Abstract

A blood sampling device useful for collecting a blood sample from a separate vascular access device is described herein. The blood sampling device includes a body shaped and sized for partial insertion into a separate vascular access device. The body includes a reservoir defined within the body, which has an internal volume sufficient to contain enough blood for use in a diagnostic blood test. The body also includes a gas permeable vent disposed on the body, in which the gas permeable vent is in gaseous communication with the reservoir. When connected to a separate vascular access device the blood sampling device collects a blood sample as blood flows into the reservoir from the separate vascular access device and as gases pass out the reservoir via the gas permeable vent.

Claims

1. A blood sampling device, comprising:

a body shaped and sized for partial insertion into a separate vascular access device;

a reservoir of one or more chambers, defined within the body, the reservoir having an internal volume sufficient to contain enough blood for use in a diagnostic blood test; and

a gas permeable vent disposed on the body, the gas vent in gaseous communication with the reservoir.

2. The blood sampling device of claim 1, further comprising a diagnostic reagent disposed within at least one chamber of the reservoir.

3. The blood sampling device of claim 1, further comprising an on-board diagnostic cartridge in fluid communication with at least one chamber of the reservoir.

4. The blood sampling device of claim 1, the body comprising a compressible portion that is shaped and sized to eject the contents from at least one chamber of the reservoir when compressed.

5. The blood sampling device of claim 1, wherein the reservoir includes at least two chambers.

6. The blood sampling device of claim 1, wherein the reservoir includes a blood preservative in at least one chamber.

7. The blood sampling device of claim 1, wherein the body includes an indicator of elapsed time since blood sampling.

8. The blood sampling device of claim 1, wherein the reservoir includes a distal opening, the distal opening in fluid communication with the separate vascular access device when the body is partially inserted into the separate vascular access device.

9. The blood sampling device of claim 8, wherein the body includes a male luer adapter shaped and sized for insertion into the separate vascular access device, and wherein the distal opening is a distal opening of the male luer adapter.

10. The blood sampling device of claim 8, wherein the distal opening includes a wicking material disposed therein.

11. The blood sampling device of claim 8, wherein the distal opening includes a flow restrictor.

12. The blood sampling device of claim 1, wherein the body includes a luer adapter for insertion into the separate vascular access device.

13. A blood sampling device, comprising:

a body shaped and sized for partial insertion into a separate vascular access device;

a reservoir of one or more chambers defined within the body, each chamber having an internal volume of at least 0.1 μ

L;

a gas permeable vent disposed on the body, the gas vent in gaseous communication with the reservoir;

a diagnostic component in fluid communication with the reservoir.

14. The blood sampling device of claim 13, wherein the diagnostic component includes an on-board diagnostic cartridge in fluid communication with at least one chamber of the reservoir.

15. The blood sampling device of claim 13, wherein the diagnostic component includes a diagnostic reagent disposed within at least one chamber of the reservoir.

16. The blood sampling device of claim 13, wherein the reservoir includes multiple chambers, and wherein at least two of the multiple chambers includes a separate diagnostic component.

17. The blood sampling device of claim 13, wherein the diagnostic component includes a preservative.

19. The blood sampling device of claim 17, wherein the reservoir has an internal volume of less than 10 mL.

20. The blood sampling device of claim 17, wherein the reservoir includes a blood preservative.

18. A blood sampling device, comprising:

a body shaped and sized for partial insertion into a separate vascular access device, the body having a compressible portion;

a reservoir defined within the body, the reservoir having an internal volume of at least 0.1 μ

L, the compressible portion of the body being shaped and sized to eject at least a portion of the contents of the reservoir when compressed; and

a gas permeable vent disposed on the body, the gas vent in gaseous communication with the reservoir.
