Description

Die Erfindung betrifft einen Spirometer in Taschenformat (1) zur Messung des maximalen Luft-Zeit-Volumens in Exspiration.The invention relates to a pocket-sized spirometer ( 1 ) for measuring the maximum air-time volume during expiration.

Bekannte vergleichbare Spirometer besitzen eine Zeigeranzeige, die zu Ablesefehlern führen kann. Außerdem ist bei bekannten Spirometern der Atemwiderstand in Exspiration relativ hoch, was zu eine Verfälschung des Ergebnisses führt.Known comparable spirometers have a pointer display, which can lead to reading errors. It is also known Spirometers the breathing resistance in expiration relatively high what leads to a falsification of the result.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Ablesung des gemessenen Wertes mittels direkter Ziffernanzeige durch ein elektronisches Display (2) zu erreichen, einen wesentlich niedrigeren Atemwiderstand in Exspiration zu erzielen um eine genaue, zielgerichtete Messung zu ermöglichen. Durch die Verwendung des Schaufelrades (3) zur Meßwertermittlung ist eine niedrige Bauweise gewährleistet.The object of the invention is to achieve a simple reading of the measured value by means of a direct numerical display on an electronic display ( 2 ), to achieve a significantly lower breathing resistance during expiration in order to enable an accurate, targeted measurement. The use of the paddle wheel ( 3 ) to determine the measured value ensures a low construction.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Der Spirometer (1) besitzt ein elektronisches Display (2) zur Anzeige des maximalen Atemzeitvolumens in Volumen pro Zeit. Das Mundstück (4) ist auswechselbar. Durch die Verwendung des Schaufelrades (3) ergibt sich eine flache Bauweise mit längsovalem bzw. rechteckigem Lufteintritt (5) und Strömungskanal (6). Die Luftströmung verläuft senkrecht zur Schaufelradachse (7) und treibt dieses an. Die Drehzahl des Schaufelrades wird durch eine Reflex- oder Gabellichtschranke (8) erfaßt und anschließend elektronisch ausgewertet und auf dem Display (2) angezeigt.The spirometer ( 1 ) has an electronic display ( 2 ) to show the maximum respiratory volume in volume per time. The mouthpiece ( 4 ) can be replaced. The use of the paddle wheel ( 3 ) results in a flat design with a longitudinally oval or rectangular air inlet ( 5 ) and flow channel ( 6 ). The air flow runs perpendicular to the bucket wheel axis ( 7 ) and drives it. The speed of the paddle wheel is detected by a reflex or fork light barrier ( 8 ) and then electronically evaluated and shown on the display ( 2 ).

Durch die geringe Masse des Schaufelrades ist ein geringer Atemwiderstand und eine genaue Messung gewährleistet.Due to the low mass of the paddle wheel, there is less Respiratory resistance and an accurate measurement guaranteed.

Claims (1)

Atemmeßgerät zur digitalen elektronischen Erfassung des maximalen Atemzeitvolumens in Exspiration, dadurch gekennzeichnet, daß die Luftströmung in Exspiration ein Schaufelrad antreibt, welches eine Lichtschranke unterbricht und somit einer nachgeschalteten Elektronik die Auswertung und digitale Anzeige in Gasvolumen/Zeit ermöglicht.Breath measuring device for the digital electronic recording of the maximum breathing time volume in expiration, characterized in that the air flow in expiration drives a paddle wheel, which interrupts a light barrier and thus enables downstream evaluation and digital display in gas volume / time.
