Abstract: 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.

Abstract: A blood filtration system may include blood circuit configured to transmit a fluid within one or more lumens. The system may include an optical sensor configured to couple with the blood circuit. The optical sensor may measure one or more optical characteristics of the fluid in the blood circuit. The one or more optical characteristics may include a first optical characteristic corresponding to a concentration of an imaging substance in the fluid within the blood circuit. The system may include a controller in communication with the optical sensor. The controller may include a sampling module configured to record the one or more optical characteristics. The controller may include a physiological characteristic identification module configured to determine a plasma volume of the patient with the recorded optical characteristics of the imaging substance.

Abstract: A blood filtration system may to couple to an infusion pump that is external to the blood filtration system. The blood filtration system may include a blood circuit, for instance a variable-volume blood circuit. An infusion port may be in communication with the blood circuit and may receive an infusion fluid pumped by the infusion pump. A filtration pump may extract a filtrate fluid from a filter. The filtrate fluid may include filtered plasma constituents. A fluid characteristic sensor may measure one or more of pressure or flow rate of the infusion fluid pumped by the infusion pump. A controller may monitor the fluid characteristic sensor to determine a change in the pressure or flow rate of the infusion fluid. The controller may modulate a speed of the variable-speed filtration pump based on the change in the pressure or flow rate of the infusion fluid.
