141 results about "Hemoperfusion" patented technology

Hemoperfusion or hæmoperfusion (see spelling differences) is a method of filtering the blood extracorporeally (that is, outside the body) to remove a toxin. As with other extracorporeal methods, such as hemodialysis (HD), hemofiltration (HF), and hemodiafiltration (HDF), the blood travels from the patient into a machine, gets filtered, and then travels back into the patient, typically by venovenous access (out of a vein and back into a vein).
