[Tracheal cannula with a detachable mucus container].

The author gives an account of the development of a new-type tracheal cannula. The article discusses the mechanism of a modified tracheal cannula with press-stud, attached to a mucus container. This container prevents mucus coughed accidentally on surrounding objects or people; makes it possible for its wearer to breath moist, body heated air. The apparatus can be concealed under a buttoned-up shirt, which makes it aesthetically advantageous. According to first clinical experiences, this mucus container, together with the built-in deflector plates and ventilation holes gives--apart from the above benefits--unimpaired breathing. Its application may help those patients who--due to total removal of larynx or other reasons--are compelled to wear a tracheal cannula, to adapt to society.
