<p>A chest compression instructing device for cardiopulmonary resuscitation first aid is comprised of a control box (4), a microgravity sensor (1) connected by a wire (3) and a training simulation body (18). It comprises a control center (5), and a power management battery (10) is connected with the control center (5) for supplying it with electric power, so as to operate a compression depth display (9) and a voice broadcasting loudspeaker (6). The microgravity sensor (1) is connected with the control center (5). When a rescuer is performing chest compression aid for a victim, the microgravity sensor (1) is stuck on the chest of the victim, and is used to acquire signals of gravity and speed. The signals sent by the microgravity sensor (1) are input into the control center (5), operated and processed by the control center (5) for gravity, speed and displacement, and then output. The processed control signals are input into a display processor, and displayed on a luminescent tube (9) by the display processor. At the same time the processed control signals are input into a voice processor, amplified in power by the voice processor and broadcasted in form of voice prompts by the loudspeaker (6).</p> |
