Abstract

The invention discloses a micro-flow control chip for membrane-free dialysis. The chip comprises a blood inlet, a dialysate inlet, a straight working flow channel, reflection columns, an arc-shaped working flow channel, a chip shell, a blood outlet and a dialysate outlet, the blood inlet, the dialysate inlet, the straight working flow channel, the reflection column, the arc-shaped working flow channel, the blood outlet and the dialysate outlet are all mounted in the chip shell; the blood inlet and the dialysate inlet are symmetrically formed in an inlet of the straight working flow channel; the blood outlet and the dialysate outlet are symmetrically formed in an outlet of the straight working flow channel; the straight working flow channel is tangentially connected with the arc-shaped working flow channel; and the reflection columns are respectively arranged in the straight working flow channel and the arc-shaped working flow channel. According to the technical scheme, the problems that an existing dialysis membrane is low in efficiency and pollutes blood are solved, and cell loss in membrane-free dialysis is effectively reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of membraneless dialysis, and in particular to a microfluidic control chip for membraneless dialysis. Background technique [0002] At present, there are nearly 800,000 dialysis patients in my country. With the acceleration of my country's aging process, the continuous improvement of dialysis quality and dialysis treatment rate, and the improvement and perfection of medical insurance, the number of dialysis patients continues to grow at a rate of about 10% per year. It is estimated that in In 2030, the number of patients requiring dialysis treatment will exceed 3 million. Dialysis is one of the effective measures to prolong the life of patients and improve the quality of life of terminal 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, ...
