Abstract

Fluid communication devices and supporting structures may be provided for use with intraosseous devices. Apparatus and methods may also be provided to communicate fluids with an intraosseous device.

First claim

What is claimed is:

1. An apparatus for supporting an intraosseous device having a hub portion and a cannula portion disposed at a target site in a patient, the apparatus comprising:
an inner collar including a first end and a second end, the inner collar further including a bore extending therethrough from the first end of the inner collar to the second end of the inner collar, the bore configured to receive the hub portion of the intraosseous device;
an outer collar configured to receive a portion of the inner collar, the inner collar operable to move relative to the outer collar, and
the outer collar operable to extend downward beyond the second end of the inner collar to provide stabilization against a patient's skin at the target site,
where a first end of the intraosseous device protrudes beyond the first end of the inner collar when the bore of the inner collar receives the hub portion of the intraosseous device to permit a connection of the first end of the intraosseous device to a connector when the cannula portion of the intraosseous device is inserted into the target site in the patient.

2. The apparatus according to claim 1 , wherein the inner collar and the outer collar are configured to fix a longitudinal position of the inner collar in relation to the outer collar.

3. The apparatus according to claim 1 , wherein the inner collar further comprises a pawl configured to move between a first position and a second position.

4. The apparatus according to claim 3 , wherein the first position is a retracted position, and the second position is a radially expanded position.

5. The apparatus according to claim 3 , wherein the pawl is configured to flex outward in relation to the inner collar.

6. The apparatus according to claim 5 , wherein the outer collar further comprises a plurality of grooves.

7. The apparatus according to claim 6 , wherein the pawl of the inner collar is configured to extend into the plurality grooves of the outer collar.

8. The apparatus according to claim 5 , wherein the pawl is configured to extend outward and operate as a friction lock with the outer collar.

9. The apparatus according to claim 8 , wherein the outer collar further comprises a rough surface, the pawl and the rough surface being operable to form a lock against longitudinal movement between the inner collar and the outer collar.

10. The apparatus according to claim 1 , wherein the connector further comprises a luer lock cap configured to securely mate with the first end of the intraosseous device when the hub portion of the intraosseous is received within the bore of the inner collar.

11. The apparatus according to claim 10 , wherein the luer lock cap is operable to push the inner collar in place in relation to the intraosseous device when mating the luer lock cap to the intraosseous device.

12. The apparatus according to claim 1 , wherein the inner collar is configured to mate with an exterior feature of the intraosseous device.

13. The apparatus according to claim 1 , wherein the outer collar includes a bottom face including an adhesive configured to adhere the outer collar to the skin of the patient.

14. An apparatus for supporting an intraosseous device disposed at a target site in a patient, the apparatus comprising:
a generally hollow cylindrical inner collar having a first end and a second end, the inner collar further having a configuration and interior dimensions compatible with exterior portions of the intraosseous device and configured to allow a first end of the intraosseous device to protrude therefrom; and
an outer collar having an opening formed therein, the opening having a configuration and interior dimensions compatible with exterior portions of the inner collar;
a proximal end of the outer collar operable to be disposed adjacent to an insertion site, and a distal end of the outer collar operable to extend from the insertion site; and
the opening of the outer collar operable to interact with the inner collar to releasably fix the position of the inner collar relative to the outer collar,
where the first end of the inner collar is configured to permit a connection of the first end of the intraosseous device to a connector when a second end of the intraosseous device is inserted into the target site in the patient.

15. The apparatus according to claim 14 , wherein the inner collar comprises at least one pawl operable to flex radially outward from the inner collar when the intraosseous device is disposed therein.

16. The apparatus according to claim 15 , wherein the opening of the outer collar is operable to interact with the at least one pawl to releasably fix a position of the inner collar relative to the outer collar.

17. The apparatus according to claim 16 , wherein the outer collar further comprises an adhesive layer operable to releasably engage the outer collar to a patient proximate the insertion site.
