Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of red blood cell washing device, comprises semipermeable membrane chamber 1, is arranged at the Red Blood Cells Suspension import 2 of upper end, semipermeable membrane chamber 1, is arranged at the red blood cell exit 3 of lower end, semipermeable membrane chamber 1, is arranged at the erythrocyte of red blood cell exit 3 lower end and flows out gauge tap 4, be arranged at the washing chuck 5 of outside, semipermeable membrane chamber 1 and the dialysis solution import 6 that is arranged on washing chuck 5 and waste liquid outlet 7.
Described dialysis solution import 6 is provided with dialysis solution input duct 9, and described dialysis solution input duct 9 end is provided with dialysis solution storage bag 8, described dialysis solution input duct 9 is provided with dialysis solution and flows out switch 10.Described waste liquid outlet 7 is provided with waste liquid discharge line 12, and described waste liquid discharge line 12 end is provided with liquid waste collector 11.Described dialysis solution input duct 9 is provided with supercharger 13.Described waste liquid discharge line 12 is provided with decompressor 14.Described Red Blood Cells Suspension import 2 is provided with sealing strip.Described semipermeable membrane chamber 1 is oblate spheroid structure, and semipermeable membrane chamber is the washing area that oblate spheroid structure is conducive to increasing washing Red Blood Cells Suspension, improves detersive efficiency.
