The Provox plug is a first-aid tool for temporarily stopping leakage through the prosthesis. The plug is inserted into the opening of the Provox voice prosthesis with the help of the non-bristled end of a Provox brush. The medallion end can be taped to the skin if desired. Although speech is not possible while the Provox plug is in place, it is possible again after removal of the plug by pulling on the safety strap. The Provox plug can also be helpful to find out whether leakage occurs through or around the prosthesis.
