How The Blood Bag Advanced The Face Of Hospital Management
The blood bag may seem like a quite basic piece of thing, but the creation of this was a turnabout in our medical history.
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 idea of a blood transfusion for granted. But precisely, a blood transfusion is a relatively recent improvement.
Originally 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 restricting. Blood could not be stored until an appropriate anticoagulant was found. 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 injured during the last years of the 1st World War a chance to thrive.
The blood was being collected 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 possibility of contamination during the procedure.
However, with the growth by Fenwal Company of the plastic blood bag in 1953 it all 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 during the late 1930s. Although it would need many years to replace the glass storage jars, in all places, the process was begun 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 transport still needed to be discovered. Blood needs to be stored at the correct temperature and a constant temperature. Just as the mobile phone has gone from the size 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 efficient treatment we have all come to expect.
So the small blood bag has revolutionised our world, and yet many people will never hear the names of the people who are responsible for saving lives every minuet of every day.
