Description
Technical field
This utility model relates to a kind of armarium, in particular for removing the medical artifical system for supporting liver and kidney of intravital exogenous and endogenous poisonous substance, refuse or other harmful substance of liver renal failure patient.
Background technology
Liver renal failure is a modal mode among the multiple organ failure, MOF, and toxic substance is more in the liver renal failure blood samples of patients, and existing and albumin bound material (as bilirubin) has the medium and small molecule toxin of a large amount of water solublity again.Common blood purification method and toxin reset mode are more single, below make introductions all round:
Hemodialysis---utilize disperse and ultrafiltration principle that patient's blood, dialysis solution are introduced in the dialyser (artificial kidney) simultaneously.Blood and dialysis solution are reverse flow in the inside and outside both sides of dialyzer, solute concentration gradient, osmotic gradient and hydraulic pressure gradient by means of both sides inside and outside the film, reach the both sides concentration balance by dispersion, to remove human body intracellular metabolic refuse, the material that needs be can replenish simultaneously, electrolyte and acid base imbalance corrected.Hemodialysis can be removed intravital soluble small molecular toxin of liver renal failure patient (as flesh liver, the blood urea nitrogen that renal failure produces, the blood ammonia that liver failure produces etc.) and excessive moisture, but almost can not remove albumin bound toxin and middle macromole toxin.
Hemofiltration---be the filtering function of imitation human body glomerule, utilize barometric gradient, a kind of blood purification method that poisonous and harmful substance in the blood is excreted by the filter semipermeable membrane, hemofiltration can be removed the medium and small molecule toxin that liver renal failure produces, but a little less than the removing of dialogue protein binding toxin.
Hemoperfusion---utilize the absorption principle of strong adsorbent such as active carbon or resin, the blood lead body is directly contacted with adsorbent outward, more measure solute in the absorption blood, remove endogenous or exogenous poisonous substance in the blood, reach the purpose of blood purification, hemoperfusion is mainly removed the fat-soluble macromole toxin that liver renal failure produces, and micromolecule can not effectively be removed in the water solublity.
Plasmapheresis---be to utilize plasma separator that the plasma fraction in the blood is separated to abandon, mend fresh plasma simultaneously in addition, toxin in the blood is followed blood plasma to abandon and is removed, it is better that plasmapheresis is removed effect to the macromole toxin, but it is relatively poor that micromolecule in the water solublity is removed effect, imports outside fresh plasma so increased the treatment cost and brought out complication easily because of needs.
The albumin adsorption cleaning---adopt and transport albumin bound toxins in the blood at the film outer circulation albumin solution of filter, the outer albumin solution of film is removed bonded toxin through adsorber again, albumin solution after the purification repeats next circulation again, the albumin adsorption cleaning is mainly removed albumin bound toxin (as bilirubin a large amount of in the blood of human body in the liver failure etc.) and soluble small molecular toxin, limited in one's ability to the middle molecule toxins removing, and the albumin of outer loop has also increased the treatment cost.
The blood cleaning equipment treatment pattern that is used for the treatment of at present liver renal failure both at home and abroad is more single, often can only carry out independent liver failure Supporting Therapy or renal failure Supporting Therapy, and it is not thorough that they remove toxin.And the toxin of wanting to remove simultaneously liver renal failure often need clinically multiple devices simultaneously (or successively) carry out, inconvenient operation, the treatment cost is too high, and delays best occasion for the treatment easily because treatment time prolongs.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of artifical system for supporting liver and kidney that can remove interior a large amount of medium and small molecule toxins of water solublity of liver renal failure patient body and albumin bound toxin simultaneously.
