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 a 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 the 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 tubular sleeve and being axially displaceable relative to an outer surface of the inner tubular sleeve and a grip engaging an outer surface of the outer sleeve, the outer sleeve member operably connected to the driving member, and wherein the driving member includes a rod and a driving member hub engaging the outer sleeve member and having a throat portion receiving a proximal end of the rod therein;
a probe needle assembly engaged with the outer sleeve member and at least partially received within an interior of the inner tubular sleeve, and including at least one bone cortex-contacting probe needle, a motion inducer and an annular needle holder securing the at least one probe needle therein;
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 tubular 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 cortex of the target bone to the predetermined depth, to prevent any additional distal displacement of the bone portal;
whereby the proximal and distal springs provide a terminal feedback indicating mechanism configured to provide a tactile indication that the intraosseous catheter is either proximally or distally displaceable following application of the manual axial force in a corresponding direction when the bone portal penetrates the cortex of the target bone by less than the predetermined depth and that the intraosseous catheter is prevented from undergoing proximal or distal displacement after the bone portal has penetrated the cortex of the target bone to the predetermined depth despite application of the manual axial force.
