[0053] An artificial anal canal status monitoring score is determined based on the drainage fluid volume, the standard drainage fluid volume, the patient recovery stage vector, the stoma patency identification result, the stoma skin identification result, the color identification result and the trait identification result.

[0054] For example, an image of the stoma area is captured by a camera; the amount of drainage fluid discharged (drainage fluid amount) is obtained, and an image of the discharged drainage fluid (drainage fluid image) is captured; based on the drainage fluid image, the color and properties of the drainage fluid are identified and judged, and the color recognition result and the property recognition result are determined; based on the stoma image, the patency of the stoma and the condition of the skin around the stoma are judged, and the patency recognition result and the stoma skin recognition result are determined; based on the patient's personal information, the patient's recovery environment temperature (e.g., the temperature of the patient's ward is 26 degrees Celsius), the patient's food intake, the patient's activity level (e.g., the patient's activity level determined based on the number of steps recorded by the sports software), the patient's age, the patient's gender, and the patient's surgery are determined. Time (e.g., the patient's surgery date is 1.1); according to the patient's surgery time, determine the patient's recovery stage, for example, if the patient's surgery date is 1.1, if the current date is 1.2 (within 72 hours after surgery), the patient's recovery stage is the early postoperative stage; if the current date is 1.5 (3-14 days after surgery), the patient's recovery stage is the postoperative recovery stage; if the current date is 2.1, the patient's recovery stage is the long-term follow-up stage; according to the patient's recovery stage, determine the patient's recovery stage vector, for example, when the patient's recovery stage is the early postoperative stage, the patient's recovery stage vector is (1,0,0); when the patient's recovery stage is the postoperative recovery stage, the patient's recovery stage vector is (1,0,0). is (0,1,0), when the patient's recovery stage is the long-term follow-up stage, the patient's recovery stage vector is (0,0,1); perform routine examinations on patients to obtain the patient's albumin content and blood glucose content; determine similar historical patients based on the patient's age and gender, for example, if the patient is 60 years old and the patient's gender is male, then patients aged 58-62 years old and male are determined as similar historical patients; obtain the historical drainage volume, historical patient food intake, historical patient recovery environment temperature, historical patient activity, historical patient albumin content and historical patient blood glucose content of similar historical patients with normal recovery status in the long-term follow-up stage after surgery; the drainage volume is to a certain extent It is related to the patient's food intake, the patient's recovery environment temperature, the patient's activity level, the patient's albumin content and the patient's blood glucose content. For example, when the patient eats more, the drainage fluid volume is also more. Based on the correlation of the above data, the drainage fluid volume relationship function can be determined; the patient's food intake, the patient's activity level, the patient's albumin content and the patient's blood glucose content are substituted into the drainage fluid volume relationship function to determine the patient's normal drainage fluid volume in the long-term follow-up stage, that is, the standard drainage fluid volume; according to the drainage fluid volume, the standard drainage fluid volume, the patient's recovery stage vector, the stoma patency recognition result, the stoma skin recognition result, the color recognition result and the trait recognition result, the patient's artificial anal tube status is evaluated to determine the artificial anal tube status monitoring score.

[0055] According to one embodiment of the present invention, determining a stoma patency recognition result, a stoma skin recognition result, a color recognition result, and a property recognition result based on the drainage fluid image and the stoma image includes:

[0056] In the drainage fluid image, identifying whether the color of the drainage fluid is abnormal through an image detection model, and determining a color recognition result;

[0057] In the drainage fluid image, identifying whether there is an abnormality in the properties of the drainage fluid through an image detection model, and determining a property recognition result;

[0058] In the stoma image, identifying whether the stoma is unobstructed by using an image detection model, and determining a stoma unobstructed identification result;

[0059] In the stoma image, an image detection model is used to identify whether there is abnormality in the skin around the stoma, and a stoma skin recognition result is determined.

[0060] For example, the image detection model is a type of deep learning model. The image detection model is trained through historical data so that the image detection model can identify the color of the drainage fluid, the properties of the drainage fluid, the patency of the stoma, and the skin condition around the stoma in the image; in the drainage fluid image, the image detection model is used to identify whether the color of the drainage fluid is abnormal, and the color recognition result is determined. When the color of the drainage fluid is yellow or light green, there is no abnormality in the color of the drainage fluid, and the color recognition result is 1. When the color of the drainage fluid is bloody, it indicates that there may be anastomotic bleeding or intestinal damage, and the color of the drainage fluid is abnormal, and the color recognition result is 0; in the drainage fluid image, the image detection model is used to identify whether the properties of the drainage fluid are abnormal, and the property recognition result is determined. When the properties of the drainage fluid are normal liquid, the properties of the drainage fluid are normal. If there is no abnormality in the drainage fluid, the property recognition result is 1. When the drainage fluid property is pus or mucus, it indicates that anastomotic fistula or abdominal infection may occur, and the drainage fluid property is abnormal, then the property recognition result is 0. In the stoma image, the image detection model is used to identify whether the stoma is unobstructed, and the stoma patency recognition result is determined. If the stoma is unobstructed and there is no blockage, retraction or prolapse, the stoma patency recognition result is 1. If the stoma is not unobstructed, the stoma patency recognition result is 0. In the stoma image, the image detection model is used to identify whether there is an abnormality in the skin around the stoma, and the stoma skin recognition result is determined. If there is no redness, swelling, exudation or ulceration in the skin around the stoma, the stoma skin recognition result is 1. If there is redness, swelling, exudation or ulceration in the skin around the stoma, the stoma skin recognition result is 0.

[0061] According to one embodiment of the present invention, the drainage fluid volume relationship function is determined according to the historical drainage fluid volume, the historical patient food intake, the historical patient activity, the historical patient recovery environment temperature, the historical patient albumin content and the historical patient blood glucose content, including: determining the first undetermined coefficient equation of the drainage fluid volume relationship function according to formula (1), (1),

[0062] The h in the subscript of each parameter indicates that the parameter is historical data. is the historical drainage volume of the kth similar historical patient on the i-th historical date, is the food intake of the kth similar historical patient on the i-th historical date, is the historical patient activity of the kth similar historical patient on the i-th historical date, is the albumin content of the kth similar historical patient on the i-th historical date, Recover the ambient temperature for the historical patient of the kth similar historical patient at the i-th historical date, is the blood glucose content of the kth similar historical patient on the i-th historical date, , , , , , , , , and is the first undetermined coefficient of the first undetermined coefficient equation;

[0063] Solving the first undetermined coefficient according to the historical drainage fluid volume, the historical patient food intake, the historical patient activity level, the historical patient recovery environment temperature, the historical patient albumin content, and the historical patient blood sugar content to obtain a solution value of the first undetermined coefficient;

[0064] The drainage fluid volume relationship function is determined according to the solved value of the first undetermined coefficient and the first undetermined coefficient equation.

[0065] According to one embodiment of the present invention, It means that the historical drainage volume of the kth patient with similar history on the ith historical date is positively correlated with the historical food intake of the kth patient with similar history on the ith historical date. For example, excessive food intake stimulates the secretion of bile and pancreatic juice, increases the amount of intestinal fluid, and may lead to an increase in drainage fluid. It means that the historical drainage volume of the kth patient with similar history on the i-th historical date is positively correlated with the historical activity of the kth patient with similar history on the i-th historical date. For example, if the activity is large, the secretions will flow to the lower position due to gravity, resulting in an increase in the drainage volume. It means that the historical drainage volume of the k-th patient with similar history on the i-th historical date is positively correlated with the blood sugar content of the k-th patient with similar history on the i-th historical date. For example, the higher the blood sugar, the easier it is to induce anastomotic infection, increase the exudate, and lead to an increase in drainage volume. It means that the historical drainage volume of the k-th similar historical patient on the i-th historical date is negatively correlated with the historical albumin content of the k-th similar historical patient on the i-th historical date. For example, the lower the albumin content, the lower the plasma colloid osmotic pressure, the more interstitial fluid exudation, and the more drainage volume. It means that the historical drainage volume of the kth similar historical patient on the ith historical date is negatively correlated with the historical patient recovery environment temperature of the kth similar historical patient on the ith historical date. For example, the lower the ambient temperature, the more likely it is to stimulate intestinal contraction, increase secretion discharge, and lead to an increase in drainage volume. Based on the above relationship, the first undetermined coefficient equation of the drainage volume relationship function can be obtained.

[0066] According to one embodiment of the present invention, fitting can be performed based on multiple parameters involved in the above first undetermined coefficients, that is, fitting can be performed based on historical drainage volume, historical patient food intake, historical patient activity, historical patient recovery environment temperature, historical patient albumin content and historical patient blood sugar content to solve the above multiple first undetermined coefficients. There are 10 first undetermined coefficients, namely, , , , , , , , , and , solve the above 10 first undetermined coefficients according to the historical drainage fluid volume, historical patient food intake, historical patient activity, historical patient recovery environment temperature, historical patient albumin content and historical patient blood glucose content of at least 10 similar historical patients, obtain the solution values ​​of the above 10 first undetermined coefficients, and substitute the solution values ​​of the above 10 first undetermined coefficients into the first undetermined coefficient equation to determine the drainage fluid volume relationship function.

[0067] In this way, the drainage fluid volume relationship function can be determined based on the historical drainage fluid volume, historical patient food intake, historical patient activity, historical patient recovery environment temperature, historical patient albumin content and historical patient blood glucose content, accurately describing the relationship between the patient's food intake, patient activity, patient recovery environment temperature, patient albumin content, patient blood glucose content and the drainage fluid volume, thereby improving the accuracy and objectivity of the drainage fluid volume relationship function.

[0068] According to one embodiment of the present invention, the artificial anal canal status monitoring score is determined according to the drainage fluid volume, the standard drainage fluid volume, the patient recovery stage vector, the stoma patency recognition result, the stoma skin recognition result, the color recognition result and the property recognition result, including: determining the artificial anal canal status monitoring score of the jth patient on the rth day after surgery according to formula (2): , ,

[0070] According to one embodiment of the present invention, is the product of the patient recovery stage vector of the j-th patient and the transpose of the vector determined according to the standard drainage fluid volume, the first preset drainage fluid volume threshold, and the second preset drainage fluid volume threshold. When the j-th patient is in the early postoperative stage, The value of , when the jth patient is in the postoperative recovery stage, The value of , when the jth patient is in the long-term follow-up phase, The value of ,in, The first preset drainage volume threshold is: in the early postoperative stage, if the drainage volume is too small (e.g., less than 20 ml), it indicates the possibility of intestinal paralysis; if the drainage volume is too large (e.g., greater than 200 ml), it indicates the risk of anastomotic leakage. The value can be set to 110ml (the average of the lower limit of normal drainage volume (20ml) and the upper limit of normal drainage volume (200ml)). The second preset drainage volume threshold is: during the postoperative recovery phase, if the drainage volume is too small (e.g., less than 50 ml), it indicates that intestinal paralysis may occur; if the drainage volume is too large (e.g., greater than 300 ml), it indicates that infectious diarrhea or short bowel syndrome may occur. The value can be set to 175ml, is the standard drainage volume of the jth patient, represents the standard drainage volume of the jth patient in the long-term follow-up stage, is the standard drainage volume determined according to the recovery stage of the jth patient.

[0071] According to one embodiment of the present invention, is the relative difference between the drainage volume discharged by the jth patient at the e-th drainage on the r-th day after surgery and the standard drainage volume determined according to the recovery stage of the jth patient. The smaller the ratio, the smaller the difference between the drainage volume discharged by the jth patient at the e-th drainage on the r-th day after surgery and the standard drainage volume in the corresponding recovery stage, and the better the patient's artificial anal tube condition. The ratio is calculated based on the number of drainage fluid discharges. The larger the ratio is, the better the status of the artificial anal tube of the jth patient on the rth day after surgery is. It is the relative difference between the amount of drainage fluid discharged by the jth patient during the e-th drainage on the r-th day after surgery and the amount of drainage fluid discharged by the jth patient during the e+1-th drainage on the r-th day after surgery. The larger the ratio, the more rapid or rapid decrease in the amount of drainage fluid discharged, which may lead to infection risk.

[0072] According to one embodiment of the present invention, The artificial anal tube status monitoring score is determined based on the patient's drainage fluid output, drainage fluid color, drainage fluid properties, stoma patency and skin condition around the stoma.

[0073] In this way, the artificial anal canal status monitoring score can be determined based on the drainage fluid volume, standard drainage fluid volume, patient recovery stage vector, stoma patency identification results, stoma skin identification results, color identification results and property identification results. During the calculation process, the artificial anal canal status can be evaluated based on five aspects: the patient's drainage fluid discharge volume, drainage fluid color, drainage fluid properties, stoma patency and skin condition around the stoma, thereby improving the accuracy and comprehensiveness of the artificial anal canal status monitoring score.

If there is an abnormality in the anastomosis image of the jth patient on the rth day after surgery, the state of the natural anal canal is poor. The value is 0, otherwise The value of is 1.

[0088] According to one embodiment of the present invention, To determine the anal canal status monitoring score based on the fecal calprotectin level, C-reactive protein level, patient's subjective feeling and anastomotic imaging.

[0089] In this way, the anal canal status monitoring score can be determined based on the pain identification results, anastomosis identification results, fecal calprotectin content and C-reactive protein content. During the calculation process, the patient's anal canal status can be evaluated based on four aspects: fecal calprotectin content, C-reactive protein content, patient's subjective feeling and anastomosis imaging status, thereby improving the comprehensiveness and accuracy of the anal canal status monitoring score.

[0090] According to an embodiment of the present invention, in step S106, a monitoring report is generated according to the artificial anal canal state monitoring score and the anal canal state monitoring score.

[0091] For example, when the artificial anal canal status monitoring score is less than the set artificial anal canal status monitoring score threshold (e.g., + + + + ), it indicates that there is an abnormality in the artificial anal canal; when the anal canal status monitoring score is less than the set anal canal status monitoring score threshold (e.g., 1), it indicates that there is an abnormality in the natural anal canal.
