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

Embodiment 1

[0025] See attached figure 1 As shown, the embodiment of the present invention discloses a plasma exchange adsorption system, including: plasma separator 1, plasma collection pipeline 2, first blood pump 4, waste liquid bag 6, replacement liquid bottle / bag 7, first plasma Storage bottle / bag 8 and second plasma storage bottle / bag 9;

[0026] The output end of the plasma collection pipeline 2 is connected with the input end of the plasma separator 1, and the first electromagnetic valve 17 is connected on the plasma collection pipeline 2, and the output end of the plasma separator 1 passes through the pipeline and the waste liquid bag 6, replacement The liquid bottle / bag 7 , the first plasma storage bottle / bag 8 and the second plasma storage bottle / bag 9 are connected, and the first blood pump 4 is set on the plasma collection pipeline 2 .

[0027] In a specific embodiment, it also includes: a plasma adsorber group 3, the input end of the plasma adsorber group 3 is connected to ...

Embodiment 2

[0039] See attached figure 2 As shown, when the second solenoid valve is closed, the blood is replaced, the whole blood is collected from the human body, and the harmful components (such as: pathogenic factors, allergic factors, inflammatory factors, etc., or some components deviate from the normal Value, toxic components) plasma, stored in the waste plasma bag, the prepared replacement fluid (you can choose colloid, crystal liquid), such as: replacement plasma, plasma, saline, etc. It is transfused into the human body from another channel. In the fully automatic mode, the replacement fluid is first transferred to the centrifuge cup, mixed with the original blood cells and then transfused into the human body; in the semi-automatic or manual mode, the substitution fluid is directly transfused into the human body.

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 ...
