Abstract

An integrated disposable set for dialysis or ultrafiltration treatment of blood is disclosed that includes a memory 'key' chip. The key contains information relating to the set, including calibration for sensors, model and date of manufacture and a proprietary secret code to prevent unauthorized duplication of a circuit. The key is activated when treatment of a patient begins to prevent reuse of the set and a delay in use of the set that is too long. Patient data and operational information can be stored in the key during treatment. The key can be returned to the manufacturer or entered into hospital database for analysis. The key is preferably an EEPROM chip that can be embedded in an integral circuit sensor or a separate plug in device, such as a code card.
