There is an urgent need for remote visits in many large hospitals. This demand comes from two aspects: one is that some patients suffer from highly contagious diseases; the other is that severely ill patients are susceptible to infection, so they cannot contact the outside world. This kind of special patients most need comfort and accompany, and their family members, relatives, friends, etc. are also worried and anxious because they cannot visit.
With the further improvement and improvement of the safety protection system and technology, the medical industry is fully equipped and capable of applying the latest high-tech achievements, leading the whole industry to a new level, providing the most advanced and timely medical services, and establishing itself Industry image, and can efficiently serve users. In order to promote the specific requirements of the hospital to achieve modernization and efficient management, it is proposed to combine the current industry development level, use advanced technology, adopt safe and reliable network monitoring solutions, and “integrate and network” the monitoring system to meet the needs of the development of hospital security work. of.
Remote visitation needs
We are no stranger to remote visits. On May 17, 2009, Premier Wen Jiabao of the State Council made a special trip to Beijing Ditan Hospital to visit Beijing’s first patient with H1N1 influenza. At Ditan Hospital, Premier Wen realized communication and condolences with this patient through the remote visit system.
At present, there is an urgent need for remote visits in many large hospitals.
1. For patients with highly contagious diseases
Our country is densely populated and is a country prone to large-scale infectious diseases, such as SARS in 2003 and H1N1 flu in 2009. Patients with these diseases need to be isolated, observed and treated, and cannot be in contact with outsiders during this period.
2. For severely ill patients
Severely ill patients have poor resistance and are susceptible to infections that make their condition worse, so they cannot contact the outside world.
3. For newborns
Many newborns need hospitalization, observation and nursing for various reasons. For hospitalized newborns, due to their particularity, the hospital does not advocate parental care. There is only one visit per week by the parents. During the visit, the nurse holds the child to the window for the parents to take a look. The bed doctor is separated by The window answers questions from parents.
4. For patients who are far away from their loved ones
Due to various reasons, many patients and their relatives and friends are in different places, and their relatives and friends cannot rush to the patient’s hospital for visits and accompany.
The above-mentioned patients urgently need the care and care of their relatives and friends during their illness; relatives and friends also urgently need to understand and grasp the patient’s condition, which is the need for remote visits in hospitals.
Integrated application of remote visitation and digital network security system
With the development of network technology and video coding technology, hospital security video surveillance systems have gradually changed from traditional analog video systems to network digital video systems. Digital and network-based security platforms can integrate other sub-weak current systems, such as traditional ward visits, through the integration of communication protocols.
The traditional ward visiting system needs to be built separately, and cannot realize unified management, storage, and scheduling. The above-mentioned problems can be perfectly solved through the embedded digital network video system popular in the industry. The use of embedded digital network video system as the hospital security system can integrate multiple hospital weak electronic systems, which greatly saves the hospital’s investment costs.
Ward design
The ward mainly realizes the audio and video playback of the family members and the transmission of the patient’s audio and video signals.
The digital network camera is installed on the front of the bed, avoid direct light when installing. The selected camera is equipped with a microphone and speaker interface, and the microphone and speaker in the ward are connected to the digital camera to realize audio input/output.
The visiting terminal is installed on a foldable mechanical telescopic hand, and the height and direction are adjusted according to the lying posture of the patient.
Considering that some critically ill patients are inconvenient to carry earphones, directional microphones and speakers can be installed next to the touch terminal to achieve voice intercom as well.
Family Visiting Room Design
The visiting room is equipped with a remote visit management terminal, equipped with a microphone and LCD screen; a digital camera is set directly in front of the visit management terminal to collect and transmit the audio and video signals of the visitors to the ward. By manually selecting the hospital bed number that needs to be connected from the attending doctor (all visits must be carried out under the consent of the patient’s attending doctor), the management terminal can be directly connected to the hospital bed terminal. You can also configure high-quality speakers and external microphones on the management terminal.
In order to avoid unnecessary troubles caused by medical disputes, the attending doctor can start the audio and video recording function in the family visiting room to store the audio and video data in real time for the conversation between the doctor and the family, and the conversation between the family members and the patients.

Function Design of Visiting System
1. Real-time audio and video intercom
Through the visiting management terminal of the visiting room, select a certain hospital bed number to establish a dedicated audio and video channel with the ward, and both parties can conduct real-time video chat.
2. Active connection in the visiting room
The visitation room is equipped with a remote visit management terminal, and the ward number and bed number can be selected through the mouse, which can quickly and accurately connect the audio and video of the other party.
3. Sub-control of nurse workstations
The nurse workstation is the administrator of the remote visitation system. The nurse has the authority to interrupt the audio and video calls between the two parties at any time according to the patient’s physical condition.
4. Audio and video data storage
The audio and video intercom data can be stored in the existing security video surveillance system of the hospital for inspection when needed in the future. There is no need to build a storage system separately.
Digital network security system requirements
1. Using an embedded distributed network architecture, the entire system is deployed and managed centrally, and fully integrates various subsystems and monitoring resources to achieve full access to hospital systems such as wards, outpatient buildings, inpatient buildings, medical schools, parking lots, and ambulances. Aspect monitoring and centralized management. Link the audio and video monitoring part with the access control and alarm system to improve the security level and rapid response capability of the hospital.
2. The system architecture is divided into a two-level architecture of the general monitoring center and the hospital. The monitoring between the two levels is connected through the local area network; it can realize emergency fire broadcasting, ward long-distance contact-free monitoring, long-distance contact-free visits, hospital environmental safety monitoring, and hospitals Office evaluation and monitoring, security patrol system, expert remote guidance and discussion, teaching observation, expert online consultation and other functions.
3. The hospital’s embedded digital network video system should have the following functions at the same time.
· Adopt two methods of local real-time monitoring and remote monitoring: realizing that both the level 2 monitoring center and the local security kiosk can monitor the smart hospital;
· Voice intercom and broadcast functions: the main monitoring center and the regional monitoring center realize intercom, broadcast and video image linkage with each floor of each hospital;
· Key parts prevention function: the key parts of smart hospitals to implement prevention, such as registration office, toll office, waiting area, medical waste treatment area, key department entrance, ICU intensive care unit, operating room entrance, canteen, elevator, parking lot, entrance and exit , Outpatient clinics, inpatient departments, infusion areas, etc., set up monitoring points to observe and record the activities of personnel in major places in an all-round way. Linked alarms, automatic pop-up videos and automatic recordings are set up;
· Access control and alarm control functions: realize access control and video image linkage; by installing the alarm host, it can also achieve 110 alarm linkage, and the alarm situation can be dialed to any phone number set on the alarm host to facilitate timely response to accidents The situation is dealt with.
· Ambulance on-board monitoring: 3G mobile monitoring equipment is installed in the rescue room and roof of the ambulance, and it can maintain audio and video communication and interaction with the hospital emergency department to fully ensure that the monitoring center monitors each ambulance in real time and rescues in time patient.
· Surgery teaching: to improve the quality of surgery and reduce the infection rate of surgery. The operating room of the hospital has formulated the control index for the number of observations in the operating room to strictly control the number of people entering the operating room. This creates opportunities for interns and medical students to learn to observe surgery Greatly reduced, is not conducive to improving the quality of study of interns and medical students.
The use of monitoring and teaching systems can enable interns and medical students to observe the operation process in the operating room and conduct real-time teaching. It not only reduces cross-infection in the operating room, but also guarantees the sterility requirements in the operating room, and at the same time expands the scope of surgical teaching. Completely get rid of the limitation of time, space and number of people in traditional teaching mode.
Concluding remarks
The application of remote visits in hospitals allows users to get rid of time and geographical constraints, and easily communicate in real time “face-to-face” anytime and anywhere, making the hospital’s services more humane and warmer, which is helpful for improving the contradiction between doctors and patients. Improving the image of the hospital and increasing the patient’s satisfaction with the hospital also have a certain effect; at the same time, as part of the hospital’s informatization construction, remote visits have also greatly improved the hospital’s own management level and efficiency, bringing more The effect of winning and benefiting from multiple parties.
