Title
(EN) TYMPANIC THERMOMETER
(FR) THERMOMETRE POUR LE TYMPAN
Abstract
(EN)
A tympanic thermometer (100) incorporates a temperature detector element (122) comprised of twin thermopiles (216, 230), each thermopile including a set of sensing junctions (220, 234) and a set of reference junctions (218, 232) configured so that three sets of junctions (234, 218, 232) of the four sets of junctions (220, 234, 218, 232) sense only the temperature of the ambient environment, while the fourth set of junctions (220) receives energy from both the ambient environment and from the tympanic membrane (120) of a patient (105) whose temperature is being taken. The energy received from the tympanic membrane (120) is intentionally not bandwidth limited, enabling an accurate temperature measurement to be calculated which is substantially independent of wavelength. A light pipe (116), which preferably has a dielectric coating internally applied, is optionally included to assist in carrying radiation from the tympanic membrane (120) to the fourth set of junctions (220).

Un thermomètre (100) pour le tympan comprend un élément (122) détecteur de température constitué de thermocouples jumelés (216, 230), chaque thermocouple comprenant un jeu de jonctions de détection (220, 234) et un jeu de jonctions de référence (218, 232), disposés pour que trois jeux de jonctions (234, 218, 232) des quatre jeux de jonctions (220, 234, 218, 232) ne détectent que la température de l'environnement ambiant, alors que le quatrième jeu de jonctions (220) reçoit l'énergie aussi bien de l'environnement ambiant que de la membrane du tympan (120) du patient (105) dont on prend la température. L'énergie reçue de la membrane du tympan (120) n'est pas limitée du point de vue largeur de bande, ce qui permet une mesure précise de la température qui est sensiblement indépendante de la longueur d'onde. Un conduit optique (116), qui comporte de préférence un revêtement diélectrique appliqué à l'intérieur, peut être éventuellement inclus pour faciliter le transfert des radiations de la membrane du tympan (120) vers le quatrième jeu de jonctions (220).
