This apparatus was created in 1934 by Dr. P. Jouvelet and Dr. L. Henry to enable blood transfusion “from arm to arm,” from the donor to the receiver. The left panel shows a contemporary advertisement written in French: Blood transfusion directly from the donor to the receiver: withdrawal and injection, using a single syringe . The risk of clotting was very limited and there was no possibility for air entry. A flow counter (in cc) provided the total amount of blood transfused. From 1950 to 1975, it was an essential tool of the French anesthesiologist in the operating room, not for direct “arm to arm” blood transfusion but as a rapid infusion and/or transfusion device. The rate depended on the manual rotation velocity through the handle. This apparatus became electrically driven but this increased the risk of air embolism when the infusion vial was empty. This is the reason why an air detection device located in the output intravenous line was introduced.
