Device for timing pulmonary respiration of an individual at a predetermined rate

摘要

a. Device for timing pulmonary respiration of an individual at a predetermined rate. b. Device characterised in that it is composed of an integrator 6 with adjusting time constant 7 controlling a light source 9, the integrator itself being controlled by a comparator 12 which receives the input signal S1 from the integrator and its output signal S2 in order to make use of the integrator 6 using a bistable applied to the input 10 of the integrator 6. c. The invention relates to respiratory exercises. <IMAGE>
