[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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 of 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.

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0024] The present invention will be further described below in conjunction with the drawings and specific embodiments, but it is not limited to the present invention.

[0025] The present invention includes a 5G sliced private network applicable to wireless digital signal transmission in the operating room, comprising: a user function plane unit 1, connected to an external 5G core network and connected to the in-hospital informatization system 2 through a 5G edge computing interface; a baseband processing unit 3, connected to the user function plane unit 1 and the external 5G core network, and converting network signals into baseband digital signals; a hub unit 4, connected to the baseband processing unit 3 and accessing the operating room through a wired connection passing through the operating room shielding layer 9; a radio frequency remote unit, arranged in the operating room, connected to the hub unit 4, and providing 5G mobile network coverage in the operating room; a 5G data transmission unit, arranged in the operating room, connected to medical devices through a wired connection and connected to the radio frequency remote unit through a 5G mobile network; the 5G mobile network deployed based on the user function plane unit 1, the baseband processing unit 3, the hub unit 4, and the radio frequency remote unit is provided with a first slice network and a second slice network, wherein the first slice network is used for external 5G mobile network communication, and the second slice network is used for in-hospital data communication; a programmable logic controller 20, connected to the second sliced private network.

[0026] It should be noted that the 5G sliced private network, that is, the second sliced private network, refers to setting the network between the radio frequency remote unit, the hub unit 4, the baseband processing unit 3, and the user function plane unit 1 as an in-hospital private network through 5G slicing technology. The data in the private network, including the data collected by sensors in the operating room, equipment status, video streams, as well as in-hospital electronic information, electronic medical records, laboratory reports, imaging data, etc., are only communicated and exchanged within the private network without passing through external gateway or routing devices, meeting the security requirement that medical data does not leave the hospital. At the same time, this setting can be deployed on the operator's network, only dividing the data stream at the service layer. On the premise of ensuring security, better communication effects and subsequent maintenance services can be obtained, improving the overall reliability and security of the system, and also facilitating subsequent upgrades and updates; when business needs, an external network can also be accessed through a separately set routing interface, reserving space for external data interaction and remote medical treatment.

[0027] Specifically, as Figure 1 shown, three radio frequency remote units are arranged in the operating room, namely a first radio frequency remote unit 10, connected to a medical device 16 and an operating environment control device 21 through a 5G data transmission unit 12, for meeting low-latency requirements; a second radio frequency remote unit 11, connected to an Internet of Things sensor 13 and an Internet of Things controller 19, for meeting high-frequency large-concurrency low-data-volume requirements; a third radio frequency remote unit 17, connected to a display unit 14 and a video monitoring device 18, for meeting high-bandwidth requirements.

[0028] Furthermore, the radio frequency remote units 10, 11, 17 are arranged in the operating room, shortening the distance from the access devices and ensuring the wireless network coverage within the operating room shielding layer.

[0029] It should be noted that the first radio frequency remote unit 10, the second radio frequency remote unit 11, and the third radio frequency remote unit 17 respectively corresponding to different requirements are only taken as an example. In actual situations, the same radio frequency remote unit can simultaneously meet the requirements of low latency, high-frequency large concurrency and low data volume, and high bandwidth through network slicing technology and QoS (Quality of Service) technology.

[0030] Furthermore, in the prior art, in the operating room, due to the installation of a large number of intraoperative examination devices with strong electromagnetic interference such as DSA, CT, MRI, etc., and the reflection interference of the electromagnetic signal generated by the shielding layer of the operating room with an electromagnetic shielding layer, traditional mobile communication devices cannot achieve good performance. In this embodiment, the radio frequency remote units 10, 11, 17 and the 5G data transmission unit 12, the Internet of Things sensors 13 and the Internet of Things controller 19, etc. are specially designed and have obtained good ECM performance, and can achieve the expected performance in the operating room scenario.

[0031] In a preferred embodiment, the 5G data transmission unit 12 is connected to the medical device 16 and the surgical environment control device 21 through the MQTT / MODBUS protocol, the RS-232 serial port, the RS-485 serial port and the bidirectional parallel port.

[0032] Specifically, through the 5G data transmission unit 12, the original cumbersome wired communication lines can be omitted on the premise of ensuring the performance of the medical device 16, the maintenance cost can be reduced, and it is convenient for the subsequent access of updated devices.

[0033] Furthermore, the Internet of Things sensors 13 include temperature and humidity sensors, differential pressure sensors, air quality sensors, air conditioner operating state sensors, fresh air system sensors and environmental monitoring sensors.

[0034] In a preferred embodiment, the Internet of Things sensors 13 and the Internet of Things controller 19 are connected to the programmable logic controller 20 through the second slice network; the Internet of Things sensors 13, the Internet of Things controller 19 and the programmable logic controller 20 are also connected to the in-hospital information system 2 through the second slice network.

[0035] Furthermore, the above radio remote units 10, 11, 17, as physical nodes carrying the SGW (Serving GW), are used for the access of the Internet of Things sensors 13 and the Internet of Things controller 19; on the PGW (Packet Data Network Gateway) side, the programmable logic controller 20 accesses the second slice private network through wired means, and the wired access methods include but are not limited to gateway devices or routing devices. On the SGW side, by setting the corresponding software API interfaces, the data of the Internet of Things sensors 13 and the Internet of Things controller 19 can be effectively obtained and sent to the PGW side, and then the data is sent into the programmable logic controller 20 and the in-hospital information system 2 through the corresponding software API interfaces. Subsequently, after the in-hospital information system 2 processes the data through big data analysis and artificial intelligence programs, corresponding instructions are sent to the programmable logic controller 20, and the programmable logic controller sends corresponding instructions to the PGW through the API interface, and forwards them to the SGW side through the second slice network, thereby realizing the control of the Internet of Things sensors 13 and the Internet of Things controller 19.

[0036] Specifically, a single SGW can correspond to multiple Internet of Things sensors 13, and at the same time, a single PGW can also correspond to multiple programmable logic controllers 20. Connecting multiple Internet of Things sensors 13 to a single gateway interface SGW can shorten the construction time and reduce the later maintenance cost. At the same time, connecting multiple programmable logic controllers 20 in a single PGW gateway interface can reserve space for subsequent access to new digital devices without the need to remove the original Internet of Things devices, reducing the overall system upgrade cost and enabling the system as a whole to perform better than expected in the future.

[0037] In a preferred embodiment, the in-hospital information system 2 includes a medical image management system, a laboratory management system, a hospital information system, an operating room integrated data processing system, and an operating room environment control system 22.

[0038] Specifically, the operation environment control system 22 included in the in-hospital information system 2 is connected to the operation environment control device 21 set in the operating room through the second slice private network, and controls the operation environment control device 21 according to the relevant information collected by the in-hospital information system 2, including the information collected by the Internet of Things sensor 13, the air quality, temperature, and humidity in the operating room, the operation information fed back by the medical device 16, and the instructions issued by the operator through the Internet of Things controller 19. By setting the operation environment control system 22 in the in-hospital information system 2, the information collected from the medical device 16, the operation environment control device 21, the Internet of Things sensor 13, the Internet of Things controller 19, and the video monitoring device 18 can be effectively integrated, analyzed based on the artificial intelligence program, and the automatic control of the operation environment control device 21 can be realized through the programmable logic controller 20, thereby improving the efficiency and accuracy of the operation room environment control, reducing the use of manpower and the cost of subsequent maintenance, and reserving an upgrade space for integrating more digital devices in the future.

[0039] In a preferred embodiment, the user function plane unit 1 is connected to the in-hospital information system 2 through the 5G edge computing interface, accesses the hospital information system, laboratory management system, and picture archiving and communication system in the hospital, and forwards the in-hospital information data to the operating room.

[0040] Specifically, the user function plane unit 1 is connected to the in-hospital information system 2 through the 5G edge computing interface, receives and forwards the hospital information 5, laboratory data 6, medical images 7, and electronic medical records 8 to the operating room and displays them on the display unit 14.

[0041] In a preferred embodiment, the operation room data comprehensive processing platform 15 analyzes and processes the data of the Internet of Things sensors and the in-hospital information data through the artificial intelligence program and the big data training set.

[0042] Furthermore, the operation room comprehensive data processing system 15 integrates and processes the data collected by the Internet of Things sensor 13 and the 5G data transmission unit 12, the instructions issued by the Internet of Things controller 19, and the in-hospital data obtained through the in-hospital information system 2, and controls the Internet of Things sensor 13 and the operation environment control device 21 through the programmable logic controller 20.

[0043] Specifically, the integrated operating room data processing system 15 uniformly controls the Internet of Things sensors 13 and the operating room environment control devices 21, which can effectively cross-compare and uniformly process the collected data, including but not limited to: the information collected by the Internet of Things sensors 13, the air quality, temperature, and humidity in the operating room, the surgical information feedback by the medical devices 16, and the instructions issued by the operator through the Internet of Things controller 19, to obtain more comprehensive data for the artificial intelligence program to process. By increasing the types and quantities of the collected data, better control effects can be achieved, automatically adjusting the operating room environment according to the surgical type and surgical process, and controlling multiple operating room environment control devices 21 in the operating room to improve the overall working efficiency of the diagnosis and treatment system in the operating room and achieve better treatment effects.

[0044] Specifically, as Figure 3 shown, the software architecture of the operating room data integrated processing platform 15 can be divided into four layers.

[0045] The first layer is the device and network management layer L1, including access, monitoring, and signaling docking, providing the connection and management and control of the physical layer and the link layer;

[0046] The second layer is the service data access layer L2, which is used to receive and integrate various types of service data, including in-hospital information system data 201, including hospital information systems, laboratory management systems, and medical imaging management and archiving systems; Internet of Things sensor data 202, including room temperature, air pressure, air quality, etc.; and device status data 203, including the working conditions of air conditioners and fresh air equipment, and the status of the operating room environment control system.

[0047] The third layer is the data processing layer L3, which standardizes and analyzes the service data and provides functions such as data storage, data interaction, big data, artificial intelligence, streaming media, and image analysis;

[0048] The fourth layer is the application layer L4, including control applications 401, such as policy analysis, logic control, status prediction, and notification and warning; display applications 402, such as multi-screen interaction, command cabins, web applications, augmented reality, and virtual reality, etc.;

[0049] At the same time, it also provides external application docking functions 403 through application programming interfaces, software development toolkits, virtual desktops, and converged media.

[0050] Specifically, by setting up the software platforms of L1-L4 layers, the control of physical network devices can be effectively achieved on the same processing platform, improving the reliability and security of system connections; by setting up an integrated processing platform with a large number of API interfaces, the data collected by numerous Internet of Things sensors 13, 5G data transmission units 12 and video surveillance devices 18 can be integrated and processed, improving the availability of data and the data interaction efficiency among various modules within the system, and enhancing the timeliness of the system; and the business data is further standardized at the L3 layer. Through the integration of multi-sensor data, and by means of methods such as cross-comparison of multi-sensor data, big data record comparison, and artificial intelligence program analysis, the multi-sensor data is processed, and the data with relatively large deviation values is eliminated and the corresponding fault information is reported, facilitating subsequent maintenance work. It can also give corresponding suggestions to the personnel in the operating room through artificial intelligence program analysis, improving medical efficiency.

[0051] Furthermore, by reserving a large number of API interfaces in the software platform, it is convenient to add new digital devices during subsequent maintenance and upgrade processes, and new digital devices can be integrated on the premise of not making major changes to the original software platform, enhancing the overall life cycle and maintainability of the system.

[0052] In a preferred embodiment, the second slice network and the first slice network use different frequency bands for network coverage.

[0053] Specifically, through the coordination of the operator, the 5G private network base stations within the hospital and the external 5G mobile network select different frequency bands for network coverage, and a network verification program is set up to prohibit non-hospital devices from accessing the second slice network through information such as MAC address, device status, and security token, ensuring the communication security within the hospital.

[0054] In a preferred embodiment, the data processed by the operating room integrated data processing platform 15 is displayed on the display unit 14 in the operating room through a data interface.

[0055] Specifically, hospital information 5, laboratory data 6, medical images 7, and electronic medical records 8 are displayed on the data interface; information displayed by medical devices 16, such as intraoperative examination images, vital sign monitoring, parameters of the artificial extracorporeal circulation system, anesthesia and fluid infusion data, etc.; and information such as temperature and humidity, differential pressure, air quality, and device status collected by the Internet of Things sensors 13. Also, corresponding alarm information and external communication data are automatically displayed based on the artificial intelligence program. Displaying the above information intuitively and clearly through a unified data interface can avoid the situation in the prior art where multiple medical devices are placed far apart, resulting in relevant operators not being able to conveniently grasp the overall situation in the operating room, greatly improving work efficiency; and through the 5G access technology, it avoids the limitations in viewing angles and installation methods and the inconvenience of subsequent maintenance caused by the large amount of wiring required for traditional monitors. It can also conveniently connect MR and AR devices through the 5G access technology and display relevant images, realizing head-up display-free, and clearly and intuitively projecting the corresponding data and the lesion conditions obtained by examination devices such as nuclear magnetic resonance, ultrasound, and X-ray into the eyes of the surgeon, the first assistant, and the second assistant, improving work efficiency.

[0056] In a preferred embodiment, the hub unit 4 is used to convert optical fiber signals into electrical signals and power the remote radio unit through the local area network power supply port and the POE port, effectively avoiding the trouble of having to set up multiple corresponding power lines for traditional network devices and the limitation of having to be set beside the AC power interface, and being able to better set up the remote radio unit from a performance perspective, ultimately achieving full-range 5G signal coverage in the operating room environment.

[0057] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that any equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
