Signal Activated Method for Draining an Effluent Bag and Devices

An effluent bag draining apparatus comprising:

• an effluent outlet line for guiding effluent out of an effluent bag;
• a pump section for conveying effluent out of the effluent bag;
• and
• a control device programmed to prompt the pump section to convey effluent out of the effluent bag when a predetermined draining time point is reached.

A system comprising a blood treatment apparatus and an effluent bag draining apparatus, wherein the blood treatment apparatus comprises a control device or closed-loop control device programmed for controlling or regulating the blood treatment apparatus during a treatment session that treats a patient's blood and that is carried out by an extracorporeal blood tubing set, wherein the blood treatment apparatus, while balancing liquid flows, conveying using a filtrate pump, conveying using a substituate pump, and/or conveying, using a dialysis liquid pump, wherein the control device or closed-loop control device is further programmed to, at one or more predetermined interruption time points that fall within the duration of the treatment session:

• interrupt a balancing of the liquid flows, and/or
• interrupt a calcium solution flow or a conveying action of a calcium pump, a citrate solution flow or a conveying action of a citrate pump, a Heparin solution flow or a conveying action of a Heparin pump, a filtrate flow or a conveying action of the filtrate pump, a substituate flow or a conveying action of a substituate pump, and/or a dialysis fluid flow or a conveying action of a dialysis liquid pump, and
• wherein the effluent bag draining apparatus comprises:
• an effluent outlet line for guiding effluent out of an effluent bag;
• a pump section for conveying effluent out of the effluent bag;
• and
• a control device programmed to prompt the pump section to convey effluent out of the effluent bag when a predetermined draining time point is reached.

A method for draining an effluent bag filled with effluent during a patient's blood treatment using a blood treatment apparatus and an effluent bag draining apparatus comprising an effluent outlet line for guiding effluent out of an effluent bag, a pump section for conveying effluent out of the effluent bag, and a control device programmed to prompt the pump section to convey effluent out of the effluent bag when a predetermined draining time point is reached, wherein an effluent bag, which comprises an effluent outlet opening, is in fluid communication with the blood treatment apparatus and/or is connected to the effluent bag draining apparatus, wherein the effluent outlet opening of the effluent bag is connected to the effluent outlet line of the effluent bag draining apparatus to conduct effluent out of the effluent bag, such that a fluid communication is established between an interior space of the effluent bag and an interior space of the effluent outlet line, wherein the method comprises:

• at one or more predetermined interruption time points that fall within a duration of a treatment session:
• stopping a balancing;
• and/or
• stopping a calcium solution flow or a conveying action of a calcium pump, a citrate solution flow or a conveying action of a citrate pump, a substituate solution flow or a conveying action of a substituate pump, a Heparin solution flow or a conveying action of a Heparin pump, a filtrate flow or a conveying action of a filtrate pump and/or a dialysis liquid flow or a conveying action of the dialysis liquid pump;
• and
• prompting the pump section to convey effluent out from the effluent bag when a predetermined draining time point is reached.
