Description

Technical Field

[0001] The invention relates to the field of medical kit equipment, in particular to a portable thoracentesis kit suitable for battlefield environments. Background Art

[0002] Thoracentesis, also known as pleural puncture, is a medical procedure in which a puncture needle is inserted from the intercostal space of the chest wall into the pleural cavity (between the lungs and the chest wall) to extract the fluid or gas in the pleural cavity. When there is too much fluid or air in the pleural cavity, it will compress the lungs, heart and large blood vessels, leading to symptoms such as difficulty breathing and chest tightness. Thoracentesis can effectively reduce the pressure in the pleural cavity, relieve compression symptoms, promote lung re-expansion and recovery of lung function by removing fluid or air in the pleural cavity. In addition, by extracting the fluid or air in the pleural cavity and performing various examinations, the nature of the fluid or air can be clarified, assisting doctors in making a more accurate diagnosis of the patient's condition.

[0003] On the battlefield, for wounded soldiers with chest injuries, in order to avoid excessive accumulation of fluid or gas in the chest cavity from compressing the lungs, heart and large blood vessels, resulting in difficulty breathing, chest tightness and endangering the lives of the wounded, emergency thoracentesis is required to exhaust and drain the air. In order to cope with this situation, the first aid kits of medical personnel on the battlefield are usually equipped with puncture instruments. The puncture kits currently used for thoracentesis generally use a steel needle to penetrate the chest cavity to exhaust and drain the air.
