An In Vitro Pilot Study Comparing the Novel HemoClear Gravity-Driven Microfiltration Cell Salvage System with the Conventional Centrifugal XTRA™ Autotransfusion Device

Figure 2

(a) Schematic illustration of the HemoClear multilayer, micropore filtration technology. The filtration module comprises an inlet for the shed blood to enter. Two outlets lead the diluted plasma (outlet I) and concentrated cells (outlet II) to collection bags. The internal design of the membrane yields a cross-flow current of shed blood cells from the inlet to outlet II, preventing blockage of the pores. (b) The pores only allow passage of fluids (yellow) and solutes (blue), while red blood cells remain on top of the filtration layer (grey). (c) Highly accurate nanotechnology is used to achieve pores of exactly 2.3 microns in diameter.
