[0017] The present application embodiment provides a workflow of a venipuncture angiography instrument, such as Figure 1 As shown, including: S101: Collecting metadata information of the site to be punctured from the medical records of the patient to be punctured; S102: generating an image score of the visualization quality of each subcutaneous venous blood vessel included in the site to be punctured based on the site to be punctured and metadata information of the site to be punctured; S103: Generate the similarity of each puncture history information through the subcutaneous vein blood vessels contained in each puncture history information in the medical record database and the image score of the subcutaneous vein blood vessels of the patient to be punctured for the development quality of the subcutaneous vein blood vessels; the similarity of the puncture history information is proportional to the number of operations performed by the operator on the puncture history information, and the medical record database stores the puncture history information of the medical record; S104: determining the current puncture reference information of the patient to be punctured by the similarity of each puncture history information in the medical record database, wherein the current puncture reference information includes the puncture history information of a plurality of medical records.
[0018] Optionally, in one embodiment of the present application, generating an image score of the development quality of each subcutaneous vein included in the site to be punctured includes: generating an image score of the development quality of each subcutaneous vein included in the site to be punctured by normal distribution. The image score of the development quality of the subcutaneous vein refers to the score of the development quality of the subcutaneous vein of the patient to be punctured to be inferred after knowing the "result" of "metadata information of the site to be punctured". This score describes the most likely value of the development quality of the subcutaneous vein of the patient to be punctured. The development quality of the subcutaneous vein is used to describe the number of operations on the subcutaneous vein of the patient to be punctured.
[0019] The medical record database stores a large amount of puncture history information of the medical records. In some embodiments of the present application, the large amount of puncture history information stored in the medical record database can also be classified according to the interference band level, so that the patient to be punctured can select the puncture history information from the puncture history information of a specific interference band for injury.
[0020] In this embodiment, after obtaining the trailing edge score of the patient to be punctured on the development quality of each subcutaneous vein through the metadata information of the site to be punctured, the similarity of each puncture history information can be determined in combination with the subcutaneous vein contained in each puncture history information in the medical record library and the image score of the patient to be punctured on the development quality of the subcutaneous vein; when the similarity of each puncture history information in the medical record library is generated, the current puncture reference information of the patient to be punctured can be determined through the similarity of each puncture history information, so as to achieve the purpose of adaptively recommending to the patient to be punctured the puncture history information with poor development quality of the subcutaneous vein, thereby improving the damage effect of the patient to be punctured on the recommended puncture history information, and helping the patient to be punctured to effectively associate the subcutaneous veins that have been done but with poor proficiency.
[0021] Based on the above embodiments, in one embodiment of the present application, Figure 2 As shown, the working method of the venipuncture angiography instrument includes: S201: Collecting metadata information of the site to be punctured from the medical records of the patient to be punctured; S202: Analyze the site to be punctured, collect the subcutaneous veins contained in the site to be punctured and the similarity between the site to be punctured and the subcutaneous veins; S203: inputting metadata information of the site to be punctured and the similarity between the site to be punctured and the subcutaneous vein into a first conditional algorithm to generate an image score for the visualization quality of the site to be punctured and the subcutaneous vein; The first condition algorithm is: ; Among them, G K is the imaging quality of subcutaneous venous vessels K, S i is the metadata information of the i-th puncture operation, W(A i , K) is the puncture history information A i The similarity with the subcutaneous vein K, α and β are two parameters of the normal function, which are the importance coefficients of the subcutaneous vein K being displayed and not displayed respectively; S204: Generate the similarity of each puncture history information by using the subcutaneous veins contained in each puncture history information in the medical record database and the image score of the subcutaneous vein development quality of the patient to be punctured; the similarity of the puncture history information is proportional to the number of operations performed by the operator on the puncture history information, and the medical record database stores the puncture history information of the medical record; S205: Determine the current puncture reference information of the patient to be punctured by the similarity of each puncture history information in the medical record database, wherein the current puncture reference information includes the puncture history information of a plurality of medical records.
[0022] The step of analyzing the site to be punctured and collecting the subcutaneous veins contained in the site to be punctured and the similarity between the site to be punctured and the subcutaneous veins includes: S2021: Analyze the site to be punctured, and collect subcutaneous veins included in the site to be punctured; S2022: generating a similarity between each of the subcutaneous veins and the site to be punctured; The generating of the similarity between each subcutaneous vein and the site to be punctured comprises: S20221: Counting the total number of puncture operations involving the subcutaneous vein in the medical record database, and the frequency of damage to the subcutaneous vein by the patient to be punctured; S20222: Inputting the frequency of injury to the subcutaneous vein of the patient to be punctured, the total number of puncture operations involving the subcutaneous vein, and the total number of all puncture operations in the medical record database into a second conditional algorithm to generate a similarity between each subcutaneous vein and the site to be punctured; The second condition algorithm is: ; Among them, N A is the total number of all puncture operations in the medical record database, is the total number of puncture operations involving the subcutaneous venous blood vessels, is the extension of the injury frequency of the subcutaneous vein K of the patient to be punctured, and , where C K is the frequency of damage to the subcutaneous vein K by the patient to be punctured; In this embodiment, a specific method for generating an image score of the visualization quality of each subcutaneous vein included in the puncture site through the puncture site and its metadata information is provided.
[0023] In the first conditional algorithm, α and β are two parameters of the normal function, which are the importance coefficients of the subcutaneous vein K being visible and not visible. That is, after each puncture operation is completed on the patient to be punctured, a metadata information S for the puncture operation will be obtained. i , when the metadata information S of the puncture operation i Greater than or equal to the set upper limit S h When (ie S i ≥S h When the metadata information S of the puncture operation is i Less than the set upper limit S h When (ie S i h When the current value of β is increased by 1, the new value of β is obtained. If the imaging quality of the subcutaneous venous blood vessel included in the puncture operation is generated by the first conditional algorithm, the new values of α and β need to be saved at the same time.
[0024] Based on the above embodiment, in another embodiment of the present application, Figure 3 As shown, the working method of the venipuncture angiography instrument includes: S301: Collecting metadata information of the site to be punctured from the medical records of the patient to be punctured; S302: Generate an image score of the visualization quality of each subcutaneous vein included in the site to be punctured based on the site to be punctured and metadata information of the site to be punctured; S303: collecting interference bands of each puncture history information in the medical record database; S304: inputting the medical history of the patient to be punctured, the most interfering bands of all subcutaneous veins in all puncture history information in the medical record database, and the most interfering bands of subcutaneous veins contained in each puncture history information into a fifth condition algorithm to generate a third similarity for each puncture history information; The fifth condition algorithm is: ; Among them, Age is the medical history of the patient to be punctured, Age1 is a positive integer greater than 0, which is the upper limit of the medical history of the condition; MaxD is the maximum interference band of all subcutaneous veins in all puncture history information in the medical record database; MaxAD is the maximum interference band of subcutaneous veins contained in the puncture history information; S305: taking the sum of the interference band of each puncture history information and the third similarity of the puncture history information as the similarity of the puncture history information; the puncture history information of the medical record is stored in the medical record database; S306: collecting the top M puncture history information with the largest similarity to the puncture history information in the medical record database as the puncture history information in the current puncture reference information of the patient to be punctured; S307: Arranging the M pieces of collected puncture history information in order of conditions by using interference bands of the M pieces of collected puncture history information to obtain current puncture reference information of the patient to be punctured.
[0025] In this embodiment, steps S303-S305 provide a feasible method for specifically generating the similarity of each puncture history information, that is, firstly collecting the interference band of the puncture history information, then generating the third similarity of the puncture history information through the fifth condition algorithm, and finally taking the sum of the interference band of the puncture history information and the third similarity as the final similarity of the puncture history information. The final similarity represents whether the puncture history information needs to be associated, and the greater the similarity, the more the associated puncture operation should be associated.
[0026] Optional, such as Figure 4 As shown, the interference bands for collecting each of the puncture history information in the medical record library include: S3031: Counting the injury frequency of each subcutaneous vein included in each puncture history information of the patient to be punctured in the medical record database, determining the first similarity of each subcutaneous vein included in each puncture history information of the patient to be punctured in the medical record database through a third condition algorithm, and superimposing the first similarities of the patient to be punctured to all subcutaneous veins included in the puncture history information as the first similarity of the puncture history information; The third condition algorithm is: ; Among them, f K1 is the first similarity of the subcutaneous vein K contained in the puncture history information, C i is the injury frequency of the subcutaneous vein i contained in the puncture history information of the patient to be punctured, N is a positive integer greater than zero, and is the upper limit of the conditional frequency; S3032: Counting the average second similarity of the patient to be punctured to all subcutaneous veins under each puncture history information in the medical record database as the second similarity of each puncture history information; The second similarity of the subcutaneous vein is generated by a fourth condition algorithm, and the fourth condition algorithm is: K2 =1-P(G K ), where f i2 is the second similarity of the subcutaneous vein K, P(G K ) is the image score of the development quality of subcutaneous vein K.
[0027] In the third conditional algorithm, the value of the conditional frequency upper limit N can be actually determined by factors such as the type of medical records. When the medical records are in English, the value of the conditional frequency upper limit can be 4 through the injury data of a large number of operators and the forgetting curve analysis; but in other embodiments of the present application, the value of the conditional frequency upper limit can also be 3 or 5 or other values. In the third conditional algorithm, when the injury frequency of the subcutaneous vein i of the patient to be punctured is greater than or equal to N, the first similarity of the subcutaneous vein i is 0, that is, it is considered that the subcutaneous vein does not need to be associated; when the injury frequency of the patient to be punctured to the subcutaneous vein i is less, the value of the first similarity of the subcutaneous vein is closer to 1, that is, the patient to be punctured should be associated with the subcutaneous vein.
[0028] In addition, steps S306-S307 in this embodiment provide a method for determining the current puncture reference information of the patient to be punctured specifically through the similarity of each puncture history information in the medical record library, that is, firstly arranging the puncture history information in the medical record library in order of similarity from large to small, and then taking the first M puncture history information with relatively large similarity as the current puncture reference information of the patient to be punctured.
[0029] Wherein, M is a positive integer greater than or equal to 1.
[0030] Optionally, the arrangement order of these M puncture history information in the current puncture reference information can be the order of interference bands from small to large and then from large to small, so as to achieve the effect of the puncture operations in the current academic list from simple to difficult and then from difficult to simple, which is conducive to helping the patient to be punctured enter the injury state faster and improve the injury effect on the patient to be punctured.
[0031] Based on the above embodiment, in another embodiment of the present application, Figure 5 As shown, the working method of the venipuncture angiography instrument includes: S401: Collecting metadata information of the site to be punctured from the medical records of the patient to be punctured; S402: Generate an image score of the visualization quality of each subcutaneous vein included in the site to be punctured based on the site to be punctured and metadata information of the site to be punctured; S403: Generate the similarity of each puncture history information through the subcutaneous veins contained in each puncture history information in the medical record database and the image score of the subcutaneous vein development quality of the patient to be punctured; the similarity of the puncture history information is proportional to the number of operations performed by the operator on the puncture history information, and the medical record database stores the puncture history information of the medical record; S404: collecting the historical average injury duration and the historical total injury duration of the patient to be punctured; S405: inputting the historical average injury duration of the patient to be punctured into the sixth condition algorithm to generate a recommended puncture operation light source intensity, and using the recommended puncture operation light source intensity as the puncture operation light source intensity included in the current puncture reference information of the patient to be punctured; The sixth condition algorithm is: ; Where X is the recommended puncture operation light source intensity, L0 is the historical average injury duration of the patient to be punctured, L1 is the historical total injury duration, X0 is the conditional puncture reference information puncture operation light source intensity S406: Determine the current puncture reference information of the patient to be punctured through the similarity of each puncture history information in the medical record database and the intensity of the light source for the recommended puncture operation, wherein the current puncture reference information includes puncture history information of multiple medical records.
[0032] In this embodiment, steps S404-S405 provide a method for determining the puncture operation light source intensity contained in the current puncture reference information provided to the patient to be punctured each time according to the actual injury condition of the patient to be punctured. Specifically, the ratio of the historical average injury duration and the historical total injury duration of the patient to be punctured is used as a coefficient for determining the question amount, and the product of the coefficient and the conditional puncture operation light source intensity of the puncture reference information is used as the recommended puncture operation light source intensity for the patient to be punctured. The recommended puncture operation light source intensity is the puncture history information of the patient to be punctured that is included in the medical record in the current puncture reference information.
[0033] The recommended puncture operation light source intensity determined in this way comprehensively considers the relationship between the historical average injury time and the historical total injury time of the patient to be punctured, so that the patient to be punctured will not feel that there are too many or too few puncture operations after completing a set of puncture history information in the current puncture reference information, which is conducive to improving the injury enthusiasm of the patient to be punctured.
