Ausgehend vom Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, eine Vorrichtung zur Steuerung des Atemgasflusses eines Patienten hinsichtlich der vorgenannten Nachteile zu verbessern.outgoing The object of the present invention is the prior art therein, a device for controlling the breathing gas flow of a patient to improve in terms of the aforementioned disadvantages.
Diese Aufgabe wird durch eine Vorrichtung zur Steuerung des Atemgasflusses eines Patienten mit den Merkmalen des unabhängigen Anspruchs 1 gelöst.These Task is a device for controlling the flow of breathing gas a patient with the features of independent claim 1 solved.
Der Vorteil der Erfindung besteht im Wesentlichen darin, dass durch das neuartige Einlageelement, welches die innere Kontur des Atemgasblockes bedeckt, der Atemgasblock nicht mehr mit Atemgas eines Patienten in Kontakt kommt und hierdurch eine aufwendige Reinigung und Desinfektion der Komponenten des Atemgasblockes sowie des Atemgasblockes selbst entfällt. Die erfindungsgemäße Vorrichtung ermöglicht eine einfache Konstruktion und Herstellung, da die mit Atemgas kontaminierten Komponenten der Vorrichtung nicht mehr nach jedem Patienten durch Dampf-Autoklavieren aufbereitet werden müssen. An die Materialien der Komponenten des Atemgasblockes können geringere Anforderungen hinsichtlich der Betriebsbedingungen gestellt werden.Of the Advantage of the invention consists essentially in that by the novel insert element, which is the inner contour of the breathing gas block covered, the breathing gas is no longer with breathing gas of a patient comes into contact and thereby a complex cleaning and disinfection of Components of the respiratory gas block and the respiratory gas block itself is eliminated. The inventive device allows a simple design and manufacture, since the components contaminated with respiratory gas stop the device after each patient by steam-autoclaving must be prepared. On the materials of the components of the breathing gas block can lower Requirements with regard to the operating conditions.
Zudem ergibt sich für den Anwender ein reduzierter Aufwand in der Wiederaufbereitung der Vorrichtung nach einer Anwendung an einem Patienten. Es sind keine hohen Temperaturanforderungen an die Materialien infolge des Entfallens des Dampf-Autoklavierens erforderlich. Die Lebensdauer dieser Vorrichtung zur Steuerung des Atemgasflusses eines Patienten kann aufgrund der geringeren Belastung der Komponenten deutlich erhöht werden. Ferner kann auf Filterelemente sowohl im Bereich des Atemgaszuführungskanals als auch im Bereich des Atemgasauslasskanals des Atemgasblockes verzichtet werden. Damit kann eine deutliche Reduzierung des pneumatischen Widerstandes innerhalb des Atemgaskanals erzielt werden.moreover arises for the user a reduced effort in the reprocessing of the device after an application to a patient. There are no high temperature requirements the materials due to elimination of steam autoclaving required. The life of this device for controlling the Breathing gas flow of a patient may be due to lower stress the components increased significantly become. Furthermore, filter elements can be used both in the region of the respiratory gas supply channel and omitted in the area of the breathing gas outlet channel of the breathing gas block become. This can be a significant reduction of the pneumatic Resistance can be achieved within the breathing gas channel.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.advantageous Embodiments of the invention will become apparent from the dependent claims.
Besonders vorteilhaft ist es, das Einlageelement aus einem flexiblen Material, vorzugsweise aus Polyurethan, auszubilden, da es damit optimal die Atemgas führenden Kanäle auskleiden kann. In vorteilhafter Weise sind in dem Einlageelement Anschlüsse zu dem Atemgaszuführungskanal beziehungsweise Atemgasauslasskanal ausgebildet, wobei jeweils eine Dichtung in diese Anschlüsse integriert sein kann. Ferner kann an dem Anschluss zu dem Atemgaszuführungskanal beziehungsweise dem Atemgasauslasskanal jeweils ein Filterelement in dem Einlageelement integriert sein.Especially It is advantageous, the insert element made of a flexible material, preferably of polyurethane, form, since it optimally the breathing gas leading channels can undress. Advantageously, in the insert element connections to the breathing gas supply passage or respiratory gas outlet channel formed, wherein each one Seal in these connections can be integrated. Further, at the port to the breathing gas supply passage or the Atemgasauslasskanal each have a filter element in be integrated with the insert element.
Besonders vorteilhaft ist es, an dem Einlageelement Stützteile vorzusehen, die ein sicheres Positionieren des Einlageelementes in den Atemgasblock ermöglichen. In vorteilhafter Weise können die Stützteile als Käfige konstruiert werden. Es sind aber auch sternförmige oder fächerartige Konstruktionen der Stützteile möglich. Es ist zweckmäßig, das Einlageelement aus zwei tiefgezogenen Folien mit dazwischen befindlichen Stützteilen herzustellen, wobei die tiefgezogenen Folien verschweißt oder verklebt sein können. Besonders vorteilhaft ist es, die Stützkörper für einen Wärmefluss von dem Atemgasblock in das Einlageelement zu nutzen, derart dass an den Stützteilen Heizelemente ausgeführt sind. Ferner können diese Stützteile in vorteilhafter Weise auch Träger für Sensoren, beispielsweise einem Flowsensor oder einem Feuchtigkeitssensor sein. Alternativ dazu können diese Sensoren auch in den Stützteilen integrieren sein.It is particularly advantageous to provide support elements on the insert element, which enable a secure positioning of the insert element into the respiratory gas block. Advantageously, the support parts can be constructed as cages. But there are also star-shaped or fan-like constructions of the support members possible. It is expedient to produce the insert element from two thermoformed films with support parts located therebetween, wherein the thermoformed films can be welded or glued. It is particularly advantageous, the support to use body for a heat flow from the breathing gas block in the insert element, so that are carried out on the support members heating elements. Furthermore, these support parts can also be carriers for sensors, for example a flow sensor or a moisture sensor, in an advantageous manner. Alternatively, these sensors can also be integrated in the support parts.
In einer wiederum weiter bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung ist ein Teil des Einlageelementes als Atemkalkreservoir ausgebildet. Die Integration des Atemkalkes in das Einlageelement ermöglicht einen gemeinsamen logistischen Prozess des Atemkalkes und des Einlageelementes. Dabei kann das Atemkalkreservoir des Einlageelementes in verschiedenen Größen ausgebildet sein. Die Anwendung eines Einlageelementes in einem Atemgasblock ist prinzipiell für alle Arten von Atemgeräten geeignet. Dazu zählen auch unterschiedliche Atemgasantriebe, wie Verdichter, speziell Radialverdichter, Trommel- oder Seitenkanalverdichter und Volumenpumpen wie Bälge, welche elektrisch, mechanisch oder pneumatisch angetrieben werden.In a again preferred embodiment of the device according to the invention a part of the insert element is designed as Atemkalkreservoir. The integration of soda lime in the insert element allows a common logistical process of the soda lime and the insert element. In this case, the Atemkalkreservoir the insert element can be formed in different sizes be. The application of an insert element in a breathing gas block is in principle for all types of respiratory equipment suitable. These include also different breathing gas drives, such as compressors, especially centrifugal compressors, Drum or side channel compressors and volume pumps such as bellows, which be driven electrically, mechanically or pneumatically.
