What is quick-acting hemostatic powder?

According to Professor Pei Xuetao, Director of the Field Blood Transfusion Research Institute of the Academy of Military Medical Sciences, the characteristic of quick-acting hemostatic powder is that it selectively absorbs water molecules in the blood when directly acting on the wound, but does not absorb other components in the blood, resulting in the concentration of platelets and coagulation factors; at the same time, the heat generated after absorbing water enhances the aggregation speed and aggregation ability of platelets, thereby achieving rapid hemostasis.
In a live video demonstration at the "High-Tech Fair", a little white rabbit was anesthetized, the artery in its thigh was cut, and blood flowed like a stream. The quick-acting hemostatic powder was immediately applied, and the blood stopped flowing in 30 seconds. After being bandaged with a bandage, the rabbit woke up and was able to walk only 5 minutes later. In addition, clinical studies have also shown that this drug has been used to treat 46 patients with acute traumatic bleeding, with an average hemostasis time of about 30 seconds, the shortest time being 16 seconds, and the longest time being 56 seconds.
It is understood that in war, timely hemostasis and treatment play a very critical role in reducing the death rate and improving the level of treatment for war injuries. Excessive blood loss is also one of the main factors leading to death of civilians due to trauma in peacetime. In order to solve the problem of bleeding caused by various types of moderate and severe trauma, experts from the Field Blood Transfusion Institute of the Academy of Military Medical Sciences of the Chinese People's Liberation Army devoted six years of hard work and achieved initial success in the development of a new generation of internationally leading fast-acting hemostatic drugs in 2003.
