The present invention relates to a femoral compression system () for applying compression against a puncture site of a vessel in a patient, and a method for applying compression with a femoral compression system. The compression system () comprises an inflatable compression element () adapted to apply a pressure against the puncture site, a tightening unit () adapted to extend around a part of, or the whole of, the patients body to fixate and to tighten the compression element () against the puncture site, a pump () adapted to inflate the compression element (), a valve () adapted to deflate the compression element (), a pressure transducer () adapted to sense the pressure within the compression element (). The system further comprises a blood pressure pulse detector () adapted to sense the patient's blood pressure pulse and to generate a pulse signal in dependence thereto that is applied to a control unit () that is connected to the pump (), valve () and pressure transducer (), wherein the control unit () is adapted to control the pressure within the compression element () in dependence of the pulse signal, by applying control signals to said pump () and valve ().

Femoral compression system

A femoral compression device () for compressing a femoral artery () of a patient, having a base plate () provided with two opposing extensions, each of the two opposing extensions having a member for affixing a belt (), which is adapted to be arranged around a patient's body, an inflatable air cushion (), provided with a back plate (), for compressive bearing against a puncture site, and a pump () connected to the inflatable air cushion for inflation of the air cushion. The femoral compression device further comprises a spacer () having a height and being adapted to be mounted between the inflatable air cushion and the base plate.

Femoral compression device

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.
