Abstract

The invention relates to a portable blood purification apparatus, a system comprising an osmotic apparatus having a main tube, an auxiliary tube, a washing tube and a flow guide tube. A driving valve, a driving pressure controller and a peristaltic pump are connected serially and sequentially to the main tube. A driven valve, a driven temperature controller, a gas measuring device and a driven pressure controller are connected serially and sequentially to the auxiliary tube. The washing tube is serially connected with a control valve and is communicated with a washing device. A temperature controller, a flow guide tube gas collector and a liquid outgoing pump are connected serially and sequentially to the flow guide tube that is communicated with a waste liquid container, forming a waste liquid treatment unit. The system further comprises a liquid outgoing pump, a temperature controller, a flow guide tube, a valve, a main flow guide tube branch and a second flow guide tube branch, forming an infusion unit. The portable blood purification apparatus is simple in structure and convenient to carry; as a household treatment apparatus, the system is suitable for a patient to use at home to take multiple short-term dialysis or night dialysis treatment, reducing medical cost and reducing toxin tolerance of the patient during dialysis.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical device for unconventional dialysis for treating acute and chronic renal failure, multiple organ failure, severe drug and poison poisoning, that is, a blood purification system. Background technique [0002] Renal failure and uremia are critical diseases that are very common all over the world. According to the American Kidney Database, there were more than 450,000 patients with end-stage renal failure in the United States in 2005. In my country, according to incomplete statistics from the Chinese Society of Nephrology, there are more than one million uremia patients in need of treatment. [0003] At present, the main method used in the treatment of renal failure and uremia is dialysis, including hemodialysis and peritoneal dialysis. Hemodialysis has the advantages of sufficient toxin removal and long-term application, and is the most widely used tr...
