Abstract

A blood collection device includes a housing and an interface. The blood collection device includes at least one blood collection container engaged with the interface and at least one lancet coupled to the interface. The at least one lancet extends or is configured to extend from the interface. The at least one lancet is configured to pierce tissue. The blood collection device also includes an absorbent material integrated with the housing. The absorbent material is configured to absorb fluids emanating from the tissue after the at least one lancet pierces the tissue.

Claims

1. A blood collection device, comprising:

a housing having an interface;

at least one blood collection container engaged with the interface;

at least one lancet coupled to the interface and extending or configured to extend from the interface, the at least one lancet configured to pierce tissue; and

an absorbent material integrated with the housing, the absorbent material configured to absorb fluids emanating from the tissue after the at least one lancet pierces the tissue.

2. The blood collection device of claim 1, wherein the housing has an inner surface that defines an inner space for receiving a finger, wherein the absorbent material disposed along the inner surface.

3. The blood collection device of claim 2, wherein the at least one lancet is configured to extend into the inner volume of the housing.

4. The blood collection device claim 1, wherein the housing is sized to hold at least a portion of the at least blood collection container.

5. The blood collection device of claim 1, wherein the housing defines a skin contact side, and the absorbent material is disposed on the skin contact side of the housing.

6. The blood collection device of claim 1, wherein the skin contact side defines an outer perimeter, wherein the absorbent material is disposed at least partially along the outer perimeter.

7. The blood collection device of claim 1, wherein the absorbent material defines a ring shape around the housing.

8. The blood collection device of claim 1, wherein the absorbent material has one of circular shape, a rectilinear shape, or polyhedral shape.

9. The blood collection device of claim 1, wherein the absorbent material is bonded to the housing.

10. The blood collection device of claim 1, wherein the absorbent material is attached to the housing with a clamp.

11. The blood collection device of claim 1, wherein the absorbent material is knit, a woven, or a nonwoven fabric material.

12. The blood collection device of claim 1, wherein the absorbent material comprises cotton fibers, regenerated cellulose fibers, or a blend of cotton fibers and regenerated cellulose fibers.

13. The blood collection device of claim 1, further comprising an actuator configured to cause the at least one lancet to move between a retracted position, where the at least one lancet is withdrawn in the housing, and an extended position, where the at least one lancet extends outward from the skin contact side of the housing.

14. The blood collection device of claim 1 wherein the at least one lancet is two lancets.

15. The blood collection device of claim 1, wherein the at least one blood collection container is a first blood collection container and a second blood collection container.

16. The blood collection device of claim 15, wherein the first blood collection container and the second blood collection container are different.

17. The blood collection device of claim 1, wherein the at least one blood collection container is coupled to the housing with the cap.

18. The blood collection device of claim 17, wherein the at least one blood collection container is removable from the housing with the cap or without the cap leaving the cap coupled to the housing.

19. The blood collection device of claim 16, wherein the at least one lancet is a first lancet associated with the first blood collection container and a second lancet associated with the second blood collection container.

25. The blood collection device of claim 1, wherein the absorbent material is adhesively bonded to the housing.

20. A blood collection device, comprising:

a housing having an outer surface, an inner surface opposite the outer surface, and internal space defined by the inner surface, and an interface, the inner surface defining a skin contact portion;

at least one blood collection container engaged with the interface;

at least one lancet coupled to the interface and extending or configured to extend from the interface into the internal space of the housing, the at least one lancet configured to pierce tissue; and

an absorbent material integrated with the housing, the absorbent material configured to absorb fluids emanating from the tissue after the at least one lancet pierces the tissue.

21. The blood collection device of claim 20, wherein the at least one lancet is configured to extend into the inner volume of the housing.

22. The blood collection device of claim 20, wherein the housing is sized to hold at least a portion of the at least blood collection container.

23. The blood collection device of claim 20, wherein the housing defines an outer perimeter, wherein the absorbent material is disposed at least partially along the outer perimeter.

24. The blood collection device of claim 20, wherein the absorbent material defines a ring shape around the housing.

26. The blood collection device of claim 20, further comprising an actuator configured to cause the at least one lancet to move between a retracted position, where the at least one lancet is withdrawn in the housing, and an extended position, where the at least one lancet extends outward from the skin contact side of the housing.

27. The blood collection device of claim 20, wherein the at least one lancet is two lancets.

28. The blood collection device of claim 20, wherein the at least one blood collection container is a first blood collection container and a second blood collection container.

29. The blood collection device of claim 20, wherein the first blood collection container and the second blood collection container are different.

30. The blood collection device of claim 20, wherein the at least one blood collection container is coupled to the housing with the cap.

31. The blood collection device of claim 30, wherein the at least one blood collection container is removable from the housing with the cap or without the cap leaving the cap coupled to the housing.
