    Abstract: A pressure sensor wire assembly measures pressure inside a body of a patient. The assembly comprises a pressure sensor element for measuring pressure and to generate a pressure sensor signal representative of the pressure, and a pressure sensor wire having the pressure sensor element at its distal portion, and adapted to be inserted into the body in order to position the sensor element within the body. A sensor signal adapting circuitry is an integrated part of the assembly, wherein the pressure sensor signal is applied to the adapting circuitry which is adapted to automatically generate an output pressure signal, related to the sensor signal, in a standardized format such that the measured pressure is retrievable by an external physiology monitor. The assembly further comprises an external pressure sensor to measure the pressure outside the patient's body and to generate external pressure values in dependence thereto.

    Abstract: A femoral compression device (1) for compressive bearing against the femoral artery of a patient, comprising a base plate (2), an inflatable air cushion (4), and an electronic manometer (8) connected to the inflatable air cushion for measurement of the current pressure difference between the pressure prevailing inside the inflatable air cushion and the ambient air pressure. The femoral compression device can further comprise a mechanical device (11; 46) which prevents an air opening leading to the inflatable air cushion from being closed before the manometer is zeroed. In another embodiment, an electronic manometer is provided such that a current characteristic of an electric signal representing the current pressure difference can be compared with a corresponding characteristic which was obtained at zero pressure difference and which was stored in the electronic manometer, wherein the manometer cannot be zeroed as long as the current characteristic deviates more than a predetermined amount from the stored characteristic.
