Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation training models, and in particular to an intelligent training model for cardiopulmonary resuscitation and a training method thereof. Background Art

[0002] Cardiopulmonary resuscitation, referred to as CPR, is a life-saving technique for cardiac and respiratory arrest. It is designed to restore the patient's spontaneous breathing and circulation. Cardiac arrest refers to the sudden cessation of the heart's beating due to various reasons in unexpected circumstances and time, which leads to the sudden cessation of effective cardiac pump function and effective circulation, causing severe ischemia, hypoxia and metabolic disorders of tissue cells throughout the body. If not rescued in time, life can be lost immediately. Cardiac arrest is different from any cardiac arrest in the terminal stage of chronic diseases. If correct and effective resuscitation measures are taken in time, the lives of people in distress may be saved and recovered. Since the beginning of this century, major natural disasters in my country have caused a total of 130,636 deaths and disappearances, with direct economic losses of 663.684 billion yuan. The treatment of critically injured patients at the scene of emergencies is the core and difficulty of the entire rescue mission. Cardiopulmonary resuscitation training is generally practiced on cardiopulmonary resuscitation robots.

[0003] Existing CPR robots have the following shortcomings: 1. They only have simple pressing or compression-ventilation functions, and cannot truly simulate the steps of real CPR, collect dynamic information of the neck and shoulders, and cannot intelligently collect the frequency and depth of compressions. They cannot collect the exhaled volume during artificial respiration, and are still far behind real CPR; 2. They cannot collect the chest pressing movements of staff during CPR training and intelligently analyze whether the movements are standard, and cannot provide intelligent scoring after CPR training.

Then the staff crosses his hands and presses vertically downward with the weight of his body. When the pressing plate 16 is pressed downward, the guide column 20 slides downward along the guide sleeve 19 to ensure that the pressing plate 16 moves downward smoothly. At this time, the spring 18 is compressed and shortened. After the pressing force is cancelled, the spring 18 resets to make the pressing plate 16 rebound. When simulating real first aid, it can be pressed continuously for multiple times. The pressure sensor 15 installed at the pressing position on the top of the pressing plate 16 detects whether the staff's pressing position is correct, transmits and displays it on the display screen 8.

The scoring program written in advance in the computer host 4 reads the data of this first aid step in the computer host 4 for scoring and displays it on the display screen 8. ;
