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.

An optimizing device for freely switching RBC removal and plasma exchange are provided, which is used to solve the problems in the prior art that the treatment effect is poor, the consumption of consumables is excessive, and the application range is narrow. According to the device, an additional hanging hook is added, a plasma exchange output pipeline is modified to be separated from the plasma collection pump and to be installed to the additional hanging hook. Then, the RBC recirculation tube is clamped through a freely movable cassette, so that the flow rate control of a plasma collection pump is released. Thereafter, HCT data is adjusted, and liquid is compensated, so that the RBC removal or replacement, lymphoplasma exchange and plasma exchange can be freely switched, which can meet the clinical treatment needs, optimize the process and reduce the cost. Therefore, the application range of a pipeline is greatly increased.
