Mass Transfer Ozone-Blood by a Venturi
2019
Ozone therapy is a powerful technique applied for several purposes. One of these modalities is blood ozonation, a complex process that must have regard to the integrity and properties of blood components. In this work a protocol to in vitro blood ozonation applied to a blood bag was developed, using a venturi injector and a centrifugal pump in a closed circuit system. Our results showed that the protocol developed provide small variations of the hematological concentrations; allow us to infer that concentrations of the red and white blood cells and platelet series remain relatively stable during blood ozonation process on gas flux of 1/8 L/min and ozone concentration of 33 and 62 mg/L. This innovative protocol realized indirectly to the blood bag was the potential to minimize bacterial contamination of blood components in blood bank and realizes a high efficiency ozone-blood mass transfer in order to induce by ozone oxidative balance an indirect blood quality status.
