Abstract
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.
Claims23
A medical fluid delivery system comprising:
- 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 including at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber, wherein the at least one floating fluid baffle includes:
- (i) plural particles, (ii) a coiled strip, or (iii) a twisted strip.
A medical fluid delivery system comprising:
- an instrument configured to pump medical fluid through an air separation chamber, the air separation chamber including at least one fluid baffle floating within the air separation chamber and configured to separate air from the medical fluid pumped through the chamber, wherein the floating fluid baffle includes:
- (i) plural particles, (ii) a coiled strip, or (iii) a twisted strip.
A fluid delivery method comprising:
- flowing a medical fluid;
- removing air from the medical fluid using buoyancy forces;
- and
- floating at least one coiled or twisted strip in the fluid to remove air from the medical fluid by disrupting the flow of medical fluid.
A medical fluid delivery system comprising:
- 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 including at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber, wherein the at least one fluid baffle is textured to produce additional surface contact area for removing air from the medical fluid.
A medical fluid delivery system comprising:
- a fluid disposable including a flexible pumping sheet, the 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 including at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber.
A fluid delivery method comprising:
- flowing a medical fluid;
- removing air from the medical fluid using buoyancy forces;
- and
- floating a plurality of at least substantially spherically shaped particles in the fluid to remove air from the medical fluid by disrupting the flow of medical fluid.
