Blood purification system portable alternative to dialysis.

The 19th , Ebara senior researcher from the same mechanism bio- functional materials unit has developed a blood purification system portable alternative to dialysis which is indispensable in patients with chronic renal failure for Materials Research Organization ( Tsukuba, Ibaraki ) announced . Good first aid to the dialysis patient is made ​​possible in the event of a disaster , I aim to commercialize six years later .
Was developed , blood purification system using a wristwatch-type compact cartridge that runs on two AA batteries . The adsorption newly developed material which is attached to the cartridge , one of the uremic toxins that renal failure patient is removed by dialysis to " creatinine " and " high-performance nano- fiber mesh " will be removed from the blood .
The weaving mineral that adsorption of the "zeolite " , to remove the only creatinine in the new material . In 16 g of new materials , we succeeded in removing about 50 mg creatinine to accumulate in 1 hour . And by applying the principle of purification cartridge attached to the faucet , that it replace the new material in the cartridge , that it is also possible removal of creatinine for one day , which is discharged into the body .
Ebara chief scientist has said, " life line is disrupted by the disaster , it is possible to cover the burden of dialysis patients , such as emergency visits can be difficult " he said. It is technology that is required in the disaster what time it might happen . Please complete further research and development towards the early realization .



物質・材料研究機構（茨城県つくば市）は１９日、慢性腎不全患者に欠かせない人工透析に代わる携帯型の血液浄化システムを、同機構生体機能材料ユニットの荏原主任研究員らが開発したと発表した。災害時に透析患者への応急処置が可能となるといい、６年後の実用化を目指す。
　開発したのは、単３電池２本で稼動するコンパクトな腕時計型カートリッジを使った血液浄化システム。腎不全患者が人工透析で除去している尿毒素の一つ「クレアチニン」を、カートリッジ内に取り付けた新開発素材「高性能ナノファイバーメッシュ」で吸着し、血液中から除去する。
　新素材には吸着性のある鉱物「ゼオライト」を織り込み、クレアチニンだけを取り除く。新素材１６グラムで、１時間で蓄積するクレアチニン約５０ミリグラムを除去することに成功した。水道の蛇口に付ける浄化カートリッジの原理を応用しており、カートリッジ内の新素材を取り換えることで、体内に排出される１日分のクレアチニンの除去も可能だという。
　荏原主任研究員は「災害でライフラインが寸断され、通院が困難な緊急時などに透析患者の負担をカバーできる」と話している。何時起こるかもしれない災害時においては必要になる技術ですね。早期の実用化に向けて更なる研究開発を進めてください。
