1. A device for attaching a sensor to the surface of the skin so as to fix the sensor to the skin, the device comprising:
- a basic plaster having a supporting layer and an adhesive layer; and
a detection plaster having a supporting layer, a recess being provided in the supporting layer of the detection plaster, the supporting layer of the detection plaster being attachable to the adhesive layer of the basic plaster to provide a hollow space therebetween, the recess being a part of the hollow space, an adhesion strength between the supporting layer of said detection plaster and the adhesive layer of the basic plaster being less than an adhesion strength between the basic plaster and the skin and an adhesion strength between the detection plaster and the skin.

Abstract
The present invention relates to a device for attaching sensors to the surface of the skin comprising a basic plaster 3 and a detection plaster 4 which comprises a recess so that a hollow space 5 is provided between the basic plaster 3 and the detection plaster 4. The hollow space may contain a dye solution, solid matter, or odor marker which escapes during the unauthorized removal of the sensor by tearing open the hollow space 5.

12. A method for proving removal of a sensor from skin, the method comprising the steps of:
-
fixing the sensor to the skin, the sensor being fixed by an attachment device, the attachment device including a basic plaster having a supporting layer and an adhesive layer, and the attachment device further including a detection plaster having a supporting layer and an adhesive layer, a recess being provided in the supporting layer of the detection plaster;
adhering the basic plaster on the skin and adhering the detection plaster on the skin during the step of fixing;
attaching the supporting layer of the detection plaster to the adhesive layer of the basic plaster to form a hollow space therebetween, the recess being a part of the hollow space;
providing adhesion strength between the supporting layer of the detection plaster and the adhesive layer of the basic plaster to be less than adhesion strength between the basic plaster and the skin and less than adhesion strength between the detection plaster and the skin;
peeling the basic plaster from the skin while the detection plaster remains on the skin with its adhesive layer during the removal of the sensor; and
tearing open the hollow space during the step of peeling in order to prove removal of the sensor. - View Dependent Claims (13)
