Description

Verbindungselement für den Anschluss an ein RohrstückConnecting element for connection to a pipe section
Die Erfindung bezieht sich auf ein Verbindungselement für den Anschluss von Medienleitungen, beispielsweise von Schläuchen an ein Rohrstück, wobei wenigstens ein erstes steckerförmiges Verbindungsglied mit wenigstens zwei Schlauchanschlüssen vorgesehen ist, dessen Steckteil in axialer Richtung versetzt radiale Durchbrechungen aufweist, welche mit jeweils einem Schlauchanschluss verbunden sind und wobei wenigstens ein buchsenförmiges Verbindungsglied zur um die Einsteckachse drehbaren Aufnahme des stecker- förmigen Verbindungsglieds vorgesehen ist, dessen Wand in dem den axialen Abständen der radialen Durchbrechungen des steckerförmigen Verbindungsglieds entsprechenden axialen Abständen gleichfalls radiale Durchbrechungen aufweist, wobei zwischen benachbarten radialen Durchbrechungen sowie zum axialen Ende des buchsenförmigen und/oder steckerförmigen Verbindungsglieds die Wand des buchsenförmigen und steckerförmigen Verbindungsglieds relativ zueinander abdich- tende ring- oder scheibenförmige Dichtungen aufweist.The invention relates to a connecting element for the connection of media lines, for example of hoses to a piece of pipe, wherein at least a first connector-shaped connecting member is provided with at least two hose connections, the plug part offset in the axial direction has radial openings, which are each connected to a hose connection and wherein at least one sleeve-shaped connecting member is provided for rotatably about the plug-in axis receiving the plug-shaped connecting member whose wall in the axial distances of the radial openings of the plug-shaped connecting member corresponding axial distances also has radial openings, wherein between adjacent radial openings and the axial end of the socket-shaped and / or plug-shaped connecting member, the wall of the socket-shaped and plug-shaped connecting member is sealed relative to one another in relation to one another. or disc-shaped seals.
Ein derartiges Verbindungselement ist beispielsweise der GB 2190969 A zu entnehmen.Such a connecting element can be seen, for example, GB 2190969 A.
Verbindungselemente für Beatmungsschlauche od.dgl. sind beispielsweise in der DE 29823090 Ul beschrieben. Ein derartiges bekanntes, im Wesentlichen Y-förmig ausgebildetes Verbindungselement mündet in ein weiteres Rohrstück, wobei zur Erleichterung des AufSchiebens und des Abnehmens von Schläuchen eine rutschfeste Oberfläche des Verbindungselements vorgeschlagen wurde .Connecting elements for breathing tubes or the like. are described for example in DE 29823090 Ul. Such a known, substantially Y-shaped connecting element opens into a further tube piece, wherein a non-slip surface of the connecting element has been proposed for facilitating the pushing on and removing of tubes.
Bei modernen Beatmungsgeraten sind in der Regel eine größere Anzahl von Schläuchen anzuschließen, wobei die einzelnen Schläuche jeweils unterschiedlichen Funktionen dienen und daher gesondert im Inneren eines Tubus münden sollen. Eine rasche und fehlerfreie Verbindung eines derartigen Tubus mit einer Mehrzahl von unterschiedlichen Schläuchen ist daher im Sinne der Patientensicherheit von wesentlicher Bedeutung. Schlauchsteckverbindungen sind prinzipiell in unterschiedlicher Ausbildung bekannt. Eine Schlauchsteckverbindung mit einem Steckerteil und einem Innen im Wesentlichen profilkomplementär zum Steckerteil ausgebildeten Buchsenteil ist beispielsweise der DE 3529052 Al zu entnehmen. Eine derartige Ausbildung lässt sich immer nur in einer ganz bestimmten definierten Drehlage mit einander verbinden und ist für die Verwendung in einem Beatmungsgerät insofern weniger geeignet, als je nach Bewegung und Lage des Patienten unterschiedliche Drehmomente von der Schlauchverbindung aufgenommen werden müssen, welche in der Folge auch entsprechende Drehmomente auf den Tubus ausüben, wodurch unerwünschte Belastungen eingebracht werden.In modern ventilators usually a larger number of hoses are to be connected, the individual tubes each serve different functions and therefore should open separately inside a tube. A quick and error-free connection of such a tube with a plurality of different tubes is therefore essential in terms of patient safety. Hose connectors are known in principle in different training. A hose connector with a plug part and an inside substantially profile-complementary to the plug part formed female part can be found for example in DE 3529052 Al. Such a configuration can always connect with each other only in a very specific defined rotational position and is less suitable for use in a ventilator insofar as depending on the movement and position of the patient different torques must be absorbed by the hose connection, which in the episode as well apply appropriate torques to the tube, whereby unwanted burdens are introduced.
Die Erfindung zielt nun darauf ab, ein Verbindungselement der eingangs genannten Art dahingehend weiterzubilden, dass es rasch und verwechslungssicher mit den jeweiligen Gegenan- Schlüssen beispielsweise eines Trachealtubus verbunden werden kann und nach der sicheren Verbindung eine entsprechende Bewegungsfreiheit zulässt, ohne dass hier die dichtende und sichere Verbindung einer Mehrzahl von unterschiedlichen Schläuchen mit jeweils einer Mehrzahl von entsprechend im Tubus angeordneten und in unterschiedlichen Distanzen mündenden Öffnungen beeinträchtigt wird. Es soll somit sowohl die Dichtwirkung als auch die korrekte Zuordnung der einzelnen Schläuche zu den entsprechenden Öffnungen im Inneren eines Tubus in jeder Position aufrecht erhalten werden und eine besonders einfache Verbindung einer Mehrzahl von unterschiedlichen Schläuchen für unterschiedliche Gase oder unterschiedliche Messvorgänge verwechslungssicher gewährleistet werden können. Zur Lösung dieser Aufgabe besteht das erfindungsgemäße Verbindungs- element ausgehend von einer Ausbildung, bei welcher wenigstens ein erstes steckerförmiges Verbindungsglied mit wenigstens zwei Schlauchanschlüssen vorgesehen ist, dessen Steckteil in axialer Richtung versetzt radiale Durchbrechungen aufweist, welche mit jeweils einem Schlauchan— Schluss verbunden sind, wobei wenigstens ein buchsenförmiges Verbindungsglied zur um die Einsteckachse drehbaren Aufnahme des steckerförmigen Verbindungsglieds vorgesehen ist, dessen Wand in dem den axialen Abständen der radialen Durchbrechungen des steckerförmigen Verbindungsglieds entsprechenden axialen Abständen gleichfalls radiale Durchbrechungen aufweist, wobei zwischen benachbarten radialen Durchbrechungen sowie zum axialen Ende des buchsenförmigen und/oder steckerförmigen Verbindungsglieds die Wand des buchsenförmigen und steckerförmigen Verbindungsglieds relativ zueinander abdichtende ring- oder scheibenförmige Dichtungen aufweist, im Wesentlichen darin, dass die Einstecktiefe des stecker- förmigen Verbindungsglieds durch federnde Anschläge begrenzt ist und die federnden Anschläge als federnde Verriegelungsglieder ausgebildet sind und mit Gegenanschlägen verrasten. Dadurch, dass die erfindungsgemäßen Steckteile in buchsenförmigen Verbindungsgliedern drehbar aufgenommen sind und die jeweils wenigstens zwei Schlauchanschlüsse jedes Steckteils über radiale Durchbrechungen in unterschiedlichen axialen Abständen voneinander münden, wird die Möglichkeit geschaffen, auch bei einem Verdrehen des steckerförmigen Verbindungsglieds die korrekte Einmündung des jeweils radial austretenden Gases oder radial abgezogenen Gases in eine entsprechende Ringnut oder eine entsprechende buchsenseitige Öffnung zu gewährleisten. Die konstruktiv besonders einfache Ausgestaltung von Steckteilen und buchsenförmigen Verbindungsgliedern erlaubt es, jeweils einen Steckteil und ein korrespondierendes buchsenförmiges Verbindungsglied für zwei oder auch mehr Schlauchanschlüsse auszulegen, wobei für den Fall einer größeren Anzahl von Schlauchanschlüssen, und insbesondere für vier oder mehr Schlauchanschlüsse für jeweils zwei derartige Schlauchanschlüsse Steckteile mit einem ersten Durchmesser entsprechend dem Außendurchmesser und für die jeweils weiteren Steckteile von diesen ersten Steckteilen verschiedene Außendurchmesser gewählt werden, sodass eine sichere Zuordnung der jeweiligen Anschlüsse über eine einfache Steckverbindung gelingt. Zu diesem Zweck ist die Ausbildung bevorzugt so getroffen, dass für eine die Anzahl von an einem ersten steckerförmigen bzw. dem entsprechenden buchsenförmigen Verbindungsglied übersteigende Anzahl von Schlauchanschlüssen weitere steckerförmige bzw. buchsenföπτiige Verbindungsglieder mit von den ersten Verbindungsgliedern verschiedenen Außen- bzw. Innendurchmessern vorgesehen sind. Es können somit Schlauchan- Schlüsse, welche der Messung des Drucks und/oder der GasZusammensetzung dienen, mit einem Steckteil mit größerem oder kleinerem Durchmesser als der Durchmesser des Steckteils für die Zufuhr von Gasen und ggf. von Gasen, welche mit unterschiedlicher Pulsfrequenz gleichzeitig oder konsekutiv an verschiedenen Stellen eingebracht werden sollen, gewählt werden.The invention now aims to develop a connecting element of the type mentioned in that it can be connected quickly and confusion with the respective counter-statements, for example, a tracheal tube and after the secure connection allows a corresponding freedom of movement, without here the sealing and safe Connection of a plurality of different tubes, each with a plurality of correspondingly arranged in the tube and opening at different distances openings is impaired. Thus, both the sealing effect and the correct assignment of the individual hoses to the corresponding openings in the interior of a tube should be maintained in every position, and a particularly simple connection of a plurality of different hoses for different gases or different measuring operations can be ensured without confusion. To achieve this object, the connecting element according to the invention, starting from an embodiment, in which at least one first connector-shaped connecting member is provided with at least two hose connections, whose Inserted in the axial direction has radial openings, which are each connected to a hose connection, wherein at least one bush-shaped connecting member for rotatably about the plug-in axis recording of the plug-shaped connecting member is provided, the wall corresponding in the axial distances of the radial openings of the plug-shaped connecting member axial distances equally having radial openings, wherein between adjacent radial openings and to the axial end of the female and / or plug-shaped connecting member, the wall of the female and male connector relative to each other has sealing ring-shaped or disc-shaped seals, essentially in that the insertion depth of the plug shaped connecting member is limited by resilient stops and the resilient stops are designed as resilient locking members and counter-attacks lock. Characterized in that the plug-in parts according to the invention are rotatably received in sleeve-shaped connecting members and each open at least two hose connections each plug-in part through radial openings at different axial distances from each other, the possibility is created, even with a twist of the plug-shaped connector, the correct mouth of each radially exiting gas or radially withdrawn gas to ensure a corresponding annular groove or a corresponding socket-side opening. The structurally particularly simple embodiment of plug-in parts and bush-shaped connecting members makes it possible to design a plug-in part and a corresponding bush-shaped connecting member for two or more hose connections, wherein in the case of a larger number of hose connections, and in particular for four or more hose connections for two such Tube connections plug-in parts with a first diameter corresponding to the outer diameter and for the other plug-in parts of these first plug-in parts different outer diameter are selected so that a secure assignment of the respective connections via a simple plug connection succeed. For this purpose, the embodiment is preferably such that for a number of hose connections exceeding the number of male and female connectors respectively, further male or female connectors are provided with outer diameters different from the first connectors. It can thus Schlauchan- conclusions, which serve to measure the pressure and / or gas composition, with a plug-in part with a larger or smaller diameter than the diameter of the plug-in part for the supply of gases and possibly gases, which at different pulse rate simultaneously or consecutively be placed in different places.
Prinzipiell muss beim Einstecken des Steckteils in das buchsenförmige Verbindungsglied sichergestellt werden, dass in axialer Richtung die jeweils radial mündenden Anschlüsse miteinander fluchten bzw. in gasdichte Verbindung gebracht werden können. Zu diesem Zweck ist die Ausbildung so getroffen, dass die Einstecktiefe des steckerförmigen Verbindungsglieds durch federnde Anschläge begrenzt ist, wobei gleichzeitig die federnden Anschläge als federnde Verriegelungsglieder ausgebildet sind und mit Gegenanschlägen verrasten. Mittels derartiger federnder Anschläge wird somit zum einen die korrekte Einsteckposition und zum anderen gleichzeitig eine Sicherung gegen Ausziehen bei gleichzeitiger Aufrechterhaltung der Drehbarkeit des Steckteils in der Muffe ermöglicht.In principle, it must be ensured when inserting the plug-in part in the socket-shaped connecting member that in the axial direction, the respectively radially opening terminals are aligned with each other or can be brought into gas-tight connection. For this purpose, the training is such that the insertion depth of the male connector is limited by resilient stops, at the same time the resilient stops are designed as resilient locking members and lock with counter-attacks. By means of such resilient stops is thus on the one hand the correct insertion position and on the other hand at the same time a backup against pulling while maintaining the rotatability of the male part in the sleeve allows.
Konstruktiv besonders einfach lässt sich das Verbindungselement so gestalten, dass die radialen Durchbrechungen von Ringnuten gebildet sind oder in Ringnuten münden, wobei vorzugsweise zwischen benachbarten Ringnuten und außerhalb derselben O-Ringe als Dichtungen angeordnet sind. In besonders einfacher Weise ist die Ausbildung erfindungsgemäß so getroffen, dass die buchsenförmigen Verbindungsglieder tragende Anschlussdosen für die GasZuleitung vor- gesehen sind. Eine, derartige Ausbildung erlaubt es, die Schläuche zwischen der Gaszuleitung oder aber auch dem entsprechenden Messgerät und dem Tubus abzunehmen, wodurch eine jeweils erforderliche Reinigung wesentlich erleichtert wird.Particularly simple design, the connecting element can be designed so that the radial openings are formed by annular grooves or open into annular grooves, preferably between adjacent annular grooves and outside the same O-rings are arranged as seals. In a particularly simple manner, the embodiment of the invention is such that the socket-shaped connecting members carrying connection boxes are provided for the gas supply line. Such a design makes it possible to remove the tubes between the gas supply line or even the corresponding measuring device and the tube, whereby a respective required cleaning is much easier.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. In dieser zeigen Fig.l einen Querschnitt durch ein Steckerteil mit zwei aufgesteckten Schlauchenden und Fig.2 einen Querschnitt durch ein entsprechendes buchsenförmiges Verbindungsglied für die Verwendung gemeinsam mit einem Stecker gemäß Fig.l.The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. 1 shows a cross section through a plug part with two plugged-on hose ends, and FIG. 2 shows a cross section through a corresponding socket-shaped connecting member for use together with a plug according to FIG.
In Fig.l sind zwei Schlauchanschlüsse 1 und 2 ersichtlich, welche an ein Steckteil 3 angeschlossen sind und über im wesentlichen axiale Kanäle 4 und 5 in radiale Durchbrechungen 6 und 7 münden, welche in axialer Richtung benachbart sind. Die Achse ist hierbei schematisch mit der strichpunktierten Linie 8 angedeutet. Der Steckerteil trägt die beiden Schläuche 9 und 10, welche für unterschiedliche Zwecke verwendet werden können. Insbesondere können derartige Schläuche im Falle von Beatmungsgeräten für die Zufuhr von Beatmungsgasen vorgesehen sein, wobei in modernen Beatmungsgeräten Sauerstoff pulsierend bzw. moduliert zugeführt werden kann. Das jeweils mit entsprechenden Fre- quenzen pulsierende Gas soll nun in der Folge an unterschiedlichen Stellen im Inneren eines Tubus münden, so- dass gesonderte radiale Durchbrechungen 6 und 7 zu derartigen unterschiedlichen Positionen im Inneren des Tubus von wesentlicher Bedeutung sind, um die Funktion des Geräts zu ermöglichen. In Fig.l sind mit 11 Klemmspiralen bezeichnet, welche den sicheren Sitz der Schläuche gewährleisten sollen. Mit 12 sind federnde Anschläge in Form von Federbügeln dargestellt , welche in Richtung des Doppelpfeils 13 auswärts schwenkbar mit dem steckerförmigen Verbindungsglied verbunden sind.In Fig.l two hose connections 1 and 2 can be seen, which are connected to a male part 3 and open through substantially axial channels 4 and 5 in radial openings 6 and 7, which are adjacent in the axial direction. The axis is here indicated schematically by the dot-dash line 8. The plug part carries the two tubes 9 and 10, which can be used for different purposes. In particular, such hoses may be provided in the case of respirators for the supply of respiratory gases, which can be fed pulsating or modulated oxygen in modern ventilators. The respective gas pulsating with corresponding frequencies should now open at different points in the interior of a tube, so that separate radial openings 6 and 7 at such different positions inside the tube are of essential importance for the function of the device to enable. In Fig.l are designated by 11 clamping spirals, which should ensure the secure fit of the tubes. With 12 resilient stops in the form of spring clips are shown, which are connected in the direction of the double arrow 13 outwardly pivotally connected to the plug-shaped connecting member.
In Fig.2 ist nun das entsprechende buchsenförmige Verbindungsglied dargestellt, wobei die jeweils mit den radialen Durchbrechungen 6 und 7 fluchtenden radialen Anschlüsse mit 14 und 15 bezeichnet sind. Um nun in verschiedenen Drehlagen des Steckteils gemäß Fig.l die sichere dichtende Verbindung zu gewährleisten, sind zum einem Ringnuten 16 und 17 vorgesehen, welche im Fall der Ausbildung nach Fig.l und 2 am Steckteil vorgesehen sind. Zwischen benachbarten Ring- nuten 16 und 17 und außerhalb derselben sind nun O-Ringe 18 als Dichtungselemente vorgesehen, sodass nach dem Einstecken des steckerförmigen Verbindungsglieds nach Fig.l in die Buchse nach Fig.2 auch in unterschiedlicher Drehlage ein entsprechend sicherer gasdichter Anschluss an die radialen Durchbrechungen 14 und 15 in Fig.2 gewährleistet ist. Diese radialen Durchbrechungen gehen in der Folge in axiale Verbindungsglieder 19 und 20 über, welche im Inneren eines Tubus beispielsweise in unterschiedlicher distaler bzw. proximaler Distanz enden können. Dem Einsteckende 21 des buchsenförinigen Verbindungsglieds benachbart ist eine Ringrippe 22 vorgesehen, welche bei Einschieben des steckerförmigen Verbindungsglieds 3 von den federnden Bügeln 12 übergriffen wird, welche nach kurzer Auslenkung im Sinne des Doppelpfeils 13 in Fig.l in der Folge in der an- schließenden Nut 23 verrasten und auf die Art und Weise einem Ausziehen des Steckerteils aus der Buchse entgegenwirken kann. Mit 24 ist eine Gerätefrontplatte angedeutet, gegen welches die Buchse 26 geschraubt werden kann. Die Einsteckachse ist in Fig.2 wiederum mit 8 bezeichnet, wobei die radialen Bohrungen 14 und 15 durch Schrauben 25 nach außen gedichtet sind. In Figure 2, the corresponding bush-shaped connecting member is now shown, wherein the respectively aligned with the radial openings 6 and 7 radial ports are designated 14 and 15. In order to ensure in different rotational positions of the male part according to Fig.l the secure sealing connection, 16 and 17 are provided for a ring grooves, which are provided in the case of training according to Fig.l and 2 on the male part. Between adjacent annular grooves 16 and 17 and outside thereof are now O-rings 18 are provided as sealing elements, so that after insertion of the male connector according to Fig.l in the socket of Figure 2 in different rotational position a correspondingly secure gas-tight connection to the Radial openings 14 and 15 is ensured in Fig.2. As a result, these radial apertures merge into axial connecting links 19 and 20, which can end in the interior of a tube, for example at different distal or proximal distances. The insertion end 21 of the Buchsenförinigen connecting member adjacent an annular rib 22 is provided, which is overlapped upon insertion of the male connector 3 of the resilient brackets 12, which after a short deflection in the sense of the double arrow 13 in Fig.l in the sequence in the subsequent groove Lock 23 and counteract in the manner of pulling the plug part out of the socket. With 24 an appliance front plate is indicated, against which the socket 26 can be screwed. The insertion axis is again denoted by 8 in FIG. 2, the radial bores 14 and 15 being sealed by screws 25 to the outside.
