Abstract

The invention discloses a blood purification system. The blood purification system comprises an arterial tube, a venous tube and a dialyzer, wherein one end of the arterial tube is an arterial connecting end, and the other end of the arterial tube is a dialyzer connecting end A; a flushing branch tube, a blood pump and an arterial pot are sequentially arranged between the arterial connecting end and the dialyzer connecting end A; one end of the venous tube is a venous connecting end, and the other end of the venous tube is a dialyzer connecting end B; a venous pot is arranged between the venous connecting end and the dialyzer connecting end B; the dialyzer comprises a shell; a second flow dividing plate is arranged at the bottom end of the interior of the shell; a second flow dividing cavity is formed in the second flow dividing plate; a dialysis membrane is connected to the top of the second flow dividing cavity; a first flow dividing plate is connected to the top of the dialysis membrane; a first flow dividing cavity is formed in the first flow dividing plate; and flow dividing holes are formed in one side of the first flow dividing cavity and one side of the second flow dividingcavity. The hemodialysis efficiency can be improved, and efficient operation of the blood purification system is facilitated.

Description

technical field [0001] The invention relates to the medical field, in particular to a blood purification system. Background technique [0002] Blood purification (also known as hemodialysis) is one of the most effective measures to treat acute and chronic renal failure and drug and food poisoning, and it is also the most commonly used method in clinical renal replacement therapy. The principle of blood purification is: the arterial extracorporeal circulation line leads the patient's blood out of the body, the dialyzer purifies the blood, and the venous extracorporeal circulation line returns the treated blood back to the patient. [0003] In the prior art, a blood purification system generally includes an arterial tube, a venous tube, and a dialyzer. One end of the arterial tube is an arterial connection end, and the other end is a dialyzer connection end A. The arterial connection end is connected to a human artery, and the dialyzer connection end A is Connected to the dia...
