An insertion tool for inserting a tracheostoma voice prosthesis member into a fistula between oesophagus and trachea. The insertion tool includes an engagement portion for engaging and retaining said tracheostoma voice prosthesis member to be inserted into the fistula, a gripping portion for gripping a safety strap of said member in a firm grip, a shaft portion adapted to be held by one hand of a user, and a release lever arrangement adjacent said shaft portion for operation by a finger of the same hand as is holding said shaft portion, whereby said release lever, after said member being positioned in place in said fistula by operation of said insertion tool by means of said shaft, is adapted to be operated for releasing said member by one-hand operation. A tracheostoma voice prosthesis member and a method for applying said tracheostoma voice prosthesis member are also provided.
1. An insertion tool for inserting a tracheostoma voice prosthesis member into a fistula between oesophagus and trachea, comprising:
an engagement portion for engaging and retaining said voice prosthesis member to be inserted into the fistula;
a gripping portion for gripping a safety strap of said voice prosthesis member in a firm grip, the gripping portion comprising a support surface and a flap, wherein the safety strap is to be held between the support surface and the flap;
a shaft portion adapted to be held by one hand of a user;
a release lever arranged adjacent said shaft portion for operation by a finger of the same hand that is holding said shaft portion, wherein the release lever comprises a shoulder constructed to hold the flap in place so that the safety strap is held in the gripping portion between the support surface and the flap;
whereby said release lever, after said voice prosthesis member being positioned in place in said fistula by operation of said insertion tool by means of said shaft, is constructed to be depressed so that the shoulder no longer holds the flap in place.
