Abstract:
1. An apparatus for controlling the depth of penetration of an intraosseous device into a sternal bone and associated bone marrow comprising: an outer penetrator having a first end and a second end; the second end of the outer penetrator operable to penetrate the sternal bone and associated bone marrow; a hub having a first end and a second end; a flange disposed at the second end of the hub, the flange extending radially outward from the hub and configured to be supported by a skin surface of a patient to stabilize the intraosseous device; the first end of the outer penetrator disposed in the hub; the second end of the outer penetrator extending from the flange; a collar having an elongated and hollow configuration compatible with engaging the outside diameter of the outer penetrator; the collar extending from the flange and disposed around a portion of the outer penetrator; the collar having a first end disposed toward the hub and a second end extending at a selected distance from the flange; and where the distance between the second end of the collar and the second end of the outer penetrator is non-adjustably fixed to control the depth of penetration of the intraosseous device into the sternal bone and associated bone marrow.
