1. A manual intraosseous device for introducing a bone portal to a predetermined depth relative to a surface of a target bone, comprising:
an intraosseous needle assembly including an intraosseous catheter configured to facilitate transfusion of fluids and aspiration of bone marrow and having a bone portal adapted to penetrate into subcutaneous tissue adjacent the target bone and the cortex of the target bone and a flexible tube configured to convey liquids to and from the bone marrow of the target bone, and a driving member releasably attached to the intraosseous catheter and by which a manual axial force is transmittable to the intraosseous catheter to initiate axial penetration into the subcutaneous tissue and cortex of the target bone;
an inner tubular sleeve arranged concentric to the intraosseous catheter;
an outer sleeve member including an outer sleeve arranged concentric to the inner sleeve and being axially displaceable relative to an outer surface of the inner sleeve and the outer sleeve member operably connected to the driving member, and wherein the driving member engages the outer sleeve member;
a probe needle assembly engaged with the outer sleeve member and at least partially received within an interior of the inner sleeve, and including at least one bone cortex-contacting probe needle;
a proximal spring positioned within the outer sleeve member, operably connected to the probe needle assembly, and configured to limit the depth that the bone portal penetrates the target bone; and a distal spring positioned within the inner sleeve, operably connected to the probe needle assembly, and configured to move the outer sleeve member to a starting position if the bone portal penetrates the target bone cortex to the predetermined depth, to prevent any additional distal displacement of the bone portal; and
a stabilizer including a base configured to detachably couple with a distal end of the inner sleeve and having at least one notch sized and shaped to receive at least a portion of the flexible tube therein.
