Description

The plasmapheresis device extracorporeal circulation pipeline of changeable blood separator
Technical field
The present invention relates to a kind of medicine equipment, specifically a kind of apparatus for purifying blood body of changeable blood separator External circulation line.
Background technology
Artificial liver technology, i.e. artificial liver blood purification technology, are that one kind temporarily substitutes liver work(using blood purification technology Can, liver cell is recovered regeneration, and finally save the new medical technology of patients ' lives.In terms of technical standpoint, refer to blood plasma Displacement and Blood index technology, that is, dissolve inflammation-causing substance in blood or toxin is adsorbed to the solid with abundant surface area Used in matter and anti-inflammatory agent and poisonous substance are removed from blood.Artificial liver technology is used exclusively for blood toxin expelling.It uses and " changed The mode of blood " drains the toxin in patient plasma, is the blood plasma for the blood plasma that patient contains toxin being changed into health, each time About change the blood plasma of whole body 50% or so.
The extracorporeal circulation pipeline of existing artificial liver technology plasmapheresis device, including enter blood vessel road, blood pump, blood point The blood circulation system constituted from device, blood back pipeline, the waste liquid being made up of waste-solution line, blood plasma pump, waste liquid collection vessel is discharged System, by displacement liquid container, displacement liquid pipeline, displacement liquid pump group into displacement liquid replenishment system.Its operation principle is:By patient Blood draw external, the blood plasma of patient is separated from whole blood by membrane plasma separation method and discarded, is then supplemented The displacement liquid such as the fresh frozen plasma of equivalent or human blood protein, just can so remove various metabolic toxicities and the cause in patient's body Cause of disease, so as to reach the purpose for the treatment of.In can not only being removed in vivo due to plasma exchange, the metabolic toxicities of small molecule, The macromolecular substances such as albumen, immune complex are also removed, therefore the clearance rate of harmful substance is filtered more than haemodialysis, blood Cross, blood perfusion will get well, while preferably substituted supplemented with required materials such as albumin, the clotting factor lacked in vivo again Liver some functions.
Artificial liver technology relies on the extracorporeal circulation of blood path of unobstructed stabilization, before unobstructed circulation line is smoothly treated Carry, artificial liver technology VPV is in 80 ~ 120ml/min, when blood flow is excessively slow, anti-coagulants injection volume not enough, or due to patient Bleeding etc. can not be in particular cases used when anti-coagulants, it is easy to cause transmembrane pressure(TMP)Blood coagulation occurs in vitro to make Blocked into separator, cause plasma exchange not continue, cause artificial liver technology to fail.
