Abstract

A point of care fluid testing system for determining properties of a fluid comprises a patient connection, a primary fluid routing portion, a pump, a secondary fluid routing portion, and a flushing fluid connection. The patient connection connects the system to a patient. The primary fluid routing portion has a pump region, a fluid transfer region, and an in-line testing region. The pump region pumps the fluid sample from the patient to the testing portion and back to the patient. The in-line testing region evaluates a first characteristic of the fluid sample. The fluid transfer region transmits a portion of the fluid sample out of the primary fluid routing portion. The secondary fluid routing portion includes an off-line testing portion that receives the portion of the fluid sample transmitted from the fluid transfer region. The off-line testing portion evaluates a second characteristic of the fluid sample.
