Embodiment 1
[0056] An adsorption hemodialyzer, such as figure 1 As shown, there are liquid inlet end cap 101, blood adsorption chamber 102, hemodialysis chamber 103, liquid outlet end cap 104, hollow adsorption filament 105, hollow fiber membrane 106, and sealants 112, 113, 114. Its main body is composed of a blood adsorption cavity 102 and a hemodialysis cavity 103 connected in series.
[0057] The liquid inlet end cover 101 is placed on the upper end surface of the blood adsorption cavity 102 , the end cover has a liquid replenishment port 107 , and the side of the blood adsorption cavity 102 is provided with a blood inlet port 108 .
[0058] The liquid outlet cover 104 is placed on the lower end surface of the hemodialysis cavity 103 .
[0059] The hollow adsorption filament 105 is folded into a U shape and placed in the blood adsorption cavity 102 , with the filament bundle opening facing the fluid replacement port 107 and fixed and sealed with a sealant 112 . The surface micropore ...
Embodiment 2
[0064] Such as figure 2 As shown, on the basis of Example 1, the hollow adsorption filaments in the blood adsorption chamber are replaced with solid adsorption filaments 205, and the solid adsorption filaments are fixed inside the blood adsorption chamber with the isolation net 211. After switching to solid adsorption silk, this patent no longer has the fluid replenishment function in Embodiment 1 when in use, and no fluid replenishment port is provided.
Embodiment 3
[0066] In Example 2, the solid adsorption filament 205 can be replaced with activated carbon or adsorption resin balls, the surface micropore diameter is 1nm-40nm, and the specific surface area is 300-1500m 2 / g.
