Abstract
Description
Die Erfindung betrifft eine Messvorrichtung für physiologische Parameter nach dem Oberbergriff des Anspruchs 1.The The invention relates to a physiological measuring device Parameter according to the preamble of claim 1.
In der Anästhesie sowie in der Notfall- und Intensivmedizin ist es von großer Wichtigkeit, sehr schnell die ausreichende Versorgung der Organe und des Körpergewebes mit Sauerstoff sowie vorliegende Störungen der Sauerstoffverteilung zu erkennen und zu beurteilen.In anesthesia and in emergency and intensive care it is of great importance, very soon enough Supplying the organs and body tissue with oxygen as well as existing disturbances of the oxygen distribution recognize and judge.
Die Pulsoximetrie mittels SpO2-Sensorik als spektralphotometrisches Verfahren zur kontinuierlichen Messung der arteriellen Sauerstoff-Sättigung des Blutes ist heute als schnelle, kostengünstige und vor allem nichtinvasive Technik der Patientenüberwachung fest etabliert.The Pulse oximetry using SpO2 sensors as spectrophotometric Method for continuous measurement of arterial oxygen saturation of the Blood is today as fast, inexpensive and above all noninvasive technique of patient monitoring firmly established.
Die dabei eingesetzten SpO2-Sensoren stehen als Einwegsensoren, für einmaligen Gebrauch oder als Mehrwegsensoren, für wiederholten Gebrauch zur Verfügung. SpO2-Mehrwegsensoren müssen aus hygienischen und Infektions-Gründen im Gebrauch zwangsläufig gründlich und sicher desinfiziert bzw. gereinigt werden, da sie während ihrer gesamten Nutzungsdauer wiederholt bei verschiedenen Patienten appliziert werden.The used SpO2 sensors stand as disposable sensors, for single use or as multiple-use sensors, for repeated Use available. SpO2 multiway sensors need for hygienic and infectious reasons in use inevitably thoroughly and safely disinfected or cleaned, as it repeats throughout its lifetime be applied to different patients.
Die heute üblichen und angewandten Desinfektionsverfahren für SpO2-Sensoren stehen in letzter Zeit zunehmend auf dem Prüfstand. Vor dem Hintergrund der aktuellen Thematik resistenter Keime in Krankenhäusern und Kliniken besteht ein Bedarf an erhöhter Hygienesicherheit auch bei wieder verwendbaren SpO2-Sensoren.The today common and applied disinfection method for SpO2 sensors are increasingly being put to the test lately. Against the background of the current issue of resistant germs in hospitals and clinics there is a need for increased hygiene safety even with reusable SpO2 sensors.
Um die Ausbreitungsweg/Verschleppung derartiger Keime über mehrfach verwendete SpO2-Sensoren zu unterbinden, wäre das Autoklavieren dieser Sensoren ein sicheres und praktikables Mittel – zumal bei den Anwendern wie Kliniken und Krankenhäuser, die dafür notwendige Technik bereits vorhanden ist. Allerdings sind die gegenwärtig auf dem Markt verfügbaren SpO2-Sensoren entsprechend dem aktuellem Stand der Technik nicht autoklavierbar, nicht dampfsterilisierbar.Around the propagation path / carryover of such germs to prevent multiple used SpO2 sensors, would be Autoclaving these sensors is a safe and practical means - especially among the users, such as clinics and hospitals, for that necessary technology already exists. However, they are present SpO2 sensors available on the market according to the current state of the art not autoclavable, not steam sterilizable.

Alle diese technischen Lösungen lassen als Keimminderungsverfahren lediglich eine Desinfektion zu, als Reduzierung der Anzahl krank machender Keime, so dass von dem behandelten Gegenstand nur eine reduzierte Infektionsgefahr mehr ausgeht.All These technical solutions leave as a method of culling just a disinfection too, as a reduction in the number ill making germs, so that of the treated object only one reduced risk of infection more runs out.
Zielsetzung ist die Abtötung aller Mikroorganismen einschließlich der Inaktivierung von Viren und Sporen bei SpO2-Sensoren durch Sterilisation.objective is the killing of all microorganisms including the inactivation of viruses and spores in SpO2 sensors by sterilization.
Aufgabe der Erfindung ist es, wieder verwendbare SpO2-Sensoren für die Pulsoximetrie zu offenbaren, die geeignet sind, die in Kliniken und Krankenhäusern erforderliche Keimfreiheit aller Komponenten, insbesondere der opto-elektronischen Komponenten, durch das Dampfsterilisieren/Autoklavieren zu gewährleisten.task The invention is to reusable SpO2 sensors for to reveal the pulse oximetry that are suitable in clinics and hospitals required sterility of all components, in particular the opto-electronic components, by steam sterilization / autoclaving to ensure.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die opto-elektronischen Sende- und Empfangseinheiten in Materialien verkapselt sind. Dabei wird sowohl in der Sendeeinheit als auch in der Empfangseinheit jeweils zumindest ein Material eingesetzt, das im messtechnisch relevanten Bereich optisch durchlässig ist. Alle zur Kapselung verwendeten Materialien weisen sowohl einen geringen Wärmeleitwert als auch eine minimale Wasser-Dampf-Diffusion auf. Weiterhin verfügen die Materialien der Kapselelemente über aufeinander abgestimmte Temperaturausdehnungs-Koeffizienten und/oder über Materialeigenschaften, die thermisch bedingte mechanische Spannungen kompensieren.According to the invention solves this problem by the fact that the opto-electronic Transmitter and receiver units are encapsulated in materials. there is used both in the transmitting unit and in the receiving unit in each case at least one material used in metrological relevant area is optically transparent. All for encapsulation used materials both have a low thermal conductivity as well as a minimal water-vapor diffusion. Continue to dispose the materials of the capsule elements over matched Temperature expansion coefficients and / or material properties, compensate the thermally induced mechanical stresses.
Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert.The Invention will become apparent from an embodiment explained.
