Abstract

The invention discloses a plasma circulation acceleration purifying system. The plasma circulation acceleration purifying system comprises a plasma circulation variable-speed bag and a plasma high-speed purifying device, wherein the plasma circulation variable-speed bag is provided with a low-speed plasma inlet, a low-speed plasma outlet, a high-speed plasma outlet and a high-speed plasma inlet; the high-speed plasma outlet is communicated with the high-speed plasma inlet through the plasma high-speed purifying device. The plasma circulation acceleration purifying system has the advantages that the contradiction of speed difference of plasma separation and plasma adsorption dialysis is solved, the structure is simple, and the functions are complete.

Description

technical field [0001] The invention relates to plasma circulation purification technology, in particular to a plasma circulation acceleration purification system. Background technique [0002] The blood purification technology of artificial liver replacement therapy has developed rapidly. At present, plasma exchange, plasma adsorption, hemofiltration, and albumin dialysis adsorption are the main forms of blood purification technology, which are effective and have their own characteristics. At present, domestic artificial liver is mainly based on plasma exchange, which can be divided into membrane plasma exchange and centrifugal plasma exchange according to different plasma separation methods. It can remove protein-bound toxins, supplement albumin and coagulation factors, but has limited ability to remove water-soluble toxins. Clinical use is limited by insufficient plasma supply, and there is a risk of inducing hepatic coma in patients with severe liver failure. At presen...
