In the embodiment of the invention, the differentiated case generation characteristic training needs huge training sample data, and the data comprises known medical knowledge data, hospital existing case information, department existing case information and doctor personal existing case information. And finding out a personalized case generation basis through feature recognition. This also requires interfacing with public network medical databases, hospital private network medical databases, department private network medical databases, and doctor personal medical databases. Preferably, the database access is carried out by acquiring information access keys of departments and doctors of the hospital, and relevant data acquisition can be carried out only through the acquisition units 10 which are legal for records of the departments and the doctors of the hospital, so that information leakage of the doctors and patients is avoided.

Meanwhile, the pushing module 402 is connected with a printing end for conveniently and timely printing cases and increasing the use convenience of the system.
Fig. 1 is a flowchart of a method for generating a personalized electronic case according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a personalized electronic case generation method, including: constructing a knowledge graph according to the existing medical data; acquiring existing case information, and structuring the existing case information according to the knowledge graph to obtain structured data; performing deep simulation training according to the structured data and the existing case information to obtain a case generation model; and generating personalized cases according to the case generation model.
Specifically, the generation of the current case mainly depends on a template, different templates need to be configured for different departments or diseases, and the method is not only complicated, but also not flexible enough, and cannot well support complex clinical scenes. And the habits of patients and doctors in different hospitals, different departments of the same hospital and different doctors in the same department are different, and if the unified case template specification is carried out, the unified case template cannot be guaranteed to be suitable for all disease condition lists on one hand, and on the other hand, the personalized requirements of each hospital, department and doctor cannot be met. Therefore, in order to perform personalized case generation without hospitals, different departments, different doctors and different diseases, the rules of cases without hospitals, different departments, different doctors and different diseases need to be known respectively, and differential case generation is performed according to the rules, so that the information listing efficiency of cases is improved, and the personalized case requirements without hospitals, different departments, different doctors and different diseases are met. Specifically, the method comprises the following steps:
step S10: and constructing a knowledge graph according to the existing medical data.
Specifically, when acquiring the case rule without using a hospital, different departments, different doctors and different diseases, enough data samples need to be acquired first, and the larger the data samples are, the more the summarized rule is fit to the reality. In order to obtain more complete medical data, the acquisition unit 10 is constructed from various databases. It is necessary to acquire regular data of case information, so that it is necessary to acquire a large amount of known case information and medical knowledge information. For example, through comparison and judgment of a large amount of case information, the main contents of conventional case information include main complaints, current medical history, past history, personal history, family history, menstrual marriage and childbirth history, and the structural map lists relatively wide contents and completely records the state information of patients. And (4) performing medical knowledge retrieval aiming at the summarized conventional case structure map, and filling known illness state knowledge corresponding to each structural unit. For example, the current medical history includes various symptoms, signs and medication conditions known, and the family history includes various genetic diseases and family infringements. The information has complete clinical experience and the structural units are mutually connected. For example, in the case of fever and cold, symptoms such as fever, cough, thin nasal discharge and the like are often accompanied, the relationship interconnection of the structural units is performed, the relationship interconnection of the content of each unit is performed, after doctor diagnosis information is obtained at a later stage, the corresponding current medical history and past medical history can be automatically generated or associated, and through association input, the workload of doctors is reduced, and the case generation efficiency is improved.
On the other hand, although the existing case structure map is complete in recording the patient condition information, the structure map is not suitable for all departments and all doctors. For example, when a common bone fracture patient is treated by a common orthopedic outpatient service, only known common bone fractures need to be diagnosed and administered, other contents such as family history and menstruation, marriage and childbirth history do not need to be filled and confirmed except current medical history and past medical history, but the template vacancy information reduces the user experience, so that template customization needs to be performed according to the actual diagnosis and treatment conditions of each department, and the flexibility of case generation is reduced. Therefore, in the second aspect, it is necessary to determine the contents of the normal records generated by the medical record generation performed by each department and doctor by interfacing the medical database of each department with the medical database of the doctor. For example, the doctor is judged to be a common fever clinic doctor by sorting all case information recorded by the doctor, and the doctor has concise records for patient chief complaints and only introduces the most core symptoms and duration; while another physician has a thorough record of patient complaints, including all symptoms and duration of all symptoms. Aiming at the personal preferences of the two doctors, in order to make the generated case information follow the personal habits of the doctors, the personal knowledge graph of the corresponding doctors needs to be generated, so that the case generation training which is adapted to the personal habits of the doctors is performed in a targeted manner when the case generation training is performed in the later period, and the training trial-and-error rate is reduced. According to the above rules, different hospitals have different habits of generating cases, such as general clinics, orthopedic hospitals, gynecological hospitals and general hospitals, and the same hospital has different departments, so the habits of writing cases for different hospitals, different departments and different doctors are preferably generated correspondingly on the basis of the known public network medical data and the conventional case structure map, and the knowledge map is the training basic data of the corresponding hospital, department or doctor. Through the sorted differentiated big data, targeted case rule statistics is carried out, so that case high-frequency units of hospitals, departments or doctors can be obtained, and corresponding case history content display can be carried out according to personal preference.
Step S20: and acquiring the information of the existing case, and structuring the information of the existing case according to the knowledge graph to obtain structured data.
Specifically, after acquiring basic data of each hospital, each department and each doctor, that is, the correspondingly constructed knowledge graph, a targeted case generation simulation can be performed according to the corresponding knowledge graph. The process of case generation is to regularly count disordered patient chief complaint information and doctor diagnosis and treatment information into each knowledge map unit and finally to differentially present the information to the patient and the doctor. Preferably, case generation training is performed using a deep learning algorithm. Deep learning is the final ideal of artificial intelligence development, and the machine has the ability of analyzing and learning like a human by learning the internal rules and the representation levels of sample data. Therefore, the basic condition for deep learning is that a large amount of sample data needs to be prepared, and the final learning result is obtained through the rule that the machine finds the sample data and the trial-and-error training for countless times. In the personalized case generation method, sample data are messy patient chief complaint information and doctor diagnosis and treatment information which are hidden in the existing case information texts, and cases can be fictional or known. The known case information is imported into the processing unit 20, and the processing unit 20 performs corresponding case information structuring according to the generated knowledge maps of hospitals, departments and doctors, such as the above-mentioned common orthopedics clinic, and only the chief complaint, the current medical history and the past history are structured to obtain corresponding structured data. These structured data are sample data for case generation training performed by the processing unit 20, and in order to reduce trial and error rate and increase the probability that the training set results are close to reality, targeted case generation training is performed for different hospitals, different departments and different doctors, and thus, targeted sample data needs to be prepared. And respectively obtaining the corresponding structured data of each hospital, each department and each doctor according to the generated knowledge graph of each hospital, each department and each doctor.
Step S30: and carrying out deep simulation training according to the structured data and the existing case information to obtain a case generation model.
Specifically, structured data of each hospital, each department and each doctor is obtained as a training data sample, and a corresponding case is generated as a training result to adapt to new training. The deep learning algorithm has many types, mainly including three types, namely a neural network system based on convolution operation, a self-coding neural network based on multilayer neurons, and pre-training in a multilayer self-coding neural network manner, the case information is various and complex, and if the unsupervised self-coding neural network based on multilayer neurons and the pre-training algorithm in the multilayer self-coding neural network manner are performed, the amount of training sample data is too large, the calculation requirement on the processing unit 20 is very high, which not only aggravates the working load of the processing unit 20, but also reduces the training efficiency. Therefore, in order to achieve both training efficiency and fitting of training results to reality, it is preferable to select a convolutional neural network algorithm for supervised learning to perform case generation training. The convolutional neural network algorithm has the characteristic learning capacity and can carry out translation invariant classification on input information according to the hierarchical structure of the convolutional neural network algorithm. The preliminary steps of deep learning supervised learning are completed through the constructed structured data of each hospital, each department and each doctor, namely, the data needing to be trained is extracted, the information content of cases which are never used by each hospital, each department or each doctor is deleted, only the sample data needing to be trained is reserved, the training data amount is reduced, and the probability of feature extraction of the processing unit 20 is increased. The processing unit 20 performs case simulation generation through a convolutional neural network algorithm, simulates a specific hospital, a specific department or a specific doctor to perform case generation, simulates each piece of known case information to generate a corresponding personalized case, and obtains a case generation model of each hospital, a case generation model of each department and a case generation model of each doctor through a large amount of feature simulation training. The generated case generation model is stored in the storage unit 30, facilitating the case generation unit 40 to perform model extraction.
Step S40: and generating personalized cases according to the case generation model.
Specifically, the patient condition information and the diagnosis and treatment information of the patient are acquired in real time, and the uploading information of the doctor and the chief complaint information of the patient are recorded. When a patient needs to be generated, if a person is the patient, the case production unit generates personalized cases according to the patient visit hospital, department or doctor. The diagnosis and treatment information of the patient, the diagnosis information uploaded by the doctor and the patient chief complaint information are structured according to the corresponding knowledge map, namely, disordered information is normalized and characterized, and then corresponding personalized case generation is carried out according to the generated case generation models of hospitals, departments and doctors and is sent to the patient end. If the artificial doctor is initiated, personalized case generation is carried out on the structured information of the patient according to the case generation model corresponding to the doctor, and a case meeting personal habits and preferences of the doctor is automatically generated on the premise of not needing handwriting of the doctor, so that the case output efficiency is improved, and the accuracy of the coming case is also improved.
In one possible embodiment, the clinical information of the patient is uploaded to a public medical information base, and only the patient himself or the doctor who is interfacing can access the information by means of the patient personal information key. When a patient goes from one hospital to another hospital for diagnosis and treatment, the personal information key of the patient is used for accessing information such as the past history and family history of the patient, and the amount of information accessed by doctors and the amount of information complained by the patient are reduced. When patient medical record is generated, the patient information can be directly extracted conveniently, so that the generated patient medical record information is more comprehensive and accurate.
