A medical fluid treatment system includes a source of purified water; at least one concentrate for mixing with the water from the source to form a treatment fluid; a disposable set including a pumping portion, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a patient line in fluid communication with the pumping portion, the patient line including a filter having a membrane configured to filter the treatment fluid, the filter configured such that (i) fresh treatment fluid flowing from the pumping portion towards a patient flows through the membrane and (ii) used treatment fluid flowing through the filter from the patient to the pumping portion bypasses the membrane; and a medical fluid delivery machine including a pump actuator operable with the pumping portion of the disposable set.

A peritoneal dialysis system includes a water purifier, a cycler, and a disposable set operable with the cycler. The disposable set includes a pumping cassette including a water inlet port, a heater/mixing container in fluid communication with the pumping cassette, a water accumulator, a first water line segment, and a second water line segment. The first water line segment is in fluid communication with the water inlet port and the water accumulator. Additionally, the second water line segment is in fluid communication with the water accumulator and the water purifier.

A peritoneal dialysis system includes a cycler including a pump actuator, a heater and a heating pan operable with the heater, and a disposable set operable with the cycler. The heating pan includes a sidewall forming a slot. The disposable set includes a pumping cassette and a heater/mixing container. The pumping cassette includes a pump chamber configured to be actuated by the pump actuator. Additionally, the heater/mixing container is in fluid communication with the pumping cassette and is sized to be received at the heating pan. The heater/mixing container includes a port configured such that when the port is slid into the slot of the heater pan sidewall, the port is prevented from rotating about an axis transverse to a direction of flow through the port.

A medical fluid delivery system includes a source of purified water; a source of concentrate for mixing with water from the water source; a disposable set including a pumping portion, a water line in fluid communication with the source of purified water and the pumping portion, the water line including a filter for filtering the water, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a heater/mixing container in fluid communication with the pumping portion; a medical fluid delivery machine including, a pump actuator operable with the pumping portion of the disposable set, and a heater/mixing pan configured to support the heater/mixing container; and at least one leveling foot positioned and arranged to enable the heater/mixing pan to be oriented in a desired position for mixing the concentrate and purified water. A leveling tray and leveling foot are provided additionally.

A valve assembly for permitting fluid flow in a first direction and for preventing fluid flow in a second direction opposite to the first direction. The valve assembly includes an upper housing, a lower housing coupled to the upper housing to form a generally axially extending housing assembly, and a valve seating section defined within an inner peripheral portion of the lower housing. The valve seating section includes an axially extending inner peripheral surface and a transversely extending surface substantially normal to the axially extending inner peripheral surface. A valve member is seated within the valve seating section of said lower housing. The valve member includes a flange that extends from the valve member in a transverse direction and defines an axially oriented outer peripheral surface thereof. The valve member is retained within the valve seating section of the lower housing by the axially extending inner peripheral surface of the valve seating section transversely compressing the axially oriented outer peripheral surface of the flange to form a press-fit therebetween. Further, the valve member also includes a lower transverse surface which is axially separated from the transversely extending surface of the valve seating section, in which an air space is defined between these two transverse surfaces.
