摘要：
A proximal body portion (210) of a detection apparatus for detecting the presence of a substance on a surface includes pump portion (124, 142) and a proximal probe portion (111, 120) in fluid communication with one another. A controller (225) processes signal readings sensed by the parameter sensor (P, P1 or P2) and determines whether the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112′) of a distal probe portion (110) of the detection apparatus (100, 100′, 100″, 100″a, 100″b, 100″c, 100″d, 100c). The controller (225) transmits a signal that changes dynamic pressure at the distal tip (112, 112′) upon determining that the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112′).
