Birth of The Laryngeal Mask Concept
Dr Archie Brain began studying the anatomy and physiology of the Upper Airway in relation to existing airways. Dr Brain concluded that current techniques for connecting artificial airways to the patient were not ideal, reasoning that if the respiratory tree is seen as a tube ending at the glottis and the objective is to connect this tube to an artificial airway, the most logical solution was to create a direct end-to-end junction. Existing airway devices clearly failed to form this junction; the face-mask sealed against the face, and the ETT penetrated too far so that the junction was created within the trachea, instead of at its beginning. Dr Brain wrote in his diary in May 1981, "Better, use a loop fitting into the anatomical loop of space surrounding the larynx, with a projection downwards into the oesophagus, which could be hollow, to drain regurgitant fluid.“

Famous quotes containing the words birth of the, birth, mask and/or concept:
“Before the birth of the New Woman the country was not an intellectual desert, as she is apt to suppose. There were teachers of the highest grade, and libraries, and countless circles in our towns and villages of scholarly, leisurely folk, who loved books, and music, and Nature, and lived much apart with them. The mad craze for money, which clutches at our souls to-day as la grippe does at our bodies, was hardly known then.”
—Rebecca Harding Davis (1831–1910)
“Some say that ever ‘gainst that season comes
Wherein our Saviour’s birth is celebrated,
The bird of dawning singeth all night long:
And then, they say, no spirit dare stir abroad,
The nights are wholesome, then no planets strike,
No fairy tale nor witch hath power to charm,
So hallow’d and so gracious is the time.”
—William Shakespeare (1564–1616)
“Vice, in its true light, is so deformed, that it shocks us at first sight; and would hardly ever seduce us, if it did not at first wear the mask of some virtue.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx’s concept was more comprehensive and less time-bound than Freud’s.”
—Erich Fromm (1900–1980)
