Abstract

The present disclosure relates to an apparatus for providing access to bone marrow and delivering a quantity of fluid to an intraosseous space. The apparatus may include a driver having a housing and a drive shaft, and a plunger operating and cartridge drive mechanism for releasably retaining a portion of a cartridge assembly having a plunger assembly. A plunger operating assembly may be disposed within a longitudinal bore of the plunger operating and cartridge drive mechanism. The plunger operating assembly may include a plunger barrel having a chamber configured to receive a portion of the plunger assembly of the cartridge assembly. The apparatus may also include a drive housing for transmitting rotational forces from the drive shaft to the cartridge assembly.

First claim

What is claimed is:

1. An apparatus operable to provide access to bone marrow,
the apparatus comprising:
a driver including a housing and a drive shaft, the housing having a first end and a second end, and the drive shaft extending from the first end of the housing;
a plunger operating and cartridge drive mechanism configured to releasably retain a portion of a cartridge assembly having a plunger assembly;
a plunger operating assembly disposed within a longitudinal bore of the plunger operating and cartridge drive mechanism, the plunger operating assembly including a plunger barrel having a chamber configured to receive a portion of the plunger assembly of the cartridge assembly; and
a drive housing having a first end, a second end, and a generally hollow cylindrical configuration extending from the first end toward the second end, wherein the drive housing is operable to transmit rotational forces from the drive shaft to the cartridge assembly releasably engaged with the plunger operating and cartridge drive mechanism.

2. The apparatus according to claim 1 , wherein the plunger operating and cartridge drive mechanism is releasably engageable with the driver.

3. The apparatus according to claim 1 , wherein the plunger operating and cartridge drive mechanism is operable to assume an uncocked and unloaded position, a cocked and unloaded position, a cocked and loaded position, and a discharge position.

4. The apparatus according to claim 3 , wherein the plunger operating and cartridge drive mechanism is operable to assume the uncocked and unloaded position while engaging the drive shaft of the driver.

5. The apparatus according to claim 1 , wherein the plunger operating and cartridge drive mechanism further comprises a retractable sleeve configured to receive the cartridge assembly and a bone penetrating needle.

6. The apparatus according to claim 5 , wherein the plunger operating and cartridge drive mechanism includes a first spring.

7. The apparatus according to claim 6 , wherein the retractable sleeve is operable to move longitudinally from a first, extended position, to a second, retracted position, to release the plunger operating assembly from a cocked position and allow the first spring to force the plunger assembly of the cartridge assembly to move from a first position to a second position.

8. The apparatus according to claim 1 , further comprising a release mechanism operable to disengage the cartridge assembly from the plunger operating and cartridge drive mechanism.

9. The apparatus according to claim 1 , wherein the plunger operating and cartridge drive mechanism further includes a second spring.

10. The apparatus according to claim 9 , further comprising a retractable sleeve slidably disposed within the longitudinal bore and operable to extend from the first end of the drive housing.

11. The apparatus according to claim 1 , wherein the second end of the drive housing includes an opening configured to receive the drive shaft.

12. The apparatus according to claim 1 , wherein the driver is a powered driver.

13. The apparatus according to claim 1 , wherein the driver further includes a handle extending from the second end of the housing, the handle including a trigger operable to activate the driver.

14. An apparatus for delivering fluid to an intraosseous space, the apparatus comprising:
a plunger operating and cartridge drive mechanism configured to releasably engage a drive shaft of a driver and a portion of a cartridge assembly having a plunger assembly;
a plunger operating assembly disposed within a longitudinal bore of the plunger operating and cartridge drive mechanism, the plunger operating assembly including a plunger barrel having a chamber configured to receive a portion of the plunger assembly of the cartridge assembly; and
a drive housing having a first end, a second end, and a generally hollow configuration extending from the first end toward the second end, the drive housing operable to transmit rotational forces from the drive shaft to the cartridge assembly engaged with the plunger operating and cartridge drive mechanism.

15. The apparatus according to claim 14 , further comprising a release mechanism operable to disengage the cartridge assembly from the plunger operating and cartridge drive mechanism.

16. The apparatus according to claim 15 , wherein the release mechanism includes a collet latch assembly configured to releasably engage a drive connector of the cartridge assembly proximate the first end of the drive housing.

17. The apparatus according to claim 16 , wherein the collet latch assembly includes a plurality of collet fingers with respective collet heads disposed on an end of each collet finger.

18. The apparatus according to claim 14 , wherein the plunger operating and cartridge drive mechanism further comprises a retractable sleeve configured to receive the cartridge assembly and a bone penetrating needle, the retractable sleeve slidably disposed within the longitudinal bore and operable to extend from the first end of the drive housing.
