Abstract
Air embolism can be a lethal complication of surgical procedures during which venous pressure at the site of surgery is sub-atmospheric or air is forced under pressure into a body cavity. To solve the problem, we developed the air detector using relative dielectric constant change, which is expected to be used broadly in industrial circles. We designed air detection system with air control equipment, detection circuit and LabVIEW system for air sensing. In experiments with a mock system, the proposed system showed a signal difference depending on the amount of air in the Tygon tube of the mock system.
