Abstract

Devices and methods for mixing a clotting agent with other inputs such as blood, blood derived product, bone marrow, and/or bone marrow derived product to form a congealed mixture.

Claims

1. A mixing device comprising a passageway for mixing a clotting agent with an input material, a first container containing the clotting agent, a second container containing the input material, the containers in communication with the passageway, wherein a mixer portion of the passageway has a turbulent flow inducing shape.

2. The mixing device of claim 1 further comprising:

(a) a body comprising the passageway and a base for resting on a flat surface (b) the first container containing the clotting agent in communication with the passageway at a first input port on the body, (c) the second container containing the input material in communication with the passageway at a second input port on the body; and

(d) a receiving container in communication with the passageway at an output port on the body, for removing a mixture of the clotting agent and the input material;

wherein

the passageway through the body connects the first input port, the second input port, and the output port, and comprises the mixer portion with the turbulent flow inducing shape.

4. The mixing device of claim 1, in which the mixer portion comprises an hourglass-shaped tubular portion.

5. The mixing device of claim 1, in which the mixer portion comprises a shape of repeating hourglasses.

6. The mixing device of claim 1, in which the mixer portion comprises a first portion and a second portion, in which a diameter of the first portion is greater than a diameter of the second portion.

8. The mixing device of claim 1, in which the mixer portion comprises a tubular portion having a circular cross section.

9. The mixing device of claim 1, in which the mixer portion comprises a tubular portion having a cross section shape that varies along a length of the portion.

10. The mixing device of claim 1, in which the mixer portion comprises a first portion and a second portion, in which a width of the first portion is greater than a width of the second portion.

11. The mixing device of claim 1, in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a width of the first portion is greater than a width of the second portion and the width of the second portion is less than a width of the third portion.

12. The mixing device of claim 1, in which the mixer portion comprises a first portion and a second portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion.

13. The mixing device of claim 1, in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion and the cross sectional area of the second portion is less than a cross sectional area of the third portion.

14. The mixing device of claim 1, in which the mixer comprises a first portion, a second portion, a third portion, and a fourth portion in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion, the cross sectional area of the second portion is less than a cross sectional area of the third portion, and the cross sectional area of the third portion is greater than a cross sectional area of the fourth portion.

16. The mixing device of claim 1, in which the mixer portion comprises a portion having a tortuous shape.

17. The mixing device of claim 2, in which the mixer portion comprises an hourglass-shaped tubular portion.

18. The mixing device of claim 2, in which the mixer portion comprises a shape of repeating hourglasses.

19. The mixing device of claim 2, in which the mixer portion comprises a first portion and a second portion, in which a diameter of the first portion is greater than a diameter of the second portion.

20. The mixing device of claim 2, in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a diameter of the first portion is greater than a diameter of the second portion and the diameter of the second portion is less than a diameter of the third portion.

22. The mixing device of claim 2, in which the mixer portion comprises a tubular portion having a cross section shape that varies along a length of the portion.

23. The mixing device of claim 2, in which the mixer portion comprises a first portion and a second portion, in which a width of the first portion is greater than a width of the second portion.

24. The mixing device of claim 2, in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a width of the first portion is greater than a width of the second portion and the width of the second portion is less than a width of the third portion.

25. The mixing device of claim 2, in which the mixer portion comprises a first portion and a second portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion.

26. The mixing device of claim 2, in which the mixer portion comprises a first portion, a second portion, and a third portion, in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion and the cross sectional area of the second portion is less than a cross sectional area of the third portion.

27. The mixing device of claim 2, in which the mixer comprises a first portion, a second portion, a third portion, and a fourth portion in which a cross sectional area of the first portion is greater than a cross sectional area of the second portion, the cross sectional area of the second portion Is less than a cross sectional area of the third portion, and the cross sectional area of the third portion is greater than a cross sectional area of the fourth portion.

29. The mixing device of claim 2, in which the mixer portion comprises a portion having a tortuous shape.

3. A method of mixing a clotting agent with an input material, comprising:

providing a mixing device comprising a passageway, a first container of the clotting agent in communication with the passageway, and a second container of the input material in communication with the passageway; and

passing the clotting agent and the input material at approximately the same time through a mixer portion of a passageway with a turbulent flow inducing shape.
