2114013 9300042 PCTABS00019 Device for measuring the respiration of a person is provided with a strap (1), which can be applied so that it fits around the upper body of the person, and a detector for measuring the variation in the circumference of the upper body caused by respiration. The detector supplies a measurement signal corresponding to this variation to a processing circuit which controls a display device (13) for displaying this variation. The strap (1) is made of an elastic material and can be fitted around the upper body under a desired pre-tension. The detector comprises an elongated element (4) made of non-stretchable material, preferably a cord, which at least virtually extends over the entire length of the strap (1) and is supported by the strap (1). One end of the cord (4) is rigidly coupled to the strap (1) and the other end actuates a transducer (6), which transforms the movement of the element (4) relative to the strap (1) into the measurement signal, which is supplied to the processing circuit. |
