近日,日本科学家发明了一种可以吸收血液中的肌酸酐的纳米纤维网,这一发明有望用于研发出便携式的血液透析设备,帮助肾衰竭患者减轻痛苦。肾衰竭患者往往无法自行清除体内的代谢废物,而如钾、尿素、肌酸酐等物质积累到一定程度会十分危险。在这种情况下,除了移植一个健康的肾以外,最好的解决办法就是透析。然而透析,也实为无奈之举。这种方法耗费时间、还需要专业设备、干净的水、电力、透析液,并且通常只能在医院里进行。而对于发展中国家的农村地区以及灾区,这些要求经常得不到满足。透析法是利用分 Recently, Japanese scientists have invented a nano-fiber network that can absorb creatinine in the blood. The invention is expected to be used to develop a portable hemodialysis machine to help alleviate the pain of renal failure patients. Patients with renal failure often can not clear the body’s own metabolic waste, but as potassium, urea, creatinine and other substances accumulated to a certain extent will be very dangerous. In this case, the best solution other than transplanting a healthy kidneys is dialysis. However, dialysis, but also really helpless move. This method takes time, requires specialized equipment, clean water, electricity, dialysis fluid, and is usually only available in hospitals. These requirements are often not met in rural areas and in disaster-stricken areas in developing countries. Dialysis is the use of points
