Technical Field
The invention relates to the technical field of medical instruments, in particular to thoracic cavity sealing, hemostasis and liquid pumping equipment for battlefield emergency treatment.
Background
When a person breathes, the lungs move with the movement of the thorax by means of the two pleura layers. The two pleura layers form a closed pleural cavity, and only a small amount of serous fluid and no air exist in the pleural cavity. In a battlefield, when a soldier missile or fragment penetrates to cause rupture of the pleural membrane, air enters the thoracic cavity to form pneumothorax, and the capacity of the lung to move along with the thorax is reduced. Meanwhile, blood flowing out of the chest wall blood vessels is accumulated in the chest cavity to press the lung and the heart, so that the difficulty in breathing is further caused, respiratory distress and shock can be rapidly caused, and the fatality rate of battlefield wounded persons is further increased. In the Vietnam war, 3-4% of the wounded members admitted to the army hospital die from pneumothorax according to statistics. Despite the high fatality rate of pneumothorax, its first aid technique in the field of war is not complicated, and the combat rescuer (commot life, CLS) or sanitary soldiers are trained to handle it. Retrospective analysis of battle depreciation data by the US army found that 15% of the combat death causes were preventable, with pneumothorax accounting for 5% of all preventable combat death causes 33.3%, second only to major hemorrhage.
In contrast, in the first-aid link of the war wound site, the importance degree of pneumothorax evaluation and treatment is not enough, the treatment concept, technology and equipment are relatively backward, and the research and development of the pneumothorax first-aid treatment equipment suitable for the battlefield environment and combining the physical characteristics of officer soldiers is necessary.
