Abstract

A medical treatment process and system, in which a patient fluid is subjected to extracorporeal handling and treatment prior to administration to the patient, is provided. The system includes two or more treatment units which successively handle the fluid, and a token associated with the patient. The token includes a patient identification and, as the treatment proceeds, more information is added to the token as the fluid moves around the system until the token contains a record of the treatment conducted on the sample, the times of various treatments, and a verification that treatment has been conducted in accordance with pre-determined criteria. The token, provided it contains information verifying the identity of the patient and treatment according to specification, allows administration of the treated fluid to the patient and provides an audit record of the treatment.
