TRANSFER DEVICE FOR THE INTERCONNECTION OF SINGLE-USE SYNTHETIC BAGS AND/OR SYSTEMS FOR THERAPEUTIC OR OTHER PURPOSES

摘要

A transfer device for the interconnection of multi-part, single-use, synthetic bags (9, 10) and/or systems having independent compartments for therapeutic and other purposes includes a transfer tube (4) extending through the wall (11) of the synthetic bag which is sealed by a closing diaphragm (2) in the transfer tube (4). A piercing tube (1) is arranged in the interior of the synthetic bag and extends into the transfer tube (4). An internal flange (5) is formed on the wall of the transfer tube (4) at its end adjacent the interior of the synthetic bag (9). A groove (3) on the stem of the piercing tube (1) receives the internal flange (5) in the closed position of the bag (9). The piercing tube (1) terminates in a plate (6) manually engageable from the outside to push the tip of the piercing tube (1) through the diaphragm (2), whereby to allow the contents of the bag (9) to be discharged via the tubes (1) and (4).
