How The Blood Bag Revolutionized The Face Of Healthcare System
Without the advantage of a blood transfusion there are many operations which could not be carried out and would never have been attempted. We take the concept of a blood transfusion for granted. But actually, a blood transfusion is a somewhat recent development. Initially there was no method to store blood, so a transfusion had to be absolutely from one vein into another vein. This was of course very limiting. Blood could not be preserved until a suitable anticoagulant was discovered. Richard Lewison invented this in 1915; sodium citrate. Within just a couple of years blood was being donated and stored for few days at a time. This gave many of those wounded during the last years of the First World War an opportunity to survive. The blood was being donated and stored in glass bottles. It was already discovered that blood could be divided into its component parts of blood plasma and packed cells; but this was very risky due to the chance of contamination during the process. Nonetheless, with the development by Fenwal Company of the plastic blood bag in 1953 everything changed. This was a simple way to store and transfer blood with minimal contamination risk; abruptly so much more was possible. The first blood banks were set up in the Soviet Union, United States and Europe in the late 1930s. Although it would take many years to upgrade the glass storage jars, in all areas, the process was started and immediately there were increasingly more uses of blood transfusions and more daring surgeries were happening with this extra support. So now the blood could be obtained, divided, and stored; but transportation still needed to be conquered. Blood needs to be stored at the right temperature and a consistent temperature. Just as the mobile phone has gone from the volume and weight of brick to something not much larger than a credit card; so the transport of blood has progressed.There are now thermal blood carrying bags which allow medics to take blood to where ever it is required. These are essential for the quick and effective treatment we have all come to expect. So the little blood bag has revolutionised our planet, and yet many people will never know the names of the people who are contributing for saving lives every minuet of every day.
