Description

Technical Field

[0001] The invention belongs to the technical field of radial artery compression hemostat, and in particular relates to an intelligent control system and method for a radial artery compression hemostat. Background Art

[0002] The radial artery compression hemostat plays a vital role in the diagnosis and treatment of cardiovascular diseases, especially after coronary angiography, percutaneous coronary intervention and other surgeries. It can effectively control bleeding and significantly reduce the risk of complications, thereby improving the success rate of surgery and accelerating the patient's recovery process. However, in actual clinical applications, traditional radial artery compression hemostat often faces challenges such as cumbersome operation, large fluctuations in hemostatic effects, and poor patient comfort. In order to achieve more accurate and stable hemostatic effects, intelligent control of the radial artery compression hemostat is essential.

[0003] In the prior art, there are also some solutions related to the control of radial artery compression hemostat. For example, Chinese Patent Publication No. CN115670572A is a radial artery intelligent compression hemostat and its control method. The systolic and diastolic blood pressure values ​​of the patient are measured before the operation. After the operation, the radial artery intelligent compression hemostat is tied to the patient's wrist with a strap, and the center position of the compression pad is against the radial artery puncture point. The reduction motor drives the compression rod, the pressure plate and the compression pad to move close to the radial artery puncture point in sequence, so that the compression pad applies pressure to the skin at the puncture site. The pressure can be converted into pressure intensity accordingly. The high-pressure compression time, the high-pressure pressure relief time, the compression time of each stage and the total compression time are set to perform related hemostasis operations, which can avoid long-term compression ischemia at the distal end and avoid bleeding caused by insufficient pressure, so as to achieve the purpose of radial artery compression hemostasis as quickly as possible and reduce secondary injuries and sequelae after compression.

[0004] Another Chinese patent publication number CN115054311A is an intelligent decompression control method for a radial artery compression hemostat. The wearing device of the radial artery compression hemostat is suitable for binding to the human body. The compression device is arranged on the wearing device. The compression device compresses the corresponding human artery. The electronic control component is connected to the compression device to control the action of the compression device. The deflation device arranged in the electronic control component is a peristaltic deflation pump. The radial artery compression hemostat detects the systolic blood pressure of the human body, and adds a pressure value P as the starting pressure P1 on the basis of the systolic blood pressure, and then decompresses the blood pressure successively, and each decompression value is the rounded P1 / 15 mmHg, until the decompression is completed. It can realize precise control of the air pressure of the radial artery compression hemostat, and fully intelligent control of pressurization and decompression can not only effectively reduce the waste of manpower costs, but also improve the working stability and reliability of the equipment.

[0005] Although the above schemes propose some solutions related to the control of radial artery compression hemostat, the prior art still has the following limitations. Specifically, the prior art lacks the ability to highly personalized control of radial artery compression hemostat.

[0006] On the one hand, the initial pressure setting of the existing radial artery compression hemostat for the patient is mostly based on the patient's systolic blood pressure obtained by wearing monitoring, and simply superimposed with the industry's commonly used preset pressure safety margin range, seriously ignoring the specific differences in puncture surgery for different patients and the patients' own physiological characteristics, resulting in the inability to accurately determine the effective adaptation initial pressure that meets the patient's actual needs, which greatly affects the hemostatic effect.

[0007] On the other hand, the existing radial artery compression hemostat is designed to decompress patients. A single decompression operation often mechanically follows the preset decompression amount without fully considering the actual performance during the decompression process. This makes it difficult to flexibly adjust the decompression strategy, which may increase the chance of complications. Summary of the invention

[0008] In view of this, in order to solve the problems raised in the above background technology, an intelligent control system and method for a radial artery compression hemostat is now proposed.

If not, the initial pressure is continuously corrected and adapted until the initial hemostatic effect meets expectations. The optimal distribution weights corresponding to the historical reference initial pressure and the individual reference initial pressure are reversely analyzed and uploaded to the cloud database simultaneously.

[0014] The decompression operation module is used to monitor the hemostasis status of the target patient in real time and determine whether the preset decompression decision conditions are met, so as to perform the decompression operation of the radial artery compression hemostat and dynamically adjust the decompression amount of each decompression operation according to the preset decompression interval duration until the radial artery compression hemostat reaches a pressure balance state and stops the decompression operation.

[0015] The decompression operation rationality evaluation module is used to collect the overall decompression operation performance data of the radial artery compression hemostat on the target patient, evaluate and provide feedback on the rationality of the decompression operation of the radial artery compression hemostat on the target patient.

[0016] The wearing release prompt module is used to wait for the pressure balance state of the radial artery compression hemostat to continue for a preset time and then execute the wearing release prompt operation of the radial artery compression hemostat.

[0017] In a second aspect, the present invention provides an intelligent control method for a radial artery compression hemostat, comprising: S1. recording a patient currently wearing a radial artery compression hemostat as a target patient, retrieving puncture surgery information and physiological monitoring information of the target patient, and analyzing the individual reference initial pressure and historical reference initial pressure of the radial artery compression hemostat for the target patient.

[0018] S2. Weights are assigned to the historical reference initial pressure and the individual reference initial pressure to determine the adapted initial pressure of the radial artery compression hemostat for the target patient, thereby performing the pressure application operation of the radial artery compression hemostat.

[0019] S3. Evaluate the initial hemostatic effect of the radial artery compression hemostat on the target patient and determine whether it meets expectations. If not, continue to modify and adapt the initial pressure until the initial hemostatic effect meets expectations. Reversely analyze the optimal allocation weights corresponding to the historical reference initial pressure and the individual reference initial pressure at this time, and upload them to the WEB cloud simultaneously.

[0020] S4. Monitor the hemostasis status of the target patient in real time to determine whether the preset decompression decision conditions are met, and execute the decompression operation of the radial artery compression hemostat. Dynamically adjust the decompression amount of each decompression operation according to the preset decompression interval duration until the radial artery compression hemostat reaches a pressure balance state and stops the decompression operation.

[0021] S5. Collect the overall decompression performance data of the radial artery compression hemostat for the target patients, evaluate and provide feedback on the rationality of the decompression operation of the radial artery compression hemostat for the target patients.

[0022] S6. After the pressure balance state of the radial artery compression hemostat is maintained for a preset period of time, the radial artery compression hemostat wearing prompt removal operation is performed.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 As shown, the first aspect of the present invention provides an intelligent control system for a radial artery compression hemostat, including: a reference initial pressure analysis module, a pressure operation module, an initial hemostasis effect evaluation module, a decompression operation module, a decompression operation rationality evaluation module and a wearing release prompt module.

[0034] The reference initial pressure analysis module is connected to the pressure operation module, the pressure operation module is connected to the initial hemostasis effect evaluation module, the initial hemostasis effect evaluation module is connected to the decompression operation module, the decompression operation module is connected to the decompression operation rationality evaluation module, and the decompression operation rationality evaluation module is connected to the wearing release prompt module.

[0035] The reference initial pressure analysis module is used to record the patient currently wearing the radial artery compression hemostat as the target patient, retrieve the puncture surgery information and physiological monitoring information of the target patient, and analyze the individual reference initial pressure and historical reference initial pressure of the radial artery compression hemostat for the target patient.

[0036] Specifically, the puncture operation information includes the maximum outer diameter value of the puncture needle, the number of punctures and the maximum puncture angle.

[0037] The physiological monitoring information includes systolic blood pressure, diastolic blood pressure, values ​​of various coagulation function indexes and values ​​of various vascular elasticity indexes.

[0038] It should be noted that the puncture surgery information and physiological monitoring information of the above-mentioned target patients are mainly retrieved through the shared authorized medical archive information system.

[0039] The above-mentioned coagulation function indicators include but are not limited to fibrinogen, activated partial thromboplastin time, prothrombin time, etc., and the vascular elasticity indicators include but are not limited to pulse wave velocity, ankle-brachial index, radial artery wall thickening value, etc.

[0040] Reference Figure 3 As shown, specifically, the specific analysis process of the reference initial pressure analysis module includes: according to the puncture needle outer diameter range, puncture number range and puncture angle range recorded by the puncture surgery operation stored in the cloud database, the maximum outer diameter value of the puncture needle, the number of punctures and the maximum puncture angle in the puncture surgery information of the target patient are standardized, and the accumulated values ​​are inserted into the natural exponential function to obtain the hemostasis difficulty correlation coefficient of the target patient under the influence of surgical puncture.

[0041] It should be noted that the specific process of standardizing the maximum outer diameter value of the puncture needle, the number of punctures and the maximum puncture angle in the puncture surgery information of the target patient is as follows: extract the upper and lower limits of the outer diameter interval of the puncture needle recorded in the puncture surgery operation, use the calculated difference between the maximum outer diameter value of the puncture needle in the puncture surgery information of the target patient and the lower limit of the outer diameter interval of the puncture needle recorded in the puncture surgery operation as the numerator, and use the calculated difference between the upper and lower limits of the outer diameter interval of the puncture needle recorded in the puncture surgery operation as the denominator, carry out ratio analysis, and use the ratio analysis result as the standardized value of the maximum outer diameter value of the puncture needle in the puncture surgery information of the target patient. Similarly, the number of punctures and the maximum puncture angle in the puncture surgery information of the target patient are standardized.

[0042] According to the preset reasonable numerical ranges of diastolic blood pressure, various coagulation function indicators and various vascular elasticity indicators corresponding to the normal physiological state of the human body stored in the cloud database, the abnormal expression degrees corresponding to the diastolic blood pressure, various coagulation function indicators and various vascular elasticity indicators of the target patient are calculated, and the accumulated results are inserted into the natural exponential function to obtain the hemostatic disorder coefficient of the target patient under the influence of the physiological state.

[0043] It should be noted that the specific calculation process of the abnormal expression degree corresponding to the diastolic blood pressure, various coagulation function indicators, and various vascular elasticity indicators of the above-mentioned target patients is: compare the diastolic blood pressure of the target patient with the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body; if the diastolic blood pressure of the target patient is within the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, then the abnormal expression degree corresponding to the diastolic blood pressure of the target patient is set to 0; if the diastolic blood pressure of the target patient is less than the lower limit of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, then the absolute difference between the diastolic blood pressure of the target patient and the lower limit of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body is calculated. , further perform a ratio analysis with the lower limit of the preset reasonable numerical range of diastolic blood pressure corresponding to the normal physiological state of the human body, so as to obtain the abnormal expression degree corresponding to the diastolic blood pressure of the target patient; if the diastolic blood pressure of the target patient is greater than the upper limit of the preset reasonable numerical range of diastolic blood pressure corresponding to the normal physiological state of the human body, then the difference between the diastolic blood pressure of the target patient and the upper limit of the preset reasonable numerical range of diastolic blood pressure corresponding to the normal physiological state of the human body is further performed a ratio analysis with the upper limit of the preset reasonable numerical range of diastolic blood pressure corresponding to the normal physiological state of the human body, so as to obtain the abnormal expression degree corresponding to the diastolic blood pressure of the target patient; similarly, calculate the abnormal expression degrees corresponding to each coagulation function index and each vascular elasticity index of the target patient.

[0044] The cumulative value of the hemostasis difficulty correlation coefficient and the body's hemostasis disorder coefficient is used as the comprehensive hemostasis evaluation factor, which is multiplied by the preset hemostasis pressure value corresponding to the unit comprehensive hemostasis evaluation factor stored in the cloud database. The product operation result after rounding up is added to the systolic blood pressure of the target patient to obtain the individual reference initial pressure of the radial artery compression hemostat for the target patient.

[0045] Specifically, the specific analysis process of the reference initial pressure analysis module also includes: extracting the uploaded content of the pressure application operation of each patient who has historically worn a radial artery compression hemostat stored in the cloud database, including the hemostasis difficulty correlation coefficient, the body hemostasis disorder coefficient, the optimal allocation weight of the adaptive initial pressure corresponding to the effective hemostasis and its corresponding historical reference initial pressure and the individual reference initial pressure, comparing the hemostasis difficulty correlation coefficient and the body hemostasis disorder coefficient of each patient who has historically worn a radial artery compression hemostat with the target patient, and screening out the patients who have historically worn a radial artery compression hemostat with a high similarity to the current wearing condition of the target patient, and recording them as the historical reference patients.

[0046] It should be noted that the specific screening process of the above-mentioned historical reference patients is as follows: the absolute difference between the hemostatic difficulty correlation coefficient of each historical patient wearing radial artery compression hemostat and the hemostatic difficulty correlation coefficient of the target patient is calculated, and the ratio analysis is performed with the hemostatic difficulty correlation coefficient of the target patient to obtain the deviation ratio of the hemostatic difficulty correlation coefficient of each historical patient wearing radial artery compression hemostat and the target patient. Similarly, the deviation ratio of the body hemostatic disorder coefficient of each historical patient wearing radial artery compression hemostat and the target patient is calculated, the deviation ratio of the hemostatic difficulty correlation coefficient and the body hemostatic disorder coefficient deviation ratio are accumulated, and the negative value of the accumulated value is substituted into the natural exponential function to obtain the similarity evaluation index, thereby obtaining the similarity evaluation index of each historical patient wearing radial artery compression hemostat and the target patient. If the similarity evaluation index of a historical patient wearing radial artery compression hemostat and the target patient is greater than the preset similarity evaluation index reaching threshold, it means that the historical patient wearing radial artery compression hemostat and the current wearing status of the target patient are highly similar, and the historical patient wearing radial artery compression hemostat is recorded as a historical reference patient, thereby screening the historical reference patients.

[0047] The average of the adapted initial pressure corresponding to the effective hemostasis of each historical reference patient is calculated to obtain the historical reference initial pressure of the radial artery compression hemostat for the target patient.

[0048] The embodiment of the present invention retrieves the puncture surgery information and physiological monitoring information of the target patient, and conducts individual reference initial pressure analysis and historical reference initial pressure analysis of the radial artery compression hemostat for the target patient from the perspective of the target patient's individual medical performance and historical experience, assists in customized initial pressure setting for the target patient, and provides a scientific basis for the use of the radial artery compression hemostat.

[0049] The pressure operation module is used to weight the historical reference initial pressure and the individual reference initial pressure, determine the adapted initial pressure of the radial artery compression hemostat for the target patient, and perform the pressure operation of the radial artery compression hemostat.

[0050] Specifically, the specific analysis of the pressure operation module includes: determining the initial pressure safety interval of the target patient according to the reserved safety pressure interval corresponding to the initial pressure setting of the radial artery compression hemostat stored in the cloud database and the systolic blood pressure of the target patient.

[0051] It should be noted that the upper limit value of the above-mentioned target patient's initial pressure safety range is the cumulative value of the target patient's systolic pressure and the upper limit value of the reserved safety pressure range corresponding to the initial pressure setting of the radial artery compression hemostat, and the lower limit value of the target patient's initial pressure safety range is the cumulative value of the target patient's systolic pressure and the lower limit value of the reserved safety pressure range corresponding to the initial pressure setting of the radial artery compression hemostat.

[0052] The optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure corresponding to the adaptive initial pressure for effective hemostasis of each patient wearing the radial artery compression hemostat are extracted, each historical weight allocation reference combination is constructed, the relative prevalence of each historical weight allocation reference combination is calculated, and the historical weight allocation reference combination with the largest relative prevalence is screened, and the historical reference initial pressure and the individual reference initial pressure are weighted according to the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure corresponding to the adaptive initial pressure for effective hemostasis of each patient wearing the radial artery compression hemostat. The historical reference initial pressure and the individual reference initial pressure of the radial artery compression hemostat for the target patient are respectively accumulated with the product of their corresponding allocation weights to obtain the reasonable reference initial pressure of the radial artery compression hemostat for the target patient, and the adaptive initial pressure of the radial artery compression hemostat for the target patient is determined according to the comparison relationship relative to the safety interval of the initial pressure of the target patient.

[0053] It should be noted that the above-mentioned historical weight distribution reference combinations are mutually corresponding to the patients who have historically worn radial artery compression hemostat, that is, each historical weight distribution reference combination contains the optimal distribution weights of the adaptive initial pressure for effective hemostasis of the corresponding patients who have historically worn radial artery compression hemostat, the historical reference initial pressure and the individual reference initial pressure.

[0054] The specific calculation process of the relative prevalence of the above-mentioned historical weight allocation reference combinations is as follows: extract a historical weight allocation reference combination, analyze the deviation measurement index between the historical weight allocation reference combination and other historical weight allocation reference combinations through the Euclidean distance calculation formula, if the deviation measurement index of the two historical weight allocation reference combinations is less than or equal to the preset deviation measurement index permission threshold, it means that the two historical weight allocation reference combinations are similar item combinations to each other, thereby counting the number of similar item combinations of the historical weight allocation reference combination, and taking the ratio of the similar item combination to the total number of historical weight allocation reference combinations as the relative prevalence of the historical weight allocation reference combination, and similarly calculating and obtaining the relative prevalence of each historical weight allocation reference combination.

[0055] It should also be noted that the specific process of determining the adapted initial pressure of the radial artery compression hemostat for the target patient is as follows: if the reasonable reference initial pressure of the radial artery compression hemostat for the target patient is within the target patient's initial pressure safety interval, the reasonable reference initial pressure of the radial artery compression hemostat for the target patient is determined as the adapted initial pressure of the radial artery compression hemostat for the target patient; if the reasonable reference initial pressure of the radial artery compression hemostat for the target patient is greater than the upper limit value of the target patient's initial pressure safety interval, the upper limit value of the target patient's initial pressure safety interval is determined as the adapted initial pressure of the radial artery compression hemostat for the target patient; if the reasonable reference initial pressure of the radial artery compression hemostat for the target patient is less than the lower limit value of the target patient's initial pressure safety interval, the lower limit value of the target patient's initial pressure safety interval is determined as the adapted initial pressure of the radial artery compression hemostat for the target patient.

[0056] The embodiment of the present invention weights the historical reference initial pressure and the individual reference initial pressure, and determines the adaptive initial pressure of the radial artery compression hemostat for the target patient within the target patient's initial pressure safety range, thereby greatly reducing the possibility of risks to the patient due to improper pressure setting, thereby ensuring the safety of the patient.

[0057] The initial hemostatic effect evaluation module is used to evaluate the initial hemostatic effect of the radial artery compression hemostat on the target patient and determine whether it meets expectations. If not, the initial pressure is continuously corrected and adapted until the initial hemostatic effect meets expectations. The optimal allocation weights corresponding to the historical reference initial pressure and the individual reference initial pressure are reversely analyzed and uploaded to the cloud database simultaneously.

[0058] Specifically, the specific analysis process of the initial hemostasis effect evaluation module includes: collecting the effective hemostasis index values ​​of the target patient's puncture position within a preset time period , cumulative bleeding volume and swelling rate ,in , 1 means that the puncture site has effectively stopped bleeding, and 0 means that the puncture site has not effectively stopped bleeding. According to the formula Analyze the evaluation indicators of the initial hemostatic effect of radial artery compression hemostat on target patients. They are respectively the preset reference cumulative bleeding volume and swelling rate.

[0059] If the initial hemostatic effect evaluation index of the radial artery compression hemostat for the target patient is greater than the preset threshold value of the hemostatic effect evaluation index, it is judged that the initial hemostatic effect has reached the expectation; otherwise, it is judged that the initial hemostatic effect has not reached the expectation.

[0060] When it is judged that the initial hemostatic effect does not meet expectations, the absolute difference between the initial hemostatic effect evaluation index and its preset threshold value is obtained, and the absolute difference is multiplied by the preset corrected initial pressure corresponding to the unit initial hemostatic effect evaluation index stored in the cloud database to correct the adaptive initial pressure. After the next preset time, the above process is repeated until it is judged that the initial hemostatic effect meets expectations.

[0061] It should be noted that the specific process of the above reverse analysis of the optimal allocation weights corresponding to the historical reference initial pressure and the individual reference initial pressure at this time is: obtaining the adaptive initial pressure corresponding to when the initial hemostatic effect of the radial artery compression hemostat for the target patient reaches the expected level, setting the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure to satisfy the constraint condition that the cumulative value is 1, thereby generating a series of test groups, which include the test allocation weights corresponding to the historical reference initial pressure and the individual reference initial pressure.

[0062] The historical reference initial pressure and individual reference initial pressure of the radial artery compression hemostat for the target patient are accumulated with the product of the test allocation weights set for each test group, respectively, to obtain the reasonable reference initial pressure of the radial artery compression hemostat for the target patient calculated for each test group, and the absolute value is subtracted from the adapted initial pressure corresponding to the initial hemostatic effect of the radial artery compression hemostat for the target patient when the expected effect is achieved, and the test allocation weights of the historical reference initial pressure and the individual reference initial pressure set for the test group with the smallest absolute difference are selected to determine the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure.

[0063] The embodiment of the present invention continuously corrects and adapts the initial pressure until the initial hemostatic effect of the radial artery compression hemostat on the target patient reaches the expected level, reversely analyzes the optimal allocation weights corresponding to the historical reference initial pressure and the individual reference initial pressure at this time and uploads them synchronously, providing data support for subsequent patients wearing the radial artery compression hemostat, thereby achieving continuous and precise optimization of the initial pressure setting for patients wearing the radial artery compression hemostat.

[0064] The decompression operation module is used to monitor the hemostasis status of the target patient in real time, determine whether the preset decompression decision conditions are met, and thereby perform the decompression operation of the radial artery compression hemostat, and dynamically adjust the decompression amount of each decompression operation according to the preset decompression interval duration until the radial artery compression hemostat reaches a pressure balance state and stops the decompression operation.

[0065] Specifically, the specific analysis process of the decompression operation module includes: after it is determined that the initial hemostatic effect has reached the expected result, the target user's hemostatic demand and blood perfusion demand are analyzed in real time; when the difference between the hemostatic demand and the blood perfusion demand is less than or equal to a preset value, it is determined that the current target patient's hemostatic condition has reached the preset decompression decision condition.

[0066] It should be noted that the specific process of the above-mentioned real-time analysis of the target user's hemostatic demand and blood perfusion demand is as follows: starting from the time point when the initial hemostatic effect is judged to have reached the expected value, the effective hemostatic index value, cumulative bleeding volume and swelling rate of the puncture position of the target patient are continuously collected, which is consistent with the analysis method of the initial hemostatic effect evaluation index of the radial artery compression hemostat for the target patient, and the hemostatic effect evaluation index of the radial artery compression hemostat for the target patient at each unit time point after the time point when the initial hemostatic effect reaches the expected value is obtained. If it is greater than or equal to the preset standard threshold of the hemostatic effect evaluation index, then the interval time relative to the time point when the initial hemostatic effect is judged to have reached the expected value is obtained, and a ratio analysis is performed with the preset reference interval time, and the negative value of the ratio analysis result is substituted into the natural exponential function to obtain the hemostatic demand of the target user at the corresponding unit time point. If it is less than the preset standard threshold of the hemostatic effect evaluation index, the hemostatic demand of the target user at the corresponding unit time point is directly set to 1.

[0067] From the time point when the initial hemostasis effect reaches the expected time point, the target patient's blood oxygen saturation and heart rate values ​​are collected in real time to obtain the relative increase in the target patient's heart rate at each unit time point after the initial hemostasis effect reaches the expected time point and the relative decrease in blood oxygen , is the number of each unit time point, , according to the formula Calculate the blood perfusion requirement of the target patient at each unit time point after the initial hemostasis effect reaches the expected time point, They are respectively the preset allowable heart rate increase amplitude and the preset allowable blood oxygen decrease amplitude.

[0068] The decompression amount of the initial decompression operation is set as the preset decompression amount, and the degree of weakening of the hemostatic effect and the degree of improvement of blood flow embolism of the target patient within the preset decompression interval corresponding to the initial decompression operation are monitored. The cumulative value of the product of the weakening of the hemostatic effect and the degree of improvement of the blood flow embolism with their corresponding preset weights is calculated. , determine the decompression adjustment coefficient for the next decompression operation and multiply it by the preset decompression amount as the corresponding decompression amount for the next decompression operation, and repeat the above process to achieve dynamic regulation of the decompression amount for each decompression operation.

[0069] It should be noted that the degree of weakening of hemostatic effect and improvement of blood flow embolism of the target patient within the preset decompression interval corresponding to the above-mentioned initial decompression operation are both based on the preset decompression operation scoring standards of the cloud database, and the specific amount of additional bleeding and increase in blood flow velocity of the target patient within the preset decompression interval corresponding to the initial decompression operation are collected for corresponding evaluation.

[0070] It should also be noted that the specific process of determining the decompression adjustment coefficient for the next decompression operation is as follows: extracting the execution operation threshold value of the preset decompression operation scoring standard content specification ,when , it means that the hemostatic effect is weakened to a relatively low degree and the improvement of blood flow embolism is relatively low, and the decompression adjustment coefficient for the next decompression operation is determined to be 0.8.

[0071] when , it means that the hemostatic effect is relatively weakened and the blood flow embolism is relatively improved, and the decompression adjustment coefficient for the next decompression operation is determined to be 1.2.

[0072] when , it means that the hemostatic effect is weakened to a relatively low degree or the improvement of blood flow embolism is relatively low, and the decompression adjustment coefficient for the next decompression operation is determined to be 1.

[0073] The embodiment of the present invention monitors the hemostasis status of the target patient in real time to determine whether the preset decompression decision conditions are met, and dynamically adjusts the decompression amount of each decompression operation according to the preset decompression interval duration to perform the decompression operation of the radial artery compression hemostat, which significantly improves the safety and effectiveness of the use of the radial artery compression hemostat, and is of great significance for improving the quality of patient care and promoting the development of personalized medicine.

[0074] The decompression operation rationality evaluation module is used to collect the overall decompression operation performance data of the radial artery compression hemostat on the target patient, evaluate and provide feedback on the rationality of the decompression operation of the radial artery compression hemostat on the target patient.

[0075] The specific analysis process of the reasonable decompression operation evaluation module includes: collecting the overall decompression operation performance data of the radial artery compression hemostat for the target patient, including the degree of weakening of the hemostatic effect of each decompression operation on the target patient within the preset decompression interval time. and improvement of thromboembolism , is the number of each decompression operation, , according to the formula , The hemostasis maintenance level coefficient and thrombosis improvement level coefficient of the target patient during the overall decompression operation were calculated respectively.
