ABSTRACT:
A device for transferring and withdrawing liquids or liquid media from bottles, pouches or similar containers for medical purposes. The device includes a first rotationally-symmetric body including a threaded cam, a first spike with a tip, a first main duct extending to the tip, and a first auxiliary duct extending to the tip. The first auxiliary duct narrows to a capillary-like opening adjacent to the tip. A second rotationally-symmetric body is provided which includes a second spike with a second main duct and a second auxiliary duct. The first body is centrically plugged into the second body wherein the first spike is diametrically disposed with respect to the second spike. The first and second main ducts form a substantially linear, axially extending flow path through the device. The first and second bodies include a recess formed between the first auxiliary duct and the second auxiliary duct. A separate filter housing is connected to the threaded cam of the first body following the removal of the second body. A sealing surface on the filter housing is sealed against the first body with the filter of the filter housing disposed transverse to the axially extending flow path.
