SORPTION COLUMN FOR CLEANING BIOLOGICAL LIQUIDS Russian patent published in 2003 - IPC

FIELD: medical equipment. SUBSTANCE: sorption column has cylindrical casing and two similar slit-type perfusion devices positioned at casing ends. Perfusion device is fixed in hermetically sealing relation in column casing and is composed of enclosure and internal part arranged in spaced relation with one another so as to define gap for perfusion of biological liquid between them, and fixing coupling. Internal part is made in the form of union provided with head and threaded part passing through opening in enclosure of perfusion device for connection with fixing coupling. Union head defines slit with perfusion device enclosure and is made cylindrical (in case enclosure is made cylindrical). Union is provided with internal liquid passage channels: axial channel passing through head and threaded portion, and several channels diverging from axial channel in union head for connecting axial channel with slit. Sorption column is used for cleaning biological liquids such as blood, plasma, lymph, liquor from toxins, and allows sterilization procedure to be effected in assembled state, i.e., with sorbent inside thereof. Such construction allows risk of infecting patient to be substantially reduced. EFFECT: increased useful volume of column, provision for performing perfusion of biological liquid in any direction and adequate kinetics of perfusion. 5 dwg
