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 fluid access interface configured to automatically interface with a patient blood access line at a sampling port to access a blood sample therefrom and to separate the blood sample from the patient blood access line, said at least one fluid access interface comprising a container configured to contain the blood sample separated from the patient blood access line;

a plurality of test substrates, wherein the at least one fluid access interface is configured to transfer each of a plurality of blood samples to each of the plurality of test substrates, wherein the at least one fluid access interface comprises a plurality of fluid access interfaces wherein each fluid access interface is configured to transfer a blood sample to a corresponding test substrate of the plurality of test substrates; and

at least one pump element configured to direct the separated blood sample to the corresponding test substrate.

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

3. The device of claim 1, wherein the device is configured to transfer the blood samples to the corresponding test substrates using a predetermined schedule.

4. The device of claim 1, further comprising a housing containing said plurality of test substrates.

5. The device of claim 1, further comprising an infusion source coupled to the patient blood access line.

6. The device of claim 1, wherein the at least one pump element comprises a flexible portion configured to direct the separated blood sample to the test substrate.

7. The device of claim 6, wherein the flexible portion is configured to contract.

8. The device of claim 7, wherein the flexible portion is configured to expand.

9. The device of claim 1, wherein the container comprises a tube.

10. The device of claim 1, wherein the container comprises a valve.

11. The device of claim 1, wherein the container comprises a cylinder.

12. The device of claim 1, wherein the test substrate comprises a glucose test substrate.

13. The device of claim 1, wherein the at least one pump element is further configured to pull the blood sample from the sampling port.
