Laryngeal mask airway with concentric drainage of oesophagus discharge |
September 7, 1993 |
| A laryngeal mask airway is described which is fitted with an evacuation or drainage tube which passes through the back of the mask and terminates concentrically within an inflatable-cuff formation at the distal end of the mask. In the case of a laryngeal mask which relies on an inflatabl |
