FIELD: medicine.SUBSTANCE: invention refers to medical equipment and aims at removal of toxic substances from biological fluids such as whole blood, blood plasma flowing through a patient's extracorporeal circulation system. A device includes a body, a cover, extracorporeal circulation line connectors with protective caps, filters and sorption vehicle arranged inside the body. The body has a bottom. The extracorporeal circulation line connectors are integrated with the bottom of the body and the cover, and accommodate a flare fitting and a coaxial outer nut with an internal thread. The body is coupled with the cover by mating surfaces coaxially formed on the inside of the cover by thin-walled annular projections and the body walls clamped in between. The mating surface of one of the annular projections of the cover has an annular groove detachably coupled with the annular projection on the body surface. The height of the projection of the body wall exceeds the depth of the groove of the cover.EFFECT: invention provides a simple technology, improved reliability and efficiency by reducing the number of parts and their compounds, and the use of a simple and safe method to join the parts without welds and toxic glues.3 cl, 3 dwg |
