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.

Abstract: A process and a device for automatically detecting an abnormal respiratory ound permits a continuous and stress-free registration of abnormal respiratory sounds of a test person under normal life activities over a period of time. The respiratory sounds are detected, processed and evaluated in real time. From the detected frequency range, in the course of the evaluation consideration is given only to the previously determined characteristic frequencies at the position of which in the frequency spectrum of the respiratory sound of the test person an abnormal respiratory sound is to be recognized by a significant feature. The data detected at these frequency positions are compared with data which are individually determined for the test person for fulfillment of specific criteria for the occurrence of an abnormal respiratory sound, and the result of the comparison is made available as a signal.
