During the infection of the new coronavirus, many experts reminded that the elderly should be alert to "silent hypoxia". Li Yanming, director of the Department of Respiratory and Critical Care Medicine at Beijing Hospital, said that since elderly patients are slow to respond to hypoxia after being infected with the new coronavirus, "silent hypoxia" may occur. The family members may feel that the breathing state of the old man seems to be quite stable, but the blood oxygen saturation may already be at a low level. For the elderly, it is necessary to closely monitor the overall condition of their body, including heart rate, blood pressure, respiration, blood oxygen saturation, etc., and seek medical treatment in time if they deteriorate. The sooner you see a doctor, the greater the success rate of treatment!
A monitor is a guardian that monitors our life signals.
A monitor is a device or system that can measure a patient's dynamic physiological parameters and compare them with known set values, and send out an alarm if there is an abnormality. With the rapid development of the medical industry, domestic hospitals have accelerated the process of informatization construction. The construction of hospital informatization requires iterative updates of informatization and digitalization of medical equipment. Traditional monitors have begun to develop into information monitors. This monitor integrates patient vital signs monitoring, clinical information processing, data interaction, and equipment information. It will bring great help to the vast number of medical staff in their daily clinical medical activities.
Through the medical sensor module, important parameters such as ECG signal, heart rate, blood oxygen saturation, blood pressure, respiratory rate and body temperature can be detected in real time. The system converts biomedical signals into electrical signals through the signal detection and preprocessing module, then samples and quantifies them through the data acquisition and processing module, and analyzes and calculates each parameter; compares the analysis results with the set threshold, and performs supervision and alarm; The test results can be displayed, stored and printed locally, and transmitted to the hospital HIS system through the network for information management.
System Diagram of Medical Monitor
The monitor mainly has three parts: signal acquisition, data processing, and information display: signal acquisition mainly collects human biological signals through sensors and converts them into electrical signals; data processing is responsible for analyzing and comparing the collected data; information display is mainly through automatic The built-in display screen displays ECG waveforms and various parameters, and is equipped with a printing device that can be directly printed and transmitted to the HIS system through the network.
