Systems and methods for delivery of peritoneal dialysis (PD) solutions
First Claim
1. A container system for peritoneal dialysis (PD) solutions, comprising:
- A. a first compartment containing a first PD agent,B. 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 vessel in which the second compartment is formed expelling second PD agent upon application of force,C. a first frangible seal that prevents fluid transfer between the first compartment and, the second compartment,D. a second frangible seal that prevents fluid transfer between the second compartment and an outlet fluid pathway of the container system,E. a protective member slideably disposed on the container system to move from a first position, wherein it inhibits breaking of the second frangible seal, to a second position, wherein it does not inhibit breaking of the second frangible seal, wherein the protective member has a slot or other opening sized to slide over at least a portion of the vessel in which the second compartment is formed and wherein presence of a quantity of second PD agent in the second compartment inhibits the slot or other opening from sliding over at least the portion of the vessel forming the second compartment.

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.

14. A container system for peritoneal dialysis (PD) solutions, comprising:
-
A. a first compartment containing a first PD agent, B. 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 vessel in which the second compartment is formed folding upon application of force and expelling second PD agent in connection therewith, C. a first seal that prevents fluid transfer between the first compartment and the second compartment, D. a second seal that prevents fluid transfer between the second compartment and an outlet fluid pathway of the container system, E. a protective member slideably disposed on the container system to move from a first position, wherein it inhibits breaking of the second seal, to a second position, wherein it does not inhibit breaking of the second seal, F. the protective member including a slot or other opening is configured to slide over at least a portion of the vessel in which the second compartment is formed only if two or more sides thereof are aligned with the slot and that vessel is at least partially folded, G. the first and second seals being adapted for breakage via manipulation by a patient, health care provider, or other. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
