ARTERY COMPRESSOR
The present invention relates to a compression arrangement ( 1 ) adapted to be arranged around a patient's forearm ( 9 ) to provide pressure to an artery puncture site ( 10 ). The compression arrangement ( 1 ) comprises, a ventral part ( 3 ), adapted to be arranged at the ventral side ( 12 ) of the forearm ( 9 ), a dorsal part ( 4 ), adapted to be arranged at the dorsal side ( 18 ) of the forearm ( 9 ), an attachment band ( 2 ), and a compression element ( 5 ) in the shape of an inflatable bladder, adapted to provide pressure to the artery puncture site ( 10 ) when the compression element ( 5 ) is inflated. The ventral part ( 3 ) comprises a compression element part ( 6 ) where the compression element ( 5 ) is arranged, and the ventral part ( 3 ) is essentially rigid and has a predetermined shape adapted to the anatomy of the forearm ( 9 ). The dorsal part ( 4 ) is at least partly adapted to be supported against the forearm ( 9 ) by a supporting part ( 8 ), the ventral part ( 3 ) and the dorsal part ( 4 ) being interconnected by a flexible part ( 7 ), such that the ventral part ( 3 ), the flexible part ( 7 ) and the dorsal part ( 4 ) generally form a U-shape being elastic and form stable, and wherein the attachment band ( 2 ) is adapted to adjust the ventral and dorsal parts ( 3, 4 ) in relation to each other.
