Intraosseous access device and locator assembly

An apparatus for accessing an intraosseous space within a bone of a patient, the apparatus comprising:

• a penetrator assembly having a sharp penetrating end configured to penetrate the bone and associated bone marrow;
• a manual driver coupled to the penetrator assembly, the manual driver including a handle operable to manually drive the penetrator assembly into the bone and associated bone marrow;
• and
• a protective shield having a distal end and a proximal end, the protective shield slidably coupled to the handle and defining a longitudinal hollow passageway extending between the distal end and the proximal end;
• where the protective shield is operable to move between an extended position in which the sharp penetrating end of the penetrator assembly is disposed within the longitudinal hollow passageway of the protective shield to provide sharps protection, and a retracted position in which the sharp penetrating end of the penetrator assembly is disposed outside the longitudinal hollow passageway of the protective shield to permit penetration of the penetrator assembly into the intraosseous space;
• wherein the penetrator assembly further comprises an outer penetrator defining a longitudinal hollow bore, and an inner penetrator slidably receivable within the hollow bore of the outer penetrator.
