Patent ID: 7828787

Claim:
A connector for packages containing medical fluids, comprising a tubular connection part for receiving a spike for the extraction of the fluid, the connection part comprising a lower section and an upper section, said parts being fixed in a snap-in manner, and a package-side lower opening and a connection-side upper opening; a break-off sealing part that seals the connection-side opening of the connection part; and a self-sealing membrane disposed in the connection part, which can be pierced by the spike for the extraction of the fluid, said self-sealing membrane comprising: an inner dish-shaped section having a top surface with a central recessed planar portion and an annular wall portion having a first inner face extending up at a first obtuse angle from the planar portion, which can be penetrated by a tubular extraction device; an inner circular section having a second inner face extending up from the first inner face at a second obtuse angle relative to the planar portion, wherein the second obtuse angle is greater than the first obtuse angle; and an outer circular section for the fixing of the membrane at the extraction point, said outer circular section having a substantially T-shape configuration clamped with elastic deformation of the membrane between the lower section and the upper section during use, wherein the inner circular section is connected to the stem of the T-shape of the outer circular section, wherein the inner circular section and the inner dish-shaped section together form a trough-shaped recess, and wherein the inner circular section of the membrane surrounds the spike in a sealed manner during penetration of the dish-shaped portion.
