Over-wrap bag enclosure for sterile connectors
View Patent ↗A hose barb connector or sanitary adapter connector can be attached to various types of containers intended for use in sterile operations, such as in a biotechnology and pharmaceutical fluid processing container system. An over-wrap bag such as a poly-bag (ZIP-LOC® or other type) attached by heat welding to a flange formed near the middle of the connector. The over-wrap bag maintains the sterility of the enclosed end of the connector. The other end of the connector is typically attached to a piece of tubing or conduit in communication with another larger bag, which has been rendered sterile collectively with the connector. Sterile fluids pumped into the bag, either though the connector itself, or through some other opening in the larger bag, will not be contaminated. In another embodiment, where the connector is not attached to another sterile fluid containing bag and it is desired to maintain the entire connector sterile, both ends of the connector (including the attached over-wrap bag) are enclosed by another poly-bag.
1. A connector assembly for containers used in sterile operations comprising: a connector having two ends and a flange formed thereon at a location which is intermediate said two ends; and an over-wrap bag enclosing one of said ends, said over-wrap bag being attached to said flange for maintaining sterility of said enclosed end; the connector assembly further comprising a second bag for enclosing said connector and said over-wrap bag for maintaining the sterility of said both ends of said connector assembly.
2. The connector assembly of claim 1 wherein said flange is curved.
3. The connector assembly of claim 1 wherein said flange is flat.
4. The connector assembly of claim 1 wherein the end of said connector which is not enclosed is attached to a large fluid-processing bag.
5. The connector assembly of claim 4 , further including another bag enclosing said large fluid-processing bag, said connector and said over-wrap bag.
6. A sterile connector assembly comprising: a connector having two ends; a flange formed on said connector intermediate said two ends; a sealing bag attached to said flange enclosing one end of said connector; and a second bag enclosing the said connector and said sealing bag for double sealing said end of said connector enclosed by said sealing bag, whereby said second bag is open in a sterile field so that the exposed end of the connector may be attached to sterile tubing said other end of said connector remaining sealed in said sealing bag to maintain its sterility.
7. The sterile connector assembly of claim 1 wherein said over-wrap bag is a zipper-locking bag.
8. The sterile connector assembly of claim 7 wherein said over-wrap bag is heat sealed adjacent said zipper lock to prevent said zipper lock from opening unless said heat seal is cut away.
9. The sterile connector assembly of claim 6 wherein said flange is curved.
10. The sterile connector assembly of claim 6 wherein said flange is flat.
11. The sterile connector assembly of claim 6 wherein said sealing bag is attached to said flange by a heat seal.
12. The sterile connector assembly of claim 6 wherein said connector is a hose barb connector.
