Abstract: The invention relates to a respiration bag (1) which has at least one fold (2, 11) extending annularly over the bag (1). The respiration bag (1) can be bent in along this fold (2, 11). In this way, at least one depression results which leads to a reduced volume of the respiration bag (1). A flip over of the respiration bag from the bent-in position is prevented by sealing lips (10, 12) or additional mechanical holders which are applied from the outside to the at least one fold (2, 11). The respiration bag (1) remains stable in the bent-in position with reduced volume up to an inner pressure of 45 to 50 millibar. In this way, a respiration bag (1) for respiration volumes of different sizes is available in dependence upon, for example, whether respiration is to take place with ambient air or oxygen-enriched air or is dependent upon whether an adult or a child is to be respirated.

Abstract: A personal emergency-reporting system for recognizing the site of an emergency with simultaneous warning of the nearest emergency physician/medical personnel. A portable patient data unit is provided which contains a satellite-supported global positioning system, which communicates with a patient data acquisition and evaluation unit via a computer and control unit, wherein the latter is connected to an emergency call transmitter. The transmitter sends patient data and the patient's position to an emergency call receiver in the case of an emergency. An automatic emergency-reporting system is provided by the present invention in order to make possible a rapid and specific rescue operation to a person whose health is acutely at risk.
