Plasma exchanging, dialysis and adsorption system

Abstract

The invention discloses a plasma exchanging, dialysis and adsorption system. The system comprises a plasma separator, a blood feedback pipe and a plasma separation pipe, wherein the plasma feedback pipe is used for transporting blood which is separated by the plasma separator back to the human body, and the plasma separation pipe is used for exporting plasma which is separated by the plasma separator; the plasma exchanging, dialysis and adsorption system further comprises a plasma discharging pipe, a plasma dialysis and adsorption pipe, a liquid supplement pipe and a plasma feedback pipe whichis used for transporting back fresh plasma or the plasma which is subjected to dialysis and adsorption treatment, the input end of the plasma dialysis and adsorption pipe is connected with the outputend of the plasma separation pipe and the input end of the plasma discharging pipe, the input end of the plasma feedback pipe is connected with the output end of the plasma dialysis and adsorption pipe and the output end of the liquid supplement pipe, and the output end of the plasma feedback pipe is connected with the blood feedback pipe. The plasma exchanging, dialysis and adsorption system hasthe advantages that the system is simple in structure and convenient to use, avoids complex equipment transformation and can sufficiently develop the treatment advantages of various blood purifying techniques.

Description

technical field [0001] The invention relates to a medical instrument for blood purification, in particular to a plasma exchange dialysis adsorption system, which is especially suitable for patients with liver failure and multiple organ failure. Background technique [0002] There are a large number of inflammatory mediators in patients with liver failure and multiple organ failure, which can be divided into protein-bound toxins and water-soluble toxins according to their physical and chemical properties. Modern artificial liver technology requires comprehensive removal of protein-bound toxins and water-soluble toxins, and supplementation of albumin and coagulation factors that are insufficiently synthesized by the liver. At present, artificial liver replacement therapy and blood purification technology for multiple organ failure are developing rapidly. The most common artificial liver model is the rational application and integration of four basic blood purification technolo...

Problems solved by technology

[0005] Chinese patent document CN203280813U discloses a plasma exchange adsorption filtration purification system equipped with a plasma storage bag. The system combines plasma exchange, plasma adsorption and plasma dialysis. First, plasma exchange is performed for 1 hour, followed by 5 hours of plasma exchange sequentially. Adsorption and plasma dialysis, but its composition is complicated, and it needs a special purification device with 6 pumps or two ordinary blood purification devices to work at the same time, and its clinical application is limited.

At present, most of the blood purification instruments approved for use at home and abroad are four single-tube pumps. Due to the difficulty of equipment modification and high cost, its applicability is limited.
