1. An intraosseous device, comprising:
a chamber portion comprising:
a distal end having a first surface with a first aperture configured to contact a patient body;
a proximal end having a distal facing surface; and
a sidewall extending between the first surface and the proximal end to define an internal chamber;
a tensile puller extending through the chamber portion including through the proximal end, the tensile puller comprising a continuous member extending from a proximal end to a distal end, and configured to rotate independently of the chamber portion;
a laterally extending handle attached to the proximal end of the tensile puller; and
a detachable actuating end arranged on the distal end of the tensile puller, the detachable actuating end configured to selectively engage a connector and having a proximal facing surface configured to engage the distal facing surface at the proximal end of the chamber portion when the tensile puller is retracted, wherein the detachable actuating end is configured to transition between a deployed position in which the actuating end extends out of the chamber portion through the first aperture, and a retracted position in which the actuating end is fully enclosed within the chamber portion, and wherein the transition between the deployed position and the retracted position is effected by a guided axial movement of the tensile puller within the chamber portion, and wherein a needle connected to the connector is fully withdrawn within the internal chamber in the retracted position.
