The present invention relates to devices and methods for uptaking and analyzing sweat from a skin of a user. In particular, it is proposed to provide a variability in the size of the sweat sensor inlets (), which can be used for improving the determination of sweat parameters like for example determining the number of active sweat glands The variability in the size of the inlets () with which the sweat sensor () uptakes the sweat from the user's skin () can be achieved by having either plurality of inlets wherein at least some of them have different opening sizes and to use the differently sized inlets based in different situations. Alternatively, one or more inlets may have openings with variable cross-sectional area, like e.g. an adjustable diameter of their opening, and also a combination of these two alternatives is of course possible. A processor of the sweat sensor may use the information from either all or only the most appropriate sized inlets to determine a sweat parameter. In another alternative, the processor may adapt the inlet to the adjustable inlet opening to the most appropriate size to then determine a sweat parameter of interest.

Sweat sensor

The invention provides a patient monitoring system for monitoring a patient in a bed. A video camera is used for capturing video images of the patient. Video analysis is used to determine and track the position of body parts of the patient including the hands. This analysis is enhanced by using sensors which detect interaction by the patient with pieces of equipment in the vicinity of the bed.

Patient monitoring system and method

The invention suggests a system for monitoring the exposure of a patient () to at least one environmental factor. The system particularly comprises a database () storing an environmental prescription for the patient, the environmental prescription specifying a maximum level of the environmental factor and a minimum duration for the level of the environmental factor to be smaller than the maximum level, and an evaluation module () configured to detect on the basis of a measurement signal and the stored environmental prescription a time interval in which a level of the environmental factor is below the maximum level and to compare the duration of the detected time interval with the minimum duration. On the basis of the result of this comparison, healthcare staff can plan activities in such a way that the patient is provided with a rest period substantially having the minimum duration.
