ABSTRACT:
A device (2) used to transfer the liquid contents (156) of a glass ampule (8) to a vial (10) includes a telescoping ampule body (12, 14) defining a collapsible, substantially air-tight region (22) within which the ampule is housed, which collapses when one part (12) is threaded onto the other part (14). This collapse increases the pressure within the collapsible region housing the ampule. The ampule is broken within the region, such as at the end of the collapsing of the telescoping members by snapping off the tip (64) of the ampule and breaking the base (48, 53) of the ampule. When used with a vial, a vial (10) is mounted to the ampule body via a vial body (80, 92). A vial spike (120) passes through the vial septum (128). The ampule body and the vial body defines a flow path (74, 100) between the vial spike and the ampule region. Once the flow path is open, the liquid from the ampule within the region flows along the flow path and into the vial because of the pressure created within the region.
