One resin-based hemoperfusion device and three charcoal-based hemoperfusion devices were tested to determine their pressure drop and flow uniformity characteristics. Measurements were made on pressure drop versus flow rate using distilled water and on pressure drop versus time using bovine blood. Effluent concentration curves obtained after the step-change introduction of a high molecular weight dye solution to each unit were used to determine the priming volumes of the devices and were interpreted to yield information regarding the uniformities of flow in each device. The pressure drop and priming volume values for the resin-based device were significantly higher than the corresponding values for the charcoal-based units.
测试了一种基于树脂的血液灌流装置和三种基于活性炭的血液灌流装置，以确定它们的压降和流量均匀性特征。使用蒸馏水测量了压降与流速的关系，并使用牛血测量了压降与时间的关系。在向每个装置阶跃引入高分子量染料溶液后获得的流出物浓度曲线，用于确定装置的预充体积，并据此解读以获取有关每个装置中流量均匀性的信息。基于树脂的装置的压降和预充体积值显著高于基于活性炭的装置的相应值。
