Cardio-pulmonary resuscitation pressing deep training model
Technical Field
The invention belongs to the technical field of medical training instruments, and particularly relates to a cardio-pulmonary resuscitation compression depth training model.
Background
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 mainly takes a human body model as a main part, and generally integrates all the operation 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 important indexes, wherein for the compression depth, if the compression depth is too deep due to too large compression degree, the internal skeleton 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 cardiopulmonary resuscitation presses the training device, when not pressing in place, only certain prompt effect is provided for the pressing depth or frequency, and muscle memory can not be well formed for the person to be trained, so that the training efficiency is low.
