Abstract
The present invention relates to a sterile closure device that is particularly suited for flexible containers, or pouches, that contain medical fluids. The sterile closure device provides a port for a conventional spike set to puncture in order to attach a patient feeding line. The sterile closure device features at least two protection mechanisms that enhance sterility. Between the two protection mechanisms is a sterile chamber that minimizes leakage of medical fluid from the flexible container when the protection mechanisms are breached by a the spike set. The sterile closure device also features finger support to facilitate the user in grasping and puncturing the sterile closure device.

A closure device for a flexible container containing a medical fluid comprising:
- a boat-shaped base section having a top wall, a bottom wall, said base section adapted to fit said flexible container;
- a mid-section connected to said top wall,
- a support connected to said mid-section and adapted for a user to grip said closure device wherein said mid-section includes at least one spacer disposed between said top wall of said base section and said support;
- a cylindrical member extending through said base section, said mid-section and said support, said cylindrical member having a first opening in said base section and a second opening in said support, said cylindrical member adapted to allow said medical fluid to flow therethough and exit said flexible container;
- a first seal blocking said cylindrical member and capable of being breached;
- and
- a second seal covering said second opening and capable of being defeated;
- wherein a portion of said cylindrical member between said first seal and said second seal defines a chamber.
A container for a medical fluid comprising:
- a pouch having a port and at least a single edge such that said edge defines a reservoir within said pouch that is adapted to contain a medical fluid;
- and a closure device adapted to fit said port and comprises
- a base section having a top wall and a bottom wall, said base section sealingly attached to said edge of said pouch at said port;
- a mid-section connected to said top wall;
- a support connected to said mid-section and adapted for a user to grip said closure device, wherein said support further comprises a raised surface;
- a cylindrical member extending through said base section, said mid-section and said support, said cylindrical member having a first opening in said base section and a second opening in said support, said cylindrical member adapted to allow said medical fluid to flow therethough and exit said port;
- a first seal blocking said cylindrical member and capable of being breached;
- and
- a second seal covering said second opening and capable of being defeated, wherein said second seal is a peelable foil;
- wherein a portion of said cylindrical member between said first seal and said second seal defines a chamber.
A closure device for a flexible container containing a medical fluid comprising:
- a boat-shaped base section having a top wall and a bottom wall, said base section adapted to fit said flexible container and having a first width;
- a mid-section connected to said top wall, said mid-section having a second width that is smaller than said first width,
- a support connected to said mid-section, said support comprising at least one wing angulated with respect to said top wall and adapted for a user to grip said closure device wherein said mid-section includes at least one spacer disposed between said top wall of said base sectyion and said support;
- a cylindrical member extending through said base section, said mid-section and said support, said cylindrical member having a first opening in said base section and a second opening in said support, said cylindrical member adapted to allow said medical fluid to flow therethough and exit said flexible container;
- a first seal blocking said cylindrical member and capable of being breached;
- and
- a second seal covering said second opening and capable of being defeated;
- wherein a portion of said cylindrical member between said first seal and said second seal defines a chamber.
