This was a surprise, worked for Ebola maybe it would pull Coronaviruses out too!
Hemopurifier made of
protein mesh material attaches to a dialysis machine - The specially designed filter is made of a protein that acts as glue for proteins found on the Ebola virus surface. Over a period of 6.5 hours, the filter extracted the virus from the blood that flows through. While most dialysis filters can pull out molecules that are less than 4 nanometers in diameter, the virus filter boasts a mesh that’s able to filter out larger viral particles that are less than 250 nanometers. That means only the virus is pulled out, and the immune cells remain in the blood, ready to fight off any remaining viral invaders.

didn’t involve drugs. Aethlon Medical, a California-based company, was testing a way to quite literally filter viruses out of the blood of infected patients. The team had been testing their device, which attached to standard kidney dialysis machines, on hepatitis C and HIV patients in India. The German doctors, desperate to help their patient, asked to test it for Ebola.
“We had no [idea] about how much [virus] would be extracted, because this was the first patient, but I was very surprised because the drop in viral load was deeper than I expected,” says Geiger. Before the filtration began,
the patient’s virus count was about 400,000 per mL blood. After the session it had dropped to 1,000 copies/mL.What’s more, when Geiger’s team sent the filter, which was designed to safely contain the Ebola virus it had extracted, to the University of Marburg, which has a biosafety level 4 laboratory for safely handling the virus, they learned that the device had managed to trap 242 million copies of the virus.
Freed from that viral burden, the patient soon began to improve rapidly. His own immune system began fighting off the remaining virus, and he no longer needs dialysis or a ventilator.
The patient is walking and waiting to be released from the hospital.Geiger stresses that it’s not clear yet whether the Hemopurifier alone was responsible for the patient’s recovery, since he was given other experimental therapies, but the amount of virus removed from his body and his rapid recovery after the filtration suggests that it at least played a role in helping him survive his infection.
While puling viruses out of infected individuals has never been tried before, Geiger believes it will be an important strategy for treating
not just Ebola but other viral infections as well, including HIV, hepatitis and even influenza. “It’s a very interesting concept. The big advantage is that the plasma is filtered, and only the virus is removed and the other plasma components like immune cells go back to the patient. That’s important because with viral infections, the patient is in a reduced immune situation.”
The device works with most standard kidney dialysis machines, so Geiger says most hospitals would have no problem using it. And his team have worked out the mechanics of setting the blood flow to the proper levels to ensure the filter works at its best. “We have all the data that could be applied at other centers and for other users of the device,” he says.
