The invention is directed to a method and a device for determining the blood pressure, in which a pressure sensor is applied to an individual’s limb to detect the blood pressure prevailing in said limb. Parameters are at least partially combined to form at least one parameter class. The inner threads allow attaching of the outer section into the central section so that the pipe insert may vary the relative displacement between the free ends of the pipe insert to correspond to the spacing between the pipe ends. The present disclosure also includes associated devices applying the correction table and methods of generating the correction table. A system and a computer-readable storage medium are also described and claimed.
