Abstract
A blood treatment apparatus () defines first and second flow circuits (CC) separated by a dialyzer (). The second flow circuit (C) comprises return and withdrawal lines () for connection to a vascular system of a subject during a treatment session. After the treatment session, a control system causes an operator to connect the second flow circuit (C) to a first port () of a container (), the apparatus () to perform a rinseback procedure, the operator to disconnect the return line () from the vascular system and re-arrange the second flow circuit (C) to define a closed loop, and the apparatus () to draw residual liquid from the closed loop into the first flow circuit (C) through a dialyzer membrane (). To facilitate drainage of the residual fluid with a conventional line set, the second flow circuit (C) is connected to a second port () of the container () to include the container () in the closed loop, or the return and withdrawal lines () are connected in fluid communication with the first port of the container () through a three-way manifold coupling unit.
