A container system includes at least one flexible wall defining a compartment containing a dissolvable solid or concentrate, a support adjacent a first end of the at least one flexible wall, and a nozzle assembly coupled to a second end of the at least one flexible wall. The second end of the wall is distal from the first end. The nozzle assembly comprises a hollow body defining a longitudinal axis. The hollow body further defines a plurality of orifices through a wall thereof. Each orifice is able to form a fluid connection between an interior volume within the hollow body and the compartment. Each orifice is configured to deliver liquid from the interior volume to the compartment in a direction having an angle of between 5° and 85° from a direction of the longitudinal axis. Related nozzles and methods are also disclosed.

Flexible container systems and nozzles, and related methods

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.

A medical fluid delivery cassette configured for use with a medical fluid pumping system and related systems and methods. The medical fluid delivery cassette includes a base and a membrane that together define a fluid pump chamber. The medical fluid delivery cassette further includes a member configured to apply an outward force to an inner surface of the membrane.

Medical fluid cassettes and related systems and methods

This disclosure relates to medical fluid pumping systems and related devices and methods. In some aspects, a medical fluid pumping system includes a medical fluid pumping machine including a piston head that can be linearly displaced and a medical fluid cassette that can be secured to the medical fluid pumping machine. The medical fluid cassette includes a fastening member attached to a region of a flexible membrane overlying a fluid pump chamber, and the piston head is configured to be mechanically connected to the fastening member of the cassette.
