The battle in 1942 made the Name of The Russian fighting nation famous all over the world, and the indomitable and indomitable spirit of the Russian military and people left a heavy mark in history. Stalingrad is located in the downstream of the Volga river west bank, is the inland waterway transport trunk, also is the important economic region of the central Soviet area to the south traffic throat, the city also has the Soviet union's biggest tractor factory (long-term play the role of Arsenal), strategic position is very important, so the war attached great importance to both sides of the city, want to through the campaign to cut off the other party, one party supply reinforcements line, one party want to defend the city for the subsequent development of the war.

There were more than 2 million casualties on both sides of the battle, and in some cases there were only a few soldiers left in the medical camp. And in the campaign, not only medical personnel, but also for the soldiers themselves, emergency self-rescue and first-aid kits play a vital role. In the absence of the medical staff and soldiers injured, the first aid kit became a soldier's survival tools. Today, I will introduce a common thing in a first aid kit -decompression brooch. This is an operation technique used to relieve the pressure increase caused by a large amount of air accumulation in the chest. It is mainly used for traumatic or spontaneous tension pneumothorax. Generally, closed drainage is used; large needle can be used to puncture and open exhaust at high air pressure during emergency, and closed decompression is used after relief. In actual combat, bullets, flying stones, etc. The puncture site should be selected to avoid lung tissue injury. During decompression, the patient should be closely observed and the accident should be handled immediately.
