A recently granted patent (Publication Number: US11918720B2) discloses a multiple treatment fluid stream system designed for extracorporeal blood treatment and extracorporeal membrane oxygenation. The system includes a multi-stream treatment machine with at least two pumps, one being a blood pump and the other a multiple-fluid pump for various fluids. An accessory fluid circuit with parallel pumping tube segments splits the blood stream into two paths, combining them later for treatment. The system can be configured for delivering hemodialysis treatment and includes instructions for operating the multiple-fluid pump in reverse for specific modes.

Additionally, the patent describes a method for performing blood treatments using the system. It involves connecting different fluid circuits to the machine at different times for specific treatments, such as hemodialysis or hemofiltration. The method includes dilution of blood with various fluids like replacement fluid or anti-coagulant. The blood is pumped in parallel flow paths to a blood oxygenator, combining the split blood streams for treatment. The system's flexibility allows for a range of blood treatments and configurations, enhancing the efficiency and effectiveness of extracorporeal therapies.
