Briefly describe the new design ideas of monitor network informationization

1. Application of monitors

Monitoring the physiological parameters of patients is a key task in clinical diagnosis and treatment. It allows doctors to understand the instantaneous physiological changes of patients, so as to timely discover and deal with the problems of patients and ensure their life and health. In recent years, with the continuous improvement of China's medical level and the gradual improvement of the medical system and social security system, the performance level of clinical monitoring technology and monitoring products in hospitals of all levels has been significantly improved, mainly in the indicators of comprehensiveness, modularization, specialization, intelligence and information networking of monitoring products. Monitors are medical instruments used to monitor the patient's vital signs and timely respond to the patient's instantaneous physiological changes. They can help doctors accurately discover and deal with problems and ensure the safety of patients' lives. Most of the monitors in domestic hospitals are monitoring systems composed of bedside monitors and central stations. The main function of bedside monitors is to measure and display the patient's physiological parameters and waveform trends, and generate alarms and records at the same time. The main function of the central station is the centralized display of multiple beds, real-time and non-real-time information analysis, and large-capacity data storage. Commonly used are multi-parameter monitors, dynamic monitors, fetal monitors, sleep monitors, etc. The main application methods include bedside monitoring, central monitoring, dynamic monitoring, etc. In terms of structure, there are built-in, plug-in, desktop, vertical, and wall-mounted types; in terms of connection, there are wired systems and wireless systems; in terms of function, they can be divided into monitoring, analysis and processing, management software, etc. These products can basically meet the needs of various situations in hospitals.

At present, the application scope of hospital monitors in China has expanded from the initial anesthesia department, cardiac care unit (CCU), intensive care unit (ICU), emergency intensive care unit (EICU) and other departments to neurology, neurosurgery, orthopedics, respiratory department, obstetrics and gynecology, neonatology, sleep department and other wider ranges, towards multi-disease, multi-department, and multi-disciplinary applications; at the same time, it has also expanded from large hospitals to small and medium-sized hospitals and community medical institutions; from special use to conventional means.

2. Development trend of monitors

Since the birth of the world's first monitor, after more than 40 years, with the advancement of science and technology, the monitoring industry has developed rapidly. From the initial single parameter to multiple parameters, CRT picture tube to TFT LCD screen, from all-in-one machine to plug-in type, multiple button operation to knob, touch screen operation, new products and new technologies are constantly emerging. At present, the monitoring parameters that general monitors can provide are: electrocardiogram (ECG), non-invasive blood pressure (NIBP), oxygen saturation (SPO2), body temperature (TEMP), respiration (RESP), invasive blood pressure (IBP), end-tidal airway carbon dioxide concentration (CO2); the products of a few well-known monitor manufacturers can provide more "advanced" parameters such as cardiac output (CO), anesthetic gas (MG), mixed venous oxygenation (SvO2), continuous non-invasive cardiac output, continuous non-invasive cardiac output (ICG), depth of anesthesia (BIS), respiratory mechanics (RM).

In recent years, arrhythmia analysis and ST segment analysis have become standard features of many monitors. Some well-known brands of products also have ST-map, synchronous twelve-lead analysis, horizontal trend chart, head trauma/multiple trauma, hypovolemic shock, septic shock determination, malignant hyperthermia, respiratory management-alveolar compression, respiratory distress syndrome monitoring and other cutting-edge performance. Bedside monitoring has long exceeded the scope of parameter monitoring and has played a more auxiliary role in clinical decision-making, becoming a powerful assistant for doctors. One of the future development trends in the medical field is the construction of hospital informatization. As an important part of hospital informatization construction, monitoring products must also keep up with the pace of informatization construction and carry out corresponding supporting development.

III. Monitor network informatization

(I) Definition of monitor network informatization

In a narrow sense, the informatization hospital includes clinical information systems, medical imaging systems, electronic medical records, doctor workstations, nurse workstations and telemedicine systems. The clinical information system should pay attention to every clinical detail information, including clinical medical subjective information and objective information. The integration and integration of clinical medical objective information requires the informatization and digitization of medical equipment, which is the development trend of medical equipment. At present, traditional monitors are gradually developing towards monitor network information. This monitor, which integrates patient vital signs monitoring, clinical information processing, data exchange, and equipment information integration, will bring great help to the majority of medical staff. For example, Philips' original patented "Portal Technology" technology, the monitor is equipped with the "Portal" to directly observe other clinical information and management information on the hospital information network. It is not just a simple information observation, but also a two-way information interaction. Thanks to the control of the information flow engine, the monitor performance is guaranteed not to be affected by the network performance, and it maintains a seamless connection with the hospital network. That is, the bedside monitor screen can be used to observe other patient clinical information and management information on the hospital information network, while ensuring that the patient's monitoring function and clinical data security are not affected. Through the protection of the application server, the bedside machine can safely exchange information with other clinical information systems (CIS) and hospital information systems (HIS). All applications are executed on the application server, and the application results are displayed on the bedside machine screen and controlled by the bedside machine keyboard. The ability to integrate information far exceeds that of ordinary clinical networks.

(II) Advantages of monitor network informatization

From a technical point of view, there are the following advantages: 1. Single network, simplicity, industrial standard network devices, easy support; 2. Unlimited application range, in line with the future development needs of hospitals; 3. Support Citrix technology, which is currently the most widely used in global medical networks; 4. Information flow control engine (TCE); 5. Reduce the pressure of network support and maintenance. From the perspective of hospital management, the benefits are also obvious: 1. Change the hospital workflow and improve overall efficiency; 2. Improve working conditions and increase the enthusiasm of medical staff; 3. Patient-centered system, easy to get the understanding and support of patients; 4. Go beyond traditional monitoring concepts and provide patients with the best medical care; 5. Reduce overall costs and best investment protection. From the perspective of maintenance, it is also very simple: 1. Standard maintenance tools and means; 2. Remote maintenance and diagnosis services, shorten maintenance cycles and improve efficiency; 3. Instrument maintenance and maintenance through the hospital network, with a variety of service types to choose from; 4. Online user manual to reduce the workload.

(III) Clinical value of network informationization of monitors

First, while monitoring patients normally, doctors can view real-time measurement data, trend analysis charts, digital radiographs, ultrasound images, laboratory test reports and other examination results on the screen on site, and fully and accurately understand the condition. Nurses can view the patient's discharge and admission records, electronic medical records, electronic medical records, medication records, nursing records, cost status, etc. at the bedside. In addition, the monitor can also be used as an information exchange terminal. Doctors can also observe the information of other departments, departments and patients through the screen, and communicate, diagnose, analyze cases, etc. online. All of the above work does not rely on the central station, and can be completed by the monitor at the bedside, greatly increasing the flexibility and convenience of use. The network informationization technology of the monitor has unprecedentedly improved the information capacity of the bedside machine. Through the hospital's LIS and HIS network systems, unprecedented complete information is obtained to support rapid clinical decision-making. The monitor screen displays monitoring information and other clinical information at the same time, and the operation is very intuitive and convenient, and can be fully customized. A new concept of patient monitoring, the dream bedside monitor has become a reality. The all-round two-way information exchange can obtain complete patient information at any time and place, no longer relying on the central station, and clinical decisions can be made at the bedside. This monitor that integrates patient vital signs monitoring, clinical information processing, data exchange, and equipment information integration will bring great help to medical staff. It is a milestone in the development of digital hospitals (e-Hospital).
