Abstract

Infrared thermometer for measuring body temperature within the ear, has a measurement tip and a heatable infrared sensor placed on the forward end of the measurement tip. The tip is bendable and has one or more grooves around its outer surface.

Description

Die Erfindung betrifft ein Infrarot-Thermometer, insbesondere zur Fiebermessung im Ohr, mit einer Meßspitze und einem beheizbaren Infrarot-Sensor, der am vorderen Ende der Meßspitze angeordnet ist (nach Patentanmeldung 199 42 214.1).The invention relates to an infrared thermometer, in particular for measuring fever in the ear a measuring tip and a heatable infrared sensor at the front end of the measuring tip is arranged (according to patent application 199 42 214.1).

Beheizbare Infrarot-Sensoren sind aus der DD 1 47 872 und der GB 2090054 A bekannt. In der Hauptanmeldung ist ein beheizbarer Infrarot-Sensor beschrieben, der ein Gehäuse mit einem strahlungsdurchlässigen Fenster, ein Heizelement, einen Temperatursensor und ein Thermopile als Infrarot-Sensor aufweist, der im Gehäuse angeordnet ist.Heated infrared sensors are known from DD 1 47 872 and GB 2090054 A. In the The main application describes a heatable infrared sensor that has a housing with a radiation-permeable window, a heating element, a temperature sensor and a thermopile as an infrared sensor, which is arranged in the housing.

Das aus der Hauptanmeldung bekannte Infrarot-Thermometer hat den Vorteil, daß durch den beheizbaren Infrarot-Sensor praktisch das gesamte vordere Ende der Meßspitze, oder zu­ mindest die Stirnfläche der Meßspitze auf eine gewünschte Temperatur gebracht werden kann. Daher wird beim Einführen der Meßspitze in den Ohrkanal das thermische Gleichgewicht im Ohrkanal praktisch nicht gestört, und werden deshalb Meßfehler vermieden.The infrared thermometer known from the main application has the advantage that heatable infrared sensor practically the entire front end of the measuring tip, or too at least the end face of the probe tip can be brought to a desired temperature. Therefore, the thermal equilibrium in the The ear canal is practically not disturbed, and measurement errors are therefore avoided.

Aus der EP 0588631 A2 ist ein Thermometer mit einer biegsamen Meßspitze bekannt, deren Flexibilität durch mindestens einen auf ihrem äußeren Umfang ausgebildeten Schlitz oder einen Balg erhöht ist. Dadurch läßt sich eine derartige Meßspitze auch bei relativ stark gekrümmtem Ohrkanal tiefer in den Ohrkanal einführen, als dies mit einer starren oder steiferen Meßspitze möglich wäre. Allerdings bewirkt das Biegen der Meßspitze zwangsläufig einen stärkeren Druck auf den Ohrkanal, als dies bei einer starren Meßspitze der Fall ist. Dadurch ist auch ein größe­ rer Wärmeaustausch zwischen der Meßspitze und dem Ohrkanal bedingt, d. h. die Temperatur des Ohrkanals wird durch die gebogene Meßspitze stärker verfälscht, worunter die Meßgenau­ igkeit leidet. Um diesen Wärmeaustausch zu behindern, kann daher die bekannte Meßspitze auf ihrer Außenseite Rippen, Vertiefungen oder dergleichen aufweisen. Am Ende der Meßspitze ist ein herkömmlicher, d. h. nicht beheizbarer Infrarot-Sensor angeordnet.A thermometer with a flexible measuring tip is known from EP 0588631 A2 Flexibility through at least one slot or one formed on its outer circumference Bellow is raised. In this way, such a measuring tip can also be used with a relatively strongly curved one Insert the ear canal deeper into the ear canal than with a rigid or stiffer measuring tip it is possible. However, the bending of the measuring tip inevitably causes a higher pressure on the ear canal than is the case with a rigid measuring tip. This is also a size conditional heat exchange between the probe tip and the ear canal, d. H. the temperature of the ear canal is more distorted by the curved measuring tip, including the measuring accuracy suffering suffers. In order to hinder this heat exchange, the known measuring tip can therefore be used have ribs, depressions or the like on their outside. At the end of the measuring tip is a conventional, i.e. H. non-heatable infrared sensor arranged.

Es ist Aufgabe der vorliegenden Erfindung ein einfach aufgebautes Infrarot-Thermometer anzugeben, das eine gegenüber den bekannten Thermometern verbesserte Meßgenauigkeit hat.The object of the present invention is a simply constructed infrared thermometer to indicate that an improved measuring accuracy compared to the known thermometers Has.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit einem Infrarot-Thermometer, das die im Hauptanspruch aufgeführten Merkmale aufweist. Eine vorteilhafte Weiterbildung ist im Unteranspruch enthalten.This object is achieved according to the invention with an infrared thermometer that the  features listed in the main claim. An advantageous development is in Subclaim included.

Weitere Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels für eine Meßspitze eines erfindungs­ gemäßen Infrarot-Thermometers, die in der einzigen Zeichnung dargestellt ist.Further features and advantages of the present invention result from the following Description of a preferred embodiment for a measuring tip of an invention according infrared thermometer, which is shown in the single drawing.

Die Figur zeigt schematisch eine erfindungsgemäße Meßspitze 10 eines Infrarot-Thermometers mit einem beheizbaren Infrarot-Sensor 20. Der Infrarot-Sensor 20 besitzt ein Gehäuse 14 mit einem infrarotdurchlässigen Fenster 12. Das Fenster 12 besteht vorzugsweise aus Silizium. Ein Infrarot-Sensorelement 18 oder eine Anordnung aus mehreren Infrarot-Sensorelementen ist gegenüber dem Fenster 12 am Gehäuseboden 28 des Infrarot-Sensors 20 angeordnet. Das Infrarot-Sensorelement 18 besteht vorzugsweise aus einem Thermopile. Ein in der Figur nicht dargestellter Temperatursensor ist in an sich bekannter Weise in der Nähe des Infrarot-Sensor­ elements 18 angeordnet. Ebenfalls am Gehäuseboden 28 jedoch außerhalb des Gehäuses 14 des Infrarot-Sensors 20 ist ein Heizelement 16 angebracht.The figure schematically shows a measuring tip 10 according to the invention of an infrared thermometer with a heatable infrared sensor 20 . The infrared sensor 20 has a housing 14 with an infrared-transparent window 12 . The window 12 is preferably made of silicon. An infrared sensor element 18 or an arrangement of several infrared sensor elements is arranged opposite the window 12 on the housing base 28 of the infrared sensor 20 . The infrared sensor element 18 preferably consists of a thermopile. A temperature sensor, not shown in the figure, is arranged in a manner known per se in the vicinity of the infrared sensor element 18 . A heating element 16 is also attached to the housing base 28, but outside the housing 14 of the infrared sensor 20 .
