Outline of Final Research Achievements |
We developed a new non-invasive monitoring system for the pulmonary air leak flow.1)We could find three ways to measure the air leak flow quantitatively. Photographic analysis of the air bubbles with the high-speed camera could measure the flow with an error of less than 10%. The capacitance assay revealed that we could grasp an appearance of the air leak, when appropriate measurement condition. (3) Pressure fluctuation measuring and fast Fourier transform method showed that we could measure the air leak flow with an error less than 10%. 2) A prototype of air leak monitoring system was made. We found a method of data transmission synchronization for extending battery life. 3) We could not reach the clinical trial phase by the reason of the technical undevelopment. Pulmonary air leak in the chest drainage unit could be measured and monitored continuously using three differential methods. This new reusable technology could measure the accurate quantity of air leak.
