1. An apparatus for peritoneal dialysis (PD), comprising:
- a PD-cycler;
a tube set connected to the PD-cycler;
a PD-fluid source connected to the tube set;
a heater bag connected, via the tube set, to the PD-fluid source, wherein the heater bag temporarily stores and heats the PD-fluid received from the PD-fluid source before introduction to a patient;
a drain bag connected to the tube set, wherein the drain bag receives spent PD-fluid from the patient;
a waste receiver connected to the tube set, wherein the waste receiver at least receives PD-fluid from the drain bag;
a valve pack connected to the PD-cycler comprising a plurality of valves operable on the tube set to control flows of fluids through the tube set; and
a transfer member arranged to connect the heater bag and the waste receiver,wherein one of the valves operable on the tube set operates to keep the transfer member closed during PD-treatment and open after completion of PD-treatment,wherein when the transfer member is open after completion of PD-treatment,the transfer member is configured to transfer the PD-fluid in the heater bag to the waste receiver, andthe PD-fluid remaining in the PD-fluid source is directed via the transfer member to the waste receiver by actuation of at least another one of the valves operable on the tube set.

Abstract
PD-cycler and tube set therefor and a method for use thereof. The tube set includes a transfer member for automatic transfer of possibly remaining contents in supply bags or heater bags of the tube set to a waste receiver. A separate connection unit is arranged in connection with a valve pack of the PD-cycler. The connection unit has a rod of ferromagnetic material which allows an indication that the tube set is in the correct position. The beater and drain bags are combined into a double bag which is supported by a yoke in a folded state, which is unfolded upon application into the PD-cycler.
