Abstract
A femoral compression device () for compressive bearing against the femoral artery of a patient, comprising a base plate (), an inflatable air cushion (), and an electronic manometer () 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 () 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.
