Zur Lösung dieser Aufgabe ist ein medizinisches Handmessgerät entsprechend dem Patentanspruch 1 ausgebildet.to solution This object is a medical hand-held device according to the claim 1 formed.

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 device according to the invention corresponds in shape and / or size, for example an electrical or electronic temperature measuring device (fever thermometer). The measuring device its measuring tip or its provided PH measuring sensor (PH meter) allow in a small design it, by introducing the probe into a wound quickly and accurately the PH value of that wound reliable to investigate.

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.Of the The invention is based on the finding that acute wounds, which do not require further special care, one PH in the range between about 2.8-3.3, whereas at a pH above 4.5, especially at a PH value in the range between 5 and 8 to one to close chronic wound is that of a special care, such as a surgical Treatment and a. also for removing infected or contaminated Tissues or tissue residues needed.

Weiterbildungen, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung von Ausführungsbeispielen und aus den Figuren. Dabei sind alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination grundsätzlich Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung. Auch wird der Inhalt der Ansprüche zu einem Bestandteil der Beschreibung gemacht.Further developments, Advantages and applications The invention will become apparent from the following description of exemplary embodiments and from the figures. All are described and / or illustrated illustrated features for itself or in any combination in principle the subject of the invention, independently from their summary in the claims or their dependency. Also, the content of the claims becomes a part of the description.

Die Erfindung wird im Folgenden anhand der Figur, die in vereinfachter Darstellung ein Handmessgerät 1 zum Messen von für die Wundheilung relevanten Parametern zeigt, näher erläutert.The invention will be described below with reference to the figure, which in a simplified representation of a hand-held device 1 for measuring parameters relevant for wound healing, explained in more detail.

Das in der Figur allgemein mit 1 bezeichnete Handmessgerät ist beispielsweise hinsichtlich Größe und Form bekannten elektrischen bzw. elektronischen Temperaturmessgeräten (Fieberthermometer) entsprechend ausgebildet und besteht im Wesentlichen aus einem langgestreckten Gehäuse 2, in welchem u. a. eine Auswert- und Messelektronik 3 sowie eine Batterie 4 als Stromquelle untergebracht sind, sowie aus einer Messspitze 5, die bei der dargestellten Ausführungsform u. a. einen Sensor zur Messung der Temperatur, einen Sensor zur Messung des PH-Wertes (PH-Meter) sowie einen Sensor zur Messung der elektrischen Leitfähigkeit der mit der Sondenspitze 5 berührten Umgebung aufweist. Selbstverständlich können diese Sensoren oder wenigstens zwei dieser Sensoren auch von einem gemeinsamen Sensorelement gebildet sein, welches Messsignale liefert, die sämtlichen vorgenannten Parametern (Temperatur, PH-Wert und Leitwert) oder aber wenigstens zwei Parametern entsprechen.This in the figure generally with 1 designated hand-held measuring device is formed, for example, in size and shape known electrical or electronic temperature measuring devices (fever thermometer) accordingly and consists essentially of an elongated housing 2 in which inter alia an evaluation and measuring electronics 3 as well as a battery 4 are housed as a power source, as well as from a measuring tip 5 , which in the illustrated embodiment, inter alia, a sensor for measuring the temperature, a sensor for measuring the pH value (PH meter) and a sensor for measuring the electrical conductivity of the probe tip 5 has touched environment. Of course, these sensors or at least two of these sensors can also be formed by a common sensor element which supplies measurement signals which correspond to all the aforementioned parameters (temperature, pH and conductance) or at least two parameters.

An dem Gehäuse 2 ist eine Anzeige 6, beispielsweise in Form eines LCD-Displays vorgesehen, an der die gemessenen Werte der Temperatur, des PH-Wertes und der Leitfähigkeit angezeigt werden, und zwar bei aktiviertem Messgerät. Das Aktivieren bzw. Einschalten und Deaktivieren bzw. Ausschalten des Messgerätes erfolgt beispielsweise durch Taster 7, die ebenfalls am Gehäuse 2 vorgesehen sind.On the case 2 is an ad 6 , for example, in the form of an LCD display, where the measured values of temperature, PH value and conductivity are displayed, with activated measuring device. Activating or switching on and off or switching off the meter takes place, for example, by a button 7 also on the case 2 are provided.

Mit 8 ist eine Kappe bezeichnet, die auf die Messspitze 5 aufschiebbar ist und mit der die Messspitze 5 nach und/oder vor jeder Verwendung des Handmessgerätes 1 mit einem geeigneten Medium 1 gereinigt und desinfiziert wird. Gleichzeitig dient die Kappe 8 bzw. ein in dieser Kappe enthaltenes Medium auch zur Kalibrierung zumindest des für die PH-Messung und Leitwert-Messung verwendeten Sensors. Die Behandlungsflüssigkeit ist beispielsweise in einem Reservoir der Kappe 8 untergebracht und/oder die Kappe 8 ist als Spülkappe zum Anschluss an eine Spüleinrichtung ausgebildet, von der das Behandlungsmedium der Kappe 8 bevorzugt in einem geschlossenen, die Kappe 8 einschließenden Kreislauf zugeführt wird.With 8th is a cap that points to the measuring tip 5 is slidable and with the the measuring tip 5 after and / or before each use of the handheld instrument 1 with a suitable medium 1 is cleaned and disinfected. At the same time serves the cap 8th or a medium contained in this cap also for calibrating at least the sensor used for the PH measurement and conductance measurement. The treatment liquid is, for example, in a reservoir of the cap 8th housed and / or the cap 8th is designed as a flushing cap for connection to a purging device, of which the treatment medium of the cap 8th preferably in a closed, the cap 8th enclosing circuit is supplied.

Das Handmessgerät 1 wird beispielsweise im klinischen Bereich bei der Visite (Wundenvisite) zur schnellen Ermittlung der für die Wundheilung relevanten Parameter, PH-Wert, Temperatur und Leitfähigkeit verwendet und hierfür mit der Messspitze 5 in die visitierte Wunde eingeführt. Liegt bei der Messung der PH-Wert deutlich über 3,2, beispielsweise im Bereich zwischen 4,5 und 8, so ist dies ein Hinweis auf eine chronische Wunde, die einer besonderen Versorgung, beispielsweise auch einer operativen Versorgung bedarf.The hand-held device 1 is used, for example, in the clinical area during the visit (wound visit) for the rapid determination of parameters relevant for wound healing, pH value, temperature and conductivity and for this purpose with the measuring tip 5 introduced into the visited wound. If the PH value is clearly above 3.2, for example in the range between 4.5 and 8, this is an indication of a chronic wound requiring special care, for example also an operative care.

Die Erfindung wurde voranstehen an einem Ausführungsbeispiel beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrunde liegende Erfindungsgedanke verlassen wird.The Invention has been described above on an exemplary embodiment. It is understood that numerous changes and modifications are possible, without thereby the inventive concept underlying the invention will leave.
