Description
Einrichtung zur Ermittlung der Fähigkeit der Nase, in der Atmungsluft enthaltenen Staub zu binden Untersuchungen haben zu der Erkenntnis geführt, daß die Fähigkeit der menschlichen Nase, eingeatmeten Staub festzuhalten und damit sein Eindringen in die Lungen zu verhindern, ausschlaggebend ist für die Entstehung bestimmter Gewerbekrankheiten (Staublunge). Damit ist das praktische Bedürfnis nach einer Vorrichtung gegeben, die es gestattet, die Fähigkeit der Nase zur Bindung eingeatmeten Staubes zu messen.Device for determining the ability of the nose to act in the air we breathe contained dust to bind Investigations have led to the knowledge that the ability of the human nose to hold on to inhaled dust and be with it Preventing penetration into the lungs is crucial for the development of certain Industrial diseases (pneumonia). So there is the practical need for a device given, which allows the ability of the nose to bind inhaled dust to eat.
Es sind Einrichtungen bekannt, die den Staubgehalt eines Gases, z. B. auch der Luft eines Arbeitsraumes, messen. Gemäß der Erfindung werden die an sich bekannten Einrichtungen in folgender Weise benutzt: Mittels eines Gebläses oder einer Pumpe wird staubhaltige Luft in die Nasenlöcher der Versuchsperson eingeblasen. Ferner ist ein in den Mund eingeführtes Rohr vorgesehen, durch das die eingeblasene Luft wieder austritt. Vor dem Eintritt in die Nase und nach dem Austritt aus dem Mund wird in an sich bekannter Weise die Konzentration des Staubes in der ein- bzw. ausströmenden Luft gemessen. Durch zwei Meßinstrumente (Gasuhren, Strömungsmesser) wird die ein- bzw. ausströmende Luftmenge bestimmt und dadurch das richtige Funktionieren der Vorrichtung kontrolliert.There are devices known that the dust content of a gas, for. B. also measure the air in a work room. According to the invention, the known devices used in the following way: By means of a fan or a pump is used to blow dusty air into the test subject's nostrils. Furthermore, a tube inserted into the mouth is provided through which the blown tube Air comes out again. Before entering the nose and after exiting the Mouth, in a known manner, the concentration of the dust in the one resp. outflowing air measured. Using two measuring instruments (gas meters, flow meters) the amount of air flowing in and out is determined and thus correct functioning controlled by the device.
Auf der Zeichnung ist beispielsweise eine Ausführung des Erfindungsgegenstandes dargestellt.The drawing shows, for example, an embodiment of the subject matter of the invention shown.
Die Pumpe P erzeugt einen Luftstrom, der in dem Gefäß W Staub aufwirbelt und sich in der Flasche F mit diesem gleichmäßig durchmischt. Der staubhaltige Luftstrom passiert dann die Gasuhr U,. und eine Waschflasche Wa, in der sich der grobe Staub. niederschlägt. N ist das an die Nasenlöcher anzusetzende Ansatzstück, M .das in den Mund einzuführende Rohr. Die `Meßeinrichtungen bestehen jeweils aus einem Zylinder Z1 bzw. Z2, der bei geschlossenem oberen und geöffnetem unteren Hahn evakuiert werden kann. Wird nach erfolgtem Evakuieren und Einschalten des von der Pumpe durch Nase und Mund getriebenen Luftstromes bei geschlossenem unteren Hahn der obere geöffnet, so wird aus dem zur Nase fließenden bzw. vöm Munde kommenden Luftstrom eine dem Zylinderinhalt entsprechende Luftmenge durch die Düse D, bzw. D2 und die Kammer KI bzw. K. in den Zylinder Z1 bzw. Z2 gesaugt. An dem der Düse D1 bzw. D2 unmittelbar gegenüberstehenden Deckel der Kammer befindet sich ein Glasplättchen, auf dem sich der in der herausgesaugten Luftmenge enthaltene Staub niederschlägt. Die Auszählung des Staubes erfolgt unter dem Mikroskop. U2 ist die zweite Gasuhr zur Messung des aus dem Munde austretenden Luftstromes.The pump P generates a flow of air that stirs up dust in the vessel W. and mixes evenly with this in the bottle F. The dusty air stream then passes the gas meter U ,. and a washing bottle Wa for the coarse dust. precipitates. N is the attachment to be attached to the nostrils, M. The in tube to be inserted into the mouth. The `measuring devices each consist of a cylinder Z1 or Z2, which are evacuated with the upper valve closed and the lower valve open can. Is used after evacuation and switching on of the pump through the nose and mouth-driven air flow with the lower cock closed, the upper one opened, so the air flow flowing to the nose or coming from the mouth becomes a dem Volume of air corresponding to the cylinder content through nozzle D or D2 and the chamber KI or K. sucked into the cylinder Z1 or Z2. Directly at that of the nozzle D1 or D2 opposite cover of the chamber is a glass plate on which the dust contained in the extracted air precipitates. The count of the dust takes place under the microscope. U2 is the second gas meter for measuring the stream of air emerging from the mouth.
