    The invention relates to medical chemistry, a filter and a method for removing red blood cells from the blood. The purpose of the invention is to increase the degree of red blood cell removal. For this, a filter is used as follows. Blood is applied to the upper side of layer 1 of man-made fibers, fixed with mesh 5. Red blood cells and white blood cells are separated in the layer from the plasma passing through layer 4 and entering the reaction layer 2 or collection. Plasma collection is stopped when the maximum flowing volume reaches 50% of the adsorption layer, after which the layer of artificial fibers together with the grid 5 is separated by means of the fixed part 4a of the grid. The reaction layer is ready for further work with it. Glass fibers, with a diameter of 0.2-2.5 µm and packing density of 0.1-0.5 g / cm, are used as artificial fibers. 2 sec. f-ly, 1 ill. ABOUT)

    The invention relates to medicine, in particular to the field of medical chemistry and concerns a filter and a method for removing red blood cells from the blood.
    The aim of the invention is to increase the degree of red blood cell removal,
    The drawing shows a filter for implementing a method for removing red blood cells from blood.
    Layer 1 of man-made fibers, which used glass fiber with an average diameter of 0.2 to 2.5 μm and a packing density of 0.1 to 0.5 g / cm, is placed on top of the reaction layer 2 located on a rigid base 3 , and separated from the layer 2 by a thin form-resistant and liquid-permeable layer 4, which is a net of woven or piled plastic threads. The loose portion of this mesh 4a is intended to remove layers 1 and 4 after the separation of red blood cells and white blood cells from blood. Layer 1 is also fixed over the top of grid 3.
    The reaction layer 2 can be made in the form of a suction carrier or porous polymer film. The base 3 can be made of a thicker polymer film, rigid cardboard, glass, etc.
    The filter works as follows
    Blood is applied to the upper side of layer 1, fixed with a mesh 5. Red blood cells, as well as white blood cells, are separated in layer 1 from the plasma that passes
    through layer 4 and enters the reaction layer 2 or collection. Plasma collection is stopped after the maximum outflow volume reaches 50% of the adsorption layer, after which layer 1 is separated with mesh 5 by means of the loose part of mesh 4a. Reaction layer 2 is ready for further work with it.
    A filter for removing erythrocytes from the blood, characterized by scrubbed glass fiber diameter and packing density, makes it possible to increase the degree of separation of erythrocytes from plasma and virtually eliminate the passage of red blood cells through the filtering layer.
