Abstract
System zum Messen des Drucks in einem Gefäß eines Patienten, mit einem implantierten Port, das mit einem von einer Kanüle durchstechbaren Septum und einem Katheteranschluss versehen ist, einem an das Katheter, dessen proximales Ende an den Katheteranschluss angeschlossen und dessen distales Ende in das Gefäß geführt ist, einer das Septum durchstechenden Kanüle und einem mit einem Drucksensor versehenen externen, mit der Kanüle verbunden Druckmessgerät.A system for measuring pressure in a patient's vessel, comprising an implanted port provided with a cannula pierceable septum and a catheter port, one to the catheter, the proximal end of which is connected to the catheter port, and the distal end of which is guided into the vessel is a cannula piercing the septum and a pressure gauge connected to the external, connected to the cannula pressure gauge.
Description
Die Erfindung betriff ein System zum Messen des Drucks in einem Gefäß eines Patienten unter Verwendung eines implantierbaren Ports, das mit einem von einer Kanüle durchstechbaren Septum und einem Katheteranschluss versehen ist, und mit einem Katheter, dessen proximales Ende in ein Gefäß des Patienten eingeführt ist.The invention relates to a system for measuring the pressure in a patient's vessel using an implantable port provided with a cannula pierceable septum and a catheter port, and a catheter having its proximal end inserted into a vessel of the patient.
Es ist häufig erwünscht, den Druck in einem Gefäß, insbesondere in einem Blutgefäß, beipielsweise dem Herzen, zu bestimmen.It is often desirable to determine the pressure in a vessel, especially in a blood vessel, such as the heart.
Die dazu heute insbesondere in der Intensivmedizin verwendeten Techniken sind aufwendig und für Langzeituntersuchungen nicht geeignet.The techniques used today especially in intensive care medicine are complex and not suitable for long-term investigations.
Der Erfindung liegt damit die Aufgabe zugrunde, ein System zu schaffen, das es erlaubt, den Druck in einem Gefäß eines Patienten in bestimmten Zeitabständen (Wochen oder Monaten) zu messen und so den Erfolg einer Therapie zu überprüfen.The invention is therefore based on the object to provide a system that allows to measure the pressure in a vessel of a patient at certain intervals (weeks or months) and thus to verify the success of a therapy.
Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des Anspruchs 1 gelöst, der Anspruch 2 gibt eine bevorzugte Ausgestaltung an.According to the invention this object is achieved with the features of claim 1, the claim 2 indicates a preferred embodiment.
Erfindungsgemäß wird also vorgeschlagen, ein System zum Messen des Drucks in einem Gefäß eines Patienten zu schaffen, das mit einem implantierten Port, welches mit einem von einer Kanüle durchstechbaren Septum und einem Katheteranschluss versehen ist, einzusetzen. An den Katheteranschluss ist das proximale Ende eines Katheters angeschlossen, dessen distales Ende in das Gefäß geführt ist. Es ist weiter ein externes Druckmessgerät vorgesehen, das mit einem Drucksensor versehen und mit einer Kanüle, die das Septum durchsticht, verbunden ist.According to the invention, it is therefore proposed to provide a system for measuring the pressure in a vessel of a patient, which is provided with an implanted port, which is provided with a pierceable by a cannula septum and a catheter connection. Connected to the catheter port is the proximal end of a catheter whose distal end is guided into the vessel. There is further provided an external pressure gauge provided with a pressure sensor and connected to a cannula piercing the septum.
Der Druck in dem Gefäß, in das das distale Ende des Katheters eingebracht ist, kann auf diese Weise wiederholt extern gemessen werden, wobei es lediglich eines Durchstechens des Septums des Ports, also eines nicht erheblichen Eingriffs in den Körper des Patienten bedarf. Das Druckmessgerät kann auch so ausgebildet sein, dass es nicht nur den Druck in dem Katheter misst, sondern darüber hinaus auch analysiert.The pressure in the vessel into which the distal end of the catheter is inserted can thus be repeatedly measured externally, whereby only a puncture of the septum of the port, that is, a non-significant intervention in the body of the patient needs. The pressure gauge may also be designed not only to measure the pressure in the catheter, but also to analyze it.
Bei einer bevorzugten Ausführungsform ist das Druckmessgerät auch dazu geeignet, das Fluid in dem System zu asperieren, um festzustellen, ob das distale Ende des Katheters sich noch in dem Gefäß befindet, und um sich in dem System angesammelte Luft zu entfernen. Das Druckmessgerät kann weiter auch ein Fluid in den Schlauch, der diesen mit der Kanüle verbindet, abgeben, wobei es sich bei dem Fluid um beispielsweise Kochsalzlösung handelt, die dazu dient, das distale Ende des Katheters falls erforderlich frei zu spülen oder aber um ein am Ort des distalen Endes des Katheters wirkendes Medikament zu applizieren.In a preferred embodiment, the pressure gauge is also adapted to aspirate the fluid in the system to determine if the distal end of the catheter is still in the vessel and to remove air accumulated in the system. The pressure gauge may also deliver a fluid into the tube connecting it to the cannula, which fluid is, for example, saline, which serves to flush the distal end of the catheter, if necessary, or at least one am Applicable drug applied to the site of the distal end of the catheter.
