Description
.32~8 PORT ASSEMBLY FOR A CONTAINER
BA~KGROUND OF THE INVENTI~N
The present invention relates qenerally to a port and closure assembly for a ContainQr. More specifically, the present invent~on relates to the port assembly that is used to access a container that houses a liquid.
Ports are utilized to access material packaged within a container. As used herein, the term "ports"
includes, without limitation, fitments, valves, and other means for accessing a container. In the medical industry, parenteral and peritoneal dialysis solutions are packaged in rlexible containers that are accessed via a port~ An example of such a flexible container is the VIAFLEX~ collapsible plastic container 601d by Baxter Healthcare Corporation of Deerfield, Illinois.
The port can function not only to provide means for accessing the solution contained within the container, but also can provide a ~ite for the injection of material into the solution container. For example, it may be desirable to inject a medicament into a dextrose or saline solution, and then administer the resultant product intravenously into a patient. Such an injection site, however, must be 80 constructed that it is resealing so that contamination of the resultant product is prevented and the resultant product does not leak out the injection port.
Typically, the port assembly comprises a tubular structure having an inner bore, that extends from a base that is secured to the container. Located within the bore, typically, is a needle pierceable wall that provides a barrier between the fluid contained within the container and the outside environment. Usually, pointed - 2 - ~ ~23~3~
means that pierce the pierceable wall, are used to gain accQss to the container and thereby the fluid housed therein. To guard against contamination at the port, closures are typically utilized for covering the opening of the port.
Although port assemblies having injection sites are known, these port assemblies have not been entirely satisfactory. Some of the problems of prior port assemblies relate to the manufacturing process and the failure of the injection site to be sufficiently secured withln the port of the port assembly.
There is therefore a need for an improved port assembly having an injection site.
SUMMARY OF T~E IYY~IIn~
The present invention provides an improved port assembly for a container. To this end, the port includes an alongated tube extending from an end of a base that is secured to a container.

DE~AILED DE~CR~IION_QF TH~ ~ S
The present invention provides an improved port assembly for a container. As previously stated, the port provides a means for accessing the container. To this end, the port can provide a means for ~n~ecting into the container a ~ubstance or withdrawing therefrom the contents of the container. The container can be any known in the art. However, the pre~ent invention is particularly directed to use with a container for housing solutions for use in the medical industry, these fluids should be maintained and extracted under sterile condition~.
Referring to Figur~ 1, the port assembly lQ of the present invention is illustrated. ~8 illustrated, the port assembly 10 includes an injection port 12, an administration port 14, and a base 16. Preferably, the base 16 of the port assembly 10 is ~ecured to a container 17, such as a flexible bag. In the embodlment of the invention illustrated, the base ~6 is not planar, but instead includes curved portions 19, to improve delivery of the product housed in the container to the ports.
The in~ection port 12 and administration port 14 extend from the base 16 and include openings 18, and 20, respectively, that allow the injection port and administration port to be in fluid communication with the contents of the container. Although, ~n the embodiment of the invention illustrated in Figure 1, the port assembly 10 includes an in~ection port 12 and an administration port 14, the port assembly 10 of the present invention can include more or less port members.
Preferably, the in~ection port 12 functions as a '~r"
..
1323~
means for in~ecting into the container 17, to which the port assembly 10 i8 secured, a substance, such as a drug, that is to be diluted with the contents of the container 17. Preferably, the administration port 14 functions to provide a means for accessing the contents of the container. To this end, the administration port 14 is 80 constructed and arranged that it can receive a spike portion of an administration site, that allows the contents of the container 17 to be, for example, intravenously administered to a patient.
Referring now to Figure 2, the in~ection port 12 is illustrated. The in~ection port 12 includes a tubular wall 22 that defines therein a tubular bore 24. Located within the tubular bore 24 is a pierceable membrane 26.
The pierceable membrane 26 divides the tubular bore 24 into an upper portion 28 and a lower portion 30.
Located within the upper portion 28 of the tubular bore 24 is a resealing in~ection site 32. The resealing in~ection site 32 allows the injection of a substance, for example a drug, through the injection port 12 into the container 17 to which the port assembly 10 i8 sealed.
Because the injection site 32 is resealing, the injection site 32 functions to provide a seal after the injection of the drug into the container 17. This has two functions: 1) to prevent microbial ingress into the container 17 through the injection port 12; and 2) to prevent leakage of the resultant product contained in the container 17, through the injection port 12. To provide a resealing construction, preferably, the injection site 32 is constructed from natural rubber.
The injection port 12, and more specifically, the tubular wall 22, provides a mechanical lock for securing ~ e~ 2 ~
the resealing injection site 32 within the injection port 12. To thi~ end, the in~ection port 12 includes a circular or ring-shaped flange 34 that oxtQnds outwardly from the pierceable membrane 26. The resealing injection S site 32 rests upon the flange 34. To lock the resealing injection site 32 into place, the flange 34 cooperates with a portion 36 of the tubular wall 22 that is bent over and defines a circular flange that circumscribe6, or overlaps, a portion of the resealing in~ection site 32. The portion 36 of the tubular wall and flange 34 function to lock the resealing injection site 32 within the in~ection port 12.
A preferred method of locking the in~ection site 32 in position is as follows. First, the in~ection port 12, and specifically, the tubular wall 22 is constructed.
The injection site 32 is then inserted within the upper portion 28 of the tubular bore 24. The injection port 12 is then ultrasonically welded 80 that the portion 36 of the tubular wall 22 i8 caused to be bent around and circumscribe the injection site 32. To this end, during the ultrasonic welding of the tubular wall 22, a force is applied to a top portion of the tubular wall 22 causing the top portion to be forced inwardly. This functions to seal and lock the resealing injection site 32 within the upper portion 28 of the injection port 12.
It should be noted, however, that any means of swaging over the portion 36 of the tubular wall 22 can be used.
For example, the portion 36 can also be swaged over by cold forming or hot forming.
Preferably, the tubular wall 22, as well as remaining portions of the port assembly 10, is constructed from polypropylene. ~ost preferably, the 13238~8 - a -port assembly 10 is constructed from a rubber modified polypropylene, such as a Xraton~odi~ed polypropylene.
In order to provide a sterile in~ection port 12, the injection port ~ 8 preferably covered by a removable closure 38. The closure 38 can be any known in the art.
Preferably, the closure 38 is a closure such as that set forth in Canadian patent application Serial No. 615,271, entitled: "Closure for a Port", and filed September 29, 1989 in the names of the inventors of this present 10- patent application.
Refarring now to Figure 3, the administration port 14 is illustrated. As illustrated, the administration port 14 includes a tubular wall 40 that defines a tubular bore 42. Located within the tubul~r bore 42 is a pierceable membrane 44. The pierceable membrane 44 divides the tubular bore 42 into an upper portion 46 and a lower portion 48.
The ad~inistration port 14 has a construction 80 that it is adaptable for receiving an administration set.
To provide a secure seal with such a set, in the embodiment of the invention illustrated, a top portion 50 of the tubular wall 40 is tapered. Similar to the injection port 12, to provide a sterile administration port 14, the port can be covered by a removable closure 54.
In constructing the embodiment of the port assembly 10 of the present invention illustrated, the in~ection port 12, administration port 14, and ba~e 16 are integrally constructed. The resealing injection site 32 is then positioned inside the bore 28 of the injection port 12. The injection s te 32 i5 then mechanically locked in place. Closures 38 and 54, respectively, are . ~
~323Q,Sg then positioned over the ln~ection port 12 and administration port 14. The port ~ssembly can then be secured to a container 17.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without dimini~hing its attendant advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
