Abstract:
1. A blood priming method comprising: (a) running a dialysate pump to pull blood from a patient into an extracorporeal blood circuit in a first direction thereby displacing a priming liquid to a drain until or after blood is detected in the extracorporeal blood circuit by flowing the priming liquid through a line connecting the extracorporeal blood circuit to the drain so that priming liquid does not pass directly through a blood filter to a dialysate circuit; and (b) running a blood pump to pull blood from the patient into the extracorporeal blood circuit in a second direction thereby displacing the priming liquid to the drain until or after blood reaches an air trap in the extracorporeal blood circuit by flowing the priming liquid through the line connecting the extracorporeal blood circuit to the drain so that priming liquid does not pass directly through the blood filter to the dialysate circuit.
