Architecture
The system is based on the TCP/IP architecture transmission technology of the local area network, realizing bidirectional calling and intercom between the medical terminal of the ward nurse station, the terminal at the entrance of the ward, and the bedside terminal. The nurse station medical terminal, duty extension, ward entrance terminal, and bedside terminal can all be set with independent IP addresses for independent management on the system platform.
The system platform is built using the B/S model, Web browsing does not require the installation of controls, and can be accessed remotely through a local area network. By logging into the system management platform with department account permissions, it is possible to achieve unified management of devices in branches and other institutions located far away from each other or in different regions.

Network composition
Network platform: It can be a hospital's local area network, and the system requires a bandwidth of 10Mbps at the center exit and 1Mbps at the terminal node. The switch in the figure supports layer 2 switching.
Smart ward nursing call server: used to receive information from HIS interface servers, doctors, nurses, ward hosts, mobile phones, and wearable devices, and generate the latest medical and nursing information in real time.
HIS interface server: It is an interface machine that communicates with the hospital's existing HIS system. It can be designed in a dual network mode to ensure the security of the HIS system. Generally, it is located on the same server as the nursing call server in the smart ward.
Patient information display screen: used to display information related to beds in the ward, and provide relative color block reminders for alarm situations, while accompanying medical duty situations and arrangements. It can display the number of inpatients, available beds, nursing level, nursing handover status, on duty medical staff, and important messages in the department ward, completely replacing the traditional bulletin board;
Doctor on duty management terminal: Install a doctor's end management software, which makes it convenient for doctors to check the patient's medical status and issue medical instructions, and install it in the doctor's office.
Nurse Station Management Terminal: Install nurse management software, which makes it convenient for the nurse station to query patient medical status and process medical instructions. At least one nurse management terminal needs to be installed on each nurse station.
Nurse Watch: A personal watch for nurses, used to receive all or part of call information for specific beds and provide relative responses.
Corridor information screen: can display status information such as hospital bed calls, emergency calls, infusion alarms, and nursing reinforcements. When there is no call information, other information released by the system time can be displayed.
Ward entrance call terminal: used to display ward information and comprehensive information of hospital beds in the ward. It can be connected to the door light, and according to the alarm status of the hospital call terminal, bathroom call, and infusion alarm, the door light flashes in relative colors to prompt an alarm.
Bed care call terminal: used to display patient information on the bed and provide relative reminders of the corresponding patient's condition. It can be connected to the emergency alarm in the bathroom and extended to the bedside for use.
Data layer: used for collecting and summarizing hospital information.
Application layer: Implement the organization, scheduling and control of data and content, and receive interactive triggering events from doctors and nurses to generate information display lists.
Presentation layer: The network terminal parses the received data and generates display data.

System composition
1 The IP call system can be connected to the inpatient system through software interfaces, and real-time patient registration information such as name, visit number, medical record number, inpatient room, bed, etc. can be obtained from the inpatient system to avoid duplicate entry, synchronize data refresh, and fully utilize the existing HIS system.
2. Based on the distribution of inpatients, we set up a medical desk in each area to manage information for all wards in this area; By using the patient information display screen, all wards and medical staff on duty in the area can be visually viewed at the nurse station; The call terminal at the entrance of the ward, the nursing call terminal at the hospital bed, the nurse station management terminal, and the emergency alarm in the bathroom, three color door lights, and corridor information screen form information guidance to provide medical staff with ward information prompts; At the same time, nurse watches and apps can be configured as personal reminders.
3. You can log in to the webpage backend at any time within the network to achieve functions such as equipment management, hospital staff information management, department patient information management, nursing level management, admission and exit management, voice broadcasting, software settings, fault self inspection, and application upgrades.
4. Reserve open interfaces that can be integrated and expanded with hospital HIS or other systems.

Each ward has a ward management center (nurse station), and large wards can set up multiple medical and nursing hosts at the nurse station to facilitate high-quality services and work efficiency.
In the construction of ward networking, high-quality network switches are used to achieve digital switching, transmission and other functions in the ward.
In terms of transmission materials, it is advisable to use fiber optics and fiber optic transceivers for long-distance connections, and use Category 5 cables for transmission within the ward.
According to the actual situation on site, each entrance and exit of the ward can be equipped with a terminal device for managing the entrance of the ward, making it easy for visitors to confirm their identity through visual intercom with the nurse station. Medical staff can enter and exit through card swiping.

Function Introduction
The Mingke IP medical intercom system consists of 25 modules, with a layout structure divided into: nurse station, doctor's office, ward corridor, and inside the ward. Each area can be equipped with complete information equipment, including but not limited to: computer, nursing call nurse station management terminal, nursing call doctor duty terminal, patient information display screen, ward entrance nursing call terminal, bed nursing call terminal, door light, emergency call button, corridor information display screen, and so on. The intelligent ward nursing call system, which serves as a functional implementation and control, must simultaneously have a series of functional modules such as doctor-patient intercom calls, patient information electronic dashboards, mobile receiving terminals, infusion monitoring, etc. The detailed functions are as follows:
1. The system is built in B/S mode: Web browsing does not need to install controls, but through Internet remote access, log in to the system management platform with department account permissions, which can achieve unified management of equipment in branches and other branches in different places or regions.
2. Dual mode intercom: When the server is connected normally, the bedside extension and the management machine can make two-way calls and intercoms; When the server goes down (you can unplug the network cable and wait for a few seconds), the hospital bed extension can still call the nurse station management machine, and the ward entrance machine can also call the nurse station management machine; Both can have intercom calls.
3. One call, one response: When the hospital bed extension calls the management machine, a group call is used, and all extensions in the group ring together to remind. After any extension in the group answers, the call bell ends and the intercom begins.
4. Call group management: Call groups can be managed by adding or removing extensions through the business backend, supporting the addition and removal of device groups, making business applications more flexible and calling more efficient.
5. Dynamic nursing positioning: The system dynamically joins and removes call groups based on the nursing function of the equipment. After joining, the corresponding equipment supports connecting calls for intercom and automatic withdrawal from nursing. When the nurse enters the ward, press the "Nursing" button on the entrance machine of the ward, and the machine will display "Nursing in progress", the door light will be green, and the corridor screen will display "XX room nursing in progress".
6. Unprocessed Event: Generate an unhandled event according to the rules, and an unhandled event will be generated on each call or alarm management machine and auxiliary machine.
7. Call management console: Open the settings for call management console in the management console settings.

Terminal device deployment plan
1. Network connection method
Wired network
Terminal devices that support wired networks include: nurse station medical terminals, nurse station intelligent signage, electronic door signs, electronic bedside cards, and corridor display screens. Most wired networks are old residential areas without wireless signal coverage, and the network requirements are as follows:
2 Deployment Implementation Conditions
Network requirements
Network bandwidth: Interlayer switches require gigabit level
Taking a building with 20 floors and an average of 50 terminals per floor as an example for calculation. The required speed for watching TV at each terminal is 400kBps. The calculation shows that the required bandwidth is: 20 * 50 * 400kBps=400MBps, so the peak occupied bandwidth is 400MBps * 8=3200Mb. Nowadays, the switches used for building to building networks in hospitals are all 10 Gigabit switches, which account for 30% of the switch bandwidth during peak conditions and less during normal use.
Network IP planning and allocation
A fixed IP address within the hospital intranet needs to be assigned to the server in order to access the hospital network;
Hospitals need to reserve a network segment to assign IP addresses to terminals;
The IP addresses assigned to the above two points require normal communication with the hospital HIS server.
External network requirements
Version updates and bedside payment functions require access to the internet, so it is necessary to grant the server internet access, with ports 3309 and 8080 temporarily opened. Negotiate further if there are business requirements.
