New rinsing-back method for blood tubing using blood tubings with a line bypassing the blood pump segment

Abstract

New blood tubing is characterized by a line bypassing the blood pump segment. During the rinsing-back procedure using this blood tubing, once the initial steps, which take 25∼30 seconds, have been completed, the dialysis center staff can attend to other patients, emergency situations etc., while rinsing-back of the blood tubing is ongoing. Moreover, in the case of an earthquake or blackout, use of the new rinsing-back approach, which abandons 16∼36mL of blood in the blood tubing on the arterial needle side of the rinse-fluid-line connection and blood pump segment, one dialysis staff member can complete the rinsing-back of blood tubings for 30 patients within 3∼4 min.
