The present invention refers to a container comprising a connection portion allowing for an easy, efficient and more hygienic connection of the container to a fluid dosing unit of a blood treatment device. According to the present invention the fluid dosing unit comprises a valve that fluidically closes the fluid dosing unit if no container is connected to the fluid dosing unit and that opens the fluid dosing unit upon connection of a container to the fluid dosing unit. Thus, undesired spillages potentially arising upon disconnection of the container from the fluid dosing unit can be avoided.

The present invention refers to a system and method for opening a concentrate container without the need for a human to directly handle the concentrate container and connecting the concentrate container to a blood treatment device. Aspects of the invention are directed to a container for concentrate and a blood treatment device.

The present invention refers to a system and method for connecting a concentrate container with a blood treatment device with improved hygiene. Furthermore, the invention refers to a container and blood treatment device to be used in a method according to the present invention.

The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

Disclosed are a method for whole blood filtration and a filter membrane structure for whole blood filtration, specifically including the following steps: (1) a filter membrane structure made up of at least two filtration membranes sequentially stacked from top to bottom is selected, and subjected to hemagglutinin treatment for later use; (2) a whole blood sample is added to the filter membrane structure for filtration; and (3) the filtered serum or plasma is collected. The filter membrane structure is composed of at least two filtration membranes stacked from top to bottom, and the pore sizes of the filtration membranes stacked gradually decrease from top to bottom, and the areas of the same gradually increase or are equal to each other from top to bottom.

A failsafe system for a medical fluid procedure, comprising a medical fluid processing apparatus comprising a sealer and a programmable controller driven by software, wherein the programmable controller is programmed to recognize a failure event from input from hardware components of the medical fluid processing apparatus. The system also comprises a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment configured to fit within the sealer. The programmable controller is configured to seal the tubing segment by activating the sealer surrounding the tubing segment in response to an occurrence of the failure event.
