Femoral compression device
First Claim
1. A femoral compression device for compressive bearing against the femoral artery of a patient, comprising:
- a base plate;
an inflatable air cushion attached to the base plate;
a first extension extending from a first side of the base plate;
a second extension extending from a second side of the base plate, said second side being opposite to the first side;
a belt adapted to be attached to an end of the first extension and being adapted to extend around the patient'"'"'s body to be attached to an end of the second extension;
a pump connected to the inflatable air cushion for inflation of the inflatable air cushion;
a manometer connected to the inflatable air cushion for measurement of a current pressure difference between pressure prevailing inside the inflatable air cushion and ambient air pressure, wherein the manometer is an electronic manometer; and
a mechanical device comprising a closing portion, and a removable portion configured to prevent the manometer or circuits thereof from being electrically powered while preventing the closing portion from closing an air opening leading to the inflatable air cushion.

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.

15. A method of promoting healing of a blood vessel after completion of an interventional procedure which required access to a patient'"'"'s vascular system via a puncture in the blood vessel, comprising:
-
removing a removable portion of a mechanical device configured to prevent an electronic manometer or circuits thereof from being electrically powered and to prevent a closing portion of the mechanical device from closing an air opening leading to an inflatable air cushion before being removed; placing the inflatable air cushion in contact with the patient near the puncture; and monitoring air pressure inside the air cushion with the electronic manometer to determine a condition of the puncture. - View Dependent Claims (16, 17)
