Abstract

Apparatus for delivering a quantity of fluid to bone marrow of a bone or providing access to remove fluids from a target site is provided. The apparatus may include a driver, a plunger operating and cartridge assembly mechanism, a cartridge assembly having a fluid reservoir and a bone penetrating needle.

Claims

1-31. -31. (canceled)

32. A cartridge assembly for delivering a quantity of medication to bone marrow of a bone comprising:

a fluid reservoir having a first end and a second end;

a hollow, bone penetrating needle engaged with the first end of the fluid reservoir;

a plunger assembly including a piston and a plunger shaft attached to the piston;

the piston slidably disposed in the fluid reservoir;

a portion of the plunger shaft extending from the second end of the fluid reservoir;

a drive connector attached to the second end of the fluid reservoir opposite from the bone penetrating needle; and

the drive connector operable to rotate the cartridge assembly in response to rotation of the drive connector by an associated drive housing.

33. The cartridge assembly of claim 32 further comprising the fluid reservoir formed at least in part by a material selected from the group consisting of glass composite, plastic, or a plastic composite.

34. The cartridge assembly of claim 32 further comprising the fluid reservoir filled with one or more fluids selected from the group consisting of medications for treatment of cardiac arrest, antibiotics, poison antidotes, nerve gas antidotes, radioprotectants to protect the body against radiation exposure, normal saline solutions, lactated Ringer'"'"'s solution, blood, plasma, albumin and other bio-compatible fluids.

35. The cartridge assembly of claim 32 comprising a detachable fluid reservoir.

36. The cartridge assembly of claim 35 further comprising a hub operable to releasably engage the hollow, bone penetrating needle with the first end of the detachable fluid reservoir.

37. The cartridge assembly of claim 36 wherein the hub further comprises:

a first end and a second end;

the second end of the hub having a threaded connection disposed adjacent thereto; and

the hollow, bone-penetrating needle attached to and extending from the first end of the hub.

38. The cartridge assembly of claim 37 further comprising:

a recess formed in the piston; and

the recess sized to receive the second end of the hub within the piston to allow disengagement of the first end of the fluid reservoir from the hub after the hollow, bone-penetrating needle has been inserted through portions of a bone and bone marrow proximate a target site.

39. The cartridge assembly of claim 37 further comprising a luer fitting formed on the second end of the hub.

40. The cartridge assembly of claim 32 wherein the hollow, bone penetrating needle further comprises:

a first end having a closed tip;

at least one cutting edge formed on the closed tip for use in penetrating the bone and bone marrow;

a second end operable to receive a quantity of fluid from a fluid reservoir;

a longitudinal bore extending from the second end to a location proximate the closed tip;

at least one side port located proximate the closed tip;

the at least one side port communicating with the longitudinal bore proximate the closed tip; and

the at least one side port disposed at an acute angle relative to the longitudinal bore to minimize obstruction of the at least one side port and the longitudinal bore by bony fragments during insertion of the bone penetrating needle into the bone and associated bone marrow.
