Plasma exchange and adsorption system

Abstract

The invention discloses a plasma exchange and adsorption system. The system comprises a plasma separator, a plasma collection pipeline, a first blood pump, a waste liquid bag, an exchange liquid bottle / bag, a first plasma storage bottle / bag, and a second plasma storage bottle / bag; and the output end of the plasma collection pipeline is connected to the input end of the plasma separator, the outputend of the plasma separator is connected to the waste liquid bag, the exchange liquid bottle / bag, the first plasma storage bottle / bag and the second plasma storage bottle / bag through a pipeline, andthe first blood pump is arranged on the plasma collection pipeline. According to the system, plasma exchange, plasma adsorption and plasma dialysis are combined, the therapeutic advantages of variousplasma purification technologies can be fully exerted, and requirements of current plasma purification equipment can be met.

Description

technical field [0001] The invention relates to the technical field of plasma purification equipment, in particular to a plasma exchange adsorption system. Background technique [0002] At present, plasma exchange is to extract the patient's plasma, separate the plasma and cell components through a plasma exchange device, and discard some pathogenic substances, metabolites, and autoantibodies and toxins of some autoimmune diseases in the plasma, and the cells The ingredients and the same amount of plasma substitutes are transfused back into the body to remove the pathogenic and harmful factors in the body. Plasma exchange can quickly eliminate harmful substances in the body, improve the body's functional status and immune regulation, and restore organ functions. It is a quick and effective auxiliary treatment. [0003] However, the discarded plasma of traditional plasma exchange contains many useful parts. At the same time, the replaced plasma or frozen plasma has allergic ...

Problems solved by technology

[0003] However, the discarded plasma of traditional plasma exchange contains many useful parts. At the same time, the replaced plasma or frozen plasma has allergic reactions to patients, and a large number of beneficial components cannot be effectively reinfused. There are two kinds of filtration methods: membrane filtration and centrifugation. Membrane filtration mainly uses membranes to separate plasma and then adsorb or directly use whole blood to absorb. There will be cases where the membrane cannot be normally treated due to blood viscosity; for example, the document number is CN204543040U The Chinese patent document discloses a plasma replacement system, although a certain blood replacement function is realized, but the alarm function cannot be realized when air enters; The replacement pipeline, replacement and adsorption plasma confluence pipeline requires 4 pumps to complete slow plasma replacement and plasma adsorption simultaneously, and its structure and pipeline design are relatively complicated
