1. An intraosseous access system comprising:
a needle that defines a lumen and a longitudinal axis of rotation about which the needle is configured to be rotated to cut into a bone of a patient, the needle comprising:
a proximal end configured to remain at an exterior of the patient during use; and
a distal end configured for insertion through the skin of the patient into contact with the bone of the patient, the distal end comprising a distal tip positioned:
at a distalmost point of the intraosseous access system; and
on the longitudinal axis of rotation of the needle;
an obturator sized to be received within the lumen of the needle and configured to inhibit material from entering the needle as the system is inserted into said bone; and
a safety shield coupled to the obturator,
wherein:
a proximal end of the obturator is connected to an obturator hub and the proximal end of the needle is connected to a needle hub;
the obturator hub and the needle hub are configured to directly connect to one another;
the safety shield is coupled to the needle hub when the obturator hub and needle hub are connected to one another; and
the safety shield is configured to remain coupled with the needle hub and permit the obturator to translate proximally relative to the safety shield when the obturator hub is initially removed from and moved proximally relative to the needle hub.
