As an effective therapy, blood transfusion has been developed for more than 100 years. In ancient times, people's understanding of blood is unknown and has no scientific basis. At the same time, blood transfusion is not hesitate to save enough, but after a long and tortuous road to development so far.
1, ancient blood transfusion
Start from the beginning of human blood transfusion, blood drinking and bloodletting. The ancient Rome gladiator in sword fighting on the field to diet the dying person's blood, to gain strength and courage from. In 1492, the Pope of Rome VIII stroke, doctors at a loss what to do.

In late fifteenth Century, was once considered the mental disorder, depression, mania and other diseases are caused by blood "toxic", which was quite popular bloodletting therapy, has been extended to sixteenth Century. The backward science and technology at that time, people lack the correct understanding of the blood, the result is saving lives as can be imagined.
Until 1616, the British physician Harvey discovered that the blood is flowing in the body, it laid the foundation for subsequent transfusion, this finding also inspired people to intravascular injection of drugs, with the help of the flow of blood to bring the drug to the body, treatment of disease, which is now known as infusion.
2, animal blood transfusion
In 1665 the British physiologist and Dr. Lower will first use a goose quill bloodletting after dying dog vein and another healthy dog artery connected by blood from the dying dog unexpectedly recovered, this finding suggests that blood transfusion can help. Pioneered the animal transfusion.
In 1667, the French doctor Denys in the same way the sheep lost to a sick boy to succeed, then he gave a healthy person willing to do the experiment lost sheep, is safe and sound, is recognized as the first successful blood transfusion in humans. However, in his calf arterial infusion there was an accident to a syphilis patient, after blood transfusion patients with fever, back pain, and a black urine, soon died, the deceased's family sued the Denys murder. Since April 17, 1668, the court shall not be approved without the approval of the Ministry of medicine of Paris. After the French parliament and the British Parliament have banned blood transfusion. In the next 150 years, once a sensation of the medical profession will No one shows any interest in blood transfusion.
3, blood loss to people
1817-1818, British obstetrician Dudley often see maternal blood loss due to Bren death, and thought of using blood transfusion to save, he carried out animal blood transfusion between success, designed a set of blood transfusion equipment (1 chairs, 1 funnels, syringes and tubes) will start in healthy people blood to bleeding a total of 10 cases of maternal treatment, except 2 cases of death to save, the remaining 8 cases in 4 cases. Because at that time did not know the blood type different blood transfusion, the red blood cell can meet the massive destruction, therefore is unable to explain after the blood transfusion some appears the lethal blood transfusion reaction, but some actually miraculously survives the phenomenon.
Nevertheless, in December 1818, 22, he was in London, the Institute of Medicine on the blood transfusion report or caused a sensation in the medical world. Since then, he has improved blood transfusion equipment, with a brass syringe and catheter extraction of healthy human blood into the patient's vein. He also pioneered a gravity transfusion device that uses gravity as a driving force for blood transfusions. The method has been used for about 100 years. The currently accepted a direct blood transfusion Bren Dudley, and as the first person to person blood to the pioneer in history.
4, blood transfusion
In 1900, Austria pathological geneticist Karl Landsteiner first discovered human red blood cell. This epoch-making discovery, for the future by blood transfusion and avoid fatal transfusion reactions caused by different blood transfusion and ensure the safety of blood transfusion, is of great significance. To this end, he won the 1930 Nobel prize in physiology, and enjoy the blood of the father's reputation.
5, according to the composition of blood transfusion
After 1927, in order to solve the problem of blood storage and transportation, convenient emergency at any time application, methods and techniques continue to explore the separation of human plasma, red blood cells, platelets and other blood components, laid the foundation for the development of component blood transfusion. Component blood transfusion is put forward by Gibson in 1959, but by the end of 1960s and early 70s, component blood transfusion is really developed, especially in the last century after the mid 70s entered a new era of component blood transfusion.
Not only the precious blood component transfusion resources are fully utilized, to "blood", but also improve the efficacy and safety of the advanced, scientific and reasonable at present is generally recognized, is a revolution in the history of blood transfusion. Nowadays, many countries in the world carry out blood transfusion, some countries regard it as one of the important signs to measure the level of medical technology in a country.
The history of blood transfusion has been developed. Blood transfusions save lives. The ancestors have such exploration and experiment of courage, only to put the blood of others to pave the way of life. You can also, please bravely hold out your arms, to hold up the sun of life!
