摘要： An access port comprises a housing with a first opening formed therein and a septum mounted within the housing sealing the first opening, the septum including an outer surface covering the first opening and self-sealing after penetration by a needle and an attachment portion for securing the septum to the housing, the attachment portion including a chamfer which, when the septum is mounted within the housing is subject to a force oriented substantially perpendicularly with respect to a plane of the outer surface, the chamfered portion redirecting a portion of the force to compress the outer surface. A septum for an access port comprises an attachment portion adapted to abut a septum seat of the access port and an operative surface adapted to permit penetration by a needle and resealing itself after removal of the needle in combination with a chamfered portion providing a transition between the attachment portion and the operative surface, the chamfered portion re-directing a component of a force applied to the chamfered portion to compress the operative surface.
摘要翻译：入口端口包括壳体，其中形成有第一开口，并且安装在所述壳体内的隔膜密封所述第一开口，所述隔膜包括覆盖所述第一开口的外表面，并且在被针穿入之后自身密封，以及用于固定所述第一开口的附接部分所述安装部分包括倒角，所述倒角当所述隔膜安装在所述壳体内时受到基本垂直于所述外表面的平面定向的力，所述倒角部分将所述力的一部分重新定向以压缩外表面。用于进入端口的隔膜包括适于邻接进入口的隔膜座的附接部分和适于允许针穿透的操作表面，并且在移除针后与其自身之间重新密封，该倒角部分提供在安装部分和操作表面，倒角部分重新引导施加到倒角部分的力的分量以压缩操作表面。
