pro·bang 
(prōbăng′)
(prōbăng′)n.
A long, slender, flexible rod having a tuft or sponge at the end, used to remove foreign bodies from or apply medication to the larynx or esophagus.
[Alteration (probably influenced by PROBE) of earlier provang, perhaps from alteration of obsolete provet, surgical probe, from French éprouvette, from éprouver, to test, try out, from Old French esprover : es-, out (from Latin ex-, ex-) + prover, to prove; see PROVE.]
