A rearward portion of the female coupler connects to a second tube or a vacuum source. Interiors of the first tube or the vacuum applicator, the male coupler, the female coupler, and the second tube or the vacuum source are fluidly connected, such that a vacuum may be provided to the vacuum applicator. The female coupler includes a clearing valve that connects an exterior of the clearing valve to the interior of the female coupler, upon application of a fluid thereto, to allow clearing of the second tube.
