Abstract
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.
Claims20
A dialysis system comprising:
- a dialysis fluid disposable including a disposable cassette having a flexible pumping sheet, the 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 configured 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.
A dialysis system comprising:
- a dialysis fluid disposable including a pump chamber, the dialysis fluid disposable configured to hold and transport a dialysis fluid;
- and
- a dialysis instrument configured to pump dialysis fluid through the dialysis fluid disposable, the instrument including a vibrator configured to vibrate the pump chamber of the dialysis fluid disposable to separate air from the dialysis fluid traveling through the dialysis fluid disposable.
A dialysis method comprising:
- flowing a dialysis fluid by flexing a flexible sheet of a pump chamber;
- removing air from the dialysis fluid using buoyancy forces;
- and
- removing air from the dialysis fluid using vibration forces applied to the pump chamber or to an air separation chamber in fluid communication with the pump chamber.
