0056] In one embodiment of the present invention, a preset execution threshold value of 10 minutes is deployed, and the specific numerical value can be adjusted by the implementer based on the specific situation. Preferably, when the execution time length is greater than or equal to the preset execution threshold value, it means that the patient to be evaluated stays in daily activities for a long time, and the information of the output life fragment is highly reliable, and the preset first execution coefficient is used as an execution parameter, wherein the preset first execution coefficient is a value greater than or equal to 1. When the execution time length is less than the preset execution threshold value, it means that the patient to be evaluated does not stay in daily activities long enough, and the nursing staff does not have enough understanding of the current timing changes. The confidence weight of the corresponding life fragment information is adjusted, and the quotient of the execution time length and the preset execution threshold value is used as the execution parameter. It should be noted that since the quotient of the execution time length and the preset execution threshold value is a parameter less than 1, the value of the preset first execution coefficient needs to be greater than or equal to 1, and it is deployed as 1 in the embodiment of the present invention.

[0057] The confidence weight of each life segment of the candidate scene is adjusted by executing the parameters, specifically: the execution parameter of each life segment is multiplied by the life segment neurogenic intestinal dysfunction assessment parameter corresponding to the monitoring cycle of each life segment, to obtain the single life segment confidence weight of each life segment, and the confidence weight of a life segment in the candidate scene is corrected by the single life segment confidence weight, so that the obtained candidate scene life segment confidence weight is more accurate. In the embodiment of the present invention, the expression of the single life segment confidence weight is: In the formula, Expressed as The monitoring cycle of the life segment The confidence weight of a single life episode on Represented as a candidate scene In the monitoring cycle Parameters for assessing neurogenic intestinal dysfunction in a life story, Expressed as The length of time that each life segment corresponds to the patient to be evaluated. Indicates the preset execution threshold value. Represented as the preset first execution coefficient.

[0058] Through a piecewise function, the execution time length of each life segment corresponding to the patient to be evaluated is used as a weight to adjust the life segment neurogenic intestinal dysfunction assessment parameters, and the single life segment confidence weight of each life segment is obtained. The longer the execution time length of the patient to be evaluated is, the greater the single life segment confidence weight is. In other embodiments of the present invention, the execution time length of the patient to be evaluated can also be directly standardized to obtain the execution weight, and the single life segment confidence weight is obtained based on the execution weight and the life segment neurogenic intestinal dysfunction assessment parameters. However, in this embodiment, the confidence weight may increase too much due to the long execution time of some patients to be evaluated. However, the execution time at this time is not much, and increasing the confidence weight will produce a certain error, which is not as accurate as the method in the preferred embodiment of the present invention, so it will not be repeated here.

[0059] The single life segment confidence weights of all life segments of the candidate scene in the preset period are obtained, and the single life segment confidence weights of all life segments are added to obtain the life segment confidence weights of the candidate scene. The life segment confidence weights of the candidate scene can be used to judge the life segment target. The life segment confidence weights are obtained through the spatial tendency processing of the patient to be evaluated and the corrected comprehensive temporal change time of the execution time length of the patient to be evaluated. The life segment confidence weights can more comprehensively characterize the important change rate of the life segment with target information and the change rate of the patient's willingness to be evaluated, and reflect the life segment characteristics obtained by cross-state processing.

[0060] Furthermore, a method for obtaining life fragment confidence weights based on candidate scenarios can be used to obtain life fragment confidence weights for all life fragment application scenarios, and then the final target life fragment scenario in a preset period is obtained based on the life fragment confidence weights of all life fragment application scenarios for early warning. Specifically, the life fragment application scenario with the largest life fragment confidence weight is used as the final target life fragment scenario, and the life fragment scenario corresponding to the final target life fragment scenario is used as the early warning content to warn nursing staff in daily activities, thereby realizing the process of feedback based on fused life fragment features.

[0061] Among them, the life fragment application scenario with the largest life fragment confidence weight is the life fragment application scenario with a higher willingness of the patient to be evaluated in the preset period. The reliability of the final target life fragment scenario in comprehensively representing the target willingness of the patient to be evaluated is stronger. Therefore, in the embodiment of the present invention, the life fragment scenario corresponding to the final target life fragment scenario is used as the warning content and fed back to the nursing staff in daily activities. The life fragment confidence weight processing can more accurately and comprehensively reflect the comprehensive target situation of the patient to be evaluated within a period of time, so that the nursing staff can make the best adjustment.

[0062] In other embodiments, the life segment with the highest confidence weight in the final target life segment scene can also be used as the warning content for warning. It should be noted that when there are multiple life segments with the highest confidence weight, one of them can be randomly selected for warning, and there is no restriction here.

[0063] Through the final target life fragments fed back by the status characteristics, continuous early warning is provided to help nursing staff make adjustments in the subsequent time-series change links, etc., so as to achieve better daily life effects and improve the recovery effect of patients to be evaluated by meeting their real goals.

[0064] In summary, the present invention clusters and divides the scenarios of life fragments output by patients to be evaluated in the preset cycle of daily activities to obtain life fragment application scenarios, first processes the text, and processes the text status information, and further obtains the monitoring period based on the number change trend of all life fragments in the life fragment application scenario in the preset period, and then obtains the effective time series duration based on the intervention status of the patients to be evaluated in the monitoring period and the number of life fragments output. First, the change in the number of life fragments is processed as a whole, and the preset period is divided into several monitoring periods, that is, it is further processed based on the output behavior characteristics of the life fragments, and the behavior status information is processed. The effective time series duration in the monitoring period can be used to preliminarily screen out life fragments with time series change significance, thereby improving processing efficiency. In the monitoring cycle, the spatial correction factor is obtained based on the POI change rate and interactive population change rate of the patient to be evaluated in each life segment application scenario, and the effective time series duration is adjusted to obtain the life segment neurogenic intestinal dysfunction assessment parameters. The text state information and behavior state information are combined to reflect the time series change space of the patient to be evaluated in the life segments of different texts. By processing the spatial tendency of the patient to be evaluated, the quality of the target life segment finally extracted is higher and more in line with the wishes of the patient to be evaluated. Finally, based on the execution time length of each life segment corresponding to the patient to be evaluated in each life segment application scenario, the life segment neurogenic intestinal dysfunction assessment parameters are corrected to obtain the life segment confidence weight of each life segment application scenario. The life segment features are processed again through multi-state information to obtain a more reliable life segment confidence weight, and then the final target life segment scene is extracted more accurately and more in line with the wishes of the patient to be evaluated. The final target life segment scene is used to warn daily life, so that the nursing staff can bring more daily life effects after adjustment, improve the recovery effect of the patient to be evaluated, improve the reliability of the life segment target feature extraction method, and reduce the target feature extraction error.

[0065] The present invention also provides a method for evaluating neurogenic intestinal dysfunction, referring to Figure 2 ,include: S1: Collect life fragments output by the patient to be evaluated during a preset period of daily activities, cluster and divide the life fragments based on the life fragment scenarios, obtain life fragment application scenarios, and randomly select one of the life fragment application scenarios as a candidate scenario; S2: Based on the change trend of the number of all life segments in the life segment application scenario, a monitoring period on a preset period is obtained; in the monitoring period, based on the intervention status of all patients to be evaluated and the number of life segment outputs, an effective time series duration on the monitoring period is obtained; S3: In each monitoring cycle, based on the POI change rate and interactive population change rate of all life segments in the candidate scene, the spatial correction factor of the candidate scene in the monitoring cycle is obtained; based on the spatial correction factor of the candidate scene and the effective time series duration of the corresponding monitoring cycle, the neurogenic intestinal dysfunction assessment parameters of the life segments of the candidate scene in the monitoring cycle are obtained; S4: Based on the execution time length of all life segments in the candidate scenarios corresponding to the patients to be evaluated and the life segment neurogenic intestinal dysfunction assessment parameters, the life segment confidence weights of the candidate scenarios are obtained; based on the life segment confidence weights of all life segment application scenarios, the final target life segment scenario on the preset cycle is obtained, and the nursing staff is warned through the final target life segment scenario.
