摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment. Filter for collection of biological material in endovitral operations consists of a hollow cylindrical body with a lid and flanged membrane. Body has the outer diameter of 2 cm and height of 5 cm. One of the ends of the body is made dull, on the side surface of the body adjacent to the other end, an external screw thread is made for connection to the internal thread of the lid. Inside the body, at a distance of 2 mm from the cover, an annular shaped protrusion is formed integrally with the body to form an annular groove between the lid and the protrusion to accommodate the flanging of the cylindrical membrane therein. Internal diameter of the protrusion is equal to the membrane diameter, its thickness is 2 mm. Membrane is made of polyethylene terephthalate with a pore size of 50 mcm. In the body lid and on the opposite cover, the blind end is formed as a single unit with them along a hollow cylindrical tube of the same size, coaxial to the body and the membrane. Body, lid, protrusion and tubes are made of polypropylene.EFFECT: technical result consists in ensuring the sampling of biological material in endovitral operations in the form of different portions, regardless of its composition and quantity, and convenient and rapid extraction of the membrane from a biological material from the filter and sent to study.1 cl, 3 dwgИзобретение относится к медицинской технике. Фильтр для сбора биологического материала при эндовитреальных операциях состоит из полого цилиндрического корпуса с крышкой и мембраны с отбортовкой. Корпус имеет наружный диаметр 2 см и высоту 5 см. Один из торцов корпуса выполнен глухим, на боковой поверхности корпуса, примыкающего к другому торцу, выполнена наружная винтовая резьба для соединения с внутренней резьбой крышки. Внутри корпуса на расстоянии 2 мм от крышки выполнен выступ кольцевой формы как единое целое с корпусом с образованием кольцевого паза между крышкой и выступом д
