Description

Clinical continuous blood component centrifugal separator
Technical Field
The utility model relates to the field of medical equipment, concretely relates to be used for clinical continuous type blood composition centrifuge.
Background
The blood purification therapy is a clinical treatment technology developed by technologies such as hemodialysis and exsanguination, is rapidly developed in the late twentieth century, and becomes an indispensable treatment method in clinical practice.
A blood purification system generally comprises an extracorporeal circuit, which comprises a blood outflow circuit and a blood return circuit, and a blood purification device connected to the extracorporeal circuit. In the process of blood purification treatment, blood is led out of a human body through the blood outflow pipeline, purified by the blood purification device and then returned to the human body through the blood backflow pipeline, so that substances such as pathogenic factors in the blood are removed.
The core technology in blood purification therapy is the separation of blood components, and currently, the mainstream separation technologies include a centrifugal separation technology, a membrane separation technology, and an adsorption separation technology.

The membrane separation technology has the advantages of high separation efficiency, easy adjustment of electrolyte balance and the like. However, the membrane separation technology has the disadvantages of relative specificity, and cannot give consideration to target substances with different molecular weights and different hydrophilic and hydrophobic properties, and repeated treatment is required, so that the treatment cost is increased, and the tolerance of patients is also reduced sharply.
The adsorption separation technology is that the adsorbent is filled in an adsorber to make a disposable sterile medical apparatus, then the blood is led out from the human body and passes through an adsorption column in a blood perfusion or plasma perfusion mode to specifically or relatively specifically adsorb one or more pathogenic substances, and the commonly used adsorber comprises a disposable hemoperfusion device, a disposable endotoxin adsorber, a disposable plasma bilirubin adsorber, a DNA immunoadsorption column, a blood fat adsorption column, a leukocyte adsorption column and the like.

Therefore, it has been an important research direction in the field to combine the advantages of centrifugal separation, membrane separation and adsorption separation techniques and to comprehensively utilize the advantages of the three.
There is currently no continuous clinical blood component centrifuge available on the market for centrifugal separation technology. Can separate specific components of blood, thus being capable of carrying out advanced blood component treatment technologies such as plasmapheresis, erythrocyte removal, leukopenia, thrombopenia, blood fat removal, artificial liver treatment and the like.
