Description

Technical Field

[0001] The present invention belongs to the field of intelligent medical construction, and particularly relates to a method for online medical consultation based on virtual outbound calls. Background Art

[0002] Each physical hospital has established an Internet hospital that can conduct online medical consultations and issue prescriptions. However, during the use of the online Internet hospital, various problems will still be faced.

[0003] One of the most prominent problems is that the main way of doctor-patient communication in current Internet online medical consultations is through IM chat. This leads to the problem that when the doctor sends a message to the patient, the patient is not online and cannot reply in time, resulting in poor doctor-patient communication, hindering the normal and smooth progress of online medical consultations, and causing a very poor experience for both doctors and patients.

[0004] Patients make appointments with doctors at the online Internet hospital, and doctors receive patients online to start doctor-patient interaction. Doctors and patients communicate through an IM chat tool. Since patients and doctors cannot receive messages in a timely manner, message notifications are not in place and not timely, which may cause the duration of a diagnosis and treatment process to take several hours or even the next day to complete, resulting in a very poor experience for both doctors and patients. This has greatly affected the promotion of online medical consultations and follow-up prescription dispensing services in Internet hospitals. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the present invention provides an online medical consultation system and method based on virtual outbound calls. By introducing the virtual outbound call function, and on this basis, using the audio obtained from the virtual outbound call for phonetic conversion, extracting key information and saving it to the patient's medical record, an initial medical record can be further quickly generated, helping doctors improve the efficiency of medical consultations. The present invention effectively solves the problem of untimely and unsmooth doctor-patient communication, and at the same time reduces the pressure on doctors for writing medical records, improving the efficiency and satisfaction of medical consultations in Internet hospitals.

[0006] The present invention can utilize the virtual outbound call function of the online Internet hospital to solve the drawbacks of untimely message notifications in doctor-patient communication, and the situation where doctors and patients cannot receive messages in a timely manner and communicate about the condition simultaneously while being online. By adopting the function of virtual mobile phone number outbound calls on the Internet hospital software, doctors and patients can make timely phone calls through virtual numbers during the consultation period, thus not relying on instant messaging (IM), and preventing the leakage of doctors' phone numbers and protecting the privacy of doctors. At the same time, after obtaining the audio file through virtual outbound calls, the system performs background storage and phonetic conversion. After converting the audio into text, the system automatically extracts useful information based on keywords and saves it to the patient's medical record. Doctors only need to modify and improve it to quickly and accurately complete the writing of an electronic medical record.

[0007] The present invention uses virtual outbound calling means for doctor-patient communication, and a method for converting and extracting key information to quickly generate an initial electronic medical record, making online medical consultations on the Internet timely and efficient under the premise of protecting doctor-patient privacy.

[0008] On the one hand, the present invention provides an online medical consultation system based on virtual outbound calling, including a cloud phone service platform, a communication processing and forwarding module, and an audio storage and processing module.

[0009] The described cloud phone service platform: is a centralized phone service platform built using cloud computing technology. The cloud phone service platform includes two sub-modules: user registration and virtual mobile number allocation

[0010] The user registration sub-module: is used to transmit doctor information into the cloud phone service platform for user registration.

[0011] The virtual mobile number allocation sub-module: generates an encrypted virtual mobile number according to the doctor information transmitted by the user registration sub-module. The specific implementation is as follows:

[0012] Call the API interface of a third-party virtual number service provider through the cloud phone service platform, and transmit the hashed and obfuscated string as a parameter.

[0013] The service provider allocates a temporary virtual number according to the set rules and binds it to the current doctor's consultation session.

[0014] Furthermore, the system performs one-way encryption on the doctor's unique identifier through a hashing algorithm to generate a hash value of a fixed length. The hash value is secondarily obfuscated in combination with a timestamp to ensure the dynamicity and uniqueness of the virtual number.

[0015] The described communication processing and forwarding module: is used to transmit a call request to the cloud phone service platform when the doctor selects to call the patient. The cloud phone service platform makes a call using the corresponding virtual mobile number according to the requested user information. Before requesting the phone service platform, the communication processing and forwarding module needs to perform face recognition verification to ensure the security and privacy of the user, and only after passing the verification can a connection with the phone service platform be established.

[0016] The described audio storage and processing module: is used to save the call audio, convert it into text; and then extract key information according to preset rules to generate an initial electronic medical record, which is provided to the doctor to assist in generating a complete version of the electronic medical record. The specific operations are as follows:

[0017] (1) Phonetic-character conversion and text preprocessing

[0018] Speech recognition technology: Adopt a speech recognition engine based on deep learning to convert call recordings into original text.

[0019] Text cleaning: Denoise the converted text, including deleting duplicate sentences, filtering out modal particles, and correcting punctuation marks to form structured dialogue text.

[0020] (2) Key information extraction rules

[0021] Preset medical knowledge base: The system has a built-in medical knowledge graph, and uses natural language processing (NLP) technology to match key entities in the text.

[0022] (3) Initial electronic medical record generation

[0023] Template filling: Map the extracted key entity information to the corresponding fields of the preset electronic medical record template.

[0024] Structured storage: Generate structured data in JSON or XML format, support seamless docking with the hospital HIS / EMR system to ensure the standardization of medical records.

[0025] Furthermore, provide the obtained initial electronic medical record to the doctor for review and correction.

[0026] Manual intervention mechanism: The initial electronic medical record generated by the system is pushed to the doctor's interface, and the doctor edits, supplements, or deletes the automatically filled content.

[0027] On the other hand, the present invention provides an online consultation method based on virtual outbound calls, including the following steps:

[0028] Step (1) Patient appointment: The patient selects a doctor and makes an appointment through the Internet hospital platform to generate an appointment order. The patient selects a suitable doctor and time through the online consultation system.

[0029] Step (2) Doctor receives the order: After the doctor receives the patient's appointment order in the online consultation system, confirm the appointment reception time. The doctor arranges the appointment reception time according to his own schedule.

[0030] Step (3) Virtual outbound call: During the appointment reception time, the doctor transmits the call request to the cloud phone service platform through the communication processing and forwarding module. The cloud phone service platform uses the corresponding virtual number to make an outbound call to the patient according to the requested user information for telephone communication. The communication processing and forwarding module verifies the doctor's identity through face recognition before transmitting the call request to the cloud phone service platform to ensure the security of the call.

[0031] Step (4) Audio Saving and Processing: After the call ends, the audio saving and processing module of the system automatically saves the call audio, converts it into text, extracts key information according to preset rules, and generates an initial electronic medical record.

[0032] Step (5) Medical Record Generation and Modification: The doctor combines the key information extracted by the system with the actual situation of the patient, modifies and improves the electronic medical record, generates a complete medical record and issues a prescription.

[0033] The beneficial effects of the present invention are as follows:

[0034] First, by introducing the virtual outbound call function, the problem of delayed doctor-patient communication caused by the traditional online consultation relying on instant messaging (IM) tools is completely solved. Doctors and patients can directly communicate by phone through encrypted virtual mobile phone numbers, ensuring real-time interaction between the two parties within the appointed time and avoiding the low diagnosis and treatment efficiency caused by the patient being offline or the message not being responded to in time. Second, the virtual number technology effectively protects the privacy of doctors and patients, avoids the risk of leakage of real contact information, and enhances users' trust in the online consultation system. In addition, the system stores, converts the audio into text and extracts key information from the call audio through automation technology, generating a structured initial electronic medical record template, which greatly reduces the workload of doctors writing medical records manually, improves the consultation efficiency and the accuracy of medical records. At the same time, this technology significantly optimizes the follow-up consultation process for chronic disease patients, reduces the number of times patients go to the hospital, reduces the risk of nosocomial cross-infection, and saves time and economic costs. Finally, the implementation of the present invention further promotes the popularization of the Internet hospital business. By improving the doctor-patient communication efficiency and the diagnosis and treatment experience, it enhances users' satisfaction with online medical services and provides an innovative solution for the sustainable development of smart healthcare.

[0037] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0038] The main purpose of the present invention is to design and develop an online consultation method based on virtual mobile phone numbers for outbound calls. This outbound call function can encrypt and virtualize the mobile phone numbers of patients and doctors, achieving both timely and effective doctor-patient communication and protecting the privacy of doctors and patients. Thus, it improves the communication efficiency between doctors and patients and greatly enhances the satisfaction of doctors and patients in using the Internet hospital software. On this basis, we then perform text conversion on the obtained audio files and extract key information, so as to quickly generate an initial electronic medical record and reduce the workload of doctors in writing medical records. It can play a great role in promoting the online Internet hospital business of physical hospitals. For chronic disease patients, it can greatly reduce the number of hospital visits, not only reducing the risk of cross-infection in the hospital, but also reducing the time cost and the financial cost of coming to the hospital for treatment.

[0039] As Figure 1 shown, an online consultation system based on virtual outbound calls includes a cloud phone service platform, a communication processing and forwarding module, and an audio storage and processing module.

[0040] The said cloud phone service platform: is a centralized phone service platform built using cloud computing technology. The said cloud phone service platform includes two sub-modules: user registration and virtual mobile phone number allocation.

[0041] The said user registration sub-module: is used to transmit doctor information to the cloud phone service platform for user registration.

[0042] The said virtual mobile phone number allocation sub-module: generates an encrypted virtual mobile phone number according to the doctor information transmitted by the user registration sub-module. The specific implementation is as follows:

[0043] Call the API interface of a third-party virtual number service provider (such as an operator or a cloud communication platform) through the cloud phone service platform, and transmit the hashed and obfuscated string as a parameter.
