Definition and basic structure of monitor

The monitor (what is a monitor) can detect some important vital characteristics of patients in real time, continuously and for a long time, and has important clinical value. And this instrument can also be used in portable, mobile, and vehicle, which greatly improves the frequency of use. With the continuous development of sensing technology and electronic science technology, patient monitoring technology has also developed rapidly. At present, the monitoring parameters have evolved from the original single parameters to multi-parameters, including ECG, blood pressure, body temperature, respiration, blood oxygen saturation, respiratory carbon dioxide, invasive blood pressure, cardiac output, etc. This article mainly introduces the use method of multi-parameter monitor and its measuring principle. In the following space, editors of monitor manufacturers will share the knowledge of multi-parameter monitor (the principle of multi-parameter monitor) with you.

 Multi-parameter monitors (classification of monitors) can provide first-hand clinical information and diverse life characteristics parameters for monitoring and rescue patients. According to the use of monitors in hospitals, we understand that various clinical departments are in When using the monitor, none of them can be dedicated to the special plane. In particular, new operators do not know much about the monitor, which leads to many problems in the use of the monitor, such as the inability to fully play the function of the instrument, reduce the utilization rate, and the high rate of false failures.

The basic structure of the monitor

Monitors are generally composed of physical modules containing various sensors and built-in computer systems. Various physiological signals are converted into electrical signals by the sensor, and then sent to the computer for pre-amplification processing for result display, storage and management. The multi-function parameter comprehensive monitor can monitor ECG, respiration, body temperature, blood pressure, blood oxygen and other parameters at the same time.

The plug-in combination monitor is a high-end monitor, which is composed of separate detachable physiological parameter modules and a monitor host. Monitor manufacturer users can purchase different plug-in modules according to their own requirements to form a monitor suitable for their special requirements. The display technology used by the monitor: digital tube display, CRT display, LCD display (liquid crystal display), electroluminescence display (EL).
