Airway, laryngeal, single-use

Intended purpose

The laryngeal mask airway is a tubular oropharyngeal airway, to the distal end of which is attached a mask with an inflatable peripheral cuff. It is designed to produce an airtight seal around the laryngeal inlet and so provide a secure airway suitable for spontaneous or controlled ventilation during general anaesthesia. It can be inserted without the use of a laryngoscope in most cases and a muscle relaxant is seldom required. Once in place, it provides a more secure airway control than a facemask and there is no need to support the patient's chin allowing 'hands free' airway management. This is a single use device.
