摘要
A detector and counter for drainage devices is provided which will detect the passage of air through an underwater seal chamber. A signal is transmitted as a result of the detection of the presence of air or a bubble within an underwater seal chamber and an output circuit responsive to these signals measures the time interval between bubbles. In addition, a counter counts the total number of bubbles passing through the underwater seal over a selected period of time. The bubble detector when used with a pleural drainage device provides a diagnostic tool for a physican in determining the condition of a patient with a pleural air leak by indicating the elapsed time between bubbles and the total volume of air leak over the selected period of time.
