PRESSURE-BASED LEAK DETECTION IN EXTRACORPOREAL BLOOD TREATMENT APPARATUS

摘要

The extracorporeal blood treatment apparatus described herein include components configured to detect liquid leaking from one or more liquid circuits in the extracorporeal blood treatment apparatus and methods of detecting liquid leaks in extracorporeal blood treatment apparatus. The components used to detect leaks include one or more remote pressure ports connected to one or more local pressure ports on one or more pressure sensors by one or more fluid-filled pressure lines. The fluid in the pressure lines transmits pressure exerted on a remote pressure port by any collected liquid to the local pressure port of the pressure sensor.
