Abstract

Claims (27)

1. An apparatus for supporting an intraosseous device disposed at a target site in a patient, the apparatus comprising:

an inner support including a bore extending therethrough, the bore configured to receive a portion of the intraosseous device; and

an outer support including an adjustable inner diameter, the outer support configured to receive a portion of the inner support;

wherein an outer surface of the inner support includes a first engagement portion including at least one groove, an inner surface of the outer support includes a second engagement portion including at least one tooth, and the first and second engagement portions are configured to engage each other to secure the inner support in place against longitudinal and rotational displacement relative to the outer support;

wherein a reduction of the inner diameter of the outer support secures the inner support in place against the longitudinal and/or rotational displacement; and

wherein the reduction of the inner diameter of the outer support results in the at least one tooth protruding into the at least one groove to hold the inner support in place against the longitudinal and/or rotational displacement.

2. The apparatus according to claim 1 , wherein the outer support includes a snap-grip operable to reduce the diameter of the outer support as the snap-grip is squeezed closed.

3. The apparatus according to claim 2 , wherein the snap-grip is configured to restrain the outer support from increasing a distance between opposing teeth of the at least one tooth once reduced.

4. The apparatus according to claim 3 , wherein the snap-grip is configured to release the outer support as the snap-grip is twisted open.

5. The apparatus according to claim 1 , wherein the inner diameter of the outer support is configured to reduce in response to a force applied to the outer diameter of the outer support.

6. The apparatus according to claim 1 , wherein the outer support is formed from flexible material.

7. The apparatus according to claim 6 , wherein the outer support is movable between a first position configured to receive the inner support and a second position configured to secure the inner support.

8. The apparatus according to claim 7 , wherein the outer support defines a bore having a circular-shaped cross section when the outer support is in the second position.

9. The apparatus according to claim 7 , wherein the outer support defines a bore having an elliptical-shaped cross section when the outer support is in the second position.

10. The apparatus according to claim 9 , wherein the at least one tooth of the outer support is located on a long side of the elliptical-shaped bore.

11. The apparatus according to claim 9 , wherein a force applied to a long axis of the outer support increases a distance between opposing teeth of the at least one tooth to release the inner support.

12. An apparatus for supporting an intraosseous device disposed at a target site in a patient, the apparatus comprising:

an inner support including a bore extending therethrough, the bore configured to receive a portion of the intraosseous device; and

an outer support including an adjustable inner diameter, the outer support configured to receive a portion of the inner support;

wherein an outer surface of the inner support includes a first engagement portion, an inner surface of the outer support includes a second engagement portion, and the first and second engagement portions are configured to engage each other to secure the inner support in place against longitudinal and rotational displacement relative to the outer support;

wherein a reduction of the inner diameter of the outer support secures the inner support in place against the longitudinal and/or rotational displacement;

wherein the outer support is formed from flexible material;

wherein the outer support is movable between a first position configured to receive the inner support and a second position configured to secure the inner support; and

wherein the outer support defines a bore having an elliptical-shaped cross section when the outer support is in the second position.

13. The apparatus according to claim 12 , wherein the outer support includes at least one tooth configured to engage at least one groove on the inner support in the absence of an external force.

14. The apparatus according to claim 13 , wherein the at least one tooth of the outer support is located on a long side of the elliptical-shaped bore.

15. The apparatus according to claim 13 , wherein a force applied to a long axis of the outer support increases a distance between opposing teeth of the at least one tooth to release the inner support.
