The present invention provides a blood filter medium, which comprises at least one composite unit, and the composite unit comprises at least one spunlaced hydrophilic nonwoven fabric layer and at least one meltblown hydrophilic nonwoven fabric layer located on the spunlaced hydrophilic nonwoven fabric layer. In which, the spunlaced hydrophilic nonwoven fabric layer comprises a plurality of fiber material, and the cross-sections of the fiber material are respectively provided with at least two ends, and the two ends are formed with a clearance providing the capillarity. The diversion and diffusion effects of the blood filter medium may be increased by the clearance, and the filtering area is increased to reduce the blood loss rate. Meanwhile, the present invention may enhance the blood filtering performance of the blood filter medium to reduce the blood filtering time. Furthermore, the blood filter medium may have lower production cost to meet with the usage and cost benefits for the manufacturers.本發明提供一種血液濾材包含至少一複合單元,該複合單元含有:至少一層水刺型親水不織布層;及至少一層熔噴型親水不織布層,位於該水刺型親水不織布層上;其中,該水刺型親水不織布層包括複數條纖維材,且該等纖維材的橫截面分別具有至少兩端,且該兩端形成一具有毛細作用的間隙。透過該間隙可增加該血液濾材的導流及擴散效果,以及增加過濾面積,以降低血液損失率,同時,可提升該血液濾材對血液的過濾效能,以減少血液過濾時間。再者,該血液濾材的生產成本低,可符合業者的使用效益及成本效益。1‧‧‧第一複合單元11‧‧‧水刺型親水不織布層12‧‧‧熔噴型親水不織布層2‧‧‧第二複合單元21‧‧‧水刺型親水不織布層22‧‧‧熔噴型親水不織布層3‧‧‧第三複合單元31‧‧‧水刺型親水不織布層32‧‧‧熔噴型親水不織布層4‧‧‧第四複合單元41‧‧‧水刺型親水不織布層42‧‧‧熔噴型親水不織布層
