Systems and methods for delivery of peritoneal dialysis (PD) solutions with integrated inter-chamber diffuser
First Claim
1. A container system for medical solutions, comprisingA) a first compartment that contains a first medical solution and that is fluidly couplable with an outlet of the container system that includes a frangible seal,B) a second compartment that contains a second medical solution, the second compartment being fluidly couplable with the first compartment via a fluid pathway-defining structure (hereinafter, “
- port”
),C) a diffuser for facilitating mixing of the first and second medical solutions that is disposed within and movable relative to the port, wherein the diffuser comprises a body that floats within the port, moving therein depending on a direction of solution flow through the port, wherein the body has one or more apertures to effect dispersion of any of the first and second medical solutions flowing from one of the compartments into the other compartment,wherein the one or more apertures of the diffuser each comprise one or more passages extending any of through the body of and along a surface of the diffuser,wherein the one or more apertures of the diffuser each facilitate two-way communication between the first and second compartments.

Abstract
The invention provides, in some aspects, a container system for medical solutions such as peritoneal dialysis (PD) solutions. The invention particularly features a system which includes a first compartment that contains a first medical solution, e.g., a PD osmotic agent, and a second compartment that contains a second medical solution, e.g., 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. To that end, a container system can include a diffuser that is disposed in a fluid pathway between the first and second compartments, e.g., to facilitate homogeneous mixing of the first and second PD agents. That diffuser is disposed within and moves relative to a structure, such as a port that defines the fluid pathway between those compartment. Thus, for example, the diffuser can comprise a body that “floats” within that pathway-defining structure and that moves from one end to the other (and/or to from points there between), depending on a direction of solution flow through the structure.
