■ The anatomical position of the simulated human head and neck is accurate, the head can swing left and right, and the horizontal rotation is 180 degrees, which is convenient for removing foreign bodies in the oral cavity.
■ The eyeball is simulated by OLED, visible color retina, black pupil, transparent crystal, which can reflect light at any angle; pupil's light reflex exists, and the pupil changes automatically with the change of the condition. In the state of death, the pupil is dilated and the light is reflected. disappear.
■ The carotid artery pulse can be palpated. In the state of death, the carotid artery pulse disappears; the carotid artery pulse intensity has force feedback.
■ The head is equipped with sensors, and the open airway can automatically feedback.
■ The system is divided into student side and teacher side.
■ The teacher can invigilate exams, view and manage scores, set exam standards, edit and add scenes.
* Transcript management: record all transcripts of the assessment, and the transcripts can be retrieved, viewed or deleted according to the mode and student name.
■ The student side includes 3 modes, training mode, assessment mode, and actual combat mode.
■ The system has built-in different CPR scenarios, including: electric shock, drowning, cardiac arrest, trauma, poisoning, accidental hypothermia, anaphylactic shock, etc. Users can also add new scenarios, or edit and modify existing scenarios . Each scenario can have independent operating procedures and scoring criteria.
■ Invigilation function: In the student assessment mode, the teacher can use another mobile phone to connect the simulator to enter the invigilation mode, check the students' operation records, real-time operation data, and control the assessment reset.

Electronic monitoring of multiple indicators throughout the process:
* Pressing part: Monitor the number of pressings (press more, press less), pressing position (correct, wrong), pressing depth (too large, too small), pressing frequency (correct, wrong), pressing rebound, pressing interruption time display.
* Pressing operation waveform display: Display the pressing operation waveform in real time. Through the waveform, you can judge the pressing depth, pressing frequency, pressing rebound, pressing interruption time, pressing position, etc.
* Partial monitoring of blowing: blowing times (more blowing, less blowing), tidal volume (too large, too small), tidal time, and gas into the stomach. Blowing operation waveform display: real-time display of the blowing operation waveform, through which the tidal volume and tidal time can be judged.
