Once sudden cardiac arrest occurs, if resuscitation cannot be rescued immediately and timely, irreversible damage to the brain and other vital organs and tissues of a patient can be caused after 4-6min, so that the cardiopulmonary resuscitation after the sudden cardiac arrest must be performed immediately on site. The training device for cardiopulmonary resuscitation compression is mainly based on a human body model, and generally integrates all the operational procedures of cardiopulmonary resuscitation of medical emergency into a simulated human body. In the compression training, the compression depth and the compression frequency are two relatively important indexes, wherein for the compression depth, if the compression depth is too deep due to too large compression force, the internal bones and organs of a patient are easily damaged, and if the compression depth is too shallow, blood cannot reach the brain in time, so that even if the patient wakes up, symptoms such as brain death and the like can be caused. When the existing cardio-pulmonary resuscitation pressing training device is used and is not pressed in place, the existing cardio-pulmonary resuscitation pressing training device only has a certain prompting function on the pressing depth or frequency, and cannot well form muscle memory for a person to be trained, so that the training efficiency is low.
