<p>A mucus extractor comprises a symmetric vessel (1) with an inlet connection (14) for a mucus tube (16) and an outlet connection (15) for a suction tube (17). The diaphragm (12) peripheral is captive at the plane of symmetry. The diaphragm (12) is separating a space (22) to be collapsed by suction from a receiving space (23) into which mucus is drawn by the suction. The effect of the diaphragm (12) is to prevent mucus from entering the suction tube (17) which could be both unpleasant and dangerous.</p> |
