A liquid extraction/discharge device includes an elongate, hollow tube having a proximal end and a distal end and defining an internal passage therethrough, a flexible and resilient squeeze bulb defining a chamber therein and engaged with the proximal end of the tube for providing communication between the passage and the chamber, and a relatively rigid base mounted on the tube adjacent to the proximal end for engagement with the squeeze bulb to provide a support against which the squeeze bulb may be compressed.
