Patent number: 11420037Abstract: A method of operating an extracorporeal blood treatment system to infuse blood into a patient at an end of an extracorporeal blood treatment includes clamping an access line of an arterial line set. The method further includes, after clamping the access line, initiating an operation to generate negative pressure in the arterial line set. The method further includes, after generating the negative pressure in the arterial line set, unclamping the access line to draw fluid in the access line further into the arterial line set in a direction away from an end of the access line that is connectable to an arterial access of the patient. The method further includes initiating an operation of a fluid pump engaged with the arterial line set such that the fluid in the arterial line set is infused into the patient through a venous line set.Type: GrantFiled: August 4, 2017Date of Patent: August 23, 2022Assignees: Fresenius Medical Care Holdings, Inc., Fresenius Medical Care Deutschland GmbHInventors: Martin Joseph Crnkovich, David Yuds, Christian Schlaeper
