Systems and methods for delivery of peritoneal dialysis (PD) solutions
First Claim
1. A method of dispensing a peritoneal dialysis solution from a peritoneal dialysis (PD) container system, comprising the steps of:
- A. breaking a first seal in a PD container system of the type comprising a first compartment containing a first PD agent and a second compartment containing a second PD agent,B. sliding a protective member from a first position, wherein it inhibits breaking of a second seal, to a second position, andC. breaking the second seal to allow fluid to exit the container system via an outlet, wherein a presence of a quantity of fluid in the second compartment prior to breaking of the first seal inhibits sliding of the protective member.

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.

20. A method of dispensing a peritoneal dialysis solution from a peritoneal dialysis (PD) container system, comprising the steps of:
-
A. breaking a first seal in a PD container system of the type comprising a first vessel defining a first compartment that contains a PD osmotic agent and a second vessel defining a second compartment that contains a PD buffer agent, B. squeezing, twisting or otherwise manipulating the second vessel in order to break a frangible seal disposed within the second compartment 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, wherein a presence of a quantity of fluid in the second compartment prior to breaking of the first seal inhibits breaking the frangible seal. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method of dispensing a peritoneal dialysis solution from a peritoneal dialysis (PD) container system, comprising the steps of:
-
A. breaking a first seal in a PD container system of the type comprising a first vessel defining a first compartment that contains a first PD first and a second vessel defining a second compartment that contains a second PD agent, and B. inhibiting breakage of a second seal that prevents fluid transfer between the second compartment and an outlet fluid pathway of the container system with a presence of a quantity of the second PD agent in the second compartment prior to breaking of the first seal.
