Abstract

A device for obtaining a biological sample, such as a capillary blood collection device, that has the ability to lance and squeeze the finger, collect the sample, stabilize the sample, and subsequently dispense the sample in a controlled manner is disclosed. The device also simplifies and streamlines the capillary blood collection by eliminating workflow variabilities which are typically associated with low sample quality including hemolysis and micro-clots.

First claim

What is claimed is:

1. A device for obtaining a blood sample, the device comprising:
a holder for receiving a sample source, the holder having an actuation portion and a port;
a lancet housing secured within the port, the lancet housing having an inlet and an interior;
a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within the interior and a puncturing position wherein at least a portion of the puncturing element extends through the inlet; and
a container removably connectable to a portion of the lancet housing, the container defining a collection cavity,
wherein the actuation portion is configured to be transitioned by a user between a first position in which the holder defines a first elliptical shape and a second position in which the holder defines a second elliptical shape, and
wherein the second elliptical shape is smaller than the first elliptical shape in at least one direction.

2. The device of claim 1 , wherein the actuation portion includes a contact member.

3. The device of claim 2 , wherein the actuation portion is transitionable between a first position in which the contact member is in a disengaged position and a second position in which the contact member is in an engaged position.

4. The device of claim 3 , wherein, with the contact member in the engaged position, the contact member exerts a pressure on the sample source.

5. The device of claim 1 , wherein the actuation portion includes a pumping member for applying pressure to the sample source.

6. The device of claim 5 , wherein the pumping member comprises a pair of opposed tabs.

7. The device of claim 1 , wherein the sample source is a finger.

8. The device of claim 7 , wherein, with the finger received within the holder, the port is in communication with a portion of the finger.

9. The device of claim 8 , wherein the lancet housing includes an outlet.

10. The device of claim 9 , wherein, with the container connected to the lancet housing, the outlet of the lancet housing is in fluid communication with the collection cavity of the container.

11. The device of claim 10 , wherein, with the finger received within the holder and the puncturing element in the puncturing position, the puncturing element lances the finger to draw the blood sample.

12. The device of claim 11 , wherein the blood sample flows through a hollow needle to the outlet to the collection cavity.

13. The device of claim 8 , further comprising a capillary tube.

14. The device of claim 13 , wherein, with the container connected to the lancet housing, the capillary tube is in fluid communication with the inlet of the lancet housing and the collection cavity of the container.

15. The device of claim 14 , wherein, with the finger received within the holder and the puncturing element in the puncturing position, the puncturing element lances the finger to draw the blood sample.

16. The device of claim 15 , wherein the blood sample flows through the capillary tube to the collection cavity.

17. The device of claim 1 , wherein the puncturing element comprises a hollow needle.

18. The device of claim 1 , wherein, with the container connected to the lancet housing, the longitudinal axis of the port, the lancet housing, and the container are aligned.

19. The device of claim 1 , wherein, with the container connected to the lancet housing, the longitudinal axis of the lancet housing is at an angle to the longitudinal axis of the container.

20. A device for obtaining a blood sample, the device comprising:
a holder for receiving a sample source, the holder having an actuation portion and a port, wherein the actuation portion includes a pumping member for applying pressure to the sample source,
wherein the actuation portion is transitionable by a user between a first position in which the holder defines a first elliptical shape and a second position in which the holder defines a second elliptical shape, wherein the second elliptical shape is smaller than the first elliptical shape in at least one direction.

21. The device of claim 20 , wherein the actuation portion includes a contact member.

22. The device of claim 21 , wherein the actuation portion is transitionable between the first position in which the contact member is in a disengaged position and the second position in which the contact member is in an engaged position.

23. The device of claim 22 , wherein, with the contact member in the engaged position, the contact member exerts a pressure on the sample source.

24. The device of claim 20 , wherein the pumping member comprises a pair of opposed tabs.

25. The device of claim 20 , wherein the sample source is a finger.

26. The device of claim 25 , wherein, with the finger received within the holder, the port is in communication with a portion of the finger.

27. The device of claim 20 , wherein the holder includes a stability extension portion.

28. The device of claim 20 , further comprising:
a lancet housing removably connectable to the port, the lancet housing having an inlet and an interior; and
a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within the interior and a puncturing position wherein at least a portion of the puncturing element extends through the inlet.

29. The device of claim 28 , further comprising a container removably connectable to the port, the container defining a collection cavity.
