Membrane-free dialysis micro-fluidic chip with parallel structure

Abstract

The invention discloses a membrane-free dialysis micro-fluidic chip with a parallel structure, which comprises a plurality of dialysis assemblies, the dialysis assemblies are arranged in parallel, and the dialysis assemblies alternately form a cleaning section and a separation section along the blood flowing direction; the dialysis assembly comprises a blood channel and a dialysate channel, and the blood channel and the dialysate channel meet in the cleaning section and are separated in the separation section; in the cleaning section, blood and dialysate make contact in the center of a cleaning section channel, and when the blood and the dialysate enter the next cleaning section, the contact face of the blood and the dialysate is the outer side fluid of the previous cleaning section. According to the membrane-free dialysis micro-fluidic chip, the problems of low efficiency and large cell loss of existing dialysis are solved, the dialysis efficiency is effectively improved, the loss of blood cells is reduced, the parallel honeycomb network structure of the membrane-free dialysis micro-fluidic chip is utilized, the purposes of improving the working capacity of the chip and reducing the volume of an artificial kidney are achieved, and the utilization efficiency of dialysate is improved.

Description

technical field [0001] The invention relates to a membraneless dialysis microfluidic chip with a parallel structure. Background technique [0002] At present, there are nearly 800,000 dialysis patients in my country. With the acceleration of aging in my country, the continuous improvement of dialysis quality and dialysis treatment rate, and the improvement and improvement of medical insurance, the number of dialysis patients continues to increase at a rate of about 10% per year. The number of patients requiring dialysis treatment will exceed 3 million by 2030. Dialysis is one of the effective measures to prolong the life of patients and improve the quality of life of advanced patients. Hemodialysis machine, commonly known as "artificial kidney", is an extracorporeal hemodialysis device that can replace part of the kidney function, remove harmful substances in the blood, correct electrolytes in the body and maintain acid-base balance. [0003] Most of the existing dialysis d...
