Resin intelligent purification system for hemoperfusion device

Abstract

The invention discloses a resin intelligent purification system for a hemoperfusion device.The resin intelligent purification system comprises a perfusion device shell, the upper end and the lower end of the perfusion device shell are detachably connected with an upper cover and a lower cover respectively, a connecting shaft is arranged inside the perfusion device shell, the upper end of the connecting shaft is connected with the upper cover, the connecting shaft rotates relative to the perfusion device shell, a plurality of movable resin discs are fixedly arranged on the periphery of the connecting shaft, a plurality of fixed resin discs are fixedly arranged on the inner wall of the perfusion device shell, the movable resin discs and the fixed resin discs are arranged at intervals in the vertical direction, a plurality of resin adsorption areas are evenly arranged on the movable resin discs and the fixed resin discs at intervals, and a resin adsorption plate is fixedly arranged at the bottom end inside the perfusion device shell. Through the arrangement that a connecting sleeve in the upper cover and a movable cover can rotate relatively, relative angles between the movable resin discs and the fixed resin discs can be adjusted according to the concentration of harmful substances in blood, the adsorption time is reasonably shortened, the adsorption quality is guaranteed, and the adsorption efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an intelligent resin purification system for hemoperfusion devices. Background technique [0002] Hemoperfusion device is mainly used in the adsorption of acute and chronic drug poisoning, molecular toxins in uremia, and pathogenic factors in the field of liver disease and immunity. Patients with advanced renal failure need to rely on dialysis to maintain their lives. The small molecular substances in the blood can be effectively removed through the dialysis membrane. Key substances that affect the health of patients, and these middle-molecular-weight substances are difficult to effectively remove by dialysis; in terms of maintaining the life of patients with renal failure, whether hemodialysis or hemoperfusion is used, the effective removal of middle-molecular substances has become a measure of whether the treatment is effective. new judging criteria.
