摘要： Dialysis systems that remove air from a blood circuit are disclosed herein. In an embodiment, a dialysis system includes a dialysis fluid circuit, a blood circuit including an arterial line, a venous line, and an enclosure in fluid communication with the venous line, the enclosure configured to release air through a hydrophobic vent for priming the blood circuit, a blood pump configured to pump fluid through at least the arterial line, a first valve operable with the arterial line and a second valve operable with the venous line, and a pumping and valving algorithm operated after priming to remove air from the blood circuit to control the first and second valves and the blood pump to replace priming fluid with blood from a patient.

摘要： A hemodialysis system configured to purge air from a blood circuit comprises a dialyzer; a dialysis fluid circuit operable with the dialyzer via dialysis fluid inlet and outlet lines, the dialysis fluid circuit including a fresh dialysis fluid pump, and a used dialysis fluid pump; the blood circuit operable with the dialyzer and including an arterial line, a venous line, a blood pump operable with the arterial line upstream of the dialyzer, a physiologically acceptable fluid source in fluid communication with the arterial line upstream of the blood pump, a drip chamber located along the venous line, and a container for accepting air purged from the blood circuit; and an air purging scheme wherein, with the dialysis fluid inlet and outlet lines connected to the dialyzer, the blood pump pumps a fluid through the dialyzer and into the drip chamber, forcing air from the drip chamber into the container.

摘要： A blood treatment air purging system and method includes a level detector positioned and arranged to detect a low fluid level in a blood circuit indicating a high amount of air in the blood circuit; a blood pump operable with the blood circuit; a venous patient line of the blood circuit; and at least one blood circuit air vent valve, wherein the system and method are configured or programmed to (i) stop the blood pump, (ii) close the venous patient line, and (iii) open the at least one blood circuit air vent valve to atmosphere or a container when the low fluid level is detected, and (iv) run the blood pump to meter air through the at least one blood circuit air vent valve to atmosphere or the container.
