A venous access port assembly (10) having a housing base (28) with a discharge port (16), a septum (14) and a cap (48). An interior reservoir (22) is defined by a well (30) in the housing base and a bottom (62) of the septum, and a passageway (20) extends from the reservoir through the discharge port (16). The cap (48) is secured to an upper portion of the housing base and securely retains the septum in the assembly (10), compressing an annular flange (60) of the septum against a septum seat (52) of the housing base. The cap (48) is mechanically secured to the housing base (28) as well as being bonded thereto. A method is disclosed for mechanically securing the cap (48) to the housing base (28), in a manner compressing the flange (60) of the septum (14) and sealing the reservoir (22).

La présente invention concerne un ensemble d'orifice d'accès veineux (10) comportant un socle de boîtier (28) avec un orifice d'évacuation (16), un septum (14) et un capuchon (48). Un réservoir interne (22) est défini par un puits (30) dans le socle de boîtier et un fond (62) du septum, et un passage (20) s'étend depuis le réservoir à travers l'orifice d'évacuation (16). Le capuchon (48) est solidaire d'une partie supérieure du socle de boîtier et retient solidement le septum dans l'ensemble (10), comprimant une bride annulaire (60) du septum contre un siège de septum (52) du socle de boîtier. Le capuchon (48) est mécaniquement solidaire du socle de boîtier (28) auquel il est également scellé. L'invention concerne également un procédé de solidarisation mécanique du capuchon (48) au socle de boîtier (28), de manière à assurer la compression de la bride (60) du septum (14) et l'étanchéité du réservoir (22).
