Then the medical staff extends their hands into the disinfection chamber 29 to disinfect their hands, and the disinfected waste water flows into the waste liquid box, and the liquid outlet valve pipe 25 is opened regularly to discharge the waste water. Open the storage box 2, take out the retractable lead wire 7 and the disposable EEG monitoring sensor of corresponding specifications, connect the BI connector 41 of the retractable lead wire 7 to the BI interface 38, take out the disinfecting alcohol in the storage box 2, wipe the patient's forehead skin with alcohol and wait for it to dry; Tear off the two blocking protective paper films of the disposable EEG monitoring sensor, quickly disconnect the first IC card male connector 45 and the sensor female connector 43 or quickly disconnect the second IC card male connector 50 and the sensor female connector 43, and automatically extend the telescopic lead wire 7 and manually reel it up, so as to facilitate the placement of the disposable EEG monitoring sensor to any suitable position, and sequentially place the three split sensor patches 47 marked with 1, 2 and 3 on the patient's head, or sequentially place the four connected sensor patches 48 marked with 1, 2, 4 and 3 on the patient's head; Press the outer edge of the patch to make it in good contact with the skin, and press the center of each patch for 5 seconds. In order to prevent the sensor from being twisted and falling off by external force, when connecting the telescopic lead wire 7, the medical tape inside the storage box 2 can be taken out to fix the disposable EEG monitoring sensor or the telescopic lead wire 7; After taking out various items from the storage box 20, the types of items are switched and counted through a number of counting buttons 26, and the types and quantities are displayed through the counting display screen 27. When the preset critical value is reached, a reminder is given to replenish the corresponding items; Click the collection button on the menu bar of the touch screen 39 to start collecting EEG signals. The disposable EEG monitoring sensor cooperates with the blood oxygen saturation collection module, the ECG collection module, the body temperature collection module, and the non-invasive blood pressure collection module to monitor the patient's EEG state through the disposable EEG monitoring sensor patch to collect body temperature, ECG and various EEG signals, and transmit them to the processing module to perform technical processing on the data signal. The BI value is output in the form of 0-100 and displayed through the mobile host 10; The clinical status corresponding to the BI value range is as follows Fig.10 As shown: The depth of anesthesia index uses numbers 0-100 to represent the clinical depth of anesthesia. The smaller the number, the higher the degree of sedation. It is divided according to the relevant important clinical manifestations and EEG status during anesthesia. BI close to 100 represents a clear clinical state; BI of 60-80 represents moderate sedation; BI of 40-60 represents the range of anesthesia sedation levels suitable for surgical operations; BI of 0 represents the electroencephalogram isoelectric state; It also automatically scores the depth of anesthesia consciousness for use in operating rooms, neurosurgery, intensive care units, and clinical research to assess the patient's EEG consciousness state; The optical drive 13 is used to place the optical disk for data backup; the transfer interface 19 is used to connect external devices such as computers to copy data; the input keyboard board 6 is used to switch the interface of the mobile host 10, input data and other functions; the printer 12 is used to print relevant data; The electronic control host 33 is wirelessly connected to the medical monitoring station to transmit the data to the medical monitoring station of the hospital for observation by relevant medical personnel.

A hollow rotation shaft 9 is rotatably arranged in the middle of the upper end of the mounting plate 31, which can drive the mobile host 10 to rotate to a use angle. When the mobile host 10 needs to be transferred, the mobile host 10 can be removed from the clamping base 8, and the winding wire 20 is used to extend the wire harness. The mobile host 10 can be placed in any use position to meet the use requirements. When the mobile host 10 is placed back on the clamping base 8, the winding wire 20 is used to automatically wind up the wire harness, which is convenient for moving and using the mobile host 10; After the monitoring is completed, the information is transmitted to the electronic control host 33 through the control button area 17, and the electronic control host 33 controls the flip cover electric push rod 24 to start, and the flip cover electric push rod 24 is folded, and the garbage cover 22 is opened around the hinge seat 23, and the used disposable EEG monitoring sensor and used medical tape and other waste are put into the garbage box 21, and then the garbage cover 22 is closed around the hinge seat 23 through the control button area 17, and the garbage bag in the opened storage box 2 is taken out regularly, and a new garbage bag is replaced and put into the garbage box 21; Finally, the mobile host 10 is turned off and folded up.

[0062] EEG (electroencephalogram) shows the spontaneous and rhythmic electrical activity of brain cell groups, which is generally described by characteristics such as amplitude, frequency and phase. During general anesthesia, the EEG frequency changes sequentially as the anesthesia deepens or becomes shallower, and is a function of the anesthetic concentration. Fourier transform technology is used to analyze the EEG frequency domain characteristics, convert the original EEG signal of the EEG time-amplitude relationship into a frequency-power relationship, and derive multiple quantitative parameters, such as αratio, βratio, βratio-αratio, BS% (burst suppression ratio), where αratio and βratio refer to two energy ratios. These two values ​​represent the essence of the energy conversion from high frequency to low frequency during anesthesia.

[0063] The burst suppression ratio (BS%) refers to the percentage of the time when the EEG amplitude is less than 3.5 μV in a 30-second period; αratio=ln(E30-42.5Hz / E6-12Hz); βratio =ln(E30-42.5Hz / E11-21Hz); βratio-αratio =ln(E6-12Hz / E11-21Hz); The total amount of instantaneous inhibition bursts within a 30-second EEG cycle is calculated instantly. These four parameter values ​​can be input into a fuzzy logic classification system to calculate the depth of anesthesia index. The brain activity signal is measured 2000 times per second, and several EEG sub-parameters are combined in an adaptive neuro-fuzzy inference system to obtain the BI depth of anesthesia index; the calculation process of the depth of anesthesia index is as follows Fig.11 shown.

[0064] In summary, by cooperating with the mounting plate 31 and the upper wire support tube 32, the mounting plate 31 can be rotated to drive the input keyboard plate 6, the hollow rotation shaft 9, the handle connecting piece 11 and the mobile host 10 above it to rotate synchronously, which is convenient for using the mobile host 10; through the storage box 2, it is convenient to take and put medical supplies, and the counter 3 is used to count the taking and putting, and remind to replenish the corresponding consumables; the hands of medical staff and patients are disinfected through the disinfection mechanism 4, and medical waste is collected and placed through the medical waste box 5; through the hollow rotation shaft 9 and the clamping base 8, it is convenient to flip the mobile host 10, which is convenient for medical staff to use, and at the same time, through the clamping base 8, the mobile host 10 and the winding wire 20 are coordinated, it is convenient to remove and transfer the mobile host 10 for use. Host 10; the disposable EEG monitoring sensor can be quickly connected through the telescopic lead wire 7, and the telescopic lead wire 7 can be stretched to meet the disposable EEG monitoring sensor for more convenient mobile use; the disposable EEG monitoring sensor can be stably attached to the skull with less muscle fibers to obtain the best quality signal, and through cooperation with the blood oxygen saturation acquisition module, the ECG acquisition module, the body temperature acquisition module, and the non-invasive blood pressure acquisition module, the patient's EEG state is monitored through the disposable EEG monitoring sensor patch to collect body temperature, ECG and various EEG signals, and transmit them to the processing module, the data signal is technically processed, real-time monitoring, and BI value is obtained in real time.
