Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of for the novel of the diseases such as acute and chronic liver failure
Liver function supports system, i.e., a kind of regeneration and recycling that a variety of adsorbents can be achieved increases blood purification system Dusuqing
The type removed maintains cylinder electrolyte balance, eliminates human body oedema, improve the good biocompatibility of blood depuration efficiency, can have
Effect prevents medical albumin and adsorbent enter human body novel and multifunctional regeneration blood purification system design.
Background technology
Liver failure has become the critical illness for threatening the health of our people, and inducement mainly has immune injury, virus
Invasion, drug abuse and chronic alcoholism etc..Liver transfer operation is current treatment hepatic failure most effective way, but due to liver source is deficient,
Matching is difficult, the waiting donor time is very long and medical expense is expensive and limits its clinical practice, therefore there is an urgent need to liver function branch
Hold the development of system Medical Devices.Multifunctional recycled blood purification system（ALSS）It, can be temporarily as a kind of liver function replacement device
When assist lesion liver（Remove multiple harmful substances, execution part metabolic function）, until self liver function restore or into
Row liver transplant, so one of the effective ways as hepatic failure treatment.Multifunctional recycled blood purification system is typically based on blood
Starch the technologies such as displacement, haemodialysis, blood filtration, plasma dialysis filtering, blood perfusion, albumin dialysis, absorption removal blood
Middle toxin.Currently, multifunctional recycled blood purification system mainly has single cycle albumin dialysis system（SPAD）, Molecular Adsorption again
The circulatory system（MARS）And Prometheus（Prometheus）Deng.These systems can remove not soluble in water and protein knot
The toxin of conjunction, but all there are it is respective the problem of, such as：The elimination efficiency of MARS system toxin not only sorbent suspension dosage and type
Influence, while also limited by tunica fibrosa mass-transfer efficiency；The albumin loss of Prometheus systems human body itself is big；
SPAD systems need to cause treatment cost high with a large amount of human albumins.
The basic principle of liver system be by a device temporarily or completely substitute serious change hepatic portion or
Repertoire, mainly remove patient's body due to liver function lose and accumulate promote liver organization that can not regenerate, firmly
Change with the metabolin toxin of carcinogenesis.Currently, generally use dialysis removes water-soluble metabolin toxin, using absorption side
Formula removal is not soluble in water, metabolin toxin with albumin combination.But unreasonable design may lead to itself albumin
Loss, adsorbent particles enter human body, adsorbent utilization rate are low, itself albumin is polluted by external albumin etc., so as to cause
Not only liver system price is expensive, but also toxin elimination efficiency can be caused low and safety risks.
