This disclosure relates to medical fluid cassettes and related systems and methods. In certain aspects, a medical fluid cassette includes a base having a first region and a second region, a first membrane overlying the first region of the base, and a second membrane overlying the second region of the base. The second membrane is configured to rebound away from the base when a force used to press the second membrane toward the base is released.

Medical fluid cassettes and related systems and methods

In some aspects, a dialysis machine support assembly includes a platform configured to support a dialysis machine and a drive assembly configured to move the platform vertically.

Dialysis machine support assemblies and related systems and methods

A peritoneal dialysis system includes a base peritoneal dialysis system and a peritoneal dialysis fluid exchange system that operates independently of the base system. The base system includes a first cassette including a first patient line configured to be connected to a patient, and a PD cycler. The PD cycler receives the first cassette, and includes a pump that cooperates with the first cassette to deliver dialysate to and drain dialysate from a peritoneal cavity of the patient via the first patient line. The peritoneal dialysis fluid exchange system includes a second cassette including a second patient line configured to be connected to the patient and a fluid exchange device that receives the second cassette. The fluid exchange device includes a data exchange interface operable to transfer patient treatment data from the peritoneal dialysis fluid exchange system to the base peritoneal dialysis system.

Peritoneal dialysis systems and related devices 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.

Medical fluid pumping systems and related devices and methods

A medical fluid pumping system that includes a medical fluid pumping machine that includes an actuator and a medical fluid cassette that can be disposed within a cassette enclosure of the medical fluid pumping machine. A member is disposed within a fluid pump chamber of the medical fluid cassette and is magnetically attracted to the actuator such that the member and the actuator can be coupled together when the cassette is disposed within the cassette enclosure.

This application relates to a dialysis machine support assembly that includes a platform configured to support a dialysis machine and a drive assembly configured to move the platform vertically. A control unit can monitor input data from a sensor of the dialysis machine when the dialysis machine is supported by the platform and can operate the drive assembly to adjust a vertical position of the platform based on the input data.

Piston head for a peritoneal dialysis cycler

This disclosure relates to medical fluid delivery sets and related systems and methods. In some aspects of the invention, a medical fluid cassette includes a plunger slidably disposed within a recess of a base of the cassette such that a substantially liquid-tight seal is maintained between the plunger and the base as the plunger slides axially within the recess. The plunger and the base cooperate to at least partially define a fluid pump chamber. When the plunger is displaced in a first direction, fluid is forced out of the fluid pump chamber, and when the plunger is displaced in a second direction, fluid is drawn into the fluid pump chamber.
