Patent

CA 2243403

It is disclosed a device based on active element(s) (1, 25) that can both monitor/measure and control the temperature of a given environment. Such element(s) are characterized by a low thermal capacity and are supplied power by means of a pulse width modulating technique. Monitoring is performed - on the same element(s) - by means of analysis of the temperature relaxation between heating pulses. The element(s) can be controlled to body temperature, thus resulting in a low-power, high-precision, pocket-size and light-weight instrument (pneumotacograph) suitable to perform accurate spirometry measurements. The device can be easily adapted for applications in high precision flow rate measurements and high sensitivity calorimetry as well.

L'invention concerne un dispositif basé sur un ou plusieurs éléments actifs (1, 25) qui peuvent à la fois surveiller/mesurer et commander la température d'un environnement donné. Ces éléments sont caractérisés par une faible capacité thermique et alimentés en courant par une technique de modulation de largeur d'impulsions. La surveillance est réalisée, sur les mêmes éléments, par une analyse de la relaxation thermique entre les impulsions de chauffage. Les éléments peuvent être amenés à la température du corps, ce qui donne un instrument (pneumotachographe) de poche, de faible puissance, très précis et très léger, convenant pour effectuer des mesures spirométriques précises. Le dispositif peut être facilement adapté à des applications destinées aux mesures d'écoulement de haute précision, ainsi qu'à la calorimétrie de haute sensibilité.
