Abstract

The present invention relates generally to systems, apparatuses, and methods for obtaining a fluid sample from a patient. In particular, the present invention relates to a various types of fluid access interfaces for enabling contact between a patient blood sample and blood parameter sensors for the measurement of physiological parameters and blood constituents.

Claims

1. A blood constituent measuring device comprising:

at least one transfer mechanism comprising;

a fluid access interface configured to automatically interface with a patient blood access line at a sampling port to access a blood sample therefrom; and

a transfer tube configured to receive a blood sample from the patient blood access line;

wherein the transfer tube comprises a flexible portion configured to be contracted to direct the blood sample to a test substrate.

2. The device of claim 1, wherein the at least one transfer mechanism is movable with respect to the sample port.

3. The device of claim 2, wherein the at least one transfer mechanism comprises a plurality of transfer mechanisms and a plurality of test substrates, wherein each transfer mechanism is configured to transfer a blood sample to a corresponding test substrate.

4. The device of claim 3, further comprising a housing containing said plurality of test substrates.
