An elongated access port (18) has a needle-impenetrable housing (40) that includes a base (44) with an upstanding encircling sidewall (70) and a cap (42) with a depending encircling skirt (46) for receiving the sidewall (70). An access aperture (130) encircled by a continuous rim (138) of elongated shape extending through the cap (42) may be elliptical, oval, polygonal, or parabolic-ended. A needle-penetrable septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) is installed in the access aperture (130) with the periphery (138, 188, 204) of the septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) in sealing engagement with the rim (128) of the access aperture (130). Prior to installation, periphery (138, 188, 204) is geometrically proportional to and larger than the access aperture (130). The relative sizes and shapes of the rim (128) and the periphery (138, 188, 204) produce substantially uniform hydrostatic pressure in regions of the installed septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) subjectable to needle penetration. Opposite faces (140, 142) of the septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) at the periphery (138, 188, 204) are urged together between the cap (42) and the top (120) of the sidewall (70) of the base (44).

L'invention porte: sur un point d'accès oblong (18) comprenant un boîtier oblong (40), non transperçable dont la base (44) est entourée d'une paroi latérale verticale (70), et dont le couvercle (42) est entouré d'une jupe (46) attenante s'emboîtant sur la paroi latérale (70); sur un orifice d'accès (130) entouré d'un bord continu large (138) s'étendant à travers le couvercle (42) et pouvant être elliptique, ovale, polygonal ou à extrémité parabolique; et sur un septum transperçable par une aiguille (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) se montant dans l'orifice d'accès (130) et dont la périphérie (138, 188, 204) est en contact étanche avec le bord (128) de l'orifice d'accès (130). Avant le montage, la périphérie (138, 188, 204) se trouve géométriquement proportionnelle à l'orifice d'accès (130), mais plus large. Les tailles relatives du bord (128) et de la périphérie (138, 188, 204) produisent une pression hydrostatique sensiblement uniforme dans la région du septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) transperçable dont les faces opposées (140, 142) au niveau de la périphérie (138, 188, 204) sont pressées entre le couvercle (42) et le sommet (120) de la paroi latérale (70) entourant la base (44).
