Abstract
Description
Die Erfindung bezieht sich auf ein medizinisches Beatmungssystem Oberbegriff Patentanspruch 1 sowie auf eine beheizbare Schlauchanordnung mit Temperatursensor gemäß Oberbegriff Patentanspruch 11.The The invention relates to a medical ventilation system generic term Claim 1 and to a heated hose assembly with Temperature sensor according to the preamble Claim 11.
Unter „Schlauchanordnung" sind im Sinne der Erfindung im einfachsten Fall ein einzelner Schlauch für Atemgas, aber auch ein oder mehrere Schläuche mit wenigstens einem Adapter und/oder Anschlussstück zu verstehen.Under "hose arrangement" are within the meaning of Invention in the simplest case a single tube for breathing gas, but also one or more hoses to understand with at least one adapter and / or connector.
Mit Hilfe von modernen Beatmungssystemen konnten Probleme bei der Beatmung von Patienten beispielsweise während Operationen deutlich gesenkt werden. Hierbei spielen neben der Anwendung moderner Beatmungstechniken oder -geräte, die ausreichende Erwärmung und Anfeuchtung des jeweiligen Atemgases bei optimierter Hygiene eine entscheidende Rolle.With Help of modern ventilation systems could be problems with ventilation of patients for example during Operations are lowered significantly. In addition to the application of modern play Ventilation techniques or devices, sufficient warming and humidification of the respective breathing gas with optimized hygiene a crucial role.
Bekannt ist, die Schläuche oder Schlauchsysteme oder- anordnungen von Beatmungssystemen zu beheizen, und zwar beispielsweise durch eine in dem jeweiligen Schlauch verlegte elektrische Schlauchheizung, die im Wesentlichen von einem mit einer Schutzumhüllung umgebenden elektrischen Heizdraht gebildet ist, oder aber durch eine an der Umfangswandung des Schlauches vorgesehene und ebenfalls im Wesentlichen von einem Heizdraht gebildet elektrische Heizung. Zur Steuerung des Heizstromes wird üblicherweise wenigstens ein Temperatursensor verwendet, der dann beispielsweise in einem Adapter an einem Ende des beheizten Schlauches vorgesehen ist.Known is, the hoses or tubing systems or assemblies of respiratory systems heat, for example, by a in the respective hose laid electrical hose heating, which is essentially of a with a protective cover surrounding electric heating wire is formed, or through one provided on the peripheral wall of the hose and also essentially formed by a heating wire electric heater. For controlling the heating current is usually at least one Temperature sensor used, which then, for example, in an adapter is provided at one end of the heated tube.
Speziell bei einem eine ausreichende Feuchtigkeit aufweisendem Atemgas, welches Voraussetzung für eine gute Bronchialschleimverflüssigung ist, kommt es in bekannten beheizten Schlauchsystemen oder Schläuchen vielfach zur Bildung von größeren Mengen an Kondenswasser, und zwar durch einen entsprechenden Temperaturabfall insbesondere auch im Bereich der für den jeweiligen Temperatursensor vorgesehenen Adapter. Bereits eine durchschnittliche Temperaturabsenkung von 0,2°C/cm führt beispielsweise bei einer Länge von 5 cm eines unbeheizten Adapters zu einem Temperaturabfall von 1°C und damit z.B. zu einer Kondenswasserbildung bis zu 2,5 mg/l Atemgas. Ein derartiges Kondenswasser in Beatmungssystemen gefährdet in erster Linie den jeweiligen Patienten, führt aber auch zu technischen Ausfällen und verursacht zusätzlich Kosten.specially at a sufficient moisture-containing breathing gas, which requirement for a good bronchial mucus liquefaction is, it comes in known heated hose systems or hoses many times for the formation of larger quantities condensation, in particular by a corresponding drop in temperature in particular also in the area of for the adapter provided for the respective temperature sensor. Already one average temperature reduction of 0.2 ° C / cm leads for example in a length of 5 cm of an unheated adapter to a temperature drop of 1 ° C and thus e.g. Condensation up to 2.5 mg / l respiratory gas. One Such condensation in respiratory systems is endangered in first and foremost the respective patient, but also leads to technical precipitate and causes additional costs.
Aufgabe der Erfindung ist es, diesen Nachteil zu beheben. Zur Lösung dieser Aufgabe ist ein Beatmungssystem entsprechend dem Patentanspruch 1 ausgebildet. Ein Schlauchsystem oder eine Schauchanordnung ist entsprechend dem Patentanspruch 11 ausgeführt.task The invention is to remedy this disadvantage. To solve this Task is a respiratory system according to the claim 1 formed. A hose system or a hose assembly is executed according to the patent claim 11.
Mit der erfindungsgemäßen Ausbildung wird eine Kondenswasserbildung zuverlässig verhindert. Bei der Erfindung erfolgt die Temperaturmessung im beheizten Bereich des Schlauchsystems, d.h. z. B. im beheizten Schlauch oder aber in einem ebenfalls beheizten Adapter und/oder Y-Stück. Die Erfindung wird im Folgenden anhand der Figuren an Ausführungsbeispielen näher erläutert. Es zeigen:With the training of the invention Condensation is reliably prevented. In the invention the temperature measurement takes place in the heated area of the hose system, i.e. z. B. in the heated hose or in a likewise heated Adapter and / or Y-piece. The invention will be described below with reference to the figures of embodiments explained in more detail. It demonstrate:
