The application relates to the technical field of
kidney dialysis medical equipment, in particular to a
kidney dialysis blood multi-stage filtering device with optimized flow channels, which comprises a device body; three groups of filtering cylinders are driven in linkage by a
micro motor, a rotating shaft, a driving gear and a transmission gear ring, the driving gear and the transmission gear ring are sequentially reduced from top to bottom, the three groups of filtering cylinders rotate at different rotating speeds, the internal filtering units are driven to work efficiently, the filtering unit apertures are sequentially reduced from top to bottom, the filtering unit apertures are respectively set as pretreatment filtering units, precision filtering units and deep adsorption filtering units, a grading purification
system is formed, different molecular weight toxins can be targetedly removed, the linkage structure of a pawl, a
ratchet ring, a connecting rotating rod and a return spring can dynamically adjust the angle of the filtering units according to the changes of
blood flow and
pollution degree, the occurrence risk of low proteinemia of patients can be effectively reduced, the device can be flexibly adapted to the
disease differences of different patients, individualized precise treatment can be realized, and the
kidney dialysis treatment effect is improved.
