一、概述人工肾透析装置中用的泵与其他工业设备所用的泵有着以下绝然不同的特殊要求: 1.因泵与人体血液间接接触,为此要求泵体中的零件不能带有任何损害人体的毒性材料。但是由泵输送的透析液却含有氯离子对材料有腐蚀性。 2.泵的工作温度范围宽,既要适合在常温37℃左右使用,又要适合在80°—90℃高 I. Overview The pumps used in the artificial kidney dialysis device and the pumps used in other industrial equipment have the following absolutely different special requirements: 1. Because of the indirect contact between the pump and the human blood, the parts in the pump body must not have any damage Toxic material of the human body. However, the dialysate delivered by the pump contains chloride ions that are corrosive to the material. 2. Pump wide operating temperature range, it is necessary to use at room temperature for about 37 ℃, but also suitable for 80 ° -90 ℃ high
