Abstract

The thermometer consists of a plastics housing (GH) with a tapered end in which is located a temp.-sensitive element such as a temp.-dependent resistor or thermo-element (MF). The sensor is enclosed in a screw-on thin metal tube (UH) of good heat conductivity. The sensor element is in close contact with the tube. The sensor is connected to an electronic circuit and this in turn is connected to a digital display (AN) of, for example, the liq. crystal type. The instrument is powered by battery cells (BA) which are accommodated in a compartment at the end of the housing. They are accessible via a cap (KA). A push-button (TA) switches the device on the off. The instrument is rapid-reading and does not suffer from the disadvantages of the mercury clinical thermometer.

Description

Thermometerthermometer

Bei bekannten Thermometern, die mit Quecksilber als Meß-fühler arbeiten, besteht der Nachteil, daß der Meßvorgang sehr lange dauert, die Gefahr einer Vergiften beim Austritt des Quecksilbers besteht.In known thermometers that work with mercury as a measuring probe, there is the disadvantage that the measurement process takes a very long time, and there is a risk of poisoning exists when the mercury escapes.

Der Erfindung liegt die Aufgabe zu Grunde, den Meßvorgang zu beschleunigen und die Handhabung zu erleichtern und weniger gefährlich zu mischen. Gemäß der Erfindung, welche sich auf ein Thermometer mit einem Meßfühler und einer Anzeigevorrichtung bezieht, wir dies dadurch erreicht, daß an einem Ende des Thermometers ein in seinen elektrischen Figenschaften temperaturabhän, e Meßfühler insbesondere ein temperaturabger Widerstand oder ein thermoelement, in engem Wärmekontakt innerhalb einer gut wärmeleitf higen, insbesondere metallischen Umhüllung untergebracht ist, daß in einem daran anschließenden, vorzugsweise aus Kunststoff bestehenden, Gehäuse eine elektronische Auswerteeinrichtung angeordnet ist und das Gehäuse an seiner Außenseite eine,vorzugsweise digitale, Anzeigeeinrichtung für den gemessenen Temperaturwert aufweist und daß ein abnehmbarer Gehäusedeckel vorgesehen ist, iiber den eine im Inneren des Gehäuses angeordnete Batterie zugänglich ist.The invention is based on the task of accelerating the measuring process and to make handling easier and less dangerous to mix. According to the invention, which refers to a thermometer with a probe and a display device refers, we achieve this by having at one end of the thermometer a in his electrical properties temperature-dependent, e measuring sensor, in particular a temperature-dependent Resistor, or a thermocouple, in close thermal contact within a good heat conductor higen, in particular metallic casing that is housed in it subsequent, preferably made of plastic, an electronic housing Evaluation device is arranged and the housing on its outside one, preferably digital display device for the measured temperature value and that a removable housing cover is provided, over the one inside the housing arranged battery is accessible.

Da der Meßfühler ein elektrisches Bauteil ist, kann der Meßvorgang in sehr kurzer Zeit (einige Sekunden bis 1 Minute) abgewickelt werden und die Nachteile des Quecksilbers (Vergiftungsgefahr) sind vermieden.Since the sensor is an electrical component, the measuring process in a very short time (a few seconds to 1 minute) and the disadvantages of mercury (risk of poisoning) are avoided.

In der Zeichnung ist ein erfindungsgemäßes Thermometer dargestellt, das bevorzugt als Fieberthermometer verwendbar ist. In einer gut wärmeleitenden, vorzugsweise metallischen, Umhüllung UH in Form eines einseitig geschlossenen Zylinders ist ein NeBiffhler 1W so angebracht, daß er einen guten Wärmekontakt zu der Niltillung UH hat, also flächig an dieser anliegt. Als Meßfühler kann ein temperaturabhängiger Widerstand, ein Thermoelement oder ein temperaturabhängiger Halbleiter verwendet werden. Innerhalb eines anschließenden, vorzugsweise aus Kunststoff bestehenden, Gehäuses GH ist eine elektronische Auswerteeinrichtung EA angebracht und ueber Leitungen VL1 mit dem Meßfühler MP verbunden. Der gemessene Temperaturwert wird in einer Gehäuse GH angebrachten, voreugeweise digitalen, Anzeigeeinrichtung AN von außen sichtbar zarge stellt. Am anderen Bnde des Gehäuses GH ist in einer Vertiefung eine Batterie BA angebracht und über Leitungen VL2 mit der elektronischen Auswerteeinrichtung FA verbunden. Die Batterie BA ist über eine abachraubbare Kappe KA von außen zugänglich und damit auswechselbar.In the drawing, a thermometer according to the invention is shown, which is preferably used as a clinical thermometer. In a good heat-conducting, preferably metallic, UH envelope in the form of a cylinder closed on one side a NeBiffhler 1W is attached in such a way that it has good thermal contact with the Niltillung UH has, so lies flat on this. A temperature-dependent Resistance, a thermocouple or a temperature-dependent semiconductor is used will. Within a subsequent, preferably made of plastic existing, housing GH an electronic evaluation device EA is attached and connected to the sensor MP via lines VL1. The measured temperature value is mounted in a housing GH, a digital display device in advance AN provides the frame visible from the outside. On the other volume of the housing GH is in one Well a battery BA attached and via lines VL2 with the electronic Evaluation device FA connected. The battery BA is on a screw-off cap KA accessible from the outside and therefore exchangeable.

Die Umhüllung UH ist zweckmäßig wesentlich dünner als das Gehäuse GH. Sie ist zweckmäßig abnehmbar, insbesondere abschraubbar ausgebildet. Am Gehäuse GH ist zweckmäßig ein Taster TA angebracht, der zur Ein- und Ausschaltung des Gerätes verwendet wird. Die Anzeigeeinrichtung AN besteht vorteilhaft aus Flüssigkeitszellen (LED).The casing UH is expediently much thinner than the housing GH. It is expediently designed to be removable, in particular unscrewable. On the housing GH, a button TA is conveniently attached to switch the device on and off is used. The display device AN advantageously consists of fluid cells (LED).

Neben der Anwendung als Pieberthermometer kann die Erfindung -gegebenenfalls bei entsprechend anderer Dimensionierung der Umfüllung Vii und des Gehäuses GH auch fiir andere Temperaturmessungen verwendet werden.In addition to the use as a Pieberthermometer, the invention - if necessary if the decanting Vii and the housing GH are also dimensioned differently used for other temperature measurements.
