Description

Technical Field

[0001] The present invention relates to the field of medical technologies, and particularly to a visual pain assessment report system and method. Background Art

[0002] The International Association for the Study of Pain defines "pain" as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or a description of such damage". Given the various harms of pain to patients, pain has been listed as the fifth vital sign internationally. In a clinical setting, pain is difficult to assess and manage, and pain assessment is an important part of pain control and an important reference factor in medical diagnosis.

[0003] Currently, there is a lack of a complete pain assessment system in hospitals, making it difficult to visually assess a patient's pain based on the pain time, pain frequency of the patient, and the patient's real-time physiological data (such as heart rate, blood pressure, respiratory rate, etc.), which poses an obstacle to the diagnosis of the patient's illness.

[0004] When relieving a patient's pain, painkillers are usually required. Currently, the pain assessment systems in the existing technologies are difficult to adjust the dosage of painkillers according to the patient's pain sensation and different physical factors (age, weight, etc.) of different patients. When the dosage is small, the pain relief effect is poor, while when the dosage is high, it will bring certain negative effects to the patient's body.

[0005] Therefore, there is an urgent need for a visual pain assessment report system and method to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a visual pain assessment report system and method to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides a visual pain assessment report system, including:

[0008] A data collection module, configured to measure the pain intensity Pi of a patient by the numerical rating scale, record the pain time Pct, measure the patient's heart rate HR, patient's systolic blood pressure SBP, patient's diastolic blood pressure DBP, and patient's respiratory rate RR through an electrocardiogram monitor, and upload them to a database together;

[0009] It is configured to obtain the patient's weight We, patient's age Age, and gender from a hospital information system and upload them to the database;

[0010] A data preprocessing module, configured to perform decoding and preprocessing on the data information in the database to obtain the parameters participating in the calculation in a calculation processing module;

[0011] A calculation and processing module, configured to input the parameters obtained after decoding and preprocessing into a basic pain value algorithm unit to calculate a basic pain value Pd;

[0012] configured to input the basic pain value Pd as an input parameter into a comprehensive pain value algorithm unit and calculate a comprehensive pain value Ps in combination with the patient's real-time physiological data;

[0013] configured to input the comprehensive pain value Ps into a planned drug dosage algorithm unit to calculate a planned drug dosage Dp and upload it to a database;

[0014] configured to perform parameter adjustment through a feedback adjustment unit.

[0015] Optionally, the parameter adjustment specifically includes:

[0016] When the planned drug dosage Dp is greater than twice the basic drug dosage Db, adjust the value of the correction factor α in the comprehensive pain value algorithm unit, and the adjustment formula is as follows:

[0017] ;

[0018] In the formula calculation:

[0019] When Dp is greater than 2×Db, in the calculation of the n + 1 cycle, the value of the correction factor α decreases linearly with the increase of the planned drug dosage Dp in the n cycle, that is, when the drug is excessive, reduce the comprehensive pain value Ps in the calculation of the next cycle to avoid over-reliance on drug treatment.

[0020] Optionally, the calculation and processing module includes a basic pain value algorithm unit, a comprehensive pain value algorithm unit, a planned drug dosage algorithm unit, and a feedback adjustment unit.

[0021] Optionally, the basic pain value algorithm unit is as follows:

[0022] ;

[0023] Wherein:

[0024] Pd represents the basic pain value;

[0025] Pi represents the pain intensity, which is the intensity of the i-th pain of the patient in a day;

[0026] Pct represents the pain time, which is the time of the i-th pain of the patient in a day;

[0027] N represents the number of pain times, which is the number of pain attacks of the patient in a day;

[0028] Sp represents the sensitivity coefficient, which is the sensitivity coefficient of the i-th pain of the patient in a day and is used to adjust the pain severity according to the patient's pain location, and Sp ∈ [0.6, 1.2];

[0029] In the formula calculation:

[0030] This part reflects the degree of aggravation of the influence of high pain intensity Pi on the basic pain value Pd through the power function, increasing the basic pain value Pd calculated by the patient in severe pain;

[0031] This part performs logarithmic processing on the pain time Pct. As the pain time Pct increases, the basic pain value Pd will increase, but the growth rate will slow down, reducing the excessive influence of long-term pain on the calculation of the basic pain value Pd while ensuring that the pain time Pct has a positive impact on the calculated result of the basic pain value Pd;

[0032] Multiply the intensity of the i-th pain taken to the power of 1.2 by After multiplying this influencing term of the pain time Pct by the sensitivity coefficient Sp, the pain value of the i-th time is obtained. The multiple pain values within a day are added up and divided by the number of pain times N to obtain the average basic pain value Pd within a day.

[0033] Optionally, the comprehensive pain value algorithm unit is as follows:

[0034] ;

[0035] Where:

[0036] Ps represents the comprehensive pain value;

[0037] Pd represents the basic pain value;

[0038] HR represents the patient's heart rate;

[0039] SBP represents the patient's systolic blood pressure;

[0040] DBP represents the patient's diastolic blood pressure;

[0041] RR represents the patient's respiratory rate;

[0042] HRnorm represents the reference value of the heart rate health value;

[0043] SBPnorm represents the reference value of the systolic blood pressure health value;

[0044] DBPnorm represents the reference value of the diastolic blood pressure health value;

[0045] RRnorm represents the reference value of the respiratory rate health value;

[0046] α represents the correction factor, with a basic value of 1, and it is self-adjusted in the pain assessment report system;

[0047] In formula calculation:

[0048] This part represents the influencing term of the patient's heart rate HR on the calculation of the comprehensive pain value Ps. The numerator part takes the absolute value after subtracting the reference value HRnorm of the healthy heart rate from the patient's heart rate HR, representing the degree of deviation of the patient's heart rate HR from the healthy value. The constant 2 in the numerator part is regarded as dividing the denominator part by 1 / 2. This part serves as the denominator, representing the maximum allowable deviation degree of the patient's heart rate HR. It is obtained by dividing the numerator by the denominator. This part normalizes the degree of deviation of the patient's heart rate HR from the healthy value to the range of 0 to 1. When the patient's heart rate HR approaches the reference value HRnorm of the healthy heart rate, the influencing value of the patient's heart rate HR in this part tends to 0, indicating that the patient's heart rate HR will not affect the calculation of the comprehensive pain value Ps. As the degree of deviation of the patient's heart rate HR from the reference value HRnorm of the healthy heart rate becomes greater, the numerator becomes larger, and the calculated comprehensive pain value Ps is higher.

[0049] The influencing ways of the patient's systolic blood pressure SBP, diastolic blood pressure DBP, and respiratory rate RR on the calculation of the comprehensive pain value Ps are the same as that of the patient's heart rate HR. After adding the influencing terms of these four indicators and multiplying by one-fourth, the comprehensive influencing term based on physiological indicators is obtained. After adding 1 to this part of the comprehensive influencing term and multiplying by the basic pain value Pd, the adjusted comprehensive pain value Ps based on physiological indicators is obtained.

[0050] Optionally, the planned drug dosage algorithm unit is as follows:

[0051] ;

[0052] Where:

[0053] Dp represents the planned drug dosage;

[0054] Db represents the basic drug dosage;

[0055] We represents the patient's weight;

[0056] Age represents the patient's age;

[0057] Sa represents the gender adjustment factor;

[0058] Ps represents the comprehensive pain value;

[0059] In formula calculation:

[0060] This part represents the influencing term of the patient's weight We on the calculated planned drug dosage Dp. Dividing the patient's weight by the standard weight of 70 reflects the linear influence of the patient's weight We on the calculated planned drug dosage Dp. As the patient's weight We increases, the calculated planned drug dosage Dp increases;

[0061] This part represents the influencing term of the patient's age Age on the calculated planned drug dosage Dp. Specifically:

[0062] When the patient's age Age ≥ 30, taking 30 years old as the benchmark, the dosage decreases by 0.5% for each additional year. When the patient's age Age is less than 30, take the minimum value of the patient's age Age, which is 30. At this time The value of this part is 1, representing young and middle-aged patients under 30 years old, and age will not affect the calculation of the planned drug dosage Dp;

[0063] This part represents the influencing term of the patient's pain on the planned drug dosage Dp. The value range of the hyperbolic tangent function tanh is (-1, 1). After adding 1, The value range of this part is (0, 2). The constant 5 is the pain good threshold of the comprehensive pain value Ps. Specifically:

[0064] When the comprehensive pain value Ps is greater than 5, as the comprehensive pain value Ps increases, the value of this part of the tangent function tanh approaches 1, representing that as the patient's comprehensive pain value Ps increases, the required drug dosage is twice the basic drug dosage Db;

[0065] When the comprehensive pain value Ps is less than 5, as the comprehensive pain value Ps decreases, the value of this part of the tangent function tanh approaches -1, The calculated value approaches 0, representing that as the patient's comprehensive pain value Ps continues to decrease below the pain good threshold, the patient's recovery is better and the pain reliever dosage is close to 0.

[0066] Optionally, the devices used in the data collection module include an electrocardiogram monitor.

[0067] A visual pain assessment report system includes the following steps:

[0068] Measure the patient's pain intensity Pi through the numerical rating scale in the data collection module and record the pain time Pct. Measure the patient's heart rate HR, patient's systolic blood pressure SBP, patient's diastolic blood pressure DBP, and patient's respiratory rate RR through an electrocardiogram monitor, and upload them to the database together;

[0069] Obtain the patient's weight We, patient's age Age, and gender from the hospital information system and upload them to the database;

[0070] The data information in the database is decoded and preprocessed by the data preprocessing module to obtain the parameters for calculation in the calculation processing module;

[0071] The parameters obtained after decoding and preprocessing are input into the basic pain value algorithm unit in the calculation processing module to calculate the basic pain value Pd;

[0072] The basic pain value Pd is used as an input parameter and input into the comprehensive pain value algorithm unit in the calculation processing module, and combined with the patient's real-time physiological data to calculate the comprehensive pain value Ps;

[0073] The comprehensive pain value Ps is input into the planned drug dosage algorithm unit in the calculation processing module to calculate the planned drug dosage Dp and upload it to the database;

[0074] Parameter adjustment is performed through the feedback adjustment unit in the calculation processing module, specifically including:

[0075] When the planned drug dosage Dp is greater than twice the basic drug dosage Db, the value of the correction factor α in the comprehensive pain value algorithm unit is adjusted;

[0076] According to the calculated planned drug dosage Dp, the painkiller dosage for the patient on the next day is adjusted.

[0077] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0078] First, through the mutual cooperation of three groups of algorithm units, the present invention jointly constitutes the core architecture of the visual pain assessment report system. By comprehensively considering the pain intensity Pi, pain time Pct, and sensitivity coefficient Sp, the basic pain value Pd is calculated, and combined with the patient's real-time physiological data (such as heart rate, blood pressure, etc.), the comprehensive pain value Ps is calculated, providing a more comprehensive and detailed visual pain assessment. Compared with relying solely on the patient's subjective description, this pain assessment method can more accurately reflect the patient's actual pain condition. By analyzing the comprehensive pain value Ps of patients at different time points in the database of the pain assessment report system and generating a visual report, doctors can more intuitively explain the patient's pain condition and treatment plan to the patient, and patients can also intuitively understand their own pain condition and treatment effect through the visual pain assessment report system, improving the patient's treatment efficiency and being beneficial to the recovery of the patient's condition.

[0079] II. The planned dosage algorithm unit of the present invention comprehensively considers the basic dosage Db, the patient's weight We, and the comprehensive pain value Ps to calculate the planned dosage Dp, which can better meet the specific needs of each patient, ensure that the patient receives appropriate drug treatment, avoid underdosage or overdose, thereby improving the treatment effect and reducing the risk of adverse reactions. Moreover, since the patient's pain condition and physiological indicators (heart rate, blood pressure, etc.) can be obtained in real-time and updated in the pain assessment report system, the planned dosage Dp can be dynamically adjusted according to the actual situation. This dynamic adjustment method can ensure the continuous effectiveness of the treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] Figure 2 is a schematic diagram of the modules of a visual pain assessment reporting system. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0082] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0083] Embodiment 1. Please refer to Figures 1 to 2 , the present invention provides a visual pain assessment reporting system, including:

[0084] A data collection module for measuring the patient's pain intensity Pi by the numerical rating scale, recording the pain time Pct, measuring the patient's heart rate HR, systolic blood pressure SBP, diastolic blood pressure DBP, and respiratory rate RR of the patient by an electrocardiogram monitor, and uploading them to the database together;

[0085] For obtaining the patient's weight We, age Age, and gender from the hospital information system and uploading them to the database;

[0086] A data preprocessing module for decoding and preprocessing the data information in the database to obtain the parameters participating in the calculation in the calculation processing module;

[0087] A calculation processing module for inputting the parameters obtained after decoding and preprocessing into the basic pain value algorithm unit to calculate the basic pain value Pd;

[0088] For inputting the basic pain value Pd as an input parameter into the comprehensive pain value algorithm unit and calculating the comprehensive pain value Ps in combination with the patient's real-time physiological data;

[0089] For inputting the comprehensive pain value Ps into the planned drug dosage algorithm unit to calculate the planned drug dosage Dp and uploading it to the database;

[0090] For parameter adjustment through the feedback adjustment unit, specifically including:

[0091] When the planned drug dosage Dp is greater than twice the basic drug dosage Db, adjust the value of the correction factor α in the comprehensive pain value algorithm unit. The adjustment formula is as follows:

[0092] ;

[0093] In the formula calculation:

[0094] When Dp is greater than 2×Db, in the calculation of the (n + 1)th cycle, the value of the correction factor α decreases linearly with the increase of the planned drug dosage Dp in the nth cycle, that is, when the drug is in excess, the comprehensive pain value Ps in the next cycle calculation is reduced, avoiding over-reliance on drug treatment.

[0095] In this embodiment:

[0096] Through the mutual cooperation of multiple groups of algorithm units, the present invention jointly constitutes a visual pain assessment report system, comprehensively considering the pain intensity Pi, pain time Pct, pain frequency, and sensitivity coefficient Sp, calculating the basic pain value Pd, and combining the patient's real-time physiological data (such as heart rate, blood pressure, respiratory rate, etc.) to calculate the comprehensive pain value Ps, providing a more comprehensive and detailed visual pain assessment. Compared with relying solely on the patient's subjective description or the doctor's simple scoring, this pain assessment method can more accurately reflect the patient's actual pain condition, helping medical staff better understand the patient's pain condition. By analyzing the comprehensive pain value Ps of patients at different time points in the database of the pain assessment report system and generating a visual report, doctors can more intuitively explain the patient's pain condition and treatment plan to the patient, and patients can also intuitively understand their own pain condition and treatment effect through the visual pain assessment report system, improving the patient's treatment efficiency and being beneficial to the recovery of the patient's condition.

[0097] Moreover, the present invention calculates the planned dosage Dp through the planned dosage algorithm unit by comprehensively considering the basic dosage Db, the patient's weight We, the patient's age Age, and the comprehensive pain value Ps, which can better meet the specific needs of each patient. This helps to ensure that patients receive appropriate drug treatment, avoid under-dosage or over-dosage situations, thereby improving the treatment effect and reducing the risk of adverse reactions. And since the patient's pain condition and physiological indicators (heart rate, blood pressure, etc.) can be updated and obtained in real time in the pain assessment report system, the planned dosage Dp can be dynamically adjusted according to the actual situation. This dynamic adjustment method can ensure the continuous effectiveness of the treatment.

[0098] Please refer to Figures 1 to 2 , the basic pain value algorithm unit is as follows:

[0099] ;

[0100] Where:

[0101] Pd represents the basic pain value;

[0102] Pi represents the pain intensity, which is the intensity of the patient's i-th pain within a day, measured by the doctor through the numerical rating scale, and Pi ∈ [0, 10];

[0103] Pct represents the pain time, which is the time of the patient's i-th pain within a day, and the unit is minutes;

[0104] N represents the number of pain episodes, which is the number of pain attacks of the patient within a day;

[0105] Sp represents the sensitivity coefficient, which is the sensitivity coefficient of the patient's i-th pain within a day, used to adjust the pain severity according to the patient's pain location, and Sp ∈ [0.6, 1.2]. Specifically:

[0106] When the pain location is the limbs, it belongs to the category of surgical pain and can be relieved by massage, rest or physical therapy, and the sensitivity coefficient is set to 0.6;

[0107] When the pain location is the back and neck, although it does not endanger life, it seriously affects the quality of life, and the sensitivity coefficient is set to the moderate value of 0.8;

[0108] When the pain location is pelvic region pain, it is related to reproductive system, urinary system or skeletal problems, and the sensitivity coefficient is set to the moderate value of 0.9;

[0109] When the pain location is in the lungs, chest, or abdomen, it belongs to the category of internal medicine pain. The sensitivity coefficient is set to 1. At the same time, ultrasonic examinations (such as B-ultrasound, color Doppler ultrasound, etc.) are performed on the pain location to evaluate the severity of the pain location and provide timely treatment (because the above-mentioned category of internal medicine pain needs to be taken seriously, and the cause should be found in time to avoid the deterioration of the condition);

[0110] When the pain location is in the heart and head, the risk is the greatest, and the sensitivity coefficient is set to the highest value of 1.2. When there is heart pain, ultrasonic examinations (such as B-ultrasound, color Doppler ultrasound, etc.) are performed on the heart to evaluate the heart's morphology, movement, and blood flow conditions, and problems are detected and treated in a timely manner. When there is head pain, a CT examination is performed (because the heart and head are the most important parts of the human body, and the cause must be found and treated immediately when there is pain in the heart and head);

[0111] In the formula calculation:

[0112] This part reflects the increasing influence of high pain intensity Pi on the basic pain value Pd through a power function, so as to increase the basic pain value Pd calculated for the patient in severe pain;

[0113] This part performs a logarithmic process on the pain time Pct. As the pain time Pct increases, the basic pain value Pd will increase, but the growth rate will slow down, so as to ensure that while the pain time Pct has a positive impact on the calculated result of the basic pain value Pd, the excessive impact of long-term pain on the calculation of the basic pain value Pd can be reduced;

[0114] Multiply the intensity of the i-th pain taken to the power of 1.2 by This part of the influence term of the pain time Pct is then multiplied by the sensitivity coefficient Sp to obtain the pain value of the i-th time. Then, the multiple pain values within a day are added up and divided by the number of pain times N to obtain the average basic pain value Pd within a day.

[0115] In this embodiment:

[0116] Through the basic pain value algorithm unit, comprehensively considering the pain intensity Pi, pain duration Pct, pain frequency, and sensitivity coefficient Sp, the basic pain value Pd is calculated, providing a more comprehensive and detailed visual pain assessment. Compared with relying solely on the patient's subjective description or the doctor's simple scoring, this pain assessment method can more accurately reflect the patient's actual pain condition. Moreover, as a visible quantitative indicator, the basic pain value Pd helps standardize the pain assessment process. Different doctors or patients may have subjective differences when describing pain, while the calculation of the basic pain value Pd provides an objective measurement method, enabling effective comparison and analysis of the pain conditions of different patients or at different time points. The visual pain assessment report system can display the basic pain value Pd and its change trend of the same patient through a graphical interface to dynamically monitor the change of the patient's pain condition. This helps communication between doctors and patients, enabling patients to more intuitively understand their pain condition, and doctors can also use this data to explain treatment plans and expected effects to patients, which is of great significance for timely adjusting treatment plans, evaluating treatment effects, and predicting the pain development trend.

[0117] Please refer to Figures 1 to 2 , the comprehensive pain value algorithm unit is as follows:

[0118] ;

[0119] Where:

[0120] Ps represents the comprehensive pain value;

[0121] Pd represents the basic pain value;

[0122] HR represents the patient's heart rate, measured by an electrocardiogram monitor, and the healthy value is between 60 and 100;

[0123] SBP represents the patient's systolic blood pressure, measured by an electrocardiogram monitor, and the healthy value is between 90 and 139;

[0124] DBP represents the patient's diastolic blood pressure, measured by an electrocardiogram monitor, and the healthy value is between 60 and 89;

[0125] RR represents the patient's respiratory rate, measured by an electrocardiogram monitor, and the healthy value is between 12 and 22;

[0126] HRnorm represents the reference value of the heart rate healthy value, obtained by dividing the sum of the maximum value and the minimum value of the heart rate healthy value by 2, that is, (100 + 60) / 2 = 80;

[0127] SBPnorm represents the baseline value of the healthy systolic blood pressure, which is obtained by dividing the sum of the maximum value and the minimum value of the healthy systolic blood pressure by 2, that is, (139 + 90) / 2 = 114.5;

[0128] DBPnorm represents the baseline value of the healthy diastolic blood pressure, which is obtained by dividing the sum of the maximum value and the minimum value of the healthy diastolic blood pressure by 2, that is, (89 + 60) / 2 = 74.5;

[0129] RRnorm represents the baseline value of the healthy respiratory rate, which is obtained by dividing the sum of the maximum value and the minimum value of the healthy respiratory rate by 2, that is, (22 + 12) / 2 = 17;

[0130] α represents the correction factor, with a base value of 1, which is self-adjusted in the pain assessment reporting system;

[0131] In the formula calculation:

[0132] This part represents the influencing term of the patient's heart rate HR on the calculation of the comprehensive pain value Ps. The numerator part takes the absolute value after subtracting the baseline value HRnorm of the healthy heart rate from the patient's heart rate HR, representing the degree of deviation of the patient's heart rate HR from the healthy value. The constant 2 in the numerator part is regarded as dividing by 1 / 2 in the denominator part. This part is used as the denominator, which is half of the healthy heart rate range, that is, the maximum degree of deviation allowed for the heart rate HR up and down, representing the maximum degree of deviation allowed for the patient's heart rate HR. It is obtained by dividing the numerator by the denominator. This part normalizes the degree of deviation of the patient's heart rate HR from the healthy value to the range of 0 to 1. When the patient's heart rate HR is close to the baseline value HRnorm of the healthy heart rate, the influencing value of the patient's heart rate HR in this part tends to 0, indicating that the patient's heart rate HR will not affect the calculation of the comprehensive pain value Ps. As the degree of deviation of the patient's heart rate HR from the baseline value HRnorm of the healthy heart rate becomes larger, the numerator becomes larger, and the calculated comprehensive pain value Ps is higher.

[0133] The influencing ways of the patient's systolic blood pressure SBP, the patient's diastolic blood pressure DBP, and the patient's respiratory rate RR on the calculation of the comprehensive pain value Ps are the same as that of the patient's heart rate HR. After adding the influencing terms of these four indicators and multiplying by one-fourth, the comprehensive influencing term based on physiological indicators is obtained. After adding 1 to this part of the comprehensive influencing term and multiplying by the base pain value Pd, the comprehensive pain value Ps adjusted based on physiological indicators is obtained.

[0134] In this embodiment:

[0135] Traditional pain assessment mainly relies on the subjective descriptions of patients, which may be affected by various factors such as personal perception and expression ability. The comprehensive pain value algorithm unit comprehensively considers four physiological indicators of the patient's heart rate HR, systolic blood pressure SBP, diastolic blood pressure DBP, and respiratory rate RR, and combines with the basic pain value Pd to calculate the comprehensive pain value Ps, enabling medical staff to obtain a quantifiable and visualizable pain assessment index. This helps medical staff understand the patient's pain condition more accurately. By analyzing the comprehensive pain values Ps of patients in the assessment database at different time points and generating a visual report, doctors can more easily explain the patient's pain condition and treatment plan to the patient. The patient can also intuitively understand their own pain condition and treatment effect through the visual pain assessment report system, which helps enhance the patient's confidence in the treatment plan and promotes communication between doctors and patients, strengthening the patient's trust in the doctor.

[0136] And since the calculation of the comprehensive pain value Ps involves the patient's real-time physiological data (such as heart rate, blood pressure, respiratory rate, etc.), the pain assessment report system can monitor the patient's pain condition in real time. When the patient's pain condition changes rapidly, the system can quickly respond and provide a warning to medical staff so that the treatment plan can be adjusted in time. For example, for patients with more severe pain, the dose of analgesic drugs can be increased or more effective drugs can be replaced, providing scientific and reliable data support for medical staff in treating the patient's pain.

[0137] Please refer to Figures 1 to 2 , the planned drug dosage algorithm unit is as follows:

[0138] ;

[0139] Where:

[0140] Dp represents the planned drug dosage, which is the planned dose of painkillers applied to the patient;

[0141] Db represents the basic drug dosage, which is the basic dose of painkillers taken by the patient;

[0142] We represents the patient's weight, which is obtained from the hospital information system;

[0143] Age represents the patient's age, which is obtained from the hospital information system;

[0144] Sa represents the gender adjustment factor. According to the different pain sensitivities and tolerances of men and women, it is 1.1 for women and 0.9 for men;

[0145] Ps represents the comprehensive pain value, which is calculated by the comprehensive pain value algorithm unit;

[0146] In the formula calculation:

[0147] This part represents the influencing term of the patient's weight We on the calculated planned drug dosage Dp. The volume of drug distribution is related to weight. The greater the weight, the higher the dose required to achieve the same blood drug concentration. Dividing the patient's weight by the standard weight of 70 reflects the linear influence of the patient's weight We on the calculated planned drug dosage Dp. As the patient's weight We increases, the calculated planned drug dosage Dp increases;

[0148] This part represents the influencing term of the patient's age Age on the calculated planned drug dosage Dp. The older the age, the lower the metabolic capacity of the elderly, the lower the drug clearance rate, and the easier it is to accumulate and cause poisoning. The dose of painkillers is appropriately reduced. Specifically: when the patient's age Age ≥ 30, based on 30 years old, the dose is reduced by 0.5% for each additional year. When the patient's age Age is less than 30, take the minimum value of the patient's age Age, which is 30, at this time The value of this part is 1, representing young and middle-aged patients under 30 years old, and age will not affect the calculation of the planned drug dosage Dp;

[0149] This part represents the influencing term of the patient's pain on the planned drug dosage Dp. Since the value range of the hyperbolic tangent function tanh is (-1, 1), after adding 1, The value range of this part is (0, 2), and the constant 5 is the pain good threshold of the comprehensive pain value Ps. Specifically:

[0150] When the comprehensive pain value Ps is greater than 5, as the comprehensive pain value Ps increases, the value of this part of the tangent function tanh approaches 1, representing that as the patient's comprehensive pain value Ps increases, the required drug dosage is twice the basic drug dosage Db;

[0151] When the comprehensive pain value Ps is less than 5, as the comprehensive pain value Ps decreases, the value of this part of the tangent function tanh approaches -1, The calculated value approaches 0, representing that as the patient's comprehensive pain value Ps continues to decrease below the pain good threshold, the patient's recovery is better, and the painkiller dosage is close to 0, avoiding the negative effects on the patient's body caused by excessive medication.

[0152] In this embodiment:

[0153] The physiological condition, pain perception, and drug response of each patient are unique. The planned drug dosage algorithm unit comprehensively considers multiple influencing factors such as the basic drug dosage Db, patient weight We, patient age Age, and comprehensive pain value Ps, and can calculate a more accurate planned drug dosage Dp, which can better meet the specific needs of each patient. This helps to ensure that patients receive the right amount of drug treatment, avoid under-dosage or over-dosage situations, thereby improving the treatment effect and reducing the risk of adverse reactions. Since the pain condition and physiological indicators (heart rate, blood pressure, etc.) of patients will change with the treatment process, it is necessary to adjust the drug dosage in a timely manner. The planned drug dosage algorithm unit can monitor these data in real time and dynamically adjust the planned drug dosage Dp according to the actual situation to ensure the continuous effectiveness of the treatment. Traditional drug dosage adjustment often relies on doctors' experience and judgment. By displaying the calculation process and results of the planned drug dosage Dp through a visual pain assessment report system, the communication between doctors and patients can be enhanced, enabling patients to better understand their treatment plan and medication basis.

[0154] In summary, the present application provides a more scientific and efficient automated calculation method. Doctors can quickly formulate a reasonable treatment plan based on the pain condition and physiological indicators (heart rate, blood pressure, etc.) of patients, improving medical efficiency and reducing the workload of doctors.

[0155] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

3. A visual pain assessment and reporting system according to claim 1, characterized in that: The calculation and processing module includes a basic pain value algorithm unit, a comprehensive pain value algorithm unit, a planned medication dosage algorithm unit and a feedback adjustment unit.

4. A visual pain assessment and reporting system according to claim 3, characterized in that: The basic pain value algorithm unit is as follows: ； in: Pd represents the basic pain value; Pi represents pain intensity, which is the intensity of the patient's i-th pain in a day; Pct represents the pain time, which is the time of the patient's i-th pain in a day; N stands for pain number, which is the number of pain episodes a patient has in a day; Sp represents the sensitivity coefficient, which is the sensitivity coefficient of the patient's i-th pain in a day and is used to adjust the severity of pain according to the patient's pain location, Sp∈[0.6,1.2]; In the calculation formula: This part reflects the aggravation of the impact of high pain intensity Pi on the basic pain value Pd through a power function, increasing the basic pain value Pd calculated by the patient when the pain is severe; This part performs logarithmic processing on the pain time Pct. As the pain time Pct increases, the basic pain value Pd will increase, but the growth rate will slow down. This ensures that the pain time Pct has a positive impact on the basic pain value Pd, while reducing the excessive impact of long-term pain on the calculation of the basic pain value Pd. Take the intensity of the i-th pain and multiply it by 1.2 The influencing term of this part of the pain time Pct is multiplied by the sensitivity coefficient Sp to obtain the i-th pain value. The multiple pain values ​​within a day are added together and divided by the number of pain times N to obtain the basic pain value Pd after averaging within a day.

5. A visual pain assessment and reporting system according to claim 4, characterized in that: The comprehensive pain value algorithm unit is as follows: ； in: Ps represents the comprehensive pain value; Pd represents the basic pain value; HR represents the patient's heart rate; SBP represents the patient’s systolic blood pressure; DBP represents the patient’s diastolic blood pressure; RR represents the patient's respiratory rate; HRnorm represents the baseline value of heart rate health; SBPnorm represents the baseline value of systolic blood pressure health value; DBPnorm represents the baseline value of diastolic blood pressure health value; RRnorm represents the baseline value of healthy respiratory rate; α represents the correction factor, with a base value of 1, which is self-adjusted in the pain assessment and reporting system; In the calculation formula: This part represents the influence of the patient's heart rate HR on the calculation of the comprehensive pain value Ps. The numerator is the absolute value of the patient's heart rate HR minus the baseline value HRnorm of the heart rate health value, which represents the degree of deviation of the patient's heart rate HR from the health value. The constant 2 in the numerator is regarded as the denominator divided by 1 / 2. This part is used as the denominator, representing the maximum deviation allowed for the patient's heart rate HR, and is obtained by dividing the numerator by the denominator. In this part, the deviation of the patient's heart rate HR from the healthy value is standardized to a range of 0 to 1. When the patient's heart rate HR is close to the baseline value HRnorm of the heart rate health value, the impact value of the patient's heart rate HR in this part tends to 0, which means that the patient's heart rate HR will not affect the calculation of the comprehensive pain value Ps. As the patient's heart rate HR deviates further from the baseline value HRnorm of the heart rate health value, the larger the numerator, the higher the calculated comprehensive pain value Ps; The influence of the patient's systolic blood pressure SBP, the patient's diastolic blood pressure DBP and the patient's respiratory rate RR on the calculation of the comprehensive pain value Ps is the same as the influence of the patient's heart rate HR. The influencing items of these four indicators are added and multiplied by one quarter to obtain a comprehensive influencing item based on physiological indicators. This part of the comprehensive influencing item is added by 1 and multiplied by the basic pain value Pd to obtain the comprehensive pain value Ps adjusted based on physiological indicators.

6. A visual pain assessment and reporting system according to claim 5, characterized in that: The planned application amount algorithm unit is as follows: ； in: Dp represents the planned application amount; Db represents the basic application rate; We represents the patient's weight; Age represents the patient's age; Sa represents the sex adjustment factor; Ps represents the comprehensive pain value; In the calculation formula: This part represents the influence of the patient's weight We on the calculated planned dosage Dp. The patient's weight divided by the standard weight 70 reflects the linear influence of the patient's weight We on the calculated planned dosage Dp. As the patient's weight We increases, the calculated planned dosage Dp increases. This part represents the influence of the patient's age on the calculated planned dosage Dp. Specifically: For patients aged ≥ 30, the dose is reduced by 0.5% for every additional year of age. When the patient's age is less than 30, the minimum value of the patient's age, 30, is taken. The value of this part is 1, which represents young and middle-aged patients under 30 years old. Age will not affect the calculation of the planned dosage Dp; This part represents the influence of the patient's pain on the planned dosage Dp. The value range of the hyperbolic tangent function tanh is (-1,1). After adding 1, The value range of this part is (0,2), and the constant 5 is the pain threshold of the comprehensive pain value Ps. Specifically: When the comprehensive pain value Ps is greater than 5, as the comprehensive pain value Ps increases, the value of the tangent function tanh approaches 1, which means that as the patient's comprehensive pain value Ps increases, the required dosage is twice the basic dosage Db; When the comprehensive pain value Ps is less than 5, as the comprehensive pain value Ps decreases, the value of the tangent function tanh approaches -1. The calculated value of approaches 0, which means that as the patient's comprehensive pain value Ps continues to decrease below the good pain threshold, the patient's recovery is better and the amount of analgesic administered is close to 0.
