1. An intraosseous access device, comprising:
a trocar needle coupled to a device body, the device body configured to enable manual insertion of a distal tip of the trocar needle through a skin surface of a patient to an external surface of a bone of the patient; and
an intraosseous catheter removably disposed on the trocar needle, the intraosseous catheter comprising:
a catheter hub having a lumen extending therethrough;
a cannula disposed within the lumen and slidable with respect to the catheter hub to enable adjustment of a longitudinal length of the intraosseous catheter, wherein the cannula includes a first cannula portion and a second cannula portion that are telescopically mated to one another with a first O-ring interposed therebetween as to enable the first cannula portion and the second cannula portion to slide relative to one another, wherein the cannula is slidable with respect to the lumen of the catheter hub via a second O-ring interposed between the first cannula portion and the lumen of the catheter hub so as to enable the first cannula portion to slide relative to the catheter hub; and
an advancement mechanism configured to advance the trocar needle and the intraosseous catheter into an internal portion of the bone after the distal tip of the trocar needle and the intraosseous catheter have been inserted through the skin surface of the patient to the external surface of the bone of the patient.
