摘要：
Apparatus are disclosed for intraosseous fluid infusion or aspiration of bone marrow of a subject. Particular apparatus include a bone portal (bone-penetrating member) comprising axially-aligned distal and proximal sections. The proximal section extends in a distal direction from a proximate end of the bone portal and the distal section extends in the distal direction from the proximate section to a distal end of the bone portal. The bone portal also comprises a fluid-transport bore extending between a proximal opening in the proximal section and a distal opening in the distal section. At least a portion of the distal section has a cross-sectional area, perimeter, diameter and/or dimension greater than that of the proximal section.
