Embodiment Construction

[0021] The following is based on Figure 1 to Figure 5 A preferred embodiment of the present invention is given and described in detail so that those skilled in the art can easily understand the structural features and functional features of the present invention, rather than to limit the scope of the present invention.

[0022] see Figure 1 ~ Figure 3

[0023] EEG waveforms show the spontaneous and rhythmic electrical activity of brain cell groups, and EEG is generally described by characteristics such as amplitude, frequency, and phase. During general anesthesia, the EEG frequency changes sequentially with the deepening or lightening of anesthesia, and has a functional relationship with the concentration of anesthetic drugs, which is used to reflect the depth of anesthesia. With the maturity of fast Fourier transform technology, more and more EEG frequency domain features can be used to reflect the depth of anesthesia, convert the original EEG signal of time-amplitude rel...

Abstract

The invention provides an electroencephalogram monitoring device of anesthesia depth including a brain wave collection amplification and data processor (1) and a display (2), which is characterized in that the electroencephalogram monitoring device also includes a computer (3), a software main body (4) mounted in the computer (3) and a brain function index analyzing module (46), wherein the computer (3) and the brain wave collection amplification and data processor (1) are bidirectionally connected by an USB bus, and the computer (3) sends processing results to the display (2) to display. The electroencephalogram monitoring device has advantages of: 1. more accurately using anesthetic to stabilize maintenance of anesthesia and synchronously reducing dosage of anesthetic; 2. ensuring that patients have no aesthesia during operation and no memory after operation; 3. providing indications of quick sobriety and extubation, increasing revival quality after operation and shortening residence time in resuscitation room of patients; 4. more completely resuming consciousness of patients after operation; 5. instructing dosage of sedative for ICU patients to maintaining the patients at a more stable sedation level.

Description

technical field [0001] The invention relates to a monitoring device for the degree of clinical anesthesia and sedation, in particular to a device for monitoring the depth of anesthesia and sedation by using electroencephalography. Background technique [0002] The depth of anesthesia has always been a concern of anesthesiologists. How to achieve high-quality anesthesia effects through effective monitoring is very important for clinical operations and has always been a technical problem for anesthesiologists to solve. [0003] Regarding the brain wave waveform recorded by the EEG, it is usually described by the characteristics of amplitude, frequency and phase. Therefore, the existing EEG used to reflect the depth of anesthesia is described by the time domain characteristics of the EEG, and the main analysis of the EEG The geometric nature of the waveform, therefore, has not been satisfactorily resolved. Contents of the invention [0004] In summary, how to improve the str...
