Description

Technical Field

[0001] The present invention belongs to the technical field of radial artery compression hemostatic devices, and particularly relates to an intelligent control system and method for a radial artery compression hemostatic device. Background Technique

[0002] Radial artery compression hemostatic devices play a crucial role in the field of cardiovascular disease diagnosis and treatment, especially after surgeries such as coronary angiography and percutaneous coronary intervention. They can effectively control bleeding, significantly reduce the risk of complications, thereby improving the success rate of surgeries and accelerating the patient's recovery process. However, in actual clinical applications, traditional radial artery compression hemostatic devices often face challenges such as cumbersome operations, large fluctuations in hemostatic effects, and poor patient comfort. To achieve more precise and stable hemostatic effects, intelligent control of radial artery compression hemostatic devices is crucial.

[0003] In the prior art, there are also some solutions related to the control of radial artery compression hemostatic devices. For example, a radial artery intelligent compression hemostatic device and its control method with the Chinese patent publication number CN115670572A. By measuring the patient's systolic blood pressure value and diastolic blood pressure value before surgery, after the operation, the radial artery intelligent compression hemostatic device is strapped to the patient's wrist with a strap, and the center position of the compression pad is pressed against the upper part of the radial artery puncture point. The reduction motor drives the compression rod, the pressing plate, and the compression pad to move closer 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 correspondingly converted into pressure. Set the high-pressure compression time, high-pressure pressure relief time, compression time for each stage, and total compression time for relevant hemostatic operations, which can avoid long-term compression and ischemia at the distal end of the heart, and also avoid bleeding due to insufficient pressure, and achieve the purpose of radial artery compression hemostasis fastest, reducing secondary injuries and sequelae after compression.

[0004] Another intelligent decompression control method for a radial artery compression hemostatic device with the Chinese patent publication number CN115054311A. The wearing device of the radial artery compression hemostatic device is adapted to be bound to the human body, the compression device is arranged on the wearing device, the compression device corresponds to the human artery for compression treatment, and the electronic control component is connected to the compression device to control the action holding of the compression device. The air release device set in the electronic control component is a peristaltic air release pump. The radial artery compression hemostatic device detects the systolic blood pressure of the human body, and adds a pressure value P to the systolic blood pressure as the starting pressure P1, and then performs decompression successively, with each decompression value being the rounded P1 / 15 mmHg until the decompression is completed, which can achieve precise control of the air pressure of the radial artery compression hemostatic device, and full intelligent control of pressurization and decompression. It can not only effectively reduce the waste of labor costs, but also improve the working stability and reliability of the device.

[0005] Although the above solutions propose some methods related to the control of the radial artery compression hemostat, the existing technologies still have the following limitations: specifically, the existing technologies lack the highly personalized control ability of the radial artery compression hemostat.

[0006] On the one hand, for the initial pressure setting link of the existing radial artery compression hemostat for the wearing patients, it mostly relies on the systolic blood pressure of the patients obtained from wearing monitoring, simply adding the generally used preset pressure safety margin range in the industry, seriously ignoring the specific differences in the puncture operations of different patients and the physiological characteristics of the patients themselves, resulting in the inability to accurately determine the effective adaptation initial pressure that meets the actual needs of the patients, and greatly affecting the hemostasis effect.

[0007] On the other hand, for the decompression operation link of the existing radial artery compression hemostat for the wearing patients, the single decompression operation often mechanically follows the preset decompression amount, without fully considering the actual performance during the decompression process, making it difficult to flexibly adjust the decompression strategy, and may increase the occurrence probability of complications. Summary of the Invention

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

[0009] The technical solution adopted by the present invention to solve its technical problems is: In the first aspect, the present invention provides a smart control system for a radial artery compression hemostat, including: a reference initial pressure analysis module, a pressure application operation module, an initial hemostasis effect evaluation module, a decompression operation module, a reasonable evaluation module for decompression operation, and a wearing removal prompt module.

[0013] The initial hemostasis effect evaluation module is used to evaluate the initial hemostasis effect of the radial artery compression hemostat on the target patient and determine whether the expectation is met. If the judgment is negative, the initial pressure is continuously corrected and adapted until the initial hemostasis effect meets the expectation. At this time, the optimal allocation weights of the corresponding historical reference initial pressure and individual reference initial pressure are inversely analyzed and uploaded to the cloud database synchronously.

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

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

[0016] The wearing removal prompt module is used to perform the wearing removal prompt operation of the radial artery compression hemostat when the pressure balance state of the radial artery compression hemostat lasts for a preset duration.

[0017] In a second aspect, the present invention provides an intelligent control method for a radial artery compression hemostat, including: S1. Denote 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.

[0018] S2. Perform weight allocation on the historical reference initial pressure and individual reference initial pressure to determine the adapted initial pressure of the radial artery compression hemostat for the target patient, and perform the pressurization operation of the radial artery compression hemostat accordingly.

[0019] S3. Evaluate the initial hemostasis effect of the radial artery compression hemostat on the target patient and determine whether the expectation is met. If the judgment is negative, continuously correct and adapt the initial pressure until the initial hemostasis effect meets the expectation. Inversely analyze the optimal allocation weights of the corresponding historical reference initial pressure and individual reference initial pressure at this time, and upload them to the WEB cloud synchronously.

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

[0021] S5. Collect the overall decompression operation performance data of the radial artery compression hemostat on the target patient, and evaluate and feedback the reasonableness of the decompression operation of the radial artery compression hemostat on the target patient.

[0022] S6. Maintain the pressure balance state of the radial artery compression hemostat for a preset duration, and perform the operation of prompting the removal of the radial artery compression hemostat.

[0023] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) By retrieving the puncture operation information and physiological monitoring information of the target patient, the present invention conducts an individual reference initial pressure analysis and a historical reference initial pressure analysis of the radial artery compression hemostat from the perspectives of the individual medical performance of the target patient and the reference of historical experience, assisting in customizing the initial pressure setting for the target patient and providing a scientific basis for the use of the radial artery compression hemostat.

[0024] (2) By assigning weights to the historical reference initial pressure and the individual reference initial pressure, the present invention determines the adapted initial pressure of the radial artery compression hemostat for the target patient within the initial pressure safety range of the target patient, greatly reducing the possibility of risks caused to the patient by improper pressure settings, thereby ensuring the safety of the patient.

[0025] (3) The present invention continuously corrects the adapted initial pressure until the initial hemostasis effect of the radial artery compression hemostat for the target patient reaches the expectation, reversely analyzes the optimal distribution weights of the corresponding historical reference initial pressure and individual reference initial pressure at this time and synchronously uploads them, providing data support for subsequent patients wearing the radial artery compression hemostat, thereby realizing the continuous precise optimization of the initial pressure setting for patients wearing the radial artery compression hemostat.

[0026] (4) By real-time monitoring the hemostasis status of the target patient to determine whether the preset decompression decision condition is reached, and dynamically regulating 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, the present invention significantly improves the safety and effectiveness of the use of the radial artery compression hemostat, which is of great significance for improving the patient care quality and promoting the development of personalized medicine.

[0027] (5) By comprehensively considering the hemostasis maintenance level coefficient and the thrombus improvement level coefficient during the overall decompression operation of the target patient, the present invention evaluates the rationality of the decompression operation of the radial artery compression hemostat for the target patient, helps to effectively understand the decompression operation status of the radial artery compression hemostat, and thus assists in feedback on potential problems of the decompression operation.

[0028] The present invention is further described with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation to the present invention. For those of ordinary skill in the art, other drawings can also be obtained according to the following drawings without creative efforts.

[0031] Figure 3 This is the schematic diagram of the analysis logic of the individual reference initial pressure of the radial artery compression hemostat of the present invention for the target patient. Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 As shown, a smart control system for a radial artery compression hemostat according to a first aspect of the present invention includes: a reference initial pressure analysis module, a pressure application operation module, an initial hemostasis effect evaluation module, a pressure reduction operation module, a reasonable evaluation module for pressure reduction operation, and a wearing removal prompt module.

[0034] The reference initial pressure analysis module is connected to the pressure application operation module, the pressure application operation module is connected to the initial hemostasis effect evaluation module, the initial hemostasis effect evaluation module is connected to the pressure reduction operation module, the pressure reduction operation module is connected to the reasonable evaluation module for pressure reduction operation, and the reasonable evaluation module for pressure reduction operation is connected to the wearing removal 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 surgery 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, the numerical values of each coagulation function index, and the numerical values of each vascular elasticity index.

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

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

[0040] Referring to Figure 3 As shown, specifically, the specific analysis process of the reference initial pressure analysis module includes: according to the outer diameter range, puncture times range, and puncture angle range used by the puncture needle recorded in the puncture operation stored in the cloud database, standardize the maximum outer diameter value, puncture times, and maximum puncture angle in the puncture operation information of the target patient. After accumulation, substitute them into the natural exponential function to obtain the hemostasis difficulty correlation coefficient of the target patient affected by the surgical puncture.

[0041] It should be noted that the specific process of standardizing the maximum outer diameter value, puncture times, and maximum puncture angle in the puncture operation information of the target patient is as follows: extract the upper limit value and lower limit value of the outer diameter range used by the puncture needle recorded in the puncture operation. Take the calculation difference between the maximum outer diameter value of the puncture needle in the puncture operation information of the target patient and the lower limit value of the outer diameter range used by the puncture needle recorded in the puncture operation as the numerator, and take the calculation difference between the upper limit value and the lower limit value of the outer diameter range used by the puncture needle recorded in the puncture operation as the denominator, and conduct ratio analysis. Take the ratio analysis result as the value of the maximum outer diameter value of the puncture needle in the puncture operation information of the target patient after standardization. Similarly, standardize the puncture times and maximum puncture angle in the puncture operation information of the target patient.

[0042] According to the preset reasonable value ranges of diastolic blood pressure, various coagulation function indexes, and various blood vessel elasticity indexes corresponding to the normal physiological state stored in the cloud database, calculate the abnormal manifestation degrees corresponding to the diastolic blood pressure, various coagulation function indexes, and various blood vessel elasticity indexes of the target patient. After accumulation, substitute them into the natural exponential function to obtain the body hemostasis disorder coefficient of the target patient affected by the physiological state.

[0043] It should be noted that the specific calculation process of the abnormal manifestation degrees corresponding to the diastolic blood pressure, each coagulation function index, and each vascular elasticity index of the above-mentioned target patient is as follows: 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, set the abnormal manifestation degree corresponding to the diastolic blood pressure of the target patient to 0. If the diastolic blood pressure of the target patient is less than the lower limit value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, further perform a ratio analysis on the absolute difference between the diastolic blood pressure of the target patient and the lower limit value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, and the lower limit value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, to obtain the abnormal manifestation 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 value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, further perform a ratio analysis on the difference between the diastolic blood pressure of the target patient and the upper limit value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, and the upper limit value of the preset reasonable numerical range of the diastolic blood pressure corresponding to the normal physiological state of the human body, to obtain the abnormal manifestation degree corresponding to the diastolic blood pressure of the target patient. Similarly, calculate the abnormal manifestation degrees corresponding to each coagulation function index and each vascular elasticity index of the target patient.

[0044] Use the cumulative value of the hemostasis difficulty related coefficient and the body hemostasis disorder coefficient as the comprehensive hemostasis evaluation factor, perform a multiplication operation with the preset hemostasis pressure application value corresponding to the unit comprehensive hemostasis evaluation factor stored in the cloud database, and add the rounded-up result of the multiplication operation 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 further includes: Extract the uploaded content of the pressure application operations of each historical patient wearing a radial artery compression hemostat stored in the cloud database, including the hemostasis difficulty related coefficient, the body hemostasis disorder coefficient, the initial pressure corresponding to effective hemostasis, its corresponding historical reference initial pressure, and the optimal distribution weight of the individual reference initial pressure. Compare the hemostasis difficulty related coefficient and the body hemostasis disorder coefficient of each historical patient wearing a radial artery compression hemostat with those of the target patient, and screen out each historical patient wearing a radial artery compression hemostat with a high similarity to the current wearing status of the target patient, and record them as each historical reference patient.

[0046] It should be noted that the specific screening process for each of the above historical reference patients is as follows: Calculate the absolute difference between the hemostasis difficulty correlation coefficient of each patient who has previously worn the radial artery compression hemostat and that of the target patient, and perform a ratio analysis with the hemostasis difficulty correlation coefficient of the target patient to obtain the deviation ratio of the hemostasis difficulty correlation coefficient between each patient who has previously worn the radial artery compression hemostat and the target patient. Similarly, calculate and obtain the deviation ratio of the body hemostasis disorder coefficient between each patient who has previously worn the radial artery compression hemostat and the target patient. Add the deviation ratio of the blood hemostasis difficulty coefficient and the deviation ratio of the body hemostasis disorder coefficient, and substitute the negative value of the cumulative value into the natural exponential function to obtain the similarity evaluation index, thereby obtaining the similarity evaluation index between each patient who has previously worn the radial artery compression hemostat and the target patient. If the similarity evaluation index between a patient who has previously worn the radial artery compression hemostat and the target patient is greater than the preset similarity evaluation index compliance threshold, it indicates that there is a high similarity between the current wearing status of the patient who has previously worn the radial artery compression hemostat and the target patient. The patient who has previously worn the radial artery compression hemostat is recorded as a historical reference patient, and each historical reference patient is screened in this way.

[0047] Calculate the average value of the initial pressures corresponding to effective hemostasis for each historical reference patient to obtain the historical reference initial pressure of the radial artery compression hemostat for the target patient.

[0048] In the embodiment of the present invention, by retrieving the puncture surgery information and physiological monitoring information of the target patient, from the perspective of the individual medical performance of the target patient and the reference of historical experience, the individual reference initial pressure analysis and historical reference initial pressure analysis of the radial artery compression hemostat for the target patient are carried out, assisting in the customized initial pressure setting for the target patient, and providing a scientific basis for the use of the radial artery compression hemostat.

[0049] The pressure application operation module is used to assign weights to 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 application operation of the radial artery compression hemostat accordingly.

[0050] Specifically, the specific analysis of the pressure application operation module includes: determining the initial pressure safety range of the target patient according to the reserved safety pressure range 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 initial pressure safety range of the above target patient is the cumulative value of the systolic blood pressure of the target patient 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 initial pressure safety range of the target patient is the cumulative value of the systolic blood pressure of the target patient and the lower limit value of the reserved safety pressure range corresponding to the initial pressure setting of the radial artery compression hemostat.

[0052] Extract the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure corresponding to the effective hemostasis of each historical patient wearing a radial artery compression hemostasis device, construct each historical weight allocation reference combination, calculate the relative prevalence of each historical weight allocation reference combination, screen the historical weight allocation reference combination corresponding to the maximum relative prevalence, and use the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure corresponding to the effective hemostasis of the corresponding historical patient wearing a radial artery compression hemostasis device contained therein to perform weight allocation on the historical reference initial pressure and the individual reference initial pressure. Accumulate the products of the historical reference initial pressure and the individual reference initial pressure of the radial artery compression hemostasis device for the target patient and their corresponding allocated weights respectively to obtain the reasonable reference initial pressure of the radial artery compression hemostasis device for the target patient. Determine the adaptive initial pressure of the radial artery compression hemostasis device for the target patient according to its comparison relationship with the safety interval of the initial pressure of the target patient.

[0053] It should be noted that the above-mentioned historical weight allocation reference combinations and each historical patient wearing a radial artery compression hemostasis device are in a corresponding relationship, that is, each historical weight allocation reference combination contains the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure corresponding to the effective hemostasis of the corresponding historical patient wearing a radial artery compression hemostasis device.

[0054] The specific calculation process of the relative prevalence of the above-mentioned historical weight allocation reference combinations is as follows: Extract a certain historical weight allocation reference combination, and analyze the deviation measurement index between this historical weight allocation reference combination and other historical weight allocation reference combinations through the Euclidean distance calculation formula. If the deviation measurement index between 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. Thus, count the number of similar item combinations of this historical weight allocation reference combination, and take the ratio of it to the total number of historical weight allocation reference combinations as the relative prevalence of this historical weight allocation reference combination. Similarly, calculate and obtain the relative prevalence of each historical weight allocation reference combination.

[0055] It should also be noted that the specific determination process of the initial adaptation pressure of the above-mentioned 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 initial pressure safety range of the target patient, then the reasonable reference initial pressure of the radial artery compression hemostat for the target patient is determined as the initial adaptation 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 initial pressure safety range of the target patient, then the upper limit value of the initial pressure safety range of the target patient is determined as the initial adaptation 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 initial pressure safety range of the target patient, then the lower limit value of the initial pressure safety range of the target patient is determined as the initial adaptation pressure of the radial artery compression hemostat for the target patient.

[0056] In the embodiment of the present invention, by assigning weights to the historical reference initial pressure and the individual reference initial pressure, the initial adaptation pressure of the radial artery compression hemostat for the target patient is determined within the initial pressure safety range of the target patient, greatly reducing the possibility of risks caused to the patient by improper pressure settings, thereby ensuring the safety of the patient.

[0057] The initial hemostasis effect evaluation module is used to evaluate the initial hemostasis effect of the radial artery compression hemostat for the target patient and determine whether it reaches the expectation. If the determination is no, then continuously correct the initial adaptation pressure until the initial hemostasis effect reaches the expectation, and inversely analyze the optimal allocation weights of the corresponding historical reference initial pressure and individual reference initial pressure at this time, and synchronously upload them to the cloud database.

[0058] Specifically, the specific analysis process of the initial hemostasis effect evaluation module includes: collecting the effective hemostasis index values, cumulative blood loss, and swelling rate of the puncture position of the target patient within a preset time period. Among them, 1 indicates that the puncture position has been effectively hemostatic, and 0 indicates that the puncture position has not been effectively hemostatic. Analyze the initial hemostasis effect evaluation index of the radial artery compression hemostat for the target patient by the formula , which are the preset reference cumulative blood loss and swelling rate respectively.

[0059] If the initial hemostasis effect evaluation index of the radial artery compression hemostat for the target patient is greater than the preset standard threshold of the hemostasis effect evaluation index, it is determined that the initial hemostasis effect reaches the expectation; otherwise, it is determined that the initial hemostasis effect does not reach the expectation.

[0060] When it is determined that the initial hemostasis effect does not meet the expectation, obtain the absolute difference between the initial hemostasis effect evaluation index and its preset standard threshold, and multiply the absolute difference by the corresponding preset corrected initial pressure of the unit initial hemostasis effect evaluation index stored in the cloud database, so as to correct and adapt the initial pressure. Repeat the above process after experiencing the next preset time period until it is determined that the initial hemostasis effect meets the expectation.

[0061] It should be noted that the specific process of the above reverse analysis corresponding to the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure at this time is as follows: obtain the adapted initial pressure corresponding to when the initial hemostasis effect of the radial artery compression hemostat for the target patient reaches the expectation, and set the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure to meet the constraint condition that the cumulative value is 1, so as to generate a series of test groups, and the test groups include the historical reference initial pressure and the test allocation weights corresponding to the individual reference initial pressure.

[0062] Accumulate the products of the historical reference initial pressure and the individual reference initial pressure of the radial artery compression hemostat for the target patient and the test allocation weights set for each test group respectively, obtain the reasonable reference initial pressure of the radial artery compression hemostat for the target patient corresponding to each test group by inference, take the absolute value difference from the adapted initial pressure corresponding to when the initial hemostasis effect of the radial artery compression hemostat for the target patient reaches the expectation, screen 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, and determine them as the optimal allocation weights of the historical reference initial pressure and the individual reference initial pressure.

[0063] In the embodiment of the present invention, the adapted initial pressure is continuously corrected until the initial hemostasis effect of the radial artery compression hemostat for the target patient reaches the expectation, and the optimal allocation weights of the corresponding historical reference initial pressure and the individual reference initial pressure are reversely analyzed and uploaded synchronously, providing data support for subsequent patients wearing the radial artery compression hemostat, so as to continuously and precisely optimize the setting of the initial pressure 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, judge whether the preset decompression decision condition is reached, and thus 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 the 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 hemostasis effect reaches the expectation, analyze the hemostasis demand degree and blood perfusion demand degree of the target user in real time. When the difference between the hemostasis demand degree and the blood perfusion demand degree is less than or equal to the preset value, it is determined that the hemostasis status of the current target patient reaches the preset decompression decision condition.

[0066] It should be noted that the specific process of the above real-time analysis of the hemostasis demand degree and blood perfusion demand degree of the target user is as follows: starting from the time point when it is to be determined that the initial hemostasis effect reaches the expectation, continuously collect the effective hemostasis index value, cumulative blood loss and swelling speed at the puncture position of the target patient. It is the same as the analysis method of the initial hemostasis effect evaluation index of the radial artery compression hemostat for the target patient. After obtaining the time point when the initial hemostasis effect reaches the expectation, obtain the hemostasis effect evaluation index of the radial artery compression hemostat for the target patient at each unit time point. If it is greater than or equal to the preset standard threshold of the hemostasis effect evaluation index, obtain the interval duration relative to the time point when it is determined that the initial hemostasis effect reaches the expectation, perform ratio analysis with the preset reference interval duration, and substitute the negative value of the ratio analysis result into the natural exponential function to obtain the hemostasis demand degree of the target user at the corresponding unit time point. If it is less than the preset standard threshold of the hemostasis effect evaluation index, directly set the hemostasis demand degree of the target user at the corresponding unit time point to 1.

[0067] Starting from the time point when it is to be determined that the initial hemostasis effect reaches the expectation, real-time collect the blood oxygen saturation and heart rate value of the target patient, and obtain the relative heart rate increase amplitude of the target patient at each unit time point after the time point when the initial hemostasis effect reaches the expectation and the relative blood oxygen decrease amplitude , where is the number of each unit time point, , and calculate the blood perfusion demand degree of the target patient at each unit time point after the time point when the initial hemostasis effect reaches the expectation according to the formula , are the preset permitted heart rate increase amplitude and the preset permitted blood oxygen decrease amplitude respectively.

[0068] Set the decompression amount of the first decompression operation as the preset decompression amount, monitor the degree of weakening of the hemostasis effect and the improvement degree of blood flow embolism of the target patient during the preset decompression interval duration corresponding to the first decompression operation, and determine the decompression adjustment coefficient of the next decompression operation according to the cumulative value of the product of the degree of weakening of the hemostasis effect and the improvement degree of blood flow embolism and their corresponding preset weights , and use the product of the decompression adjustment coefficient and the preset decompression amount as the decompression amount corresponding to the next decompression operation, and repeat the above process to realize the dynamic regulation of the decompression amount of each decompression operation.

[0069] It should be noted that the degree of weakening of the hemostasis effect and the improvement degree of blood flow embolism of the target patient during the preset decompression interval duration corresponding to the first decompression operation both refer to the content of the decompression operation scoring standard preset in the cloud database, and specifically collect the newly increased blood loss and the increased blood flow speed of the target patient during the preset decompression interval duration corresponding to the first decompression operation for corresponding evaluation.

[0070] It should also be noted that the specific determination process of the decompression adjustment coefficient for the above-mentioned next decompression operation is as follows: extract the execution operation threshold of the content specification of the preset decompression operation scoring standard When , it indicates that the degree of weakening of the hemostatic effect is relatively low and the degree of improvement of blood flow embolism is relatively low. Determine the decompression adjustment coefficient for the next decompression operation to be 0.8.

[0071] When , it indicates that the degree of weakening of the hemostatic effect is relatively high and the degree of improvement of blood flow embolism is relatively high. Determine the decompression adjustment coefficient for the next decompression operation to be 1.2.
