Abstract

The invention is directed to a wrist blood pressure monitoring device comprising a pressure sensor for detecting a pressure signal, an applicator unit for applying the pressure sensor against the wrist area of a subject's lower arm, an evaluating unit for evaluating the pressure signal, and an inclination detecting device for detecting the inclination of the blood pressure monitoring device and for delivering an electrical inclination signal corresponding to the inclination. According to the invention, the inclination detecting device comprises at least one movable, in particular pendulum-type positioning element and an inclination sensing device cooperating with the positioning element and including at least one sensing element movable with the positioning element and formed in particular by an optically reflecting, wedge-shaped arc section of the positioning element, and at least one further sensing element having in particular a reflected light barrier. The sensing elements are configured such that the electrical inclination signal is derivable from the relative position of the relatively movable sensing elements.
