Adsorption, filtration and purification system for plasma exchange treatment

Abstract

The invention relates to the technical field of plasma exchange, in particular to an adsorption, filtration and purification system for plasma exchange treatment, which is characterized in that a liquid inlet of a first-stage plasma separator is connected with a first conveying pipeline, and a first liquid outlet of the first-stage plasma separator is connected with a liquid inlet of a second-stage plasma separator through a second conveying pipeline; a first liquid outlet of the plasma secondary separator is connected with a liquid inlet of the plasma adsorber through a third conveying pipeline; the primary plasma separator separates blood into blood cells and plasma, the plasma enters the secondary plasma separator to be divided into plasma containing pathogenic factors and plasma without pathogenic factors, the plasma containing the pathogenic factors enters the plasma adsorber and the blood filter, and the plasma is adsorbed by the plasma adsorber and filtered and purified by the blood filter to obtain purified plasma; the adsorption, filtration and purification system for plasma exchange treatment completes separation of blood, purification of plasma containing pathogenic factors and collection of blood cells, plasma without pathogenic factors and purified plasma.

Description

technical field [0001] The invention relates to the technical field of plasma exchange, in particular to an adsorption filtration purification system for plasma exchange treatment. Background technique [0002] Plasma exchange is a special extracorporeal blood purification technology, which uses a plasma separator or centrifugation to separate the patient's plasma from blood cells, discards the plasma containing pathogenic substances, and replenishes the same amount of replacement fluid at the same time, so as to achieve the treatment of diseases the goal of. Plasma exchange can remove pathogenic factors faster and more effectively than drug treatment, creating powerful conditions for the treatment of primary diseases. [0003] The double plasma exchange in plasma exchange purifies the separated plasma containing pathogenic factors, and then returns the purified plasma and the formed components of blood back to the body after discarding the pathogenic factors. [0004] The...
