Abstract:
Device for treating ronchopathy and sleep apnoea adapted to be placed in the oro-pharynx and in the pre-buccal region of a patient while sleeping, which comprises in combination:an anatomical shaped curved tube having a length such that in situ its proximal end reaches at least the base of the tongue and its distal end projects out of the buccal cavity; reinforcing means fixed to said tube near said distal end adapted to reinforce said tube in the area of the teeth and the lips and to prevent crushing said tube; a buccal base integral with said reinforcing means and adapted to bear against an external face of the lips; the base and said reinforcing means being made of a material having a hardness greater than that of the material of the tube to increase its rigidity where the teeth bear on it; so that, placed in the oro-pharynx of the patient while sleeping, airflow produced by the patient can pass freely and without obstacle between the outside and the area downstream of the base of the tongue, without blockage and without causing vibration of surrounding soft tissue including the soft palate, the base of the tongue and the pharyngeal wall.
