Abstract

device for administering liquids comprises an administering part (10) and an adhesive plaster (11). The administering part (10) is connected with a cannula stud (30) and an administering line (14) and carries a liquid. For fastening the administering part (10) to the surface of a patient's skin or the surface of an object the adhesive plaster (11) is stuck on the surface. The adhesive plaster (11) is provided with a plug-in pin (38) which is adapted to be inserted into an insertion opening (43) of the filter (10). By placing the filter (10) onto the plug-in pin (38) the administering part (10) is detachably connected with the adhesive plaster (11). If the administering part (10) is a filter with transparent housing the filter membrane is well visible since the latter is not covered by adhesive strips when the filter is fastened to the patient's body.
