Abstract
Description
Diese Erfindung betrifft eine Einrichtung zur Punktion und Katheterisierung des Periduralraumes und des Rückenmarkkanals, sowie Verfahren zu dessen Betrieb.These The invention relates to a device for puncture and catheterization the peridural space and spinal canal, and methods for its operation.
Üblicherweise wird zur Punktion des Periduralraumes eine Toyo-Nadel mit einer aufgesetzten und mit Flüssigkeit gefüllten Spritze verwendet. Zur Identifizierung des Periduralraumes werden verschiedenen Verfahren verwendet. Eines davon ist das Verfahren nach Widerstandsverlust der Spritzkolbe bei dessen ständiger manuellen Betätigung während dem vorsichtigen Vorschieben der Punktionsnadel in Richtung des Periduralraumes.Usually is used to puncture the peridural space a Toyo needle with a put on and with liquid filled Syringe used. To identify the peridural space used different methods. One of them is the procedure after loss of resistance of the piston with its constant manual Actuation during the gently advancing the puncture needle in the direction of the peridural space.
Das oben beschriebene Set und Verfahren haben folgende Nachteile:
- – aufgrund subjektiver Einschätzung des Widestandsverslustes vom Anästhesisten und besonders bei geringem Widerstand der zu punktierenden Weichteilen und Bindegeweben in Richtung des Periduralraumes und selbst des Periduralraum es, wird das Periduralraum nicht immer sicher erkannt, was zu einer fehlerhaften Katheterisation führen kann. Bei weniger erfahrenen Anästhesisten steigt diese Gefahr wesentlich an, da eine fehlerhafte Katheterisation gravierende Folgen für den Patient haben kann
- – die Vielzahl von anderen Verfahren zur Identifizierung des Periduralraumes, wie zum Beispiel „hängender Tropf verringern die Gefahr nicht
- – da der Anästhesist während der Punktion damit beschäftigt ist, den Widerstand der Spritzkolbe ständig Millimeter für Millimeter manuell prüfen zu müssen, indem er die Beweglichkeit der federnder Kolbe beim leichten Druck auf die Kolbe einzuschätzen versucht, kann er sich nicht vollständig auf die Punktion konzentrieren
- – die Spritze muss häufig von der Nadel getrennt und mit weiteren Mengen von Flüssigkeit gefüllt werden, was die Gefahr einer Infizierung steigert
- – das Verstopfen der Nadel mit Geweben während dem Vorschieben und dadurch eine erhöhte Gefahr der Duraperforation kann nicht immer erkannt werden
- - Based on subjective assessment of the anesthesiologist's reluctance to relinquish his condition and especially with little resistance of the soft tissue and connective tissue to be punctured in the direction of the peridural space and even the peridural space, the peridural space is not always reliably recognized, which can lead to erroneous catheterization. For less experienced anesthesiologists, this risk increases significantly, as faulty catheterization can have serious consequences for the patient
- - The variety of other methods for identifying the peridural space, such as "hanging drip, does not reduce the risk
- - Since the anesthesiologist is busy during the puncture to manually check the resistance of the spray piston millimeter by millimeter by trying to estimate the mobility of the resilient piston with slight pressure on the piston, he can not fully concentrate on the puncture
- - The syringe must be frequently separated from the needle and filled with additional quantities of liquid, which increases the risk of infection
- - The clogging of the needle with tissues during advancement and thus an increased risk of Duraperforation can not always be detected
Es ist daher Aufgabe der vorliegenden Erfindung, eine Einrichtung bzw. Verfahren zu dessen Betrieb zur Verfügung zu stellen, welche das Einbringen der Punktionsnadel und bzw. eines Katheters in den Periduralraum oder in den Rückenmarkkanal erleichtert und sicherer macht, versehentliche Duraperforationen ausschließt und Beschädigungen des Rückenmarkes reduziert.It is therefore an object of the present invention, a device or To provide a method for its operation, which the Inserting the puncture needle and / or a catheter into the peridural space or in the spinal canal makes it easier and safer, accidental dura perforations excludes and damage of the spinal cord reduced.
Die Lösung dieser Aufgabe erfolgt bezüglich der Einrichtung durch die Merkmale des Anspruches 1 bis 5.The solution This task is done with respect to Device by the features of claim 1 to 5.
Mit dieser Erfindung wird die Aufwendigkeit der manuellen Identifikation des Periduralraumes und des Rückenmarkkanals erleichtert und vereinfacht. Das wird durch eine indirekte kontinuierliche Messung der Druckschwankungen im Innenlumen der Punktionsnadel erreicht, welche nach Druckabfall in einem zwischen der Spritzkolbe und einem Druckerzeuger angebrachten geschlossenen elastischen Raum entstehen, von einem Druckmeßsystem ermittelt werden und beim Erreichen des Periduralraumes optisch und akustisch den Anästhesisten benachrichtigen. Außerdem, schließt diese Einrichtung eine Kontamination (Infizierungsgefahr des Periduralraumes) völlig aus. Der Verlängerungsschlauch zwischen der Einrichtung und der Punktionsnadel sorgt für Mobilität während der Punktion und schränkt die Beweglichkeit der Nadel nicht ein. Da die Identifizierung des Periduralraumes vollautomatisch vom Meßsystem übernommen wird, werden für den Anästhesisten sämtliche Bedienungen geschaffen sich nur auf die Punktion zu konzentrieren. Nach Erreichen des Periduralraumes wird der Druck auf die Spritzkolbe automatisch eingestellt.With This invention takes the effort of manual identification of the peridural space and the spinal canal relieved and simplified. This is done by an indirect continuous measurement the pressure fluctuations in the inner lumen of the puncture needle achieved which after pressure drop in a between the spray piston and a Pressure generator attached closed elastic space arise determined by a pressure measuring system and on reaching the peridural space optically and acoustically the anesthesiologist notify. in addition, includes this device a contamination (risk of infection of the peridural space) completely out. The extension tube between The device and the puncture needle ensures mobility during the puncture and restricts the Mobility of the needle not one. Because the identification of the peridural space fully automatically adopted by the measuring system will be for the anesthesiologist all Operations created only to focus on the puncture. After reaching the peridural space, the pressure on the Spritzkolbe automatically set.
Die einfache Steuerung sorgt für eine optimale Bedienungsfreundlichkeit für das medizinische Personal.The simple control ensures optimal ease of use for the medical staff.

Die Punktion und Katheterisation des Rückenmarkkanals unterscheidet sich von der Punktion und Katheterisation des Periduralraumes nicht. Zu beachten sind lediglich unterschiedliche Enddruckergebnise und dass, bei der Durapunktion ein zweiter Druckabfall entstehet und aus der Punktionsnadel Liquor frei herauslauft.The Puncture and catheterization of the spinal canal is different not from the puncture and catheterization of the epidural space. Please note only different final printer results and that, in the Durapunktion a second pressure drop arises and from the puncture needle Liquor freely runs out.
