摘要： A cartridge assembly for delivering a quantity of medication to bone marrow of a bone comprising a fluid reservoir (132; 132a) having a first end and a second end; a hollow, bone penetrating needle (160) releasably engaged with the first end of the fluid reservoir (132; 132a), the needle (160) operable to penetrate into the bone and bone marrow; a plunger assembly (82) including a plunger shaft (142) and a piston (144) slidably disposed in the fluid reservoir (132; 132a); a drive connector (150) attached to the second end of the fluid reservoir (132; 132a) opposite from the bone penetrating needle (160); and a portion of the plunger shaft (140) extending from the second end of the fluid reservoir (132; 132a), where the needle (160) is operable to be disengaged from the fluid reservoir (132; 132a) when the needle (160) has penetrated into the bone and bone marrow.
