Description
Ballonkatheter Die Erfindung betrifft einen Ballonkatheter zur Entnahme von Pankreas und Magensaft, Es ist bekannt, Katheter für längere Verweildauer aus Weichgummi oder Kunststoff zu fertigen und an der Spitze mit einem aus dünnem Gummi hergestellten aufblasbaren Ballon zu versehen, der nach Einführen des Katheters in die Kdrperhdhle mit Flüssigkeit oder Gas gefüllt wird und als Fixierung des Katheters in der Körperhöhle bzw, als Abdichtung gegen die innere Höhlenwand dient. Zu diesem Zweck ist der Ballon über einen Kanal mit einer entsprechenden Flüssigkeits- oder Gasfördereinrichtung verbunden.Balloon Catheter The invention relates to a balloon catheter for extraction of pancreas and gastric juice, it is known to catheter out for longer residence times Soft rubber or plastic to manufacture and on top with a thin rubber manufactured inflatable balloon after insertion of the catheter in the body cavity is filled with liquid or gas and as a fixation of the catheter in the body cavity or as a seal against the inner cavity wall. To this Purpose is the balloon via a channel with a corresponding fluid or Gas conveyor connected.
Es ist weiterhin ein Katheter bekannt geworden, bei dem im Abstand zum ersten Ballon ein zweiter Ballon angeordnet und über einen separaten Kanal mit einer Gasfördereinrichtung verbunden ist. Zur Verbesserung der Einführungseigenschaften haben die Ballonhüllen den gleichen Durchmesser wie die einzuführende Katheterleitung, so daß es -auf der Katheteroberfläche nur minimale Niveauunterschiede bzw, Verwölbungen gibt. Mit den bekannten 2-Ballonkathetern zur Gewinnung von Pankreassaft ist es nicht möglich, gleichzeitig Magensaft auszuhebern. Diese Tatsache hat drei Nachteile; Erstens kommt es bei der Untersuchung durch die gleichzeitige verstärkte Magensaftbildung zu einer zusätzlichen Belastung des Patienten, die u.U. zu einem vorzeitigen Abbruch der Untersuchung führt0 Zweitens kommt es bei der meist nicht vollständigen Abdichtung des Magenausgangs (Pylorus) durch den ent-Sprechenden Ballon zu einem Zufluß von Magensaft in den Duodenalraum. Das führt zu einer salzsäurebedingten Enzyminäktivierung des Pankreassaftes, was UngenauWkeit und Verfälschung der Diagnose hervorruft.A catheter has also become known in which at a distance a second balloon is arranged for the first balloon and via a separate channel a gas delivery device is connected. To improve the introduction properties the balloon covers have the same diameter as the catheter line to be inserted, so that there are only minimal differences in level on the catheter surface respectively, Warping there. With the well-known 2-balloon catheters for the extraction of pancreatic juice it is not possible to evacuate gastric juice at the same time. This fact has three Disadvantage; First, it comes through the simultaneous enhanced examination Gastric juice formation creates an additional burden on the patient, which may result in a premature termination of the examination leads to secondly, it usually does not occur complete sealing of the gastric outlet (pylorus) by the corresponding balloon to an influx of gastric juice into the duodenal space. This leads to a hydrochloric acid-related Enzyme inactivation of the pancreatic juice, resulting in inaccuracy and falsification of the diagnosis evokes.
Da im Rahmen der Oberbauchdiagnostik, welche die Untersuchung der exkretorischen Funktion des Pankreas mittels Duodenalsondierung einschließt, auch eine Magensekretionsanalyse unerläßlioh ist, besteht der dritte Nachteil darin, daß sich der Patient zur Magensaftuntersuchung einer zusätzlichen Sondierung unterziehen muß.As part of the upper abdominal diagnosis, which is the examination of the excretory function of the pancreas by means of duodenal probing includes, too a gastric secretion analysis is essential, the third disadvantage is that that the patient undergo an additional probe for gastric juice examination got to.
Bin weiterer Nachtei-l der bekannten Doppelballonkatheter besteht in der langen Sondierungszeit. Diese beruht cauf den Niveauunterschieden zwischen Ballon- und Katheteroberfläche, was die Passage des Magenausgangs erschwert und verlängert, u. U.Another disadvantage is the well-known double balloon catheter in the long exploratory period. This is based on the level differences between Balloon and catheter surface, which complicates the passage of the gastric outlet and extended, possibly
unmöglich macht. daraus ergibt sich eine entsprechend hohe Strahlenbelastung für den Patienten, da die Sondenlage röntgenologisch bestimmt werden muß. Zweck der Erfindung ist es deshalb, die Untersuchungsinethode durch kürzere Sondierungszeit, genauere Diagnose und geringere Patientenbelastung zu verbessern. Daraus ergibt sich die Aufgabe, den Doppelballonkatheter konstruktiv so zu verändern, daß die Passagezeit am Magenausgang verkürzt und parallel zur Duodenalsondierung eine Magensaftausheberung erfolgen kann.makes impossible. this results in a correspondingly high radiation exposure for the patient, since the position of the probe must be determined radiologically. purpose the invention is therefore to improve the investigation method through shorter probing time, improve more accurate diagnosis and lower patient exposure. From this it follows the task of changing the design of the double balloon catheter so that the The passage time at the gastric outlet is shortened and gastric juice is extracted parallel to the duodenal probing can be done.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß im einzuführenden Katheterrohr zwei separate Kanäle unterschiedlicher Länge angeordnet sind und daß in Betriebsstellung die Öffnung des verlängerten Xatheterkanals innerhalb des Duodenum im Mündungsbereich des Pankreas und die Öffnung des kurzen Katheterkanals im Magensekretbereich liegt. Dadurch ergibt sich der Vorteil, den für die exakte Gewinnung von Pankreasaft störenden Magensaft gleichzeitig kontinuierlich und fraktioniert ausheben zu können und somit diagnostisch zu verwenden.According to the invention the object is achieved in that the to be introduced Catheter tube two separate channels of different lengths are arranged and that in the operating position, the opening of the extended xatheter canal within the duodenum at the mouth of the pancreas and the opening of the short catheter channel in the gastric secretion area lies. This results in the advantage that for the exact extraction of pancreatic juice disturbing gastric juice at the same time continuous and fractionated dig to be able to use it diagnostically.
Es wird eine wesentliche Herabsetzung der Sondierungszeit und in einigen Fällen überhaupt eine Duodenalsondierung möglich. Weiterhin wird dadurch eine exaktere Diagnose erzielt und u.U. eine falsche vermieden. Es ergibt sich somit eine geringere Belastung für den Patienten infolge kürzerer Untersuchungszeit, Wegfall der durch Magensaftanhäufung bedingten Beschwerden, geringere Strahlenbelastung, Wegfall von Wi ederholungsunt er su chungen und Ersparung einer zusät zlichen Magensondierung zwecks Sekretionsanalyse.It will significantly reduce the exploratory time and in some In some cases, duodenal probing is possible at all. This also makes it more precise Diagnosis achieved and possibly an incorrect one avoided. The result is a lower one Stress for the patient as a result of shorter examination time, elimination of the Symptoms related to gastric juice accumulation, lower radiation exposure, elimination of Recuperation exercises and avoidance of an additional gastric probe for secretion analysis.
Zur Verringerung des Eatheterdurchmessers kann nur ein Luftkanal vorgesehen werden, an dem beide Fixierballone gemeinsam angeschlossen sind. Es ist weiterhin zweckmäßig, einen Ballon vor und einen Ballon hinter der Öffnung des verlängerten Katheterkanals am Eatheterrohr anzuordnen. Dabei sollte angestrebt werden, den Durchmesser der entspannten Ballonhüllen gleich dem des einzuführenden Katheterrohres zu gestalten, so daß auf der Katheteroberfläche keine Vorwölbungen oder Ausstülpungen entstehen.Only one air channel can be provided to reduce the diameter of the catheter to which both fixing balloons are connected together. It is still expediently, a balloon in front of and a balloon behind the opening of the elongated To arrange catheter channel on the catheter tube. The aim should be the diameter to make the relaxed balloon envelope the same as that of the catheter tube to be inserted, so that no protrusions or protuberances arise on the catheter surface.
Die Erfindung soll nachstehend an einem Ausfübrungsbeispiel naher erläutert werden: Das Katheterrohr 1 besteht aus den Kanälen 2; 3 mit den Öffnungen 4; 5 und den im Abstand voneinander angeordneten Pixierballons 6; 7 sowie dem Luftkanal 8.The invention is to be closer to an exemplary embodiment below are explained: The catheter tube 1 consists of the channels 2; 3 with the openings 4; 5 and the spaced-apart pixier balloons 6; 7 and the air duct 8th.
In Betriebsstellung des Ballonkatheters liegt die Öffnung 4 im Magensekretbereich 9 und die Öffnung 5 im Mündungsbereich 10 des Pankreas 11 im Duodenum 12. Dabei ist ein Fixierballon 6 vor und ein Fixierballon 7 hinter dem Mündungsbereich 10 des Pankreas 11 am Eatheterrohr 1 angeordnet, welche im geblähten Zustand am Duodenum 12 dichtend anliegen und den Mündungsbereich 10 des Pankreas 11 vom übrigen Duodenum 12 isolieren.In the operating position of the balloon catheter, the opening 4 lies in the gastric secretion area 9 and the opening 5 in the mouth region 10 of the pancreas 11 in the duodenum 12 is a fixation balloon 6 in front of and a fixation balloon 7 behind the mouth area 10 of the pancreas 11 arranged on the catheter tube 1, which in the inflated state on the duodenum 12 lie tightly against the mouth area 10 of the pancreas 11 from the rest of the duodenum Isolate 12.
