The pneumothorax puncture needle provided by the invention has the advantages that shortcomings in the prior art can be overcome, and the pneumothorax puncture needle is reasonable and original in structural design.

Description

technical field [0001] The invention relates to a pneumothorax puncture needle and belongs to the field of medical instruments. Background technique [0002] Pneumothorax puncture is one of the most commonly used diagnosis and treatment techniques in thoracic surgery. The current traditional method is to use an indwelling puncture needle to puncture, pull out the needle core, leave the cannula at the drainage site, and then connect the drainage bottle and the drainage tube through the drainage tube. Drainage with a cannula, although this method is effective, also has the defects of a large number of devices, cumbersome operation steps, and inconvenient portability, especially when the patient is facing first aid or field treatment, the above defects are more prominent. A pneumothorax puncture needle for first aid (Patent No. CN201620769395.6) is disclosed in the prior art to solve the above problems. This kind of pneumothorax puncture needle in the prior art is mainly used ...

AI Technical Summary

Problems solved by technology

This kind of pneumothorax puncture needle in the prior art is mainly used in first aid and field treatment. After the puncture needle punctures, it is necessary to cover the puncture wound. In many environments, it is easy to cause infection

However, in outdoor first aid, there is often no suitable covering at hand, and it is impossible to cover
