  • Publication number: 20030013976
    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.

  • Publication number: 20020156382
    Abstract: The invention is directed to a blood pressure monitoring device comprising a central parts mounting module and to a method of manufacturing this parts mounting module. According to the invention fluid channels are produced by gas injection into the interior of the parts mounting module, the walls bounding the fluid channels being completely formed by the material of the parts mounting module. The injection of gas continues for as long as a core of the parts mounting module is still in the liquid phase in the area of the fluid channel, whilst an outer area surrounding the core has already solidified, so that the pressure fluid expels the liquid core area, producing a tubular fluid channel.
