Abstract

Claims (43)

1. A device comprising:

an inlet port configured for receiving a blood sample;

an outlet port;

a chamber connected to the inlet port and being configured to collect a first portion of the blood sample, the chamber having a blood impermeable membrane configured to facilitate the chamber collecting the first portion of the blood sample;

a housing, separate from the blood impermeable membrane; and

a sampling channel connected with the inlet port and configured to convey a subsequent portion of the blood sample to the outlet port.

2. The device in accordance with claim 1 , wherein the blood impermeable membrane is configured to cause the first portion of the blood sample to back up into the chamber following application of a drawing force applied from the outlet port.

3. The device in accordance with claim 1 , wherein the device is configured such that, when a drawing force is applied at the outlet port, the first portion of the blood sample is drawn into the chamber to contact a material that is blood impermeable.

4. The device in accordance with claim 1 , further comprising a valve configured to initially close off the sampling channel.

5. The device in accordance with claim 1 , further comprising a valve configured to initially close off the sampling channel until the first portion of the blood sample is in the chamber.

6. The device in accordance with claim 1 , further comprising a valve that is configured to initially close off the sampling channel until the first portion of the blood sample is in the chamber and is further configured such that, upon release, the subsequent portion of the blood sample will bypass the chamber and flow through the sampling channel toward the outlet port.

7. The device in accordance with claim 4 , wherein the valve is configured to pinch, shunt, bend or otherwise close off the sampling channel before the first portion of the blood sample is collected in the chamber.

8. The device in accordance with claim 1 , wherein the housing defines the inlet port, the sampling channel, and the outlet port.

9. The device in accordance with claim 1 , further comprising a patient needle and a sample collection device.

10. The device in accordance with claim 1 , the chamber having a volume configured to be sufficient to collect the first portion of the blood sample that is more prone to contamination and also to minimize an amount of blood to be sequestered.

11. The device in accordance with claim 1 , wherein the chamber has a volume of less than 1.5 cubic centimeters.

12. A device comprising:

an inlet port configured for receiving blood;

an outlet port;

a chamber connected to the inlet port and being configured to collect a first portion of the blood, the chamber comprising a flexible blood impermeable membrane that allows the chamber to collect the first portion of the blood; and

a sampling channel connected with the inlet port and configured to convey a subsequent portion of the blood to the outlet port.

13. The device in accordance with claim 12 , wherein the flexible blood impermeable membrane is configured to cause the first portion of the blood to back up into the chamber following application of a drawing force applied from the outlet port.

14. The device in accordance with claim 12 , wherein the device is configured such that, when a drawing force is applied at the outlet port, the first portion of the blood is drawn into the chamber to contact a material that is blood impermeable.

15. The device in accordance with claim 12 , further comprising a valve configured to initially close off the sampling channel.

16. The device in accordance with claim 12 , further comprising a valve configured to initially close off the sampling channel until the first portion of the blood is in the chamber.

17. The device in accordance with claim 12 , further comprising a valve that is configured to initially close off the sampling channel until the first portion of the blood is in the chamber and is further configured such that, upon release, the subsequent portion of the blood will bypass the chamber and flow through the sampling channel toward the outlet port.

18. The device in accordance with claim 15 , wherein the valve is configured to pinch, shunt, bend or otherwise close off the sampling channel before the first portion of the blood is collected in the chamber.

19. The device in accordance with claim 12 , further comprising a patient needle and a sample collection device.

20. The device in accordance with claim 12 , the chamber having a volume configured to be sufficient to collect the first portion of the blood that is more prone to contamination and also to minimize an amount of blood to be sequestered.

21. A device comprising:

an inlet port configured for receiving blood;

an outlet port;

a chamber connected to the inlet port, the chamber having a blood impermeable membrane and being configured to collect a first portion of the blood; and

a sampling channel connected with the inlet port and configured to convey a subsequent portion of the blood to the outlet port.

22. The device in accordance with claim 21 , wherein the blood impermeable membrane is configured to cause the first portion of the blood to back up into the chamber following application of a drawing force applied from the outlet port.

23. The device in accordance with claim 21 , wherein the device is configured such that, when a drawing force is applied at the outlet port, the first portion of the blood is drawn into the chamber to contact a material that is blood impermeable.

24. The device in accordance with claim 21 , further comprising a valve configured to initially close off the sampling channel.

25. The device in accordance with claim 21 , further comprising a valve configured to initially close off the sampling channel until the first portion of the blood is in the chamber.

26. The device in accordance with claim 21 , further comprising a valve that is configured to initially close off the sampling channel until the first portion of the blood is in the chamber and is further configured such that, upon release, the subsequent portion of the blood will bypass the chamber and flow through the sampling channel toward the outlet port.

27. The device in accordance with claim 24 , wherein the valve is configured to pinch, shunt, bend or otherwise close off the sampling channel before the first portion of the blood is collected in the chamber.

28. The device in accordance with claim 21 , further comprising a patient needle and a sample collection device.

29. The device in accordance with claim 21 , the chamber having a volume configured to be sufficient to collect the first portion of the blood that is more prone to contamination and also to minimize an amount of blood to be sequestered.

30. The device in accordance with claim 21 , wherein the chamber has a volume of less than 1.5 cubic centimeters.
