<p>A device (10, 110, 210) for the expression of liquids, such as for the maintenance treatment of vascular catheters. A syringe (16; 116a; 116b; 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 (14, 27, 258), to support structure (15, 215). At least one plunger (16; 116a, 116b; 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.</p> |
