Scientists develop filter to save patients with blood poisoning

Residents of the Science Park of Moscow State University (Russia) have introduced a new tool to combat sepsis - blood poisoning and it has already been approved for the use in clinical practice.

According to Russian medie, mortality in sepsis, according to statistics, is more than 30%. A special filter for blood, developed by scientists, can make a difference.

It works as follows: blood is pumped through an apparatus with a filter element made of a polymer that collects harmful substances. The main objective of the filter is to retain the bacterial lipopolysaccharide associated with sepsis. Thus, pure blood returns to the patient’s body.

This is a plastic cylindrical body filled with sorbent. It has standard “ports” for “connecting” human vessels. Using a special pump, the patient’s blood is passed through a sorbent under slight pressure. Blood cells and large plasma proteins pass through it, and lipopolysaccharides (toxins) do not pass. Thus, purified blood returns back to the circulatory system, and toxic substances firmly bound to the sorbent are removed from the body, said Ivan Bessonov, the inventor of the sorbent.
