Systems and Methods for Delivery of Peritoneal Dialysis (PD) Solutions
First Claim
1. A vessel for storing 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,at least one of the first and second compartments being adapted to be manipulated at least partially independently of the other of said first and second compartments.a first seal preventing fluid transfer between the first compartment and the second compartment, anda second seal preventing fluid transfer between the second compartment and an outlet fluid pathway of the vessel,the vessel adapted to deter breaking of the second seal prior to breaking of the first seal.

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.

9. A vessel comprising:
-
a first compartment containing a first agent of a solution, a second compartment containing a second agent of the solution, the second compartment being in any of direct and indirect fluid coupling with the first compartment, at least one of the first and second compartments being adapted to be manipulated at least partially independently of the other of said first and second compartments. a first seal preventing fluid transfer between the first compartment and the second compartment, and a second seal preventing fluid transfer between the second compartment and an outlet fluid pathway of the system, a protective member coupled to the vessel to deter breaking of the second seal prior to breaking of the first seal. - View Dependent Claims (10, 11, 12, 13, 18)

15. The vessel of claim 14, wherein the protective member is slidably disposed on the system and adapted to move from a first position, wherein the protective member inhibits breaking of the second seal, to a second position, wherein the protective member does not inhibit breaking of the second seal.
- 16. The vessel of claim 14, wherein, prior to breaking of the first seal, movement of the protective member from the first position to the second position is restrained by the second compartment.

19. A container system for storing a plurality of fluids, comprising:
-
a vessel having a first chamber and a second chamber, the second chamber being in any of direct and indirect fluid coupling with the first chamber, a first seal preventing fluid transfer between the first chamber and the second chamber, a second seal preventing fluid transfer between the second chamber and an outlet fluid pathway of the container system, and a port fluidly coupling the first chamber and the second chamber, the port comprising the first seal and a diffuser, the diffuser adapted to facilitate mixing of fluids upon expulsion of fluid from the second chamber to the first chamber. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
