Embodiment

[0034] see figure 1 , the portable blood purification system includes a high-flux dialyzer 4, the lumen inlet 401 of the high-flux dialyzer 4 communicates with one end of the arterial catheter 100, and the arterial catheter 100 is connected in series with an arterial valve 101 and an arterial pressure sensor 103 from the other end. and the blood pump 104; the lumen outlet 402 of the high-flux dialyzer 4 is connected to one end of the venous catheter 110, and from the other end, the venous valve 109, the venous temperature sensor 108, the venous bubble detector 107, and the venous catheter are sequentially connected in series. The pressure sensor 106 constitutes an extracorporeal circulation unit; the arterial pressure sensor 103 and the venous pressure sensor 106 are respectively equipped with bubble collectors;

[0035] The outer cavity inlet 403 of the high-throughput dialyzer 4 is connected to one end of the cleaning liquid pipe, and the other end of the cleaning liquid pip...

Abstract

The invention relates to a portable blood purifying system, which comprises a high throughput dialyzer with an arterial duct, a venous duct, a washing liquid tube and a transfusion tube; the arterial duct is in turn connected in series with an arterial valve, an arterial pressure sensor and a blood pump; the venous duct is in turn connected in series with a venous valve, a venous temperature sensor, a venous bubble detector and a venous pressure sensor, so that an external circulation unit is formed; the washing liquid tube is connected in series with a pre-charging valve and is communicated with a washing liquid container; the transfusion tube is in turn connected in series with a temperature controller, a transfusion tube bubble collector and a transfusion pump, and is communicated with a waste liquid container, so that a waste liquid processing unit is formed; and the system also comprises a transfusion pump, a temperature control device, a transfusion tube, a gating valve and a first transfusion branch and a second transfusion tube branch, so that a transfusion unit is formed. The system is simplified in structure and convenient to carry; and the system is suitable for patients to do short-time dialysis for several times or night dialysis treatment at home as household treatment equipment, so that toxin tolerance of dialysis patients during dialysis period is relieved while medical cost is reduced.

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...
