AUTOMATED POINT-OF-CARE FLUID TESTING DEVICE AND METHOD OF USING THE SAME
First Claim
1. A point of care fluid testing system for determining properties of a fluid comprising:
- a patient connection adapted to connect the system to a patient to collect a fluid sample;
a primary fluid routing portion having a pump region, a fluid transfer region, and an in-line testing region, the pump region adapted to pump the fluid sample from the patient to the testing portion, and to pump a substantial portion of the fluid sample from the primary fluid routing portion back to the patient following testing, the in-line testing region being adapted to evaluate at least a first characteristic of the fluid sample, and the fluid transfer region being adapted to allow a portion of the fluid sample to be transmitted out of the primary fluid routing portion;
a pump that interacts with the pump region of the primary fluid routing portion;
a secondary fluid routing portion including an off-line testing portion adapted to receive the portion of the fluid sample transmitted out of the primary fluid routing portion via the fluid transfer region, the off-line testing portion being further adapted to evaluate a second characteristic of the fluid sample; and
a flushing fluid connection adapted to connect the system to a flushing fluid to flush the system following the pumping of the fluid sample back to the patient.

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.

15. A method of evaluating at least two characteristics of a fluid sample of a patient comprising:
-
attaching a fluid connector to a patient; providing a fluid testing system for determining properties of a fluid, the fluid testing system having a patient connection;
a primary fluid routing portion having a pump region, a fluid transfer region, and an in-line testing region;
the testing system further having an secondary fluid routing portion including an off-line testing portion; and
a communications device;connecting the fluid connector to the patient connection of the testing system; collecting a fluid sample from the patient via the fluid connector and the patient connection using the pump region of the testing system to draw the fluid sample from the patient to the primary fluid routing portion of the testing device; analyzing the fluid sample in the in-line testing region of the primary fluid routing portion to determine a first characteristic of the fluid sample; transferring a portion of the fluid sample through the fluid transfer portion of the primary fluid routing portion to the off-line testing portion of the secondary fluid routing portion; determining a second characteristic of the fluid sample in the off-line testing portion; returning the remaining portion of the fluid sample to the patient, following the act of transferring, via the fluid connector and the patient connection using the pump region of the testing system to pump the fluid sample back into the patient. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A disposable primary fluid routing portion comprising:
-
a pump region adapted to interact with a reversible pump to draw a fluid sample into a disposable testing portion for testing and to pump most of the fluid sample out of the disposable testing portion back in the direction from which the fluid sample entered the pump region; a fluid transfer region adapted to allow a portion of the fluid sample to be transmitted through the fluid transfer region and out of the primary fluid routing portion; and an in-line testing region, the in-line testing region having an analyzer adapted to analyze the fluid sample to determine a first characteristic of the fluid sample. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
