Abstract

An apparatus for penetrating the bone marrow of a bone is provided. The apparatus includes a handle having a drive shaft, a connector having a first end operable to connect to a drive shaft and a second end operable to connect to a penetrator hub and a penetrator hub having a penetrator that accesses the bone marrow.

Claims

1. An apparatus for penetrating the bone marrow of a bone comprising:

a handle comprising a drive shaft;

a connector comprising a first end operable to connect to the drive shaft and a second end operable to attach to a penetrator hub; and

the penetrator hub comprising a penetrator operable to access the bone marrow.

2. The apparatus of claim 1, the handle selected from a group consisting of T-shaped, substantially round-shaped, substantially oval-shaped, grip-shaped and substantially ergonomic-shaped.

3. The apparatus of claim 1 wherein the drive shaft comprises a ratchet.

4. The apparatus of claim 1 wherein the connector is selected from a group consisting of a magnet, an O-ring mechanism and a ball and detent mechanism.

5. The apparatus of claim 1 wherein a second end of the connector comprises a threaded connection.

6. The apparatus of claim 1 wherein the hub comprises a threaded connection.

7. The apparatus of claim 1 wherein the penetrator comprises a hollow channel and a tip having one or more cutting surfaces.

8. The apparatus of claim 1 wherein the connector is releasably attached to the drive shaft.

9. The apparatus of claim 1 wherein the handle comprises at least one storage compartment.

10. The apparatus of claim 1 wherein the handle comprises at least one drive shaft.

11. The apparatus of claim 1 wherein the connector comprises a trocar.

12. An apparatus for penetrating bone marrow of a bone comprising:

a handle comprising at least one drive shaft;

a releasable connector comprising a first end operable to connect to a drive shaft and a second end comprising a threaded connection operable to attach to a penetrator hub; and

a penetrator hub comprising a penetrator and a threaded connection operable to access the bone marrow.

13. The apparatus of claim 12 wherein the connector is detachable from the hub.

14. A method of accessing bone marrow of a bone comprising:

inserting a penetrator, defined in part by an outer cannula and an inner trocar, into the bone and associated bone marrow by a handle rotating a drive shaft and an attached connector;

detaching the handle and connector from the hub; and

removing the trocar from the cannula to allow access to the bone marrow through the cannula.

15. An apparatus for penetrating bone marrow of a bone comprising:

a driver comprising a housing, a motor, a gear assembly, at least one drive shaft and a power source; and

at least one drive shaft operable to connect to an auxiliary device and further operable to provide rotational energy to the device.

16. The apparatus of claim 15 wherein the power source is selected from a group consisting of a battery pack, electricity, a spring, a gas cartridge and solar power.

17. The apparatus of claim 15 wherein the auxiliary device is selected from a group consisting of a ring cutter, a suction device, and a flashlight.

18. The apparatus of claim 15 wherein the at least one drive shaft is operable to attach to a connector having a first end and a second end operable to connect to a hub comprising a penetrator.

19. An apparatus for penetrating a bone and providing access to associated bone marrow comprising:

a handle having at least one drive shaft extending therefrom;

a connector having a first end operable for releasable attachment to the drive shaft and a second end operable for releasable attachment to a penetrator hub;

the penetrator hub defined in part by a flange having a first end and a second end;

the first end of the hub operable for releasable attachment with the second end of the connector;

a penetrator extending from the second end of the hub and the tip of the penetrator spaced longitudinally from the second end of the hub to accommodate penetration of the bone and associated bone marrow; and

the tip of the penetrator operable to penetrate the bone in response to rotary motion from the handle.

20. A method of accessing bone marrow of a bone comprising:

releasably attaching a connector with a handle operable to rotate the connector;

releasably attaching a penetrator with the connector;

rotating the handle to rotate the connector and the penetrator to insert the penetrator into the bone and associated bone marrow;

detaching the handle and the connector from the penetrator when one end of the penetrator is located at a desired position within the bone marrow; and

connecting a tubing with the penetrator to communicate fluid between the tubing and the bone marrow.

21. An container operable to enclose a penetrator assembly for penetrating the bone marrow comprising:

a substantially longitudinal receptacle comprising a substantially rounded first section operable to accommodate a penetrator assembly and a substantially rounded second section operable to accommodate an outer penetrator and inner trocar; and

a cap including a tab operable to be opened with digital pressure.

22. The container of claim 21 wherein the receptacle comprises a seal portion operable to attach to a the cap to prevent contamination of the penetrator assembly.

23. A penetrator assembly for penetrating a bone and providing access to associated bone marrow comprising:

an outer hollow penetrator attached to and extending from a hub;

the hub includes one or more indentations suitable for grasping; and

an inner trocar releassably engaged with the outer penetrator.

24. The apparatus of claim 23 wherein the outer hollow penetrator comprises a tip with at least one cutting edge operable to penetrate the bone.

25. The apparatus of claim 23 wherein the outer hollow penetrator comprises a tip with a cutting edge on each of four sides of the penetrator.

26. The apparatus of claim 23 wherein the inner trocar comprises a tip with a cutting surface on each of two sides of the trocar.

27. The apparatus of claim 23 wherein the penetrator assembly comprises a protective cover having at least one ridge operable to be grasped and removed by an operator.

28. An apparatus for penetrating bone marrow of a bone comprising:

a handle having a at least one drive extending therefrom;

a penetrator hub operable for releasable attachment with the driver; and

the penetrator hub having a penetrator operable to access the bone marrow.
