Abstract
Es wird ein Infrarot-Strahlungsthermometer, insbesondere ein Ohr-Fieberthermometer, mit einer im wesentlichen stabförmigen und biegsamen Meßspitze (10) zur Erfassung der zu messenden Infrarotstrahlung beschrieben, die an ihrem vorderen Ende (12) eine abgerundete Endfläche aufweist, so daß ein verkantungsfreies Einführen der Meßspitze (10) in den Gehörgang eines Benutzers möglich ist. Die einfallende Infrarotstrahlung wird entweder durch zumindest einen im Meßspitzenkopf angeordneten Infrarot-Strahlungssensor erfaßt, oder aber durch einen oder mehrere Infrarot-Lichtleiter (18) zu einem oder mehreren Infrarot-Strahlungssensoren (20) weitergeleitet. Vor den/dem Infrarot-Lichtleiter(n) bzw. dem/den Infrarot-Strahlungssensor(en) (20) kann eine Infrarot-Linse (22) zur Fokussierung der einfallenden Infrarotstrahlung angeordnet sein.An infrared radiation thermometer, in particular an ear fever thermometer, is described with an essentially rod-shaped and flexible measuring tip (10) for detecting the infrared radiation to be measured, which has a rounded end surface at its front end (12), so that insertion without jamming the measuring tip (10) in the auditory canal of a user is possible. The incident infrared radiation is either detected by at least one infrared radiation sensor arranged in the measuring tip head, or is passed on through one or more infrared light guides (18) to one or more infrared radiation sensors (20). An infrared lens (22) for focusing the incident infrared radiation can be arranged in front of the infrared light guide (s) or the infrared radiation sensor (s) (20).
Description
Die vorliegende Erfindung betrifft ein, insbesondere ein Ohr-Fie berthermometer, mit einer in einen Ohrkanal einführbaren biegsamen Meßspitze.The present invention relates to a, in particular an ear fie thermometer, with a flexible measuring tip that can be inserted into an ear canal.
Aus der JP-A-8-107884 ist ein Infrarot-Thermometer zur Fiebermessung im Ohr bekannt, das eine in Längsrichtung nachgiebige Meßspitze aufweist. Ein Infrarot-Sensor ist ganz vor ne am Ende der Meßspitze angeordnet. Die Meßspitze ist konisch, wobei ihre Dicke am vor deren Ende weniger als 5 mm beträgt. Diese Meßspitze kann zwar leicht und ausreichend tief in den Ohrkanal eingeführt jedoch nicht richtig aufs Trommelfell hin ausgerichtet werden, da sie aufgrund ihrer geringen Dicke im Ohrkanal hin- und herwackeln kann. Wenn aber das Trommelfell überhaupt nicht oder nur teilweise im Blickfeld liegt, weicht die ermittelte Tempe ratur stark von der Trommelfelltemperatur ab, die als genaues Maß für die Körperkerntem peratur gilt. Bei einer Wiederholungsmessung mit etwas veränderter Ausrichtung ergibt sich dann oft ein anderer Temperaturmeßwert, d. h. der Anwender stellt eine unzureichende Wie derholgenauigkeit fest. Daher müssen im Grunde stets mehrere Messungen mit leicht unter schiedlichen Ausrichtungen durchgeführt werden. Die höchste der dabei gemessenen Tem peraturen hat die geringste Abweichung zur Trommelfelltemperatur, obgleich keine Garantie dafür besteht, daß diese auch wirklich genau gemessen wurde. Die bekannte Meßspitze hat ferner den Nachteil, daß der Infrarot-Sensor in der dünnen Spitze nicht ausreichend ther misch isoliert werden kann, wodurch ebenfalls die Meßgenauigkeit beeinträchtigt wird.An infrared thermometer for fever measurement in the ear is known from JP-A-8-107884, which has a flexible tip in the longitudinal direction. An infrared sensor is in front ne arranged at the end of the measuring tip. The probe tip is conical with its thickness at the front the end of which is less than 5 mm. This probe tip can be light and sufficient inserted deep into the ear canal but not properly aligned with the eardrum, because it can shake back and forth in the ear canal due to its small thickness. But if that If the eardrum is not at all or only partially in view, the determined temp gives way temperature strongly depend on the eardrum temperature, which is an exact measure for the core of the body temperature applies. A repeat measurement with a slightly different orientation results in then often another temperature reading, i.e. H. the user presents an insufficient how accuracy. Therefore, basically several measurements with always slightly under different alignments are carried out. The highest of the measured tem temperature has the slightest deviation from the eardrum temperature, although no guarantee is that it was really measured exactly. The well-known measuring tip has further the disadvantage that the infrared sensor in the thin tip is not sufficient ther can be mixed isolated, which also affects the measurement accuracy.
Die Aufgabe der vorliegenden Erfindung besteht in der Schaffung eines Infra rot-Strahlungsthermometers, insbesondere eines Ohr-Fieberthermometers, mit einer Meßspitze, die so ausgestaltet ist, daß sie nicht nur ausreichend tief in den Gehörgang eines Benutzers eingeführt werden kann, sondern dann auch möglichst genau aufs Trommelfell ausgerichtet ist. Eine weitere Aufgabe besteht darin, eine Lokalisierung des Trommelfells zu ermöglichen.The object of the present invention is to create an infra red radiation thermometer, in particular an ear fever thermometer, with a measuring tip, which is designed so that it is not only sufficiently deep in the ear canal of a user can be introduced, but then also aligned as precisely as possible to the eardrum is. Another task is to enable the eardrum to be located.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit einem Infrarot-Strahlungs thermometer, dessen Meßspitze biegsam ist und sich daher an die individuellen Krümmun gen eines jeden Ohrkanals optimal anpassen kann. Im Vergleich zu einer nicht biegsamen Meßspitze wird allein dadurch bereits die Ausrichtung aufs Trommelfell verbessert. This object is achieved according to the invention with infrared radiation thermometer, whose measuring tip is flexible and therefore adapts to the individual curvature can adapt optimally to each ear canal. Compared to a non-pliable one This alone improves the alignment of the measuring tip with the eardrum.
Bei einer bevorzugten Ausführung eines erfindungsgemäßen Thermometers ist die Meßspit ze im wesentlichen stabförmig ausgebildet, wobei das vordere Ende der Meßspitze vor zugsweise abgerundet ist, und das andere Ende ein verdicktes Basisteil aufweist, das ein zu tiefes Einführen der Meßspitze in den Ohrkanal und dadurch Verletzungen des Trommelfells verhindert. Die Meßspitze besitzt sonst einen etwas kleineren Durchmesser als der Ohrka nal, und kann beim Einführen wegen ihres abgerundeten vorderen Endes mühelos den Ohr kanal entlanggleiten.In a preferred embodiment of a thermometer according to the invention, the measuring pit ze formed essentially rod-shaped, the front end of the measuring tip in front is preferably rounded, and the other end has a thickened base part that a deep insertion of the measuring tip into the ear canal and thereby injury to the eardrum prevented. Otherwise the measuring tip has a slightly smaller diameter than the Ohrka nal, and can easily be inserted into the ear due to its rounded front end slide along the channel.
Am vorderen, abgerundeten Ende der Meßspitze kann ein Infrarot-Strahlungssensor ange ordnet sein. Vorzugsweise sind jedoch mehreren Infrarot-Strahlungssensoren auf der ge krümmten Endfläche der Meßspitze zumindest leicht gegeneinander geneigt angeordnet, um ein größeres Blickfeld zu erhalten und die räumliche Temperaturverteilung im Ohr und dar aus die Temperatur und die Lage des Trommelfells relativ zum Blickfeld der Meßspitze be stimmen zu können. Dies erfolgt mittels einer Auswerteeinrichtung, der die Signale der Infra rot-Strahlungssensoren zugeführt werden. Durch eine akustische und/oder optische Si gnaleinrichtung, die von der Auswerteeinrichtung ansteuerbar ist, kann dem Benutzer zudem angezeigt werden, ob eine genaue Messung möglich oder eine andere Ausrichtung der Meßspitze im Ohrkanal erforderlich ist, wodurch nicht nur die Meßgenauigkeit erhöht son dern auch die Handhabung erleichtert wird.An infrared radiation sensor can be attached to the front, rounded end of the measuring tip to be in order. However, there are preferably a plurality of infrared radiation sensors on the ge curved end surface of the measuring tip at least slightly inclined to each other to get a larger field of view and the spatial temperature distribution in the ear and from the temperature and the position of the eardrum relative to the field of view of the measuring tip to be able to vote. This is done by means of an evaluation device which receives the signals of the infra red radiation sensors are supplied. Through an acoustic and / or optical Si The signaling device, which can be controlled by the evaluation device, can also be used by the user whether an exact measurement is possible or a different orientation of the Measuring tip in the ear canal is required, which not only increases the measuring accuracy which also makes handling easier.
Am vorderen Ende der Meßspitze kann auch eine infrarotdurchlässige Linse angeordnet sein, durch die die zu messende Infrarotstrahlung zu einem oder mehreren im Inneren des Thermometers oder der Meßspitze angeordneten Infrarot-Strahlungssensor(en) gelangen kann. Insbesondere kann die Linse die in die Meßspitze eintretende Infrarotstrahlung auf einen oder mehrere Infrarot-Lichtleiter fokussieren, der/die zwischen der Linse und dem/den Infrarot-Strahlungssensor(en) angeordnet ist/sind. Geeignete Infrarot-Lichtleiter sind bei spielsweise flexible AgCl/AgBr-Lichtwellenleiter oder innen versilberte Hohlleiter.An infrared-transmissive lens can also be arranged at the front end of the measuring tip be through which the infrared radiation to be measured to one or more inside the Thermometer or the infrared radiation sensor (s) arranged on the measuring tip can. In particular, the lens can reflect the infrared radiation entering the measuring tip focus one or more infrared light guides between the lens and the lens Infrared radiation sensor (s) is / are arranged. Suitable infrared light guides are included for example, flexible AgCl / AgBr optical fibers or internally silver-coated waveguides.
Besonders vorteilhaft ist es, wenn die Enden der Lichtleiter direkt an der Endfläche der Meß spitze enden und und ihre optischen Achsen dort vorzugsweise einen rechten Winkel mit der Endfläche bilden. Da die Endfläche der Meßspitze gekrümmt ist, ergibt sich bei entspre chender Anordnung der Lichtleiter ein ausreichend großes Blickfeld, so daß die räumliche Temperaturverteilung im Ohr bestimmt werden kann. Den einzelnen Infrarot-Lichtleitern ist vorzugsweise jeweils ein Infrarot-Strahlungssensor zugeordnet. Die Lichtleiter können aber auch bereits knapp unterhalb der Endfläche der Meßspitze enden, so daß sie mit dem Ohr kanal nicht in Berührung kommen können.It when the ends of the light guide directly on the end face of the measuring is particularly advantageous ends and and their optical axes there preferably a right angle with the Form end face. Since the end face of the measuring tip is curved, this results in corre Arranging the light guide a sufficiently large field of view so that the spatial Temperature distribution in the ear can be determined. The individual infrared light guide is preferably each assigned an infrared radiation sensor. The light guides can also end just below the end face of the probe tip, so that it is with the ear can not come into contact with the channel.
