Blood transfusion has been known for a very long time. This process involves taking blood from one person - a donor - to give it to another person, who needs it. At first, only the so-called autotransfusion was used in medical practice, when blood was taken from a patient and given back to this very same patient, but only much later. Such a technique was used before complex surgical operations because a great amount of blood was needed for such operations. At those times people knew nothing about blood groups, so only autotransfusion was possible. But much later Austrian Karl Landsteiner discovered that there are four different groups of blood. Later discoveries in this sector allowed understanding more about blood groups and how blood of one patient can be given to another. That was the actual start of the transfusion. Different sorts of blood banks started to appear. All that had improved the medicine greatly. But along with transfusion, a great number of problems also came. There are two main problems related to blood transfusion. The first one is that during blood transfusion a virus infection can be easily transmitted. Another serious problem of blood transfusion is that although different blood studies had been performed there is still a risk of the occurrence of different hemolytic reactions. And what makes this problem even bigger, many of such reactions can appear weeks or months after the blood transfusion. That is why, autotransfusion is still widely used in the modern medicine. Autotransfusion is mainly used as preoperational donation. This way doctors can be positively sure that there will be no hemolytic reactions, and the possibility of different infections is also excluded. So-called direct autotransfusion is also used in different sorts of drainage systems. In these systems patient blood is purified with different filters and then it (or only its components in some cases) is returned to the patient. Very sophisticated equipment is used in all these cases of autotransfusion, transfusion and blood storage. And being very complex many blood transfusion sets are pretty expensive. But there is a way to save some money even in that sector of medicine. But buying blood transfusion set exporters from different countries, like India and China, it is possible to save up to 50 percents on blood transfusion set costs. This means that it is possible to buy twice as much as with the same sum of money. For some clinics such an opportunity can be very important. But there is a strong belief that blood transfusion set exporters usually offer a low quality product. But, in fact, it is not so. If you want to get a high quality equipment, you only need to order it from blood transfusion set exporter, which has been ISO 9000 certified. This ISO standard guarantees the perfection of medical equipment all over the world. So, if the ISO 9000 standard certification is provided, then you can get medical equipment from blood transfusion set exporter at much lower prices than it is usually offered in Europe or the United States. On the internet you can even find a directory of blood transfusion set exporters with the description of products they offer.
