A manual intraosseous (IO) device for introducing a bone portal to a predetermined depth relative to a surface of a target bone, and methods for using same. The device is manually actuated and configured to limit the depth of penetration of a bone portal into a bone cortex independently of an applied driving force and independently of subcutaneous tissue thickness surrounding the bone cortex, while providing terminal feedback that the bone portal has been penetrated to the predetermined depth. The device has transfusion facilitating components that remain fixed at the penetration site following penetration of the bone portal to the predetermined depth and releasable components that are separated from the transfusion facilitating components prior to a transfusion operation. The device may also include a stabilizer, or base, that allows a health practitioner to easily locate the insertion site and allows low profile fixation of the IO transfusion component (IO catheter).
