A New Method for Eliminating Micro-Bubbles in the Extracorporial Blood Circulation System
Recently, in the medical field, especially in surgery, remarkable progress has been made in the area of artificial organs such as the artificial lung. Unfortunately, these organs sometimes have a major and most serious problem which occurs when air-bubbles intermix into blood. Usually, air-bubbles in the extracorporial circulation system produced by various sources such as the artificial heart-lung system are eliminated by various types of mechanical blood filters before the blood recirculates into the human vein. However, air-bubbles which are only a little larger or smaller than the mesh size of the filter can pass through it and these air-bubbles could sometimes be micro-embolic in the peripheral circulation bed and hence cause tissue damage.
