Talking about the Application of IP Surveillance in Medical Industry

With the continuous improvement of hospital information construction, network has become the mainstream of hospital video surveillance development. The flexibility, openness, and scalability of IP surveillance are also promoting the extension of hospital video surveillance to a wider range of applications.

In addition to being able to implement traditional security applications, IP surveillance can also provide hospitals with extended applications such as surgical teaching, remote viewing, remote nursing, and telemedicine consultations, thereby comprehensively improving hospital management efficiency and service quality.

Security Monitoring

Security is still the most important application of IP surveillance in hospitals, covering areas such as fire prevention, theft prevention, and prevention of personal disputes and violent incidents. The purpose is to protect the lives and property of medical personnel, patients and their families.

According to the division of hospital internal management area, the key protection areas of hospital security monitoring can be mainly divided into medical area, medical technology area, logistics area, alarm area, access control area and administrative area: medical area including waiting hall, registration fee window, ward aisle, ICU, operating room, source room, transfusion room, emergency hall, etc.; medical technology area includes scientific research building, central laboratory, pharmacy, drugstore, CT, linear accelerator, laboratory, etc.; logistics area includes hospital gate, main building Entrances and exits, hospital walls, yards, parking lots, monitoring centers, information centers, etc.; alarm areas include registration and charging windows, finance departments, toll collections, isotopes, pharmacies, drug stores, canteen warehouses, etc.; entrance areas include the office of the dean, ICU Intensive Care Units, Operating Rooms, Radioactive Source Rooms, Surveillance Centers, Information Centers, Central Laboratories, Pharmacy, Pharmacy, Finance, Valuable Instruments and Equipment, and Registration Fees; Administrative Areas Including Stairways, Doctors and Patients Communication sites, security departments, etc.

Different areas of monitoring are different, and the purpose of prevention is also different. For example, the waiting hall monitoring is mainly to prevent personnel disputes and thefts. The registered fee collection office monitors major prevention services and money and money disputes. The pharmacy drug store monitoring mainly prevents fire and theft. The wall monitoring mainly prevents external personnel from illegal invasion. The information center monitoring mainly prevents theft and Room environment faults, etc.

With the IP video surveillance solution, a digital hospital security system can be rapidly built based on the existing local area network of the hospital to facilitate centralized management, and can be accessed anytime, anywhere, and with low deployment cost, to achieve panoramic real-time monitoring of all the above-mentioned prevention areas and prevention locations. management.

The monitoring center is usually located in the central control room and can be equipped with an IP surveillance management platform/NVR, storage and video wall. Monitoring points are located in the above-mentioned hospitals inside and outside the defense area and the prevention site, equipped with high-definition/standard-definition IP cameras and related peripheral equipment. The images, sounds, and alarm signals of each monitoring point are processed by the IP camera and then centrally uploaded to the monitoring center through the local area network of the hospital. The management platform manages, distributes, and stores them in a unified manner.

According to the different monitoring locations, the peripheral equipment of the monitoring points will also be different. Most of the monitoring points are relatively simple. Generally, only the live video needs to be collected for code upload, and no other peripheral devices need to be deployed. For some special monitoring points, due to the different purposes of prevention, it is often necessary to deploy additional supporting equipment. For example, pickup stations are often required to deploy pickups, and live sounds can also be monitored to better understand service disputes; pharmacy drugstores Need to deploy smoke, temperature, infrared and other fire and burglar alarms, generate alarm signals when a fire or personnel intrusion occurs, and then automatically trigger the monitoring center to generate a series of actions through the alarm linkage function provided by the system, including switching the monitoring point image Wall, sound and light alarm to remind the monitoring center staff, and start monitoring points at the same time recording; information center needs to deploy the engine room humidity, temperature, power and other power environment parameter detection equipment, when the parameters exceed the standard alarm signal, automatically trigger monitoring center linkage At the same time, these parameter information can also be superimposed on the monitoring image. In areas such as walls and ICUs, equipment such as infrared and access control devices need to be deployed. When an intrusion occurs, an alarm signal is generated and the monitoring center linkage is automatically triggered.

Due to the adoption of a fully networked architecture, the entire system is very flexible in terms of monitoring point access and client access. The monitoring point can be connected to the hospital LAN through a wired method, and can also access the hospital LAN through wireless. The client can be based on the hospital's internal office network, it can also be based on the Internet, or even monitor images based on mobile phone access.

Remote access

The hospital has some special wards, on the one hand because the patient's condition is seriously vulnerable to external infection, on the other hand because the patient's own disease is highly contagious and cannot be in direct contact with the outside world. Typically, such as the Intensive Care Unit (ICU), this is a special place focused on treating critically ill patients. The patients admitted here are all postoperative patients and critically ill patients with the lowest resistance, the most prone to complications and serious infections. However, this type of patient often requires the escort and comfort of family members at the same time.

In order to solve this problem, remote video access can be achieved through an online video surveillance system. This will not only protect patients from external infections or cross-contamination, but also enable “face to face” parental communication between patients and their families.

Deployment requires high-definition or standard-definition IP cameras and microphones, speakers, and televisions in special wards. At the same time, a remote visiting room is set up outside the quarantine area, equipped with high-definition or standard-definition IP cameras, PCs, and headsets. These facilities are accessed through the hospital LAN. Monitoring center management platform. Family members or friends can see the indoor patient's situation in real time in the outdoor visiting point and communicate with the patient. The patient can also see the video of the family member outside.

If the management platform is connected to the Internet, family members or friends can log in remotely through the PC even when they are at home or in the field. It is convenient and quick to visit the patient with the intercom.

Surgery teaching

Clinical teaching is an important task of the hospital and is responsible for training the backup medical staff. The previous teaching methods are usually on-site observation. However, on the one hand, due to on-site conditions or limitations of surgical equipment, the space for on-site observation is limited and the number of participants is limited. On the other hand, because operating rooms and other places are places where cleanliness is demanding, in order to reduce cross-infection, generally it is not allowed outside. Personnel and non-surgical medical personnel randomly enter and leave, and at the same time, the flow of many people will also bring unnecessary trouble to the patient's normal treatment. Therefore, on-site teaching and communication activities are greatly limited and the results are not ideal.

The construction of a visual remote teaching system through IP video surveillance can solve this problem. The operating room is equipped with a high-definition panoramic camera, a tactical camera, and a pickup, plus vital signs data and endoscopic images, together with a monitoring platform or NVR. External observers and learners can watch the game remotely through the TV or PC login system in the hospital observation room and the teaching hall. They can see real-time images, hear real-time sounds, and even communicate with the operating room personnel via voice. communicate with. The whole process of surgery can also be recorded by NVR for later online on-demand learning. Observing and learning staff can also observe and learn through the Internet remotely even if they are outside the country.

Telemedicine consultation

Due to the unbalanced development of the medical level in the country, the tertiary hospitals are basically distributed in large and medium-sized cities. High-grade, sophisticated, and sharp medical equipment are also distributed in large cities. Patients, especially those in remote areas, are lagging behind in local medical conditions. Critical and difficult patients are often sent to higher-level hospitals for expert consultation. Treatment expenses, family escort fees, and inpatient medical expenses all add to the financial burden on patients. At the same time, the bumps on the road have also caused harm to the already fragile body of the patient, and many patients who do not have the conditions to attend a major hospital have delayed the diagnosis and treatment, causing physical and psychological suffering to the patient and family members. Even in big cities, patients want to be able to go to tertiary hospitals to receive treatment from specialists, causing patients in primary hospitals to flow into municipal hospitals. This increases the burden on municipal hospitals, causing strained beds, and the lack of basic beds, resulting in the distribution of medical resources. Uneven and wasteful.

With the aid of the IP video surveillance system, an effective telemedicine network can be formed through the borderless interconnection of medical institutions at all levels to realize the transmission, storage, query, comparison, display and sharing of medical data and remote video and audio information. Patients in remote areas can easily share excellent medical resources and solve these problems.

In deployment, a remote medical or teleconsultation point is set up in the hospital, equipped with high-definition or standard-definition IP cameras, microphones, and speakers to access the monitoring center management platform. External cooperative hospitals and foreign experts remotely log on to the hospital management platform through a TV or PC to remotely diagnose and remotely treat patients at the consultation point, watch the patient’s injury, and communicate with the patient through voice intercom, which solves some problems. The problem of insufficient hospital experts saves the cost and time for patients seeking medicine everywhere.

With the development and popularization of high-definition video surveillance, high-definition medical image data can be transmitted over a network. Therefore, telemedicine consultations will be more widely deployed and applied in hospitals.

Telemedicine

Strengthen the humanization and intelligent management, keep abreast of each patient's specific situation, reduce the patient's psychological and physical burden, so that families are more assured that the patient will be handed to the doctor's hands, is the key to the hospital to improve service concepts and service levels .

The use of IP video surveillance to achieve visual remote nursing can effectively improve the low efficiency, confusion and disorder of traditional manual cries, improve the voice transmission and hospital queuing service environment in hospital wards, and improve the working conditions of medical staff to enable them to be in a convenient environment. In order to provide a good service for the patients, we can speed up the modern management process of hospital operations.

In deployment, HD or SD IP cameras, pickups, speakers, and call buttons are installed in the wards, and PC clients and intercom devices are installed at the nurses' stations. There are several kinds of applications: First, the patient actively initiates the call information of the linked nurse station client through the call button in the ward. The nurse staff on duty can instantly see the image of the calling ward, and communicate with the patient to provide a shortcut. The second is nurses on duty staff can call a certain ward initiatively, observe the patient's condition in real time, and communicate with the patient; Third, nurses on duty duty staff can call or group call multiple wards, broadcast speeches to these patients, Focus on notifications or remind related issues.

Through the combination of IP cameras and relevant medical facilities in the wards, it can also provide more intelligent and more humane services. For example, it is connected to an infusion alarm. When the infusion is completed, the patient is automatically alerted to the nurse station through the alarm linkage of the monitoring system. It is connected to instruments such as a blood pressure meter, an electrocardiograph, and a bedside monitor to achieve automatic alarming and superimposed display of data parameters and monitoring images. In the event of an abnormality, the nurses should be informed in a timely manner to notify the nurses.

Conclusion

Since the arrival of the network, hospital video surveillance is no longer confined to the traditional security, but more and more integrated with the hospital's own business, remote surgical teaching, remote visits, remote care, telemedicine consultations are very Typical application manifests. With the convergence of 3G, WIFI and surveillance, it becomes possible to transmit clear and smooth surveillance videos on the move. Hospital video surveillance will present a broader application space and the hospital security market will usher in new growth points.
