DEVICES CONSTRUCTIVE ARRANGEMENT AND METHODS APPLIED TO THORAXIC CIRTOMETRY

摘要

The present invention relates to an apparatus and method for the measurement of expansion and contraction in general and particularly for monitoring the respiration of patients by measuring the torso perimeter (thoracic cirtometry) in real time, particularly to measure thoracic expansibility in patients under physiotherapy or clinical treatment or in any case that requires the evaluation of the mobility of the thorax. The measurement is made through a resistive sensor that produces a voltage signal proportional to the position of a sliding cursor. Other embodiments can use a capacitive sensor and a linear encoder as well.
