Abstract
Devices and methods for use with syringes are disclosed. A plunger rod includes an outer housing having proximal and distal ends and a lumen between the ends, as well as an inner body axially slidable within the lumen between a first and second position. The inner body has a retention member extending therefrom. When the inner body is in the first position, the plunger rod has a first length, and, when the inner body is in the second position, the plunger rod has a second length greater than the first length. When the inner body is in the second position, the inner body is configured to be rotated relative to the outer housing until the retention member is received within the outer housing to preclude the inner body from moving in the axial direction.
