Bragg-Paul Pulsator, model II, Europe, 1938-1939
The Bragg-Paul Pulsator was designed to give artificial respiration to patients who could not breathe for themselves because of illnesses such as diphtheria or during brain surgery. An air bag was placed around the patient’s chest and abdomen and rhythmically inflated and deflated by an electric pump, moving the chest muscles and allowing the patient to breathe. The apparatus was invented in 1933 by Sir William Henry Bragg (1862-1942), an English physicist, for a friend who was experiencing muscle paralysis. Bragg’s friend used the Pulsator for three years. Robert William Paul (1869-1943), an English scientific instrument maker (who had also been a pioneer of cinema) designed the apparatus. This example was given to the Royal Institution in 1940 “for the guidance of future production”.
