血液净化方法1.血液透析(Hemodialysis.HD)HD包括溶质和水的清除.溶质从高浓度向低浓度侧运动,称弥散;液体在压力梯度作用下通过半透膜的移动,称超滤.HD是将病人血液与含一定化学成纷的透析液同时引入透析器膜的内、外室,溶质通过半透膜作跨膜移动(见图1).通过HD,病人体内的代谢废物得以清除,纠正了电解质和酸碱失衡状态,并排除多余的水份.所以血液透析可部分地替代肾脏功能,是目前应用最广泛的血液净化方法之一.2.血液滤过(Hemofiltration.HF)
Blood purification methods 1. Hemodialysis (HD) HD includes the removal of solutes and water, solutes move from high to low concentrations, and disperse; the liquid moves through the semi-permeable membrane under the pressure gradient and is called ultrafiltration. HD is the patient’s blood and a certain chemical-containing dialysate at the same time into the dialyzer membrane inside and outside the chamber, solute transmembrane transmembrane movement (see Figure 1) by HD, the body’s metabolic waste to be cleared , To correct the electrolyte and acid-base imbalance, and remove excess water.Therefore, hemodialysis can partially replace renal function, is currently one of the most widely used methods of blood purification.2 Hemofiltration (HF)
