A device for maintaining an airway in a patient

Abstract

A device adapted for maintaining an airway in a patient, the device comprising a mask, the mask adapted to form a seal around the laryngeal inlet when properly inserted into a patient and an airway tube for providing ventilation gases and / or anaesthetic gases through the mask and to the lungs of the patient when the device is properly inserted in a patient, wherein the airway tube has a first proximal opening and a second proximal opening.

Description

technical field [0001] The present invention relates to a laryngeal mask, and more particularly to a laryngeal mask which also allows insertion of a medical device, such as an endotracheal tube, into a patient. Background technique [0002] The maintenance of a viable airway is critical during surgical procedures performed under general anesthesia. For many years, maintenance of a viable airway during such surgical procedures has been accomplished by inserting an endotracheal tube into the patient. The endotracheal tube is usually inserted through the mouth or nose into the larynx, past the vocal cords and into the trachea. Because the endotracheal tube must be inserted through the vocal cords, there is often difficulty in properly positioning the endotracheal tube. [0003] Many supraglottic airway devices or laryngeal masks can now also be used to maintain a viable airway. The pioneering laryngeal mask was developed by Dr. Archibald Brain and described in UK Patent No. ...
