Basics of apheresis and equipment

Apheresis is a method of obtaining one or more blood components by machine processing of whole blood in which the residual components are returned to the donor or patient during or at the end of the process. To achieve this, the desired blood component is separated from the whole blood using centrifugal, filtration and or adsorption techniques. Although the apheresis equipment from various manufacturers look from the outside very different, the working is rather similar with separation in a one-use disposable, connected with bacterial filters to the machine, and various safety features to achieve optimal safety for donor / patient, operator and product.
