An airtrap for a medical or physiological fluid in one embodiment includes a conical housing having a radius that increases from its top to its bottom when the housing is positioned for operation; a medical or physiological fluid inlet located at an upper portion of the conical housing; a medical or physiological fluid outlet located at a lower portion of the conical housing, the inlet and the outlet positioned and arranged so that medical or physiological fluid spirals in an increasing arc around an inside of the conical housing downwardly from the inlet to the outlet; and a gas collection area located at an upper portion of the conical housing. In another embodiment, the airtrap is shaped like a seahorse having a head section and a tail section. Any of the airtraps herein may be used for example in blood sets, peritoneal dialysis cassette tubing, and drug delivery sets.

Airtrap, system and method for removing microbubbles from a fluid stream

The application discloses an apparatus and method for processing biological material, including a suspension of cells.

Apparatus and method for processing biological material

In an embodiment, a dialysis fluid cassette is disclosed. The cassette includes a plurality of walls defining at least one valve chamber, a dialysis fluid inlet, a dialysis fluid outlet and a dialysis fluid pathway. The cassette further includes a baffle extending from a first one of the walls to an opposing second one of the walls. The baffle includes an end fixed to a third one of the plurality of walls and a free end. The fixed end separates the dialysis fluid inlet from the dialysis fluid outlet and the baffle and the plurality of walls are constructed and arranged such that the flow of dialysis fluid along the pathway defined in part by the baffle slows as the flow approaches the free end of the baffle.

Dialysis systems and methods including cassette with air removal

A dialysis fluid system includes an instrument including a pump actuator and a fluid heater, and a dialysis fluid cassette. The dialysis fluid cassette includes a rigid portion defining a pumping section for operation with the pump actuator and a heating section for operation with the fluid heater. The heating section includes a dialysis fluid inlet, a dialysis fluid outlet, and a dialysis fluid heating area located between the fluid inlet and the fluid outlet, the heating section further includes an air separation chamber for collecting air separated from the dialysis fluid.

Dialysis systems and methods including cassette with fluid heating and air removal

A dialysis system includes a dialysis fluid disposable configured to hold and transport a dialysis fluid; an air separation chamber in fluid communication with the dialysis fluid disposable; and a dialysis instrument operable to pump dialysis fluid through the dialysis fluid disposable, the instrument including a vibrator configured to vibrate the air separation chamber to separate air from the dialysis fluid traveling through the chamber.

Dialysis systems and methods having vibration-aided air removal

A medical fluid delivery system includes a fluid disposable configured to hold and transport a medical fluid and an air separation chamber in fluid communication with the fluid disposable. The air separation chamber includes at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber.

Fluid delivery systems and methods having floating baffle aided air removal

A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including an inner surface, a fluid inlet and a fluid outlet and configured to cause a dialysis fluid to spiral around the inner surface toward the fluid outlet, such that air is removed from the dialysis fluid.

Dialysis systems having spiraling fluid air separation chambers

A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including a first sidewall and a second sidewall, a first fluid opening, a second fluid opening, and a separation wall extending from the first sidewall to the second sidewall, the separation wall having a free edge residing within the air separation chamber, the separation wall forcing the dialysis fluid to flow from one of the fluid openings around the free edge of the separation wall to the other of the openings.

Dialysis systems having air separation chambers with internal structures to enhance air removal

A dialysis fluid cassette includes a rigid portion defining first and second valve chambers, the rigid portion further defining an air separation chamber in fluid communication with the first and second valve chambers, the air separation chamber including a baffle and structured such that when the cassette is placed in a dialysis instrument, (i) the baffle extends upwardly from a bottom of the air separation chamber and (ii) first and second openings to the air separation chamber, communicating fluidly and respectively with the first and second valve chambers, are located near the bottom of the air separation chamber, such that the dialysis fluid is forced up one side of the baffle and down the other side of the baffle when flowing through the air separation chamber.
