Field tension pneumothorax first-aid assembly

Abstract

The invention relates to the technical field of pneumothorax first aid, in particular to a field tension pneumothorax first-aid assembly. The field tension pneumothorax first-aid assembly comprises apuncture needle, wherein a needle head is arranged at the top end of the puncture needle, the puncture needle is connected with a transparent bottle body filled with water through an air pipe, a bottle opening is formed in the upper end of the bottle body, a film with a cross-shaped opening is arranged in the bottle opening, a check valve is arranged at the connecting position of the air pipe andthe puncture needle, and a one-way valve is arranged at the connecting position of the air pipe and the bottle body. The field tension pneumothorax first-aid assembly is simple in structure, convenient to operate and capable of meeting the requirements of field first aid, external air is effectively prevented from being reversely injected into the thoracic cavity through the a plurality of valves,air in the thoracic cavity can be consolidated to be exhausted from the thoracic wall, lung tissue is expanded again to recover the function, and the requirement of pneumothorax first aid is met.

Description

technical field [0001] The invention relates to the technical field of pneumothorax first aid, in particular to an outdoor tension pneumothorax first aid kit. Background technique [0002] Tension pneumothorax is a critical emergency. In war, tension pneumothorax caused by explosions is the second leading cause of death. In the wild, common trauma such as falling from a height and gravity impact can easily lead to rib fractures and lung contusions, forming tension pneumothorax. Sexual pneumothorax. [0003] Tension pneumothorax is formed because the trachea or lung tissue is damaged and a one-way valve is formed. After each inhalation, the gas in the lung is discharged into the chest cavity along with the valve, and gradually accumulates and increases. The pressure in the chest cavity increases and squeezes the lung tissue on the same side. Inability to expand breathing normally. The principle of first aid is to puncture into the chest cavity at the chest wall, so that the...

AI Technical Summary

Problems solved by technology

However, the device is bulky, and because the water-sealed bottle is required to be absolutely lower than the puncture plane, thereby restricting the patient's activities, it is difficult to apply it in the field or in war

[0005] The current field first aid measures are also very simple, which is to insert a syringe needle into the patient's pleural membrane to expel air, but this simple device is bidirectional, which can easily cause the outside air to flow back into the chest cavity, which is counterproductive
