Sterile openable access port and containers including the same

摘要

A connector for providing sterile access to a flexible container is provided that comprises a tubular member having a first portion and a second portion, each of the first portion and the second portion having an open end. The first portion and second portion are joined to each other by a frangible segment, with each of the first portion and the second portion having a gripable surface associated therewith that is configured to facilitate the application of torsional force to the tubular member at the frangible segment. Upon the application of a sufficient amount of torsional force, the frangible segment will break, permitting the first and second portions to be separated from each other.

主权项

1. A connector for providing sterile access to a flexible container for receipt of a medical fluid comprising:
a tubular member having a first portion and a second portion, each of the first portion and second portion having an open end; the first portion and the second portion joined to each other by a frangible segment; each of the first portion and the second portion having a generally planar gripable surface associated therewith comprising raised ribs configured to facilitate the application of torsional force to the tubular member at the frangible segment; the first portion having a seal on the end thereof and the second portion having a pierceable membrane and being configured to have the flexible container attached thereto, the gripable surface associated with the second portion being positioned thereon so as to be exterior to the flexible container; the second portion includes a radially-outwardly extending flange adjacent the frangible segment and a tubular extension configured to receive a spike extending beyond the flange and having an outer diameter smaller than the inside diameter of the first portion, the tubular extension extending past the frangible segment into the first portion, the flange having a diameter that is greater than the length of the tubular extension; and the tubular extension comprises an inside surface configured to receive and engage a spike to penetrate the pierceable membrane, the inside surface having a roughened surface finish for reducing friction between the inside surface and a spike received therein.
