Children CPR simulator (large electronic box)

■  Made of artificial polymer materials, environmentally friendly and pollution-free; The anatomical landmarks are obvious and can touch the nipples, ribs, sternum, and xiphoid process, making it easy to operate and locate.
■  The anatomical position of the simulated human head and neck is accurate, and the head can swing left and right with a horizontal rotation of 180 degrees, making it easy to remove oral foreign objects, and the mandibular joint can move.

■  The eyeball adopts OLED simulation, with visible colored retina, black pupils, transparent crystals, and the ability to reflect light at any angle; The pupil has a reflex to light, which automatically changes with the condition. In a dead state, the pupil dilates and the reflex to light disappears.
■  The carotid artery pulsation can be palpable, and in a state of death, the carotid artery pulsation disappears; The intensity of carotid artery pulsation has force feedback, and the greater the pressure on the finger, the stronger the pulse beating, which can be perceived as whether there is a checked pulse.
■  The head is equipped with sensors, and the open airway can automatically provide feedback; Internally installed sensors can sense tapping and calling, and tapping calls can automatically provide feedback.
■  Cardiopulmonary resuscitation (CPR): supine position with head tilted back for easy removal of respiratory foreign bodies
   * Feasible chest compressions.
   * There are three feasible methods to open the airway: lifting the chin, neck, and jaw with both hands. If the airway is not opened, ventilation cannot be performed. It is feasible to perform mouth to mouth artificial respiration or use a simple respirator to assist breathing. When using correct mouth-to-mouth artificial respiration and simple respirator assisted respiration correctly, both the blowing display on the electronic display can display green (correct), and there is no need to set "mouth-to-mouth artificial respiration" and "simple respirator assisted respiration" throu
