Stored human blood of varying age was passed through polyurethane foam (Bentley) micropore blood transfusion filters. Passage through these filters resulted in decreased screen filtration pressure (SFP) of the blood and increased filter weights. Numerous microaggregates were removed and SFP returned to normal after filtration. Occlusion of the filter occurred after passage of only 2 units of whole blood. On the basis of this research, we conclude that polyurethane foam (Bentley) micropore blood transfusion filters are effective in removal of microaggregates from stored human blood. Because the filtering capacity is not great, it is recommended that when these filters are used during transfusion a new filter be used for each unit of blood administered.
将不同保存时间的人体血液通过聚氨酯泡沫（本特利）微孔输血过滤器。血液通过这些过滤器后，血液的筛滤压（SFP）降低，过滤器重量增加。大量微聚集体被清除，过滤后SFP恢复正常。仅通过2单位全血后过滤器就发生堵塞。基于这项研究，我们得出结论，聚氨酯泡沫（本特利）微孔输血过滤器能有效去除保存的人体血液中的微聚集体。由于过滤能力不大，建议在输血过程中使用这些过滤器时，每输注1单位血液就更换一个新的过滤器。
