Abstract

A biological fluid sampling device for collecting a blood sample from a separate vascular access device and for ejecting a portion of the collected sample to a point-of-care testing device for analysis is provided. The biological fluid sampling device includes a body enclosing a reservoir. The reservoir has an internal volume sufficient to contain enough blood for use in a diagnostic test. The sampling device further includes: an access lumen extending from a distal end of the body for establishing fluid communication between a separate vascular access device and the reservoir; an outflow lumen also in fluid communication with the reservoir; and a removable vented cap attached to the outflow lumen including a gas permeable vent in gaseous communication between the reservoir and ambient air. In addition, several sample and transfer devices are provided for obtaining a sample from a subject and transferring the sample to a point-of-care testing device.

Claims

1. A biological fluid sampling device engageable with a separate vascular access device, comprising:

a housing enclosing a biological fluid reservoir, the reservoir defining an interior;

an access lumen extending from a portion of the housing and establishing fluid communication between the separate vascular access device and the interior of the reservoir;

an outflow lumen extending from a portion of the housing, the outflow lumen having a first end provided in fluid communication with the interior of the reservoir and a second end; and

a vented cap removably disposed over the second end of the outflow lumen, the vented cap comprising a gas permeable vent in gaseous communication between the interior of the reservoir and an ambient environment.

2. The biological fluid sampling device of claim 1, further comprising a luer lock at least partially surrounding the access lumen.

3. The biological fluid sampling device of claim 1, wherein the vented cap comprises a luer lock for insertion in the outflow lumen.

4. The biological fluid sampling device of claim 3, wherein the vented cap comprises a fastener for removably connecting a portion of the cap to a portion of the housing.

5. The biological fluid sampling device of claim 1, wherein the interior of the reservoir is configured for receiving a fluid sample therein.

6. The biological fluid sampling device of claim 5, wherein the housing comprises a compressible portion, wherein compression of the compressible portion expels the fluid sample from the interior of the reservoir through the access lumen.

7. The biological fluid sampling device of claim 1, wherein the access lumen is disposed at a distal end of the housing and the outflow lumen is disposed at a proximal end of the housing.

8. The biological fluid sampling device of claim 1, wherein the reservoir contains a sample stabilizer.

9. The biological fluid sampling device of claim 8, wherein the housing has a visual identifier which corresponds to a specific sample stabilizer.

10. The biological fluid sampling device of claim 9, wherein the visual identifier is a specific color.

11. The biological fluid sampling device of claim 1, wherein the vent comprises at least one of a porous plug, a permeable membrane, and small vent holes.

12. A biological fluid sampling and collection assembly comprising:

a biological fluid sampling device comprising;

a housing enclosing a biological fluid reservoir, the reservoir defining an interior;

an access lumen extending from a portion of the housing and establishing fluid communication between a separate vascular access device and the interior of the reservoir; and

an outflow lumen extending from a portion of the housing, the outflow lumen having a first end provided in fluid communication with the interior of the reservoir and a second end; and

a sample collection device comprising;

an adapter for accessing an interior of a sample container and for establishing fluid communication between the biological fluid reservoir and an interior of the sample container, thereby allowing fluid communication between the interior of the reservoir and the interior of the sample container; and

a flow restrictor engaged with the adapter, the flow restrictor transitionable from an open position, in which fluid communication is permitted between the biological fluid reservoir and the interior of the sample container, to a closed position, in which the biological fluid reservoir is in fluid isolation from the interior of the sample container.

13. The biological fluid sampling and collection assembly of claim 12, wherein the biological fluid reservoir contains a fluid and, wherein when the flow restrictor is in the open position, the fluid passes from the biological fluid reservoir to the interior of the sample container.

14. The biological fluid sampling and collection assembly of claim 12, wherein the flow restrictor is in the open position when the sample container is engaged with the adapter, and wherein the flow restrictor is in the closed position when the sample container is removed from the adapter.

15. The biological fluid sampling and collection assembly of claim 12, further comprising a vented cap removably disposed over the second end of the outflow lumen, the vented cap comprising a gas permeable vent in gaseous communication between the interior of the reservoir and an ambient environment.

16. The biological fluid sampling and collection assembly of claim 12, wherein the sample container is a vacuum evacuated container.

17. The biological fluid sampling and collection assembly of claim 12, further comprising the separate vascular access device in fluid communication with the access lumen.

18. The biological fluid sampling and collection assembly of claim 17, further comprising an adapter connected between the separate vascular access device and the biological fluid sampling device.

19. The biological fluid sampling and collection assembly of claim 18, wherein the adapter comprises:

a housing;

a main lumen enclosed within the housing having a main outflow port;

a side port including a side lumen extending from and in fluid communication with the main lumen; and

a valve transitionable from a first position in which fluid flow is permitted through the main lumen and fluid flow is prevented through the side lumen, to a second position in which fluid flow through both the main lumen and side lumen is permitted.

20. The biological fluid sampling and collection assembly of claim 19, wherein the valve is transitioned from the first position to the second position by insertion of a tubular member into the side lumen through the side port.
