Apheresis Units, Therapeutic
Definition : Apheresis units designed to automate the removal of a pathologic component or toxin from the blood of a patient and/or its exchange with a replacement fluid. Typically, one or more pathologic components (e.g., antibodies, sickle cells) and/or toxins are removed and the rest of the blood is automatically reinfused. These units usually consist of a disposable pheresis set (i.e., a tubing set that connects the patient to the apheresis unit), pumps (e.g., rotary peristaltic pumps), a centrifugation chamber, bowls, filters, clamps, controls (e.g., centrifuge and pump speed, volume of solution added), alarms, and bubble detectors. Dedicated apheresis units with special centrifugation devices and/or filters are available for removal or exchange of specific blood components (e.g., lymphocytes, granulocytes) and low-density lipoprotein cholesterol.
