How was artificial blood invented?

When a patient loses a lot of blood and his condition is critical, he can save his life by transfusion of other people's blood. However, in the actual situation, the blood volume of hospital blood bank is always limited, which often cannot meet people's needs. Therefore, chemists and medical scientists have been studying artificial blood.

Interestingly, artificial blood is related to a mouse. As the saying goes, "A mouse spoiled a pot of soup." However, by chance, a mouse fell into the soup, which inspired scientists. /kloc-one day in 0/966, Dr. Clark, an American medical scientist, was absorbed in his research in the laboratory, and there was a special liquid-fluorocarbon on the table beside him. A commonly used experimental animal, the mouse, ran out of nowhere. The mouse jumped around and fell into a container full of fluorocarbon.

Clark stumbled upon the mouse that fell into the container. The little guy is soaked to the skin and still struggling tenaciously. Dr Clark was merciful and fished it out. After the mouse was rescued, it shook its hair calmly in front of Clark and ran away.

Clark began to wonder why rats were still so energetic in fluorocarbon solution instead of drowning. Is it the "magic" effect of fluorocarbon?

So, he specially got a white mouse, put it in a container full of fluorocarbon, and observed what was happening in front of him. The mouse struggled desperately in the solution, but after several hours, the mouse was still full of energy and struggled to climb out. If it falls into the water, the mouse will die for such a long time.

As a result, Dr. Clark became interested in fluorocarbons and began to seriously study this special substance. The results show that this solution has a strong oxygen storage capacity, even more than twice that of blood. Later, another scientist injected fluorocarbon solution into mice instead of blood. As a result, the mice can persist for a while before they die.

Clark's research results attracted the attention of the manager of Japan Green Cross Company. He immediately led the researchers to the United States for investigation. After returning home, he organized 150 experts to conduct research. The results show that fluorocarbon is not the most ideal blood substitute. Later, the research of artificial blood made new progress. 1979 In April, Green Cross announced that it had successfully researched artificial blood in the world. Artificial blood can be obtained by mixing fluorocarbon with glycerol, lecithin, sodium chloride, potassium chloride, calcium chloride, sodium carbonate and glucose.
