Abstract
Description
Die Erfindung betrifft eine implantierbare Infusionspumpe, dessen Gehäuse eine von einem Bolusseptum verschlossene Boluskammer aufnimmt.The The invention relates to an implantable infusion pump whose housing picks up a bolus chamber closed by a bolus septum.
Derartige
implantierartige Infusionspumpen sind vielfältig bekannt,
auf die
Die von dem Bolusseptum verschlosssene Boluskammer kommuniziert mit einem Katheter, das zu dem Wirkort im Patienten führt. Bei einem Durchstechen des Bolusseptums kann ein Medikament so unter Umgehung der Drosselstrecke, mit der implantierbare Infusionspumpen versehen sind, dem Patienten zugeführt werden.The Bolus septum closed by the bolus septum communicates with a catheter that leads to the site of action in the patient. When piercing the Bolusseptums a drug so under Bypassing the choke line, using the implantable infusion pumps are provided, are supplied to the patient.
Insbesondere aber dient die Boluskammer auch dazu, die Durchgängigkeit des Katheters zu überprüfen, indem unter Verwendung eines bildgebenden radiographischen Verfahrens ein Kontrastmittel in die Boluskammer und damit in den Katheter eingebracht wird.Especially but the bolus chamber also helps to ensure patency of the catheter by using an imaging radiographic method, a contrast agent is introduced into the bolus chamber and thus into the catheter.
Es besteht nun die Gefahr, dass bei der Gabe von Kontrastmittel die Boluskammer nicht erreicht wird, in diesem Fall gelangt das Kontrastmittel in das die Infusionspumpe umgebende Gewebe des Patienten, eine – tatsächlich gegebene – Durchgängigkeit des Katheters wird durch das bildgebende Verfahren nicht erkennbar.It there is now the danger that when administering contrast agent the Bolus chamber is not reached, in this case, the contrast medium enters the tissue surrounding the infusion pump of the patient, a - actually given - patency of the catheter becomes not recognizable by the imaging process.
Der Erfindung liegt die Aufgabe zugrunde, eine implantierbare Infusionspumpe zu schaffen, bei der bei Geben eines Kontrastmittels unter Verwendung eines bildgebenden radiographischen Verfahrens die Boluskammer und damit die richtige Platzierung der Kanüle, mit der das Kontrastmittel in die Boluskammer eingeführt wird, erkennbar wird.Of the Invention is based on the object, an implantable infusion pump to create when using a contrast agent using an imaging radiographic procedure, the bolus chamber and Thus, the correct placement of the cannula, with which the Contrast agent is introduced into the bolus chamber, recognizable becomes.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die radiographische Dichte des Gehäuses im Bereich der Boluskammer höher ist als im übrigen Bereich.According to the invention solves this problem by the fact that the radiographic Density of the housing in the area of the bolus chamber higher is as in the rest of the range.
Bevorzugte Ausführungsbeispiele zeichnen sich dadurch aus, dass das Bolusseptum mit einem pulverisierten Material mit hoher radiographischer Dichte versetzt ist, dass das Bolusseptum von einem Ring aus einem Material mit hoher radiographischer Dichte umgeben ist, dass der Boden der Boluskammer mit einem Ring oder einer Platte aus einem Material mit hoher radiographischer Dichte belegt ist und/oder dass die Wandung der Boluskammer mit einem Material mit hoher radiographischer Dichte besteht.preferred Embodiments are characterized in that the Bolus septum with a pulverized material with high radiographic density The bolus septum is offset from a ring of a material surrounded with high radiographic density is that the bottom of the Bolus chamber with a ring or plate of a material is occupied with high radiographic density and / or that the wall the bolus chamber with a material of high radiographic density consists.
Beispiele eines derartigen radiopaken Materials sind Bariumsulfat, Wismuttrioxid, Jod, Jodid, Zirkonoxid, Gold, Platin, Silber, Tantal, Niob und rostfreier Stahl.Examples of such a radiopaque material are barium sulfate, bismuth trioxide, Iodine, iodide, zirconia, gold, platinum, silver, tantalum, niobium and stainless Stole.
