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.

Claims

1. A device for administering liquids to a patient'"'"'s body, comprising an administering part (10, 50) through which liquid can flow, and an adhesive plaster (11) for fixing the administering part (10, 50), wherein the adhesive plaster (11) comprises a first coupling part (38) which releasably engages with a second coupling part (43, 63) provided on the administering part (10, 50), characterized in that one of the two coupling parts (38;

43, 63) is configured as a plug-in pin (38) and the other coupling part as a round insertion opening (43, 63) such that the administering part (10, 50) is rotatable relatively to the adhesive plaster (11) about an axis extending vertically to the plane of the adhesive plaster.

2. The device according to claim 1, characterized in that the two coupling parts (38;

43, 63) are configured as snap elements.

3. The device according to claim 2, characterized in that the plug-in pin (38) keeps the administering part (10, 50) at a distance to a surface (37) on which the adhesive plaster (11) is stuck.

4. The device according to claim 1, characterized in that the plug-in pin (38) keeps the administering part (10, 50) at a distance to a surface (37) on which the adhesive plaster (11) is stuck.

5. The device according to claim 1, characterized in that the plug-in pin (38) is provided on the adhesive plaster (11) and the insertion opening (43, 63) on the administering part (10, 50).

6. The device according to claim 1, characterized in that the adhesive plaster (11) comprises a non-adhesive flap (46).

7. The device according to claim 1, characterized in that the administering part (50) further comprises an oblong hole (64) for fastening the administering part (50) with a tape.

8. The device according to claim 1, characterized in that the surface (14) of the administering part (10) facing the adhesive plaster (11) is provided with knops (45).

9. The device according to claim 1, characterized in that the plug-in pin (38) comprises a spherical thickened head which allows the administering part (10, 50) to be tilted.
