Description
Technical Field
The utility model relates to a chest first-aid device, in particular to a chest first-aid device for integrating and fixing and softening chest wall and plugging open pneumothorax.
Background
If chest wounds are not effectively treated in war, the life of wounded can be influenced, and the high-efficiency and reliable chest wounds can be used for on-site first aid, so that the life can be saved. Chest wounds in war are not effectively treated with mortality rates as high as 50%. The traumas in the battlefield environment are complex and various, and compound injury often exists, so that the multifunctional medical first-aid equipment convenient to carry can greatly save lives of wounded persons.
Chest trauma rescue is based on the aspiration and exhalation principles of the lungs: when the human body inhales, the chest expands, the inner volume of the chest increases, the negative pressure increases, and gas enters the lung through the negative pressure, and then the lung naturally expands; when we exhale, the thorax is reduced, the volume in the chest is reduced, then the pressure in the chest is increased, and the gas is expelled from the lungs along with the pressure.
When the chest wall or the lung is damaged by external force, the chest cavity is communicated with the external atmospheric pressure, the negative pressure environment in the chest cavity is destroyed, the human body cannot breathe normally, the lung cannot be re-expanded and retracted, and the ventilation and ventilation functions of the lung are lost, so that pneumothorax is caused. First, the treatment principle of open pneumothorax is: blocking the open pneumothorax to prevent the thoracic cavity from communicating with the external atmospheric pressure; if tension pneumothorax is generated, namely when external air can only enter the chest cavity but can not be discharged, a high pressure state in the chest cavity is caused, and the treatment principle is to immediately discharge the high pressure air in the chest cavity. Both tension pneumothorax and open pneumothorax can severely affect the respiratory circulatory function of the injured person.
When the trauma causes the chest wall to be damaged and the ribs are fractured, the chest wall loses the integral osseous stress structural support, and the softened chest wall is formed. Along with respiratory movement, abnormal breathing occurs at the chest wall injury part, namely the chest wall is injured to collapse inwards during inspiration, the chest wall is injured to bulge outwards during breathing, so that the pressure in the chest is unbalanced, the lung cannot be normally re-expanded and retracted, and the heart function is also affected seriously. Therefore, in dealing with patients with multiple rib fractures, the primary treatment principle is to fix the softened chest wall.
In a battlefield environment, chest injury is often complicated, multiple injuries and compound injuries are taken as main factors, and single-function first-aid equipment cannot meet actual requirements of a battlefield. Therefore, the design of the battlefield chest trauma first-aid equipment integrating multiple functions is not suitable for slow operation.

The utility model comprises a chest guard board and a pneumothorax plugging device, when in use, the chest guard board is tied on the chest, thereby effectively realizing the fixation and softening of the chest wall and the plugging of the open pneumothorax, and leading the chest wound to be protected in a short time.
The chest guard plate is combined with the chest occluder, so that the chest is broken through by trauma or bullets, a plurality of ribs on the chest wall are fractured, the chest wall is softened, the chest is exposed to the outside atmosphere, and the chest guard plate can play a role in fixing and softening the chest wall and occluding an open pneumothorax.
When encountering tension pneumothorax, the pressure in the chest is far higher than the external pressure, and the air needs to be discharged in time. When the pressure in the chest cavity is less than or equal to the external atmospheric pressure, the chest cavity plugging device plays a role in plugging.
The inspiration and expiration principle of the lung is: when the human body inhales, the chest expands, the inner volume of the chest increases, the negative pressure increases, and gas enters the lung through the negative pressure, and then the lung naturally expands; when we exhale, the thorax is reduced, the volume in the chest is reduced, then the pressure in the chest is increased, and the gas is expelled from the lungs along with the pressure.
When the chest wall or the lung is damaged by external force, the chest cavity is communicated with the external atmospheric pressure, the negative pressure environment in the chest cavity is destroyed, the human body cannot breathe normally, the lung cannot be re-expanded and retracted, and the ventilation and ventilation functions of the lung are lost, so that pneumothorax is caused. First, the treatment principle of open pneumothorax is: blocking the open pneumothorax to prevent the thoracic cavity from communicating with the external atmospheric pressure; if tension pneumothorax is generated, namely when external air can only enter the chest cavity but can not be discharged, a high pressure state in the chest cavity is caused, and the treatment principle is to immediately discharge the high pressure air in the chest cavity. Both tension pneumothorax and open pneumothorax can severely affect the respiratory circulatory function of the injured person.
When the trauma causes the chest wall to be damaged and the ribs are fractured, the chest wall loses the integral osseous stress structural support, and the softened chest wall is formed. Along with respiratory movement, abnormal breathing occurs at the chest wall injury part, namely the chest wall is injured to collapse inwards during inspiration, the chest wall is injured to bulge outwards during breathing, so that the pressure in the chest is unbalanced, the lung cannot be normally re-expanded and retracted, and the heart function is also affected seriously. Therefore, in dealing with patients with multiple rib fractures, the primary treatment principle is to fix the softened chest wall.
