Here is some literature in the 2006 Journal of the American Society of Extra-Corporreal Technology
Title: Use of the Hemobag for Modified Ultrafiltration in a Jehovah's Witness Patient Undergoing Cardiac Surgery.
The article describes the hook up to a 67 year old JW patient. The article describes how a tube and pressure are used to keep the bag connected to the patient.
This process was banned by the JW leadership up until the late 1980s. Now it is promoted by the JW leadership. Of course they try and tell us this is a no blood technique when in fact if one looks close enough it is a transfusion of one's one blood.
Does anyone want to ask just how many people had to die before the 1980s until some guy decided to change his mind?
If this truly is a bible based doctrine, where in the Bible does it say it is okay to have blood out of your body and then re-transfused back into the body as long as a plastic tube medium is used and connected between the human and the machine but if there is no tube attachment and your own blood is stored before the procedure it is banned?
If this truly is a bible based doctrine where in the Bible does it say you are allowed to break the tube connection for blood testing and then retransfuse the blood back into the body but you are not allowed to have your own blood stored before an operation?
