Medical Eponyms
Boyle Intratracheal ether apparatus (1912)
Boyle Intratracheal Insufflation of Ether 1912

Apparatus that has been devised by Mr. G. E. Gask and myself for the intratracheal insufliation of ether. Air is driven from the bellows A, through hot water in the bottle c (the tap B is for air, and B I is a reserve tap for oxygen if necessary). The air then passes through E, over the surface of the ether in the smaller bottle, and so on to the gum-elastic catheter F. When it is desirable to give air without ether, E E are turned off and G is turned on.

Boyle Machine 1919 Lancet

The main points are : (1) each cylinder is provided with a fine adjustment reducing valve (the valves are so constructed that they can be fitted to any ordinary English cylinder); (2) the principle of the “sight feed ” has been adopted ; (3) there is a small spirit lamp for warming the reducing valve to the nitrous oxide cylinder; (4) a pressure gauge is attached to the oxygen cylinder; (5) a small rebreathing bag is attached, together with an ordinary 3-way stopcock and face-piece; (6) an ether bottle is connected up in the circuit; (7) the machine has been made in three sizes’

Boyle-Davis Gag

Boyle ‘imported’ the Canadian Davis mouth gag that then became known as the Boyle-Davis gag. In 1921, Boyle purchased a mouth gag modified for use in tonsillectomies and designed by S. Griffith Davis (1867-1934). Boyle published a paper on the gag in 1922 and then added a description to the third edition of his influential textbook Practical anaesthetics – subsequently the gag became better known as the Boyle, or Boyle-Davis, gag.

The gag shown by the accompanying illustration is a copy of one designed by Dr. Davis and was brought back by me from America. It combines gag and tongue retractor.

Controversies

Sometimes difficult to find original papers. Boyle published many papers in the Lancet, under his preferred title of H. Edmund G. Boyle. This has led to the authorship being shared in many cases between two physicians…H. Edmund and G. Boyle
