A device ( 10,110,210 ) for the expression of liquids, such as for the maintenance treatment of vascular catheters. A syringe ( 16;116 a ,116 b ;216 ) has a support structure ( 15,215 ) and includes at least two separate compartments ( 11,12;111,112;211,212 ) in which liquids for treating the lumen (L, 283 ) of a catheter (C, 280 ) with which the device is associated. The syringe further includes a closure plug ( 13,213 ) to be associated with the lumen being treated, which is coupled, by virtue of a releasable securement arrangement, to support structure ( 15,215 ). At least one plunger ( 16;116 a ,116 b ;216 ) is also included for infusing, in preset order, the different treatment liquids into the lumen to be treated, and the syringe further includes a duct ( 17,217 ) which is in fluid communication with the two compartments and is arranged through a through hole through the closure plug ( 13,213 ) in order to allow access of the treatment liquid to the interior of the lumen (L, 283 ) upon activation of the plunger. |
