Tomsk Polytechnic University (TPU) has announced a cutting-edge development: local scientists have created a highly effective filter for donor blood.
Scientists at Tomsk Polytechnic University, commissioned by "Profit Pharm," have developed import-substituting membranes for mobile filters. Passing blood through such mobile filters is an alternative method of cleaning it. It is particularly relevant when an emergency blood transfusion is needed in "field" conditions. Blood purification can be carried out directly during its collection – the filtering device is attached to a venous catheter.
The main element of the filter is a membrane consisting of layered special composites with a microporous structure. As they pass through the membranes, leukocytes are retained due to the pore size and the electrical charge on the surface of the fibers. The membrane production technology is entirely domestic.
The membranes developed at TPU are 40% more effective than Japanese counterparts, which are a recognized standard. That is, with a smaller thickness and fewer layers, they filter blood with the same efficiency as imported products. This property of the membranes has a good effect on the filter's performance and its speed. The thinner the size of the filtering element, the more blood it passes.
With the new filters, blood can be purified in the field. The development has successfully passed tests at the Kirov Research Institute of Hematology and Blood Transfusion of the Federal Medical-Biological Agency of Russia.
