  • Publication number: 20160335921
    Abstract: Disclosed is a cardiopulmonary resuscitation training apparatus. The cardiopulmonary resuscitation training apparatus comprises: a mannequin; a compression plate which is provided towards the chest area of the mannequin and generates a return force; and a display unit which displays the state of the mannequin and shows blood circulation movement in light-emitting lines, in accordance with the pressing of the compression plate. The display unit can be constituted in such a way that the blood circulation movement in the mannequin is displayed by means of LEDs, and the LED movement rate is varied or the LEDs emit light in different colours in accordance with the depth of pressing or the pressing rate of the compression plate. This gives the advantage that the user can implement cardiopulmonary resuscitation close to reality while being made aware of the compression depth and the compression rate.
