Ein Handmessgerät zur Bestimmung des pH-Wertes der Haut ist aus der Gebrauchsanleitung „HI 98109 . HI 98110 pH Testers for Skin“ der Firma HANNA instruments bekannt.A hand-held device for determining the pH of the skin is described in the instructions for use "HI 98109. HI 98110 pH Tester for Skin "from HANNA instruments.
Aufgabe der Erfindung ist es, ein Handmessgerät aufzuzeigen, mit dem der Zustand von Wunden schnell und zuverlässig festgestellt werden kann und welches hierfür insbesondere auch für den Einsatz im klinischen Bereich geeignet ist.The object of the invention is to show a hand-held device with which the condition of wounds can be detected quickly and reliably and which is particularly suitable for use in the clinical area.
Zur Lösung dieser Aufgabe ist ein medizinisches Handmessgerät entsprechend dem Patentanspruch 1 ausgebildet.To solve this problem, a medical hand-held measuring device according to the patent claim 1 is formed.
Am Gehäuse des erfindungsgemäßen medizinischen Handmessgerätes ist eine das pH-Meter aufweisende Messspitze vorgesehen, die zum Einführen in eine Wunde ausgebildet ist, wobei die Anzeige zur optischen Anzeige oder Darstellung des gemessenen pH-Wertes ausgebildet ist.Provided on the housing of the medical hand-held measuring device according to the invention is a measuring tip having the pH meter, which is designed to be inserted into a wound, wherein the display is designed for optically displaying or displaying the measured pH value.
Das medizinische Handmessgerät gemäß der Erfindung entspricht in Form und/oder Größe beispielsweise einem elektrischen oder elektronischen Temperaturmessgerät (Fieberthermometer). Das Messgerät dessen Messspitze oder dessen dort vorgesehener pH-Mess-Sensor (pH-Meter) in kleiner Bauform ermöglichen es, durch Einführen der Messspitze in eine Wunde den pH-Wert dieser Wunde schnell und zuverlässig zu ermitteln.The medical hand-held measuring device according to the invention corresponds in shape and / or size, for example, to an electrical or electronic temperature measuring device (fever thermometer). The measuring device whose measuring tip or its designated pH measuring sensor (pH meter) in a small design make it possible to quickly and reliably determine the pH value of this wound by inserting the measuring tip into a wound.
Der Erfindung liegt dabei die Erkenntnis zugrunde, dass akute Wunden, die einer weiteren besonderen Versorgung grundsätzlich nicht bedürfen, einen pH-Wert im Bereich zwischen etwa 2,8 - 3, 3 aufweisen, wohingegen bei einem pH-Wert größer 4,5, insbesondere bei einem pH-Wert im Bereich zwischen 5 und 8 auf eine chronische Wunde zu schließen ist, die einer besonderen Versorgung, beispielsweise einer chirurgischen Behandlung u.a. auch zum Entfernen von infiziertem oder kontaminiertem Gewebe oder Geweberesten bedarf.The invention is based on the finding that acute wounds, which in principle do not require further special care, have a pH in the range between about 2.8-3.3, whereas at a pH greater than 4.5, in particular at a pH in the range between 5 and 8, it can be concluded that there is a chronic wound, a special care, for example a surgical treatment, inter alia also for removing infected or contaminated tissue or tissue residues needed.
Das medizinische Handmessgerät gemäß der Erfindung weist eine Reinigungs- und Desinfektionskappe für die Messspitze auf, wobei die Reinigungs- und Desinfektionskappe ein Mittel zur Kalibrierung zumindest des pH-Meters enthält.The medical hand-held measuring device according to the invention has a cleaning and disinfection cap for the measuring tip, wherein the cleaning and disinfecting cap contains a means for calibrating at least the pH meter.
