Abstract
A device for monitoring a constituent of body fluid continuously or repeatedly over a time period includes a body fluid sampling system and an optical sensor arrangement. The sampling system has a pumping arrangement which pumps body fluid from a cannula to a fluid sink. The optical sensor determines a concentration of at least one constituent of the body fluid. The pumping arrangement preferably ejects drops of body fluid from a fine nozzle. According to certain embodiments, optical sensor arrangements ensure that the optical paths do not pass through surfaces wetted by the fluid to be examined.
