Abstract
The invention provides container systems, kits and methods for peritoneal dialysis (PD) solutions. Such a system, for example, includes a first compartment that contains a PD osmotic agent and a second compartment that contains a PD buffer agent. The compartments maintain their respective contents separately from one another for purposes of transport, storage and/or sterilization. However, the compartments are fluidly couplable, so that their respective contents can be combined with one another, e.g., following sterilization of the agents and prior to their introduction into the patient'"'"'s abdomen. The invention provides, in other aspects, such systems, kits and methods that provide protective structure which inhibits breaking of a seal prior between the second compartment and an outlet of the system, prior to breaking of a seal between the first and second compartments.

64. A container system for peritoneal dialysis (PD) solutions, comprising:
-
a first compartment containing a first PD agent, a second compartment containing a second PD agent, the second compartment being in any of direct and indirect fluid coupling with the first compartment, a first seal preventing fluid transfer between the first compartment and the second compartment, and a second seal preventing fluid transfer out of the second compartment of the container system, the container system configured to inhibit breaking of the first seal and the second seal at the same time. - View Dependent Claims (65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86)

87. A container system for peritoneal dialysis (PD) solutions, comprising:
-
a first compartment containing a first PD agent, a second compartment containing a second PD agent, the second compartment being in any of direct and indirect fluid coupling with the first compartment, an outlet fluid pathway coupled to the second compartment being in any of direct and indirect fluid coupling with an external environment to the container system, and a seal that prevents fluid transfer between the first compartment and the second compartment, the container system further configured to inhibit fluid transfer to the outlet fluid pathway prior to mixing of at least a portion of the first PD agent and the second PD agent. - View Dependent Claims (88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105)

106. A method of dispensing a peritoneal dialysis (PD) solution from a PD container system, comprising:
-
providing the PD container comprising; (i) a first compartment containing a first PD agent, (ii) a second compartment containing a second PD agent, the second compartment being in any of direct and indirect fluid coupling with the first compartment, and (iii) a first seal preventing fluid transfer between the first compartment and the second compartment, and inhibiting fluid transfer out of the PD container prior to mixing the first PD agent with the second PD agent. - View Dependent Claims (107, 108)

109. A method of dispensing peritoneal dialysis (PD) solution from a PD container system, comprising:
-
breaking a first seal in a PD container system of the type comprising;
a first compartment that contains a first PD agent and a second compartment that contains a second PD agent, andsqueezing, twisting or otherwise manipulating the second compartment to break a frangible seal that prevents fluid transfer between the second compartment and an outlet fluid pathway of the container system to allow fluid to exit the container system via the outlet.
