Technical Field

[0001] The present invention relates to the field of databases, and in particular to a surgical safety verification and control system based on voice interaction technology. Background Art

[0002] Surgical safety verification is a crucial part of the surgical process. Medical staff manually check the verification content, which not only takes a long time to prepare, is tedious and complicated, and consumes a lot of energy, but is also not conducive to information feedback and lacks intelligence and constraints. With the development of medical informatization, electronic surgical safety verification systems have gradually emerged, but there are still problems such as the inability to fully save verification information and the inability to meet real-time on-site verification requirements. Summary of the invention

[0003] In view of the above problems, the present invention is proposed to provide a surgical safety verification and control system based on voice interaction technology that overcomes the above problems or at least partially solves the above problems.

[0004] In order to solve the above technical problems, the embodiments of the present application disclose the following technical solutions:

[0005] A surgical safety verification and control system based on voice interaction technology includes: an intelligent voice interaction module, an intelligent voice database module, a medical record information retrieval module, a surgical safety verification and control module, and a surgical safety verification module; wherein:

[0006] Intelligent voice interaction module, used for voice reminders, voice wake-up and voice recognition by circulating nurses, anesthesiologists and surgeons during surgery;

[0007] An intelligent voice database module, which collects voice information of circulating nurses, anesthesiologists, and surgeons to form feature code entries; it is used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction;

[0008] The medical record retrieval module, after receiving the surgery notification, retrieves the patient's corresponding medical records, test and examination results on the HIS system through voice according to the contents to be checked on the surgery safety checklist;

[0009] The surgical safety inspection and control module is used to control the surgical safety inspection personnel and the inspection time. The surgeon, anesthesiologist, and operating room nurse all wear Bluetooth beacons to achieve real-time positioning and tracking. When the surgeon arrives at the door of the operating room, the Bluetooth base station senses the Bluetooth beacon docking information. The embedded computer at the door of the operating room displays the patient application form for this operating room and shows whether the surgeon is the same as the doctor who arrives at the door of the operating room. The patient can enter the operating room only if the voice broadcast information is correct. After entering the operating room, the digital workstation automatically synchronizes the patient information interface, voice prompts, and the nurse workstation automatically switches to the record interface. The Bluetooth base station in the operating room reads It is obtained that the surgical staff has entered the operating room; the surgical anesthesia time, the operation start time and the exit time are obtained, and corresponding events are generated according to the surgical anesthesia time, the operation start time and the exit time, and voice reminders are given according to the corresponding events, and the three-party verification of the surgeon, the anesthesiologist and the operating room nurse is started and switched to the safety verification interface, the safety verification interface is locked, the voice interaction system is started, and the verification content is put on the surgical field screen, and the three parties conduct safety verification item by item, and after passing the safety verification, each item is confirmed and an electronic signature is formed. If the safety verification is not performed, the next step of operation will not be possible on the hand numbness system;

[0010] The surgical safety verification module is used by circulating nurses, anesthesiologists, and surgeons to conduct safety verification of the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the patient leaves the operating room, to ensure the patient's correct identity, correct surgical site, and correct surgical method during the operation.

[0011] Further, the intelligent voice interaction module includes a voice device and a first processor;

[0012] The voice device is arranged at different positions in the operating room; the voice device is used to receive the voice signal of the medical staff and send it to the first processor; the voice device also pre-stores the corresponding event of the operation and the corresponding voice reminder content, and is used to receive the voice reminder automatically started by the digital device in the operating room after the hand numbness workstation obtains the corresponding event;

[0013] The first processor is used to receive the voice signal of the medical staff sent by the voice device, and process the voice signal so that the mobile terminal device and the digital equipment in the operating room can understand the text and retrieve the medical record information to identify and check whether the items are correct.

[0014] Furthermore, the intelligent voice interaction module is used for voice reminders and voice wake-ups by circulating nurses, anesthesiologists, and surgeons during the operation; specifically, after the hand anesthesia workstation obtains the corresponding event, the digital equipment in the operating room automatically starts voice reminders; when the surgeon has washed his hands, put on surgical gowns and sterile gloves and is unable to sign, the digital equipment is awakened by voice, and the equipment is awakened from sleep mode and responds, meeting the voice dialogue needs and conducting surgical safety checks.

[0015] Furthermore, the intelligent voice interaction module is used for voice recognition by circulating nurses, anesthesiologists, and surgeons during operations, specifically including: receiving voice information, having conversations with personnel involved in safety checks, processing natural language information through computers, enabling mobile terminal devices and digital equipment in operating rooms to understand text and retrieve medical record information to identify and verify whether the items are correct.

[0016] Furthermore, the intelligent voice database module is used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction; wherein, the intelligent voice database stores a large amount of voice data for the training and optimization of voice recognition and voice synthesis functions;

[0017] Medical staff can use voice to retrieve the verification data corresponding to a patient and display the verification data on the display screen. Medical staff do not need to verify the data by flipping through paper medical records, which improves the efficiency and speed of verification and greatly reduces the complicated workflow of medical staff in the operating room to manually verify large amounts of data. In the operating room, voice commands can be used to switch and record surgical videos, and turn digital equipment on or off, thereby improving medical quality and work efficiency.

[0018] Furthermore, when the medical record review module receives the surgery notification signal, it reviews the patient information and medical record data through the HIS system according to the content on the safety checklist; the specific methods include: retrieving the surgery consent form and the safety checklist, and having the reviewer repeat the surgery name and surgery site to determine whether the surgery name and site are correct; retrieving the medical imaging examination results to determine whether the surgery site and left and right sides are correct; retrieving the test results to determine whether the infection screening items are checked correctly, and automatically generating invisible answers. When implementing the surgery safety check, voice recognition is used to determine whether the surgery staff responds to the safety check items correctly.

[0019] Furthermore, the specific working methods of the surgical safety check control module include: after determining that the safety check has not been performed before anesthesia after the safety check personnel arrives at the operating room, the mobile terminal of the hand anesthesia workstation automatically switches to the safety check interface before anesthesia implementation, and automatically restricts the filling of surgery and anesthesia records. If there are missing items that have not been checked, the system will give a reminder and need to check each item one by one. If this check is not completed, the surgical staff will not be allowed to perform the safety check before the operation begins.

[0020] Furthermore, the specific working method of the surgical safety verification control module also includes: the mobile terminal of the hand numbness workstation and the digital equipment display screen in the operating room automatically switch to the safety verification interface before the operation, automatically restrict the filling of the operation start time and related records, and if there are missed items that have not been checked, a reminder will be given and they need to be checked item by item. If this check is not completed, the surgical staff will not be allowed to perform the safety check operation before the patient leaves the room.

[0021] Furthermore, the specific working method of the surgical safety verification and control module also includes: if the safety check is not carried out before the patient leaves the room, the mobile terminal of the hand numbness workstation automatically switches to the safety check interface before the patient leaves the room, and automatically limits the filling of the patient's departure time. If there are missing items that have not been checked, the system will give a reminder and need to check them item by item; if this check is not completed, the surgical staff will not be allowed to proceed to the next system operation and cannot submit various record sheets; after passing the safety check, each item is confirmed and an electronic signature is formed, or the system confirms through intelligent voice recognition that the safety check is completed item by item before the operation can be performed.

[0022] Furthermore, the surgical safety verification module is used for circulating nurses, anesthesiologists, and surgeons to conduct safety verification of the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the surgical patient leaves the operating room. Specific methods include: using intelligent voice reminders or double-clicking the start time to automatically switch to the safety verification interface, which can start voice broadcasts to remind the operator to step through the surgical safety verification process; during the safety check before the operation, because the surgeon has already washed his hands, put on surgical gowns and sterile gloves and cannot sign, the voice recognition function can be used to judge the operator's instructions and execute the next process. The process points are irreversible, and the next node cannot be entered if the previous node is not completed. Until the surgical safety check is completed, the hand anesthesia system workstation continues to be used, the digital surgical equipment display screen is started, and the operator begins the surgical operation. If the verification is not completed before the patient leaves the operating room, the end time of the operation cannot be generated, and the record form cannot be completed for leaving the room for handover, and the system will automatically broadcast a voice reminder.

[0023] The beneficial effects of the above technical solution provided by the embodiment of the present invention include at least:

[0024] The present invention discloses a surgical safety verification and control system based on voice interaction technology, comprising: an intelligent voice interaction module, an intelligent voice database module, a medical record information retrieval module, a surgical safety verification and control module, and a surgical safety verification module; wherein: the intelligent voice interaction module is used for voice reminders, voice awakening, and voice recognition of circulating nurses, anesthesiologists, and surgeons during surgery; the intelligent voice database module, which collects voice information of circulating nurses, anesthesiologists, and surgeons to form feature code input; and is used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction; the medical record information retrieval module, after receiving the surgical notification form, retrieves the corresponding medical records, test and examination results of the patient on the HIS system through voice according to the contents to be verified on the surgical safety verification form;

[0025] The surgical safety inspection and control module is used to control the surgical safety inspection personnel and the inspection time. The surgeon, anesthesiologist, and operating room nurse all wear Bluetooth beacons to achieve real-time positioning and tracking. When the surgeon arrives at the door of the operating room, the Bluetooth base station senses the Bluetooth beacon docking information. The embedded computer at the door of the operating room displays the patient application form for this operating room and shows whether the surgeon is the same as the doctor who arrives at the door of the operating room. The patient can enter the operating room only if the voice broadcast information is correct. After entering the operating room, the digital workstation automatically synchronizes the patient information interface, voice prompts, and the nurse workstation automatically switches to the record interface. The Bluetooth base station in the operating room reads It is obtained that the surgical staff has entered the operating room; the surgical anesthesia time, surgery start time and exit time are obtained, and corresponding events are generated according to the surgical anesthesia time, surgery start time and exit time. Voice reminders are given according to the corresponding events, and a three-party check between the surgeon, anesthesiologist and operating room nurse is started and the switch is made to the safety check interface. The safety check interface is locked, the voice interaction system is started, and the check content is put on the surgical field screen. The three parties perform a safety check item by item, and after passing the safety check, each item is confirmed and an electronic signature is formed. If the safety check is not performed, the next step cannot be performed on the surgical system.

[0026] The surgical safety verification and control system based on voice interaction technology proposed in the present invention effectively solves the problems existing in the existing surgical safety verification system through intelligent, efficient and accurate technical means, improves the compliance and accuracy of surgical safety verification, and ensures the surgical safety of patients.

[0034] An intelligent voice database module, which collects voice information of circulating nurses, anesthesiologists, and surgeons to form feature code entries; it is used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction;

[0035] The medical record retrieval module, after receiving the surgery notification, retrieves the patient's corresponding medical records, test and examination results, etc. on the HIS system through voice according to the contents to be checked on the surgery safety checklist;

[0036] The surgical safety verification control module is used to obtain the surgical anesthesia time, the surgical start time and the time to leave the room, generate corresponding events according to the surgical anesthesia time, the surgical start time and the time to leave the room (the automatic extraction of this time is set to be unmodifiable to avoid not completing the verification within the specified time), make voice reminders according to the corresponding events, start the three-party verification and switch to the safety verification interface, and confirm each item after passing the safety verification and form an electronic signature;

[0037] The surgical safety verification module is used by circulating nurses, anesthesiologists, and surgeons to conduct safety verification of the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the patient leaves the operating room, to ensure the patient's correct identity, correct surgical site, and correct surgical method during the operation.

[0038] In this embodiment, the intelligent voice interaction module includes a voice device and a first processor;

[0039] The voice device is arranged at different positions in the operating room; the voice device is used to receive the voice signal of the medical staff and send it to the first processor; the voice device also pre-stores the corresponding event of the operation and the corresponding voice reminder content, and is used to receive the voice reminder automatically started by the digital device in the operating room after the hand numbness workstation obtains the corresponding event;

[0040] The first processor is used to receive the voice signal of the medical staff sent by the voice device, and process the voice signal so that the mobile terminal device and the digital device in the operating room can understand the text and retrieve the medical record information to identify and check whether the items are correct. In this embodiment, the digital device in the operating room includes at least an information integration system, a digital control system, a rich media medical record recording system, etc., wherein the information integration system can combine the medical imaging system (such as HIS, PACS, etc.) in the operating room with the medical display to provide doctors with comprehensive medical information and patient information; the digital control system can organically integrate surgical equipment, such as endoscopic equipment, conventional equipment in the operating room (lights, beds, electric knives, etc.), panoramic cameras in the operating room, surgical field cameras, image management equipment, air conditioners and lights, and the circulating nurses control them through the system; rich media medical record recording system. The system can automatically identify effective video signals, automatically collect video images, generate electronic medical records, upload them to the cloud space, and store them in the hospital medical record database. After the operation, the authorized surgeon can download and edit them at any terminal in the local area network, reducing the workload of the doctor.

[0041] The intelligent voice interaction module is used for voice reminders and voice wake-ups for circulating nurses, anesthesiologists, and surgeons during the operation. Specifically, after the hand anesthesia workstation obtains the corresponding event, the digital equipment in the operating room automatically starts voice reminders. When the surgeon has washed his hands, put on surgical gowns and sterile gloves and is unable to sign, the digital equipment is awakened by voice, such as: "Xiao Ai, Xiao Ai, start the pre-operative safety check", and the device is awakened from the sleep state and responds to meet the voice dialogue needs and conduct a surgical safety check.

[0042] In this embodiment, the intelligent voice interaction module is used for voice recognition by circulating nurses, anesthesiologists, and surgeons during the operation, specifically including: receiving voice information, having conversations with personnel involved in the safety check, processing natural language information through computers, enabling mobile terminal devices and digital equipment in the operating room to understand text and retrieve medical record information to identify and verify whether the items are correct.

[0043] Specifically, to receive voice information, the natural language information is processed by the computer, so that the mobile terminal equipment and the digital equipment in the operating room can understand the text and retrieve the medical record information to identify and check whether the items are correct. This involves multiple technical fields, including speech recognition, natural language processing (NLP), and the integration of medical information systems. Among them, speech recognition technology converts voice signals into corresponding text or commands through machine recognition and understanding processes. Natural language processing (NLP) technology aims to enable computers to understand, comprehend and generate human language. It simulates human language understanding and analysis capabilities to achieve tasks such as human-computer interaction, information extraction, and semantic analysis. The medical information system integrates the hospital servers deployed on the intranet, including mobile doctor workstation proxy servers, electronic medical record servers, etc. The medical voice cloud server deployed on the extranet ensures the secure communication of internal and external network servers through SSL VPN and other methods.

[0044] In this embodiment, the intelligent voice database module is used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction; wherein, the intelligent voice database stores a large amount of voice data for training and optimization of voice recognition and voice synthesis functions; specifically:

[0045] Medical staff can use voice to retrieve the verification data corresponding to a patient and display the verification data on the display screen. Medical staff do not need to verify the data by flipping through paper medical records, which improves the efficiency and speed of verification and greatly reduces the complicated workflow of medical staff in the operating room to manually verify large amounts of data. In the operating room, voice commands can be used to switch and record surgical videos, and turn digital equipment on or off, thereby improving medical quality and work efficiency.

[0046] In this embodiment, when the medical record review module receives the surgery notification signal, it reviews the patient information and medical record data through the HIS system according to the content on the safety checklist; the specific method includes: retrieving the surgery consent form and the safety checklist, and the reviewer repeating the surgery name and surgery site to determine whether the surgery name and site are correct; retrieving the medical imaging examination results to determine whether relevant imaging data are needed; retrieving the test results to determine whether the infection screening items are checked correctly, and automatically generating invisible answers. When implementing the surgery safety check, voice recognition is used to determine whether the surgery staff responds to the safety check items correctly.

[0047] In this embodiment, the medical record data retrieval module includes a voice recognition module and a second processor; the voice recognition module is used to recognize the contents on the surgical consent form and the safety checklist, obtain the surgical name and surgical site on the surgical consent form and the safety checklist repeated by the checker, and send the surgical name and surgical site to the processor;

[0048] The second processor is used to receive the operation name and operation site recognized by the voice recognition module, and retrieve the medical imaging results to determine whether relevant imaging data is needed; retrieve the test results to determine whether the infection screening items are checked correctly, and automatically generate invisible answers.

[0049] In this embodiment, the specific working method of the surgical safety check control module includes: after determining that the safety check has not been performed before anesthesia after the safety check personnel arrives at the operating room, the mobile terminal of the hand anesthesia workstation automatically switches to the safety check interface before anesthesia implementation, and automatically restricts the filling of surgery and anesthesia records. If there are missing items that have not been checked, the system will give a reminder and need to check each item one by one. If this check is not completed, the surgical personnel will not be allowed to perform operations without a safety check before the start of the operation.

[0050] In some preferred embodiments, the specific working method of the surgical safety verification control module also includes: the mobile terminal of the hand numbness workstation and the digital equipment display screen in the operating room automatically switch to the safety verification interface before the operation, automatically restrict the filling of the operation start time and related records, and if there are missing items that have not been checked, a reminder will be given and they need to be checked item by item. If this check is not completed, the surgical staff will not be allowed to perform safety checks before the patient leaves the room.

[0051] In some preferred embodiments, the specific working method of the surgical safety verification control module also includes: if the safety check is not performed before the patient leaves the room, the mobile terminal of the hand numbness workstation automatically switches to the safety check interface before the patient leaves the room, and automatically limits the filling of the patient's departure time. If there are missing items that have not been checked, the system will give a reminder and need to check them item by item; if this check is not completed, the surgical staff will not be allowed to proceed to the next system operation and cannot submit various record sheets; after passing the safety check, each item is confirmed and an electronic signature is formed, or the system confirms through intelligent voice recognition that the safety check is completed item by item before the surgical safety inspection can be carried out.

[0052] In this embodiment, the definition of surgical safety check is: the surgeon, anesthesiologist, and circulating nurse conduct a safety check on the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the surgical patient leaves the operating room, to ensure the patient's correct identity, correct surgical site, and correct surgical method during the operation. The relevant medical management system of national health institutions clearly stipulates that all operations must undergo a surgical safety check. The "three parties" of the surgical safety check: anesthesiologists, surgeons, and circulating nurses; the timing of the check: check before anesthesia starts, check before surgery starts, and check before the patient leaves the operating room. When the operator proceeds to the start of anesthesia, before surgery starts, and before the patient leaves the operating room, the system obtains the corresponding event, issues a voice reminder to start the three-party check, and automatically switches to the safety check item. The system has electronic verification forms. The circulating nurses, anesthesiologists, and surgeons confirm the verification items. The system will automatically identify whether the verification is completed, whether the verification content is correct, and whether the verification personnel are the main verification personnel. If there are missing items that have not been verified, and the verification items are inconsistent with the patient medical record information in the HIS system, the verification is incorrect, and the three-party verification personnel are incorrect (the surgeon has not arrived in the operating room and is replaced by an intern or other personnel. After the surgeon arrives in the operating room, he wears a Bluetooth wristband, which locates the location of the medical staff and shows whether he has arrived in the operating room). The system will give an early warning reminder. If this verification is not completed, the system will not allow the operator to proceed to the next system operation.

[0053] In this embodiment, the surgical safety verification module is used for circulating nurses, anesthesiologists, and surgeons to conduct safety verification of the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the surgical patient leaves the operating room. The specific method includes: using intelligent voice reminders or double-clicking the start time to automatically switch to the safety verification interface, which can start voice broadcasting to remind the surgeon to gradually perform the surgical safety verification process; during the safety verification before the operation begins, because the surgeon has already washed his hands and put on surgical gowns and sterile gloves and cannot sign, the voice recognition function can be used to judge the surgeon's instructions and execute the next process. The process point is irreversible, and the next node cannot be entered if the previous node is not completed until the surgical safety verification is completed, the hand anesthesia system workstation continues to be used, the digital surgical equipment display screen is started, and the surgeon begins the surgical operation. If the patient does not complete the verification before leaving the operating room, the end time of the operation cannot be generated, and the record sheet cannot be completed for leaving the room for handover, and the system will automatically broadcast a voice reminder. After each safety verification opportunity is verified correctly, the system automatically generates an electronic signature of the verification personnel, and the entire process ends.

[0054] The present embodiment discloses a surgical safety verification and control system based on voice interaction technology, including: an intelligent voice interaction module, an intelligent voice database module, a medical record information retrieval module, a surgical safety verification and control module, and a surgical safety verification module; wherein: the intelligent voice interaction module is used for circulating nurses, anesthesiologists, and surgeons to perform voice reminders, voice wake-up, and voice recognition during the operation; the intelligent voice database module, which collects voice information of circulating nurses, anesthesiologists, and surgeons to form feature code entries; used to realize the linkage between the intelligent voice database and the hospital HIS system to complete data interaction; the medical record information retrieval module is used to, when receiving the surgical notification signal, The contents on the full verification form are reviewed through the HIS system for patient information and medical records; the surgical safety verification control module is used to obtain the surgical anesthesia time, surgical start time and exit time, and generate corresponding events based on the surgical anesthesia time, surgical start time and exit time, and give voice reminders based on the corresponding events, and start a three-party verification and switch to the safety verification interface.

When implementing the surgery safety check, voice recognition determines whether the surgeon's responses to the safety check items are correct.

3. A surgical safety verification and control system based on voice interaction technology as described in claim 1, characterized in that: The surgical safety verification module is used by circulating nurses, anesthesiologists, and surgeons to conduct safety verification of the patient's basic information and surgical information before anesthesia is implemented, before the operation begins, and before the surgical patient leaves the operating room. Specific methods include: using intelligent voice reminders or double-clicking the start time to automatically switch to the safety verification interface, which can start voice broadcasts to remind the surgeon to step through the surgical safety verification process; during the safety check before the start of the operation, because the surgeon has already washed his hands, put on surgical gowns and sterile gloves and cannot sign, the voice recognition function can be used to judge the surgeon's instructions and execute the next process. The process points are irreversible, and the next node cannot be entered if the previous node is not completed. Until the surgical safety check is completed, the hand anesthesia system workstation continues to be used, the digital surgical equipment display screen is started, and the surgeon begins the surgical operation. If the verification is not completed before the patient leaves the operating room, the end time of the operation cannot be generated, and the record form cannot be completed for leaving the room for handover. The system will automatically broadcast voice reminders.

4. A surgical safety verification and control system based on voice interaction technology as claimed in claim 1, characterized in that: The intelligent voice interaction module is also used for voice recognition by circulating nurses, anesthesiologists, and surgeons during the surgical safety check, specifically including: receiving voice information, having conversations with the personnel involved in the safety check, processing natural language information through a computer, so that mobile terminal devices and digital equipment in the operating room can understand text and retrieve medical record information to identify and verify whether the items are correct.
