Abstract
A pressure measurement device for measuring pressure and/or for measuring elasticity of a vein, an organ or a compartment of a body in combination with an ultrasound measurement unit. A pressure sensor is configured as a thin film pressure sensor with the speciality that the intermediate space, between the films of the film pressure sensor, is filled with an ultrasound-transparent and electrolytically/electrically inactive liquid. The films of the film pressure sensor are fabricated from an ultrasound-transparent material.
