A device (11) for facilitating tracheotomy. The device comprises a first branch (92), which is adapted to be introduced down the trachea of a patient, such that the end thereof is located below the larynx, and a second branch (114), adapted to be arranged on the outside of the neck with the end thereof located adjacent to the site intended for the tracheostoma. The end of the second branch comprises a guiding tube for a needle, and the end of the first branch comprises a protection plate. When the needle is moved towards the skin through the guiding tube and penetrates the skin and tracheal wall in order to provide said tracheostoma, the needle is directed towards the protection plate, and may engage it after passage through the tracheal wall. In such a manner the other side of the tracheal wall is protected. Furthermore, the tracheostoma will automatically be located at the best position.
