A method for temporarily interrupting an extracorporeal treatment of blood of a patient by use of a blood treatment apparatus includes activating or controlling a control device which is provided and configured to bring the blood treatment apparatus into a state in which the blood treatment session of the patient can be interrupted with the intention to continue the blood treatment session. The present invention further provides a control device, a blood treatment apparatus, a digital storage means, a computer program product as well as a computer program.

A method of removing blood from an extracorporeal blood circuit and/or a functional device, each of which is connectable or connected with a blood treatment apparatus for the purpose of a blood treatment of a patient, after concluding a blood treatment session, the method comprising operating a blood pump in a second conveying direction which is opposite to a first conveying direction of the blood pump which is customary during the blood treatment, and an arterial line section of the extracorporeal blood circuit is or will be connected with a venous line section of the extracorporeal blood circuit.

The present invention provides an extracorporeal dialysis apparatus which allows the automation of some operations in order to make possible a safe home treatment or to facilitate the treatment process for example the priming and/or the blood return process. Thus, the object is to automatically perform a series of processes from hemodialysis preparation to treatment completion safely, reliably and speedily, and to significantly reduce the labor and supply costs.

This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.

Disclosed are hemodialysis and similar dialysis systems including fluid flow circuits. Hemodialysis systems may include a blood flow path, and a dialysate flow path including balancing, mixing, and/or a directing circuits. Preparation of dialysate may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit and/or the various fluid flow paths may be isolated from electrical components. A gas supply may be provided that, when activated, is able to urge dialysate through the dialyzer and blood back to the patient. Such a system may be useful during a power failure. The hemodialysis system may also include fluid handling devices, such as pumps, valves, mixers, etc., actuated using a control fluid. The control fluid may be delivered to the fluid handling devices using a detachable external pump. The fluid handling devices may have a spheroid shape with a diaphragm dividing it into two compartments.

A blood purification apparatus is provided that allows setting work at the time of blood purification treatment or preparation for the treatment to be easily and smoothly performed. The blood purification apparatus includes: a circuit for blood purification having an arterial blood circuit and a venous blood circuit that constitute a blood circuit; a dialyzer for purifying the blood extracorporeally circulated by the blood circuit; and a dialysis device main body, wherein the blood purification apparatus includes an identification means that allows specific information to be identified, the specific information including an operating condition of the circuit for blood purification or the dialyzer at the time of blood purification treatment or preparation for the treatment, a reading means by which the specific information of the identification means is readable, and a control unit that performs blood purification treatment or preparation for the treatment based on the operating condition in the specific information read by the reading means.

An attaching member attachable to a blood purification apparatus including a peristaltic pump, the attaching member holding a pump tube to be squeezed in a predetermined direction by the peristaltic pump for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and a holding portion attached to the body and that holds the pump tube. The holding portion holds the pump tube such that the pump tube is inclined in a direction in which the pump tube is attached to the peristaltic pump.

An extracorporeal blood filtering machine can include a blood circuit, an effluent circuit, and a source fluid circuit and can be controlled by a controller. The extracorporeal blood filtering machine can also include access ports for connecting the source fluid circuit to the blood circuit, as well as blood sensors to detect possible issues with the extracorporeal blood filtering machine. The extracorporeal blood filtering machine can include density sensors and flow sensors that enable it to be more accurate and to operate while being transported. The extracorporeal blood filtering machine can further include a user interface and can display fluid inflow/outflow information. A medical fluid container can automatically empty after being filled. An apparatus for supporting a medical fluid container can include a hanger and an attachment member with the apparatus able to adjust to ensure the medical fluid container remains properly oriented directly under a medical fluid container scale.
