Abstract: The invention relates to a sensor device for capturing data when carrying out first aid measures for reanimating a person affected by a cardiac arrest. The sensor device is exactly positioned on the chest of the patient by means of a positioning-aid apparatus (5) and affixed by means of a fastening means (2). The thorax compressions, i.e., the pressing-in depth and compression frequency, are detectable by means of a motion sensor. A data-transfer interface allows communication, e.g. wireless communication, with a mobile terminal.

Abstract: The invention relates to a device for assisting a first aider with a cardiopulmonary resuscitation of a person suffering cardiac arrest, comprising a transport housing (1), in which a sensor apparatus (4) and two adhesive electrodes (2), which are or can be connected to the sensor apparatus (4), can be stowed. The sensor apparatus (4) allows data to be acquired while the first-aid measures for resuscitation are performed. The sensor apparatus (4) comprises an adhesive (5) for attachment to the chest of the patient (3). The chest compressions, i.e. depth of compression and compression frequency, can be detected by means of a motion sensor. An interface for data transfer allows wireless communication with a mobile terminal (6). Furthermore, the sensor apparatus (4) contains a high-voltage store so that, after connection to the adhesive electrodes (2), a single defibrillation shock can be delivered.

Abstract: The invention relates to a system for assisting a helper (8) in the performance of chest compressions for the immediate resuscitation of a person (1) affected by a circulatory arrest, wherein the helper (8) may be an untrained novice helper, in particular. In order to identify the circulatory condition of the person (1) and impart assistive first measures, a position sensor (4) connected to a support of similar design to a sticking plaster (5) is arranged on the sternum (2) of the person (1) by means of adhesion at an appropriate position. The position sensor (4), which is in the form of an acceleration sensor, is additionally connected to a mobile terminal (6) wirelessly or by wire. This terminal (6) is in the form of a smartphone, the smartphone being equipped with an appropriate application program (7).
