Medtronic autoLog® Autotransfusion

Exceptionally Effective

The autoLog™ Autotransfusion System processes blood collected from a surgical site to produce washed red blood cells for return to a patient at a later time. This is achieved with only one kit and one program. An innovative bowl design, coupled with sophisticated software, provides an effective combination for autotransfusion procedures.

Medtronic autoLog® Cell Saver2-stage filling cycle:

  • Initial stage
    - first FILL at 600 ml/min.
    - Pump momentarily stops at initial detection of red cells.
  • Final stage
    - Second FILL at 250 ml/min initiated after red cells settle.
    - Red cells packed as tightly as possible.

Variable-speed wash cycle

  • Level sensor monitors red cell pack
  • Software controls pump "pulsations" of saline into the bowl.
    - Minimizes red cell spillage.
    - Only 250 ml of saline required for effective washout of extraneous
