The ICU visitation system mainly consists of HIS system data processing service, smart ward integrated management platform, remote visitation system platform, ward management system, medical host, visitation extension, bed extension, ward entrance machine, etc.
Hospitals can choose and configure different equipment based on their own scale, level of informatization, investment budget, and other comprehensive factors.
This system is an ICU visitation intercom system based on IP network architecture.

Scheme Description
One ICU ward is equipped with a ward management center (nurse station), and a set of ICU media servers are deployed to facilitate high-quality services and work efficiency.
The system is based on network transmission and uses TCP/IP protocol to transmit video, audio, and various control signals, making it easy to connect and access to the Internet. 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 network cables for transmission within the ward.
According to the actual situation on site, each entrance and exit of the ward is equipped with a ward entrance machine for visitors to confirm their identity through visual intercom with the nurse station. Medical staff can enter and exit through various means, such as card swiping, fingerprint recognition, facial recognition, etc.

Advantages of the plan
1) Fully digital networking
The system adopts TCP/IP networking method and implements intercom function through local area network. All audio, video, and data signals are transmitted through digital encoding, and the video supports H.263, H. 264 and other protocols; Audio supports H.711, H.723， Waiting for protocols, supporting PCM ADPCM, AMR, AAC, G.711 formats.
2) Easy installation and easy maintenance
The system adopts international standard network interfaces, making construction, maintenance and upkeep convenient. Using standard Category 5 network cables for easy maintenance and expansion, and minimizing the construction cost of pipeline lines.
3) Multi channel communication, not busy
The system can achieve point-to-point signal transmission and support multi-channel call intercom through networking.
4) Strong anti-interference ability
Each audio, video, and control signal adopts digital networking, with no loss in transmission, no interference from lines, and no distance restrictions.
5) Easy system upgrade
The digital medical intercom system can be remotely upgraded online, making it convenient for system improvement.
6) System operation and maintenance
Provide a system operation and maintenance management platform that constantly reflects the operating status of the system and equipment, as well as the amount of call and intercom data in the system, making it easier for the hospital information department to monitor the system status and reduce operation and maintenance costs.
7) Customized design for the entire hospital
The intelligent ICU visitation system has a comprehensive, modular, and intensive research and development, production and processing system, supporting customized services at the hospital or ward level for customers.

System Function Introduction
1 Touch display
Nurse station host: adopts full touch screen operation, with each touch button corresponding to a visit extension number and a hospital bed extension number. It can call the visit extension or hospital bed extension with one click, monitor the hospital bed extension, insert a call, force hanging up and other different operations;
Visiting extension: It adopts full touch screen operation and is equipped with a one click call button;
Bed extension: It adopts full touch screen operation and combines shortcut key calling method,

2 Visual intercom
Intercom between visitation extension and hospital bed extension: Both visitation extension and hospital bed extension come with built-in cameras. The visiting extension first calls the ICU medical host, and the medical staff call the bed extension to be visited through the ICU medical host. After confirming the conditions for visiting, the extension is transferred to the corresponding ICU bed extension. At this time, the family and critically ill patients have two-way visual intercom.
Nurse station host and bed extension intercom: Patients can directly call each other through the ICU bed extension and nurse station host for visual intercom.
The nurse station host can call back the visit extension or ICU bed extension, and the visit extension or ICU bed extension will automatically answer for visual intercom.
Visitors to the ward can make a one click call to the nurse station host at the entrance of the ward for video intercom.

3 large screens display
The ICU visitation extension in the visitation area can be connected to a LCD large screen display through a high-definition output port, allowing for synchronized viewing of patient call video footage during family visitation and intercom.

4 Panoramic and close-up video calls
Each ICU bedside can be equipped with a network camera, which allows family members to switch from close-up videos to panoramic videos through the ICU visitation extension during the visit period. It can support back and forth switching and is operated by family members.

5 audio and video recordings
It can record and record the process of calls, as well as the time of calls and conversations. The audio and video files can be stored on the extension and host for direct playback, or exported to the computer for playback and storage; When the extension and host are idle, they can automatically transfer audio and video files to the designated server.

6 Monitoring/Monitoring/Forceful Call
During the visit between family members and patients, medical staff can monitor and monitor the communication process between family members and patients through the nurse station host, and even forcibly cut off the communication based on the patient's status.

7 interjections
During the visit between family members and patients, medical staff can intervene with one party through the nurse station host. At this time, the other party will play a friendly reminder sound, mainly to increase the friendly reminder function between medical staff and family members and patients.

8 One click call
Both the visitation extension and the hospital bed extension support one click call to the nurse station host.
The nurse station host can call the visitation extension and hospital bed extension with just one click.

9 Check the hospital bed
The nurse station host supports viewing the patient's condition on the hospital bed, achieving the goal of monitoring the condition.

10 Ward door unlocked
The nurse station host can control the opening and closing of the ward door lock, and can visually communicate with visitors to achieve access and visitation management at the entrance of the ward.

11 WeChat Mini Program
On the mobile WeChat mini program end, log in and access through the hospital assigned account password to make appointments and initiate remote visitation calls.
