Blood donor lying down,with a tube inserted in his forearm to collect blood. He is squeezing a rubber ball to encourage good circulation in his arm. The collected blood is drained into a bag (not seen) that contains an anti-coagulant so the blood remains liquid. The bag is suspended on a set of scales (upper right) so that the nurses (phlebotomists) can monitor the amount collected. Typically a full bag will hold 475 millilitres. Donor blood is given to patients in transfusions to replace lost blood,for example during surgery or after accidents | |
