Abstract
Ein Infrarotthermometer, insbesondere zur klinischen Verwendung, umfasst eine Infrarotaufnahme- und Strahlungsschaltung mit einem Sensor, der die Infrarotstrahlung einer Infrarotstrahlungsquelle aus einer Entfernung erfassen kann, und eine Freigabeschaltung, die mit der Sensierschaltung verbunden ist, um eine Funktion der letzteren auszuwählen und/oder zu aktivieren, wenn der Abstand des Sensors von der Quelle kleiner oder gleich einem vorgegebenen Wert ist; die Freigabeschaltung umfasst einen kapazitiven Näherungsschalter mit wenigstens einer Steuerelektrode, die auf Schwankungen des kapazitiven Feldes in dessen Umgebung empfindlich ist.An infrared thermometer, in particular for clinical use, comprises an infrared recording and radiation circuit with a sensor which can detect the infrared radiation of an infrared radiation source from a distance, and an enable circuit connected to the sensing circuit to select and / or to a function of the latter activate if the distance of the sensor from the source is less than or equal to a predetermined value; the enable circuit comprises a capacitive proximity switch having at least one control electrode which is sensitive to variations in the capacitive field in its environment.
Description
Die Erfindung betrifft ein Thermometer mit dem Hauptzweck, klinische Fernmessungen der Hauttemperatur durchzuführen. Thermometer dieser Art sind in verbreitetem Gebrauch, insbesondere zum Messen der Hauttemperatur in der Nähe der Temporalarterie.The invention relates to a thermometer with the main purpose of performing clinical remote measurements of the skin temperature. Thermometers of this type are in widespread use, in particular for measuring the skin temperature in the vicinity of the temporal artery.
Diese Thermometer müssen normalerweise in Kontakt mit der betreffenden Hautfläche platziert werden, da, wenn dies nicht geschieht, die von ihnen gelieferten Messungen sehr ungenau sind. Dies liegt daran, dass die Messungen stark durch Fehler beeinflusst werden, die insbesondere durch den Abstand des Sensors von der Haut des Patienten verursacht sind. Da diese Thermometer in der Pädiatrie weit verbreitet sind, ist es bevorzugt, sie nicht in direktem Kontakt mit der Hautoberfläche zu platzieren, da ein solcher Kontakt es z. B. schwierig machen würde, die Temperatur eines schlafenden Patienten zu messen, ohne ihn aufzuwecken.These thermometers usually need to be placed in contact with the skin area concerned, since if they do not, the measurements they provide are very inaccurate. This is because the measurements are strongly influenced by errors, especially caused by the distance of the sensor from the skin of the patient. Since these thermometers are widely used in pediatrics, it is preferable not to place them in direct contact with the skin surface, since such a contact z. B. would make it difficult to measure the temperature of a sleeping patient without waking him up.
Aus diesem Grund sind Thermometer entwickelt worden, um ausreichend zuverlässige Messungen zu liefern, wenn der Sensor in einem geeigneten Abstand von der Haut des Patienten gehalten wird. Ein Beispiel für diese Thermometer ist in
Die Verwendung von Lichtquellen hat jedoch eine Reihe von Nachteilen, darunter die Tatsache, dass ein schlafender Patient dadurch plötzlich aufwachen kann, mit möglicherweise schädlichen Auswirkungen auf die Pupille, wenn sie versehentlich von hoch konzentrierten Lichtstrahlen getroffen wird. Außerdem kann, wenn die verwendete Lichtquelle kein ausreichend kaltes Licht liefert, die Konzentration der Lichtstrahlung auf einen Punkt Veränderungen der gemessenen Temperatur hervorrufen.However, the use of light sources has a number of drawbacks, including the fact that a sleeping patient may suddenly wake up with potentially deleterious effects on the pupil if accidentally struck by highly concentrated light rays. In addition, if the light source used does not provide sufficiently cold light, the concentration of light radiation at one point can cause changes in the measured temperature.
Hauptaufgabe der Erfindung ist, ein Infrarotthermometer zu schaffen, das strukturell und funktionell konstruiert ist, um die oben erwähnten Nachteile des genannten Standes der Technik zu überwinden.The main object of the invention is to provide an infrared thermometer which is constructed structurally and functionally to overcome the above-mentioned disadvantages of the said prior art.
Das Problem wird erfindungsgemäß gelöst durch ein Infrarotthermometer gemäß den angegebenen Ansprüchen.The problem is solved according to the invention by an infrared thermometer according to the specified claims.
Die Merkmale und Vorteile der Erfindung werden deutlich anhand der nachfolgenden detaillierten Beschreibung eines bevorzugten aber nicht ausschließlichen Ausführungsbeispiels, das nur zur Veranschaulichung und ohne Beschränkungsabsicht mit Bezug auf die beigefügte
In dieser Zeichnung bezeichnet die Nummer
Erfindungsgemäß umfasst die Freigabeschaltung einen kapazitiven Näherungsschalter
Die Erfindung erreicht so die gesteckten Ziele und bietet dabei zahlreiche Vorteile im Vergleich zum Stand der Technik. Zu diesen Vorteilen gehört die Tatsache, dass die Erfindung es ermöglicht, den Sensor direkt und wiederholt in Bezug auf die Haut des Patienten zu positionieren, ohne dass ein Kontakt mit dem Patienten notwendig ist, und insbesondere ohne Signale zu erzeugen, die die Ruhe des Patienten stören oder mit der laufenden Messung wechselwirken und diese verfälschen können.The invention thus achieves the objectives set and offers numerous advantages over the prior art. Among these advantages is the fact that the invention makes it possible to position the sensor directly and repeatedly with respect to the skin of the patient, without requiring contact with the patient, and in particular without generating signals that affect the patient's calm disturb or interfere with the current measurement and can distort it.
