Abstract
Das Quetschventil dient zur Steuerung des Durchflusses in einem Schlauch von medizinischen Instrumenten oder Geräten. Der in einem Gehäuse befindliche Schlauch wird zum Sperren des Durchflusses mit einem von außen unter Federvorspannung am Schlauch anliegenden Sperrelement elastisch verformt und abgequetscht, wobei das Sperrelement zur Freigabe des Durchflusses durch Betätigen eines Hebels gegen die Federvorspannung und unter selbsttätiger Rückverformung des Schlauches verstellt werden kann. Der Schlauch durchläuft einen starren Träger und bildet mit diesem zusammen einen lösbar in eine Aufnahme des Gehäuses steckbare Kartusche als Wechseleinheit.The pinch valve is used to control the flow in a hose of medical instruments or devices. The hose located in a housing is elastically deformed and squeezed to block the flow with a blocking element that is attached to the hose from the outside under spring pretension, the blocking element being able to be adjusted to release the flow by actuating a lever against the spring pretension and automatically reshaping the hose. The hose runs through a rigid carrier and forms together with this a cartridge that can be detachably inserted into a receptacle of the housing as an exchange unit.
Description
Die Erfindung betrifft ein Quetschventil für medizinische Instrumente und Geräte zur Steuerung des Durchflusses in einem Schlauch, wobei der in einem Gehäuse befindliche Schlauch zum Sperren des Durchflusses mit einem von außen unter Federvorspannung am Schlauch anliegenden Sperrelement zur Freigabe des Durchflusses durch Betätigen eines Hebels gegen die Federvorspannung und unter selbsttätiger Rückverformung der Schlauches verstellbar ist.The invention relates to a pinch valve for medical instruments and devices to control the flow in a hose, the one in a housing located hose to block the flow with an outside under Spring preload on the hose locking element to release the Flow by operating a lever against the spring preload and under automatic reshaping of the hose is adjustable.
Bekannte Quetschventile dieser Art (DE 196 24 811 A1) sind in Bezug auf die Verstellmechanik für das Sperrelement konstruktiv aufwendig und aufgrund relativ vieler einzelner und kompliziert gestalteter Teile nur schwer zu demontieren, zu reinigen, zu desinfizieren und/oder zu sterilisieren. Probleme ergeben sich bei solchen Quetschventilen auch regelmäßig im Zusammenhang mit einer einwand freien Dichtung im Bereich der Schlauchenden, so daß das Ventil nicht bzw. zumindest nicht mit hohem Fluiddruck belastet werden kann, zumal sonst auch die Gefahr besteht, daß sich der Schlauch von dem ihm im Ventil zugeordneten Anschluß lösen wird.Known pinch valves of this type (DE 196 24 811 A1) are in relation to the Adjustment mechanism for the locking element is structurally complex and due to relative many individual and complicated parts difficult to dismantle, too clean, disinfect and / or sterilize. Problems arise with such pinch valves also regularly in connection with a fault free seal in the area of the hose ends so that the valve does not or at least can not be loaded with high fluid pressure, especially since otherwise There is a risk that the hose will deviate from that assigned to it in the valve Loosen connection.
Diese Nachteile sollen durch die Erfindung beseitigt werden. Es soll also ein Quetschventil vorgeschlagen werden, das konstruktiv einfach gestaltet und leicht zu Zwecken der Reinigung, Desinfektion bzw. Sterilisation demontierbar ist und das weiterhin mit hohen Fluiddrücken ohne Dichtungsprobleme belastet werden kann.These disadvantages are intended to be eliminated by the invention. So it should be Pinch valve are proposed that are structurally simple and lightweight is removable for cleaning, disinfection or sterilization purposes and that continue to be loaded with high fluid pressures without sealing problems can.
Zur Lösung dieser Aufgabe wird das eingangs erwähnte Quetschventil erfindungs gemäß so ausgebildet, daß der Schlauch einen Träger durchläuft und zusammen mit diesem eine lösbar in eine Aufnahme des Gehäuses steckbare Kartusche als Wechseleinheit bildet. Diese Kartusche kann nach Öffnen des Gehäuses einfach aus dem Gehäuse gezogen werden, so daß dessen Aufnahme und sonstige Teile einschließlich Sperrelement den Mitteln zum Reinigen, Desinfizieren bzw. Sterili sieren frei zugänglich sind, während die gezogene Kartusche insofern gesondert behandelt wird oder eventuell auch als preisgünstiger Einmal-Gebrauchsartikel gegen eine neue Kartusche ausgewechselt wird.To solve this problem, the pinch valve is fiction, mentioned above formed in such a way that the hose passes through a carrier and together with this as a detachably insertable into a receptacle of the housing Exchange unit forms. This cartridge can be easily opened after opening the housing be pulled out of the housing so that its inclusion and other parts including blocking element for cleaning, disinfecting or sterile They are freely accessible, while the drawn cartridge is separate is treated or possibly also as an inexpensive single-use article is exchanged for a new cartridge.
Aufgrund der Ausbildung des Schlauches und des Trägers als Baueinheit in Form einer Kartusche ergibt sich auch die Möglichkeit für eine spezielle und hoch druckbelastbare Dichtung zwischen Schlauch und Gehäuse, indem nämlich der zylindrische Schlauch an seinen beiden Enden jeweils mit einem Teil seiner Länge um zylindrische Endabschnitte des Trägers umgeschlagen ist und Dichtungs elemente zwischen dem Träger und dem Gehäuse bildet.Due to the design of the hose and the carrier as a structural unit in shape A cartridge also gives you the option of a special and high pressure-resistant seal between hose and housing, namely the cylindrical tube at both ends with part of its length is turned around cylindrical end portions of the carrier and sealing forms elements between the carrier and the housing.
Im Gehäuse und im Träger ist jeweils ein radial zur Längsachse des Ventils ver laufender Durchgang für das Sperrelement vorgesehen, das als radial zum Schlauchumfang verstellbarer Stößel ausgebildet ist, der am Hebel angelenkt ist und im Durchgang des Gehäuses radial geführt ist.In the housing and in the carrier is a ver each radially to the longitudinal axis of the valve ongoing passage provided for the locking element, which as radial to Hose circumference adjustable plunger is formed, which is articulated on the lever and is guided radially in the passage of the housing.
Das Gehäuse ist zweckmäßigerweise zweiteilig ausgebildet, wobei ein Gehäuseteil eine Schraubkappe ist, die den anderen Gehäuseteil endseitig übergreift und so mit diesem verschraubt ist, daß die Kartusche zwischen beiden Gehäuseteilen abge dichtet verspannt ist. Im übrigen kann an einem Gehäuseteil ein Schlauchanschluß stutzen und am anderen Gehäuseteil ein Kupplungsteil vorgesehen werden, mit dem das Ventil lösbar mit dem medizinischen Instrument oder Gerät verbunden werden kann.The housing is expediently formed in two parts, one housing part is a screw cap that engages over the other end of the housing part and thus with this is screwed that the cartridge abge between the two housing parts seals tight. Otherwise, a hose connection can be made to a housing part connect and a coupling part are provided on the other housing part with which the valve is releasably connected to the medical instrument or device can be.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Es zeigt: An exemplary embodiment of the invention is described below with reference to the drawing described. It shows:
Fig. 1 die Seitenansicht eines endoskopischen Instrumentes mit einem am proxi malen Instrumentenende angeordneten Quetschventil im Längsschnitt und Fig. 1 is a side view of an endoscopic instrument with a pinch valve arranged at the proximal end of the instrument in longitudinal section and
Fig. 2 das Quetschventil gemäß Fig. 1 in größerem Maßstab. Fig. 2 shows the pinch valve of FIG. 1 on a larger scale.
Das Quetschventil 1 ist mittels einer Kupplung mit dem Instrument 2 lösbar verbunden. Das Ventilgehäuse 3 besteht aus einem ersten Gehäuseteil 4, an dem sich ein Kupplungsstutzen 4a zur Verbindung mit einem hierzu passenden Kupp lungsteil des Instruments befindet, und aus einem zweiten Gehäuseteil 5 in Form einer Schraubkappe, die im Bereich 6 auf einem Gewindestutzen des ersten Gehäu seteils verschraubt ist.The pinch valve 1 is detachably connected to the instrument 2 by means of a coupling. The valve housing 3 consists of a first housing part 4 , on which there is a coupling socket 4 a for connection to a fitting coupling part of the instrument, and a second housing part 5 in the form of a screw cap, which in the region 6 on a threaded connector of the first housing is partly screwed.
Der Gehäuseteil 4 ist mit einer zylindrischen Ausnehmung als Aufnahme 7 für eine Kartusche 8 versehen. Diese besteht aus einem starren Träger 9 mit einem axial durchgehenden Kanal 10 und einem den Kanal 10 durchlaufenden Schlauch 11, der an seinen beiden Endbereichen jeweils über einen Stutzen des Trägers 9 so umge schlagen ist, daß sich Schlauchabschnitte 11a, 11b zwischen diesen Stutzen und endseitigen Stirnflächen beider Gehäuseteile der Darstellung entsprechend befin den, um diese gegenüber der Aufnahme und dem Kanal 10 abzudichten. Durch mehr oder weniger starkes Verschrauben des Gehäuseteils 5 auf den Gewindestut zen des Gehäuseteils 4 hat man es in der Hand, Einfluß auf die Funktion und Wirkung dieser beiden Dichtungen zu nehmen.The housing part 4 is provided with a cylindrical recess as a receptacle 7 for a cartridge 8 . This consists of a rigid support 9 with an axially continuous channel 10 and a channel 10 passing through the tube 11 , which is so reversed at its two end regions in each case via a nozzle of the carrier 9 that tube sections 11 a, 11 b between these nozzles and the end faces of both housing parts as shown in order to seal them from the receptacle and the channel 10 . By more or less strong screwing of the housing part 5 on the threaded socket of the housing part 4 it is in your hand to influence the function and effect of these two seals.
Im Gehäuse bzw. im ersten Gehäuseteil 4 und auch im Träger 9 ist jeweils ein Durchgang 12 bzw. 13 für ein Sperrelement 14 vorgesehen, wobei der Durchgang 13 im Träger 9 so groß ausgebildet ist, daß ausreichend Platz für eine Rückverfor mung des Schlauches 11 beim Öffnen des gesperrt dargestellten Ventils vorhanden ist. In the housing or in the first housing part 4 and also in the carrier 9 , a passage 12 or 13 is provided for a locking element 14 , the passage 13 in the carrier 9 is so large that sufficient space for a Rückverfor tion of the hose 11 at Opening the valve shown locked is present.
Das Sperrelement 14 ist als Stößel ausgebildet, der bei 15 an einem Hebel 16 mit dem erforderlichen Spiel angelenkt ist und im Durchgang 12 des Gehäuseteils 4 radial geführt ist.The locking element 14 is designed as a plunger, which is articulated at 15 on a lever 16 with the required play and is guided radially in the passage 12 of the housing part 4 .
Der Hebel 16 ist um ein Lager 17 verschwenkbar gelagert und mit einer Feder 18 in Bezug auf die Darstellung so im Uhrzeigersinn vorgespannt, daß er den Stößel 14 selbsttätig in Richtung auf den Schlauchumfang drückt und dieser den Schlauch wie dargestellt zwecks Sperrens des Ventils elastisch verformt.The lever 16 is pivotally mounted about a bearing 17 and is biased clockwise with a spring 18 with respect to the illustration that it presses the plunger 14 automatically towards the circumference of the hose and this elastically deforms the hose as shown for the purpose of locking the valve.
Durch von Hand ausgeübten Druck auf den Hebel 16 wird dieser entgegengesetzt dem Uhrzeigersinn um sein Lager 17 verschwenkt. Er zieht dabei den Stößel 14 radial im Durchgang 12 nach außen, so daß sich der Schlauch dabei elastisch zu einem insgesamt zylindrischen Gebilde rückverformen wird und Fluid über den Schlauchanschlußstutzen 5a ungehindert durch den Kanal 10 und den Durchgang 4b des Gehäuseteils 4 zum Instrument strömen kann. Umgekehrt wird das Ventil wieder selbsttätig schließen, wenn der auf den längeren Arm des Hebels 18 ausge übte Druck aufgehoben wird.By hand pressure on the lever 16 , this is pivoted counterclockwise about its bearing 17 . He pulls the plunger 14 radially in the passage 12 to the outside, so that the hose will resiliently reshape to form an overall cylindrical structure and fluid flows freely via the hose connector 5 a through the channel 10 and the passage 4 b of the housing part 4 to the instrument can. Conversely, the valve will automatically close again when the pressure exerted on the longer arm of the lever 18 is released.
Abschließend wird noch darauf hingewiesen, daß mit dem erfindungsgemäßen Quetschventil nicht nur der Durchfluß von Fluiden gesteuert werden kann, sondern ebenfalls durch das Quetschventil hindurchgeführte Hilfsinstrumente durch Fest klemmen positioniert werden können, wobei im übrigen auch die Hilfsinstrumente unterschiedliche Durchmesser haben können.Finally, it is pointed out that with the invention Pinch valve can not only control the flow of fluids, but auxiliary instruments also passed through the pinch valve through fixed clamps can be positioned, with the rest also the auxiliary instruments can have different diameters.
