Abstract

La présente invention concerne un dispositif (10) de test sanguin qui comprend une extrémité proximale (12), une extrémité distale (14), une partie intermédiaire (20) située entre l'extrémité proximale (12) et l'extrémité distale (14), un système de compensation de pression destiné à réguler la pression dans la partie intermédiaire (20), et un capuchon (60) d'extrémité distale positionné au niveau de cette extrémité distale (14) comprenant une première ouverture (62) agencée de façon à recevoir une bande test (104). La partie intermédiaire (20) comprend une extrémité proximale (36) comprenant une ou plusieurs ouvertures (44), une extrémité distale (38) de cette partie intermédiaire (20) et, entre cette extrémité proximale (36) et cette extrémité distale (38) une chambre (40) centrale creuse entourée d'une paroi (42) extérieure.
