Multi-chambered containers having peelable seals and methods of sterilizing the same are provided. In an embodiment, the present disclosure provides a flexible fluid container comprising a first chamber and a second chamber. The second chamber is attached to a tube for providing fluid communication from the second chamber to the exterior of the container. The first chamber and the second chamber are separated by a first peelable seal having a channel so constructed and arranged to allow a controlled quantity of fluid to pass therethrough.

The present invention provides a peelable polymeric layer structure having a first sealant layer including an ethylene-containing polymer, and a second sealant layer including a polypropylene-containing polymer attached to the first sealant layer along a peelable seal. The present invention also provides an overpouch container including a first sidewall having a first sealant layer of an ethylene-containing polymer, and a second sidewall having a second sealant layer of a propylene containing polymer. The second sealant layer is attached to the first sealant layer along a peelable peripheral seal.

A container system for containing and preserving gas generating solutions such as bicarbonate-containing solutions is provided. The system includes an outer container or barrier that is gas impermeable. The system also includes an indicator for visually indicating when gas has been permitted to leak or escape from the outer container thereby changing the physical characteristics of the gas generating solution.

The present disclosure provides a multiple chamber container that includes a container body sealed around a peripheral edge and having an outlet. The container also includes a first peel seal having a projecting portion and a second peel seal that isolates the outlet. The second peel seal may also include a projecting portion. The first and second peel seals may be configured to define a symmetrical chamber. The chamber may include an axis of symmetry extending between the first and second projecting portions. The chamber geometry of the container ensures a correct sequential opening of the first and second peel seals.

The present invention provides devices and methods for stabilizing bicarbonate-based solutions for peritoneal dialysis or hemofiltration. The bicarbonate-based solutions of the present invention are formulated and stored in at least two parts—an alkaline bicarbonate concentrate and an acidic concentrate. The alkaline bicarbonate concentrate is adjusted to have a pH of about 8.6 to 10.0. The acidic concentrate is adjusted to have a stable, acidic pH ranging from about 1.0 to 3.0. Upon mixing, although some variation in the pH of the mixed bicarbonate solution exists, the inventors have discovered that with the appropriate selection of the parameters of the concentrates, the pH of the mixed solution is always within an acceptable physiological range.

A formed, filled, and sealed container, access port and method for establishing fluid flow from the container to an administrative set is provided. The container is collapsible and has an inlet and an outlet. A hollow port is sealed to the container and a perforator inside the port pierces and becomes embedded in the container. Solution in the container is withdrawn into the port. A line attached to the port and an administrative set further establishes flow between the container and the administration set. The port may be operated with a single-hand to establish fluid flow from the container to the administrative set. After the perforator is embedded in the container, a lock on the port prevents the perforator from removal from the container. Activation of the lock produces an audible and/or visible notification.

A method and device for stabilizing and storing bicarbonate solutions is provided. In an embodiment, a device is provided having a container and carbon-dioxide generating substances that include a solid material which upon contact with water generates carbon-dioxide gas. The device may be packaged together with the bicarbonate or in a separate overpouch. The present invention also provides a method for the stabilization of bicarbonate solutions utilizing a means that generates high pressure carbon dioxide.
