Membrane filter LipiGuard® SB

bloodblood bank

Combines LipiGuard filter media technology with 40 μm lock woven microaggregate screen Designed for use with either intra- or post-operatively salvaged blood that may be washed or unwashed, thereby reducing inventory requirements for a number of different filter products Low volume (20 mL) housing allows excellent blood product recovery High flow rate for rapid infusion Easy spike insertion with a secure hold and rapid filter priming Effectively replaces conventional microaggregate filters Latex free Performance Characteristics Fat, leucocyte and C3a (and its immunosuppressive metabolite C3a des Arg77) were studied for both washed and unwashed salvaged blood, obtained intra-operatively and post-operatively, for the following procedures: total hip replacement coronary artery bypass graft knee arthroplasty prostatectomy discectomy ortho-laminectomy femoral osteotomy No statistically significant differences were found for the filter performance using either washed or unwashed, intra- or post-operatively collected blood. Combined performance data are summarized in Figure 1. Combined Performance Data *Pre-filtration fat concentrations (globules/mL) averaged 21,452, 2,081 and 542 for ranges 40 μm, respectively. Fat challenge (volume) was calculated as the product of fat concentration (globules/mL) and volume of blood product (mL). The total volume of fat for each of the three ranges of fat globule sizes was calculated from estimates using the diameters 5, 25 and 60 μm for ranges of fat sizes (40 μm) measured, respectively.
