EEG signal monitoring quality stability system for anesthesia depth monitor

Abstract

The invention discloses a EEG signal monitoring quality stability system for an anesthesia depth monitor, and relates to the technical field of EEG signal monitoring, wherein the EEG signal monitoringquality stability system includes a brain electrode for collecting a brain signal, an amplification filter module for amplifying and filtering the brain signal collected by the brain electrode to obtain an required EEG signal, a signal processing module for converting the EEG signal outputted by the amplification filter module into an EEG digital signal, a displayer for displaying the EEG digitalsignal outputted by the signal processing module, and a power supply module for supplying power for the brain electrode, the amplification filter module, the signal processing module and the displayer. The EEG signal collected by the brain electrode can be amplified and filtered, the required EEG signal with stable quality is obtained, the EEG signal is converted into the analog signal, and the analog signal is displayed on the displayer in the way of anesthesia depth index (CSI). The EEG signal monitoring quality stability system is beneficial for monitoring the sedation and hypnosis degreeof patients intuitively and accurately during the use of the anesthesia depth monitor.

Description

technical field [0001] The invention relates to the technical field of EEG signal monitoring, in particular to an EEG signal monitoring quality stabilization system for an anesthesia depth monitor. Background technique [0002] Depth of anesthesia monitor, used for monitoring the depth of anesthesia in patients undergoing general anesthesia, can display the degree of sedation and hypnosis of the patient in real time, ranging from 100 to 0 (from fully awake to no EEG signal), attached to the head of the human body through brain electrodes The EEG signal is collected and displayed on the monitor as a number from 0-100 (depth of anesthesia index CSI), which is used to indirectly display the degree of sedation and hypnosis of the human body after anesthesia. However, during the acquisition process of EEG signals, the signal level is weak and mixed with interference signals, which greatly interferes with the monitoring results. Therefore, whether the quality of EEG signal monitor...

Problems solved by technology

However, during the acquisition process of EEG signals, the signal level is weak and mixed with interference signals, which greatly interferes with the monitoring results, so whether the quality of EEG signal monitoring is stable or not is very important
