Device in the form of a tracheostomy tube or a prosthesis to restore the voice for insertion into a tracheostoma

A device for insertion into a tracheostoma comprising a cylindrical apparatus body (1) having a longitudinal axis and provided one on an outer surface of the device body (1) flexible flange (2) having a direction of use, in which it is of substantially from the outer surface the device body (1) extends to the outside and an insert direction, has in which it resiliently to the longitudinal axis of the device body (1) to be folded, and an axis extending in the apparatus body insertion aid (3) for holding the flange (2) in its resiliently folded orientation, wherein the flange (2) of at least two blades (21) is formed and the vanes (21) is a shape memory having that orients the blade (21) from the longitudinal axis of the device body (1) away, characterized in that the insertion (3 ) is a pin-shaped body having a means (31) for holding the flange (2) and the wings (21) The area of ​​the wing tip (22) having a recess (23) are provided, in which the means (31) is detachably inserted, wherein the recesses (23) are round and the means (31) has a spherical tip (331), which a connection (332) with small diameter of the proximal end of the insertion (3) forms, with the outer diameter of the insertion aid (3) and the tip (331) corresponds at most to the inner diameter of the device body (1) and the insertion (3) of the device body (1) is pulled out, so that the wings (21) of the flange (2) are deployed.
