Abstract
The invention relates to an automatic identification method for the cuff of a sphygmomanometer. When changing the pressure in a cuff (6 or 19) or in a space in flow communication therewith, the pressure change occurring in this space is monitored at two spaced-apart measuring points by means of one or a plurality of pressure-sensing means (12 and/or 9) and the pressure signals obtained from these two measuring points are compared to each other and, on the basis of the conducted comparison, the different cuff types are distinguished from each other as the measured pressure difference indicates a cuff type presently in use.
